BioDigester named “International Bioenergy Project of the Year”

A biodigester owned by US anaerobic digestion company CleanWorld has won the “International Bioenergy Project of the Year” at the Renewable Energy World Power Engineering Awards Gala in Orlando, Florida.

The Sacramento BioDigester, the largest anaerobic digestion system of its kind in North America, converts 25 tons of food waste per day into various forms of renewable energy including heat, electricity, and natural gas. The company plans to build a Phase II facility to expand its size three-fold, to 100 tons per day of food waste, or nearly 40,000 tons per year.

The facility will produce 700,000 diesel gallons per year of renewable CNG and prevent the release 18,000 tons of CO2 into the atmosphere, while also producing eight million gallons a year of organic soils and fertilizer products for Sacramento area farms and generating one million kilowatts of electricity to be used to power the facility and the adjacent fuelling station. The fuelling station produces the only commercially available fuel that has negative carbon intensity in the US, meaning it destroys more carbon than it creates.

CleanWorld is currently building UC Davis Renewable Energy Anaerobic Digester (READ) in a former landfill, which will convert 50 tons per day, nearly 20,000 tons per year, of food waste into electricity to power the University of California, Davis campus. In 2012, the company also placed into service the American River Packaging BioDigester in Natomas, California, which produces electricity for the box manufacturing company. “Anaerobic digestion of food waste is the future of energy,” Wong said. “And CleanWorld, as the North American leader in this industry, will continue to lead the charge.”

CleanWorld’s anaerobic digestion technology, developed at the University of California, Davis, and fabricated and constructed in California, uses natural microbes to break down organic waste, generating biogas and other forms of renewable energy.
