Aluminium is a material with a potentially infinite lifespan. Through processing aluminium profile waste, we obtain iron, aluminium and inert materials. The process starts with crushing and shredding of the aluminium, separation of ferrous and non-ferrous metals and of inert components such as plastic and rubber. The aluminium returns to the foundry and becomes new high-quality material for the construction sector in particular. Recyclable aluminium objects are marked by the ‘Al’ or ‘alu’ symbol.
