Question

how to utilise biogas ?​

Answer 1

Answer:

Biogas is also known as gobar gas. The gases produced by anaerobic decomposition of organic matter such as manure, municipal waste, plant material, agricultural waste, cow dung, sewage, food waste, green waste etc. are called biogas. Thus, biogas is not a one gas but instead it is a mixture of gases. Carbon dioxide and methane make up the majority of biogas. It is a source of renewable energy. Biogas is created when organic matter decomposes through a process known as anaerobic digestion. In the absence of oxygen, microbes break down the plant or animal waste, releasing gases such as carbon dioxide and methane. Renewable energy sources are gaining popularity around the world. Biogas output is gradually increasing as more people set up biogas plants to generate fuel.Cow dung is the main source for production of biogas as it contains many bacteria naturally which help in anaerobic decomposition of organic matter. This is the reason biogas is called gobar gas. Cow dung contains methanobacterium which is found in the rumen of the cow's digestive system. Methanobacterium not only produces methane gas but manure as well by decomposition of bio waste. 

Answer 2

The answer to the given question is as follow:

Biogas is a gas mixture primarily composed of methane and carbon dioxide that is created from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste, and food waste. It is a renewable source of energy.

Ways to utilise biogas:

• Biogas can be used in direct combustion systems (boilers, turbines, or fuel cells) to generate space heating, water heating, drying, absorption cooling, and steam generation.
• The gas used directly in gas turbines and fuel cells has the potential to generate electricity.
