ABSTRACT:
The present invention provides for an improved process for recycling waste polymeric material comprising a mixture of waste polymeric material wherein the waste polymeric material includes from about 0 to 40 percent aliphatic polyamide material; granulating and densifying the chopped mixture into fragments at least about 100 times smaller than the size of the waste polymeric material; and extruding the ground mixture at a temperature that does not exceed the temperature at which the largest portion of polymer based material decomposes.
