Abstract

In recent years, there is an increasing interest in environmental friendly treatment of waste-plastics in terms of the generation of microplastics. Accordingly, the recycling of waste-plastics is very important because it provides advantages of volume reduction, mitigation of carbon dioxide emission, and reproduction of value-added products. In particular, in order to recycle the eco-friendly waste-plastics, it is necessary to use a physical separation methods, and among them, flotation separation, which can separate material (i.e., polymer component) in waste-plastics is well known as a very effective separation method in terms of material recycle. Therefore, in this review, the research trend of flotation separation for effective separation of mixture waste-plastics was investigated. In addition, through the reported research results, approaches to use as new functional materials from polymers, which are raw materials for waste-plastics, are summarized.

최근 미세플라스틱의 발생 측면에서 폐플라스틱의 친환경적 처리에 대한 관심이 증대하고 있다. 이에, 폐플라스틱의 재활용이 폐기물 간소화, 이산화탄소 배출 감소 및 부가가치 제품 재생산의 이점을 제공하기 때문에 매우 중요하다고 할 수 있다. 특히, 친환경적인 폐플라스틱의 재활용을 위해서는 물리적 선별방법을 통해야 하며, 그 중에서도 폐플라스틱내의 재질별 분리가 가능한 부유선별이 물질재활용 측면에서 매우 효과적인 분리방법으로 잘 알려져 있다. 따라서, 본 총설에서는 혼합 폐플라스틱의 효과적인 재질 분리를 하기 위한 부유선별의 연구 동향을 조사하였다. 추가적으로 보고된 연구결과들을 통하여 플라스틱의 원재료인 폴리머로부터 기능성 신소재로서의 활용에 대한 접근방법을 요약 정리하였다.
