ABSTRACT:
The particulate waste is mixed with plastic waste in a screw extruder, pressed and extruded. The particulate waste and plastic waste are introduced into the feed hopper of a screw extruder. The components introduced are intimately mixed in the screw extruder by the rotating screw(s) and firmly compressed. The pressure in the mixture may be up to 100 bar. The particulate waste is bound in the plastic in a way that prevents any further contact with the environment.
