Dimensionamento de aterro sanitário de pequeno porte em Ribeirão do Largo, Bahia

Abstract

Proper management of urban solid waste is one of the concerns faced by cities, especially in developing regions, where population growth is not aligned with the evolution of infrastructure. In this context, Ribeirão do Largo is no exception. The increase in waste production, when combined with inadequate storage, can cause serious damage to the environment. The general objective of this work is to design a sanitary landfill using the trench method. The methodology analyzed the production of household solid waste, based on the proposed normative parameters established by ABNT and federal and state laws. The results obtained indicate that the per capita generation of waste in the municipality is 0.44 kg/inhabitant/day, with an average specific weight of 164 kg/m³. Given this information, it was feasible to design the sanitary landfill, designing a trench system with minimum measurements that would not compromise its technical and environmental effectiveness and functionality. In this way, the construction of this landfill met the prerequisites from an environmental and public health perspective required by law.
