Abstract

본 연구에서는 자원화 가능한 폐기물의 양이 분석되었으며, 폐기물 자원화시설을 단독 또는 광역시설로 추진할 경우의 설치비 및 운영비를 산정하고, 매립비용과 비교, 분석함으로서 자원화시설의 타당성을 검토하고자 하였다. 자원화시설로는 고형연료화(RDF) 시설과 자원회수시설(소각)에 대한 검토를 수행하였다. 그리고, 강원도 각 시 군별 생활폐기물의 발생량과 가연성 폐기물의 비율을 고려하여 비용분석을 위한 광역권역을 설정하였다. 분석 결과, 단독시설의 경우에는 RDF 및 자원회수시설(소각) 모두 매립방식에 비교하여 경제적 편익이 없는 것으로 나타났다. 광역 시설의 경우, RDF 방식은 매립방식에 비해 많은 비용을 절감하는 것으로 나타났지만, 자소각 방식은 그렇지 않은 것으로 나타났다. 경제적 편익과는 별개로 화석 연료의 고갈, 지구온난화, 환경적 위해성, 그리고 사회적 갈등 등을 고려할 때 폐기물의 자원화는 중요하게 고려되어야 한다. 특히, 향후 CDM 사업이 활성화될 경우 CERs(온실가스 저감인증)에 의한 추가적인 경제적 부가가치도 기대할 수 있을 것으로 나타났다. RDF 시설에 의한 CERs는 약 2,565억원, 자원회수시설에 의한 CERs는 약 540억원(단독시설) 및 774억원(광역시설)으로 분석되었다. In this study, the amount of waste resource that could be recovered was analyzed. The installation and operation costs of waste resource recovery for both single- and multi-regional facility were calculated, and compared with the costs of landfill to investigate the feasibility of them. RDF(Refuse Derived Fuel) process and resource recovery by incineration process were considered as waste resource recovery facility. And, the multi-regions for cost analysis were established on the basis of the proper generation rate of municipal waste with the consideration of combustible ratio. The study results showed that single region facility for both RDF and incineration process has no economic benefit, compared with the landfill method. For the multi-regional facility, RDF process could save a large cost than the landfill method, but the incineration facility couldn't. Separate from the economic benefits, the waste resource recovery should be importantly considered when considering the depletion of fossil fuel, global warming, environmental toxicity, and the enormous expenses due to social conflict and confuse. When the CDM(Clean Development Mechanism) is vitalized in the near future, the additional economic benefits by CERs(Certified Emission Reductions) could be expected. CERs for RDF facility is corresponding to about 256.5 billion won, and CERs for incineration facility is corresponding to about 54 and 77.4 billion won for single- and multi-regional facility, respectively.
