This technical note uses an integer programming formulation and GIS tools to explore the feasibility of eliminating door-to-door solid waste collection in a community and replacing this municipal service with resident haulage of solid wastes to centralized depots. Obtained results show technical feasibility and considerable cost savings, which could be considered in the future by municipalities exploring options for their solid waste infrastructure systems.

Keywords: municipal solid waste, GIS, integer programming, waste collection, waste depot
