Over 400 million tons of metal is recycled each year. In the United States alone, an estimated 65 million tons of steel was recycled in steel mills and foundries in 2008. Recycling conserves precious natural resources, and the benefits to the environment in saved energy and reduced greenhouse gas emissions are also well recognized
Nonferrous metals, including aluminum, copper, lead, nickel, tin, zinc and others, are among the few materials that do not degrade or lose their chemical or physical properties in the recycling process. As a result, nonferrous metals have the capacity to be recycled an infinite number of times.
Nonferrous scrap is then consumed by secondary smelters, refiners, ingot makers, foundries and other industrial consumers in the U.S. and in more than 90 countries worldwide. These consumers rely on nonferrous scrap as a competitive, environmentally friendly and energy-efficient input to make brand new products, continuing the nonferrous metal life cycle. The BIR estimates that almost 40% of the world’s demand for copper is met using recycled material, while more than 80% of the zinc available for recycling is eventually recycled.
