Top state officials will keynote the Iowa Renewable Fuels Association Summit on Wednesday in Des Moines.

The event will feature the latest news in Iowa’s biodiesel and ethanol industries with a keynote address by Iowa Governor Chet Culver and a special address by Iowa Secretary of Agriculture Bill Northey.

Iowa is the leader in renewable fuels production with 26 ethanol refineries and the capacity to produce over 1.7 billion gallons annually. There are another 21 ethanol refineries under construction or expansion that will add 1.6 billion gallons of annual capacity. In addition, Iowa has 14 biodiesel refineries with a combined annual capacity of over 315 million gallons either in operation or under construction.

The Iowa Renewable Fuels Association was formed in 2002 to represent the state’s ethanol and biodiesel producers.
