Abstract: In the present study, we have developed a batch reactor setup to monitor the formation of biogas using sago (cassava) wastewater for the first time. The experimental parameters like pH, COD, BOD, volatile solids, have been tested to optimize the production of biogas. The liberated biogas was analyzed and found that, about 65 – 70 % of methane and remaining 20–25 % of CO 2 . Sago effluent contains large amount of organic material which has a potential to cause water pollution. In order to reduce this problem, an experiment was conducted to remove organic material and biogas recovery from sago effluent using lab scale batch reactor. The biogas produced in the first reactor of 750 ml feed was 3393 ml per liter of liquid waste and similarly the biogas produced in the second reactor of 1250 ml feed was 3068 ml per liter of liquid waste.
