Member press release – American Biogas Council Board re-elects officers, Sheff to serve fifth term

April 7, 2023 – WASHINGTON – Today, the American Biogas Council (ABC) Board of Directors announced the re-election of its officers, including incumbent Chair Bernard Sheff, PE from Montrose Environmental Group, who was elected to a fifth term. In addition to Sheff, Bryan Sievers of Sievers Family Farms/Roeslein Alternative Energy and Randy Beck of WM, Inc. were re-elected as co-Vice Chairs; Melissa VanOrnum of DVO was re-elected to Treasurer; Dr. Craig Frear of Regenis was re-elected as Secretary, and Patrick Serfass was re-elected as Executive Director. The 2023 Board will have 27 Directors, including newly-elected Director Ivor Castelino, Managing Director of Corporate Development at Bloom Energy.

In a career that has been marked by many chances to learn, the involvement with the American Biogas Council has been one of my greatest opportunities,” said Sheff. “The staff at ABC and our Executive Director Patrick Serfass have made it all possible and the support of our board is the reason I have this extended tenure. It is a sincere honor and blessing to continue on as the Chairman of the Board of the American Biogas Council.

At present, the US biogas industry has 2,300 operating projects in all 50 states. Biogas systems recycle organic material into renewable energy and soil products. Each year the U.S. generates millions of tons of manure, agricultural waste and food scraps, plus trillions of gallons of wastewater. The potential to build new biogas systems to manage those large volumes of organic waste is enormous. At least 15,000 new systems could be built, catalyzing an estimated $45 billion in new capital deployment along with 374,000 short-term construction jobs to build the new systems and 25,000 permanent jobs to operate them. This number of systems could produce enough energy to power 7.5 million American homes and reduce emissions equivalent to removing up to 15.4 million passenger vehicles from the road, in addition to many other benefits.
