A basic theoretical thermodynamic calculation, using starch (C10H6O5)x as a feed stock, shows that the available energy from turning starch into methane and carbon dioxide is 884 kJ/kg. If the same starch is turned into carbon dioxide and water, the energy released is 17,371 kJ/kg. Anaerobic digestion therefore releases only 5% of the energy of aerobic digestion, which is why it does not heat up the mixture.

G'day All, How much energy is given out in the digesters as a result of anaerobic reaction? I can't seem to get any publication with enough details on this. I would like to know the temperature rise that would be caused by the reaction. -- Best Regards, Paul S. Muthui Research & Development Engineer Schutter Energy Ltd.
