PCT No. PCT/JP93/01121 Sec. 371 Date Feb. 16, 1996 Sec. 102(e) Date Feb. 16, 1994 PCT Filed Aug. 10, 1993 PCT Pub. No. WO94/03323 PCT Pub. Date Feb. 17, 1994.The present invention relates to a process for recovering recyclable expanded particles from expanded particle moldings including expanded particles of a synthetic resin coated with thermoplastic resin (interfacial material) whose melting point is lower than that of the synthetic resin of the expanded particles or whose solubility is different from that of the synthetic resin of the expanded particles. The process includes the steps of softening or melting the interfacial material by heating or dissolving it with a solvent, and separating the expanded particle molding into individual particles by applying a shearing force thereto under circumstances such that the bond strength among the expanded particles in the molding is weakened.
