Recycling scrap metal not only saves manufacturers money but also decreases energy consumption, and with large energy savings, consumers obtain cheaper items while greenhouse emissions are reduced, making it a true win-win situation.
Fremont, CA: Metals, unlike most other materials, can well be recycled multiple times without losing their qualities. Steel is the most recyclable material on the earth for this reason. Scrap metal recycling contributes to both a financial incentive and an environmental obligation.
The steps in the metal recycling process are as follows:
Remove all extraneous items, such as plastic or paper, from the metal. As a general rule, a product must include 50 percent or more metal, therefore set aside any goods that meet this criterion. Use a magnet to determine which goods are ferrous and which are non-ferrous after that.
Metal is gathered through scrap metal collectors, as well as curbside recycling services, major generators, and scrap dealers. Most curbside and public recycling systems only accept common household metals like cans, not the complete range of recyclable metals. Scrap recyclers can help with this.
Visual identification, spectrometers, magnets, and electrical currents are among the methods used by scrap yards to sort and separate metal. Metals should be kept together because they must fulfill specific quality criteria, which means no cross-contamination with other metals or minerals.
Processing into forms
Metals must be chopped down to certain sizes and forms to make the melting process more efficient. Once the metal has been sized and processed, it is delivered to the next client in the chain: foundries, mills and smelters that use scrap to produce new metal.
Melting and refining
The technique for melting down scrap metal varies depending on the metal and the amount of purity required. Impurities ascend to the top of melted metals, where they can be separated from the remaining metal. Some metals undergo further refinement, such as electrolysis, to produce a product that is as near to primary or fresh metal as feasible.
Molten metal is altered as it solidifies after being cleansed of pollutants. It can come in various shapes and sizes, and plants specialize in the types they produce. Chemicals are sometimes added to metals to make them denser or change their characteristics. The metal is ready to use after the solidifying cycle is completed.
The new metal is usually not used by the foundry or mill. It then moves on to other industries such as automobiles, robots, aerospace, public works projects, and a wide range of consumer items. The lifecycles of those products can be extended by repair and reuse until it's time to recycle them again.
