American By-Products Recycling LLC and Duke Farms co-hosted a dozen Dartmouth College students and their Big Green Bus on a 12,000 mile trip around the U.S. to promote environmental awareness. American By-Products' facility in Hillsborough (Planet Earth Biodiesel at 301 Roycefield Road) filled the bus with B-100 biodiesel (100% biodiesel) which will probably be able to fuel the bus to New Orleans.  Last year, Plant Earth filled the bus with recycled vegetable oil.
