Biogas is a renewable, high quality fuel, which can be utilized for various energy services such as heating, combined heat and power, or a vehicle fuel instead of the current practice of using fossil fuels (Machunga-Disu and Machunga-Disu, 2012). Biogas technology can serve as a means of reducing energy poverty, which has been a serious clog in the wheel of economic development in Africa (Adaramola and Oyewola, 2011). The methane and energy content of the gas generated usually varies and is dependent on the physical and chemical properties of the substrate used (Chenxi and Bruce, 2011).
