DTE Energy said Friday that it will reduce the environmental footprint of its 800 diesel-fueled trucks and service vehicles by converting the fleet to cleaner-burning biodiesel fuel. 

Biodiesel is an alternative fuel produced from domestic renewable resources such as vegetable oil and animal fat. Compared to conventional diesel fuel, the use of biodiesel significantly reduces emissions of carbon dioxide, carbon monoxide and other air pollutants.

Converting DTE Energy's 800 diesel-fueled vehicles to biodiesel is the environmental equivalent of taking about 120 of those vehicles out of service.

DTE will demonstrate the conversion Tuesday at 10 a.m. at its Redford Service Center, 12000 Dixie in Redford Township.

DTE's biodiesel fuel is being supplied by Romulus-based RKA Petroleum.
