What is Compressed BioCNG (CBG)?

BioCNC (CBG)

Compressed BioCNC (CBG) means the mixture of hydrocarbon gases and vapours consisting mainly of Methane in gaseous form, which has been produced by the decomposition of animal and plant waste, purified and compressed for use as an automotive fuel and industrial application.

Biogas can be compressed after removal of carbon dioxide and hydrogen sulphide, the same way as natural gas is compressed to CNG, and used to power motor vehicles.

Irrespective of technology, producing CBG from biomass involves a two-pronged approach:

Biogas is produced through anaerobic decomposition of biomass.
Since biogas contains 55 to 60 per cent methane, 40 to 45 per cent carbon dioxide (CO₂) and trace amounts of hydrogen sulphide.
The second process involves purifying the gas to remove carbon dioxide and hydrogen sulphide gases to prepare CBG.

Why Choose CBG

Benefits of Compressed Bio Gas (CBG)

🌿

Organic Renewable Energy

Compressed Bio Gas (CBG) is produced from organic waste material, making it a great renewable energy source. It also reduces use of fossil fuels.

🔥

Methane to Energy

CBG production captures methane – a potent greenhouse gas from decomposing organic matter. When used as a fuel, CBG is a great alternative to traditional fossil fuels like diesel, significantly reducing carbon emissions.

💰

Biogas Economic Opportunity

CBG production and distribution create a new business opportunity, especially in rural areas. It can generate new job opportunities. CBG reduces energy costs which is considered to great financial alternative.

♻️

Clean Fuel Cycle

The anaerobic digestion process used to produce CBG creates a byproduct called digestate, which is a nutrient-rich organic fertilizer.

Comparison

CBG vs CNG

Chemically, CBG is the same as CNG — both are compressed methane and have almost the same calorific value.

Aspect	CBG (Bio-based)	CNG (Fossil-based)
Main Component	✓ Compressed Methane	Compressed Methane
Calorific Value	✓ Almost identical to CNG	~47 MJ/kg
Source	✓ Any biomass (organic waste)	By-product of petroleum
Renewable?	✓ Yes — 100% renewable	No — fossil fuel
Carbon Footprint	✓ Carbon-negative	Carbon-positive
Distribution	✓ Cylinders or pipelines	Cylinders or pipelines
Vehicle Compatibility	✓ Can directly replace CNG	Standard CNG vehicles

Circular Economy

CBG & Its By-products

CBG and its by-products hold the chance for a circular economic growth.

🌾

Silica-rich Digestate

Rich source of silica that not only aids in the growth and yield of crops but also bestows immunity against many diseases
Prevents toxic material uptake by plants such as arsenic, cadmium, lead and other heavy metals
Can help reduce the requirement of chemical fertilisers

💨

CO₂ Recovery

CO₂ can be tapped while purifying the biogas
Used to produce liquid or solid CO₂
High demand for food preservation applications
Used in fire extinguishers and industrial processes
