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?
Nuclear, deep-well geothermal, and concentrated solar are all good, low-impact thermal power options. We should always be improving energy efficiency, but I just don’t see why we have to reduce energy consumption so much that we can’t have reusable metal and glass containers anymore.
