Practiced since ancient times, scrap metal recycling embodies the spirit of sustainable development. That is, "development, which meets the requirements of the present without compromising the ability of future generations to fulfill their own needs," as defined by the World Commission on Environment and Development. Recycling widens the efficient use of metals and minerals, reduces pressures on landfills and incinerators, which results in significant major energy savings compared to primary production.
The recycling of scrap metals has been in practice since ancient times and today it has become a multi-billion dollar business across the world. The recycling companies collect the metal scrap from individuals, machine shops, manufacturers, government entities, and other industries. Scrap metal is composed of several items that include, - aluminum cans, used pipe, automobiles, appliances, sheet metal buildings, pots, computer components, pans, bicycles, lawn furniture, copper wire, obsolete equipment, old structural steel building frames, tin cans, etc.
Recycling is beneficial in two ways: it reduces the inputs (energy and raw materials) to a production system and reduces the amount of waste produced for disposal. These recycled metals have found uses in the production of automobiles, structural steel, aluminum siding, and toys. According to experts, every time a ton of steel is recycled, 2500 pounds of iron ore, 1000 pounds of coal and 40 pounds of limestone are preserved.
