A bit of an image film, but the principle is being conveyed quite nicely. These are designed to act as disposable plates. In india plastic/styrofoam disposable plates are being used a lot, so this is a viable alternative. The principle works as well for banana leaf, banana trunk, areca palm front and probably many more cellulose based materials. https://m.youtube.com/watch?v=QWQ9iAA8KdA

@Jannis // Beyond Plastic Have you tried hot liquids in any of the cups? (edited)

I'm also wonder about finishing - disposable cups are tough competition where I am

Did you already have bowls or plates done? I put orange peels on the oven at low temperature to dehidrate them, smashed it on the mixer, the next step is to put a little bit of water and press it on the heater to have a sheet? Im trying to do this right

@aditya24786, did you find the download link? Dave pinned it to the channel

@protohub, great question! I put hot coffee in it a few times to test. (hot liquid is pretty much the biggest challenge I think!) So far the cup held for about 5 minutes before starting to break. I guess more of an espresso cup

‍♂️ However, the walls of the cup are very thin right now (roughly 1.5mm). The next steps would be to make them a big thicker and see how it reacts to it. Other options would be to look more into coatings, however it’s quite a challenge to create heat and water resistant coatings that biodegrade. Anyways, I’m working on it. And if you are as well, let’s work together on it!

6:34 PM

@Kattapa-JU: Finishing would be a great thing to look into next. I think there are a lot of different options (wax, oils, agar-agar or gelatine-bioplastics, etc.), but I haven't managed to look into it yet. Do you have anything specific in mind already?

6:34 PM

And by the way: where are you?

6:39 PM

@TioRodrigues: Nice to see you already working on it! We made cups, bowls and sheets so far. You can see how we did it in the videos or the material book in the download kit. Anyways, we found, that it makes a big difference, whether you press the material in a mould that allows water to evaporate or a closed mould, since the closed mould gives you a much stronger binding within the material. So it’s good to have a mould that can compress the material, while being almost airtight. (did you look at how we build the moulds in the download kit?)

6:40 PM

and the amount of force you use also makes a big difference... What kind of a press are you using?

@Jannis // Beyond Plastic nothing in mind just thinking from a business stand point. Ghana has a high rate of disposable cup usage. It would be tough to challenge that in the market without a quality finish

6:48 PM

the only real issue, from a first glance, is the tops of the cups that have been pressed in the machine - the body looks great as is. So perhaps a wax that could make a even lip to the cup - not sure how agar-agar or gelatin would hold up to alcoholic beverages - since thats what the are generally used for here

@Kattapa-JU: oh nice! didn't have those on the radar yet. (over here everyone is just asking for coffee cups always

) The top of the cup is a bit of a challenge, since it's also not easy to create a mould that gives them a round finish on the lip. Especially on the lathe.

7:02 PM

I guess it could be done after the pressing, but that is more work again...

7:04 PM

In general it's going to be tough to compete with industrially-made products (I think it's the same for PP plastic products as well).

7:06 PM

But we tried to keep the production cost with the beyond plastic stuff as low as possible and I do think that the aesthetics of the materials are different enough to enable a higher price then "normal" disposable plastic products.

7:07 PM

btw: In which situations are people using disposable cups most in Ghana?

7:08 PM

and what kind of alcoholic beverages are they drinking? (so I can do future test with that as well

)

@Jannis // Beyond Plastic Industrial products are cheap and perfect, though i believe the beyond plastics approach is showing promise!

7:13 PM

The problem with the idea of a higher price in Ghana is that it takes most of your market out of the picture - It make work with certain classes in large urban centres but thats not most of the country. Perhaps there could a round cover at the top of the mold that would push the organic material into it and make a rounded finish, if you can envision that without a drawing?

7:13 PM

Most cups are used for beer and hard liquor - up to 80%

@Kattapa-JU: I'd doubt they are 'perfect', since they are making a pretty big mess on this planet, but that's just a side note

7:17 PM

I can imagine, what you mean and have already thought about it quite a bit, but I still think it would be actually pretty hard to make a mould with a 'counter'-round lip, if you can imagine what I mean?

7:17 PM

and I totally agree on everything you say!

7:18 PM

It would be amazing to find a way to make things like this available to everyone and not just a small group

@Kattapa-JU hi, out of interest, what are the typical usecases for using disposable cups that you have in mind? Do people se them in pubs/bars indoors?

@Arseniy (PL) I was about to ask the same question

I imagine it's not just street food stands since hard liquor was mentioned

7:19 PM

or there is a wide cultural gap

and @Kattapa-JU: another way to push the prices would be to make more cups in one go. Here I think it's interesting to keep in mind that placing moulds next to each other would require more pressure with every mould. But if you stack them on-top of each other, it would work with pretty much the same amount.

7:23 PM

and @Arseniy (PL): where are you from?

@Jannis // Beyond Plastic actually, maybe you can do 'matryoshka' stacking to make a set at once

7:24 PM

I'm from Poland. Is there a way to put this informatio in the profile here or something?

good thought! I actually always wanted to make a bowl together with cutlery in one mould. Like "spoon - bowl - knife" or whatever people locally prefer

yup, sets actually make a great sense also as a gift idea

I'm from Poland. Is there a way to put this informatio in the profile here or something?

@Arseniy (PL) unfortunately I don't think it's possible on here -.-

@Arseniy (PL) @Jannis // Beyond Plastic its used in all places where alcohol is served - its kind of a cultural attitude to use a disposable cup because nobody else has used it and its nice looking (thats what i meant by perfect

). So the high end, the medium, and the budget spots (yes there are street stands that sell hard liquor)

@Kattapa-JU thanks! could I bother you to find a picture on google that shows typical disposable cup that is used in Ghana? The ones I have in mind aren't particularly 'nice looking' and are quite flimsy

I can, i'll go for a drink tomorrow and take one, now that i have a reason! - perhaps we have a different idea of nice ahaha, they are just clear PP cups, its more the idea that they are factory fresh that makes them nice to people in Ghana!

Oh I see, thx.

7:52 PM

In that case, I'm thinking now, cardboard/carton cups produced professionally at high volume have much better chances to displace PP cups

another common use once and destroy product - besides the block polythene bags, are the take away styrofoam packs with the top and bottom attached - would be more challenging than bowls and cups. Perhaps for V5!?

7:54 PM

Would cardboard/carton cups be produced in the same way?

re:cardboard I think so - just pressing old soggy shredded paper into mold. no binder/heating needed as far as I remember

8:04 PM

Recycle Cardboard into Anything with 3D Printing!

1

Yeah, paper cups are definitely also interesting. The issue with the ‘paper’-cups that are used usually is that their inside is coated with a thin layer of plastic. This makes them non-biodegradable and recycling basically impossible.

1

8:13 PM

But paper waste would definitely also work in the pretty well in the moulding process

8:14 PM

Another thing I already tested, but didn’t get to dive into really deep is using leaves like they already do in a lot of places

8:15 PM

But so far the process of thermoforming the leaves (we used rice leaves) worked very well in the Bio Presse, so it’s definitely something worth looking into

1

8:19 PM

@Kattapa-JU: we actually made a mould for a to go container in the development of V4 already. However it didn’t make it into the download kit, since the mould turned out to be a bit to complicated to actually work reliably.

8:22 PM

There’s a picture of it on this article

@Jannis // Beyond Plastic Thanks for that! will give it a read now

8:33 PM

the shot cups in the article look good!

Maybe the solution is to not use disposable items at all. I carry a collapsible silicon cup with me, when I'm out and about. It's made for camping. I've made a foldable cardboard insulator for it, so that I can hold hot and very cold drinks. At about USD5 ($5), I think a lot of people won't throw it in a bin, but rather keep it for re-use. It also works for festivals, because it is a soft material (in case trouble-makers start throwing their drinks.) I'm trying to upload pictures, but Discord's AI thinks it's "explicit content."

(edited)

8:36 PM

8:37 PM

Haha, feels kind of good to know that AI is still at a point where it thinks this is a nipple;)

I think in a perfect world I’d agree with you. I would even argue, you don’t need “to-go” at all, buuuut being realistic, people will want to have disposable objects. And for those, it should be a goal to make them at least biodegradable

8:40 PM

And I feel like that’s actually something achievable. That’s why I’m working on this

@Frederik C (ZA) agreed! you have done well do use a container that is not disposable. Implementing would require some type of law, that could be enforced, and behavioural change programs. Would be difficult with all of the lobbying power from the industry.

@Jannis // Beyond Plastic btw, if we are talking broadly alternative materials, do you have any experience with kombucha's scoby?

9:14 PM

I did some experiments with it, but rather as a leather substitute. Results were quite promising but far from ready product. One intersting thing about it is that it can be made into almost transparent film (yellow-brown tinted, more like 'frosted glass' kind of transparent) which was pretty strong/durable

9:15 PM

I think it's quite important to come up with some biodegradable alternative to a transparent plastic - that's a huge advange of plastic which makes it so ubiquitous in packaging - you can actually see what's wrapped/inside the container.

being realistic, people will want to have disposable objects I think it depends on the type of object and public consciousness. In South Africa, we don't have any legal plastic bans yet, but a fast-food chain I regularly visit, has voluntarily stopped supplying drinking straws (and never supplied cups to begin with.) And customers accept it. The attitude shift starts with business owners and consumer activism.

@Frederik C (ZA) not sure what's your point here exactly - is it that we shouldn't work on developing biodegradable disposable items?

Yeah, I agree completely and I’m excited to hear that slowly things are changing. Still, I think making products degradable should be a focus in general. It’s simply worth looking into harmless materials to substitute today’s materials, since there are so many issues connected to the additives involved making them.(Thinking about MDF or chipboards boards for example)

1:06 AM

And btw. What’s the name of the fast food chain? I’m always happy to have more examples of companies pushing change on their own:)

It's Romans Pizza. I don't know if they have stores internationally. I think they still use clear plastic punnets for salads, unfortunately. But otherwise all their containers are cardboard or aluminium foil.

2:25 AM

@Arseniy (PL) I guess my point is that the first "R" of the "3 Rs" is "Reduce." And there's a reason that it comes before "Reuse" and "Recycle."

I'm not sure how common pizza joints are in South Africa but Ghana pizza is for those with money, meaning a certain class of people - not the working class majority. My question is should it start from there as an ideal of reducing plastic waste and then, as social studies tell us, move down into other classes as other cultural phenomena do or should a solution, whether reducing, reusing, or recycling, target the majority straight?

5:27 AM

Perhaps both are possible depending on ones plan, budget, connections...

@Jannis // Beyond Plastic So have you tried using lindseed oil as an experiment for coating? I saw an Australian designer use it for a lettuce plate. Since I've seen this I have been researching this extensively also It excites my imagination and I have been waiting for the plans for the machine. It now allows me to start with something and then automate to scale. This is my new personal project asap. https://www.indesignlive.com/the-peeps/maddison-ryder-lettuce-eat-waste-challenge (edited)

@Jannis // Beyond Plastic also try xanthum gum as a binder it might dull the smell issue

It seems to me that aluminium foil is greatly under-utilized in disposable products. It's abundant and should be 100% recyclable, with virtually no degradation, right? Just a thought. Also, in case you missed it: A potential new alternative for clear plastic film: https://discordapp.com/channels/586676777334865928/600998730262380545/644635825807556618

@Frederik C (ZA) one thing to point out about it is that it's made out of fish. That can be an important con for some.

Yes, it's obviously less sustainable than plant-based options. But the fish are getting eaten, anyway. So, might as well utilize the resource and waste less.

@Frederik C (ZA) well I had in mind rather ethical reasons but I guess the answer will be same

@Jannis // Beyond Plastic I have started developing the machines,though in India most of the restaurant use plastic containers to deliver food, and this seems to be a perfect alternative But have you though of any design by which we can have a lid on top of the bowl, something similar to the lid we normally have on the Jam bottles ?

@aditya24786 if you are talking about screw-on lids they shoud be possible to produce using injection. I would say even CNC is not needed for mould since the part is round and could be done on a lathe

@Arseniy (PL) I am talking about some kind of a lid above the bowl (which is shown in the video on the precious plastic page) so that the food can be packed for some time and transported one place to other. I believe same machine can be used to make both bowl and lid.

@protohub: thanks for the link! Hadn't known this project before! Oil and wax are definitely a good call and have been on my mind already. as well as all of the natural binders and xanthan gum is a very interesting one for sure! If you want, we could start a collection of our research into the topic of coatings somewhere together! Then we can just keep adding stuff we find or try to the list. I just don’t really know, which place would be the best for it… Do you have an idea?

10:39 AM

@Frederik C (ZA) and @Arseniy (PL): I know marinatex and I think it's a great idea. and I actually think it's pretty nice to see someone using fish scales. I mean, they produce so much waste in that industry, it would be a shame not to use it. Even though of course, it would be better if they didn't kill the fish in the first place

1

10:41 AM

but for things like this, isn't it just important to not rely on industrial waste, but have alternative sources as well? Then you could use the waste, without making the industry last longer than it would without you. If you get what I mean...

10:46 AM

and @aditya24786: amazing to hear you are building machines already!

