Verde Biofuel was started by Tim McClellan, also CEO of Western Heritage furniture. Tim has applied green ideals to his business since he founded Western Heritage Furniture in Seattle in 1991.

Being a rock star used to mean doing everything to excess, from riding around in stretch limos to trashing hotel suites. These days, though, rock’s tune has changed. Biofueled-powered buses are replacing gas-guzzling tour caravans, and backstage caterers are as likely to serve tofu cubes as shrimp cocktail. From recording and distributing albums to going on tour, musicians leave a massive carbon footprint.

Students have begun making biodiesel fuel by converting used cooking oil from the dining hall. Biodiesel saves the school a little money on gasoline, gives the students lessons in engineering and chemistry, and removes oil from the waste stream.
