Abstract
Waste newspapers was used as an amendment to adjust the moisture of household food wastes for composting. The mixture of household food wastes and waste newspapers was composted in an especially designed small home composter, where the early fed composting materials were discharged early. The temperature inside composting materials was influenced very much by that of outside, because the composter was not insulated. Accordingly, the higher the outside temperature was, the higher the decomposition rate was. The temperature inside composting materials did not reach to optimum, because the amount of composting materials added in the composter everyday was too little, and it caused too high water content of discharged compost after 15 weeks. Therefore, it was required that the composter must be insulated to maintain the higher temperature. The inorganic compounds
단열이 되지 않은 소형 퇴비화용기를 이용하여 가정에서 발생되는 폐기물 중 종이류를 제외한 퇴비화 가능한 폐기물은 퇴비화하였다. 수분 조절제로서 가정에서 발생되는 폐 신문지를 사용하였다. 초기 퇴비화 혼합물질이 투입되기 시작하여 15주 후에 배출되었다. 실험 결과를 요약하면 다음과 같다 : 퇴비화용기가 단열재로 보온되지 않아 외부 온도의 영향을 크게 받았다. 따라서 퇴비화 후 건조물질 기준으로 분해 율은
