Obtenção de energia limpa a partir da captação do biogás no aterro sanitário de Salvador

Abstract

This paper presents a review of literature on the municipal solid waste transformation processes in the landfill for obtaining clean energy. We aimed to show the processes involved in the treatment of the waste at the landfill until to capture and biogas use. Taking into account that the correct treatment of the waste at the landfill entails an onerous investment to public coffers, this study becomes of great importance to contribute to the academic environment as a source of enlightenment and understanding about the final disposal of waste as well as the processes involved in environmental management Landfill in Salvador, soon, with informative and educational purpose. The disposition of municipal solid waste in the ground is a technique that aims to protect the harms or risk to public health as well as minimizing environmental impacts. In the present study showed that the influence of the operational characteristics of a landfill are extremely critical to that are expected results close to those estimated at project, indicating that the absence of adequate criteria for sizing enables even greater errors. Regarding the use of biogas, although some of the alternatives currently used are not technically suitable for large-scale deployment, this denotes the need of a national effort to develop new technologies at affordable costs, increasing the use of biogas and avoiding the current energy waste. The use of biogas in landfills and is a source of energy, has a contribution to reducing emissions of greenhouse gases. The implementation of the Termoverde power plant with the Metropolitan Landfill Center is an initiative that is working fine. In addition to selling electricity in the Free Energy Market, the company also sells carbon credits, according to the Kyoto Protocol.
