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 kg of spent button mushroom substrate and kg of fresh cow dung with 100 kg of water. 100 kg of water with 50 kg of selected substrate ( kg SpBMS + kg cow dung) was mixed daily to maintain 10% solid content of material. | Development of improved biogas plant for biomethanation of spent mushroom substrate and cow dung
