California Bioenergy (CalBio) is one of the nation’s leading developers, owners, and operators of anaerobic dairy digesters.  Founded in 2006, it began as a vision between a few committed innovators and dairy families and has since grown into the largest producer and marketer of renewable natural gas (RNG) from dairy waste in the United States.  

CalBio was built in partnership with local dairy farmers who continue to serve as long-standing partners, collaborators, and project hosts.  CalBio’s projects create critical new revenue streams for local dairy families, reduce on-farm methane emissions, and bring local environmental and economic benefits.  For nearly two decades, CalBio and its local dairy partners have proven that America’s clean-energy future can be rooted in rural communities.

CalBio dreams of a decarbonized world and continues to advance that vision through every project.  In California alone, 78 of its operational projects produce over 4 million British thermal units (MMBtu) of RNG and renewable electricity annually and reduce more than 1.9 million metric tons of carbon dioxide equivalent (CO₂e) each year.  That is equivalent to removing approximately 430,000 gasoline cars from the road each year.  Together, these accomplishments move us from dreaming of a decarbonized world to actively building one.

CalBio operates from two primary hubs, with corporate services out of Dallas, Texas, and major operations out of Tulare, California.  Its teams manage the full lifecycle of each digester project, from initial conception, through design and construction, to continued operations, maintenance, and reporting.  CalBio’s portfolio includes single-site digesters as well as multi-site clusters.  CalBio is also exploring opportunities to expand its successful dairy RNG model beyond California to support additional communities throughout the United States.

In partnership with SoCalGas, CalBio is injecting RNG into the SoCalGas pipeline at six interconnection sites located in Kern, Tulare, Kings, and Madera counties.  By working closely with SoCalGas, CalBio is turning dairy-based RNG into a statewide climate solution and advancing their shared commitment to a cleaner, more sustainable California.
