Abstract

In this study, as a foundational research aimed at promoting the efficient recycling and environmentally friendly disposal of construction waste through the activation of a selective dismantling system, our primary objective was to analyze the economic feasibility of implementing selective dismantling. To achieve this, we conducted an assessment on a 5-story residential building with a construction area of 2,400 m2 as a case study. When considering the additional cost of dismantling construction ① the reduction in waste disposal costs due to decreased mixed waste, ② and the potential revenue from recycling through the separation and sorting of waste materials, and ③ we were able to comprehensively confirm that there is an expected cost-saving effect totaling 34,727,000 KRW when compared to conventional demolition methods.

이 연구에서는 건설폐기물의 효율적인 재활용과 친환경 적정 처리를 위한 분별해체 제도의 활성화를 위한 기초연구로써, 우선적으로 분별해체 적용을 통한 경제적인 효용성을 분석하고자 하였다. 이를 위하여 5층 높이의 공동주택 1동의 공사면적 2,400 m2 를 대상으로 분별해체 공사를 실시할 경우, ① 해체공사 시공비용의 증가액, 혼합폐기물의 감소로 인한 ② 발생 폐기물 처리 비용 절감액, 분리·선별한 폐기물을 활용한 ③ 재활용으로부터 얻을 수 있는 수익을 종합적으로 검토하였을 때, 일반 해체공사와 비교하여 총 34,727천원의 비용 절감 효과가 예상됨을 확인할 수 있었다.
