Sysco Corp., the largest foodservice marketing and distribution organization in North America and the owner of the largest private truck fleet in the United States, recently finished testing and is using biodiesel blends supplied by TransMontaigne Inc. in its truck fleets in two states. The company evaluated blends of between two and five percent for its fleets in Florida (Miami and Fort Lauderdale) and in Minnesota (Minneapolis).  Approximately 300 tractor trailers are successfully running on the biodiesel blends, with plans for expansion in the future.
