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 think we can only ever reduce the amount of plastic because literally almost everything is contained with some plastic. Even aluminum and steel cans are lined with plastic. Even paper packaging is lined with plastic. Personally I don’t think we can reasonably eliminate it entirely.
