How to Recycle Plastics

Superglue doesn't stick well to certain kinds of plastics, like polyethylene or polypropylene. The polymer that's formed from superglue will reverse if you heat it past a certain temperature.

And then the even harder question is, could we do that in the presence of a really contaminated dirty mixture of other plastic waste?"
