Abstract
A method of producing biogas by anaerobic digestion of organic matter may include adding cobalt, iron, and hydrochloric acid to an organic matter; bringing the organic matter in contact with biogas-producing bacteria; and digesting the organic matter under anaerobic conditions in a reactor while producing biogas and a digested sludge. A device for producing biogas may include a reactor being adapted for containing the organic matter in the form of a sludge while the sludge is digested. The device includes a feeding device for adding cobalt, iron, and hydrochloric acid to the organic matter, and an agitator for mixing the added cobalt, iron and hydrochloric acid with the organic matter. An additive, which is adapted for being added to a device for producing biogas by anaerobic digestion, may include cobalt, iron, and hydrochloric acid in an aqueous solution.
