Academic Assessment of Global Biogas Potential from Cattle and Buffalo Dung Using a 50% Methane Recovery Baseline
Abstract: This academic study estimates the global and regional biogas potential from cattle and buffalo dung using a 50% methane-content baseline. Global livestock data (1.57 billion cattle and 205 million buffaloes) and published manure yield factors were applied to quantify dung production and theoretical biogas yield. Results indicate approximately 6.63 billion tonnes of dung annually, capable of generating about 198.9 billion m? of biogas, equivalent to 77 million tonnes of liquefied petroleum gas (LPG). This potential could theoretically replace around 50% of global domestic LPG consumption. Present biogas output (approximately 40 billion m? natural gas equivalent per year) remains far below this potential, revealing substantial untapped renewable energy within livestock systems. The findings emphasize the role of manure-based biogas in reducing fossil LPG dependence, strengthening rural energy security, and supporting climate-smart agriculture and circular economy strategies.
