Zero Waste Energy (ZWE), Lafayette, Calif., has announced the development of two semi-mobile anaerobic digestion (AD) facilities in California that will use their SmartFerm technology. The proposed installation of the SmartFerm facilities in Napa and Monterey counties are part of ZWE's strategy to transform the way communities, businesses, and municipalities in the world's eighth-largest economy manage organic waste streams, it says.

Through a partnership agreement, Environmental Solutions Group (ESG), a Dover Industries company, will be the U.S. manufacturer of the SmartFerm digester units   designed and engineered as semi-mobile, modular plants. These modular plants use dry fermentation of organic waste streams traditionally consigned to landfill disposal. Due to space-efficient design and engineering, SmartFerm’s semi-mobile plants may be installed on sites as compact as 3,000 square feet in as little as four weeks, says the company. Operating costs are low and are offset by harvesting high-quality compost and biogas that can be converted to power or fuel from waste materials.

Because of their compact physical footprint, ZWE's SmartFerm modular plants fit within the space limitations of most commercial businesses and public institutions, the company says.

"After studying Anaerobic Digestion technologies for the last several years, Napa Recycling and Waste Services, along with the City of Napa, released an RFI (request for information) to seven different dry AD vendors,” says Greg Kelly, general manager of Napa Recycling and Waste Services. “Using SmartFerm will also allow our operations to increase volumes when we secure additional feedstock as well as provide CNG (compressed natural gas) for our fleet."

William Merry, general manager of the Monterey Regional Waste Management District, says, "For nearly four years now, we have steadily honed the district's food-scrap organics composting program that utilizes an open windrow process. We intend to expand this highly successful composting program by installing SmartFerm technology on a pilot demonstration basis.”

He continues, “The recovered energy value is exponential: the power produced from the project will be sold to the neighboring regional wastewater treatment plant to help them achieve their strategic goal of getting off the utility grid. SmartFerm goes beyond being a win-win-win for our community. It is a win for our community, our economy and our local ecology. I cannot speak highly enough about Zero Waste Energy."

Dirk Dudgeon, senior vice president of Business Development at ZWE, says, "We are very excited to have these projects be the first of many we are developing in California. The SmartFerm technology, coupled with our team's considerable expertise in project delivery, will ensure that we show the industry and our clients that there is a viable, economical solution to removing the organic fraction from the landfill."
