Research on reverse logistics recovery model of construction waste based on EPR

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.
