Abstract

Open pit dumps, previously used as the quickest solution by municipal managers for the final destination of solid waste, have become a major environmental and social problem, contaminating the air, soil, surface and groundwater. Thus, it was necessary to select safer alternatives for the disposal of this waste, including the construction of landfills. Law 12.305 / 2010 instituted the National Solid Waste Policy, in order to promote the implantation of sanitary landfills in the municipalities together with the closure of the open landfills. To achieve this objective, environmental diagnoses have been carried out in the municipalities of Bahia, including Paulo Afonso, which will be contemplated with the implantation of a Sanitary Landfill. This article discusses the criteria used to select areas in order to implement the aforementioned Landfill, taking it as a case study. To this end, local characteristics regarding the infrastructure, physiographic and socioeconomic aspects of the municipality. In addition, population growth was projected for a time horizon of 30 (thirty) years, this being the forecast for the duration of the future landfill operation. Research was also carried out regarding possible legal restrictions on the implementation and operation of the enterprise. The final choice of area / land for the implementation of the project represents the most adequate to the pre-established criteria.
