Anaerobic digestion is a natural process that converts the organic carbon.
Anaerobic digestion is a natural process that converts the organic carbon contained in manure or other feedstocks (e.g. organic waste). Biogas is produced when the organic matter in manure decomposes in the absence of oxygen (i.e. anaerobic). Biogas typically contains approximately 60 to 70% methane with the balance comprised primarily of carbon dioxide and other trace gases. The potential for generating biogas is greatest from livestock operations that use liquid or slurry manure management systems, generally swine and dairy operations.
In addition to providing a proven mechanism to produce and capture methane to generate electricity, the benefits of an anaerobic digester for a livestock operation are numerous. These direct and indirect benefits include enhanced nutrient management options, odor control, improvements in air and water quality and a reduction in Green House Gas emissions from the farm.
