This work presents a case analysis of energetic harnessing in a piggery, based on the use of biogas generated from pig sewage. The analysis shows that the energy from the biogas produced in the farm processes can be partially used through Clean Development Mechanisms (CDM) in order to improve the system efficiency. The utilized process presents environmental and economical benefits as carbon emissions are reduced and their credits can be traded. Moreover, an economic analysis of alternatives for biogas use was carried out taking into account technical, environmental and financial aspects. The case study was realized on a piggery farm in the south-west of the Goiás State where the economical viability of each of the presented alternatives was analyzed considering the following: total burning of biogas; generation of electrical energy; heating; or the combined heat and power generation (CHP).
