Evolution of aluminium recycling in EU (1980-2002)

Recycling of aluminium

Advantages of aluminium recycling

Energy saves

Reduction of CO2

Reduction of ore mining

Reduction of aluminium scrap

Last years showed that amount of aluminum that comes from recycling grows.

Machining

Milling

TurningDrilling

Around 5% of primary aluminium is a machining waste

Conventional method of aluminium recycling

CastingCutting of

ingotMelting

Very expensive and big amount of waste is generated.

The finer elements are being melted the bigger material loss is being generated because of burns.
