Biodiesels for Municipalities

The environmental bandwagon is not always as green as it seems…

The city of Seattle has temporarily stopped buying biodiesel fuel for its fleet of vehicles because of concerns that the soy-based mix it was using was more harmful to the environment than regular diesel.

But Brenda Bauer, director of Seattle’s Fleets and Facilities Department, said the city could start using a different type of biodiesel made from waste grease — byproducts of food production.

“Not all biodiesels are the same,” Bauer said.

Fossil fuels may be bad, but some biodiesels may have just as negative an impact as conventional oil – although I find it hard to believe that anything is as bad as oil extracted from the tar sands.
