Aluminum is a material with a potentially infinite life. By disposing of the waste of the aluminum profile, iron, aluminum and inert are obtained. In the recycling of aluminum we start from the volumetric reduction, we proceed with the shredding of the material itself, finally we proceed in the treatment with the separation of ferrous and non-ferrous metals and inert components such as plastic and rubber. Finally, aluminum returns to the foundry and becomes a new quality material, especially used in the construction sector. All aluminum objects that can be recycled are marked with the initials ‘Al’ or ‘alu’.
