Iowa Facility

At Green Plains' ethanol plant in Shenandoah, Iowa, our advanced Grower Harvester™ bioreactors are giving the term "green energy" a whole new meaning. Waste heat, waste water and CO2 released from the ethanol plant are captured and used to grow a crop that can satisfy our nation's demand for cost-effective fuel, food and animal feed. 

Phase III of the project has recently been completed, a five acre production facility consisting of greenhouses growing algae with BioProcess Algae's patened technology.  An additional capacity expansion, Phase IV, is planned will be happening soon, so be sure to check back often for updates.
