“…This underscores the importance of modern decision-support tools for efficient fleet routing which is an important part of MSWM in smaller towns as it can influence the cost efficiency of the system. For decision-makers, solving the routing problem is all the more important as, due to the separate collection of recyclables and non-segregated solid waste, each site is visited several times during the planning period for the collection of a particular type of solid waste (Sundberg et al, 1994;Gellens et al, 1995;Korcyl et al, 2019).…”

Routing vehicles is a generic decision-making problem of strategic management in any business serving customers in distributed locations with a limited fleet including municipal solid waste collection. This paper introduces an approach tailored for optimizing waste collection routes in small towns and rural areas where dead-end streets are typical in the road network. Leveraging the Traveling Salesperson Problem (TSP), the approach employs optimal route determination taking advantage of the specific character of a road network with many dead-end streets. The service area for waste collection was aggregated, so the graph representing the map results in a relatively small data instance. This facilitated the application of the exact method, i.e. Mixed-Integer Programming using the OpenSolver tool in Excel. Conducted in collaboration with a municipal agency in southeastern Poland, this study outlines a comprehensive methodology, emphasizing the reduction of complex dead-end streets into singular nodes within the graph for effective route optimization. A comprehensive methodology is outlined alongside the solutions attained. Computational experiments focused on minimizing total travel distance during waste collection operations, demonstrating the methodology's success. Beyond efficiency gains, optimized routes hold potential for significant environmental impact reduction. The reduced travel distances result in decreased fuel consumption and emissions, aligning with sustainability goals. Developing an Excel-based decision support tool for municipal solid waste management is a significant contribution, particularly for decision-makers less familiar with Operations Research. The tool's compatibility within the spreadsheet environment streamlines waste management processes for municipal units, enhancing decision-making efficiency in optimizing waste collection routes.

The MWS model (MIMES/Waste for Sweden) is a systems engineering model for strategic planning of national solid waste management systems. It was developed for Sweden, but the general approach can be applied to other countries as well. The MWS model integrates cost minimization and emissions accounting and is intended for evaluating, from economic and environmental points of view, waste treatment technologies and waste management policies. The potential users of the model are, e.g. government agencies, companies, trade associations and funding authorities. In the MWS model, the Swedish waste management system is represented by 10 generalized municipal waste management systems. The integration of the generalized systems into a national model allows an analysis on a national level as well as on a generalized municipal level. A case study of the Swedish solid waste management system illustrates the application of the MWS model.