10:48 AM

we thought about a to-go container and actually worked on one during the development of V4. However, it turned out that the design of the mould and the principle of the container closing mechanism, didn't really work out. So it didn't make it into the download kit after all. Anyways, you can find a photo of it in the article below. Maybe you have an idea on how to do it better

10:49 AM

I think just creating a lid for the bowl shouldn't be a big problem

I've definitely seen and used a rough cardboard or paper pulp version of this before (for leftovers from a restaurant.) But, in the last few years, all I'm seeing is polystyrene. It bothers me a lot. Is there something wrong with cardboard, in principle? So many fast-food chains use it.

Playing devil's advocate, cardboard is less waterproof (can't really leave food for several days in it, it starts absorbing moisture and becomes soggy), appearance could be offputting (styrene boxes kind of signal 'sterile' cleanliness while dark spotted uneven cardboard with pieces of unprocessed fiber sticking out looks ... less sterile)

3:51 PM

But probably it's just polystyrene being cheaper :D

But probably it's just polystyrene being cheaper Has to be another reason. Virtually every fast-food chain uses something like this:

Good question. I think the little devil up there might have already covered a few possible reasons. As far as I know, cardboard or paper pulp is absorbing liquid and fats too quickly, so they can't really be used for cups or things like this. Even though they might work for shot cups or things like this, that only have to hold the fluid for seconds

3:58 PM

almost all of the cardboard containers I know of that look like the one you posted are lined with plastic on the inside

4:00 PM

that's so they can hold hot moist things and I'd also guess, that it's would change something about the kind of cardboard you could use for food containers, if it wouldn't have a lining

On the upside, i don't remember seeing much of advertisment/branding prints done on styrene boxes while it's easy to do on cardboard ones - that could be additional offer for clients

just think about the ink and stuff you have in recycled paper. I don't think it would be the best idea to put your food inside of that

4:02 PM

but on a bright side: I read about more and more places banning styrofoam containers completely. At least in the US there seems to be a movement towards it. So that's cool.

4:03 PM

plus there are containers from things like sugar cane pulp, which seem to compost very well.

@Jannis // Beyond Plastic btw just found your page about mealworms recycling styrofoam. Do you still think it's a viable idea to recycle large volumes of styrofoam?

4:07 PM

Thinking about ordering some and testing

@Arseniy (PL) it definitely works (I still have them munching away next to me right now

)

4:09 PM

but it's a slow process and right now it's definitely more of a concept still. However I developed the material from the dead beetles a bit further in the last months, so this part is developing.

What's bothering me a bit is that once larvae turn into beetles you have to ... kill them?

haha

4:11 PM

noooo

Or create an insectarium where they roam until they die?

you let them live until they die

4:12 PM

it's actually an important part, because they will make love and make the next generation of worms

4:12 PM

before they die

Right

but yeah, get started and I'm happy to help you throughout the process!

Cool! I'll pm you with some questions then a bit later :)

1

advertisment/branding prints [...] it's easy to do on cardboard ones - that could be additional offer for clients Sounds plausible. Might make it "worth it" to spend a few extra cents (or fraction of a cent) on that type of box.

I've tried asking questions about supply chains at businesses. They tend to say: "Sorry. Trade secrets."

@Jannis // Beyond Plastic I'm up for collaboration for sure! what if we start a dropbox and then publish any results monthly on a new discord channel ( its just an idea.)

Sounds like a good idea. Just need to figure out where my Dropbox is;) Maybe we can share the results here? So that everyone can read them and “add their mustard to it” as we like to say in german

‍♂️

@Jannis // Beyond Plastic here is fine!, I like mustard

@Frederik C (ZA) @Steve Soldwedel - Bronx Just read your conversation about expanded polystyrene EPS egg boxes. Thought I'd move it here for to change tack slightly. Don't underestimate consumer pressure. I ran a campaign on Twitter called 500yearpizza. It took 18months, but we successfully forced Pizzaexpress to switch from EPS to cardboard...

1

2

8:37 AM

We held them to account everytime they published a half truth or fobbed-off consumer complaints about their use of non-recyclable packaging.

8:39 AM

Forcing one brand to make a change is quite different to forcing an entire industry...but maybe there is lower hanging fruit that you can target in to making a move away from plastic?

I'm definitely interested in applying some pressure, @lechatblanc. One big issue, in my case, is that much of the PS cartons are off-brand eggs, and stamped with the grocery store's name. There is one other brand with PS cartons called Mitlitzky's (at least I think that's the spelling). All the rest are PET, and a lot of them are also bootleg brands. The most recognizable brand I've seen is Land-o-Lakes.

Did anyone work on Hexagonal funnel to build solar oven?

I'm sure we've got farms closer than from wherever these eggs come from, but there's nothing local on offer at any of the groceries in my neighborhood because they're all chain stores.

11:50 AM

(pardon the redundant "from"; syntax failure)

@Steve Soldwedel - Bronx yeah, I can see that own brands will be fairly immune to consumer pressure. A premium brand with a sizeable social media following is an ideal target.

12:08 PM

@Steve Soldwedel - Bronx Interesting that you're talking about expensive chicken eggs in EPS. Feeding meal worms EPS, then feeding them to hens seems like a fun circular economy/art project.

1

@lechatblanc, it certainly highlights the absurdity of it all.

Where do they get the bootleg chickens?

We need a How To on this mealworm farming idea on the community website. It sounded like a "loopy" idea to me months ago. But I'm starting to see the potential.

1

@Frederik C (ZA) Yop.. it's quite interesting.. you could use them to feed birds, to feed fishes (even bigger ones like saloms in aquafarms) or use it in order to get some proteins

1

5:58 PM

I've been told that they do not have a strength taste.. but roasted they should taste .. like chips. I did not taste it ..

Yeah, they don’t taste like much. Kind of nutty and a little like wheat sometimes. Stanford also released another study some in December where they tested them for remains again. And didn’t find anything after they fully digested the styrofoam. Plus they tested their reactions to styrofoam with additives like the flame retardants that are often added for house insulation. It didn’t make any difference to them. I mean, there have been studies on this some years ago already, but I guess a study by Stanford always helps;)

3

8:05 PM

And @Frederik C (ZA) would you like a How-to on PP? I don’t actually know if it fits there or if it would open the spectrum a little to far. Even though... I guess it’s still about plastic;)

8:07 PM

I’m also starting to create a rough concept for a community based platform for biodegradable materials right now, since I feel like there are so many good people and projects out there, but they are very scattered and don’t really build on top of each other’s research and we could be so much stronger if we would have a place to actually work together.

8:10 PM

I’m trying to come up with a concept so that the conceptual, building and running process is as open and community driven as possible, so if and of you have examples, an opinion or input on it, I’d be super happy to hear it

8:11 PM

I’ll also post a more defined outline of it here in a few weeks, when I got it more figured out

8:13 PM

Oh and @lechatblanc super cool!

I’d be super interested in hearing more about the tactics you used in order to put pressure on them. It’s something that always seems like magic to me, when someone actually figures out how to push the right buttons in something like this!

1

would you like a How-to on PP? I don’t actually know if it fits there or if it would open the spectrum a little to far. Even though... I guess it’s still about plastic;)

@Jannis // Beyond Plastic Definitely. People are asking about EPS, all the time. It's one of the least recycled plastic products. My municipality also doesn't accept it. And PP HQ still has no recommended solution (though, as I pointed out, not for a lack of trying.)

Good point!

@Jannis // Beyond Plastic Maybe I should write a blog post on it? Here's a summary in bullet points. 1. Get cross and write to them. 2. Research what other brands are doing in the same sector. 3. Find out who owns the company, get a copy of the annual reports. 4. Which supermarkets list the products? 5. Use sales figures from annual report to estimate scale of problem. 6. Create Twitter profile and hashtag. 7. Follow-like minded Twitter accounts and hastags. 8. Search the Twitter feed of the brand for people complaining about the issue. 9. Reply to complainers and say you are campaigning. Alert them to the fact that Xyears have passed since they complained. 10. Retweet and like their reaction. 11. Find historic tweets from brand and highlight shallow message from X years ago. Screenshot these tweets as they WILL delete them. 12. Encourage complainers to use other brands and @ the supermarkets to show them they are losing sales. 13. Keep going. Search variations of 'Packaging', 'Plastic', 'Waste', 'Recycle' etc in their twitter feed. If you can reply to complaints before they do, you really have them on the back foot. TIPS: Use your hashtag and those of other campaigners on all your tweets. Their annual report will be full of great boasts about volumes and profit. Use their language against them.

Also, have anonymous, silent "sleeper accounts" just to observe your "prey." Because anyone associated with the campaign will probably get blocked.

My comments might seem weird, but in my country, whistleblowers and activists don't go to prison (like in the US and EU). They literally disappear off the face of the Earth. Never to be seen again. And political assassination is like a national hobby. And we actually have tried to sue US companies who profited from virtual slave labour in South Africa (SA), in US courts. Those companies all bought their way out of it. The cases were thrown out of court because of "jurisdiction" bullcrap. A few years later, UK intelligence were caught bugging human rights lawyers' offices in SA. The spider-web of multi-national corporations, knows no bounds. "Just because you're paranoid, doesn't mean they're not out to get you." So, in that sense, the smaller players (the "low-hanging fruit") might be better to target. But you never know how connected they actually are.

@shreyas it's a stiff spring so that when the plastic melts and gets squashed the force remains consistent. Without a spring the melted plastic would compress and a user would have to manually re-tighten the press.

@shreyas I thunk we also explain it in the how to build video, but anyways... the springs keep the hot Aluminium block elevated from the metal box around it, so that it’s insulated by the air around it. I spend a lot of time researching into different forms of insulation for this, since it turned out to be quite challenging to find an insulation that can withstand the pressure we use.

Related to edibility (sort of): I'm curious about the expected shelf-life of the containers. (Maybe that's in the new video. I still have to watch that... along with several others

Any possibilities for using hemp products for containers? South Africa is on the road to legalized hemp cultivation. Private consumption of marijuana was legalized in 2018. (That tends to be the first step towards commercial hemp production, I think.)

Fair point. I don't want to go crazy obsessive about things as if my stopping using artificial sponges is somehow going to save humanity from itself. I know that nearly nothing I do on an individual level makes any difference on a global scale (probably not even on a local scale), but I'm trying to avoid doing things that I can do that are helpful to the environment and that mitigate plastic consumption, whether it's futile or not.

@Jannis // Beyond Plastic Hey Jannis can you explain to me the mechanisms that hold the materials together? Im trying to understand ... is it heat & pressure or a binder or both? or something else?

@Steve Soldwedel - Bronx & @ninja: I basically used loofa sponges all year to clean the moulds and I think they worked quite alright. I didn't use them exclusively, since they don't have such a strong scrub and they also don't last as long as the plastic ones, but still. I like them

9:58 AM

and what I also just realized I never tried, but always do with the plastic ones is putting them in the washing machine when they are all clogged with grease. I'll give it a try and let you know how it works!

10:02 AM

@aditya24786 the only material we labeled as edible is the wheat bran one, since we got the material itself already as foodsafe. With the other materials it probably depends a lot on where your material comes from and what it looks like exactly. Organic orange peels might be okay to eat, non-organic ones might have a lot of pesticide pollution, so maybe not the best to eat

10:03 AM

plus, it also depends on how you dry them and store them

10:10 AM

And @lechatblanc: So the mechanisms of how the materials hold together vary a bit. All of the materials bind because of the compression. The cellulose ones, like the coffee ground sheets for example hold because they are compressed and heated at the same time, which does something to the cellulose parts in it that makes them bind again. And in other materials like the wheat bran, the stale bread or the potato peels it's starch, that acts as a natural binder. The moist starch starts gelatinizing at around 60°C and then works as a kind of glue that hardens when it cools down. Which is pretty useful, when for some reason you can't get your material compressed, your mould doesn't close properly or you don't have enough pressure for any other reason... Because then the material hardens a lot more after pressing.

10:15 AM

And other materials like the orange peels have a wild mix of ingredients inside of them, which work as binders and bind with pressure: Cellulose, pectin, starch, oils...

@Jannis // Beyond Plastic I actually put my sponge in a plastic container in my fridge when I'm not using it, and if it gets musty, I'll put it in boiling water for a spell. I get a lot of life out of my artificial sponges. (edited)

10:22 PM

@aditya24786 this may be a good place to look for potential materials

As for packing material alternatives to EPS, there is one: https://www.intelligentliving.co/amp/ikea-mushroom-based-packaging • Agricultural byproducts such as hemp, husk, oat hulls, and cotton burrs, are pressed into the desired shape that can fit around items as packaging. • Then, it is seeded with mushroom spores that sprout mycelium (a root structure) after a few days. • The mycelium threads rapidly through the structure and binds it together to form a shock-resistant and durable packaging material. • The last step is to heat-treat the material to kill spores in order to arrest further growth of the fungus. Not only does it fit into the planet’s natural recycling system efficiently, but it is also cost-effective to produce and almost as durable as plastic. MycoComposite has also proved to be as insulating and flame-resistant as polystyrene. However, nobody even knew about this brilliant material until furniture giant, IKEA made the mushroom-based packaging mainstream by announcing that it will replace Styrofoam packaging with MycoComposite for all of its products However: Ecovative Design says in their FAQ, that MycoComposite is not water-resistant. So, now I'm starting to think about natural wax coatings to make stuff waterproof.

