What is bio gas?
Biogas is a renewable fuel and as such it is a part of the natural cycle. Biogas mainly contains methane (approx. 65 %). The rest consists mainly of carbon dioxide (approx 35 %) Small amounts of other gases can be found in the gas. The concentration of Methane depends on the raw material used in the biogas production. When burning the methane mainly carbon dioxide and water vapour is formed.
The difference between burning of natural gas and burning of Biogas is that the burning of biogas does not give any net contribution of carbon dioxide to the atmosphere. The carbon dioxide produced when burning the methane is consumed in the cycle of the nature by plants which produce biogas when fermenting which…… Methane is a greenhouse gas and the utilisation of the gas reduces the greenhouse effect of the atmosphere.
