Biogas California case study brochure
A dairy biogas facility in California was undergoing needed upgrades and expansions.

Biogas is a gaseous fuel produced by the fermentation of organic matter, most often in the form of bovine waste. This facility plays a vital role by breaking down organic matter and sourcing energy for the community.

These processes release primarily methane, hydrogen sulfide (H2S), and carbon dioxide into the air which cause unpleasant odor and create greenhouse gas.
