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?

Go to a grocery store, bring your metal containers to the grocery, get them autoclaved while shopping, and get em filled up with your rice/cereals/juice/etc.

Edit: The below is a bad idea unless new materials are found, see comment thread.

Also, SLA Printing for ceramics is already possible, just expensive for now. Once we figure out how to do that sustainability and in a foodsafe manner, we could just print our single-use cups and dishes from a slurry.

Yeah, finding the gunk from a bone dry ceramic cup left in random places outside would suck, but nature would be able to reclaim it as easy as any random dirt clod. (Well, not as quick in the short term, but when it comes to materials)

One could potentially even just rinse out the clay, stick it in some water, and with some elbow grease and effort, process it into actual, useable ceramics. Depending on the formulation required for the SLA process, of course.

I wonder what happens to ceramic when it degrades over time. Does it become microscopic pieces?

Ceramic is made out of clay. So yes, microscopic dirt pieces

@FalseMyrmidon@kbin.run True but I just want to add the super pedantic point that they have started adding polymers to them! And for cooking materials, too! It's very yikesy to me

Presumably something made to be biodegradable would not include polymers
