“Regenis had already built our digester and kept it running continuously for six years so we had confidence hiring them to build our fine solid separation system. Now we’re able to remove phosphorous and nitrogen from our liquid waste stream, apply nutrients to our crops more precisely and reduce the amount of liquid we have to haul off the

“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.
