Various parameters such as concentration of slurry, pH, moisture, total solids, temperature, and C/N ratio are among the main parameters affecting biogas production. The carbon and nitrogen contents of various biogas feedstocks were determined using standard methods and the volume of biogas produced by the substrates were measured using the graduated gas cylinder. The results show that carbon to nitrogen ratio affects the volume of the generated biogas. The production of biogas depends to a large extent, on the choice of feedstock and its carbon to nitrogen ratio.