And as I thought, hemp byproducts are suitable as a base material. That's good news for my country. The main problem I see here, besides the water-resistance issue, is to streamline the production rate to be able to match the output of EPS factories.

2:52 AM

From their material spec sheet:

2:55 AM

They say MycoComposite decomposes in 30 days when it gets wet.

Maybe look into Appeal in Santa Barbara, they work with a natural coating on fruits and vegetables that is resistant to oxidation. I assume it also has some water resistant properties to it.

@Frederik C (ZA) what you said about rate of production - seems very hard to scale

8:14 AM

I wonder if it's possible to just press base material with some binder. Obviously, finding the binder is the hard part.

For it to have the shock-absorbing qualities of EPS, yes. The materials Jannis has used seem to bind just fine. But they are no good as buffer material. Maybe something like what is used to make chip-foam sheets. That's made from PE and PU offcuts from foam factories. (Used in mattresses and gymnastics mats.)

The thing is: Exact form molds are "fancy" and look nice, but are not technically necessary. Filling a box with pellets / "peanuts" is fine. And if you can make reasonably sized sheets (similar to V4 sheet-press) and have a CNC cutter, you can make all kinds of box templates that can be shipped as a flat pack. (Like pizza boxes.)

@Frederik C (ZA) agree about 'beans' in packaging. Nevertheless quite often a somewhat rigid protection for corners is required for them to not be smashed.

9:31 AM

So, of PS is expanded to create EPS maybe it's possible to expand a non-plastic material.

It's expanded by a chemical process, that produces a CO2 froth. The bubbles are then slowly filled with air as the CO2 leaks out. (I think. That's how it works with PU.) (edited)

Hmm, can yeast be used?

packing peanuts

9:43 AM

the one with more of a shape (bottom right) tend to be 'crunchier' and leave the debris i mentioned

Also, should be less static with natural material.

going to be looking into honeycomb board soon, see if it's cheap enough to use for packing in place of foam

To be fair, most packing chips we see in the UK now are made potato starch. They dissolve in water, but they're still an awkward pain.

To be fair, most packing chips we see in the UK now are made potato starch. They dissolve in water And form-fitting moulding is probably a problem for the manufacturers... for all the same reasons we are discussing.

While talking about packaging, what are thoughts about bubble wrap?

Dyson shipped a vacuum to us with zero plastic packaging. The box had well designed folded cardboard inserts. Google and various other good quality tech brands use a re-formed cardboard (Like a fine-grained cardboard egg carton).

Seems like an obvious approach, when you think about it. Industries so often get stuck in a mindset. (edited)

nothing beats bubble wrap in doing what bubble wrap does

looks more difficult to handle the moment it comes out of a box

I can understand that with electronics, in particular, vibrations in shipping are a bigger concern. (edited)

bubble is just so cheap and easy to handle

Everything with plastics is "too easy." That's why it was the "miracle material" of the 20th Century... and we have our whole dilemma with it.

Just to confirm, bubble wrap alternative for packaging doesn't need to be transparent, right?

10:26 AM

Because I've seen it used in greenhouses as insulation where it does need to allow light in

Just to confirm, bubble wrap alternative for packaging doesn't need to be transparent, right? I guess it doesn't matter.

I can't think of why it would be necessary.

@Arseniy (PL): can yeast be used? Interesting idea. Worth looking into. However, using non-edible, agricultural byproducts, is preferable, since it would otherwise go to waste. Hemp is sort of in between. Easier to grow and down-scale than the conventional sources of cardboard. Uses a lot less fresh water too. (Water scarcity is a major problem now, in many parts of the World. For me too.) I'm not sure what kind of plastic bubble wrap is made of. I'm assuming it's "recyclable" in the same sense as most packaging. There seems to be an industry move towards better practice, by making bubble-wrap more durable, for re-use. So the plastic is thicker and tougher, so the bubbles don't pop. But still, how much bubble wrap can you horde in your house, before you have to take it somewhere? (edited)

Hi everyone! I'm Dave, a faculty at Parsons School of Design. I organize the Precious Plastic Parsons workspace and I'm part of the Precious Plastic NYC group. https://www.instagram.com/explore/tags/preciousplasticparsons/ https://www.instagram.com/preciousplasticnyc/ I’m teaching a course this semester working with biodegradable materials from food waste and using Beyond Plastic as an entry point. The plan is to fabricate a basic press and experiment with recipes from the Beyond Plastic material book and recipes from the Materiom website. We have a plethora of coffee shops and juice bars in the neighborhood that we’re looking to partner with for a material resource. As first steps we’re purchasing a dehydrator and toaster oven for drying the materials. I’ve found instructions on using a toaster oven to dry used coffee grounds, all others will use a dehydrator. The university always has concerns with safety and in some cases it’s best to purchase equipment rather than DIY builds when working with electrical equipment that is unattended for periods of time. I’d appreciate and specific recommendations on specific brand dehydrators, blenders, and food processors. @Jannis // Beyond Plastic I’d be grateful to discuss some specifics about the press, your previous experience modifying a benchtop press, and dehydration aspects of the project.

Very interesting for beginners, like me: https://en.m.wikipedia.org/wiki/Natural_fiber "The earliest evidence of humans using fibers is the discovery of wool and dyed flax fibers found in a prehistoric cave in the Republic of Georgia that date back to 36,000 BP." Whoaw

(edited)

Anyway, I'm now particularly interested in flax "straw." It's being used as housing insulation and seems that it would have shock-absorbing properties.

@Frederik C (ZA) to maximize the flexibility of a material like MycoComposite the spawn and substrate can be inoculated in bulk. Once the substrate is 60-100% colonized it can be easily broken up (either by agitation or oscillation), then placed into the desired form. From there it takes 2-4 days for the mycelium to consolidate in the form, at which point it can be baked to retain the shape and kill the mycelium. While the colonization time seems like a major stumbling block, the baking is actually a huge energy draw, since colonized substrate is such a good thermal insulator. In projects with long lead times in cold climates dehydration and freeze sterilization is an option, but that's a very rare circumstance, so the process consumes immense heat energy from electric or natural gas heated ovens. On the upside, the heat in the finished product coming out of the oven promotes wicking of water proofing, like waxes or oils.

Yeah, in terms of output (and serious consideration as a replacement for EPS) anything that can be easily cultivated in a vertical farming / greenhouse environment, has a clear advantage. Flax seems to be a bit finicky about growing well in certain places.

For a loose fill there's always starched blown cellulose. There's waste paper everywhere, and short fiber pulp is usually incinerated. It works well on its own, but it can also be used as substrate for mycocomposite, particularly where high part resolution is desired.

Custom cardboard inserts, made in the same factories that make the shipping boxes seems like the simplest solution. As always, the problem begins with figuring out corporate psychology. They already can do it. Why don't they?

⁉

Die cost/space/inventory/tooling is a major concern. Smaller pieces don't ship very well, so perforated in stock is a more realistic solution, but that also means they're shipping waste to their customers, who have to employ manual labor to break the stock down, as well as insert it correctly, and also deal with the waste stream. There are plenty of "whys" at hand.

There are plenty of "whys" at hand. ... ....for why the human race is doomed.

Popular outcry is the most effective method of pushing production away from profitability and towards sustainability. The most effective counter to it from the corporate side is "we can't", but if it's demonstrated to the public that "they can", the argument collapses.

https://www.dezeen.com/2018/11/01/don-kwaning-makes-furniture-packaging-from-wetland-weed/ Don Kwaning makes furniture and packaging from a wetland weed – 1 November 2018 Design Academy Eindhoven graduate Don Kwaning has created an ecological packaging material from the pith of a fast growing plant called soft rush – a weed, which grows in tufts in wetland habitats like wet woodlands, marshes, ditches and grasslands. Through his Medulla project, Kwaning sought to find new applications for soft rush, by separating the pith from the fibres. Each year in the Netherlands state forestry removes thousands of kilos of the plant, which is then fermented and turned into biogas. Alternatively the fibres are used to improve the structure of agricultural soil that contains a lot of sand. Kwaning's research found that the fibres can be developed into materials like paper, corrugated cardboard, rope, non-wovens and textiles, while the pith of the soft rush can be used as a foam material. The pith's lightweight, shock-resistant and insulating properties make it suitable for use as an ecological packaging material that can be applied as tangled noodle strings or as compressed foam blocks. The foamy pith doesn't require any bonding additives can be compressed in different densities, which makes it suitable for use as a lightweight sheet material that can be applied in furniture production. Kwaning has demonstrated the plant's various uses by using the material to create a noodle-like packing material, packaging papers made from the soft rush fibres, two packaging boxes and a set of five storage boxes that double as a side table.

Has anyone in this Beyond Plastic community sold their products? What would a bowl or a cup sell for? I’m going to get a machine built to start experimenting with food waste materials this coming summer but I’m just curious with how these products would be priced / sold?

2

Has anyone in this Beyond Plastic community sold their products? Probably not. It's in the "Research" section of the PP website, because it's still highly experimental. And if the products do become ready for market, you've got the up-hill battle of fighting the multi-billion $ plastics industry, directly. They will not just roll over and die. (As the video and previous articles I and others have posted, hopefully demonstrates.) But, ultimately, it's about giving consumers and companies alternative options. The rest is up to them.

@lechatblanc Thanks for posting https://discordapp.com/channels/586676777334865928/605686860324536320/679444783093121054 I was curious about the so-called "Green Alliance" based on the statement:

Green Alliance's Plastic Promises report, which warned against the consequences of demonizing plastic and rushing to find alternatives, 'to avoid the risk of simply substituting current environmental problems with new ones'

From their website: "Green Alliance is an independent think tank and charity focused on ambitious leadership for the environment. Since 1979, we have been working with the most influential leaders in business, NGOs and politics to accelerate political action and create transformative policy for a green and prosperous UK." Yeah...Riiiigghtt

Have they considered that maybe... they suck at what they do and should pursue other careers?

@Frederik C (ZA) Everytime a think tank is named something like "green alliance" or "For the truth" or "Union for free speech", they usually do exactly the reverse. For example something like "For the truth about Earth" would be a flat-earth lobby. "For the workers and people" would be some multi-billionaire 'how to enslave your workers' lobby. They try to get legitimacy by using a name that sound right, but actually isn't, so they can 'infiltrate' the debate.

"Think tank" is very appropriate. Because their thinking "tanks." And good ideas tend to be accumulated and stored away where no-one can see them. I'm often not capable of telling the difference between stupidity and malice. So, I tend to err on the side of caution, and invoke Hanlon's Razor: "Never attribute to malice, that which is adequately explained by stupidity." (a.k.a. "Cock-up before conspiracy.") I think it's a Dunning-Kruger Effect kind of thing. (edited)

Japanese company turning the tables on plastic waste

In the future, when someone implores a dining companion to "finish off the meal," it just might mean that they are expected to eat the plate and cutlery, too

It's always a bit weird to me that so many people are willing to eat fast food with their hands, after handling money and wallets. I tend to use disinfectant wet-wipes that I carry in my pocket. But most take-away places don't offer hand-washing stations next to the counter. Also, place-mats are needed if they expect people to put the bowls on public tables. Then again, just because the bowl is edible, doesn't mean you have to eat it. Most people probably won't. It's still biodegradable. That's the main thing. Whether or not company logos can be clearly printed on it, with edible inks, is the second big factor. We have theorized before that this might be the main reason most franchises use cardboard containers instead of XPS. Branding opportunity instead of cost. (edited)

How about when you order food and the person wearing gloves to handle the food then takes your money and fishes around for change...wearing the same gloves.

Yeeeaaahhh... if that happens, it's not supposed to. Cashier duty and packing duty are usually separate, whenever I've paid attention. When it's not, the food is already packaged (by kitchen staff.) But that's just it... you don't eat the packaging. And I've mostly seen thin, transparent film "gloves." They are very loose and slip right on and off your hand, quickly. So, they probably go through dozens of pairs per day (in itself a problem.)

Hi, I just came across this article https://www.businessinsider.com/ford-mcdonalds-coffee-bean-chaff-car-parts-2019-12 about Ford using coffee waste mixed with plastic and I would like to know your opinion on this. I think, that coffee waste alone is decomposable, but not mixed with plastic. What about recyclability of the new composite? (edited)

How Ford makes car parts from used McDonald's coffee beans

McDonald's produces more than 62 million pounds of coffee chaff that used to go to landfills. It teamed up with Ford to turn the waste into car parts.

Sounds like a PR gimmick to me. Also, it's still petroleum-based plastic, with all the problems that come with it. #archived-beyond-plastic is about finding alternatives for single-use petroleum-based / non-bio-accumulating plastic. Because recycling is unlikely to ever outstrip the production rate and demand.

The oil industry literally has "game plans" that span 70 years or more. That's how rich those bastards are. They can plan almost a century ahead, because they are "untouchable." For example, the plan to suppress climate change awareness, started back in the 80s. What's the plan for the end of oil to petroleum production, around the year 2075? Who knows? (I have some theories.) Information leaks out, now and then, but who knows what they are really planning? I just know it probably isn't pretty. From years ago, Royal Dutch Shell has (or had) a scenario called "Scramble." It's basically World War 3, to "reposition" the entire global economy for the "transition" to... who knows what? (edited)

Has anyone else besides the Precious Plastic team built the biopress? Looking to get it fabricated to start experimenting with. I’m in Canada and have a couple companies getting quotes together but would like to see if there are any other options from community members.

