RESUMO

Disposal of waste into landfills represents one of the most important problems in urban sites, particularly in Brazil where the use of "open dumps" is still very common. Uncontrolled emission of biogas produced by anaerobic decomposition of the organic matter can be a local environmental hazard causing vegetation damage, unpleasant odors and may form explosive mistures at concentrations from 5 to 15 per cent in air. Biogas can also be global problem, once it is constituted by at least 50% of methane, which is an aggressive greenhouse gas. The use of produced biogas can promote many benefits for the local govemments, extimulating the adoption of engineering practices that maximize the biogas generation and collection efficiency, also reducing the risks of environment contamination. This study comprises field testing in Delta landfill located in Campinas city where were there performed composition analysis and flow measurements of the biogas emitted from the site to evaluate the electric power generation potential using biogas as combustible. The future biogas production was also calculated for the landfill adopting a methodology presented in the literature, using measured data as initial input. It was concluded that the landfill will achieve it s maximum potential (4MW) one year after the closure of the site that is planed to happen in 2006. The production of biogas tends to decrease exponentially until the end of the organic matter consumption
