建筑废弃物资源化环境效益分析:以重庆为例

为了向政府提供可以提升建筑废弃物资源化环境效益的有利政策，以促进建筑废弃物资源化的可持续发展，本文从系统角度，应用系统动力学通过文献分析、实地调研、调查问卷等方法对建筑废弃物资源化的环境效益进行建模和模拟仿真.通过对环境效益模型进行情景分析，得出当非法排放单位罚款在50~60元/t，单位填埋收费取30元/t左右，建筑废弃物到资源化处置中心距离在15~25km左右，资源化的单位补贴额为25元/t左右时，可以使环境效益处于较优状态.同时政府应提高建筑废弃物相关法律的完善程度、培养相关人员的现场回收意识、促进相关科研研发，以期促进建筑废弃物资源化的环境效益.

Analysis on environmental benefits of construction and demolition waste recycling: A case study in Chongqing

Based on system dynamics through literature analysis, spot investigation and questionnaire results, the study of modeling and simulation of environmental benefit of Building Waste Resource recovery is carried to provide the favorable policy of lifting of environmental benefit to promote the sustainable development of building waste resource recovery. Through the scenario analysis of the environmental benefit modeling, it comes to the conclusion that the environmental benefit is in optimal state with 50yuan/t~60yuan/t of fine for illegal emission unit, about 30yuan/t of landfill charge, 15km~25km of distance of building waste to the center of resource recovery treatment and 25yuan/t of subsidy of resource recovery. At the same time, the government should improve the level of building waste related laws, cultivate the awareness of relevant personnel on-site recycling, and promote relevant research and development, in order to promote the environmental benefits of building waste resource recovery.
