IDENTIFICATION OF AREAS FAVORABLE FOR THE IMPLEMENTATION OF SANITARY LANDFILLS BETWEEN SERTÃO MUNICIPALITIES IN THE STATE OF PARAÍBA, BRAZIL
This work aimed to identify potential areas for the installation of landfills among the nine municipalities of the Region Geoadministrative of Pombal (RGP), located in the interior of the State of Paraíba, based on current environmental legislation. The methodology proposed for the study consists of the use of geotechnologies, mainly the Qgis software, version 3.10.12, for the preparation of thematic maps based on the minimum criteria for landfill implantation, established by the current environmental legislation and competent public agencies , which are standardized for the same unit, assigning weights according to their aptitudes, based on the Analytic Hierarchy Process (AHP) methodology, classifying them in proper, good, regular and inappropriate areas for the implementation of a landfill. Among the results obtained, it was found that the most suitable sites according to the established criteria correspond to 1.5% (4.5 thousand ha) of the total area of the RGP. On the other hand, the unsuitable localities cover about 47% (136 thousand ha) of the studied region. Finally, it is expected that the information collected from this study will serve as a technical and scientific basis for the preparation of projects and/or programs for the municipal solid waste sector in the municipalities of RGP.
