What is a Compressed Bio Gas (CBG) Plant?
A compressed biogas (CBG) plant is a renewable energy facility that uses anaerobic digestion to convert organic waste such as animal dung, agricultural residue, sugarcane press mud, food waste, municipal organic waste, and sewage sludge into high-purity methane gas. In the absence of oxygen, naturally occurring bacteria degrade organic matter to produce biogas.
Biogas in its raw form contains a variety of gasses that prevent its direct use as a fuel. Compressed Bio Gas (CBG) is created by purifying raw biogas to remove pollutants such as hydrogen sulfide (H₂S), carbon dioxide (CO₂), moisture, and other contaminants, and compressing it. The finished product comprises 90-95% methane (CH₄), making it clean, energy-dense, and efficient.
CBG shares features and performance characteristics with compressed natural gas (CNG) and can be utilized directly in cars, industrial boilers, power production systems, and commercial applications. Because it is made from renewable organic waste, CBG reduces greenhouse gas emissions, improves waste management, and aids India’s transition to sustainable energy.
Why India Needs Compressed Bio Gas Plants Right Now
Rising Energy Demand Across the Country
India is among the world’s fastest-growing major economies, and its energy consumption is climbing steadily. According to estimates by the Ministry of Petroleum and Natural Gas (MoP&NG), the country holds proven reserves of 763 Million Metric Tons (MMT) of crude oil and 1,488 Billion Cubic Meters (BCM) of natural gas.
Heavy Dependence on Fuel Imports
Despite these reserves, India currently imports nearly 77% of its crude oil needs and around 50% of its natural gas requirements. This heavy reliance on imports puts pressure on foreign exchange reserves and exposes the economy to global price volatility. To address this, the government set a target of reducing fuel imports by at least 10% by 2022 and raising the share of gas in India’s overall energy mix from 6.5% to 15% — against a global average of 23.5%.
CBG is a direct and scalable solution to bridge this gap.
One of the biggest advantages of a CBG plant is the wide variety of organic feedstock it can process. In India, the following materials serve as primary inputs:
- Agricultural Residue — paddy straw, wheat straw, sugarcane bagasse
- Animal Manure — cattle dung, poultry litter, pig waste
- Sugarcane Press Mud — byproduct of sugar mills
- Municipal Solid Waste (MSW) — organic fraction of urban garbage
- Distillery Spent Wash — liquid waste from alcohol and ethanol plants
- Sewage Treatment Plant (STP) Waste — sludge from urban sewage systems
- Food & Horticulture Waste — rotten vegetables, food scraps, market waste
- Dairy & Poultry Processing Waste — effluents from dairy and poultry units
- Industrial ETP Organic Waste — from food processing and beverage industries
India’s estimated CBG production potential from all these sources combined is approximately 62 MMT, with a bio-fertilizer (bio-manure) co-production capacity of around 370 MMT.
Market Size and COVID-19 Impact
The global biogas market was valued at USD 24.03 billion in 2020. While the COVID-19 pandemic caused an estimated 5.8% decline that year compared to the average annual growth rate between 2017 and 2019, the market has rebounded strongly and continues to expand worldwide.
How Europe Is Leading the Way
Countries like Germany, Italy, the United Kingdom, France, and Switzerland have built robust policy frameworks, education programs, and technology ecosystems to accelerate biogas adoption. In these nations, the most common application of biogas is injection into the local natural gas grid, followed by electricity generation and use as vehicle fuel — either in pure form or blended with natural gas.
India's Growing CBG Market
India’s CBG sector is witnessing increasing government support, private investment, and institutional interest. With a massive and diverse feedstock base across rural and urban areas, India is positioned to become a major global producer of compressed bio gas in the coming decade.
Plant Capacity Categories
CBG plants can be established across a range of production capacities depending on the availability of feedstock and investment size:
| Plant Scale | CBG Output Per Day |
|---|---|
| Small Scale | 2 Ton / Day |
| Medium Scale | 5 – 10 Ton / Day |
| Large Scale | 10 – 50 Ton / Day |
Key Machinery and Infrastructure Required
Setting up a CBG plant involves the following major components:
- Feedstock collection, handling, and storage system
- Pre-treatment unit (size reduction, slurry preparation)
- Anaerobic Digester (primary biogas production vessel)
- Desulfurization unit (H2S removal)
- CO2 scrubbing / purification system
- Gas compressor and cascade storage
- Cylinder filling and dispensing station
- Bio-fertilizer processing and packaging unit
- Effluent treatment and water recycling unit
- SCADA / monitoring and control system
Land and Utility Requirements
- Land: Minimum 1–2 acres depending on plant capacity
- Water: Continuous supply for slurry preparation and cooling
- Power: Grid connection or captive power for compressors and auxiliaries
- Road Access: Essential for feedstock supply and CBG distribution
Estimated Project Cost
The total project cost for a CBG plant varies based on capacity. A medium-scale plant of 5 Ton/Day capacity typically requires:
- Civil & Structural Works: ₹50 – 80 Lakhs
- Plant & Machinery: ₹1.5 – 2.5 Crores
- Working Capital: ₹25 – 50 Lakhs
- Miscellaneous & Pre-operative Expenses: ₹10 – 20 Lakhs
Revenue Streams
A CBG plant generates income through multiple channels:
- Sale of CBG to OMCs or retail customers
- Sale of Bio-Fertilizer (fermented organic manure) to farmers
- Carbon Credits from certified carbon reduction programs
- Gate fee income from waste processing contracts with municipalities
Profitability Indicators
- Break-even Period: Typically 3 to 5 years
- Return on Investment (ROI): 20% to 35% depending on feedstock cost and CBG selling price
- Net Profit Margin: Ranges from 18% to 28% at optimal capacity utilization

Frequently Asked Questions
How is CBG different from CNG?
CNG is derived from fossil natural gas extracted from underground reserves. CBG, on the other hand, is produced from organic waste and biomass through anaerobic digestion. Both have similar energy content and can be used interchangeably, but CBG is renewable, carbon-neutral, and locally produced.
Is a CBG plant profitable in India?
Yes. With government-backed offtake through the SATAT scheme, stable demand from OMCs, and additional income from bio-fertilizer and carbon credits, a CBG plant can achieve healthy returns within 3 to 5 years of operation.
What subsidies are available for a CBG plant?
Depending on the state and plant size, entrepreneurs can access subsidies under PMEGP, NABARD, and various state renewable energy programs. Sharda Associates assists clients in identifying and applying for the most relevant schemes.
How long does it take to get a project report from Sharda Associates?
A fully customized, bankable project report is typically delivered within 5 to 7 working days after receiving all necessary inputs from the client.
