Ferrous metals are those that contain iron, including wrought iron, cast iron, steel and stainless steel. They are separated from other scrap metal by powerful magnets, as well as sorted by hand. Common sources include cast iron, turnings, old cars, household appliances, steel beams, railroad tracks, ships, food tins, bottle tops, paint cans and aerosols.
Recycling ferrous metals has many financial and environmental benefits. It diverts them from landfill, reduces the need to extract and manufacture raw materials and contributes to significant savings in greenhouse gas emissions. Recycling steel, for example, uses 75% less energy than making steel from raw materials. All types of steel are 100% recyclable and can be recycled an infinite amount of times.
