One for the road: Ford and McDonald’s to turn coffee waste into car parts
Waste coffee from McDonald’s is to be turned into new, lightweight car parts under a new partnership announced between the fast food giant and the carmaker Ford. Researchers from the two companies found that coffee chaff — the dried skin on the bean that naturally comes off during the roasting process — can be converted into a durable material to reinforce vehicle parts, such as headlamp housing. 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 innovation will help make Ford car parts about 20 percent lighter and provide up to 25 percent energy savings during the molding of parts. The heat properties of the chaff components are significantly better than the material currently used, Ford said.
