Biogas is produced through the anaerobic digestion of organic materials, such as agricultural waste, food scraps, and sewage sludge. The process produces methane (CH₄), which can be used as a renewable energy source.

Anaerobic Digestion for Biogas Production

Anaerobic digestion is a biological process where microorganisms break down organic material in the absence of oxygen. This is commonly used to convert organic waste into biogas, which is primarily methane and carbon dioxide.

Anaerobic Digestion Reaction:

C ₆H ₁₂O ₆ → 3CH ₄ + 3CO ₂

(Glucose → Methane + Carbon Dioxide)

In this reaction, glucose or organic waste is digested by bacteria and converted into methane (a usable fuel) and carbon dioxide. Biogas can then be used for heating, electricity, or as a vehicle fuel after purification (bio-methane).

Conditioning of Biogas - Conversion of Biogas to Bio CNG/CBG

Biogas conditioning is the process of transforming raw biogas into high-quality fuels like CBG (Compressed Biogas) and CNG (Compressed Natural Gas).

The purified biogas, with a methane content of 95–98%, is then compressed to 200–250 bar for storage and use. CBG offers a renewable, carbon-neutral alternative to fossil fuels, matching the performance of CNG, which is derived from natural gas. By conditioning biogas, industries and communities can reduce greenhouse gas emissions, manage waste sustainably, and contribute to cleaner energy solutions.
