Bio-CNG: Clean Energy for a Sustainable Future
Bio-CNG (Compressed Biogas) is a renewable, eco-friendly fuel produced from organic waste such as agricultural residue, food waste, animal manure, and municipal solid waste. With properties comparable to conventional CNG, Bio-CNG offers a reliable and scalable alternative that supports energy security, waste management, and climate goals—making it a key pillar in India’s clean energy transition.
What is Bio-CNG?
Bio-CNG is produced by upgrading biogas generated through anaerobic digestion of organic waste. During this process, biodegradable materials are broken down by microorganisms in the absence of oxygen, producing biogas primarily composed of methane and carbon dioxide. After purification and compression, the enriched methane becomes Bio-CNG, suitable for use in vehicles, industries, and commercial applications.
How Bio-CNG is Produced
Feedstock Collection – Organic waste from farms, food processing units, households, and municipalities is collected.
Anaerobic Digestion – The waste is processed in digesters where microorganisms produce biogas.
Biogas Upgrading – Impurities such as CO₂, moisture, and hydrogen sulfide are removed.
Compression & Storage – Purified gas is compressed to CNG standards for distribution and use.
By-Product Utilization – The leftover digestate is processed into nutrient-rich organic fertilizer.
