We partner with the farmer and plan for the long-run

CalBio digesters are built to last. We are able to provide full financing of a project or the dairy can provide the capital. Both approaches generate a new revenue stream for the dairy. In addition, we design dairy-specific digesters to augment waste handling operations, save costs, and assist in the nutrient management process. CalBio operates the project, enabling the dairy to remain focused on its business.

Our Strategic Partners


We are pleased to announce our partnership with 4Creeks and 4C Global. Independently and together we have designed the new generation of dairy digesters.

CalBio Projects

CalBio and 4Creeks have combined to design and construct the most modern and powerful digesters in California. With 10 projects either completed or under construction, our project knowledge helps lead the industry.
