Evaluating Comprehensive Benefits of Construction and Demolition Waste Recycling in Pressure-State-Response Framework
摘要
Abstract
Reasonable evaluating the economic benefits and social welfare of construction and demolition waste (CDW) recycling contributes to CDW investments and decision-making. The formation mechanism of comprehensive benefits on CDW recycling is analyzed by applying the pressure-state-response framework from the resource economics, and the article constructed the evaluation model of comprehensive benefits on CDW re-cycling. The context of CDW management, supply and demand of recycled products, and the input-output effec-tiveness of CDW management are determined and discussed in the case of Chongqing. These findings suggest that 1) the CDW recycling rate changed between 0.06 and 0.14, which indicated that construction and demolition waste are mostly in landfill; 2) the supply-demand ratio of CDW recycled products fluctuates between 0.1 and 0.25, which suggests that the supply-demand of recycled products is a serious mismatch, and then this mismatch is the pressure and driving force of CDW recycling development; 3) the benefit-cost ratio of CDW management varies between 0.16 and 0.35, which suggests that the input-output of CDW management is a significant disproportion, and the disproportion not only conforms to the economic man of the investor who do not participate in CDW recycling, but also reflects the stakeholders' response to CDW management. Based on the previous study, the suggestion is dis-cussed and studied on the CDW supply-demand side applying supply-demand ratio and benefit-cost ratio.关键词
