breaking down plastics

Here's another team working on how to break down polypropylene and polyethylene using a catalyst - relatively cheap materials - to break the polymer chains. 

So far, they've had some success in a test environment. It will be interesting to see if they can try it out on a large scale and see what the effects are, and whether this could be scaled.
