Identification and characterization of Municipal Solid Waste - MSW through geoprocessing and visual analysis of waste in Brazil

This work sought to identify places with irregular dumping of solid urban waste and characterize them, assisting in the public management of these materials through a quick survey method. Belém, Capital of the State of Pará, Brazil, it was defined as a research area because it is observed that there are several places of irregular MSW dumping, impacting the quality of life of the population. Mapping and photographic survey and visual classification of the materials in the composition of the waste were carried out. The data were processed using the Quantum GIS software and Microsoft Excel. The analysis considered the relative frequency of identified materials, the most present: wood, construction waste, pruning and clearing materials, plastic materials and the presence of residential waste. 95.6% of the materials are from residential origin. Those materials have a great economic potential 61.6%. The presented methodology is a quick and practical solution for places with few technical and human resources in a way that assists in environmental management meeting a demand for a quick classification of the types of materials that will be sent to the final destination of solid waste or an adequate system screening.
