用户：Gas gets collected when livestock animals exhale. During leisure or resting period, they release around 300 to 500 liters of methane per animal. A large amount of biogas power is obtained from such anaerobic fermentation of animal dung. We have successfully developed biogas digesters to turn agricultural waste into efficient energy. The diversified biogas applications cover heating, powering farming tools, and illuminating rural areas".
