“We were considered pioneers when we built the first digester in the state two decades ago, and we’ve partnered with Regenis from the beginning not just because of their technical expertise, but also because of their tradition of honesty and integrity. Throughout the last 20 years, we’ve viewed them as our partner as we’ve experimented with cutting edge technologies. Our ongoing efforts together have allowed us to upgrade power output by 25 percent and identify a string of new products. Since we installed the digester, it has been retooled by Regenis several times to include reducing odor, taking in commercial food waste and creating marketable byproducts such as fertilizer. We now make enough clean electricity to power 400 local homes annually, and we’re proud to share our award from the Innovation Center for U.S. Dairy with their team.”
