ABSTRACT:
Waste parts made of synthetic resin and having a hydrolyzable coating thereon are crushed into chips. The chips are supplied quantitatively to a hydrolyzer apparatus where they are continuously transported through the hydrolyzer with a screw while in contact with steam so as to hydrolyze the coating. The chips with the hydrolyzed coating are dried in a drying furnace and the dried chips are transported to a kneader wherein the hydrolyzed coating is kneaded into chips. The kneaded chips are cooled and then pelletized into pellets in a pelletizing apparatus.
