고품질 재생플라스틱 원료 생산을 위한 자동화 설비 기술 개발

Abstract

Most of the companies that produce recycled plastics in Korea are small companies, and technology research is rarely conducted. Therefore, only waste plastics that are relatively clean or in good condition are recycled. In order to increase the physical recycling rate, it is necessary to develop an automated facility technology that can produce high-quality recycled plastic raw materials from waste plastics containing a large amount of foreign substances including heavy metals. In this study, we developed, built, and produced an automated facility that can produce high-quality recycled plastic raw materials from waste plastics containing a large amount of foreign substances including heavy metals. In order to evaluate the produced recycled plastic raw material, heavy metal content evaluation, chlorine content evaluation, and tensile strength evaluation were performed, indicating that it was a high-quality recycled plastic raw material. In addition, it was shown that automated facilities capable of producing high-quality raw materials can recycle more waste plastics than facilities before development.
