<p><P>PROBLEM TO BE SOLVED: To provide a method of efficiently decomposing a composite material including a resin component and inorganic materials at low cost. <P>SOLUTION: The composite material including a resin component and inorganic materials is broken up, then separated into a broken resin mainly containing the resin component and broken inorganic materials mainly containing inorganic substances according to the differences in density, morphology, electric properties and water-wettability, and then the broken resin materials are subjected to decomposition treatment with a solvent in a super- or sub-critical state. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
