ALTERNATIVAS LOCACIONAIS PARA A IMPLANTAÇÃO DE ATERRO SANITÁRIO NO MUNICÍPIO DE RIO VERDE - GOIÁS

Abstract

Accelerated population growth, the high exploitation of raw materials to meet the needs of the population, is causing the large generation of urban solid waste, thus making it difficult for municipal managers to manage this entire volume of waste, and in several cases, generating significant impacts on the environment. The lack of adequate final disposal is highlighted in most Brazilian municipalities, due to financial issues, poor management or lack of areas suitable for landfills. In this way, this study aimed to find suitable areas for the implementation of landfill in the municipality of Rio Verde in the state of Goiás, since the municipality does not carry out the proper disposal of urban solid waste, thus failing to comply with Federal Law No. 12305/2010. The methodology consisted of spatial analyzes applying the criteria provided for in the Brazilian legal framework, using the free software QGIS for processing data obtained through the Brazilian Institute of Geography and Statistics, National Institute of Space Research, State System of Geoinformation, Environmental Systems Research Institute and City Hall of Rio Verde. The result found through the preparation of suitability maps identified 1,288.25 Km² of areas suitable for the implementation of the sanitary landfill in the municipality of Rio Verde according to the criteria of distance from the airfield, topography, distance from water courses, accesses, size minimum, minimum distance from population centers and areas already anthropized.
