<p><P>PROBLEM TO BE SOLVED: To provide a method and an apparatus for efficiently separating a polyurethane resin and a thermoplastic resin from a mixture containing a lightweight material of the polyurethane resin and a lightweight material of the thermoplastic resin. <P>SOLUTION: The method for recovering the resin material includes a step for reacting a polyurethane resin-decomposing agent with the resin mixture containing the polyurethane resin and the thermoplastic resin by using a decomposing mechanism 10 to reduce the molecular weight of the polyurethane resin and to afford a decomposed mixture containing the polyurethane-decomposed product having≥50°C softening point, a step for pulverizing the decomposed mixture containing the polyurethane-decomposed product and the thermoplastic resin obtained in the step by using a pulverizing mechanism 20, and a step for separating the pulverized product of the polyurethane-decomposed product and the thermoplastic resin by using a separation mechanism such as air separation. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
