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.

基于生命周期视角的上海市装修废弃物材料回收评价

在发展中国家，每年产生大量的翻新废物；然而，其收集、运输、处置和回收一直被忽视。中国最近启动了许多翻新垃圾的材料回收项目，有必要进行综合环境和经济评估，以选择处置设施。建立了五种潜在情景的生命周期评估，并对上海进行了技术经济评估。结果表明，全球变暖潜势、土地利用和细颗粒物形成对相关端点环境影响有显著贡献。此外，陆地生态毒性的外部成本是所有中点环境影响中最高的。技术经济评价结果表明，废弃物发电+ 再生骨料和再生砖生产+ 垃圾填埋是可选的最佳技术方案，可作为上海城市改造废弃物回收的可持续方法。本研究可望为发展中国家改造废弃物的可持续管理提供参考。

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.
