Question

Which of these is the correct process of manufacturing biogas?

• A. Biomass - Digester - Anaerobic digestion - Biogas
• B. Biomass - Digester - Aerobic digestion - Biogas
• C. Biomass - Heat - Biogas
• D. Biomass - Heat - Pressure - Biogas

Answer 1

The correct option is A

Biomass - Digester - Anaerobic digestion - Biogas

In a biogas plant, the organic matter which is mostly composed of cow dung water called slurry is fed to the digester (a sealed chamber with no oxygen) where anaerobic micro organisms break down complex compounds and generate biogas.
