Status Analysis of Building Construction and Demolition Waste Treatment/Disposal and Management in China

China is experiencing a large scale of building construction, attracting great attention paid to debris generated by frequent construction and demolition activities for its cost inefficiency and environmental pollution. It is of great importance to better understand the magnitude and composition of the waste stream when developing rules, policies and strategies to manage this segment of the solid waste. In this study, after clarifying the definition of construction and demolition (C&D) waste according to its complex composition and diverse sources, approaches quantifying C&D waste to meet different requirements were summarized, and a simple weight-per-construction-area was employed to make an approximate estimation. Based on the main causes and status quo of C&D waste management, measures to reduce C&D waste were proposed to realize a sustainable construction industry, which include improving envirotunental awareness, strengthening the establishment of policy system and company waste management system, and reinforcing research and study work. This study also adds to the knowledge on research trend of C&D waste in China.
