초록

본 연구는 S시 S구의 재활용품 배출특성을 조사 및 분석을 통해 재활용품 선별장에서 재활용품 선별율을 조사하였다. 재활용품 배출특성을 조사하기 위해서 발생원, 수집운반, 선별단계별로 나누어 분석하였다. 분석결과, 재활용품의 발생량 원단위의 전체 평균은 0.121kg/일 인, 지역별 재활용품의 수거주기는 보통 주3회(월수금 혹은 화목일)로 나타났으며, 차량별 혼합재활용품의 밀도는 평균 $202.4kg/m^3$로 나타났다. 선별단계에서의 현황분석을 진행한 결과, 혼합재활용품의 반입량은 평균 1,154.6톤/달, 겉보기밀도의 평균은 $181kg/m^3$, 선별재활용품의 양은 평균 448.5kg/달, 잔재물의 밀도는 $48kg/m^3$으로 나타났다. 선별장으로 입고된 혼합재활용품에서 유가품 선별율은 약 38.85%이며 잔재물은 약 55.90%로 나타났다. 전체 잔재물 7,744.8톤 중 유가품은 약 4,272.1톤이 존재하는 것으로 나타났다. 활용가능한 유가품의 수거효율을 높이기 위한 방안으로는 거점수거 활성화, 선별시설 자동화 및 현대화, 잔재물의 자원화 등이 검토되었다.

This study was conducted to investigate and analyze the discharge characteristics of recyclable material from S-city, S-district, in order to improve the sorting efficiency in recycling sorting facility. The characteristics of recyclable materials collected were analyzed in three different scopes; source origin, collection and transportation, and sorting steps. The average of recyclable waste generation is $0.121kg/day^*man$. Regional collection period appears to be three times a week, and the density of mixed recyclable wastes showed the average of $202.4kg/m^3$ in the waste collection vehicle. In the analysis into the sorting steps, the average of carrying amount of mixed recycling products is 1,154.6 ton/month, the average of appeared density is $181kg/m^3$, the average amount of separated recycling products is 448.5kg/month, and the density of recycling residue is found out to be $48kg/m^3$. The sorting rate of recyclable material is 38.85% and the percentage of residues is 55.90%. Out of 7,744.8 tons of the total recyclable residues, 4,272.1 tons were found out to be possible recylable materials. As a result of increasing the recycling rate of residues, the encouragement of base-recycling, the automation and retrofit of sorting equipment, and energy recovery from recycling residue were discussed.
