TURNING FOOD WASTE INTO RENEWABLE ENERGY
Through unique, innovative technologies and anaerobic digestion, the San Bernardino Waste-to-Energy project converts pre-consumer food waste into renewable resources that not only diminish solid landfill waste, but reduce organizations’ carbon footprint and help achieve increasing sustainability goals.
Recovered resources such as clean industrial water, organic liquid fertilizer, biogas and electricity will aid in meeting stringent California requirements, create nutrient-rich, carbon-based organic good-grade fertilizer and generate renewable power to be delivered to Southern CA Edison power grid via a utility interconnection facility.
Diverted waste results in significant cost savings and reduced tipping fees for haulers, food waste generators and municipalities. BioStar Renewables manages and facilitates all aspects of the process — from collection and pre-processing to digestion and generation — spearheading long-term agreements that make achieving sustainability goals a seamless reality.
HOW IT WORKS
Beginning in 2020, the San Bernardino Waste-to-Energy project will divert 93,850 tons of pre-consumer food waste from the Cochella and Lambs Canyon landfills each year. As a result, 85,000 gallons per day or 31,025,000 gallons of food waste per year will create:
21,637,200 kWh of Electricity
Power for 200 homes
849,000 Gallons of SuperSix™ Fertilizer
18,250 Tons of Compostable Fiber
19,876,800 Gallons of Clean Water
Industrial reuse per year
Greenhouse Gas Emission reductions equivalent to:
Avg. passenger vehicle
of gasoline consumed
Energy per year
of coal burned
The City of San Bernardino is home to over 217,000 persons while San Bernardino County has a population of approximately 2.2-million people. The amount of food waste generated is significant and has put stress on the traditional methods of disposal such as landfills, composting facilities, and municipal solid waste facilities.
With recent studies indicating that approximately 36-million tons of food waste goes un-utilized and only about 3% of this food waste volume is recovered — the project will prove beneficial in the form of energy, nutrient, and carbon recovery as well as composting. If not, most food will end up in landfills or other disposal methods that provide little to no value to the community.
Developed on a 5.42-acre site, the San Bernardino Waste-to-Energy project goal is to provide a valuable facility for resource recovery, energy production, and financial benefits to the region by utilizing food waste resources as feedstock — producing beneficial products and materials.
The facility accepts pre-consumer food waste and processes the waste to produce several beneficial products and materials — with the development of a food-waste-to-energy digester facility utilizing anaerobic digestion, gas capture and processing, and electricity production from gas-powered generators using the methane-rich biogas.
The facility plans to have two digesters, each with a liquid capacity of approximately 1.8-million gallons and additional space available for the expansion of future digesters, helping to produce approximately 2.6 MW of electrical power using the biogas-powered engines. The exhaust from the engines will be treated to meet strict California air quality standards as well as noise restriction requirements. Heat will be recovered from the engines and recycled to maintain optimum temperatures in the digesters to maximize efficient operational conditions.
Finally, the project will be equipped with a 2.6MW utility grid interconnect. Two (2) 1.3 MW engine generators will be installed and the Project is to be operated to produce enough biogas to fuel the engine generators up to 2.6 MW. The project is supported by a 20-year power purchase agreement with Southern California Edison. The site layout is designed to handle additional feedstocks to further increase volume revenue, while sending excess biogas to heat recovery or to the flare.
While some of the outputs are valuable and have immediate beneficial use, others, such as air emission and effluent to sewer, require additional treatment to meet current air and water standards. The below graphics outline the project’s inputs and outputs.

SUEZ is a large international water and wastewater solutions company with extensive experience in many California projects, including those involving anaerobic digestion. The SUEZ team brings the experience of both the local industrial operations as well as international experience with a broad range of anaerobic digestion processes and the proprietary MONSAL technology. CleanWorld has been involved in this project from its inception and was a major reason for OES being awarded the California Energy Commission grant. The blending of these two technology providers is important in assuring that this project receives both the highest level of technical expertise as well as technologies that are well-grounded in decades of anaerobic digestion experience.