Do any of you know companies that recycle solar panels and wind turbines?

6:34 PM

Also, what is your take on atomic energy?

https://calculator.greenpolymer.in/ Built this simple app that estimates your recycle foot print. Any place I can find plastic specific data (PP, HDPE, LDPE etc)?

Recyculator|Green Polymer

Calculate your recycle footprint

@Uplifted I don't know about solar panels, but wind turbines are thermoset. Quote from the academy: "Thermoset plastics contain polymers that cross-link together and create an irreversible bond, meaning they can’t be melted - once they take shape, they will be solidified forever. Think of Thermoset as bread: once bread is made, if you try to heat it, it just burns. None of these plastics can be recycled."

4:26 AM

In my opinion, it is nearly impossible to stop using atomic energy for at least next century. They only can change the percentage and stop building new ones... which they should. Also, more safety.

Interesting you said that about the turbines. https://youtu.be/pKE6CdEkAQY

Oh I get the method.

4:31 AM

I think that's the only way they can recycle thermosets.

4:33 AM

Sounds good.

1

What is your take on atomic energy?

From what I've been hearing. It let's out less carbon emissions plus more energy. While solar energy and wind energy is good, it gives off more waste, mostly because they last 10 to 15 years. Although these wind turbines and solar panels can be recycled in a different way, they don't get recycled enough unfortunately.

4:41 AM

Again this is what I've been hearing through the grape vine.

I think they last more?

4:41 AM

Not sure tho

4:44 AM

4:58 AM

In Japan, 28% is ok with Nuclear Plants and 59% is not ok. It's mostly because of the accident.

In Fukushima I presume?

Yes

5:03 AM

Almost everyone I know has changed their mind after that accident.

5:03 AM

It's a difficult question

My opinion, best thing is to distribute power methods strategically. Where atom power is needed. Put atom power. Where wind and solar are needed. Put wind and solar. Where diesel power can be pushed without doing as great a damage. Put it there. So on, so forth.

1

I remember there was a young man who created a atomic generator in his garage. He was considered a genius, visited by president Barack Obama. He intended to get into the Atomic power plant business. His plan on how to make it safer was simple, he would bury the generator underground. If it ruptures it would only sink deeper into the ground, thus in theory, be contained. Once it sat there underground for some hundreds of years, it would crystallize and turn into a mineral. (edited)

6:31 AM

I saw this and just had so many questions.

What if it harms underground wild life?

This channel is now way off-topic. I'm not a moderator, but just saying.

Yeah, you're right. Sorry about that.

@Nicolas Lamoureux (PPYQG) I'm gonna build a biopress in the next month or so. i've bought a manual bottle jack and found a used rated hydraulic press frame. it feels way safer for me to know that i'm going to use a rated frame when applying something like 20 tons to a frame (could blow the top part through the roof if underbuilt). If you want to build the frame, I would consider joining the frame with graded bolts, will be easier to make sure your frame is rated for your working pressure rather than welds.

1

@AlexandreS Are you by chance located in North America haha? That’s great advice though. I’m unfortunately not skilled enough mechanically to build this so I was looking to get it fabricated. I have a friend that runs a collection / composting business and the area I live in is very much agricultural so I was hoping to take this waste and start experimenting but I’m limited in my mechanical / technical abilities. Thanks for the reply though! I’ll do some more research and maybe I can build something from already made components. (edited)

@Nicolas Lamoureux (PPYQG) Yeah I am in Québec, Canada ! I'd say you could try to find an old press or frame, it will probably be cheaper than pay a welder to build the whole thing (Although the design of the press made by Jannis is really cool and well packaged). From there you could try to build the rest or pay a guy to finish it

2

@AlexandreS No way! Cool! All my dad’s side of my family lives in and around Longueuil. Let me know how your press goes as it progresses. I’m trying to find someone near me to help fabricate it but I’m finding it difficult or incredibly expensive. Thank you!

@Housane That’s a good question. I’m not too sure whether this could get to the temperatures needed for melting PLA. Something to look into. Maybe someone else in here can answer that. (edited)

Sorry for trolling but PLA is not really the best go for polymer as it needs to be treated in specific high temperature composters. I find plenty on the beach. Go biodegradable!

A lot of that problem is people being dumb and not disposing of plastic properly. Granted i am young, dumb, and idealistic, but perhaps with grassroots education movements, as well as economic incentives (pay to recycle, nothing to litter), we can stop the core problem.

didn't say what the mystery plastic was, assuming PLA or cellulose acetate?

1:50 AM

mentions of sugar are making me think pla?

Many unanswered questions in the article. Part of the problem is the ambiguity of the term "degradable." Like those shopping bags that "degrade" into microplastic, after a year. Doesn't help the environment, at all. Recycling and production energy budget also has to be accounted for. Not to mention the carbon footprint. The initial source of the material is only a small piece of the puzzle. Replacing one set of environmental deficits, with another equally bad set, doesn't really solve anything. In my opinion, a fossil-based plastic that breaks down with minimal energy investment, has few waste products and has multiple life-cycles, is potentially better than what they propose. After all, when the planet's oil runs out in about 50 years (assuming humans survive that long) they will just switch to coal as the main source. (edited)

another important thing on peak oil, there may be a PILE of reserves but most is hard to get

2:23 PM

and it gets worse over time

so there MAY be long term oil, but it gets more and more expensive

I will check it out!

Just a reminder that the channel is about plastic packaging alternatives. Also the PP community is generally opposed to pyrolysis as a wholesale solution to plastic waste. But there are some forum threads on the topic. It might have some utility in some limited circumstances. But it's not a popular solution in PP. And I agree.

I agree recycling is better, but for thermosets etc, nothing else can be used. Also a scrubber etc WOULD be needed. Better than microplastics IMO. I will stop discussing it here.

1

There have been some hints of new recyclable thermosets in recent years, as you probably know. The general lack of publicity on it, makes me think the researchers might be onto something, that the oil industry really won't like. Especially since the discoveries tend to happen by accident. (No money in sustained research.) But yes, then there's still the tons of the old kind still lying around.

I think less so coverup (saw all sorts of news on it), i bet it is more change being slow, and old stuff not being phased out yet (tooling etc)

Yes, the electric car has been around over 100 years. The best way to "kill" an unwanted technology is not by "suppressing" it per se, but by allowing it to "die" and fade from memory. Otherwise you create a Streisand Effect.

Hello people! Has anyone here done any durable material with used coffee grounds? I've read on the internet that you can combine it with other renewable materials and with the inyector or the press you can make something that can last for years. I will start investigatin and experimenting at home, but if anyone has information if would be very useful

I seem to remember coffee being in Jannis' original project. Wasn't it?

compostables was mentioned in the v4 video towards the end.

8:27 AM

also, in my personal research around other sustainable materials, i found it's quite easy to recycle and compose cardboard from mulch to product

Recycle Cardboard into Anything with 3D Printing!

8:27 AM

it's really quite easy to go from cardboard > mulch (combine with other fibers or materials at this stage) + 3d printed mold > product

8:28 AM

curious if @davehakkens has seen things like this, and if they're on the roadmap to be incorporated for pp

I’ve been thinking a lot about single-use items and about what that does to our perception of their value. Should we be creating things that are single-use at all even if they are “eco-friendly”? If you could imagine a scenario where every single-use plastic item was replaced with a compostable / biodegradable alternative would this be good for the environment? I’m not trying to dissuade research into this project, I’m actively looking into getting a biopress myself, but I think these are important questions to think about. Can we imagine a future where the concept of single-use doesn’t exist?

Yes, we can. But... humans.

Just doesn't work well with our profit first economy system.

Actually, it's the convenience factor. The consumers don't want to think about anything hygiene related, for more than 30 seconds. The suppliers make more money in the long run. The franchises have one less supply chain to manage. And, first and foremost: "But we've been doing it like this for 70 years... It's working just fine"

(The fact that the World population has doubled in those 70 years is apparently not part of the equation.)

1

It's part of Neo-Classical Economics. Neo-Classical Economics functions in a Universe where the Earth somehow has unlimited space and resources. It must be true, though. Why else would they teach it at prestigious universities?

(edited)

Are there anything infinite in this real world?

I don't know. Einstein once wrote a letter critique on some cosmological proof to an academic rival (I forget who) that said: "Your Mathematics is good, but your Physics is atrocious." Psychological compartmentalization, I guess.

8:50 AM

[Is] there anything infinite Short answer: Based on the Second Law of Thermodynamics: No. Except perhaps the space-time fabric itself.

Also, I looked it up: The comment was directed at George Lemaître concerning the Big Bang theory. So, by disagreeing, Einstein was ironically wrong. He was wrong about a lot of things. But the rule of thumb remains intact nonetheless, I think.

Huh I remember laws of thermodynamics a bit

9:13 AM

System in the universe degrade or disorder? Was that it I guess

9:15 AM

How was our universe made?

9:16 AM

System needs to start otherwise the universe is infinite years old???

Read Stephen Hawking and Lawrence Krauss. I read that Einstein story in one of Krauss' books. We've gone from "beyond plastic" to "beyond space-time."

It's still beyond plastic

just too far

Hi all, We are starting a housing development plan using recycled plastic to make the bricks with. I would like to know what to mix with the plastic to make it fireproof? Can anyone help with this maybe? (edited)

9:30 AM

This project will create many jobs as we plan to train and educate as we go. Will also assist others to open their own small companies to create furniture, roof tiles, paving etc

1

@Noeline This is actually the wrong channel. If you can get hold of one of those commercial bricks at Builders, it can be analyzed. I doubt that they will willingly divulge their "trade secrets," but the SA community can investigate. In other African countries, as far as I know, they only add river sand.

@ Frederick. Thank you. Will do

@Frederik C (ZA) some use people's stupidity for their good

@Frederik C (ZA) Couldn’t the “convenience factor” be weened through by negative reinforcement? For example, in Storm Water Management Design for site plans every new building built needs to control and manage the water that is dispersed onto the site. Couldn’t we do this with garbage too? If people want to buy single-use items then they need to manage them on-site themselves. If they don’t want to then the alternative shouldn’t be a “free” garbage collection that allows your conscious to be absolved every week by removing these items from your life. This also works with the “profit first economy system” @Lazy_Turtle. The only reason this is profitable is because the companies producing these single-use products don’t need to carry it through for their whole lifecycle. If companies had to properly dispose of or manage their single-use items then maybe it would be more profitable to make longer lasting items. (edited)

The only way I can see a plastic alternative working for a single-use purpose would be if the item wasn’t really “single-use” and it had a secondary function. If something is biodegradable then that’s great but what are we doing with all of the biodegraded material. Does this all get used on site or does it become fertilizer for farmers? Does the energy needed to make one single-use item have enough of a kick-back through its secondary use to make this a successful project? Or should we be aiming to eliminate single-use items entirely? Only create items that have longevity and multiple uses that outweigh the energy put into the system to create the object in the first place. (edited)

1

Most us can speculate about changing the system. But it's completely irrelevant. It can only be enforced through legislation. Legislation is controlled by the highest bidder. You're not taking about changing a mindset. You're talking about changing how politics works.

@Frederik C (ZA) Well you might think it’s completely irrelevant but I certainly do not. How do you think changes are made besides someone at some point making speculations? Legislation is not always controlled by the highest bidder and even if this was the case, our collective dollars are worth more than what the highest bidder has. If we stopped buying single-use items, producers would stop making them. I am talking about changing a mindset and changing how politics works and changing how we value objects. That’s literally what PP is all about.

5:05 PM

And going “beyond-plastic” is mostly speculative anyways. If you don’t think change is possible then what are you doing here?

Hi everyone! Has anyone tried to use cellulose acetate with the injection machine? I am new here, and i can't find (free) information about bioplastics recycling.

Open Source Ecology is doing work on paper waste/cellulositic biomass -> cellulose acetate https://wiki.opensourceecology.org/wiki/Cellulose_acetate i'd say we are 1/3-1/2 through the dev process (ie past conceptual dev, but pre prototype/cad/sims) (edited)

Cellulose acetate

Bravo! thank you

feel free to join as a developer/device tester...

as soon as i gets some results i will definitely share

make an ose wiki account if you want too!

I have seem some paper about making fuel with plastic through hydrolysis at 25mpa... however I'm too fond about the fuel part, is there way to transform fuel into something eco friendly instead of burning it back?

depends on your capabilities really

3:46 AM

if you have a LOT of tech, you could burn it, absorb and reprocess pollutants and use co2 in a greenhouse

3:46 AM

i think the route for that would be washed plastic->pyrolysis->fractional distillation->petrochemistry

3:46 AM

doable, but difficult

3:47 AM

i find washed plastic->pyrolysis->some burning cycle with emmisions control

3:47 AM

i would love that paper though!

Hydrolysis not pyrolysis

both work

3:47 AM

was it HTL?

