Abstract Existing waste management systems frequently fail to achieve anticipated results owing to competing aims and limited resources. Collecting and delivering solid waste to locations where their respective management practices could be improved is fundamental to managing the above practices. Solid waste management has become a significant issue in Nigeria, aggravated by growing urbanization, population increase, and industrialization. Inadequate waste management infrastructure and methods have resulted in widespread pollution, health risks, and economic losses. Goal programming, a modification of linear programming aimed at a specified goal, is proposed for this study. Goal programming is also an expansion of linear programming problems. Hence, the basis for the model is developed mathematically with mixed integers. The model aims to optimise waste management by minimizing the cost of waste disposal (SWM). It consists of transporting various waste products from different locations and the fixed cost of establishing and operating or maintaining the waste management facilities. The nodes used in the transportation network include collection, composting, recycling, hazardous, combusting, final disposal nodes, and a combination of any of the above. Therefore, this research is expected to minimize the cost of transporting waste products and maximize the profit from properly disposing of the waste.
