RESUMO:

The environmentally appropriate destination for solid urban waste is recycling and / or composting and, when all possibilities of using this waste are exhausted, the incineration and / or disposal of waste in landfills. However, about 40% of the world's waste is disposed of inappropriately in controlled dumps and /or landfills. The environmentally appropriate way of disposing of this waste is landfills. This study aimed to identify areas for landfill implementation in the Metropolitan Region of Salvador, with the help of the geographic information system, and the analysis of multicriteria decision. Two preliminary models were generated: the first used restrictive criteria established by Brazilian legislation applied to fifteen factors / themes; in the second, non-restrictive criteria applied to eleven factors / themes were used, based on technical knowledge and literature, defining weights using the AHP method. The first model showed 30% of suitable areas and 70% of unsuitable areas. The second model presented 8.4% of very favorable areas; 32.4% favorable; and 59.2% were not favorable. Finally, the final model, resulting from the crossing of the two models, where 6.05% of the total areas were classified as very favorable; 15.95% favorable; 8.56% not favorable; and 69.44% inapt areas. Although the proposed method is applicable in any geographic region, it is necessary to understand its limitations and / or modifications, since the factors and criteria used are inherent to the areas studied and it is only possible to establish strict rules for restrictive criteria when there are specific laws. In the case of non-restrictive criteria, the analysis is subjective, with the specialists being responsible for determining the decisions.
