Understanding the Basics of Scrap Metal Recycling
Scrap Metal Recycling

Recycling metal entails recovering and reprocessing metals from various sources, including discarded consumer products, industrial waste, and construction materials. This process reduces waste and minimizes the environmental impact of metal extraction and processing. Here is more information about the basics of scrap metal recycling:


Recyclers collect scraps from automotive workshops, including old car parts, exhaust systems, engine components, and metal body panels. They also collaborate with demolition contractors to salvage metal materials such as steel beams, rebar, piping, and roofing.  Metal recyclers collect scraps from manufacturers, including excess material from metal fabrication, such as metal shavings, trimmings, and defective parts. They also provide dumpsters to construction sites to facilitate the transportation of leftover structural steel, pipes, wiring, and fixtures. Household metal items, ranging from old appliances to discarded metal furniture, are another source of scrap.


Trained workers sort items based on their metal type and content for streamlined recycling. Ferrous metals that contain iron can be found in washing machines, car parts, and steel beams. Recyclers also sort non-ferrous metals, featuring aluminum, copper, brass, and zinc. Non-ferrous metals are in plumbing fixtures, car parts, electrical components, and electronic devices. Some scrap metal recyclers accept and sort breakage, which entails metals and alloys in starters, electric motors, and alternators. Sorting allows recyclers to determine the value of metals to provide more precise estimates and quotations to suppliers.

Cleaning and Preparation

Metal scraps collected from various sources may be contaminated with oils, grease, and other lubricants used during machining, manufacturing, or transportation. Degreasing involves using solvents, detergents, or alkaline solutions to remove these contaminants from the surface of the metal. Degassing is beneficial for aluminum and other non-ferrous metals, as they may contain trapped gases that can affect the quality of the recycled material. After cleaning, experts rinse metal parts thoroughly with water to remove any remaining cleaning agents or residues.

Shredding and Melting

Recyclers use industrial shredders to reduce metal scraps into smaller, more manageable pieces. The shredding process involves feeding metal scraps into the shredder, where rotating blades or hammers tear and shear the material into smaller fragments. Shredding enhances the efficiency of subsequent processing stages by increasing the surface area of the metal scraps. After shredding, experts transport the metal scraps to melting furnaces for processing. Effective melting removes remaining impurities and creates raw metal materials. 

Purification and Alloying

Purification can remove impurities from the molten metal, so the recycled metal meets quality standards and specifications. Adding refining agents may facilitate the removal of impurities in recycled metal. Alloying involves adding specific elements to the molten metal to modify its mechanical, chemical, or physical characteristics. The alloying process enhances the properties of recycled metal, making it suitable for specific applications such as automotive components, aerospace parts, construction materials, and electronic devices.

Work With Reputable Scrap Metal Recyclers

Recycling scrap involves various steps to create quality metal that can be sold to manufacturers to produce new products. Different companies can sell scrap metal to reputable recyclers and earn an income. Contact reputed metal recyclers to learn more about the scrap process.
