How do we package food products sustainably in coming decades? (lemmy.world)

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?

Those aren't really good either. Even glass, as much as it is better, still needs yo be washed and reused which uses more aggressive chemicals than most would be comfortable with.

Fact is that like everything in life, stuff is a tradeoff. Can we wash and re-use glass without aggressive water harming cleaning fluids? Sure. But that means more danger from it. We could also use degradable plastics but those are problematic as well. Tins are an issue in general plus they can only be used for some foods. Waxed paper is even trickier to recycle than most other things, not durable, and again only suited for some foods.

Ultimately, it's health vs recyclability. There's always a tradeoff.

Your criticisms about washing are only valid if we assume liquid water cleaning. Superheated steam will burn off any organic material without any additional cleaning chemicals.
