Abstract
The study was carried out to find out if it is feasible to use guinea pig excretions for the generation of biogas as an alternative energy source at altitudes above 2,500 meters above sea level. Two types of biodigesters were investigated, one discontinuous and the other Taiwanese. The biogas was subjected to a gas chromatography analysis, which showed the concentration in weight and moles of CO2, methane, nitrogen and water, relative density, molecular weight and caloric value. The gas from the discontinuous biodigester was the one with the best results, since its composition had 50.10 % mol of methane.
Keywords: biodigesters, biogas, taiwanese biodigester, discontinuous biodigester.

Resumen
El estudio se realizó para averiguar si es factible utilizar excreciones de cuy para la generación de biogás como fuente de energía alternativa en altitudes superiores a los 2.500 metros sobre el nivel del mar. Se investigaron dos tipos de biodigestores, uno discontinuo y otro taiwanés. El biogás se sometió a un análisis de cromatografía de gases, que mostró la concentración en peso y moles de CO2, metano, nitrógeno y agua, densidad relativa, peso molecular y valor calórico. El gas del biodigestor discontinuo fue el de mejores resultados, ya que su composición tenía 50,10 % mol de metano.
Palabras Clave: biodigestores, biogás, biodigestor taiwanés, biodigestor discontinuo.
