K 2007: Goodyear Develops Tire With Bioplastic

Environmental themes have been strong at the K Fairs for at least 15 years. This year new bioplastics moved front and center. One of the most interesting new products comes from Novamont, which is showing a tire in which bioplastics made from starch replace some of the carbon black and silica used in automobile tires. The new material is aid to provide better grip on roads by reducing “rolling resistance” 30 per cent, according to development partner Goodyear. The result is improved fuel efficiency. Tread wear and noise pollution are also said to be reduced with the new compound. Goodyear anticipates he tire will cost the same as traditional tires. The first user is expected to be BMW, which is also a development partner. Goodyear received a 3 million euro ($4.3 million) grant from the European Commission to develop the new tire.
