LOS ANGELES--(EON: Enhanced Online News)--Rentech, Inc. (NYSE AMEX: RTK) today announced it is sponsoring Get Green Racing, the first green mission NASCAR team. By sponsoring NASCAR’s first green mission racing team, Rentech can reach NASCAR’s broad audience of over 75 million fans to encourage positive environmental change on a large scale.

“Rentech is excited to be a part of the first green mission NASCAR team to encourage consumers and businesses to be more environmentally aware in their choices”

Rentech is a nationally recognized leader in the development of clean energy technologies. The Company strives to deliver solutions to customers and licensees to effectively address national energy security issues, rising long-term demand for fuels and electric power and limited domestic petroleum refining capacity while lowering emissions profiles.

“Rentech is excited to be a part of the first green mission NASCAR team to encourage consumers and businesses to be more environmentally aware in their choices,” stated Rick Penning, Executive Vice President of Technology and Commercial Affairs. “It is an opportunity to reach a broad audience to support the need for developing renewable synthetic fuels that decrease our dependence on foreign supply and are more environmentally friendly.”

“Developing synthetic fuels that have a near zero carbon footprint, are made from waste materials and can be used in existing engines without modifications is a great step forward and Get Green Racing is excited to have a partner like Rentech who is a leader in this field,” said Frank Cicci, Get Green Racing owner.

As part of its sponsorship with Get Green Racing, hauling vehicles for select NASCAR Get Green Racing events will use Rentech’s synthetic RenDiesel^®. RenDiesel^® meets ASTM D-975 fuel specifications, can be used as a neat fuel and burns cleaner than traditional diesel fuel.

Rentech is developing the country’s first renewable synthetic fuels and base-load renewable power facility from green waste in Rialto, California. Rentech has contracted to supply renewable RenDiesel® from this facility to eight airlines for ground service equipment operations at Los Angeles International Airport when the facility is expected to be operational in late 2012. These airlines include Alaska Airlines, American Airlines, Continental Airlines, Delta Air Lines, Southwest Airlines, United Airlines, UPS Airlines and US Airways.
