PROBLEM TO BE SOLVED: To provide a method for collecting a recycling material that can readily and efficiently sort out plastic used for components of a discarded vehicle and acquire a high-purity recycling resource.SOLUTION: A method for collecting a recycling material includes: a crushing step of dismantling and crushing a discarded vehicle to obtain a crushed matter; a plastic sorting step of irradiating the crushed matter with X-ray and detecting a constituent element of an inorganic filler contained in plastic 10 in the crushed matter to sort out the plastic 10 from the crushed matter; and a foreign matter removal step of removing a foreign matter from a surface of the plastic 10 sorted out in the plastic sorting step to recycle the plastic 10 from which the foreign matter is removed.SELECTED DRAWING: Figure 1 【課題】廃車の構成部品に用いられたプラスチックの選別を簡便かつ効率よく実施でき、純度の高いリサイクル資源を得ることが可能なリサイクル材料の回収方法を提供する。【解決手段】廃車を解体し破砕して破砕物を得る破砕工程と、破砕物にＸ線を照射し、破砕物中のプラスチック１０が含有する無機充填材の構成元素を検出して、破砕物からプラスチック１０を選別するプラスチック選別工程と、プラスチック選別工程で選別したプラスチック１０の表面の異物を除去する異物除去工程とを有し、異物が除去されたプラスチック１０をリサイクルする。【選択図】図１
