SEATTLE – The city of Seattle has temporarily stopped buying soy-based biodiesel for its vehicles over concerns it is more harmful to the environment than regular diesel.
City fleets and facilities director Brenda Bauer said the city is looking into biofuels that aren’t made from food crops and is testing biodiesel made from waste grease.
Critics say crop-based biofuels, such as ethanol made from corn and biodiesel from soy, harm the environment because of the land needed to grow crops and greenhouse gas emissions involved.
Seattlepi.com reports the city had been buying about 73,000 gallons of biodiesel a month for hundreds of its diesel vehicles, such as fire engines and pickups.
