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?
With return policies we don’t need to go through actual recycling methods. I don’t know if growlers are popular in your area but it’s pretty cheap energy-wise to just sanitize a returned jug.
Reduce, Reuse, and Recycle… specifically in that order.
