McDonald’s has teamed up with Ford to develop a sustainability-focused initiative turning used coffee beans into a car part.

The Lincoln Continental in 2020 will feature headlamps consisting of a part that is made from converted chaff.

“This is just the starting point for us,” said Ian Olson, senior director of global sustainability at McDonald’s. “That’s why we are excited about it.”

The chaff being used is coming from McDonald’s North American coffee supplier, Mother Parkers Tea & Coffee Inc. in Canada.

The chaff used in the car is replacing a dense material used for the back end of the headlamp. It is said that the new product created by the chaff is 20 percent lighter, and higher heat performance, leading to a more fuel-efficient car.
