Evolution of aluminium recycling in EU (1980-2002)
Recycling of aluminium
Advantages of aluminium recyclingEnergy savesReduction of CO2
Reduction of ore miningReduction 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
Casting Cutting 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.
