There's already the beginnings of converting plastic back into petroleum. It'll be the end of having to sort the plastics by type. It works for sure in the lab. From there, it can be made into plastic again. I was bummed that the scientist mentioned that it could even be turned into fuel. I would love to email him this page. That's part of why the title of the meme starts with, "Burning gasoline is bad, M'kay?"
