Domestic biodiesel production hits record in May

U.S. biodiesel production hit a record level of 111 million gallons in May, according to data released Wednesday by the U.S. Energy Information Administration.

The biodiesel was produced at  116 active plants with a total capacity of 2.2 billion gallons per year.

Production for the first five months of 2013 was 449 million gallons, an increase of 17 million gallons from the same period in 2012. More half of the feedstock used to produce the biodiesel in that period was  soybean oil.

Ethanol: Biodiesel can solve the ethanol debate, supporters say

Most biodiesel fuel is blended with diesel fuel made from petroleum and is used for transportation, the agency said.

Biodiesel still represents a tiny portion of the fuels market. The agency reported it accounted for less than 2% of U.S. distillate fuel oil product supplied of 3.9 million barrels per day during the first five months of 2013.
