A new report shows the amount of biodiesel blended into diesel fuel in Iowa has more than tripled over the last two years.
The report released Monday by the Iowa Department of Revenue says biodiesel made from vegetable oil or animal fat is now blended in more than 42 percent of all diesel fuel sold in the state. The report shows 23.3 million gallons of biodiesel was mixed with diesel fuel last year, up from 7.4 million gallons in 2010.
Ethanol, which is made mostly from corn and mixed with gasoline, was in about 81.7 percent of all gasoline sold in Iowa, down slightly from 82.5 percent in 2010.
Iowa has 12 biodiesel plants and 41 ethanol refineries, more than any other state.
