Biogas plant of 2m3 was developed for the codigestion of 25% SpBMS +75% cow dung substrate. The dome has provided with additional stirring mechanism to break the scum formation inside digester. The developed plant was further evaluated continuously for 80 days by daily feeding a mixture of 12.5 kg of spent button mushroom substrate and 37.5 kg of fresh cow dung with 100 kg of water. 100 kg of water with 50 kg of selected substrate (12.5 kg SpBMS +37.5 kg cow dung) was mixed daily to maintain 10% solid content of material. The hydraulic retention time (HRT) of the modified biogas plant was 40 days, so the observations of produced biogas were recorded daily throughout two cycles of HRT (80 days). The observations were recorded from 4th February, 2016 to 23rd April, 2016. The average daily biogas production during 80 days of biomethanation period was observed as 1.852 m3/day.
