Porsche has developed new recycling techniques for end-of-life cars. It teamed up with chemical giant BASF and a sustainable tech company. Porsche claimed a few years ago that 70 percent of the 911s produced going back to the 1960s were still on the road. For the pilot study, Porsche used BASF’s polyurethane to make the foam for a batch of three-spoke sports steering wheels. The foam isn’t 100 percent made from recycled material, there’s still some conventional, dirty fossil fuel plastics in there.
