The Scrap Metal Recycling Process&Benefits of Recycling
The scrap metal process involves several steps. It starts with collection. At the micro level, scrap metal collectors pick up small quantities of scrap for sale to scrap yards. Metal is also recovered from larger generators by by larger scrap dealers, or through curbside recycling.
Metals are then sorted, baled for shipment, shredded, and then melted. A purification process can involve the use of electrolysis, powerful magnet systems or other technologies.
Aside from the diversion of material from landfills, other important benefits of metal recycling versus the creation of virgin metal include a reduction in energy consumption as well as in the use of other materials. For example recycled aluminum requires 95 percent less energy, while copper needs 90 percent less, and steel 56 percent less. Additionally, the recycling of one ton of steel avoids the use of 2,500 pounds of iron ore, 1,400 pounds of coal and 120 pounds of limestone.
