The California Energy Commission (CEC) recently awarded a $6 million grant to Clean World Partners to expand its Sacramento based Organic Waste Recycling Center. Upon expansion it will become the first digestion-based Renewable Natural Gas Fueling Station and the largest commercial-scale, high solids anaerobic digestion (AD) system in the nation.

The fueling station will be powered by renewable energy from the digestion facility. Natural gas produced from the 100-ton per day digestion system would fuel approximately 320 school buses for one year. It will fuel the company’s clean-fuel fleet, as well as vehicles from area jurisdictions and agencies.
The digestion center initially will convert 25 tons of food waste per day collected by Sacramento-based Atlas Disposal Industries from area food processing companies, restaurants and supermarkets into renewable natural gas. The CEC grant will support expansion of the facility to handle 100 tons of waste per day by early 2013, which will make it the nation’s largest such system.

The expanded facility will replace 1 million gallons of diesel per year with renewable natural gas and produce 2 million kilowatt hours of electricity per year, enough to power 200 homes.

“Clean World Partners is clearly demonstrating that its waste-recycling systems can be used in a wide range of situations,” said Energy Commissioner Carla Peterman. “We’re pleased to support expansion of this new facility in Sacramento and are excited about its growing influence in the waste-recycling market.”

The two facilities combined will create 16 long-term jobs in Sacramento and generate more than $1.1 million in annual combined tax revenue for the City of Sacramento, Sacramento County and the state.

Clean World’s Organic Waste Recycling Center is based on AD technology developed at UC Davis to convert food waste, agricultural residue and other organic waste into renewable energy, fertilizer and soil enhancements.
