METHOD FOR TREATING AND RECYCLING PLASTIC, TREATED AND RECOVERED PLASTIC MATERIAL, AND RECYCLED PLASTIC

摘要

PPROBLEM TO BE SOLVED: To provide a method for treating and recycling a plastic, capable of improving the decomposition and/or solubilization speed while suppressing side reactions, and to obtain a treated and recovered plastic and a recycled plastic material. PSOLUTION: The method for treating the plastic is characterized by decomposing and/or solubilizing the plastic including a thermosetting resin in a solvent consisting of a phenolic compound as an indispensable component and containing a basic catalyst, in a supercritical or sub-supercritical state. A method for recycling the plastic is provided by decomposing the plastic by the above method and reusing the obtained treated and recovered material as the raw materials of the plastic. The recycled plastic material is provided by reusing the treated and recovered plastic as the raw material. PCOPYRIGHT: (C)2005,JPO&NCIPI
