Approximately 150,000 GGEs Annually from Food & Beverage Waste,
CEC, Anteing $3 Million, Sees ‘A Scalable Model for Other Communities’
The City of Petaluma, north of San Francisco, is getting ready to produce biomethane fuel via anaerobic digestion at an existing wastewater recycling facility – and will use it to power garbage collection vehicles.
“The project, as a ‘closed-loop’ system, will be a scalable model for other communities with the goals of waste recovery and cutting dependence on fossil fuels,” says the California Energy Commission, which is contributing $3 million under ARFVTP, the agency’s Alternative and Renewable Fuel and Vehicle Technology Program.
The goal of the “B2B” project (biomass-to-biofuels), says CEC, is to use anaerobic digestion and state-of-the- art CNG production technology to transform high-strength waste (HSW) from food and beverage production into CNG to fuel City waste collection vehicles.
‘A Unique Opportunity’
The agency expects production of approximately 75,000 gasoline gallon equivalents of CNG from existing wastewater solids, and to double that number with the addition of HSW. Thus approximately 150,000 GGEs will be available to fuel area waste-collection vehicles.
“This project provides a unique opportunity to create a comprehensive ‘closed-loop’ local system,” CEC says. “From the collection of waste to the production of CNG to the fueling of city waste hauler trucks, this project is repeatable and scalable for other communities.
“While this project focuses on the City of Petaluma, this project can demonstrate technologies that can be ‘multiplied’ throughout the state and which will have the greatest impact on reducing overall carbon emissions and supporting local self-sufficiency.”
