Until someone develops some sort of multi-spectral imaging that can reliably sort plastic based on it's composition there's little hope of recycling plastic. And then you still need different enzymes that can break down different compositions. It's sad, but realistically almost all plastic one disposes of needs to go in the trash can rather than recycling. You can't even rely on dedicated collection - https://abcnews…
Funny you phrase it like that, because that's exactly what the STEINERT UniSort does. Plastic waste is finely shredded, dumped onto a conveyor belt, imaged, then passed over air puff sorters: https://www.youtube.com/watch?v=M3QHa9oQshw
Is it worth it? Of course not. Far cheaper and easier just to burn it. But for EU nations that are really dedicated to recycling, it can be done.
