Using Renewable Energy Source: An Introduction to Biogas

What is Biogas?

Biogas is a renewable source of energy produced from organic waste such as food waste, agricultural waste, sewage,etc through a process of anaerobic digestion. In the anaerobic digestion, microorganisms breakdown biodegradable material in the absence of oxygen to produce biogas. Biogas mainly contains methane (CH4) and carbon dioxide (CO2) along with small amounts of other gases.

The anaerobic digestion occurs in four stages to produce Biogas from organic waste. In the first stage, hydrolysis, enzymes excreted by bacteria breaks down insoluble organic polymers such as carbohydrates, fats and proteins into soluble components. In the acidogenesis stage, bacteria converts the products of hydrolysis into carbon dioxide, hydrogen, ammonia, and organic acids.
