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 bio and agri-waste like sewage , etc this led Aditya and Amit to start Amrit Fertilisers, a biogas project, in 2014, without any government support.
