A new report released by the Iowa  Department of Revenue shows biodiesel blends represented 70% of the total reported sales of on-road diesel last year in the state — with blends of 11% to 20% biodiesel (B11-B20) making up most of those sales. 

“There’s no question that Iowa’s comprehensive state policies encouraging pro­­duction and use of biodiesel have helped Iowa become the number one biodiesel-producing state,” said Grant Kimberley, Iowa Biodiesel Board executive director. “We produced 345 million gallons last year.”

According to­ the 2019 Retailers Fuel Gallons Annual Report, Iowa fuel retailers reported selling 636.9 million gallons of taxable diesel fuel.
