Answer:
Biogas from cow manure with 1 kg produced as much as 40 liters of biogas,while chicken dung with the same amount produced 70 liters. Biogas has a high energy content which is not less than the energy content of the fuel fossil [6]. The calorific value of 1 m3 biogas is equivalent to 0.6 - 0.8 liters of kerosene.
