The Goshen College biodiesel processor was in use from 2008 to 2014. Although it is no longer producing biodiesel, this site offers information on how biodiesel can be made on an intermediate scale.
Starting in 2008, waste vegetable oil from the fryers in Westlawn Dining Hall and snack shop was converted into biodiesel that was used by the college’s back-up electrical generator. The chemical conversion from waste vegetable oil to biodiesel was done in an extensive processor that was built and run by GC students. Each year about 150 gallons of the college’s waste vegetable oil was converted to biodiesel.
