Bio GAS
Shaping the future with sustainable energy innovations.
Biogas to CBG
Biogas is an energy-rich gas produced by anaerobic decomposition of biomass. It is produced from waste/bio-mass sources like agriculture residue, cattle dung, sugarcane press mud, municipal solid waste, sewage treatment plant waste, etc.
Biogas Composition
CBG Production Process
From organic waste to compressed biogas - A complete sustainable energy cycle
Feedstock
Anaerobic Digester
Biogas production through anaerobic decomposition
Biogas
Raw biogas containing ~60% methane, ~40% CO2
Purification
CO2 removal to increase methane content >90%
Compressor
Compression at 250 bar for transportation
Biogas Purification
Production of biogas could be a continuous process. The utilization of biogas as an efficient energy source depends strongly on its methane concentration. Therefore, biogas purification is essential in order to have more energy per unit volume of compressed biogas and to get rid of the corrosive effect of H2S.

Methane Content
Cascade Storage & Transportation
Compressed biogas filled and transported through cascades (high pressure cylindrical vessels). For CBG delivery, 3000 litres metal cascades or higher capacity cascades are used.
Compression Process
The purified biogas with more than 90% of methane can be compressed at 250 bar, and transported in gas cylinders (cascades) for the end use.
Compression Specifications:
250 bar
3000+ litres
Safety Standards:
- IS 7285 for steel cylinder cascades
- IS 15593 for composite cascades
CBG Quality Standards
CBG has calorific value and other properties similar to CNG and can be utilized as green renewable automotive fuel. CBG supplied KEC scheme shall meet IS 16087:2016 specifications.
IS 16087 : 2016 Standard
| S No. | Characteristic | Requirement |
|---|---|---|
