Abstract

In general, recyclable items are separately discharged from households and then, hand-sorted into different types of valuables at materials recovery facilities (MRF). However, most of residues after hand-sorting are finally end up with landfill and/or incineration due to lack of separation technologies and economical reasons. In the present study, physical properties on recyclable items obtained from an MRF are investigated to improve the recovery of valuable items. The results of physical compositions based on the sizing tests are also presented.

일반적으로 재활용대상 폐자원은 가정에서 분리 배출된 후 재활용선별장에서 수선별에 의해 유가자원으로 회수된다. 그러나 기존의 재활용선별장에 반입되는 폐자원의 경우 성상이 매우 다양하고 복잡 할 뿐만 아니라 이물질의 함량이 높아 기존의 회수방법으로는 선별효율이 매우 낮은 실정이다. 따라서 선별장에서 재활용품 회수 후에 발생되는 잔재물은 대부분 매립 또는 소각되고 있어서 그로인한 2차환경오염 및 잔류물로부터 추가적인 유가자원의 회수는 시급히 해결해야 할 문제이다. 본 연구에서는 재활용선별장에 반입되는 폐자원에 대한 성상조사를 실시하여 폐자원의 발생특성 변화를 파악하였으며, 전처리시설의 효율성을 증대시키기 위하여 입도분석을 통하여 향후 재활용 선별시설 구성의 기초자료를 제공하였다.
