Biodiesel is a clean-burning, biodegradable, alternative fuel produced from vegetable oils or animal fats. To be called biodiesel, it must meet American Society for Testing & Materials (ASTM D6751) quality specifications. Biodiesel blends can range from 1% to 99%, however common blends used in Iowa are B5, B11 and B20 (5%, 11% and 20% biodiesel, respectively), although many farmers use even higher blend levels in their on-farm equipment.
Using biodiesel is not only cleaner for our air, it’s cleaner for your engine. Biodiesel provides increased cetane and superior lubricity, helping to extend engine life and reduce maintenance costs. Biodiesel blends up to B20 can be used in existing diesel engines with little to no impact on engine performance, while exhibiting cold flow properties similar to #2 diesel.
What’s more, biodiesel is produced in nearly every state in the nation, spurring economic development and supporting good paying, American jobs. The U.S. has more than 125 biodiesel production facilities and 3 billion gallons of annual production capacity. Iowa lead the nation in 2020 with 351 million gallons of production, or about 20% of total U.S. production.
