Marco Arezio - Consulente materie plastiche - Cars parts products with a compound containing coffee waste

Ford and McDonald’s have created a collaboration inspired by the circular economy

The two companies active in the mobility and catering sector have involved Competitive Green Technology to create a compound that could use some coffee waste, combined with polypropylene, to produce spare parts for cars.

The aim was to study a recipe that would make some parts of the car lighter and more robust than traditional recipes.

The waste, to prevent it from burning, is treated in an environment with a low oxygen content and then mixed with polypropylene to form granules , which will be lighter than traditional polypropylene and will need less energy for molding .

According to the technical leader of Ford’s new materials research team, Mr. Mielewski , the waste from coffee roasting is used to replace the talc which normally composes polypropylene compounds, bringing about a weight reduction of around 20% and a good resistance to high temperatures.

The first applications were made in the production of headlight housings , following tests in which greater resistance to temperatures was noted compared to the piece made with the new traditional compound.

In fact, the housing of the headlights is an area where much heat is created and the technical properties of the new material seemed immediately apt for this work.

These new areas for headlights will be built by the supplier Varroc Lighting Systems and will be positioned on the Lincon Continental sedan following the new changes planned in 2020.

According to the Ford team, the headlight housing is just the beginning of the production of car parts made with this Green recipe and others under study, as happened with the soy foam used in Mustang seats and that today are found in many other machines of the company.

The research and development of recipes that are compatible with the circularity of the components used, are intended to use the pieces produced in some cars of the Ford and Lincon range, with particular attention to those elements where, inside the car, they are develop high temperatures .

We are talking about battery casings , under hoods and engine covers .

Obviously the fragrance of the coffee, on the components to be installed, is removed in the production phase of the compound to prevent your machine from having the smell of a cup of freshly poured coffee.
