This paper presents an economic viability analysis of two investment alternatives for a pig farming located in the city of Jataí, Goias State, Brazil. The first investment alternative consists of the implementation of a biodigester, being the biogas burned in a flare. The second alternative also consists of a biodigester, nevertheless the produced biogas is used to generate electricity. The methodologies to estimate the methane production in anaerobic reactors are presented, as well as those for the quantification of the baseline and project emissions and of the electricity that can be generated. The results showed that the use of biogas for the electricity generation is the alternative more economically viable.
