초록

생분해성 플라스틱을 포함하는 유기성 도시생활쓰레기(OFMSW)의 퇴비화 연구를 준생산용 규모 퇴비화 장치를 이용하여 행하였다. OFMSW는 실제 도시생활쓰레기 구성비에서 무기물을 제외하고 유기성 물질만을 혼합하여 사용하였고, OFMSW를 구성하는 각각의 물질에 대한 생분해도를 ISO 14855법으로 측정하였다. 또한, 퇴비의 화학적 물리적 특성도 조사하였다. 구성 물질의 생분해도 분석 결과, 생분해성 고분자를 포함한 각 물질 모두 퇴비화에 충분한 생분해도를 보였다. 또한 OFMSW로부터 유해하지 않은 퇴비를 얻을 수 있음을 알았다.

The composting study of organic fraction of municipal solid waste (OFMSW) containing biodegradable plastic was performed by using a pilot scaled composting apparatus. OFMSW was artificially prepared for composting. The composition of artificial OFMSW was the same as that of real MSW excluding inorganic waste. The biodegradability of individual component of OFMSW was studied according to the ISO 14855 method. The chemical and physical characteristics were also observed. Biodegradability study revealed that every component of OFMSW, including biodegradable plastic, had sufficient degradability for real composting. And it was found that non-toxic compost can be produced from OFMSW containing biodegradable plastics.
