Commercial Bio-CNG & CBG Plant Setup with Napier Grass | UNNATI 9 GROUP
Turnkey CBG Project Consultancy, DPR, Napier Grass Feedstock Planning & Bioenergy Solutions
UNNATI 9 GROUP provides Bio-CNG and CBG plant setup consultancy for farmers, entrepreneurs, investors and agribusinesses developing commercial bioenergy projects. We integrate Napier Grass cultivation, biomass feedstock planning and anaerobic digestion systems to support the development of sustainable compressed biogas projects.
Our end-to-end services include CBG project feasibility studies, Detailed Project Reports (DPR), plant planning, Napier Grass cultivation guidance, biomass supply planning, technology selection, project implementation and operations support.
We also provide guidance on applicable government schemes, regulatory requirements, project financing and potential off-take arrangements, helping clients plan commercially viable and scalable Bio-CNG and CBG projects.
What is a Bio-CNG Plant?
A Bio-CNG plant converts organic biomass such as Napier grass into biogas through anaerobic digestion, which is then purified and compressed to produce Bio-CNG (Compressed Bio Gas).
Bio-CNG can be used for
🚜 Agricultural machinery
🚗 Vehicles as fuel
🏭 Industrial energy
🍳 Cooking gas
⚡ Electricity generation
It is considered a green alternative to fossil fuels.
Why Use Napier Grass for Bio-CNG?
Key Advantages
🌾 Extremely high biomass yield
🌱 Harvestable 5–6 times per year
💧 Low water requirement
🌍 Environment friendly
💰 Provides regular farmer income
🔥 High methane production potential
Napier grass can produce 250–350 tons biomass per hectare per year, making it ideal for continuous gas production.
⚙️ Bio-CNG Production Process
🌱 1. Napier Grass Cultivation
Napier grass is cultivated on agricultural land as a high-biomass energy crop. It grows quickly and can be harvested every 45–60 days, ensuring a continuous supply of raw material for the Bio-CNG plant.
✂️ 2. Chopping & Feeding
After harvesting, the Napier grass is chopped into small pieces using a chaff cutter or biomass shredder. The prepared biomass is then fed into the anaerobic digester for gas production.
🦠 3. Anaerobic Digestion
Inside the digester, microorganisms break down the organic biomass in the absence of oxygen. This biological process produces biogas, which mainly contains methane (CH₄) and carbon dioxide (CO₂).
🔬 4. Gas Purification
The raw biogas goes through a purification system where impurities such as CO₂, hydrogen sulfide (H₂S), and moisture are removed. This step upgrades the gas quality for fuel use.
🟢 5. Bio-CNG Compression
The purified biogas is compressed at high pressure to produce Bio-CNG (Compressed Bio Gas). The gas is then stored in cylinders or cascades for use as a clean renewable fuel.
🌿 6. By-Product: Organic Fertilizer
The remaining slurry from the digester becomes nutrient-rich bio-organic fertilizer. This natural fertilizer improves soil fertility and supports sustainable farming practices. ♻️🌾
