Goodyear anounces new "green filling" for tires - it's made from cornstarch

Sustainable and renewable materials - such as cornstarch - are going to be sources for Goodyear's new greener tires. Goodyear announced that it's developing a new line of low rolling resistance tires which will not only save some fuel, but are more "respectful for the environment," since they require less CO₂ to be produced than standard Goodyear tires. Cornstarch is going to be added as "biologic" filling as a substitute for silicon and soot, both of which are usually obtained from oil. Goodyear has teamed up with Novamont, an Italian R+D company, BMW and obtained funds from the European Life Program to develop the tires.
