Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a method for recovering insoluble matter from a composite, which can improve economic efficiency and productivity without lowering characteristics of recycled products, by a method for recovering the insoluble matter from the composite containing a resin cured product and the insoluble matter without requiring a labor hour and a cost in a treatment of washing wastewater.SOLUTION: A method for recovering insoluble matter from a composite containing a resin cured product to be dissolved by at least a treatment liquid and the insoluble matter not to be dissolved by the treatment liquid includes a feed step of feeding the composite to a dissolution tank, a dissolution step of dissolving the resin cured product by the treatment liquid composed of an organic solvent and a catalyst stored in the dissolution tank, a solid-liquid separation step of separating the treatment liquid containing the resin cured product dissolved in the dissolution step from the undissolved insoluble matter, a recovery step of recovering the insoluble matter, a cleaning step of cleaning the insoluble matter with the organic solvent without using water and a drying step of drying the cleaned insoluble matter. |
