초록
미세플라스틱은 매우 중요하고 심각한 환경 문제로 인식되어, 전세계적으로 관심이 증대하고 있다. 플라스틱은 저렴한 가격, 경량성, 우수한 가공성, 다양한 재질별 특성을 가지고 있어 산업이 발전함에 따라서 생산량과 폐기량 또한 급격하게 증가하고 있다. 특히, 최종적으로 해양 환경으로 유입되어 생태계에 큰 영향을 줄 것으로 예상하고 있어, 이에 대한 처리가 매우 시급한 문제이다. 그러나 작은 입자크기와 함께 존재하는 환경이 다양하기 때문에 일반적인 처리방법의 적용이 어려워 다양한 분야에서 많은 연구가 진행되고 있다. 특히, 기존에 광물을 처리하는 선광공정 중 비중, 자력, 정전선별 등의 방법을 미세플라스틱의 처리에 적용하는 연구가 다수 진행되고 있으나 아직 실험실 단계이기 때문에 효율적인 처리를 위한 선별기술의 개발이 시급한 실정이다.
Abstract
Microplastics are recognized as critical and serious environmental problem in worldwide. Plastics are inexpensive, lightweight, excellent in processability, and various in material-specific properties. Along industrial development, the production and disposal amount of plastics are also rapidly increasing. In particular, abundant plastic wastes are eventually disposed into marine environment with harmful impacts on the ecosystem. Therefore, lots of relevant studies were recently progressed in various fields. However, many studies are being just conducted due to its difficulty in applying a general treatment method for those small particle sizes and their various characteristics. In the meantime, lots of researches are being conducted on applying methods using physical properties such as specific gravity, magnetic, and electrostatic separation, which are beneficiation processes of minerals. However, since it is still in the laboratory stage, the development of larger scale separation technology for efficient treatment is urgent.
