Zusammenfassung:	To provide a method for separating a function-applying layer from a thermoplastic resin molded body having the function-applying layer to simply recover the thermoplastic resin molded body.SOLUTION: A method for recovering a thermoplastic resin molded body separates a function-applying layer from the thermoplastic resin molded body by hydro-thermally treating the thermoplastic resin molded body having the function-applying layer under a pressure of 101 kPa or higher and under a temperature condition where a softening point of a thermoplastic polymer forming the thermoplastic resin molded body is ± 30°C.SELECTED DRAWING: None 【課題】機能付与層を有する熱可塑性樹脂成形体から機能付与層を分離して熱可塑性樹脂成形体を簡便に回収する方法を提供する。【解決手段】機能付与層を有する熱可塑性樹脂成形体を、１０１ｋＰａ以上の圧力下、熱可塑性樹脂成形体を形成している熱可塑性ポリマーの軟化点±３０℃の温度条件で、水熱処理することにより、機能付与層を熱可塑性樹脂成形体から分離させる、熱可塑性樹脂成形体の回収方法。【選択図】なし
