Question

(b) Why is dung preferred for the production of biogas?

Hint:

Using dung for biogas not only produces clean energy but also minimizes methane emissions, contributing to sustainable waste management and climate change mitigation.

Answer 1

Dung is rich in organic matter and cellulose, ideal for methanogenic bacteria. It is affordable, abundant, and sustainable, producing renewable energy as biogas and nutrient-rich slurry, which serves as excellent manure for agricultural fields.
