उत्तर १
Biogas is a mixture of gases formed when a slurry of animal dung and water is allowed to ferment in the absence of oxygen (or air). Biogas is a mixture of methane, carbon dioxide, hydrogen and traces of hydrogen sulphide along with water vapours.
उत्तर २
- Biogas refers to a gas produced by the biological breakdown of organic matter in the absence of oxygen.
- Biogas is a type of biofuel.
- The biogas is produced by anaerobic digestion or fermentation of biodegradable materials such as biomass, manure or sewage, municipal waste, green waste, and energy crops.
- Biogas is also called swamp, marsh, landfill gas (LFG) or digester gas.
- A biogas plant is the name often given to an anaerobic digester that treats farm wastes or energy crops.
- Biogas can be produced utilising anaerobic digesters.
- These plants can be fed with energy crops such as maize silage or biodegradable wastes, including sewage sludge and food waste.

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. |
