The huge generated amounts of construction and demolition (C&D) waste around the world, which amounts up to more than 25% of the total generated waste, has become a serious environmental challenge that needs to be addressed. This analytical review paper sheds light on the different adverse environmental impacts of the presently used conventional management method of landfilling and proposes waste recycling as an alternative sustainable management option. Analysis showed that C&D waste recycling could be an effective mitigation option to reduce the risk of landslides; reduce the energy consumption; offset the greenhouse emissions where about 39% is attributed to the construction industry; recover added-value materials; create jobs; and protect the earth’s natural resources. The results of analysis highlight the importance of on-site recycling and segregation at source for offsetting the greenhouse gas emissions as well as mitigating the risks of the hazardous portion. The results of this analytical review promote the importance of diverting construction and demolition waste from landfill sites to recycling and help decision makers to adopt the recycling option to achieve sustainable development.

建筑废料的回收利用及其对气候变化和可持续发展的影响

全世界产生的大量拆建废料(C&D)占废料总量的25%以上,已成为严重的环境挑战,需要解决。这份分析性综述文件揭示了当前使用的传统填埋管理方法对环境的不同不利影响,并提出了将废物回收作为可持续管理的替代选择。分析表明,拆建废料的回收可能是减少滑坡风险的有效缓解方法。减少能源消耗;抵消了约39%的温室气体排放来自建筑业;回收增值材料;创造就业机会;并保护地球的自然资源。分析结果突显了从源头进行现场回收和隔离对于抵消温室气体排放以及减轻危险部分风险的重要性。这种分析性审查的结果提高了将建筑和拆迁废物从垃圾填埋场转移到回收中的重要性,并帮助决策者采用回收方案以实现可持续发展。
