| Summary: | Cattle manure has an energy potential that is unknown to farmers. In the rural areas of the city of Latacunga - Ecuador there are inconveniences for the transport of the G.L. (Liquefied Petroleum Gas). For this reason, this document shows the implementation of a biodigester to obtain biogas for domestic use at Hacienda Terán located in La Dolorosa Belisario Quevedo, the cattle manure is analyzed, obtaining 13.7% of total solids. In addition, it was established that 100 kg of mixture with the quantification of manure in a period of 12 days. In order to maintain the elevated temperature a greenhouse was built obtaining an average of 28.48°C in a time for the generation of biogas in 30 days and a minimum temperature of 22.7°C. Temperatures that are within the limits established for the generation of biogas. With these parameters. a 4.25 m3 bio-bag was dimensioned generating a production of 1.1 m3 of gas that satisfies the family use of 0.7 m3 Biogas and G.L.P. firing tests were carried out up to 80° C obtaining a calorific value of 4800 kcal. per m3.
