Detailed explanation-1: -Biogas is a mixture of methane, CO2 and small quantities of other gases produced by anaerobic digestion of organic matter in an oxygen-free environment.
Detailed explanation-2: -Biogas is generated during anaerobic digestion when microorganisms break down (eat) organic materials in the absence of air (or oxygen). Biogas is mostly methane (CH4) and carbon dioxide (CO2), with very small amounts of water vapor and other gases.
Detailed explanation-3: -Biogas is a combination of two-thirds of methane (CH4) and the rest is mostly carbon dioxide (CO2) with traces of hydrogen sulfide which can be enriched to produce natural gas.
Detailed explanation-4: -The anaerobic digestion process produces gas composed of methane (CH4) and carbon dioxide (CO2), known as biogas. These gases are produced from organic wastes such as livestock manure, food processing waste, etc.
