This research work presents an analysis of the possibilities to increase cactus biodegrability in a mixture with other types of biodegradable substances that can be degraded in a biodigestor. Based on the results obtained, the optimal amounts of biomass of the cactus Opuntia ficus, cow manure and water to generate biogas in the most efficient manner were determined. The prototype of the biodigestor designed based on the results obtained was approved by a Mexican company of the agricultural sector. The materials used for the fabrication of the biodigestor have a duration of 15 years. The viability studies performed showed high performance of the mixture used in the biodigestor. The technology used and the low maintenance cost makes the project economic for its sustainable use and demonstrates its competiveness to be expanded for use in small and medium businesses. A comparative analysis of the production of biogas between the different types of entries that the biodigestor can have is presented. The biodigestor designed is capable of producing methane (CH4) in a cheap and optimum way, taking advantage of the waste. Because it is isolated and completely closed off, it allows the decomposition process to be faster and more efficient.
