Abstract

본 발명은 재질이 상이한 복수의 층들을 가지는 복합필름의 각 층을 각각 박리 내지 분리시켜 별개로 회수하는 방법 및 장치의 제공에 관한 것이다.
본 발명에 따르면, 재질이 서로 다른 복수의 층들을 가지는 복합필름을 복수의 피처리 소편들롤 세단하는 공정 및 수단과, 상기 세단된 개개의 피처리소편에 대해 충격마쇄력을 부가하여 상기 피처리소편을 구성하는 층들을 각 층별로 박리 내지 분리하는 공정 및 수단이 제공된다. 상기 박리ㆍ분리공정을 거쳐 회수된 처리물은 이에 풍력선별공정이 가해져서 혼재상태로 회수된 각 층들이 개별적으로 선별 회수된다.
