Abstract

In this paper, we tried to examine the composition ratio of plastic waste from households according to the generated city and the qualities according to the production time of material recycling products. As a result, the composition ratio of recyclable plastic waste among the total plastic waste according to the generated cities is 64.5~90.4%, showing a big difference by city. In addition, the quality evaluation of material recycling products by production time for four months showed that the average tensile strength was 12.33MPa, the average elongation rate was 5.94%, the average density was 1.35g/㎤ and the average ash content was 3.66%.

다양한 복합재질 생활계 폐플라스틱의 물질재활용 확대를 위해서는 물질재활용 제품의 용도개발 및 이들의 품질 안정성 확보 노력이 필요하다. 본 논문에서는 생활계 폐플라스틱 물질재활용 제품의 품질에 대한 안정성을 확보하기 위한 기초 연구로서 발생지역에 따른 생활계 폐플라스틱의 혼입율 특성 및 이를 활용한 물질재활용 제품의 생산시기에 따른 품질특성을 비교 검토하였다. 그 결과 발생 도시에 따른 생활계 폐플라스틱 중 재활용 가능한 폐플라스틱의 구성비율은 64.5~90.4%로서 도시별 큰 차이를 보이고 있다. 또한 4개월간 생산시기별 물질재활용 제품의 평균 인장강도는 12.33MPa, 평균 연신율은 5.94%, 평균 밀도는 1.35g/㎤, 평균 회분은 3.66%인 것으로 나타났다.
