Plastic Pelletizer

With all the recycling going on, and the difficulty in recycling plastics, I was thinking that what every home needs is a plastic pelletizer. You dump whatever old plastic items you have in the top, the machine munches, mashes, heats, and eventually beats all the plastic into little pellets, which it deposits in a bucket. When the bucket is full, you put it out on the curb with all your other recycling.

This machine would take all your old plastic items: milk jugs, yogurt tubs, cellophane plastic wrap, old CD cases, shrink wrap, whatever. Grind them up and melt them into a plastic goo and then extrude this goo into little plastic pellets.

I am sure there are numerous problems with making this idea into a real device, but I as an idea, I really like it.
