I imagine all plastics will be out of the question. I’m wondering about what ways food packaging might become regulated to upcycling in the domestic or even commercial space. Assuming energy remains a $ scarce $ commodity I don’t imagine recycling glass will be super practical as a replacement. Do we move to more unpackaged goods and bring our own containers to fill at markets? Do we start running two way logistics chains where a more durable glass container is bought and returned to market? How do we achieve a lower energy state of normal in packaging goods?
I am talking about though is SLA printing though- resin printing, but without the resin, basically.
Which is why I think its more feasible than just extrusion printing on principle. The layers are incredibly thin, with no extrusion involved, and no exposure to air until well after the layers are formed.
