Multicriteria Analysis for the Solid Waste Management Model in Bolívar Canton

The purpose of this research was to develop a solid waste management model for the Bolívar canton, considering environmental, economic, social, and technical criteria through a multicriteria analysis approach. The supply chain was characterized through a detailed analysis of the urban solid waste management process in the Bolívar canton, including its different stages and stakeholders. Supply chain flows were defined by identifying and quantifying the waste streams currently circulating within the chain. Finally, the solid waste management model was determined based on the requirements proposed by the AME (Mexico City Association of Solid Waste) in its comprehensive management project for non-hazardous solid waste generated in Ecuador. This research is proposed as a strategic tool for moving toward more sustainable and resilient cities. Consequently, investing in this type of model entails short-, medium-, and long-term benefits, ensuring balanced development across the environmental, social, and economic spheres. The results show that solid waste generation in the Bolívar canton is 0,72 kg/inhabitant/day, with minimal variations across parishes. In the residential sector, generation reaches 0.36 kg/inhabitant/day, equivalent to 50 % of the total. Furthermore, the monthly cost per household for the GIRS (Mexico City Association of Solid Waste) is estimated at USD 6.60. This information is key for planning and optimizing the collection system, contributing to more efficient and sustainable management.
