초록

본 연구에서는 공동주택 단지에서의 음식물류폐기물을 수거 이송하여 대용량처리시설에 자원화 혹은 재활용하는 기존 방식과 발생지인 공동주택 내에서 처리하는 제안 방식을 가상하여 차량수거방식, 자동집하방식, 자동집하처리방식, 소규모분산처리방식, 오수처리연계방식으로 시나리오를 설정하고 각 시나리오별 초기 투자비용, 석유 사용량, 이산화탄소 배출량, 음식물류폐기물 처리 운영비용, 입주자 부담 관리비를 비교 분석하였다. 기존처리 방식에 비해 제안하는 소규모분산처리방식이 초기 투자비용, 연간 석유사용량, 이산화탄소 배출량이 가장 낮았으며 적용, 도입 가능성이 높았다. 음식물류폐기물 처리 운영비용은 기존 처리방식과 비교하여 1톤당 334,465원(약 91%)이 절감되며 세대 당 월 1,500원인 입주자 부담 관리비용 또한 902원으로 약 40% 절감이 가능하다고 분석되었다. 각 시나리오별 초기 투자비용과 석유사용량, 이산화탄소 배출량을 비교한 결과, 초기 투자비용이 낮은 처리방식이 연료 사용량과 이산화탄소 발생량도 낮은 경향을 나타내었다. 초기 투자비용과 석유사용량, 이산화탄소 배출량이 가장 낮은 시나리오는 소규모분산처리방식이며 가장 높은 시나리오는 오수처리연계방식이었다. 연구의 공간적 범위를 공동주택 단지로 설정할 때 소규모분산처리방식이 음식물류폐기물 제로화 모델로서 가장 적합한 방식으로 판단된다.

In this study, traditional treatment scenario of food wastes that collected and transported food waste is recycled in large treatment facilities and suggested treatment scenario of onsite zero discharge system that food waste is treated in housing complex were supposed. The scenarios were compared and analyzed by capital expenditure, oil consumption, $CO_2$ emission quantity, operating expenditure and management expenses. The capital expenditure, oil consumption and $CO_2$ emission quantity of small scale dispersion dealing method is the lowest compared to traditional treatment method. As a results, it is possible to obtain the effect that operating expenditure was reduced by 91% and management expenses was reduced by 40% with suggested treatment method. The treatment method that have low capital expenditure is tend to lower oil consumption and $CO_2$ emission quantity. The small scale dispersion dealing method have the lowest capital expenditure, oil consumption and $CO_2$ emission quantity and the linked method with sewage treatment have the highest expenditure and $CO_2$ emission quantity. Eventually, the optimal model of onsite zero discharge system in housing complex is small scale dispersion dealing method.
