City of Seattle stopping use of virgin soy biodiesel

Not sure the City realizes that the soybeans are mostly being grown as cattle feed, and the oil is a byproduct. (See next post containing more info and a sample letter to the EPA). But I am encouraged that they are looking into using waste oil based biodiesel. Maybe they could scale up the Dirty Hands Coop's bring-your-own-oil style structure. We just celebrated our 2nd anniversary of continuous operation. I think we're the most consistent producer of sustainable biodiesel in the area!

Making biodiesel with 7th graders

I had fun presenting about biodiesel to 7th graders at Hamilton Middle School in Seattle.  Kids really get the need to do something about global warming.  They love the peanut burning demo, which shows the potential of biofuels.  The kids worked in groups to make pop bottle batches of bio from a variety of waste oils.
