Clean World Partners Grant For Pre-Development Activities for a Biomethane Production Facility

<< Return to Projects

Through Energy Commission funding, Clean World Partners, LLC has demonstrated ways to turn food and green waste into usable natural gas at the Sacramento South Area Transfer Station (SATS) at 8550 Fruitridge Rd in Sacramento, CA. The Energy Commission grant allowed Clean World Partners, LLC to evaluate the technical, economic and environmental impacts of the upscale commercial grade 100 tons per day anaerobic digestion at the SATS facility; the evaluations of commercial capabilities were done at the American River Package 8 tons per day anaerobic digestion facility at 4225 Pell Dr in Sacramento, CA. For this pre-development project, tasks included site assessment, technical and economic feasibility studies, feedstock performance and material assessments, feedstock and waste management plans, and engineering design and ancillary equipment review.

The SATS facility will use an anaerobic digester system known as Anaerobic Phased Solids (APS) that uses less energy to operate than other systems. The innovative design has fewer moving parts, is highly scalable, uses commercially available components and minimizes pre-treatment time of the feedstock. The Sacramento facility will serve as a model to other landfill operations around the country. Besides biomethane, other products created by the facility will include renewable hydrogen, liquid fertilizer, compost and clean water.

Grant Amount

The Energy Commission is providing $1,315,800.

Match Funding

$1,383,569.00 from the project's participants.

Project benefits:

California landfills approximately 16 million tons of organic waste each year, a valuable resource that could become energy instead of decomposing trash. Experts estimate that methane emissions from organic waste decomposing in landfills are 72 times more harmful than CO2 emissions created by automobiles. The Energy Commission grant funded studies for a biomethane production facility that is expected to produce more than 71 million standard cubic feet of compressed natural gas each year. The fuel will be used by the Yolo County Transit District's CNG bus fleet and will meet over two-thirds of its annual CNG demand. This natural gas will displace 584,000 gallons of gasoline annually and reduce greenhouse gas emissions by 85 percent when compared to diesel. In addition to producing energy, the project keeps 36,500 tons of organic waste out of local landfills each year.
