Mansfield Energy Corp, a leading North American energy supply and logistics provider, announced Yara International ASA, Mansfield's strategic supplier of DEF (diesel exhaust fluid), has opened the world's largest DEF plant in Brunsbüttel, Germany. DEF is a fluid used to remove harmful NOx emissions from diesel engines and Yara is the global leading producer of DEF.

"With annual DEF demand forecasted to top 1.7 billion gallons by 2026, our ongoing partnership with Yara enables us to offer customers Air1, the highest quality DEF on the market," explains Andy Austin, SVP of Specialty Products for Mansfield Energy. "The completion of this expansive plant demonstrates Yara's ongoing commitment to meet our customers' growing demand across North America."

In 2010, the EPA passed the Clean Air Act which made heavy duty diesel engines comply with stringent emission regulations to reduce NOx emissions. The most efficient way to meet these regulations is to use SCR technology which requires DEF as the operating fluid. Boosting the demand for DEF, virtually all new diesel engines including semi-trucks, off road machinery, boats and an increasing number of diesel passenger cars, will use SCR technology.
