And once this material is discarded, it can be easily degraded back to its chemical building blocks and reused in new tires and other products.
Car emissions is a high-stakes issue, as last year’s Volkswagen scandal demonstrated. Pressure to meet tightening standards led the carmaker to cheat on emissions tests. But wrongdoing aside, how are automakers going to realistically meet future, tougher emissions requirements to reduce their impact on the climate? Researchers report today that a vehicle’s cold start — at least in gasoline-powered cars — is the best target for future design changes.
