ABSTRACT

This study focuses on Xining City as a case study to analyze the current status and challenges in construction waste management. Using material flow analysis, the research examines the entire process of construction waste from generation, treatment to final disposal in Xining, aiming to evaluate resource utilization efficiency and identify key issues. The analysis reveals that the comprehensive utilization rate of construction waste in Xining City is only 15.3%, with 83.1% of waste directly landfilled, indicating a low level of resource recovery. Further analysis from government, enterprise, and societal perspectives highlights systemic issues in the current management framework, including inadequate policy enforcement and supervision, outdated technologies and insufficient production capacity in recycling enterprises, as well as weak public participation awareness. Xinings construction waste management remains at a preliminary stage dominated by end-of-pipe disposal. There is an urgent need for systematic improvements through enhanced policy coordination, technological innovation, and market cultivation to accelerate the establishment of a circular economy model.
