Metal Recycling in a Nutshell

Metal recycling conserves natural resources while using less energy than manufacturing new items from virgin raw materials.

Fremont, CA: Metals can be recycled multiple times without losing their characteristics. Steel is the most recycled material on the planet, according to the American Iron and Steel Institute (AISI). Aluminum, copper, silver, brass, and gold are highly recycled metals.

Metal recycling conserves natural resources while using less energy than manufacturing new items from virgin raw materials. Recycling reduces the amount of carbon dioxide & other hazardous gases emitted. More importantly, it saves money and enables manufacturing companies to lower their production costs. Recycling also generates employment.

Steps involved in the metal recycling process

Collection

Because of the higher scrap value of metals, the collection method differs from that of other commodities. As a result, it is more likely to be sold to scrap yards than disposed of in a landfill. Scrap autos are the most common source of ferrous scrap metal in the United States.

Large steel constructions, railroad tracks, ships, farm equipment, and, of course, consumer scrap are among the other sources. Prompt scrap, generated during the fabrication of new products, accounts for one-half of ferrous scrap supply.

Sorting

Sorting is separating metals from combined scrap metal or mixed multi-material waste stream. Magnets and sensors are utilized in automated recycling systems to aid material sorting.

Scrappers at the entrepreneurial level may use a magnet and observe the material color or weight to help detect the metal kind.

Processing                                                                                                                                        

Metals get shredded to enable further processing. Shredding is helpful to speed up the melting process because little shredded metals have a high surface-to-volume ratio.

As a result, they may get melted with far less energy. Aluminum is often formed into miniature sheets, whereas steel gets formed into steel blocks.
