Iowa Biodiesel

The Iowa biodiesel industry provides many benefits to the state, in the form of green jobs, economic activity and energy security leadership.

 

Iowa’s 10 operating biodiesel plants produced an estimated 350 million gallons in 2024, according to a study by Decision Innovation Solutions. Iowa is the top biodiesel-producing state. As a heartland state, many of the state’s plants use soybean oil – an abundant local resource – to make biodiesel, but other renewable agricultural co-products and byproducts are also used, such as beef tallow, inedible corn oil and recycled cooking grease.
