Compressed Natural Gas (CNG) Fuel for Industrial Wastewater - Water and Wastewater
Use waste from food processing industries to feed an aerobic digester and generate biogas for vehicle fuel. Industrial processes, particularly those from the food processing industry, generate a great deal of organic waste, which can be used as a feedstock for an anaerobic digester.
Food waste can have as much as 15 times the methane production potential of dairy cattle manure, so it makes an excellent feedstock. Also, food waste can be combined with manure to improve methane generation in a process known as co-digestion.
Different digesters are used, depending on the moisture content of the waste feedstock. Biogas is used for heat or other energy production when produced from industrial wastes, and is also a great source of BioCNG vehicle fuel.
