A mathematical model was applied to analyze cooperation among producers in waste management.• The Shapely value was used to show the potential cost to the waste producers in the case of cooperation. • A case study for the process of waste management was investigated.In this paper, we apply a mathematical model based on cooperative game theory to model cooperation among producers in waste management. Then, we use the Shapely value as a solution concept in a cooperative game to evaluate the cooperation existing among producers, in order to show the potential cost to the waste producers in the case of cooperation and reduce the overall costs of processing non-recyclable waste during the cooperation. Thus, this study concludes that all producers divide sanitary landfills or incineration of nonrecyclable waste, meaning that for each producer who earns more, there will be a greater contribution to the disposal or treatment of non-recyclable waste.
