The purpose of the research is directed to the design of a Biodigester where bovine manure and wastewater are used for the creation of low-cost fuels. A Biodigester is a system that takes advantage of anaerobic digestion (in the absence of oxygen) making use of the bacteria that live in the manure, which help to transform it into biogas that will be used in kitchens and as an alternative source of electricity once it has passed through the electric generator of transformation that operates based on gas and in turn obtain the fertilizer called Biól, which after having served its time in the Biodigester is considered with the same importance as the Biogas since it provides an excellent natural fertilizer that improves the yield of crops, allowing to obtain a better product. Low-cost biodigesters have been developed and are widely implemented in Southeast Asian countries, but in South America, only countries such as Cuba, Colombia and Brazil have developed this technology. They are characterized by their low cost, easy installation and maintenance, using simple materials for their construction.
