Green Plains Renewable Energy and BioProcess Algae to Host Agriculture Secretary Vilsack at Grand Opening of Phase II Grower Harvester Bioreactors

Green Plains Renewable Energy, Inc. (GPRE) announced today that U.S. Agriculture Secretary Tom Vilsack will deliver the keynote address at the Grand Opening of Phase II of BioProcess Algae's Grower Harvester^TM bioreactors in Shenandoah, Iowa.

"We are honored to have Secretary Vilsack deliver the keynote address at this important event for BioProcess Algae and to see firsthand our bioreactor technology growing and harvesting algae," said Todd Becker, President and Chief Executive Officer of Green Plains Renewable Energy. "The next step for us is to take our commercial scale reactors and build out an algae farm at our ethanol plant in Shenandoah, which can produce inputs needed for feed, food and next generation algae-based fuels. The co-location at an ethanol plant has proven to be the right platform to rapidly commercialize this technology."

The grand opening will take place at 4:30 pm central daylight time on Friday April 15, 2011 at Green Plains' ethanol plant located at 4124 Airport Road, Shenandoah, Iowa.
