- Bio-CNG is a purified form of biogas with over 95% pure methane gas
- It is similar to natural gas in its composition (97% methane) and energy potential
- While natural gas is a fossil fuel, bio-CNG is a renewable form of energy produced from agricultural and food waste
- A typical bio-CNG station comprises a biogas purification unit, a compressor, and a high-pressure storage system
- Bio-CNG is being looked at as an environment-friendly alternative to diesel
- Why in news? Government planning to open Bio-CNG plants
