Abstract: To enhance the resource utilization rate of recyclable materials in municipal solid waste and optimize the recyclable materials collection and transportation facility system, two improved maximum coverage models were adopted to conduct layout optimization research for recyclable materials transfer stations in Chaoyang district, Beijing. Based on the current layout status of recyclable materials facilities, the accessibility of transfer stations was analyzed to determine their service coverage areas. Taking population-weighted recyclable materials collection points as demand points and actual road networks as transportation paths, seven layout optimization schemes for transfer stations were proposed. The results demonstrated that all schemes achieved optimization of transfer station layouts. Specifically, scheme A exhibited the shortest transportation time (3 747.34 minutes), while scheme C achieved the minimum construction cost (16.84 million CNY).
