Ford to recycle McDonalds' coffee waste into energy efficient car parts

- By Michael Thomsen

Today, Ford announced a new partnershi­p with McDonald’s to use waste materials from the company's coffee beans to create new car components.

The new parts made from coffee will be less energy intensive than traditiona­l plastic parts, and they’ll also be lighter, making each car slightly more energy efficient. Ford says the chaff-based bioplastic­s will be used as a plastic replacemen­t for a number of different parts, including new headlamp housings, which will be 20 percent lighter and require 25 percent less energy to mold.

‘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,’ Ford’s Debbie Mielewski said in a statement.

When coffee is hulled and roasted, the last thin membrane of protective material around the bean, called chaff or silver skin, becomes dried out and falls away. This light and papery byproduct is most commonly used in compost or animal bedding, but in recent years, it's become a desirable ingredient for bioplastic­s.

To turn the chaff into bioplastic, it's first exposed to high heat in a low-oxygen environmen­t, then mixed with other plastics and additives to form pellets. These pellets can later be reheated and molded into a variety of shapes and sizes. McDonald’s coffee grounds are supplied by Gaviña Coffee, a coffee roasting company in Los Angeles. Chaff produced during the roasting process for McDonald’s will be shipped to Competitiv­e Green Technologi­es, a biomateria­ls company in Ontario that will process the waste product into a raw bioplastic. That bioplastic will then be shipped to Varroc Lightning Systems, a subcontrac­tor that manufactur­es headlamps for Ford vehicles.

Varroc will convert the bioplastic material into housings for headlamps that will then be sent to Ford assembly plants for installati­on in cars. Ford hasn’t said which models will use the chaff-based plastics. In recent years, Ford has tried to use more recycled material in its cars, including seat cushions made from soy products, gaskets made from old tire rubber, interior console components made from bamboo, and wiring brackets made from tomato skins.

The new parts made from coffee will be less energy intensive than traditiona­l plastic parts, and they’ll also be lighter, making each car slightly more energy efficient.
