Tyson Foods and Syntroleum Corp. have approved plans to build and fund Dynamic Fuels' first renewable synthetic fuels facility in Geismar, La., clearing the way for construction to begin.

Dynamic Fuels is a 50-50 joint venture between Tyson and Syntroleum to convert low grade, inedible fats and greases into renewable transportation fuels for the military and civilian markets.

In conjunction with plant approval, Tyson and Syntroleum approved the project budget of $138 million. Construction is expected to begin in October, and mechanical completion of the plant is expected by the end of 2009.

Once in operation, the Geismar plant is expected to produce about 75 million gallons of renewable synthetic fuel annually.
