Members of the band Guster joined officials from the City of East Lansing on the Michigan State University campus this week to announce the growing use of biodiesel in the town, according to the National Biodiesel Board. Guster was in East Lansing for a performance at MSU as part of the Campus Consciousness Tour, which raises awareness in college towns about sustainable practices like using biodiesel. Their tour bus is fueled by B20, a blend of 20 percent biodiesel and 80 percent diesel.
