METHOD FOR RECOVERING EFFECTIVE COMPONENT FROM POLYESTER WASTE

摘要

PROBLEM TO BE SOLVED: To provide a method for recovering an available component efficiently and economically so as to make it possible to obtain a recovering monomer of high purity and enhance a handling of fibrous flocks as to the method for recovering the available component from polyester waste containing impurities. SOLUTION: A pretreatment process which enhances a handling by removing a waste when the waste is decided to be the waste other than polyester according to an examination by a distincting apparatus and grinding and granulating the waste passing the examination, is performed. Thereafter a method for recovering a recovering monomer of high purity can be performed easily and economically by providing a reaction process including a removing process of impurities by physical and chemical treatment.
