Cars interiors of the future could be built with coffee and eggshells to be more eco-friendly, says study
New ‘design study’ has looked at how car interiors could be more sustainable.

Coffee, eggshells and rice could be used as materials for car interiors of the future, a new study has discovered.
Design and engineering consultancy Callum has identified a variety of ‘viable materials’ that could be used in a car’s cabin to make it more sustainable. Having consulted with green-tech company Ottan, Callum was able to find materials which could replace plastics but still keep up with the requirements of a fully-functioning car.
Eggshells were mixed with resin to create a smooth material for areas such as the window switch surrounds, while the ‘green’ credentials of this feature were boosted by mixing it with walnut shells, increasing its recycled content to 84 per cent from 78 per cent.
