The large-scale field trial of the Methane Eradication Photochemical System represents the first real-world validation of a scalable technology capable of eradicating methane emissions from livestock barn air. The prototype MEPS unit, housed in a standard 40-foot shipping container, processed air samples from a 250-cow, open-sided dairy barn on a dairy farm in Denmark.

INSIGHTS: This promising technology from Ambient Carbon will generate considerable interest from dairy operations in the U.S.. Danone North America provided financial support for the trial.
