Biogas production from selected crop residues in Nigeria and estimation of its electricity value

The production of biogas from peels of watermelon (WP), banana (BP) and potato (PP) was investigated in the laboratory scale using the simple single–state digesters of 1.5 L working volume. The digester was fed on a batch–basis with the slurry of WP, BP and PP containing average moisture content of 18% and operated at temperature of 35°C for 30 days. Measured biogas yields for WP, BP and PP were 0.46, 0.42 and 0.56 m3 (kg ODM)−1 respectively after 30 days digestion time. Methane production from WP, BP and PP was 0.23 (49.8%), 0.24 (56.55) and 0.30 (53.2%) m3 (kg ODM)−1 respectively. Results of this study suggest that 24,080 million and 38,520 million kWh of electricity can be generated from biogas at a low–end efficiency of 25% and at the high–end conversion efficiency of 40% respectively using only seven prominent energetically available crop residues in Nigeria.
