ABSTRACT:
The present invention is intended to, from thermoplastic molded resin articles composed by a variety of laminating thermoplastic resin materials, separate, classify, select and recover the thermoplastic resin materials with classification in terms of type for reusing these materials. The process of the present invention comprises at least a step where laminated molded articles comprised by a variety of laminating thermoplastic resin materials are coarsely crushed into a plurality of small pieces to be treated; a step where impact type frictional crushing force is applied to said coarsely crushed small pieces 82 to be treated so that the above-mentioned small pieces 82 to be treated are peeled or separated, granulated or size-regulated, or pulverized with classification in terms of type; and a step where the resultant granulated or size-regulated particle-form thermoplastic resin materials 83 are selected so as to be particle-form thermoplastic resin materials 83a, 83b with classification in terms of type by means of rolling selecting or this rolling selecting and gravity selecting.
