A Framework to Evaluate the Construction and Demolition Waste Management Efficiency: Based on the City Level

The problem of construction and demolition waste (C&D waste) is becoming more and more prominent, which has attracted the attention of various countries and cities. Due to the different development speeds of various cities, there are also differences in the generation and disposal of C&D waste, which to some extent leads to uneven management levels of C&D waste in different cities. At present, there is still a lack of a framework to evaluate the effectiveness of C&D waste management at the city level. To make up for this gap, the study, through desktop surveys and brainstorming methods, based on three dimensions of C&D waste whole-process management, security system construction, stakeholder participation and sense of gain, a set of C&D waste management efficiency evaluation indicators consisting of 9 first-level indicators and 31 s-level indicators was established. The first-level indicators include source control of C&D waste, transportation management, resource utilization, final disposal, system construction, market system construction, technical system construction, regulatory system construction, stakeholder participation and sense of gain. This evaluation system will help cities develop their strengths and avoid weaknesses in C&D waste management, improve the level of waste management, and further promote the construction of “zero waste cities”.
