ABSTRACT:
The present invention provides a process for recycling waste polymeric material comprising a mixture of waste polymeric material wherein the waste polymeric material includes from about 15 to 50 percent aliphatic polyamide material; granulating 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 of less than about the T.sub.g of the lowest melting waste aliphatic polyamide polymeric material.
