By weight, the typical passenger car consists of about 60 percent steel and iron. The steel used to make the shell of your car, including the doors, hood, trunk and quarterpanels, contains a minimum of 25 percent recycled content. Many internal steel and iron parts are made using even higher percentages of recycled steel. All steel products contain recycled steel because steel scrap is a necessary ingredient in the production of new steel. With steel, unlike other materials, scrap from cars can become new steel for cans, appliances, construction materials or even new cars. Likewise, steel scrap for new cars is collected not only from automobiles but also from steel cans, appliances and construction material.
