This study evaluates the technical and financial aspects of feasibility for biogas production from opuntia and its use in power generation, such as equipment performance, transportation, workers, machinery, etc. The results indicate that opuntia is a highly methanogenic source due to its chemical structure, as well as, short holding times inside the reactor, with a high conversion rate. As design parameter, for this study, is estimated a 1600 m3 biogas / day production, with an overall plant performance 95%, and a composition of 75% CH4 and 25% CO2.
