SUMMARY:

In 2018 the Brasília Landfill (ASB) was inaugurated in the Federal District as a result of the PNRS (2010) publication, which began to receive the solid waste generated in the capital. In addition, several initiatives were developed to reduce the volume of landfilled waste. However, the landfill that had been planned for thirteen years was now expected to operate for a little more than ten years, since the actions were not very effective. With the observed increase in landfilled waste, it will soon be necessary to find another place to landfill the waste. There is also the possibility of expanding the ASB. The present work evaluated the possibilities of location for a new landfill to serve the population of the DF, considering the Integrated Development Region (RIDE/DF). To this end, Hierarchical Process Analysis (AHP) and Boolean Logic were employed. Both methodologies were validated through bibliographic research of works with the same theme. The AHP was developed and the criteria were defined and weighed based on the conclusions coming from the research of similar works. Eleven criteria were chosen: Water Resources; Slope; Soil; Groundwater; Conservation Areas; Geology; Highways; Distance to Airports; Distance to Urban Centers; Land Use and Land Cover; Towns and Villages. The use of Boolean logic was carried out through the interpretation of the legislation applicable to the case, defining restrictive criteria that were incorporated into the AHP with a zero score. A calculation was also made of the land area needed for the landfill, to serve the entire population of the Federal District over 20 years. The development of the work was done with the help of GIS tools and the data used was downloaded from public portals and independent projects. Maps were generated for each criterion that was crossed, arriving at a map with areas defined as "inadequate", "too little adequate", "little adequate", "adequate" or "very adequate". With this result, a filter was made among the "very suitable" areas to arrive at a location that could meet the expected population, that was defined as a preferred region.
