Ford and McDonald’s USA to turn coffee bean skin into car parts

Ford Motor Company and McDonald’s USA will soon be using coffee beans in vehicle parts such as headlamp housing.

Every year, millions of pounds of coffee chaff – the dried skin of the bean – naturally comes off during the roasting process. The companies found that chaff can be converted into a durable material to reinforce certain vehicle parts. By heating the chaff to high temperatures under low oxygen, mixing it with plastic and other additives and turning it into pellets, the material can be formed into various shapes.

The chaff composite meets the quality specifications for parts like headlamp housings and other interior and under hood components. The resulting components will be about 20 percent lighter and require up to 25 percent less energy during the molding process. Heat properties of the chaff component are significantly better than the currently used material, according to Ford. This is the first time Ford has used coffee bean skins to convert into select vehicle parts.

“McDonald’s commitment to innovation was impressive to us and matched our own forward-thinking vision and action for sustainability,” said Debbie Mielewski, Ford senior technical leader, sustainability and emerging materials research team. “This has been a priority for Ford for over 20 years, and this is an example of jump starting the closed-loop economy, where different industries work together and exchange materials that otherwise would be side or waste products.”
