Urban mining in buildings for a circular economy: Planning, process and feasibility prospects

• A feasibility assessment method has been developed for urban mining in buildings. Demolition sites were investigated feasibility, skills and costs. Significant economic saving reuse benefits exist building components recovery. Experiments provide evidence rapid enhancement of salvage workers. The construction industry remains under immense pressure to reduce its material climate related impacts. Increasing demand reduced lifetimes have therefore motivated efforts Even though projected as a crucial measure improving resource efficiency, adoption practice the at very symbolic stage. Upscaling secondary recovery sector requires further understand from perspective project timelines, time, Hence, this study develops an empirical research approach applies it demolition-ready residential buildings stock Singapore with semi-skilled It indicators based on planning stages, process change, behavioural practices reuse-driven considerations. Based over 350 34 categories, results show average 1 12 min time estimated cost S$0.8 S$9 per component. Further, regulatory requirements demolition permits can sufficient without affecting timelines. workers seem important, highlights significant improvement repeated specific components. Results also robust case prospects embodied carbon savings. Overall, contribute net-zero targets mitigation greater multi-stakeholder involvement market push sector.
