Methane hydrogen sulphide and CO2

Anaerobic digestion is a bacterial process that breaks down organic material within the waste in the absence of oxygen. Municipal sewage treatment facilities also use sludge digesters. In anaerobic sludge digesters, bacteria produce a vital mixture of gases like methane, hydrogen, sulphide and carbon dioxide. 
Generally, equation for anaerobic sludge digestion is 
Organic matter + combined oxygen --> Anaerobic microbes + New cell + Energy +CH4 + CO2 +Other gases
