Abstract
An assessment of biogas production from chicken droppings by anaerobic co-digestion with Cymbopogon citratus (lemon grass) was carried out. The composite pre-fermented substrates were mixed with water and the formed slurry was digested separately in five batch anaerobic plastic digesters for a period of 30 days. The pressure on the digester by the produced biogas was determined using a tri-axial quarter-bridge strain gauge rectangular rosette, carefully fixed to the external surface of the plastic digester. Hourly readings of corresponding gas pressures and digestion temperatures were recorded electronically. It was observed that the highest biogas yield was from lemon grass digested alone while the single digestion of chicken waste gave the lowest yield. Results showed that 100% chicken droppings produced 12.89 kP of biogas whereas C. citratus alone produced 42.00 kP. Codigestion of 70% chicken droppings with 30% C. citratus was the optimum mixture as it enhanced and almost doubled the gas production of chicken droppings from 12.89 kP to 21.00 kP. The study has shown that the biogas production from chicken droppings could be enhanced by co-digestion with lemon grass.
