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?

Like we can grow in a building in the city way more efficient than long hauling.

Not really, no.

Farming in the city means giving up all the things you could otherwise do in that space. The farmer's field is only good for one thing. The building in the city could be used for thousands.

Adding the transportation cost to the utilitarian value of the farmland, the sum is still a tiny fraction of the value of the building.

Farming locally doesn't mean use a city building, it means use a field thats kinda in the same region, not at the other end of the world. And of course that's more sustainable. The shorter the transport routes are, the better.

There is projects using the outside of buildings, tops of building, and all these empty office buildings. It is probably best to density the suburbs and transport into the city which 5-15 miles is extremely sustainable comparatively to thousands
