Anaerobic digestion produced biogas is an environmentally friendly, renewable fuel. Before use, it is important to clean or upgrade the gas to increase its heating value and to make it functional in some gas appliances such as engines and boilers.
Biogas includes methane, carbon dioxide, and other trace gases. The production of biogas happens when manure is kept in an anaerobic environment. The produced methane can be utilized right away to create heat or electricity, or go through a cleanup process to create renewable natural gas for the grid or fuel.
