The given diagram illustrates the process of manufacturing aluminium cans.
From a general perspective, it is apparent that the process consists of three primary phases: initially preparation involving collecting and transporting used aluminium cans; intermediate processing focused on recycling them; and the final stage is distributing recycled cans to drinks machines .
At the first stage of the process, used aluminium cans are collected by workers in the collection centre before being stored in designated containers. These collected cans are then transferred to the recycling centre, ready for the subsequent stage of the process.
Once these used cans are transported to the recycling centre, they undergo an initial processing before being melted down in specialised kilns at a high temperature. Subsequently, this melted aluminium then becomes new aluminium ingots and then undergoes a rolling process, creating thin aluminium sheets, which are the fundamental material to manufacture aluminium cans.
The final stage of the process involves distributing and installing these new recycled aluminum cans in drinks machines, ready to be used again.
