Steel is the most recycled material both in the United States and worldwide. In the United States alone, 74 million metric tons of ferrous scrap was processed by the scrap recycling industry last year – more than 55 percent of the volume of all domestically processed material.
Obsolete ferrous scrap is recovered from automobiles, steel structures, household appliances, railroad tracks, ships, farm equipment, and other sources. In addition, scrap generated from industrial and manufacturing sources accounts for approximately half of the ferrous scrap supply.
Nonferrous metals, including aluminum, copper, lead, nickel, 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.
More than eight million metric tons of nonferrous scrap were processed in the United States last year from a wide array of consumer, commercial, and industrial sources: everything from copper and precious metal circuitry in electronic devices to soft drink containers, automobile batteries and radiators, aluminum siding, airplane parts, and more.
