Abstract

This study aims to anal yze the social benefits of introducing a sel ective demol ition system for buil dings. Incremental revenue, incremental cost, and incremental profit for the entire nation were derived based on the calculated costs and revenues of selective demolition for a 2,400 m2 apartment complex. In conducting selective demolition on a 2,400 m2 building, the increase in demolition construction costs, the reduction in waste disposal costs due to the decrease in mixed waste, and the revenue obtained from recycling separated and sorted waste were comprehensively reviewed. It was calculated and analyzed that, compared to general demolition work, a total cost-saving effect of 34,727,000 KRW could be expected. Extrapolating this to the entire nation, based on the year 2020, which had the highest construction waste generation, it is estimated that the social benefits would amount to 746,782,886,000 KRW.

이 연구에서는 건축물 분별해체 제도 도입에 따른 사회적 편익을 분석하고자 하였다. 이를 위하여 연면적 2,400 m2의 공동주택을 대상으로 산출된 분별해체 수익 및 비용을 토대로 국가전체의 증분수익, 증분비용, 증분이익을 도출하였다. 2,400 m2를 대상으로 분별해체 공사를 실시할 경우, 해체공사 시공비용의 증가액, 혼합폐기물의 감소로 인한 발생 폐기물 처리 비용 저감액, 분리·선별한 폐기물을 활용한 재활용으로부터 얻을 수 있는 수익을 종합적으로 검토하였을 때, 일반 해체공사와 비교하여 총 34,727천원의 비용 절감 효과가 예상됨을 확인할 수 있었다. 이를 건설폐기물 발생량이 가장 많았던 2020년을 기준으로 국가 전체적으로 환산한다면 746,782,886천원의 사회적 편익이 발생함을 추정할 수 있었다.
