O uso de geoprocessamento para indicação de áreas favoráveis à construção de aterro sanitário no município de Jacundá – PA

Abstract

The accommodation of Urban Solid Waste (MSW) in unsuitable places, such as garbage dumps, in addition to polluting the environment favors the propagation of vectors that transmit disease. In order to eliminate the social, economic and environmental damages caused by the incorrect disposal of solid wastes, law 12,305 / 2010 instituted the National Solid Waste Policy (PNRS). This law establishes, among some sanctions, that all municipalities in Brazil must transform their inadequate waste deposits into environmentally sustainable landfills by 2014. Based on the National Solid Waste Policy and the current situation of the MSW disposal system of the municipality, this work has as main objective to generate a map identifying the areas favorable to the implantation of a new landfill. Using the multicriteria analysis and the Boolean method, it was possible to carry out the selection and classification of lands using geoprocessing techniques based on geoenvironmental criteria. The result obtained generated a map classifying areas as inapt, restricted, moderate and favorable to the implantation of a landfill in the municipality of Jacundá-PA.
