According to the Des Moines Register, Iowa is getting two more ethanol plants – one in Superior and one in Buffalo. Green Plains Renewable Energy plans to build a 50 million-gallon-a-year plant near Superior that will be similar to a plant Green Plains is building in Shenandoah. The Superior plant will open in spring 2007.
