Anaerobic digestion is a natural process in which different microorganisms of the biological kingdoms of Bacteria and Archaea work together to convert organic compounds through a variety of intermediates into biogas, a mixture of methane and carbon dioxide and small amounts of hydrogen sulfide and hydrogen. This ancient process, brought about by living species long before the presence of oxygen in the atmosphere, is presently gaining an increased interest because of its potential in the treatment of solid organic waste, sludge, and wastewater.
