Aluminum Recycling

At the end of the lifecycle of a product, the aluminum contained in it can be reused. From this point of view aluminium is not “consumed” during the utilization and therefore can be reutilized again and again. The high amount of energy necessary to produce the aluminium from the raw material alumina is stored in it, hence the used aluminium, or scrap aluminium retains a lot of the initial value.

This is the main reason why aluminium is recycled. There is also another reason, who involves economy and ecology. The recycling of aluminium requires only 5% of the energy necessary to smelt it from the alumina, so it is cheaper. For the same reason, only 5% of greenhouse gases are emitted during aluminium recycling compared to producing primary aluminium.

Presently, primary aluminium production is responsible for 1% of the total greenhouse gases emitted. Of this 1%, 40% is generated by the smelters and 60% is generated by the powerplants producing the electric energy for the smelting process.

If properly treated and sorted in advance, aluminium scrap can be used to produce all kinds of goods, sometimes at lower costs considering that aluminium scraps already contain part or all the alloying elements need to produce the required aluminium alloy.

Aluminium recycling plants are found everywhere in the world, but are primarily located in Europe, USA and Japan, who has stopped primary aluminiu production in the 80s after the increase in energy price.
