PETG

I have a donation of 25 tons of PETG in the form of used clean drinking water glass from a large restaurant chain. The cups start looking bad after 3 months to they are replaced. I am familliar with PET as I have processed a lot of it. I have also used PETG in 3d Printing. Very familliar with its properties in that aspect. I do not have ability to process filament. That would require a complete expensive re-alignment of the shop. However, I am looking at plastic lumber, or grinding and selling for waste processing. It would make a incredible tough board. But at the expense of UV resistance without a coat of paint. Any suggestions here?

Can you anticipate a future annual supply? If so, that sounds like (possibly) the basis of a sustainable enterprise worthy of development. Before discounting the challenge of diversification as a threat to existing business, could it be worth your time to reckon what (and who) that business model would entail?

I'll be interested to see your results! I've experimented only a little with PETG in an industrial injection molder, and it seemed to work great, but that involved a 28 ton press and also proper moisture control/drying.

I have available 25 ton every three months. I am not really set up for a sheet production line. More just interested working as a collection/shred business model for this item.
