Anaerobic digestion (AD) is a biochemical process that uses the microbiological conversion of organic materials to generate biogas. Biogas is typically composed of 50% to 70% methane (CH4) and 30% to 40% carbon dioxide (CO2). The most simplistic design of an AD system is the solid state digester (SSD), which is able to process very high solids content materials. A SSD has the potential to be utilized in a manure management system of a beef cattle feedlot to integrate seamlessly into an ethanol, feedlot operation to capitalize on the eco-cluster concept for bioenergy production.
