I'm sure there must be some way to break down plastics and render them harmless. Could it be that the people who could do this just don't want to? I mean I know they can just burn it, I have burnt plastic bags and bottles and I see nothing left, OK the fumes might be harmful but this could be done in some place where it doesn't hurt anyone, like a desert, but I guess there must be a more environmentally friendly and cheap way to get rid of it.
