The production and use of polymers has been growing and that trend is expected to continue. Likewise, the production of metals from ores is on the rise because of increasing demand. Recycling polymers and residual metals can result in significant energy savings and environmental benefits including a reduction in CO2 emissions. Metals constitute more than 75 % of a vehicle's weight and polymers constitute another 7 %. Eventually, goods made with polymers and metals reach the end of their useful lives. Each year more than 50 million vehicles reach the end of their service life worldwide, 15 million of them in the United States. More than 95 % of the vehicles enter a recycling infrastructure that includes auto parts dismantlers, remanufacturers, and scrap recyclers (shredders). Today, more than 75 % of automotive materials are profitably recycled via parts re-use, parts and components re-manufacturing and, ultimately by the scrap processing industry. This article describes recycling options for the polymers and metals in end-of-life vehicles.
