New biogas plants start up on either side of the US

Two new biogas plants have been recently completed in the US, one in California and the other in Washington. Sacramento-based waste-to-power business Cleanworld has brought online what it claims to be the country’s largest commercial-scale anaerobic digestion system. The system is set to convert 25 tonnes of food and organic waste materials a day into electricity and renewable natural gas, with a further 30,000 tonne-per-year scale-up planned for January. And beef producer Agri Beef has added a biogas plant to its beef processing facility in Toppenish, Washington to help power onsite operations. Methane captured and processed in an anaerobic lagoon has replaced almost 20% of the facility’s natural gas needs.
