Every day, India produces massive amounts of organic waste. Dairy farm excrement from cattle. Leftover food from cities. Fields in Punjab, Haryana and UP burning crop residue. For most people, this is a disposal problem. For CBG project developers, it’s the raw material.
Compressed Biogas (CBG) is what you get when organic waste is digested, purified, and compressed. It works exactly like CNG in vehicles, boilers, and industrial equipment. Project developers who register under SATAT get guaranteed offtake from Oil Marketing Companies, access to government subsidies, and priority loans through NABARD and nationalised banks. A CBG plant with the right setup starts generating revenue within 6 to 12 months of project kick-off. That’s a strong business case built on waste most people throw away.
What is a CBG Plant?
A CBG plant converts organic waste into Compressed Biogas through anaerobic digestion, purification, and compression. Chemically, CBG is identical to CNG. Same pressure, vehicles, pipelines. The only difference is where it comes from. As one of the trusted cbg plant manufacturers in India, Natural CNG Fitment Pvt Ltd. supplies complete CBG plant setups from a single source, covering every stage of your production chain.
Know CBG Production Process
- Biogas Generation: Waste enters a sealed digester. Bacteria break it down over 15 to 30 days, producing raw biogas with 55% to 65% methane along with CO2 and other impurities.
- Purification: A purification unit removes CO2, hydrogen sulfide, and moisture. Methane climbs past 90%. Raw biogas becomes CBG-grade fuel.
- Compression: A multi-stage compressor raises purified gas to 250 bar, the pressure needed for storage and vehicle filling.
- Storage and Dispensing: Compressed CBG moves into CNG cascade storage banks and flows to dispensers, industrial lines, or mobile cascades headed to remote locations. We’re one of the best gas cylinder cascade manufacturers in India, specialized in offering a wide range of high pressure cng cascade, cbg biogas, hydrogen gas and industrial gases.
What are the Applications of a CBG Plant
- Vehicle fuel for retail CNG stations and captive fleet fuelling
- Industrial fuel for boilers, furnaces, and dryers replacing diesel and LPG
- Power generation through gas engines producing on-site electricity
- SATAT offtake through long-term agreements with IOCL, BPCL, and HPCL
- City gas distribution through blending CBG into CGD networks
- Organic fertilizer from digestate as a reliable second revenue stream
Benefits of Setting Up a CBG Plant
- Near-zero raw material cost. Waste is your feedstock. It costs nothing to source.
- Guaranteed revenue through SATAT offtake agreements with Oil Marketing Companies
- Two income streams: CBG sales and digestate fertilizer working together
- Lower waste disposal costs. Your organic waste stops being a liability.
- Reduced carbon footprint by replacing fossil fuels with clean CBG
- Energy independence for your farm, factory, or municipality
Know Government Schemes, Subsidies, and Loans
India has strong policy support for CBG projects. Most developers don’t use it fully.
SATAT Scheme: Launched by the Ministry of Petroleum and Natural Gas. Register as a CBG producer and sign a fixed-price offtake agreement with OMCs. Guaranteed buyer from day one of production.
GOBAR-DHAN Scheme: Ministry of Jal Shakti support for rural CBG projects working with cattle dung and agro waste. Provides technical and financial assistance to registered developers.
MNRE Subsidies: The Ministry of New and Renewable Energy provides capital subsidies for biogas-based projects. Subsidy amount depends on your plant capacity and project type.
NABARD Loans: Priority sector lending for SATAT-registered CBG plants through NABARD and nationalised banks at competitive interest rates.
CBG Plant Setup Cost, Sizes, Production and Land Area
As experienced CBG plant manufacturers, we supply 22 sizes from 2 TPD to 30 TPD. As a preliminary planning estimate, you can use:
| Plant Size | CBG Production | Land Area Approx. | Price Approx. |
| 2 TPD | 2 tonnes/day | 3–4 acres | ₹5-7 Cr |
| 5 TPD | 5 tonnes/day | 4–7 acres | ₹25-35 Cr |
| 10 TPD | 10 tonnes/day | 6–10 acres | ₹40-90 Cr |
| 20 TPD | 20 tonnes/day | 10–15 acres | ₹100 Cr+ |
| 30+ TPD | 30 tonnes/day | 15–25 acres | ₹150-250+ Cr |
*Feedstock requirement varies dramatically by material and plant technology.
