The present invention relates to chemical recycling using by-products and wastes of thermosetting polyurethane resins, and an object thereof is to thermally polymerize by-products generated from polyurethane production sites, household wastes, refrigerator wastes, etc., and reuse them as polyols, which are polyurethane raw materials. To do it.n n n Thermally curable waste is a polymer product that cannot be easily recycled by remelting, and it is expected to be economically improved in terms of waste disposal and improved biodegradability by thermally depolymerizing and reusing it. |
