High-solid anaerobic digestion system provides power to American River Packaging
The Clean World Organic Waste Conversion Center (developed by Clean World Partners) is based on anaerobic digestion (AD) technology developed at UC Davis. It converts food waste, agricultural residue and other organic waste into renewable energy, fertilizer and soil enhancements.
Each day this anaerobic digester will convert 7.5 tons of food waste from Campbell Soup and other Sacramento regional food producers, along with a half-ton of unrecyclable corrugated material from American River Packaging, into natural gas. The natural gas will be used to generate approximately 1,300 kWh of renewable electricity per day, supplying about 37 percent of American River Packaging’s electricity needs.
“Installing the Clean World system at our facility makes sense from an environmental and economic standpoint,” said Tom Kandris, CEO of American River Packaging. “We now provide our own plant with clean energy which comes from scrap byproduct that we’d otherwise pay to send to landfills.”
With this system, more than 2,900 tons of waste will be diverted annually from landfills, and 1,000 tons of compost and soil will be produced each year for regional agriculture and horticulture applications.
“Our technology is revolutionary because it enables businesses and communities to tap into their own waste streams to generate affordable renewable energy,” said Michele Wong, Clean World Partners chief executive officer. “We expect it will lead rapidly to more widespread implementation of commercial organic waste conversion solutions.”
The Clean World system installed at American River Packaging is the product of a public-private partnership. Support for research and feasibility studies was provided by UC Davis, CalRecycle and the California Energy Commission, with private investment and funding from the facility’s construction installation.
The City of Sacramento also played a key role in the project’s implementation through its project-approval and permitting role.
“This project puts the City of Sacramento at center stage in the development of new, globally significant clean technologies,” said Wong. “Businesses and communities around the world are already showing interest in what we’ve developed here.”