What Actually Requires Land for CBG Plant Setup?
The plant unit itself is just one piece of the puzzle. Adequate space must be allocated for several supporting components, including:
- Feedstock receiving and storage areas
- Pre-processing and shredding units
- Digesters and gas-upgrading systems
- CBG compression and storage facilities
- Digestate and organic manure handling zones
- Internal roads, truck movement, and parking
- Utilities, administrative office, safety buffer zones, and space for future expansion
Important Note: If paddy straw or other bulky agricultural residue is part of your feedstock mix, it’s advisable to plan for the higher end of the land range – bulky residues tend to demand significantly larger storage footprints. On the other hand, wet feedstocks like press mud or cattle dung come with a different set of space requirements altogether.
CBG BIO CNG Plant Project Timeline
- Month 1 to 2: Feasibility study and site assessment
- Month 2 to 5: Engineering, civil work, and approvals running in parallel
- Month 4 to 6: Equipment installation and pipeline work
- Month 6 to 8: Testing and start-up
- Month 8 to 12: First CBG production and SATAT offtake begins
Start your approval process early. Running it after equipment arrives adds months to your timeline.
How Long Does a CBG Plant Last?
A well-built CBG plant runs for 15 to 20 years with proper maintenance. Regular compressor servicing, cascade inspection, purification filter replacement, and pipeline leak testing keep your plant producing reliably. We provide O&M and AMC services for every plant we supply.
How Much Feedstock Does a CBG Biogas Plant Need?
To produce 1 tonne per day (TPD) of sellable Compressed Biogas, a plant typically needs an input of 20–30 tonnes of wet organic feedstock daily. The exact figure depends heavily on the quality and composition of the material being used.
Feedstock Options Commonly Used
- Press Mud – A sugar mill byproduct that delivers strong methane output and requires little pre-processing.
- Cattle Dung & Animal Waste – A steady, nutrient-rich source typically pulled from nearby dairies or gaushalas.
- Agricultural Residue – Includes paddy straw, wheat straw, and maize stalks; using these also helps cut down on stubble burning.
- Energy Crops – Purpose-grown biomass like hybrid Napier grass, valued for rapid growth and high yield.
- Municipal & Food Waste – Sorted organic wet waste collected from cities.
Here’s the current picture on CBG plant subsidies in India for 2026:
Central Government GOBARdhan Scheme came on 6 August 2026, when the Union Cabinet approved GOBARdhan, the National Unified Scheme for Compressed Biogas, with a ₹23,731 crore outlay. It runs from FY 2026–27 to FY 2035–36, covering demand support, pricing, capital, pipelines, credit, and technology under the Ministry of Petroleum and Natural Gas, with the goal of increasing domestic CBG production nearly ten-fold through assured demand, stable pricing, capital assistance, pipeline connectivity, credit support, and technology development.
CBG Plant Subsidy India 2026: GOBARdhan Scheme Guide
Capital assistance: Up to ₹2 crore per tonne per day (TPD) of installed CBG capacity for eligible greenfield projects, with brownfield expansions also eligible.
Administered pricing: A CBG price of ₹2,110 per MMBTU, which the government states is equivalent to roughly ₹105 per kilogram.
Credit guarantee: This is separate from the capital subsidy — it provides guarantee coverage of up to 85% of the outstanding loan amount at default, subject to caps, meant to reduce lender risk rather than serve as an upfront cash grant.
Backed by central financial support of up to ₹10 crore per project, guaranteed long-term offtake agreements with Oil Marketing Companies, and a mandatory 5% CBG blending target by FY 2028–29, India is steadily building out a nationwide compressed biogas ecosystem.
