摘要
科学健全的回收系统是建筑废物有效回收的重要前提,也是建筑废物资源化产业顺利发展的物质保障。在综述生产者责任延伸(extended producer responsibility,EPR)相关理论和实证研究的基础上,从产品生命周期入手,分析建材生产商在建材产品生命周期中应承担的延伸责任;阐释逆向物流理论及其对建筑废物回收的适用性,提出建筑废物逆向物流回收概念;基于EPR建立建筑废物逆向物流回收的4种模式并明确其利弊,构建数学模型综合比较不同模式相关参数最优值。结果表明:4种逆向物流回收模式中,生产商与第三方公司合作回收(CPT)模式下建材生产商利润、建筑废物回收量和回收意愿最大;建筑废物逆向物流产业链上参与主体越多,效益损失越多;建筑废物回收技术越成熟,其被回收的概率越高。
A scientific and sound recycling system is an important prerequisite for effective recycling of construction waste and a material guarantee for the smooth development of construction waste recycling industry.On the basis of the review of extended producer responsibility(EPR)related theories and empirical studies,the extended responsibilities of building materials manufacturers in the life cycle of building materials from the perspective of product life cycle were analyzed.Then,the theory of reverse logistics and its applicability to the recycling of construction waste were explained,and the concept of reverse logistics of construction waste was proposed.Finally,based on EPR,four modes of reverse logistics of construction waste were established and their advantages and disadvantages were clarified,and the mathematical models were constructed to comprehensively compare the optimal values of relevant parameters of different modes.The results showed that:among the four reverse logistics modes,the profit of building materials manufacturers,the amount of construction waste recycling and the recycling willingness were the greatest under the cooperative-partner take-back(CPT);the more participants in the reverse logistics industry chain of construction waste,the more benefit loss;the more mature the construction waste sorting technology is,the higher the recycling probability of construction waste will be.
