Transformación Sostenible: Generación de Biogás a partir de Estiércol Animal mediante Biodigestores en la Comunidad María Eugenia, Yaguachi

This article addresses the generation of biogas from cattle manure using biodigesters in the María Eugenia community, Yaguachi, Ecuador. The objective of the study was to implement a clean and sustainable energy alternative for the community, aligned with the United Nations Sustainable De-velopment Goals 3 and 7. The methodology involved the construction and operation of a 20-liter scale anaerobic biodigester, using bovine manure as the raw material. Analyses of pH, temperature, and organic matter content were carried out to evaluate the efficiency of the anaerobic digestion process. The results showed that the biodigester was effective in producing biogas, with an optimal pH range between 7.22 and 7.72 and an average temperature of 25.5°C—conditions suitable for the activity of methanogenic microorganisms. The organic matter present in the cattle manure was sufficient to generate high-quality biogas, and moisture levels were maintained within appropriate ranges for the process. In conclusion, the use of biodigesters in the María Eugenia community not only provides a renewable and sustainable energy source, but also contributes to efficient organic waste management, reduces dependence on fossil fuels, and supports the fight against climate change.
