Biogas in Wisconsin: Status, opportunities, and challenges
Biogas is a clean renewable gas locally produced from organic waste materials such as food waste, agricultural residues and animal manure, energy crops, industrial organic waste and sewage sludge. Biogas production involves a process called “Anaerobic Digestion” in which bacteria and other microorganisms break down and digest carbon rich organic materials in the absence of oxygen. This generates a mixture of methane and carbon dioxide, called biogas.
