Abstract

In developing countries, large amounts of renovation waste are generated annually; however, its collection, transportation, disposal, and recovery have long been ignored. China has recently initiated many material recovery projects for renovation waste, and it is necessary to conduct an integrated environmental and economic assessment to select disposal facilities. A life cycle assessment of five potential scenarios was established to conduct a techno-economic evaluation in Shanghai, China. The results indicated that global warming potential, land use, and fine particulate matter formation considerably contributed to the related endpoint environmental impacts. In addition, the external cost of terrestrial ecotoxicity was the highest of all midpoint environmental impacts. As a result, techno-economic evaluation showed that waste-to-energy + production of recycled aggregates and bricks + landfill is the best available technique among the scenarios, which could be used as a sustainable method for renovation waste recovery in Shanghai. This study is expected to provide a reference for the sustainable management of renovation waste in developing countries.

期刊介绍： Construction and Building Materials offers an international platform for sharing innovative and original research and development in the realm of construction and building materials, along with their practical applications in new projects and repair practices. The journal publishes a diverse array of pioneering research and application papers, detailing laboratory investigations and, to a limited extent, numerical analyses or reports on full-scale projects. Multi-part papers are discouraged. Additionally, Construction and Building Materials features comprehensive case studies and insightful review articles that contribute to new insights in the field. Our focus is on papers related to construction materials, excluding those on structural engineering, geotechnics, and unbound highway layers. Covered materials and technologies encompass cement, concrete reinforcement, bricks and mortars, additives, corrosion technology, ceramics, timber, steel, polymers, glass fibers, recycled materials, bamboo, rammed earth, non-conventional building materials, bituminous materials, and applications in railway materials.
