Nigeria biogas potential from livestock manure and its estimated climate value

This paper estimates Nigeria biogas potential from livestock manure and its contribution to climate change mitigation. Findings reveal that Nigeria biogas potential from livestock manure represents a minimum of 1.62 x 10(9) m(3) of biogas per annum. Replacing diesel fuel with methane derived from biogas to produce electricity as well as inorganic nitrogen fertilizer with organic nitrogen from the anaerobic digester for agricultural use will lead to carbon dioxide (CO2) emission savings of 683,600 t per annum. This amount represents the minimum contribution of biogas derived from livestock manure to climate change mitigation if harnessed for electricity and agricultural use in Nigeria.
