Bio CNG Plant Unit
This project profile covers the establishment of a Bio-CNG plant unit that processes organic waste such as crop waste, animal waste, and municipal solid waste into purified compressed bio-methane. The plant utilizes anaerobic digestion and multi-stage membrane purification systems to produce clean, high-calorific fuel.

Compressor to compress Bio-NG into Bio-CNG
Manufacturing process
- Procure organic waste and animal manure and store them appropriately.
- Crush food waste and mix with cow dung and water inside a slurry tank with an agitator.
- Pump the uniform slurry into the anaerobic digester to decompose waste and produce biogas.
- Extract biogas from the digester dome and collect it in a gas receiver.
- Dehumidify and reheat the biogas before passing it through a hydrogen sulphide scrubber.
- Compress the partially purified biogas and feed it into a three-stage membrane purification system to separate carbon dioxide and obtain methane-rich Bio-NG.
- Inject THT gas into the Bio-NG stream for odor detection.
- Compress the Bio-NG using a high-pressure compressor to generate Bio-CNG.
- Fill the finished Bio-CNG into high-pressure storage cylinders or cascades for distribution.
Market
Bio-CNG can be used to replace conventional CNG for automotive fuel in buses and tractors, serve as an eco-friendly cooking fuel, and power street lighting or generators.
