Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for separating a decomposition product obtained by decomposing a plastic with subcritical water, which is high in filtration efficiency, and thus realize inexpensive separation. SOLUTION: The method is characterized by decomposing a plastic A containing an unsaturated polyester resin and an inorganic material with the use of subcritical water (process 1), and by filtrating the obtained decomposition liquid B at ≥40°C and ≤100°C to separate into a solution C, an inorganic filler and other solid contents D (process 2).