3:47 AM

i know that works with algae

Wait i try to find back the article

3:49 AM

But generally i just want to rid of any fuel by transforming it

3:50 AM

A lot of research end with producing fuel

that will involve, biocrude handling (potential spills), petrochemistry (potential spills + waste products), then plastic production, then forming (energy in)

3:51 AM

i think a low nox+soot burner, then an automotive post processing setup would be way better ecologically wise

I understand nothing of the jargon herelol

no that's fine lol 2/3 of my speach these days is jargon

3:52 AM

i can grab a good wikipedia page or 2

3:53 AM

so you would use this for post processing, with enough work: https://en.wikipedia.org/wiki/Catalytic_converter

Catalytic converter

A catalytic converter is an exhaust emission control device that reduces toxic gases and pollutants in exhaust gas from an internal combustion engine into less-toxic pollutants by catalyzing a redox reaction (an oxidation and a reduction reaction). Catalytic converters are usu...

3:53 AM

so pyrolyser makes gas, and liquid, these get burned in some sort of engine, that spits out mostly co2 and water, can scrub off what isn't

3:54 AM

also could use this type of thing TOO as it would be stationary:

I precisely want to avoid any burning

what i am saying is other methods will hurt the enviroment more

3:54 AM

also you can do carbon seperation and capture if need be

3:54 AM

the issue is scale mainly

3:55 AM

amine scrubbing is intense

3:55 AM

charcoal may be doable?

Amine?

long rant, essentially a liquid that can absorb co2 when at 200c or so and releases it at ambient

3:55 AM

like a heat pump but for co2

3:55 AM

then gas is put in storage

3:56 AM

https://en.wikipedia.org/wiki/Amine_gas_treating

Amine gas treating

Amine gas treating, also known as amine scrubbing, gas sweetening and acid gas removal, refers to a group of processes that use aqueous solutions of various alkylamines (commonly referred to simply as amines) to remove hydrogen sulfide (H2S) and carbon dioxide (CO2) from gases...

3:56 AM

https://en.wikipedia.org/wiki/Carbon_capture_and_storage

Carbon capture and storage

Carbon capture and storage (CCS) (or carbon capture and sequestration or carbon control and sequestration) is the process of capturing waste carbon dioxide (CO2) usually from large point sources, such as a cement factory or biomass power plant, transporting it to a storage sit...

So you say depolymerisation using water

3:56 AM

To produce fuel

i am unsure on that, pyrolysis is easy, hydrolysis for plastics is new to me

3:57 AM

then use fuel in an eco friendly burner (ie no* emissions just co2 and water)

3:57 AM

or charcoal

3:57 AM

also co2 is very useful in greenhouses

I'm specifically asking for the hydrolysis since the plastic is getting broke and recombine with water molecule without producing gas

3:58 AM

Anyway

https://wiki.opensourceecology.org/wiki/CO2_Enrichment

CO2 Enrichment

I wasn't asking about the process

3:58 AM

Just the end result

3:59 AM

Once we get the fuel

i would love the paper, as hydrolysis is used for biomass, i am just nott aware yet on plastic

What can we do to transform it aside burning it

3:59 AM

For example can we turn into sugar?

methane->methanocite->cell lysis media->yeast->distiller->ethanol+methanol MAY be doable that or methane->methanol / ?

4:01 AM

sugar seems hard, and that would still "emit" co2 eventually

4:01 AM

also would involve more liquid hazerdous waste

The hydrolysis method can be find on google using key word plastic turned into jet fuel

4:05 AM

It turn pet into intermediate dimethyl terephthalate

4:05 AM

ah

4:06 AM

pet does hydrolyse easily ~~actually what makes it hard to recycle~~

4:06 AM

if even a little water is in it and it heats, it falls apart

4:06 AM

that won't work for any* (double check me) other plastic

Actually isn't this the wrong channel?

not entirely

4:07 AM

pp is somewhat anti this, but honestly it is important for un-recyclable plastic

4:07 AM

and it CAN be done in a safe and eco friendly manner, just needs work

PP just focuses on upcycling, so maybe there should be a new channel

4:08 AM

Am I right about this?

they were removing channels soooooooooo

4:08 AM

although i do overorganize at times

I think there is a potential, but when possible upcycling is better

definetly

I am not a machine guy btw

I'm going to look into pyrolysis too, I'm actually looking for slow tech kinda

but foamed polystyrene, thermosets, old damaged plastics, microplastic's from a filter could all be disposed of this way

4:10 AM

and generate energy

4:11 AM

for machines recycling other plastic

4:11 AM

the scrubbing is the hard part, pyrolyis can be done with a paint can and wood bonfire

If it can be made with off the shelf trash, then left alone to turn into something useful (edited)

4:12 AM

Like using plain solar ray foocusing heat input (edited)

Just remember, the goal is to reduce plastic waste, not producing stuff

produce stuff from recycled plastic

4:13 AM

this needs 3 phase ac, which needs to be generated somehow

One thing guys

and the non-recyclables will be sent to landfill in most countries

How much energy does it take to downcycle?

Well nothing is created, nothing is destroyed, everything is transformed

4:14 AM

Reducing plastic waste mean turning it into something else safe

4:14 AM

Fuel ain't that

depends, it can be sort of "self sustaining" ie use syngas to heat reactor, asl CSP can be used, or waste heat from other heat processes

4:15 AM

electricity is used for all pp machines, where does it come from?

Yeh true

Personally i think hydrogen as energy source is more and more tempting

off grid is solar, (possibly small wind), and biomass mainly

4:16 AM

it is a good storage method ie fuel, but hard af to store

4:16 AM

outside of liquid (ie cryogenic)

Also solar Stirling engine are safe

i LOVE solar thermal to bits lol

4:16 AM

like

4:17 AM

m o l t e n s a l t s t o r a g e

But im not looking into continous input, intermittent input that produce useful labor is fine

definetly

4:17 AM

i made a sort of "anyting in" "power out" system plot, let me grab it

Also 100% industrial efficiency is not a concern just let thing get slow

how so?

I mean if people were making plants they would try to make race against time

4:19 AM

Maximizing output

4:20 AM

it is WAY more eco friendly

In fact i have start documenting it

4:21 AM

although not some of the art like on the left, more like old hdd cleanrooms

4:21 AM

sort of

But i had to find a way to pump water

very inconsistent and with humans you have pharmutical contamination

4:22 AM

pumping water is easy?

You need an energy source, also i implicit mean from stuff laying around me

4:23 AM

I had trouble making tube too

4:23 AM

Lool

everything requires energy of some sort no?

Yes but the way to collect it vary

4:23 AM

During covid with typical appartment trash i had nothing

apartments aren't entirely farm areas so wouldn't reccomend anything more than a planter in a fish tank

I want self sustain system with little human input as eco friendly as possible

4:25 AM

Planter?

4:25 AM

more so a gimmic

Anyway its a supplemental thing not a replacement

demonstrates the concept though

Do you know about foid computer?

i think spending time on developing would be more useful than apartment scale devices, my take at least

4:26 AM

let me look that up

I mean i want to experiment with it and find way to integrate all of that into a prototype automated personal factory

I’m going to eventually either purchase the Beyond Plastic biopress or have it fabricated locally (waiting on prices) but in the meantime, any ideas about how to start testing materials without the machine itself. Would I be able to use a 20 ton shop press, some moulds, and some dehydrated material and get similar results. Or does the binding itself come from the heated moulds? Could I just heat the moulds up in an oven before pressing?

1

i would assume you can do with what you have already? idk. Ive seen simple presses, and a binding agent work well for cellulose composites

1

Also, wondering if anyone has any recommendations for dehydrators. I have one but it is very old and doesn’t really dehydrate all that well haha.

8:30 PM

@Eric Lotze I’m definitely going to give this a try without heated moulds and with and see if I can make it work to at least start playing with material combinations.

dehydrate by heat, thermoelectric, or vacuum?

Heat

even an oven cracked open on low heat should work

10:12 PM

could even clamp mold shut, and insert in oven

I like that plan.

Hi everyone, I am looking to buy or a build a low cost shredder that is capable of shredding any type of organic food waste including left over bones or sweetcorn husks and small bits of garden waste. The aim being to process the waste sufficiently to produce a solution with small particles that can be pumped into a bioreactor. I have seen that the shredders have sharp thin blades, compared to others with wider blades. Would these be suitable for cutting organic waste? The system we are building is also off-grid, so ideally I would like to be able to power the shredder with a DC motor. In other videos I have seen the shredders being powered by a 250W motor. Would be sufficient if combined with a belt to increase the torque? Thanks for any help!!

Advice for people who are experiencing with cardboard recycling: Ahem, don't let wet shredded cardboard sit for long somewhere. Use it quickly (less than a week, ideally a few days) or throw it away. It's not like I wanted to know what happen if you don't but... it's bad.

Well, the good part is that it decompose well and is probably compostable but. Yeah. (edited)

2

Anyone have information on upcycling clothes? I've been looking for info to see if there was any process to take clothes, shred it, and recycle it into thread. Or can it only be processed into yarn?

2

@Uplifted no, but I am very interested in that kind of processes

@Uplifted any time you shred cloth, the fibers shorten and are weaker. The ways of combatting this depend on fiber type. Plastic Fibers may be recycled. Celluloistic fibers can be made into "Reformed Cellulose" (ie rayon and other processes), not sure on animal fibers (ie wool etc)

7:19 AM

Polyester is actually "downgraded" PET plastic

Hmmmmm that's pretty neat. Wonder what they do with recycled clothes. Or if they even can recycle animal fibers.

I have seen felps made out of recycled clothes and it’s used in walls for isolation

animal fibers are keratin

6:25 PM

Reaching out to see if anyone knows of a bioplastic that might work for an injection moulded welly boot?

Anyone know much about hemp plastic or the how to go about making it the write ups ive been hearing on hemp plastics is awesome but not much has been shared on the how its made? Any ideas?

8:55 PM

@Gemma hemp plastic might be an option for you bud degrades in 8 months out in elements lasts for ever if looked after. But not much is shared on it

Isn't hemp just another biomass crop. I have yet to see advantages to other crops outside of direct fiber usage (hemp rope), but post-rayon discovery i find that point irrelevant? Any papers on this?

I actually found a book on how to make jewelry with hemp.

1

Hemp from what i know allows good thermal properties and good clothing completely biodegradable and is a natural form of carbon capture with a fast grow cycle but hemp plastics seem to be a mystery i know they exist but unsure of processes or anything other than it breaks down quickly if left out in the hot,cold and wet.

Hi! Someone has tried to recycle rubber? I am interested in it because of its elastic properties. Thanks in advance!

rubber as in car tyres, cast latex, or what?

The car tyres usually has metal in it and it’s not easy to process

one thing to note about those is they will get "musty" and decompose easily

9:28 AM

"biodegradable" can be a plus or a minus lol

one thing to note about those is they will get "musty" and decompose easily

Yeah. If you keep it in dry environnement, like your desk, it's fine. But I wouldn't use them outdoor. I don't think they would survive the rain. Coating options could be explored, still.

I did a alt materials block in my hnd jewellery design and silversmithing course years ago i made a jewellery ring which was made from newspaper mulch i used starch and egg white to bind it.

@joshu i don't know how they do it but in craft stores you can buy those rolls, and they come from china and are very cheap. maybe they use new clothing tho. they are usually from cotton cloth (edited)

Precious Plastic - Make an edible bowl (part 8.2)

@hkdekisuki @krugars I neved had the plates "in my hands" so I can't really say, but my guess would be that they "degrade" easily in water. Not that much (for example I don't think a bit of salad sauce would pass through it), but if you wash them/rinse them regularly... yeah. I believe they're made to be a more eco-friendly take on single-use plastic dishes, and they're edible. I've been exploring thick-cardboard molding for a while, and there's a bit the same issue, probably somewhat worse. That's the issue with biodegrable materials: "going away with the wind" is part of the deal, it's both a very great advantage (I mean, it doesn't trash nature), but sometime it can be inconvenient. But if you're looking into reusable, durable "eco-friendly" dishes, I know it may sound dumb, but you can buy regular "hard" dishes, and reuse them 1000 times. They're fragile, yes, but they fit most applications. It's always a balance between your criterias (family home vs festival, lightweight vs durable,...) and "reduce, reuse, recycle" (trying to not create a product that will trash the planet.) I can see these kind of edible plate used in other context where you can't give everyone a "hard plate", for example maybe in a festival or some kind of place like that, or for outdoor activities.

Hey folks does anyone know the PSI on the plastic shredder? Reason im asking is i reckon if its strong enough and the blades are tough enough i reckon the shredder could be repurposed into a garden mulcher. If we take the idea of french drains and fill the drains with the garden shred mulch we have a bio site for plant beneficial fungi and a water retention barrier this could be a key in regreening non fertile land.

I think the idea of usage as a mulcher is neat

I'm willing to find a way to recycle it properly. Though first I wanted to know if there were a way to recycle it and recover something safely. Also if anyone knew a place that could do this for me if I paid them money to do it.

Until the food gets cold hehe. In our tests we ate soup out of the bowls and could refill and eat another portion. They seemed pretty solid :) But surely depends on which material you actually press. (pressed coffee ground is probably not as durable as wheat bran)

^anyone know of any attempts to open-source this process? This seems incredibly promising

4:52 AM

(the solar)

It's a little misleading title, as it doesn't actually generate electricity by itself. It uses particles from plants to convert UV light into visible light, which is reflected to the very edges of the panel and then used with normal photovoltaic cells.

