초록
2004년 이후 EPR 제도의 시행과 더불어 폐플라스틱을 함유한 물질의 소각과 매립을 법으로 규제함에 따라 폐플라스틱 재활용의 필요성이 가중되고 있다. 본 연구는 생활계 폐플라스틱 재활용을 위한 정전선별 기술의 개발을 목적으로, 하전물질과 하전장치를 개발하여 선별효율을 높이고자 하였다. 따라서 우리는 대상 플라스틱의 하전효율과 재질분리에 적합한 하전장치 및 마찰하전형정전선별기를 개발하여 2종 혼합 플라스틱으로부터 PVC를 99% 이상 제거하였으며, PET와 같이 PVC 함량을 규제하는 경우 최적 실험조건에서 PET 회수율 80%로 PVC를 99.99% 까지 제거할 수 있는 기술도 개발하였다. 또한 3종 혼합 플라스틱은 98% 이상으로 분리하여 플라스틱의 재활용을 높일 수 있는 재질분리 기술을 확립하였다.
Abstract
The development of material separation technique for waste plastic recycling are the necessary situation restricted by law the reclamation and incineration of waste plastic after 2004, with enforcement of EPR (Extended Producer Responsibility) system. As the this study is the research on the development of electrostatic separation techniques for recycling of life circles waste plastic by development of charging material and charger, the separation efficiency can be improved. Therefore, we developed the charger and electrostatic separator to increase charging efficiency and material separation per object plastics, using these equipments, we removed PVC up to 99% from two kinds of mixed plastics. And in case of restricting PVC content such as PET, we developed the separation technique that can remove PVC up to 99.99% from PET with PET recovery about 80%. Also, as we separated over 98% for three kinds of mixed plastics, and then established material separation technique to increase recycling of plastic.
