CBG is the clear pathway to energy security

Geo-political volatility and fluctuating fuel prices have underscored the need for energy resilience. Through the Gobardhan scheme blending obligations, and strategic partnerships, the government is enabling growth with policy support, demand assurance, and infrastructure investment. With vast biomass resources, India holds an estimated sustainable CBG production potential accounting for 120% of the country’s natural gas demand in 2024, with 45% of that from agricultural residues alone.

Most CBG plants aren’t
running at full potential

Most CBG plants aren’t running at full potential

Most rely on cow-dung or repurposed slurry — not optimized for lignocellulosic biomass like paddy straw, napier grass, sunflower stalk, or water hyacinth — resulting in reduced efficiency and yield, hitting planned ROI and cash flows.

That's where
Greethane comes in

Through GreethaneTM, our proprietary platform, we bring technological innovation & expertise and be your trusted advisor — helping you build a profitable Bio-CNG plant.

Customized technology,
for your biomass

Our proprietary and advanced processes use specialized microbial consortia tailored to your biomass and optimized for each stage of anaerobic digestion — enabling efficient digestion and energy recovery, helping you extract the maximum energy yield. Combined with our innovative Bio-Disc technology, GreethaneTM reduces microbial washout, improves digestion efficiency, lowers HRT, and enhances plant stability.

With proprietary pre-treatment, customized AD treatment with engineering innovations, and bio-gas upgradation techniques, the output is high-quality biogas (99+% purity) with superior yield.

The digestate generated in the process is treated and optimized, refining the solubilization metrics required, generating value added products such as FOM and PROM. This organic fertiliser helps improve the soil health and improve crop yields. The separated biogenic CO2 can be used for industrial purposes, and the carbon emissions mitigation can yield carbon credits — yielding multiple revenue streams.

Paddy straw — the most overlooked biomass & energy opportunity

India generates around 120 MT of rice straw annually. Its complex lignocellulosic, hydrophobic nature, low density, and high silica content limit its use as animal fodder, CBG feedstock, or otherwise — leaving many farmers with stubble burning, with no other way to clear fields before the next harvest.

Greethane’s specialized protocol — customized pre-treatment methods, specialized microbes for every AD phase, and zero addition of cow dung or recirculated slurry — delivers a higher conversion efficiency.

The optimized digestate yields high-value NPK-fixed FOM and PROM, while purified process water drives toward Zero Liquid Discharge (ZLD), cutting the process’s water footprint.

Similar protocols are built for relevant biomass such as millet straw, napier grass, sunflower stalk, water hyacinth and other biomasses.
