SITE SELECTION FOR A SANITARY LANDFILL CONSTRUCTION IN PORTO VELHO/RO

Abstract

Many Brazilian cities dispose their waste in an inappropriate way, causing serious environmental impacts. Porto Velho, capital of Rondonia state (Brazil), is no different, and is under pressure for the selection of an appropriated place for the construction of a sanitary landfill. Thus, the goal of this work consisted on the identification of suitable areas for the installation of a landfill in Porto Velho/RO. The study was developed through analysis of spatial information and geoprocessing techniques. Results showed that Porto Velho has a large territory, but a small area that could be used as a sanitary landfill. It was selected 8 (eight) polygons with areas ranging from 318 ha to 3.199 ha, considering environmental and legal technical criteria. These areas still depend of an in loco environmental impact assessment, and economical and financial aspects evaluation.
