This paper presents guidelines for modeling the capacity of electronic household waste collection points. These points are used as infrastructure elements with a multi-stage logistic support scheme for the electronic waste disposal process. This paper includes theoretical and methodological information on the procedure for placing points of waste collection in cities using the processes of determining the parameters of waste accumulation, calculating the design capacity of warehouses at these points, and developing routes for the transportation of waste to the places of their disposal. We represent the dependence of the logistic support costs, including the costs of maintaining waste collection points, and waste disposal to utilization facilities, on the duration of the waste accumulation period. A mathematical model for optimizing the logistic support costs is developed, which takes into account the most important parameters of the waste disposal system, namely, the topology of the collection points, the intensity of waste accumulation, the configuration of the routes, and the vehicle carrying capacity. Using the example of the Vietnamese capital, the city of Hanoi, the required number of waste collection points is calculated, the volume of waste accumulation at each point is determined, the optimal period of waste accumulation, in which the total costs for logistic support for the disposal process will be minimal, is determined. Recommendations on the organization of waste transportation, depending on the actual level of filling the capacity of collection and accumulation points, are given.
