Make Your Financing Easier

Financial institutions need to know your business model is solid and that your digester will deliver the amount of biogas you claim in your spreadsheets before they underwrite your project. That’s why as a third-party developer, it’s essential to have an experienced operator.

Our partners have received multiple industry awards for the continuous operation of digesters Regenis built and operated.

Get The Most From Your Methane Capture

Getting the manure mix right is key to creating the maximum amount of biogas. Getting it wrong will shut your digester down for extended periods. We’ve been perfecting that mix on dairies since 2004, and our operations team closely monitors what goes in and what comes out daily.

“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 farm.”

“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.

“Craig Frear and the team at Regenis have supported the American Biogas Council for more than a decade with their deep knowledge and technical expertise on the design and operation of anaerobic digesters. As a result, we are providing a better service to the biogas industry and countless developers, operators, and digester owners are producing more biogas than they would have without Regenis.”
