description PROBLEM TO BE SOLVED: To remove urethane resin from resin composite including the urethane resin and polypropylene resin by dissolving the urethane resin and recover the polypropylene resin containing no urethane resin efficiently at a low cost, thereby improving economical efficiency and productivity.SOLUTION: A dissolution device 1 includes: an injection means 2 for injecting the resin composite including the polypropylene resin and the urethane resin; a dissolution tank 3 storing therein treatment liquid 11 for dissolving the urethane resin in the injected resin composite; and a separation recovery means 4 for separating the insoluble polypropylene resin from the treatment liquid 11 having the urethane resin dissolved therein and discharged from the dissolution tank 3 and recovering the polypropylene resin.
