Question

What is biomass? Explain the principle and working of a biogas plant using a labelled schematic diagram.

Answer in Brief

Solution

The source of fuel which is produced from the plant and animal remain are called biomass.

In biogas plant, the remains of plant and animal are used to make the slurry. This slurry is poured into a dome like structure. The slurry undergoes the endothermic reaction. Because of this reaction, biogas is released which is collected at the top of the dome. Finally from the exit portal the gas is taken out.

In Kunjpura village, located in Karnal district, Haryana, Aditya Aggarwal and his older brother Amit Aggarwal run Tee Cee Industries, a steel plant set up by their ancestors in 1984. Along with this, they also run a gaushala that houses 1,200 cows that can no longer produce milk.

The cow shelter was manageable but running the steel plant was turning out to be expensive because they spent a whopping Rs 5 lakh every month on electricity.

The brothers struck upon an idea. Why not run the factory with the biogas produced from cow dung from the shelter and other gaushalas, along with a bio and agri-waste like sewage, farm waste, etc. This led Aditya and Amit to start Amrit Fertilisers, a biogas project, in 2014, without any government support.
