NORFOLK, Va. – Dynamic Fuels, a 50/50 venture owned by Tyson Foods Inc., has signed an agreement with Mansfield Oil Company to supply renewable diesel to Norfolk Southern Corp, Tyson announced Feb. 14. Norfolk has been using a 100-percent pure Dynamic Fuels renewable diesel at its Meridian, Miss., rail yard since early January, according to Tyson.

Dynamic Fuels and Syntroleum Corporation recently signed commercial off-take and strategic alliance agreements with Mansfield to market renewable diesel to fleet customers. Dynamic Fuels produces renewable and synthetic fuels from animal fats and greases. The company's Geismar, La., plant produces renewable diesel as "drop in" fuel that can replace 100 percent of petroleum diesel in a diesel engine without engine modification.
