American students produce biodiesel from used kitchen oil

Several students from U.S. campuses have taken initiative and have produced their own biodiesel, even at times of chemistry. Interesting is the "raw material" used to obtain it, namely the oil used in frying potatoes in student cafeterias. Students came up with this idea for environmental reasons but economic, fuel costs are lower when using biodiesel.
In general, campuses have large areas of green spaces, and these must be maintained with special vehicles. These vehicles need fuel with biofuel initiative to supply their product to students.
For example, the University of New York represents about 8% of biodiesel fuel used on campus, and Dickinson College in Carlisle, Pennsylvania, produces between 185 and 550 liters of biodiesel per week.
Even if the numbers are insignificant seem a small step in the right direction and show us what can be achieved with little effort and imagination.
