ANAEROBIC DIGESTION
The microbial degradation of organic
compounds, in the absence of oxygen,
to biogas – a mixture of:
• Methane (50 to 70%)
• CO2 (30 to 50%)
• trace amounts of H2, NH3, and H2S.

Biogas is a sustainableenergy solution that is:
• Renewable
• Carbon dioxide neutral
• Locally based
thereby protecting the environment, creating jobs and strengthening local economies.
