California Bioenergy develops, owns, and operates projects that capture and destroy methane produced from dairy cow waste, creating greenhouse gas emissions reductions and renewable electricity in the process. CalBio's process consists of four main steps: Waste Collection, Greenhouse Gas Capture, Carbon Offset Creation, and Green Energy Production. These activities are seemlessly intergrated into a dairy's current operations, providing minimum disruption and maximum value to the dairy while also benefiting the environment.
1. Waste Collection:
Waste collection is integrated smoothly with a dairy’s existing operations. Manure is flushed into collection areas and then flows to a biogas control system, the main component of which is an anaerobic digester, with solids separation before or after the digester, depending on the technology utilized at a given dairy.
2. Greenhouse Gas Capture:
In an anaerobic digester, microorganisms break down waste and create biogas, which is then trapped in the digester. The captured biogas primarily consists of methane, a potent greenhouse gas that otherwise would have been released to the atmosphere.
3. Carbon Offset Creation:
The biogas is then destroyed, primarily by combusting it to generate electricity (see below). This destruction of greenhouse gases creates emissions reductions, or carbon offsets. CalBio creates carbon offsets according to the Climate Action Reserve's Livestock Project Protocol. The offsets are verified by independent, third-party verifiers ensuring that they meet high environmental integrity requirements. For more information on carbon offsets and how our projects create them, please go to our Carbon Offsets page.
4. Green Energy Production:
The biogas collected in our systems is used to produce green electricity. Our projects export this electricity to the local grid, providing a valuable source of wholesale distributed generation capacity.
