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?
You can reuse jars, ideally you would buy new lids, though when my mother or grandmother would make jam they would reuse “good” lids and the jars would seal well - I found a 20 year old reused jar and lid still sealed
Good lids being those where the seal is in good condition
There are very few lid sizes and threads
