Turnkey EPC InfrastructureComplete engineering, procurement, and construction (EPC) for commercial Compressed Bio-Gas plants under India's SATAT initiative.
Compressed Biogas (CBG), also known as Bio CNG, is a purified renewable fuel containing more than 90% methane. It is produced through anaerobic digestion of organic materials, followed by modern gas scrubbing to remove carbon dioxide, hydrogen sulfide, and moisture.
Bio CNG plays a critical role in reducing carbon emissions and fossil fuel dependency. After purification and compression to 250 Bar pressure, it directly replaces conventional CNG, LPG, furnace oil, and diesel.

Converting organic waste to commercial fuels supports environmental, agricultural, and energy priorities.
India generates millions of tons of organic waste annually. Improper disposal leads to major open-air methane emissions, landfill pollution, stubble burning in fields, and severe environmental damage.
Bio CNG plants convert waste into clean fuel and organic fertilizers. Under government initiatives like the SATAT program, GOBAR-DHAN, Swachh Bharat, and national ESG frameworks, developers receive support to build a circular economy.
The four core phases of transforming raw feedstock residues into high-purity compressed biogas.
Raw organic waste is collected from municipal solid wastes, sugar pressmud suppliers, dairy stables, or agricultural stubble networks.
Organic matter is processed inside airtight CSTR digesters. Microorganisms ferment the raw biomass to release raw methane biogas.
Raw biogas is scrubbed to remove CO2, H2S, and moisture. Methane enrichment systems elevate purity levels above 90%.
The purified Bio CNG is compressed to 250 Bar and stored in high-pressure cascades, ready for vehicular dispatch or industrial heat supply.
Establishing a Bio CNG plant secures multiple commercial advantages and long-term financial stability.
Reduces dependence on conventional fossil fuels (coal, diesel, LPG) while ensuring long-term defense against fluctuating energy markets.
Eligible for financial benefits, viability gap funding, and priority buying guarantees under SATAT, GOBAR-DHAN, and central subsidy schemes.
