TURN YOUR WASTE
INTO ENERGY
CalBio captures methane at a dairy farm and turns it into fuel and power.
We partner with dairy farmers and invest in long-term solutions.
Since 2006, CalBio has designed, developed, operated, and financed digester projects. We use our expertise to turn dairy waste into carbon-negative energy, building successful projects and delivering long-term value for both farmers and external partners.
Mastering Key Project Components
With almost 20 years of experience, we have industry-leading expertise to handle every stage of the development process – financing, engineering, construction, operations, and credit generation.
Biogas Production
We transform dairy waste into ultra-clean renewable natural gas (RNG), vehicle fuel, and electricity.
Maximizing Grant & Credit Value
We work closely with federal and state agencies, utilizing available programs to make a project economically secure.
Tailored Solutions for Dairy Farmers
Every family operation is unique, and we design systems to fit their specific needs based on our many years of experience. Our solutions streamline operations, save time and money, and position dairy farm partners for long-term success.
1
Waste Collection
Manure is flushed into collection areas, where solids are separated before entering the digester—integrating seamlessly into daily dairy operations.
2
Biogas Capture
Inside the digester, microorganisms break down organic matter, producing methane-rich biogas. Instead of escaping into the atmosphere, it's captured for energy production.
3
Renewable Natural Gas
Captured methane is converted into Renewable Natural Gas (RNG) to power trucks, buses, and other vehicles or to generate electricity. RNG revenues come from California's Low Carbon Fuel Standard (LCFS) credits, U.S. EPA Renewable Identification Numbers (RINs), and methane sales. The electricity can be sold to a utility, used to power the dairy farm, or used to power data centers.
4
Effluent Use
Digested effluent water is recycled as flush water, keeping lanes cleaner, improving hygiene, and reducing slips. The process also converts over 60% of organic nitrogen into a more plant-available form, enhancing crop yields and lowering fertilizer costs.
Dairy Biogas,
High-impact Uses
Fueling Transportation
Biogas is upgraded to RNG and powers trucks and buses with a negative-carbon, locally sourced alternative to diesel.
Grid-Ready Electricity
Biogas is used to generate electricity that can be sold or used onsite. The biogas can be stored up to four days ensuring reliable power when needed.
Reliable,
On-Demand Energy
Dairy farm biogas provides consistent, flexible energy, delivering steady power when needed.
Endless Possibilities
CalBio continues to explore new end-use opportunities for our biogas, including potential applications in maritime fuel, sustainable aviation fuel, power for data centers, and more.
