建筑工程垃圾减量化概况及评价标准探究

随着"无废城市"建设试点的确立，建筑垃圾的减量化和资源化利用成为工作重心。建筑垃圾可分为工程渣土、工程泥浆、工程垃圾、拆除垃圾和装修垃圾。重点介绍了国内建筑工程垃圾的组成与规模以及减量化策略与技术，并在建筑工程从设计到施工的建设全周期角度上，根据相关类似的评价标准创新性地提出了建筑工程垃圾的减量化评价标准。该评价标准可为未来行业标准的确立提供建议，助推"无废城市"试点建设。

A REVIEW ON REDUCTION OF CONSTRUCTION ENGINEERING WASTE IN CHINA AND EXPLORATION ON THE ASSESSMENT STANDARD

With the release of the "Zero-Waste City" pilot program, construction and demolition waste (C&D waste) has become a key issue for relevant local authorities. C&D waste can be technically classified into five categories: engineering sediment, engineering mud, engineering waste, demolition waste and decoration waste. This paper particularly reviewed the general situation of China’s domestic construction engineering waste, and discussed a diverse range of waste reduction techniques and strategies. It also proposed a novel assessment method for construction engineering waste reduction, which was developed upon a complete examination on the life cycle of a typical construction project. This assessment method could be of help in the future for potential establishment of relevant standards within the scale of nation, region or sector, and could ultimately work for the implementation of the "Zero-Waste City" pilot program.
