In Iowa, a federal grant has helped expand a program to educate diesel technicians about biodiesel throughout the Midwest. Working in conjunction with the Iowa Biodiesel Board, the regional Clean Cities initiative makes the “Biodiesel for Diesel Technicians” program available for free at community colleges in Iowa and surrounding states. The Iowa Biodiesel Board and the National Biodiesel Board developed the training program to increase mechanics’ understanding of biodiesel. Iowa is the top biodiesel-producing state.
