Special Guest Speaker: UCD Ribbon Cutting April 22nd.

On April 22nd, EARTH DAY, CleanWorld will celebrate with UC Davis the official ribbon cutting of our new (commissioned December 2013) Renewable Energy Anaerobic Digester (READ) facility. Special guests include Congressman John Garamendi, Senator Lois Wolk, and Assemblymember Mariko Yamada, who will be presenting the University with Resolutions from both houses of the California State Legislature. Invited notables also include Congresswoman Doris Matsui, a longtime supporter of CleanWorld and clean technology in the region.

FARM TO FORK TO FUEL

This project is unique to the country, located in the heart of the Farm to Fork Capital of the World, and is a closed-loop AD solution that helps the region, the City of Davis, and the University achieve zero waste goals. This BioDigester will be fed by the campus’ own food waste and other agricultural and green wastes in and surrounding the University, and from commercial, regional organic waste producing partners. At the end of this closed-loop project is what is called effluent – this liquid and solid material will go back onto area farms and be made into other fertilizing products, such as that which we distribute today through EcoScraps.

This Farm-to-Fork-to-Fuel facility is a global example of what’s possible in zero waste economies, and in climate resiliency and organic waste management leadership, where the bridges between research and academic discovery and commercialization have been built and crossed. This is the new model for Farm-To-Fork-To-Fuel for organic waste repurposing, the new “Zero Waste” value chain: food grown locally, consumed locally, and anaerobically converted to valuable, sustainable “fuel” byproducts locally, in the form of green electricity (or renewable natural gas RNG), soil enhancements, cleaner air, and cleaner land.

CLOSING THE LOOP ON ORGANICS

CleanWorld currently also operates two additional anaerobic digester facilities in the Capital Region of California that turn food and agricultural waste into electricity, negative carbon vehicle fuel, and digestate—the liquid and solid material that’s left after the organic waste has been digested. This material is rich in microbial activity, nutrients, including nitrogen, phosphorous, and potassium, making it an excellent soil amendment. Significant interest has been generated around fertilizer and soil amendment products developed from digestate because they naturally retain beneficial microbes and nutrients, are inherently more environmentally friendly than petroleum-based fertilizers, and contribute to the longevity of California farmlands.

Designed and built by CleanWorld, using innovative, proprietary anaerobic digestion (AD) technology developed and patented at the University of California, Davis (UCD), the UCD BioDigester represents a unique public-private partnership, enabling the university and its surrounding region to be a direct recipient of the many economic and environmental benefits of this third commercial high-solids AD facility of its kind in North America. CleanWorld continues to advance critical research in the commercialization of the effluent from our BioDigesters with UC Davis and regional farming partners, where as we cut the ribbon on this project, and wrap up soon to be announced commercial organic feedstock agreements in the region, CleanWorld is also launching their marketing partnership with EcoScraps, the distribution partner for our 3-3-3 liquid fertilizer made from the effluent. You can buy the 3-3-3 product online today.

Made possible by technology invented by Dr. Ruihong Zhang, a UC Davis researcher and professor, READ was commissioned in January of 2014, and built to completion in less than six months. It represents CleanWorld’s third commercial AD facility in less than two years. CleanWorld’s digesters are pre-fabricated, value-engineered, modular-by-design, and require minimal additional water for solid waste digestion – making the system less expensive, quicker to build, and smaller by its footprint.

Project Benefits:

* Gives the university an environmentally and economically sound alternative for disposing of organic waste.
* Generates 5.6 GWh of renewable electricity and diverts 20,000 tons of organic waste from local landfills annually.
* Reduces greenhouse gas emissions by 13,500 tons annually, as well as produces over 4 million gallons of fertilizer and soil amendments – enough to provide low cost, natural fertilizers for 145 acres of California’s farmlands every day.
* The university is a significant partner for testing the benefits of its digester effluent, which strengthens the opportunities for commercial applications of the nutrient byproducts of its AD facility and organic waste streams.

Project and Technology Innovation:

The high loading rate and high-solid digestion capability of CleanWorld’s BioDigester technology make it particularly beneficial to institutional, commercial, and municipal solid waste producers. The processing system design – a patented three-stage proprietary system – allows for the higher rate capability and a greater yield of methane, among many competitively unique processing benefits. This facility blends with the landfill gas from the now closed UCD landfill to produce renewable electricity, which feeds the university’s West Village micro grid and its electric car charging stations.

Project financing: provided by First Northern Bank, CalRecycle, and the U.S. Department of Energy. Key project partners include Otto Construction and University of California, Davis. Additionally, Carson Development Company, Peabody Engineering, TSS Consultants, Regatta Solutions, Capstone Turbine Corp., and Vasko Electric have played key roles in the development of the READ facility.
