Aluminium scrap are used for recycling process because of their optimam usage, high competitive price, lightness, corrosion resistance and strength. Aluminiums weight generally around a third of the weight of the equivalent sized steel component, with much better corrosion resistance.
Shreeya International offer most grades of Aluminium Scrap like Tense Taint / Tabor, 6063 Extrusions, UBC, wheels, Twitch, Talon, Shredded TT, Aircraft scrap, zorba, etc to various Aluminium Alloy manufactures & suppliers.
Do You Know ?
Aluminium recycling is the process by which scrap aluminium can be reused in products after its initial production. The process involves simply re-melting the metal, which is far less expensive and energy-intensive than creating new aluminium through the electrolysis of aluminium oxide (Al2O3), which must first be mined from bauxite ore and then refined into aluminium oxide using the Bayer process and then refined again into aluminium metal using the Hall–Héroult process.
Recycling scrap aluminium requires only 5% of the energy used to make new aluminium from the raw ore. For this reason, approximately 36% of all aluminium produced in the United States comes from old recycled scrap. Used beverage containers are the largest component of processed aluminum scrap, and most of it is manufactured back into aluminium cans.
Types of Aluminium Scrap
The Challenge :
Recycling aluminum requires only five percent of the energy required to manufacture new aluminum from bauxite. However, recycling aluminum produces many toxic chemicals that are released into the air. Furthermore, recycling aluminum produces a waste product called “dross” that is highly toxic and has to be buried in landfills. This dross must be tightly sealed in containers so that it doesn’t leak out and enter groundwater.
In order to be recycled, aluminum must be melted to separate the pure metal from the impurities. This process produces a waste product that is known as salt cake. For every tonne of aluminum that is melted, 200 to 500 kilograms of salt cake are produced. This “cake” is not something that you would want to eat — it contains aluminium oxides, metallic aluminum, carbides, nitrides, sulphides and phosphides. Salt cake is highly toxic to living organisms.
The Advantage :
Aluminium is an infinitely recyclable material, and it takes up to 95 percent less energy to recycle it than to produce primary aluminum, which also limits emissions, including greenhouse gases. Today, about 75 percent of all aluminum produced in history, nearly a billion tons, is still in use.
The recycling of aluminium generally produces significant cost savings over the production of new aluminium, even when the cost of collection, separation and recycling are taken into account. Over the long term, even larger national savings are made when the reduction in the capital costs associated with landfills, mines, and international shipping of raw aluminium are considered.
The benefit with respect to emissions of carbon dioxide depends in part on the type of energy used. Electrolysis can be done using electricity from non-fossil-fuel sources, such as nuclear, geothermal, hydroelectric, or solar. Efforts are underway to eliminate the need for carbon anodes. The use of recycled aluminium also decreases the need for mining and refining bauxite.
