Abstract:

Most developing nations are faced with energy crisis and waste management problems. To solve these problems, a transition from sole dependence on fossil fuels due to their high cost, scarcity, and environmental pollution to a more circular, economy-based, and environmentally friendly source of energy that can promote sustainable waste management becomes promising. Therefore, the massive quantity of animal dung from animal husbandry provides a considerable amount of feedstock that can be accessed for biogas generation as a reimagined process for recovering energy from waste. The paper aimed at using dung from 368,557,554 livestock in Nigeria as a significant resource for energy generation. The emphasis is on dung, considering the amount of biogas produced from 1kg of dung and the energy volume that can be generated from biomass using excreta. This work primarily adopted secondary data to present Biogas as a significant fuel source in Nigeria. Based on statistical data, the methodology applied mathematical computation to ascertain the daily waste generation. The results revealed that the daily quantity of manure generated is 457,025.6 tons. The estimated total human waste per day is 250,463.4 tons, and the total amount of manure produced daily by livestock is 206,562.2 tons; human excreta amount 12,523,170m3 of biogas daily and 4,570,957,050m3 annually, and livestock produces 7,939,294.6m3 of biogas daily and 2,897,842,529m3 annually indicating that Nigeria can generate 14,937,599,158m3 of biogas from waste. The estimated thermal energy generated from manure as a resource for energy conversion in Nigeria equals 122,774,787.6kWh and 44,812,797,474kWh (44.813 billion kWh).
