Clean Energy: Biogas from Organic Livestock Waste

Is it possible to transform farm waste into clean and affordable energy? This book presents key research aligned with SDG No. 7 (Affordable and clean energy), whose purpose was to evaluate biogas production by anaerobic digestion of mesophilic bacteria in the district of Cuñumbuqui, San Martin. With a quantitative approach and a quasi-experimental factorial design, the study analyzed the energy potential of various local organic livestock wastes: excreta from chickens, guinea pigs, cows, sheep and goat whey.Through precise measurements with specialized technology over a five-day period, the findings revealed surprising data on the performance of each substrate. Bighorn sheep manure was crowned the most efficient treatment, achieving a remarkable 162.9% biogas production, followed closely by cow manure at 159.4% and whey at 128.8%. In contrast, poultry manure and corn manure recorded the lowest levels, at 112.1% and 102.7%, respectively. A fundamental reading to understand how applied science can democratize access to methane and change the lives of vulnerable communities.