5:24 AM

Still very neat, but not exactly "Solar panels"

Yeah more of a spectrum-side solar concentrator, but by it's seeming ease-of-manufacture seems like it could revolutionize solar energy (if you need X watt-hours to fulfill your needs, this will allow you to get to X with fewer traditional panels in total - it also opens up the opportunity for solar farms for ppl who don't have lots of horizontal land available)

hi there, i was watching beyond plastic video about making a bowl from orange peel

we may be interested to propose it to be used in an indoor market here in Milan

9:44 PM

it's not clear if after eating the salad you can wash the bowl and use it again or is it single use

9:46 PM

We were imagining to use it as a packaging, more than plates to eat in. Also because there are different safety rules which are more strict if you want to eat directly (edited)

Some important lessons to be learned here: China biodegradable plastics 'failing to solve pollution crisis' https://www.bbc.co.uk/news/world-asia-55301203

China biodegradable plastics 'failing to solve pollution crisis'

China's increase in biodegradables is outpacing its ability to degrade plastic, warns Greenpeace.

@Zoescope no, that is a new to me too.

The point is finding alternatives to take-away containers, which are almost never re-used, either. It all comes down to the "convenience factor." With hygiene being a close second.

1

I’m starting to think that the only way to stop this “convenience factor” is to eliminate the convenience. I wonder what a society would look like that couldn’t throw things away.

many traditional foods are wrapped in leaves from plants like the banana or cassava trees

8:50 PM

people bathed in rivers, the ocean

8:50 PM

you basically just have to wash things

8:51 PM

in ecosystem terms, think of the business and organism ecosystems as one layer abstracted from each other but with analogous structures

8:52 PM

we don’t have the decomposer businesses that process waste and reform them into useful raw material, like roaches and crabs

8:53 PM

but precious plastic is a model for that, sort of like a gene sequence, but the sequence still has to prove adaptability and get propagated throughout the population to have impact at the necessary scale

1

(i started r a m b l i n g TLDR: The "Detrivores" do kind of exist, also Plastic Definitely has some use cases, also pragmatism vs idealism ) "we don’t have the decomposer businesses" paper/(corrugated)fiberboard are EXTREMELY recycled. And in waste-to-energy, or anaerobic digestion, or even just commercial windrows composting this is sort of done. Granted plastics recycling in particular isn't really there, however this is really just due to "profitability", rather than technical capability. The moment fossil fuels are unprofitable (due to availability of resources (unusual oil, tight oil, and all that mess being all that is left), a Carbon Tax, or even just market pressure) recycling will SURGE. I think the real issue is with transport of goods, and in temporary services/use cases where washing and/or crying, often rigid + more heavy containers is impossible, or heavily impractical. I think the main remaining use cases for mostly single use plastics would be:

Liquid-Tight Containers
Drinking Straws (for disabled people, where holding/using a cup can be difficult. I prefer the "ask for one" system, not mass handing out)
Plastic Bags (for gas/vaportightness, and/or waterproofness )
Tape + Stickers etc

Also you need to consider how you can impact the "average person", some people already can live waste free, but you have to also get the person drinking only from single use containers (AND not re-using them) to be low/no waste as well in order to get a significant environmental impact. This requires accommodations as (most) people don't like change, especially when it affects their habits. (edited)

I don’t disagree with anything that you’ve brought up or linked to. There are definitely many, many use cases for plastic. My worry is that if we replace plastic with some other type of product you’re still going to get the offshoot problems associated with ramping up massive production of this alternative and it’s end-of-life byproducts. I’m thinking about a thought-experiment where you would wake up tomorrow morning and find out from some sort of higher power that you were no longer allowed to throw anything out into the garbage. What would you do? What would society do? I’m thinking about this in terms of site planning and Storm Water Management in civil engineering drawings. A site needs to typically be designed to manage a 1 in 100 year rain event and be able to essentially store the water that would rain on the site and effectively move this water into a series of pipes that brings the water safely away from the site without causing damage to the neighbouring sites or the municipal infrastructure. What if we did this with plastic waste too? Could we imagine a home of the future that managed its own waste on site? And the limitations to this system would be the inherent limitations on what the consumer could bring into the home. Like right now there’s no system stopping me from buying and throwing away as much waste as I could possibly buy. It feels like to me that there should be managed systems that slow down our consumption.

i was geeking out on stormwater managment a while back !

11:08 PM

On the note of that, with a household anerobic digester, and some sort of "kitchen waste grinder" you would probably be able to easily do that. Especially given in-home use doesn't need really any of those to-go / event things

2

like “garbage disposals” but for plastic waste types instead of food waste? or like the kind of paper shredders that go on top of garbage cans? the form factor ideas are interesting

i'll show it, i have one in my sink, but they aren't TOO common? Either way GREAT as a PILE of MSW is just organic matter. Have one of these, and a compost pile, and trash goes WAY down

If you have a sewage->anerobic digestion system it is very green, but easier to deal with than a compost pail (no rotting pail etc)

1:47 AM

Also prevents waste from clogging drains as you would shred it all

I want to see if one could shred PLA

if not you may need some sort of "utility waste shredder" in the garage or a utility room that is essentially just the Precious Plastic Shredder as a sink basin !

(edited)

Hello everyone!! following the line of the conversation ... From what I heard, we can make drinking glasses with these materials, but by putting water in those glasses, is there no danger that the organoleptic properties (taste, color or smell) will be modified? Wouldn't it be necessary to add a dividing layer (I don't know what material or components) between the drink or food and the plate?

1

The degradation is also relevant to product shelf-life, which usually needs to be six months or more. It's one of the major problems with the concept, that all industries involved (and probably consumers) will demand to be solved first. Case in point: the first plastic Coke bottles were made of a different plastic that allowed the CO₂ to sublimate through the bottle walls. By the time customers bought it, the Coke wasn't fizzy anymore. That's why they switched to PET and it became the industry standard. Product testing has improved since the 1950s, but companies, in general, are still just as short-sighted.

Until the food gets cold hehe. In our tests we ate soup out of the bowls and could refill and eat another portion. They seemed pretty solid :) But surely depends on which material you actually press. (pressed coffee ground is probably not as durable as wheat bran)

Hi are you able to press bowls out of coffee grounds alone? I can’t seem to get the formula right and I’m not sure if I need to add other materials such as bread to make it work. From the website and material book it states that coffee grounds can be pressed into very sturdy materials but I don’t seem to get it right.

@Uplifted You might be thinking of https://sheltersuit.com/ and the Make Anything channel. But you'll have to be more specific. Also, for now, move it to #just-chatting . I'm trying to get this channel back on topic.

@Frederik C (ZA) oops sorry my mistake.

It's fine. I've been asking for a better channel description, for a while. It's summarized in a pinned message.

https://en.wikipedia.org/wiki/Molded_pulp

Molded pulp

Molded pulp, also named moulded pulp or molded fibre, is a packaging material, that is typically made from recycled paperboard and/or newsprint. It is used for protective packaging or for food service trays and beverage carriers. Other typical uses are end caps, trays, plates, bowls and clamshell containers. For many applications, molded pulp is...

@Eric Lotze interesting about the Pulp. It was about 10 years ago when I was in NL that I visited a company called Paper Foam. They were making packaging for Intel and Motarolla. The cool thing was they were using Corn Starch and similar ingredients to make their molded pulp pachaging. I am surprised PP is not affiliated as it seems to be a #archived-beyond-plastic initiative.

1:09 PM

We expanded our discussions into consumer goods and shipping packaging, since it is similar and a huge waste creator. Also because take-away food and goods packaging often have a common "culprit": expanded polystyrene (EPS / XPS). So, it was logical to add it to the conversation (along with "bio-plastics" in general, although the term can be misleading since it can mean different things.) But the project is actually focussed on take-away / disposable food-safe containers. Requirements for food contact are, of course, a bit different.

Right @Frederik , got it, so it begs the question if you added corn starch, or what paper foam(R) uses can that be combined with the food container materials? (edited)

Countries' specific food safety regulations come into play. Bacterial growth and moisture resistance are the main problems I can think of. Oil seeps through the bottom of the average pizza box, that I'm aware of. It's just slow enough to be tolerated by consumers. But then commercial recyclers classify it as "soiled material" and refuse to accept the boxes. I don't have a simple answer.

1

One thing we've speculated about before, is using some kind of organic wax to create a "glossy," moisture resistant coating on pulp / mycelium type material. Such linings currently used in many paper cups and plates / hamburger boxes are plastic laminates. I haven't looked at viable sources of wax, yet. That's a whole other research rabbit hole.

Since it's an entirely Europe-based certification, I've never seen it, here. Not even on imported products. I only became aware of it sometime last year, I think. (edited)

I just found that on the page too! I've been looking for some sort of standard on things like that, guess austria has it?

Hi are you able to press bowls out of coffee grounds alone? I can’t seem to get the formula right and I’m not sure if I need to add other materials such as bread to make it work. From the website and material book it states that coffee grounds can be pressed into very sturdy materials but I don’t seem to get it right.

I have the same question.

Same question here. about to start playing with coffee beans but it seems to be little information about how they made the cups or bowl besides the video

Hi everyone, Does anyone know a sustainalbe way to create rubber products? e.g a small rubber pad say 10cm x 7cm?

Natural rubber can be harvested from trees. There are small scale farms that do this - if you dig around you might be able to find a supplier

"Latex" is a better term for that. "Rubber" is an oddly broad term, can mean latex, or thermoset elastomers, or anything elastic, it gets messy

Latex

Latex is a stable dispersion (emulsion) of polymer microparticles in water. Latexes are found in nature, but synthetic latexes are common as well. Latex as found in nature is a milky fluid found in 10% of all flowering plants (angiosperms). It is a complex emulsion consisting of proteins, alkaloids, starches, sugars, oils, tannins, resins, and ...

May I know what does it mean by ‘doesn’t work alone’ in the first photo? So if the product isn’t flat it will need a binding agent?

Has anyone successfully made a cup or bowl out of just coffee grounds?

hey @lusamui i haven't run this experiment myself but i'm pretty sure that if your mold is not flat you'll need to use a binding agent (starch, etc) to hold it together

Thanks!

1:28 AM

Has anyone tried pressing multiple bowls at one time?

with multiple molds?

1:29 AM

or a production run?

@BC Ben on a snall scale it is not sensible as the tonnage provided is divided by the tools used. Stacking or an round array would divide the tonnage a d increase to tool cost. So if tou have the money, physical space and 20 t force per each, so a 100T press per 5 tools for example it is conceivable.

I tried with less materials and the explosion stops just a bit of materials get spilled out of the edge. Thanks for the advice! Here is a photo of the inner mold

Anyone encounter this? The material just couldn’t form into shape, they either break apart or get very uneven like a bad cookie. I’ve tried with different temperature and minutes using the material book as reference.

how finely ground is the bread you? enough to mix evenly with the grounds?

3:15 AM

bread you're mixing in**

3:19 AM

if the bread can be ground finer, i'd try that. if not, then keep testing time/temp settings. it might also be worth it to try a different binder (potato starch for ex.) to see how results compare. the bread you're using might have different characteristics from the one in the recipe book so it is probably worth it to experiment w material ratios to see how that helps.

I blended it with a kitchen blender as instructed, yea probably I should adjust the ratios and it’s the not same bread. I see that wheat bran does not need any binder, is it because it has a lower lignin level than coffee grounds? (edited)

Hi @Ainhoa did you find anything on recycling rubber? I know youcan recycled natural rubber but only 3 times...I would be interested if you know something different?

Hi Gemma, Thermo Plastic Elastomers (TPE) are very similar to rubber, but can be recycled over and over again (Up to a certain point). There are different grades of TPEs, with different shore hardness

Unfortunately, they are not the bio alternative you are looking for but at least they can be recycled.

Hi all! My name is Emily, I'm new here. I'm from NYC and was wondering if anyone knows someone who is working on/has the bio press? I'm super interested on making one!

I just watched the video about the mealworms!! I think is totally worth trying.

1

Yeah, some people in the group have done it. It's apparently just difficult to scale up because they eat so slow, live for such a short time, and need some other food source as well. So, for large scale, partnership with a commercial farm might be necessary. So, you try to "close the loop", by taking waste from the farm, feeding the waste and EPS to the bugs, and then feeding the dead bugs to other animals. Similar to the combination cockroach and chicken farms in China. (Although the people also eat fried cockroaches grown in sterile environments.)

I also found this interesting research from Stanford, where they confirmed that the worms poop the harmfull additivs such as plastizecers and fire retardants, so they are fine to eat or be eaten by chickens. I thinks is totally worth trying!! https://news.stanford.edu/news/2015/september/worms-digest-plastics-092915.html

Plastic-eating worms may offer solution to mounting waste, Stanford...

An ongoing study by Stanford engineers, in collaboration with researchers in China, shows that common mealworms can safely biodegrade various types of plastic.

That's how I understand it, yes.

Granted my fear would then be that Plastics would "rot" like wood does. I think the fact that it doesn't degrade short of UV is one of the amazing things about plastics. It is HELL when they are unintentionally released, but for structual uses etc, their hardyness is important? Also seals and stuff. Granted this is inevitable to an extent, but i am not too onboard for accelerating the trait

Hello, I saw the bio press and wanted to built one but I am curious, why is it a better method instead of using an injection mold machine. Maybe you don't need the thermal process like when using plastic flakes because you are not going to melt your materials but If you blend it in a pulp then injecting them in a mold makes more sense to me. Lastly you can "bake" the mold with the material in an oven if necessary.

