Análise da aptidão de áreas para implementação de aterro sanitário no município de Tauá (CE) com uso de SIG

Abstract

With the rate of exaggerated and increasingly disposable consumption, the amount of solid waste generated increases, leading to a series of problems related to the difficulty of implementing adequate solutions for the final disposal of solid waste. In this context, Federal Law N° 12.305, of August 2, 2010, emerged in Brazil, which established the National Solid Waste Policy (PNRS), which provides for the eradication of all landfills within the national territory, replacing them by landfills. Thus, the present work aims to identify areas suitable for installing a landfill in the municipality of Tauá-Ce, with the help of Qgis software, through multi-criteria analysis applied to Boolean Logic. The methodology of this study consisted of establishing restriction criteria, generating Boolean maps with classification of suitable/unsuitable areas. Therefore, as a result, it was possible to establish an area of 1.386,00 km2 , around 60% of the municipality's total territory, with classifications varying between reasonably favorable, favorable and very favorable. Thus, it can be concluded that the multicriteria analysis applied to Boolean logic, together with the use of Qgis software, proved to be adequate and efficient tools in locating areas suitable for the installation of a landfill.
