OT: Plastic into oil

to make it worthwhile the machinery would really need to be wind, wave or solar powered. pointless using one non-renewable resource to convert another one back to something resembling its original state, when it should never have been used in the first place.

much better idea: stop using so much plastic. use and re-use glass. remember glass milk bottles? wash and re-use.simple idea, far less waste.

while I agree with this, it seems like this has the potential to be a less 'dirty' and destructive process of obtaining oil than say canadian tar sands. If we're on the down side of the peak oil bell curve (assuming you except that idea) then we can expect to obtain oil in very inefficient ways from now on anyway. but yes using less plastic is a better idea.
