Zusammenfassung: | To enable material recycling of a composite comprising resin sheets bonded with an adhesive.SOLUTION: A method for recycling an unused water-absorbing article as a composite includes: a dissolution step (step S1) for immersing an absorbent article (target 110) as a composite, comprising resin sheets 20 bonded with an adhesive, in a solvent 120, to dissolve the adhesive in the solvent 120; a separation recovery step (step S2) for separating and recovering constituent materials of the absorbent article (target 110) from which the adhesive has been dissolved and removed, such as the sheets 20, pulp fiber 11, and SAP12; and a drying step (step S3) for drying the separated and recovered constituent materials such as the sheets 20, the pulp fiber 11, and the SAP12.SELECTED DRAWING: Figure 2
【課題】接着剤で接合された樹脂シートを含む複合材のマテリアルリサイクルを可能とすること。【解決手段】複合材としての未使用の吸水性物品をリサイクルする方法は、接着剤で接合された樹脂シート20を含む複合材としての吸収性物品(被処理物110)を溶剤120に浸漬して接着剤を溶剤120に溶解する溶解工程(ステップS1)と、接着剤が溶解除去された吸収性物品(被処理物110)の構成材料であるシート20、パルプ繊維11、及びSAP12等を分離回収する分離回収工程(ステップS2)と、分離回収された構成材料のシート20、パルプ繊維11、及びSAP12等を乾燥する乾燥工程(ステップS3)とを具備する。【選択図】図2 |
