Next, the cans undergo a de-lacquering process to remove the external paint and internal lacquer. This step involves a rotary kiln with a gasification system that transforms the paint on the cans, along with any wood or plastic residues that might have slipped in, into fuel. This generates heat, which is then recirculated back into the kiln, significantly reducing the need for additional fuel.

The gasification system is advantageous because it reduces pollution from the burning process and efficiently eliminates paint, recirculating the pollutants and heat back into the kiln, which minimizes energy consumption. This de-lacquering method is not only efficient and quick but also ensures the chemical properties of the aluminium are suitable for manufacturing new aluminium cans.
