Meaning and Definition
A type of fuel gas produced by the anaerobic digestion or fermentation of organic matter, such as manure, sewage, or plant material.
The general term for a mixture of gases, primarily methane and carbon dioxide, generated by the biological breakdown of organic material in the absence of oxygen. It is considered a renewable energy source and can be used for heating, electricity generation, or as a vehicle fuel.

FAQ
Frequently Asked Questions
No. Biogas is produced renewably from organic matter, while natural gas is a fossil fuel extracted from underground reserves. Both contain methane, but their sources and environmental impacts differ.
Biogas can be burned for heat, used in gas engines to generate electricity and heat (cogeneration), upgraded to pure methane (biomethane) for vehicle fuel, or injected into the natural gas grid.
No, when managed properly, it is considered a carbon-neutral or carbon-negative renewable energy source. It captures methane that would otherwise be released from decomposing waste, turning a potent greenhouse gas into useful energy.
Yes, small-scale domestic biogas digesters exist, often used in rural areas to process kitchen and animal waste, producing gas for household cooking and lighting.
