Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method and apparatus for recovering a foaming agent, capable of recovering the foaming agent in urethane foam of refrigerators and, at the same time, for reclaiming the urethane foam as a raw material for urethane resin by chemically decomposing the urethane foam in one extruder. SOLUTION: The apparatus for decomposing resin foam comprises a twin screw extruder having a vent-port for removing/recovering the foaming agent from refrigerator urethane foam. The method for decomposing resin foam comprises mixing and kneading the urethane foam with a decomposer to decompose into polyol of urethane resin raw material. COPYRIGHT: (C)2004,JPO
