Abstract:Address to weak interregional coordination and mismatch of disposal capacity in various regions during the collection and disposal of waste circuit boards, the minimum distance maximum flow (MDMF) model was used to simulate the optimal flow path and flow of waste circuit boards across regions, and the environmental impact assessment of the optimization results was carried out. The results show that as the amount of waste printed circuit board generation increases year by year, according to the simulated optimized interregional recycling path, areas with typical waste printed circuit board treatment technology, such as Guangdong and Hubei, can reach their maximum production capacity, and the environmental impact under this condition is small. This study provides theoretical support for the regional coordinated planning of waste printed circuit board recycling system.
