Los Angeles — A successful engineering validation flight was conducted Friday by United Airlines using Rentech’s certified synthetic jet fuel, RenJet. The flight marks the first time a U.S. commercial airline has used synthetic jet fuel in flight and underscores Rentech’s leadership role in a lower carbon future with the use of domestic technology and resources to fuel the nation’s transportation needs.

In December 2009, United, along with 12 other domestic and international passenger and cargo carriers, signed a memorandum of understanding that is intended to serve as a framework for a future definitive supply agreement for approximately 250 million gallons per year of certified synthetic jet fuel from Rentech’s proposed synthetic fuels and power facility in Adams County.
