Abstract:

To enhance the resource utilization rate of recyclable materials in municipal solid waste and optimize the recyclable material collection and transportation facility system, this study adopted two improved maximum coverage models to conduct layout optimization research for recyclable material transfer stations in Chaoyang District, Beijing. Based on the current layout status of recyclable material facilities, the accessibility of transfer stations was analyzed to determine their service coverage areas. Using population-weighted recyclable material collection points as demand points and actual road networks as transportation paths, seven layout optimization schemes for transfer stations were proposed. The results demonstrate that all schemes achieved optimization of transfer station layouts. Specifically, Scheme A exhibited the lowest transportation time cost (4,335.77 minutes), while Scheme C achieved the minimum construction cost (16.83 million CNY).
