polylactide, a bioplastic
So it does exist, and is cheap enough to use in teabags. Why not use it more, to pack vegetables snd stuff?
That kind of bioplastic tends not to biodegrade naturally, instead requiring a heated industrial composter with specially engineered enzymes added. If it’s disposed of properly, it’s great, otherwise it’s no better than traditional plastic but costs more. Also, not all bioplastics biodegrade at all as all the word means is that the source material is biomass rather than oil.
So even if you burn it with the trash, the C goes back to the natural cycle, instead of additional C we pump out of deposits of warmer times, we make plastic off. Still sounds better to me.
