Tri-State said that the biodiesel fuel, which is made primarily from waste cooking oil collected from New York City restaurants, will be phased in to FreshDirect’s fuel supply over the course of the next two months.

By February 2008, FreshDirect’s entire fleet will be biodiesel powered, making it the largest private trucking fleet in the city to use the fuel. Tri-State estimates that FreshDirect’s switch to biodiesel will result in a yearly reduction of approximately 7.5 million pounds of CO2.

The biodiesel firm also claims that the switch will result in reduced levels of other harmful emissions such as carbon monoxide, sulfur, unburned hydrocarbons and particulate matter.

Brent Baker, founder of TriState Biodiesel, said: I congratulate FreshDirect’s leadership in helping New York City clean up its air and become more energy independent, and hope other fleets in the city will step up and do the right thing as well.
