Caracterização e avaliação do potencial de otimização da etapa de coleta de resíduos sólidos domiciliares: estudo de caso do município de Muriaé - MG

Abstract

Population growth, industrialization, and economic development intensify the challenges associated with urban solid waste management, particularly in large urban centers, raising concerns regarding sustainability, reverse logistics, and the circular economy. Inadequate solid waste management results in adverse environmental and public health impacts, including pollution and vector-borne diseases. Among the stages of urban solid waste (USW) management, waste collection represents one of the most significant, accounting for up to 70% of total management costs. Efficient waste collection is critical to the sustainable development of cities, and the selection of collection methods must integrate environmental, technological, social, and economic considerations. This study aims to characterize household solid waste collection in Muriaé, Minas Gerais, Brazil, where services are managed by the Urban Cleaning Department of DEMSUR, emphasizing optimization opportunities. The research methodology involved a web-based survey of relevant data, plans, legislation, and scientific studies on urban solid waste collection. Additionally, data were collected from the Municipal Department of Urban Sanitation in Muriaé, followed by processing and compilation of all information. The findings revealed an average efficiency of 75% in the household waste collection system within the municipality. Given the financial relevance of the collection stage, optimization efforts present a significant opportunity for cost savings in local public administration. The information and indicators provided in this study are expected to support the optimization and decision-making processes, enhancing the quality and efficiency of waste collection services. Furthermore, the study advocates for sustainable public service measures, contributing to financial savings while addressing diverse municipal demands.
