Recovered steel can be re-melted and used again and again to produce new products. For every ton of steel recycled, 2,500 pounds of iron ore, 1,400 pounds of coal, and 120 pounds of limestone are conserved. Recycling steel saves nearly 74% of the energy used to produce it from raw materials — that’s enough energy to power about 18 million homes for a full year.
Collected at curbside recycling bins, local recycling drop-offs, or scrap buy-back centers.
As material travels along the materials recovery facility (MRF) conveyor belt, a high-powered magnet attracts steel cans to a revolving belt to sort them from other materials. The steel cans are then baled before shipment to a steel mill or foundry.
The scrap steel is melted in a steel making furnace which has a temperature of nearly 3,000 degrees. Steel cans are usually mixed with other scrap metal, like automobile parts.
The melted metal is then cast into slabs and rolled into flat stock or steel sheets.
The flat stock is cut into sections, rolled, and welded into tubes. The recycled steel tubing is then assembled into a bike frame.
