Seleção preliminar de áreas para instalação de unidade de gerenciamento de resíduos sólidos para o Município de Cataguases – Minas Gerais

Abstract

This study aimed to conduct a preliminary analysis of potential suitable areas for the implementation of a new landfill in the municipality of Cataguases. Additionally, it sought to perform a critical analysis of the municipal solid waste management and outline its future perspectives. The methodology adopted involved the creation of maps to identify suitable and unsuitable areas for the landfill, taking into account criteria established by NBR 15849, CONAMA Resolution No. 404/2008, and COPAM No. 118/2008. Factors such as slope, presence of watercourses, environmental restrictions, railways, and highways were considered. The results revealed the identification of a large unsuitable area for the landfill implementation in Cataguases, according to the established technical criteria. This identification is crucial to ensure the efficiency and sustainability of the solid waste management system, as well as the preservation of the environment and protection of water resources. However, several unrestricted areas were also found, offering viable options for the landfill installation in accordance with current legislation. These areas exhibit favorable characteristics, such as suitable slope, absence of watercourse and spring protection, and freedom from environmental restrictions, railways, and highways. The conclusion of the study emphasizes the importance of making an appropriate choice for the landfill location, considering only the technical criteria. This information is fundamental to contribute to ensuring the efficiency of the solid waste management system, as well as minimizing negative impacts.
