The chemical characteristics of Bio-CNG and CNG are almost similar, this is because both the gases contain the same value of methane and calorific. But the method of making both of them is completely different and both are made from completely different substances or you can say chemicals. Bio-CNG is mostly used in rural areas for cooking and for producing electricity. On the other hand, CNG is used as fuel in vehicles and it is a by-product of the petroleum industry. What is the difference between Bio-CNG and CNG, how are these two gases made and where can they be used, we will discuss these topics in today’s blog.

What is required to produce Bio-CNG?
Bio-CNG is made by breaking down organic waste generated through biological processes. In the decomposing process, it is kept in mind that even a little oxygen should not reach the mixture. Biogenic waste is a general term used to represent waste produced from plants and animals.
Waste Produced From Farming
- Paddy Straw
- Fodder Crop
- Napier Grass
- Solid Organic Waste
- Municipal Solid Waste
Waste Produced From Animals
- Dairy Farms
- Poultry Farms
- Other Animal Husbandry
- Plant waste/ Farm Waste
How Is Bio-CNG Different From CNG?
If we see which chemicals both gases are made of, then both are made of almost similar substances like methane and calorific. One thing you people should know is that CNG is a by-product of petroleum but Bio-CNG can be made from any biomass such as crop remnants, cattle dung, sugarcane press mud, municipal wet waste, or chemicals produced by factories or sewage treatment plants.
If you have a car that runs on CNG and you see a Bio-CNG fuel station on the way, then you can get refueled from there without any hesitation. Because Bio-CNG is the same as CNG

Advantages Of Bio-CNG
Every country imports and exports from other countries. Whatever is needed in a country, that country buys it from another country and this is called import-export. My motive behind explaining all this is that you should understand that if Bio-CNG is made in India, then India will not have to buy fuels from other countries.
The solid scraps from compressed biogas can be used as fertilizer. According to the research, this fertilizer, made from a byproduct of rice production at harvest, can increase crop yields by 20 percent. Another by-product of compressed biogas is CO2, which can be made into liquid or solid form. This CO2 is in high demand for keeping food fresh and for use in fire extinguishers.
