Efficiency and Cost Management in Solid Waste: the Impact of Public Consortia in Northern Minas Gerais

Objective: This study aims to investigate the relationship between solid waste management indicators and the participation in public consortia in the northern region of Minas Gerais, seeking to identify characteristics of both consortium and non-consortium municipalities in terms of efficiency and cost management. Theoretical Framework: Key concepts and theories on municipal solid waste management, public consortia, and economies of scale are presented, providing a solid foundation for understanding the research context. Method: The study employs a documentary and statistical approach, analyzing data from municipalities in northern Minas Gerais. Data collection was conducted through platforms like the National Solid Waste Management Information System (SINIR) and the Spatial Data Infrastructure IDE-SISEMA, covering indicators such as collected mass, management and collection costs, and socioeconomic data. Results and Discussion: The results showed that consortium municipalities had lower per capita management costs and less cost variability, while Montes Claros, a non-consortium municipality, stood out with better indicators than the regional average. The discussion contextualizes these results with the theoretical framework, highlighting the efficiency of consortia in reducing costs and improving management. Discrepancies and study limitations are also considered. Research Implications: The study provides insights into how the results can influence practices in solid waste management, impacting public policies and municipal consortium strategies. Originality/Value: This study is pioneering in analyzing this specific relationship in the region, demonstrating the effectiveness of public consortia and guiding municipal managers in decision-making regarding consortia and waste management.
