    Anaerobic digestion Anaerobic digestion is a series of processes in which microorganisms break down biodegradable material in the absence of oxygen‚ used for industrial or domestic purposes to manage waste and/or to release energy. The digestion process begins with bacterial hydrolysis of the input materials in order to break down insoluble organic polymers such as carbohydrates and make them available for other bacteria. Acidogenic bacteria then convert the sugars and amino acids into carbon dioxide
