Alternativa locacional para implantação de aterro sanitário de pequeno porte no município de Boquira -Bahia.

Abstract

The inadequate disposal of Solid Urban Waste has become one of the major environmental concerns in Brazil even after the implementation of the Federal law 12,305 / 10 of the National Program of Solid Waste. This law indicated that all municipalities should present an environmentally appropriate destination for their waste. However, according to Abrelpe (2015), most Brazilian cities still launch it in open dumps or controlled landfills. This problem is not restricted to large cities, but also to small ones. In the state of Bahia, of the 417 municipalities, 359 still have an irregular disposition. Most of them have a small population and generate waste of up to 20 tons / day, thus meeting NBR 15.849, which establishes criteria for the implementation of small landfills. The town of Boquira, located in the semi-arid region of Bahia, fits this standard, as it has a population of less than 25,000 inhabitants and an estimated generation of waste of less than 20 tons / day. Since 1992, the waste generated in the municipality has been launched inappropriately in the lead tailings basin of Mineração Boquira, which contains high levels of heavy metals. Given the above, this study presents a proposal for a location alternative for the implementation of a small sanitary landfill in the town of Boquira-BA.
