A Rhode Island-based biofuels company is expanding its operation at a southwest Iowa plant.
BioProcess Algae broke ground Wednesday on a five-acre facility at the Green Plains Energy ethanol plant in Shenandoah. BioProcess opened a demonstration plant in 2009 at GPRE’s Shenandoah campus. The facility captures the waste products used to make ethanol, and uses them to grow algae. The algae is then used in animal feed.
