Análise comparativa entre lixão e aterro sanitário: estudo de caso em Bom Jardim - MA.

Abstract

With population growth, cities expanded, causing an increase in the amount of waste generated. As a result, this waste is often discarded in landfills or dumps, as is the case in the city of Bom Jardim, causing various socio-environmental impacts. For these reasons, Law 12,305 of 2010 establishes a New Regulatory Legal Framework for Basic Sanitation, determining that by August 2024, landfills in cities with a population of less than 50 thousand inhabitants will be abolished. In this sense, the objective of this work is to make a comparison between the open dump and the use of landfills in Bom Jardim – MA. And, to collect data, site visits were carried out, taking photographic records and analyzing the physical circumstances. Furthermore, a survey of the observed environmental impacts was carried out, using the checklist model and the interaction matrix, to better demonstrate these impacts. Therefore, to solve the problems encountered and to ensure that there is an environmentally adequate final disposal of solid waste, it was suggested the implementation of a sanitary landfill, which must take into account the particularities of the region, making an Environmental Impact Study (EIA) essential.
