FREMONT, CA: Scrap metal recycling is both a process and a foundation for a strong industry. Scrap metal recycling includes removing and reusing scrap metal from end-of-life items or buildings and scrap manufacturing so that it can be introduced as a raw material in the manufacture of new goods. It can be recycled repeatedly without the deterioration of its properties. It offers raw materials for new goods while providing a much smaller carbon footprint and more effective energy use than new materials.
Apart from environmental gains, metal recycling is a compelling economic practice. The U.S. ferrous scrap market was worth 18.3 billion dollars in 2015. U.S. non-ferrous scrap had a valuation of nearly 32 billion dollars in 2014.
When speaking about scrap metal recycling, it is essential to distinguish between the two significant scrap metal types: ferrous metal and non-ferrous metal. Although ferrous metal contains some degree of iron (and thus its name is derived from the Latin word meaning iron), non-ferrous metal does not have iron as a part. Non-ferrous scrap contains aluminum, copper, lead, nickel, tin, zinc, and so on.
The Scrap Metal Recycling Process
The scrap metal method requires a variety of phases. It starts with the collection. At the micro stage, scrap metal collectors pick up tiny amounts of scrap for auction in scrap yards. Metal is often retrieved from larger generators by larger scrap dealers or by roadside recycling. Metals are first processed, prepared for shipping, shredded, and then melted. The purification process can require the use of electrolysis, robust magnet systems, or other technologies.
Advantages of Recycling
Apart from the diversion of products from landfill sites, the other significant advantages of metal recycling versus the generation of pure metal include a decrease in energy consumption and the use of different materials. For instance, recycled aluminum requires 95 percent less energy, while copper needs 90 percent less, and steel needs 56 percent less. In comparison, the recovery of one ton of steel prevents the use of 2,500 pounds of iron ore, 1,400 pounds of coal, and 120 pounds of limestone.
