Abstract1   본 연구는 경제성 측면에서 건축물 구조를 고려하여 해체폐기물의 재활용가능성에 대한 연구를 수행하였다. 이를 위해 건축물 폐기단계 각 세부활동별 비용산출 방안을 제시하고 인벤토리 분석 수행하였으며 그리고 해체폐기물의 재활용에 따른 경제적 가치를 산출하였다. 이를 토대로 최종적으로 건축물의 구조와 해체폐기물 종류별 재활용가능성 결과를 제시하였다.
Abstract2   This study investigates the recycling potential of demolition waste (DW) according to building structure, while considering economic aspects. For that, this study surveyed 1,034 residential buildings to collect reliable information on demolition waste generation rates (DWGRs). This study suggested a method for operational cost calculation for each stage and carried out an inventory analysis. The economic value of recycled DW materials was also calculated. And then, the recycling potential(RP) was calculated by building structures and waste types. RP by building structure was low (27-40%), and RP was found in the order of masonry-block, wooden, RC and concrete-brick. By type of DWs, the RP of aggregates was considerably lower than 7%, and DWs such as wood, plastics, and metals showed more than 100% RP. Considering the results of this study, In order to improve the RP of buildings and DWs, the diversification of products that recycled waste like aggregates (i.e., mortar, concrete, bricks, blocks, tiles) and the development of high value-added products are considered to be the most urgent problems. Based on the above RP results, this study proposed a more advanced method for life cycle assessment of buildings and demolition waste.
