North Carolina Swine Waste-to-Energy Project Wins ACEC National Honors Award for Engineering Excellence


On Tuesday, April 23, 2013, the Loyd Ray Farms Swine Waste-to-Energy Project received an Honors Award at the ACEC Engineering Excellence Awards Gala at the Grand Hyatt in Washington, D.C.  This project, designed by the Winston-Salem based Engineering firm, Cavanaugh & Associates, P.A. was recognized as one of the top 24 Engineering achievements in the United States.   The American Council of Engineering Companies annually pays tribute to exemplary Member Firm achievements from around the globe, and honor the year’s most outstanding Engineering accomplishments at this event.  Cavanaugh & Associates, P.A., received the award for their role in conception, design, and operation of the project.  Projects from all over the world were nominated for recognition, and were evaluated on the basis of uniqueness, innovative applications and future value to the engineering profession, as well as the public, social, economic and sustainability benefits created.  An expert panel of judges selected 24 top award winners from the 171 nominations – 16 Honor Awards, and 8 Grand awards, from which one Grand Conceptor Award winner is chosen.  The Engineering Excellence Gala celebrates with pride and elegance the most outstanding project achievements of the engineering profession.

Steve Cavanaugh, Marvin Cavanaugh, Gus Simmons and Tory Wagoner, all officers of Cavanaugh & Associates, P.A., were present to receive the award.  Cavanaugh, which specializes in Stewardship through Innovation, collaborated on this project with Duke Energy, Duke University, and internet giant Google.  The team leads the state with its first-of-its-kind Waste-to-Energy system, and the project is the first pig farm in North Carolina to generate Renewable Energy Credits (RECs) from its waste.  The project also reduces greenhouse gas emissions equivalent to removing 900 cars from the roads, annually.  Funding support was provided by the NC Division of Soil and Water Conservation and the USDA Natural Resource Conservation Service. This pilot project, which generates electricity from pig waste exemplifies the importance of generating environmental renewable energy, and its future significance in reducing emissions and reducing the carbon footprint of farms.  The highly-acclaimed Loyd Ray Farms project previously received the2013 ACEC Henry A. Stikes Grand Conceptor Engineering Excellence Award for the State of North Carolina.
