Recovery of mixed plastic materials

In a method for recovering mixed plastic materials from refuse selected from the group consisting at least of polyvinyl chloride and polyethylene, comprising grinding the mixture of plastic materials into small particles, extruding the ground mixture and granulating or molding the extruded material, the improvement comprising ballistically sorting the ground mixture in order to adjust the composition of the mixture and adding to 100 parts of said ground mixture a regenerating master mix comprising:

• ______________________________________ rongalite 0.1 to 5 parts [-chlorinated polyethylene 0 to 20 parts] polyvinyl chloride stab- ilizer 0.1 to 5 parts lubricant 0 to 5 parts expanding agent 0 to 4 parts shock resistant ABS or MABS 0 to 12 parts ground polyvinyl chloride or polyethylene 0 to 30 parts filler 0 to 800 parts plasticizer or gelling agent 0 to 70 parts ______________________________________
• and an amount of chlorinated polyethylene sufficient to bind the polyethylene to the polyvinyl chloride comprising up to 20 parts per 100 parts of the ground mixture, wherein the rongalite prevents the hot glueing effect due to the presence of milk or similar products in said refuse.
