4th comment 😂

[@parvathy_210]

Biogas is not considered a fossil fuel because it is produced from organic matter such as agricultural waste, sewage, or food waste through a process called anaerobic digestion. This process involves the breakdown of organic materials by microorganisms in the absence of oxygen. As a result, the methane and carbon dioxide produced in biogas come from recently living organisms rather than from ancient sources like fossil fuels. Since biogas is derived from renewable organic materials and does not involve the combustion of ancient carbon deposits, it is classified as a renewable energy source rather than a fossil fuel.
