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?
Ok, but we’re getting dragged into a tangential debate about farming when really my point was that we need to look at waste through the whole supply chain, from farming ingredients to getting put on the shelves. I’m sure we could pick apart the contribution of any one part of that chain and debate how significant it is. Together, at all points in the chain, there is plastic waste that the consumer doesn’t see.
(And btw Canada isn’t in the top 20 of global producers, according to the IMF / CIA World Factbook as at 2018; the EU is number 3 https://en.wikipedia.org/wiki/Agriculture)
Edited to add: this 2022 UN report states that plastics are used extensively in agriculture and goes into how they are used and how they enter soil and water supplies: https://wedocs.unep.org/bitstream/handle/20.500.11822/40403/Plastics_Agriculture.pdf
And this is another UN report on the issue, stating that Asia is the largest user of plastics in agriculture. When China and India are two of the largest agricultural producers, that’s an issue https://news.un.org/en/story/2021/12/1107342
