Rentech’s Synthetic Jet Fuel Certified for Commercial Aviation

LOS ANGELES--(BUSINESS WIRE)--Rentech, Inc. (NYSE AMEX: RTK) announced today that ASTM International’s full governance committee has unanimously approved modifying the specifications for commercial aviation jet fuel to include up to a 50/50 blend of synthetic Fischer-Tropsch jet fuel. The jet fuel certified by the Federal Aviation Administration (FAA) for use in commercial aircraft relies on ASTM’s specifications. Rentech’s jet fuel, RenJet^®, qualifies under the approved specifications of synthetic jet fuel.

With the ASTM specifications, fuel derived using the Fischer-Tropsch process, including RenJet^® produced from renewable or fossil feedstocks, is the first and currently only alternative jet fuel certified for use by the FAA. Rentech currently produces jet fuel at its Product Demonstration Unit that, when blended with petroleum-derived fuel, meets the ASTM International specifications. RenJet^® is biodegradable, clean burning and virtually free of particulates, sulfur and aromatics.

D. Hunt Ramsbottom, President and Chief Executive Officer of Rentech, stated, “ASTM’s approval of synthetic jet fuel for use in commercial aviation marks the achievement of a significant milestone for Rentech, the commercial aviation industry and the country.” Mr. Ramsbottom continued, “Rentech is one of the few companies that has the technology to produce and supply these fuels to the commercial aviation market and the U.S. Air Force, which has already certified the use of synthetic fuels in most of its aircraft.”
