Iowa biodiesel production is expected to account for roughly 20 percent of total U.S. biodiesel production in 2020.
Soybean oil continued to be the feedstock of choice for the majority of Iowa biodiesel production, making up over 85 percent. Corn oil was second at just over eight percent. Animal fat, canola oil, and used cooking oil made up the rest of the feedstock used by Iowa biodiesel producers.
