Oh yeah -- I'm not saying it doesn't make sense, just that it wasn't something I ever thought about/understood. Kind in that weird "plastic melts so you can just melt it down and remold it, right?" mindset. Even though I do know that you can't do that for all plastics.

That said, what happens if you grind up + compress + heat those plastics? (it sounds like you understand this better than I do)
