A municipal solid waste landfills are complex systems, because your waste in a landfill body has a large heterogeneous mixture, high levels of different organic and inorganic matter. Environmental problems are results about intense urbanization, but different solutions offered for alternatives mitigating the environmental impacts. These solutions are the best practices in the recovery of such wastes when disposed of in landfills. But recent concepts in modern landfill management, in the São Paulo City, incorporate strategies in their life cycle, so since the beginning of the landfill, different techniques have been tested to stabilize the amount of methane gas emissions and energy recovery. This work finds the perspective, sustainability electricity generation, these uses of landfill gas are divided into electricity generation and direct use. The scenery, study sustainability indicators are Bandeirantes Landfill, with application of fuzzy logic to estimate production methane for energy generation.