It's a super neat idea! the only thing I'm worried tho is using the term "vegan leather". I mean it's not a bad term in this case, but usually, it's used as a (marketing) term to refer to cloth made out of PVC. (Which is then very leather-like). But PVC is... not great. And it would be bad if peopled assume that their "vegan leather clothes" are naturally grown. :/

If I understood @Jannis // Beyond Plastic ' documentation correctly, pressure and heat is needed for new mollecular bonds to be formed between hydrogen in the moisture and cellulose in the organic material, making the resulting material hard. What I mean is, if that's the case, injection molding and post baking may not result in a hard mass in the shape you like, but more of a brittle object... I may have understood wrong though, so far I have no experience in this. maybe someone else here does?

with the bio press, the molds must have very tight tolerances so that the moisture doesn't excape during heating and compression, also

También estamos interesados en utilizar un recurso local para la producción de los mismos, pero desvariamos hacer test de los materiales obtenidos para comprobar su viabilidad. Gracias We are still investigating with my team, how to address a need or opportunity in this area (replace one use plastics), through industrial design.

Ho c'est beaucoup trop chouette ! La vidéo rend super bien également ! ✨ ça fait vraiment plaisir de voir ce genre de projet en francophonie

Je me permet juste de t'ennuyer encore un peu : En faite , moi-même et une pote, nous sommes deux étudiantes en entrepreneuriat au Danemark (so we speak english between us haha) et notre projet de stage pour les prochains mois tourne autour du même concept que vous à l’exception que nous nous focalisons plus sur le côté « business » de l’affaire pour nos cours. Le problème pour le coup, c’est donc qu’aucune de nous-deux n’a de connaissances technique nécessaires pour comprendre au mieux la machine comme bio-ingé ou design industriel et celles-ci seraient très utiles pour mettre en place le projet avant de potentiellement le lancer sur le marché danois. Aussi, je me demandai si ça te dérangerai qu’on s’appelle une fois pour discuter de cette super machine ou autres !

Curious if anyone has experience or looked into polyster pelletizing.

Hello! Im new here, i came from the precious plastic series of videos. I am planning to try to use rice husk or even its stems, or sugarcane bagasse, or corn stems/leaves (they're my town's main produce) to create bowls,plates etc. Has anyone tried it?

Any one working with Kombucha Leather? Here is a great video, specially towards the end, because it explains a process to threat it after fermentation, which has been a problem for me! https://youtu.be/Ds8ZFzOwGeI

this looks like a good alternative for plastic wrappers/bags

Plastic Wrappers are very odd with the "Vapor Sealed" and what they let in vs out, but for a basic seal it may work

Haven't tried your bowls from stems or corn leaves specifically, but your question reminds me of these mycelium bowls: https://www.instructables.com/Mycelium-Bowl/

Mycelium Bowl

Mycelium Bowl: This project will take about 10 days; 4-5 days for the mycelium to start growing and another 4-5 days for the mycelium to form to the mold. The first part will be focusing on the pre-mold phase.

Morning Everyone, i am thinking of a low tect machine to recycle power cords. basically sort the plastic on one side, and the copper on the other side. is there anyone with the same idea and willing to share ideas ? i ve done some drawings and building the first machine with square tube and angle from the injection and shredder making. thanks !

Hi everyone! I am very excited to be here!

I am going to build a biopress to help my business come closer to zero-waste. We produce fermented veggies and drinks, and have a heaps of vegateble shells as waste. Right now im in the stage of just learning as much as possible about the machine, bio pressing and mould construction. So, my humble ask is if anybody has some material that was helpfull in their understanding? Also, since im based in Sweden i would love to get in touch with any Swedes who might have built a machine? And of course all input of any kind is very welcome :))

Hi guys, I was wondering if anyone has ever build a Beyond Plastic Machine with two trays instead of just one ? LIke to create two bowls instead of one at a time ? Would that change a lot the price of the machine when building it ? Is it possible ?

Hey friends, has anyone here experimented with composting the shredded plastic? I’m looking at spores like this https://northspore.com/products/plastic-degrading-mushroom-cultures

Plastic Degrading Mushroom Cultures

Cultures are made to order as agar plates or slants. We do not sell liquid culture at this time. Pestalotiopsis microspora NSPM1: Promising for bio-remediation projects, Pestalotiopsis microspora has been found able to degrade and digest polyurethane.

A related question, since a bunch of clothing is stretch and that’s plastic, can that also be shredded for composting?

Hi everyone, i would like to know, after the plastic been make into something, can I paint or spray color on the plastic products?

I mean yes, just like painting any kind of plastic, but if you're trying to keep chemicals and plastics out of the environment it's probably better if you can sort your plastic by color and get what you want directly out of the mould.

Question: This might sound dumb, but here goes, is there a way to recycle plates?

6:21 AM

My initial idea was to crush plates into dust, then mix stuff together to make it clay, then make them into pottery.

TL;DR Yes you can, clay can be mixed with crushed and powdered ceramics, which is called grog. It usually gives the clay a bit of texture, sort of rough. I think (don't know for sure) it's important that the grog that is mixed in is the same or a higher cone fire than the clay (and possibly also unglazed?) to prevent melting in the kiln when fired, which I can imagine might be hard to tell and get from unmarked ceramic plates. It's possible, but usually when you're making ceramics you end up with failed and broken pieces anyway that end up as grog, and so I don't really see this being a great way to recycle plates. Too much grog in the clay makes it weaker as usable ceramic wares. I think the best way to recycle ceramic plates may be in mosaics, or even maybe sand paper if crushing is your goal. Thankfully ceramics are not harmful to the environment in the same way plastics are, and reincorporate in the same way as stone and minerals from my understanding, so recycling them isn't super necessary. Especially if you buy ceramics from local sources, and they last you a very long time, there can be very little footprint in production as well. Now mass production plates and ceramic firings in china maybe that's an issue... but it requires deincentivizing the consumption of those plates, and regulating those companies mass producing them so there isn't a profit to be had. So in conclusion I don't think recycling plates is very necessary, just buy local, or repair, to reduce mass production and transportation which causes the bulk of the harm. (edited)

Thank you for that info!

9:24 AM

I ask because my work is in trash. I happen upon many things that are thrown away, such as cups, plates, glasses, and the like.

9:25 AM

I wish to know how to reduce as much as possible and studying to come up with a game plan.

Hey there! I’m looking into working with spent coffee grounds and developing local circular economies, has anyone had experience using the heat press with any coffee ground recipes? If so, what kind of material properties do they produce? Thank you!

I've done a project similar where I recombined paper with lignin and molded it. It had some promising results but I didn't continue with it. I didn't use a heat press, just a compression press, and a heated press to drive off the moisture might work better. I would also recommend the video @sponsoons posted, I based most of my work on that

with lignin ! I am especially intrested in that, because that is what is removed from the wood to make paper pulp, so you can sort of re-form the wood! (short of the long, non chopped fibers)

I didn't use heat press either. I basically CNC-ed an aluminum mold, I also used metal screens for the mold (but this is very hard to get right) and pressed the pulp. Maybe if i use heatpress I wouldnt need screens. As for the binder I used starch. (edited)

maybe one day (very soon) that will become cost-efficient enough to be mainstream

Is Thermoplastic starch technology is bio plastic, is this the best channel to discuss? Do we have a wiki of everything the community knows about processing plastic?

maybe one day (very soon) that will become cost-efficient enough to be mainstream Yes, that's step 1. Step 2: Make it easy, cheap (enough) and environmentally friendly for fast food companies to stick all their pictures & logos & shit (that they spend millions on) on the containers (since they will probably insist on it.) Step 3: Convince consumers to insist on using the alternatives, even if they are less convenient and cost a few cents more. I'm also keeping an eye on how Uber Eats's returnable glass containers program works out.

Hey, a bit late, but you can contact us in Maastricht!

Hello, I saw the bio press and wanted to built one but I am curious, why is it a better method instead of using an injection mold machine. Maybe you don't need the thermal process like when using plastic flakes because you are not going to melt your materials but If you blend it in a pulp then injecting them in a mold makes more sense to me. Lastly you can "bake" the mold with the material in an oven if necessary.

Good question. Biomaterials genereally are not homogenous polymers. With injection moulding preferably you have one homogenous substance that has fast cooling and fast crystalisation. Because of the mixture of polymers in biomass, they have a range of thermo-mechanical properties. To find an injection moulding setting for all of these materials, that would be difficult. Hence, compression is more suitable for this mixed material. If you manage to try it, let us know how it works!

Concerning The biodegradable Bowl and Cup. How long can you store them for . Is there a shelf life ? Can you use the more than ? thank you for any replies .

Good question. We would love to bring our cups to a testing facility to get this answer in the future. I've made bowls that stayed unmouldy for 3 months (without using it).

Hey guys, does anyone know the water to weight ratio when adding water to your dried biomass when using the beyond plastic press?

Hello everyone, I would be interested to know if anyone has had any experience with duckweed, especially people with an bio-press. I am currently working on this and it looks like the duckweed can be shaped with little pre-processing and little temperature due to its high protein content. I am looking forward to any tips, also if and where there is someone in the Netherlands with such a press who would be willing to support me in doing some experiments.

MeesGroothuis

Hey guys, does anyone know the water to weight ratio when adding water to your dried biomass when using the beyond plastic press?

In the "Material Book for the Beyond Plastic Bio Press" , they add 10-20% solvent (water or glycerol). According to the scientific literature on agromaterials, you can also use a "dry process" by using the natural moisture of the ingredients (at equilibrium, all components are not 100% dry, but have ~5-15% moisture) at higher temperatures (180-200C).

Polyvinylpyrrolidone

Polyvinylpyrrolidone (PVP), also commonly called polyvidone or povidone, is a water-soluble polymer made from the monomer N-vinylpyrrolidone.

hi @Liri (They/He) thanks for the answer, I thought there were about the plastic material, I m missing to know where could be the channel for discus the business aspects, hopefully will be there. all my best wishes

@Lixeiro that's actually a pretty good suggestion would be a cool addition to the channels! I think the only thing close would be the Bazar sellers but I think you can only message there if you are a seller

I'm not entirely sure who is in charge of that maybe Mattia or Eric Lotze or a moderator? definitely ask your questions in #archived-plastic and add that suggestion to the #deleted-channel channel :D

Hi everyone I’m from the Philippines

5:05 AM

Please let me know if this is not for this channel. I want to learn how to make products which can be sold as alternatives to plastic. For example, I saw a video on YouTube called world wide waste season 1 marathon and a couple were making eating utensils out of pineapple waste. There’s a mom and daughter tandem from here who sell packagings from sugarcane bagasse. I tried my best to Google processes of creating bioproducts but the results are just mostly sellers selling products. I want to make products of my own and give jobs to people here. The closest I got to an actual process is a wikihow that doesn’t seem practical because it teaches how to make sheets on baking trays using chemicals I don’t even know how to acquire. Can someone please help me? Thank you so mucj

@Maricris - you can search ‘papercrete’ basically, it is mixing cement and recycled newspapers to create functional objects. Hope this helps.

Thank you so much

take a look at making 'straw board'

it actually doubly applies to you as it uses rice/wheat straw for making cardboard/paper board or at times paper

7:25 AM

but take a look at how that process makes pulp out of straw

Thank you so much sponsoons I will Google that. My savings are affected because of the holidays huhuhuhu I have to pick a sustainable business considering my current savings. I’m sure I can get supplies of rice straws but the exact process might require machines I can’t afford

It’s difficult to find detailed diys for the straw board and papercrete. Another problem I have is my location. The people here are not that interested in caring for the environment and would prefer buying cheaper materials than environmentally friendly ones. It would be a difficult market. For example, trash collection days depend on the type of trash but people here mix their trash together in one bag for convenience. RIP SEGREGATION

I was looking into engineered bamboo products, and that seemed especially interesting! The growth rates of some bamboo species are insane

10:22 PM

and that is either "naturally" or via (in retrospect) primitive artificial selection, throw some modern genetic engineering in there and we can have Super-Bamboo sucking carbon out of the air and fueling this whole sector in a fraction of the space of equivalent tree plantations

10:24 PM

Also i wonder to what extent native grassed could be used; i've looked into this for bio-energy / bio-petrochemistry, but for woody products is interesting with fiber length / need for lignin and whatnot etc Being in the USA / North America, we have a pile of grasslands that have been devastated via agriculture, so being able to "semi-rewild" them intrigues me

10:25 PM

I think here in Florida we have quite a bit of "Longleaf Pine" tree plantations/farms, although most are done in the "row" method, which if i remember correctly is good for wood, but bad for forests, if that makes any sense. Kind of the whole mono vs polyculture thing

10:28 PM

10:30 PM

I think most photos seem to be taken intentionally at an angle to make the pictures look more "interesting" but as you can see by that front row, they are essentially just regularly spaced rows of regularly spaced tree, and some brush, although that is frequently cut / controlled burned down

10:30 PM

This makes it easy for harvesting, but little biodiversity

I need to look into more how the opposite of this is done, the sort of re-wilded commercial forestry

Hello everyone! I’ve seen that some of you were interested in paper pulp and I thought of sharing an open source project I’ve been working on with a friend of mine. We are testing a series of recipes to combine paper waste with natural ingredients (like flours, starches, resins, alginates and gums) and a series of low-tech tools to press the pulp and create sheets, bricks or other basic shapes. For the tools, the idea is to use just one material (we mostly used wood but also a recycled plastic sheet from Recycle Lab in Lisbon, Portugal) and no glue, no screws, to make them as simple as possible and easy to assemble/disassemble. Some were made with traditional woodworking techniques, others with a CNC in a local fablab. You can see something more here: https://www.instagram.com/postpaperstudio/

Now we are testing the properties of the sheets and bricks (especially how they can be worked with traditional tools and digital fabrication tools) and coming up with examples of objects and products that can show the value of paper waste. If anyone knows any other open source project related to small-scale paper recycling, or if you have any interest in trying out the recipes and tools, please reach out! We are still at the very early stages of development and it would be cool to share knowledge and expand the possibilities. (edited)

Cardboard is also an interesting substrate for growing mycelium. It is almost entirely cellulose, which has no nutritive value to any organism except wood-eating fungi, so it remains effectively sterile. That means you can rapidly cultivate mycelium on it with minimum labwork.

