METHOD FOR COLLECTING COMPONENT MEMBER FROM USED ABSORPTIVE ARTICLE

To provide a method for efficiently collecting a component member from a used absorptive article without breaking the used absorptive article when the component member of the used absorptive article is recycled.SOLUTION: A method for collecting a component member from a used absorptive article 1 which has a surface sheet 2, a rear face sheet 3, and an absorber 4 arranged between the surface sheet and the rear sheet, where at least one of the surface sheet and the rear sheet contains a film as a component member and the absorber contains an absorber material as a component member. The method includes: a pretreatment step S1 of immersing the used absorptive article in water, and swelling the article; a decomposition step S2 of giving a physical impact to the swelled used absorptive article, and decomposing the used absorptive article into at least a film and an absorber material; and a separation step S3 of separating the decomposed film and the absorber material.SELECTED DRAWING: Figure 1 【課題】使用済み吸収性物品の構成部材をリサイクルするとき、使用済み吸収性物品を破断等せずに、使用済み吸収性物品から構成部材を効率よく回収する方法を提供する。【解決手段】本方法は、表面シート２と、裏面シート３と、表面シートと裏面シートとの間に配置された吸収体４と、を備え、表面シート及び裏面シートの少なくとも一方が構成部材としてフィルムを含み、吸収体が構成部材として吸収体材料を含む使用済み吸収性物品１から、構成部材を回収する方法である。本方法は、使用済み吸収性物品を水に浸して膨潤させる前処理工程Ｓ１と、膨潤した使用済み吸収性物品に物理的な衝撃を与えて、使用済み吸収性物品を、少なくともフィルムと吸収体材料とに分解する分解工程Ｓ２と、分解されたフィルムと吸収体材料とを分離する分離工程Ｓ３と、を備える。【選択図】図１
