The Benefits of Metal Recycling: Why Recycle Metal?
The United States recycles 150 million metric tons of scrap materials annually, including 85 million tons of iron and steel, 5.5 million tons of aluminum, 1.8 million tons of copper, 2 million tons of stainless steel, 1.2 million tons of lead and 420,000 tons of zinc, according to the Institute of Scrap Recycling Industries (ISRI). Other metals such as brass, bronze, magnesium and tin are recycled as well.
The amount of energy saved using various recycled metals compared to virgin ore is up to:
-- 92 percent for aluminum
-- 90 percent for copper
-- 56 percent for steel
Metal recycling also conserves natural resources. Recycling one ton of steel conserves 2,500 pounds of iron ore, 1,400 pounds of coal and 120 pounds of limestone. Recyling a ton of aluminum conserves up to 8 tons of bauxite ore and 14 megawatt hours of electricity.
Moreover Recycling scrap metal reduces greenhouse gas emissions and uses less energy than making metal from virgin ore.