I need to do some looking, but some people here on this discord were looking into doing something along those lines, and as shown in that video (i also dug up some stuff on that, it’s formally called “Molded Pulp” ) you can do it even with stuff you may already have.

I remember OSE had some page on “molded mycelium” but i think that was pretty much information only, no work has been done on that yet by them. Next time I’m on a proper computer (on my phone just checking discord now) i can try and look into it more. Granted mushrooms are also just yummy too!

Uplifted

Yes but I meant to do that on a self manufacturing level vs mass manufacturing level.

it is also totally possible to make paperboard from recycled paper on a small scale! i have been working on getting a paper recycling workshop set up in my basement, there's plenty of online tutorials on how to make paper by hand, small scale! it's pretty cheap too, you don't need much materials and most of it is stuff you could find at like a thrift store/used goods store for cheap. ie. a regular kitchen blender to process the paper scraps into pulp, a mould & deckle (the thing that actually forms the sheets) from a couple old picture frames and some screen from the hardware store, etc. i was able to find all the stuff i needed for less than 50 bucks. the stuff i'm doing is making thinner paper for prints, bookmaking, and likely some smaller packaging, but i definitely think it would be possible to make a thicker paperboard! making corrugated cardboard this way would of course b pretty labor intensive since youd have to like, fold and glue manually, so that might not be doable. also if i recall, there's a limit to how big you can make the sheets. so you very well may be able to make boxes this way! - just depends on how big & strong you need the boxes to be. (edited)

Hi, since a Cardboard is a layer of different kinds of paper it will be very labor intensive to produce by hand, if I know think of ways to make the structure of corrugated. Also packaging paper so bags and cardboard have a so called Clupack Unit in their production line which compresses it so it gets it gets more strength. Not sure if you can compensate that step with just using more material.

Have you guys heard of straw board?

its basically paperboard but it uses a good amount of straw or agro waste as it is much cheaper

due to being a solid board it isnt as strong as cardboard/corrugated but its still used very often in packaging as it is cheaper

found this cool artist making some funky art out of recycled paper lately :D

Has anyone tried using the plastic extrusion to recycle masks?

guyz i finally built a bio press machine..these are first tries made of orange peels..i also have a coffee roastery so i have plenty coffee grounds so the next goal is a cup made of coffee grounds..so here is the question... i dehydrate them after the press..they become more sturdy after but not sturdy enough...they are still feel a bit fragile..i can make it a little stronger i guess by increase the thickness or by increase the cook time (just guessing). the main problem is when you put water inside you can taste the orange and you can see very small orange particles inside the water...and the cup becomes little soft again after even cold water...so drinking coffee or tea from this is not a good idea..so what we need is a coating (with smtng food safe or food grade)...im thinking about bio resin (pine resin)..what do you guys think? what else can be done to make this waterproof heatproof reusable washable ?

Well done mate! The results look very promising for a first try!!!

9:49 AM

Use a natural binding agent, for sturdiness & protection. Maybe if the combination is good enough, you might not need any type of coating (which adds an extra step in the process and I guess makes the object less compostable) Maybe try de-hydrating more your orange peels to see.... I'm curious if you have the same result with coffee grounds

It looks quite nice ! I think you can get more natural binding from the stuff in the orange peels (pectin, cellulose, etc) by playing with the pressure, temperature and pressing time. However, getting to a heatproof and washable material is a long stretch, I don't think we will get there with pure orange peels and mere thermocompression. This is a massive challenge for anyone working on these materials and there is no magic solution at the moment: either you use some synthetic coating and you get nice properties, or you use a simple natural ingredients and you cannot expect great properties. Food contact is an additional issue.

11:10 AM

Coffee grounds have no cohesion whatsoever, they are pretty bad for thermocompression. That's why they add stale bread in the Materials recipe book, probably the starch in it acts as binding agent.

Tea is suprisingly good for cohesion on the other hand. This is what I get with an industrial thermopress (used for plastics in my research lab).

The reusable Weducer Cup made from recycled coffee grounds is the ideal companion for the conscientious, design-oriented coffee lover.

nothing much probably, iirc either corn starch or maida is used as a food safe binder in most of these things

Hard to say, but I think there are biobased polymers to make injection possible. Usually people who use PLA claim 100% biobased and compostable (like them: https://repulp.fr/). Here they write "Kaffeeform is a new composite material consisting of coffee grounds, biopolymers, starch, cellulose, wood, natural resins, waxes and oils."

Tetra Pak® recycling ::: nice, easy and efficient

i was collecting tetra packs with the plan to build a large solar collector (still don't know how good the material is for that purpose), but than, because lack of time i gave up that project. But i am still curious if it would work or not...

Also, if anyone has already made the "bio-press" were there any major troubles in the process?

we found out that because the heated aluminum block and steel plates hang in the frame, they get pushed up during pressing. This bends the steel plates after long use because they get stuck behind part of the frame.

Hi there, I am a student at a university in Australia, we are doing an interview on activism with plastic, if anyone is able to answer some questions that would be great! 1) What happens to plastic that cannot be recycled? 2) what do you think is the biggest problem with plastic? 3) why is plastic controversial? is plastic evil? 4)does banning single-use plastic even make a bigger dent in the problem of climate change? 5) is there anything you think RMIT can do better with plastic waste, and what tools do you think will be needed? 6) when we ban plastic, doesn't that force us to use other materials that are more expensive, and energy-intensive? shouldn't we keep using it, but just get better at recycling? Thank you so much!

1. It gets burned or landfills 2. Our reliance on making more of it 3. It cements our reliance on fossil fuels and has no effective end of life handling. 4. Yes, the definition of single use needs to just be expanded beyond consumer single use. Industry uses waaaay more. 5. Idk rmit but generally attempting to use as little plastic as humanly possible would do a lot. 6. Other materials are less efficient but that's very much because we don't use them at scale yet. If we can have more energy intensive co2 neutral materials, the energy can come from solar or wind.

Recycling also only works 4-5 times before the plastic degrades too much to be used anymore

Hello. In my humble opinion: 1) It does get incinerated for heat, (for energy production) or burried in landfills. In some cases, it might not be recyclable by precious plastic methods, but it can be recycled industrially. In some other cases, it gets recycled crudely into large beams that can be used in outdoor furniture, walkways, fence beams, etc, like Extruplás does in Portugal (https://www.extruplas.com/en/) I'm not affiliated 2) One of the largest problems is also one of it's main qualities: it's durability. If we keep making single use products with a very durable material, be it plastic, stailess steel, aluminium or glass, there's inevitably going to be a lot of waste, not only in material cost, but also energy needed to produce it. 3) Plastic is a great material, it's just sorely misused. We want to have durable products, they help reduce energy consumption, be in heating or cooling, os simply by not having to replace them as often. But making durable trash is a terrible (evil even) idea.

3:01 AM

4) It will help, maybe. But replacing single use plastic item by single use any other material items won't help that much. What would help is to change out mindsets and reject as much single use objects as possible, inconvenient as that may be. 5) Royal Melbourne Institute of Technology? hadn't heard of you before. A university is a great place to educate, change mindsets, plan strategies and generally coming up with better ideas. Come to think of it, materials engineering and design are just a couple of fields of study that can easily apply eco-friendly ideas to ground breaking solutions. 6) Some other materials can replace plastic in some products, but there's no magic bullet to replace plastic other than being more conscious about what products are made. Consumers can actively chose what to buy, forcing producers to stop wrapping cookies individually, but I digress. yes, some materials will be even less environmentally friendly than plastic. We should get better at recycling in general, but more than anything, more consciencious. Thanks for your questions

Mixed 40% by volume aluminium chips from my cnc machine into LDPE, made a composite that was substantially more rigid than plain LDPE, while still having nearly the same flex (much hard to get it moving, bit still moves the same amount) might try glass fibre or hemp fibres next

can't find in the threads who wrote that, i'm still a little confused by discord. yes, i'm from berlin, but would also order one from somewhere else. there is a machine on bazar from the netherlands, but it isn't available at the moment due to personal reasons from the guy who normally builds it. therefore i'm searching for any source where i could buy one from (or who could build that for me) (edited)

Hi folks! me and my team are on the way of finding a way to make a cup that can actually be used to drink coffee. Coffee grounds and stale bread actually works, but is not the strongest combination to hot water

I think coffee cups are not a good application of these materials, despite being quite tempting. If you look at the material properties, it is strong, it has a hard surface, it is pretty light, it might have decent fire resistance. But it is inherently poorly resistant to water. So why are we trying really hard to make something that is in extended contact with hot water ? I think it is a design issue more than a technical one. Having said that, if you manage to do something that works, it will be amazing ! But I am not sure it is the application we should start with.

I also wonder about the durability of these, and how they react to hot liquids

10:56 PM

I scrolled up and already saw some inputs, my bad! But would it be a good idea to coat something biodegradable? Even if it was an organic protective layer, would the product be able to decompose afterwards?

I scrolled up and already saw some entries, my mistake! But would it be a good idea to coat something biodegradable? Even if it was an organic protective layer, could the product break down afterwards? I ask myself the same questions, it would be very good if one of these pieces is not disposable but for daily and continuous use as is any bowl or plate. That they can be used, washed, dried, stored in the cupboard and be able to use them again (without generating mold or any other type of decomposition).

/Hello everyone! I work for a company that uses biocomposite (wood waste) as a material for one of its products. I wonder if anyone has any experience using this material on the machines. If so, I would love to hear about your experience. Looking forward to reading your messages!

Hello everyone, I am writing a book about packaging and the consequences it has in the world. I would like to know if you have any resources on new materials, articles, podcasts, videos. also on plastic and its consequences. Thank you very much!

@Ale Bottos @herzterben they are not really washable. how much water they can tolerate depends on the material they are made out of. i've coated an orange peel bowl with shellack, bc it's a natural coating, but haven't tested its biodegradability yet. i guess these products can't be an alternative to typical plastic products regarding their properties. but there are other products they can be useful for. biobased products will always loose compared to plastics, i would rather compare them with products made out of paper/cardboard i.e.

Hello, we're finally moving onto 3D objects in Strasbourg, they are 100% waste, no added binder. I spent quite a long time adjusting the parameters to have a nice material that gets its cohesion from the biopolymers inside the resource (proteins, polysaccharides, polyphenols, etc). So far, I have tried: apple pomace, spent tea leaves, brewers grains, coffee chaffs, wheatbran, and potato peels. When I have time to do so, I will share the recipes online. And we'll have a Master student working on an advanced version of the biopress next year, during a 6-month internship. The idea is to have a professionally-made biopress. It will make it easier for craftspeople to heat-press organic waste into objects, without having to start by building their own equipment. If you are interested, we can set up a chat to do collaborative R&D on this topic.

Hi Jess! It looks simple to build. It's a box where you can put a heater (electric resistance) to work with an PID system to control the temperature, with a fan underneath it. Just like an air fryer, but less powerful. Does it make sense to you?

[Doubt - Compression Spring] Hi guys! Nice to have you here. I'm building a biopress in Brazil and I'm running through some questions. The Compression Spring is specified to 7.5x5x20mm, but on account of ordering a spring, i need to specify the following dimensions in the image. As being: d: material diameter Da: external diameter Di: internal diameter Number of Total Turns Elastic Constant (K) Total length Number of Active Spirals Nominal step I'm sure I can get to these numbers if I drill down the project, but don't want to lose test material. If someone has already had it done, could you help with this question?

@Marion R - Atelier CirculR Hello, I am interested in knowing about the parameters and recipes that you used? Without the addition of any binder, you said? Just add the raw material and press? Or add a little water? I would like you to tell me a little. This is my email ale.bottos.vt@hotmail.com Thank you very much for your contribution, in advance!

I add around 15% water, depending on the by-product used (wheat bran for example requires no added water, while spent tea leaves are quite sensitive to low water levels). I am in the process of writing a tutorial with all the parameters, I will hopefully have it finished and translated by the end of January.
