The recycling of metals has the potential to cut the production of greenhouse gas emissions by 300-500 million tons.
-
Using scrap metal in lieu of virgin ore generates 97% less mining waste and uses 40% less water, according to the National Institute of Health.
-
The amount of energy saved using various recycled metals compared to virgin ore is up to:
-
92 % for aluminium
-
90 % for copper
-
56 % for steel
-
-
Recycling metal creates 36 times more jobs.
-
The recycling industry, in general, generates billion’s of dollar annually and employs millions of workers across the World.
-
Recycling one ton of aluminium saves 8 tons of bauxite ore, and recycling one ton of steel saves 2,500 pounds (1134 kg) of iron ore, a ½ ton of coal, and 120 pounds (54 kg) of limestone. By recycling one ton of steel, 40% of the water used for production is conserved, and 86% of air emissions and 76% of water pollution are reduced.
