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 ( Al 2 O 3 ), which must first be mined from bauxite ore and then refined using the Bayer process .
Total aluminum sector energy use accounted for over 300 trillion British thermal units in 2006. Primary processing includes processing raw materials and manufacturing aluminum. The subsector secondary processing includes melting scrap. The other two subsectors are downstream products that can be made either from primary or secondary aluminum.

The aluminium production process affects our environment in several ways. Large amounts of natural resources are extracted or modified from coal, oil, gas, and hydroelectricity dams for energy generation during the manufacturing aluminum. The refining of bauxite into alumina is also a water-intensive process. In 2007 2.5 kilolitres were used for every tonne of alumina production. Aluminium ...

Aluminium is a very useful metal; it is the most widely used non-ferrous* metal in the world. It has a very low electrical resistance and a very good strength-to-weight ratio and has therefore found many applications: from packaging in drinks cans and foil wrapping to aeroplane parts and power lines.

Bauxite mining requires relatively low energy inputs, compared to other steps in the aluminium production process – with less than 1.5 kilograms of fuel oil (mainly in the form of diesel for haul trucks) and less than 5 kWh of electricity consumed per tonne of bauxite extracted.
