The Pitt County Schools recently put the "Biodiesel 4 Schools" program into action.
Local restaurants can either donate or sell their used cooking oil to the schools.
That waste oil can then be converted into biodiesel that will eventually power most Pitt County School buses.
There are about 175 participating restaurants in Pitt County.
Kentucky Fried Chicken is one of the latest to get onboard.
As a thank you, KFC received a rebate for $1,000, in which they decided to donate all of that money to northwest elementary school.
