Biogas is an excellent fuel. Justify the statement by giving two reasons.Mention the constituents of biogas.
Because of the following features biogas is an excellent fuel:
1. Biogas is a clean fuel. Compared to the use of diesel for vehicles, biogas emits 80% less hydrocarbons and 60% less nitrogen oxides. The concentration of particles and dust is also negligible when biogas is burned.
2. Biogas will never run out. All animal and food wastes can be used to produce biogas. So, as long as humans and animals exist on the planet, biogas will go on being produced.
Biogas is obtained from the excretion of animals like cow dung and plant wastes.
Following is the composition of biogas:
Methane: 50% to 75%
Carbon dioxide: 25% to50%
Nitrogen: less than 10%
Hydrogen: less than 1%
Hydrogen disulphide: less than 3%
