The anaerobic digestion process was applied in order to get biogas from goat’s manure. Two experiments were implemented. The first one was carried out by means of two lots, using matraces kitazatos of crystal with a capacity of 1 liter, as deposit of the mixture water - excrement. The kitazatos were put inside a tub with water warmed by an electrical resistance in order to supply the adapted temperature for the growth of the methanogenic bacteriums. The aim of this experimentation was to determine the daily production of biogas when goats’ manure is used. The second one was carried out by means of a biodigestor at laboratory scale. The small balls of goats’ manure were weighted and immediately were passed to a container where water was added. Then, these were dissolved in order to obtain a homogeneous mixture that could be loaded into the biodigestor. The aim of this experimentation was to determine the methane’s amount of biogas by means of chromatographic analyses.
