Question

List two ways in which animal dung can be utilised as a fuel. Out of these two which one do you think is better? Justify your answer.

Answer 1

The two methods of using animal dung as fuel are :-

(i) By dry the animal dung in sunlit and burning it to produce heat.

(ii) By putting them into the biogas plants where it converts into methane by the action of microorganisms on it and methane is a very good fuel.

I think the second method is more useful because in this method less pollution is created by burning and we an also dump other perishable wastes of our house in the biogas plants to make fuel.
