Abstract
There is provided a method for solubilizing cross-linked EVA which can dissolve cross-linked EVA within a short time such as about 60 minutes. Further, an object of the present invention is to provide a recovering method which uses such a solubilization method to solubilize, within a short time, the cross-linked EVA of a solar battery module containing metal and silicon and recovers valuable resources such as metal and silicon, and the recovering method includes treating the cross-linked EVA with a treatment solution at a temperature within a range from 100 to 300° C. consisting essentially of a solvent selected from an alkyl-based alcohol having 5 to 12 carbon atoms and a phenol and an additive selected from an alkali, an oxoacid, and an oxoacid salt, to recover resources such as metal and silicon.
