Aluminium can be reprocessed and reformed endlessly, and the metal loses none of its quality during the recycling process.
The metal can be reused in the production of a multitude of different products, ranging from cars to window frames, and from aeroplanes to foil trays. This endless reuse cycle is also known as ‘closed loop’ recycling. For drinks cans collected in the UK the closed loop can mean used cans are reprocessed and remade into more drink cans.
Five stages of the recycling process:
Drinks cans, foil trays and aerosols are typically collected from homes or can banks mixed with food and drink cans made of steel. Some recycling schemes collect foil separately.
The mixed metals will be taken to a waste transfer station or materials recovery facility (MRF) where they are sorted into separate metal streams and compressed into bales.
The aluminium bales are then taken to a reprocessing plant, where they go through four stages – shredding, decoating, melting, and casting. During the final stage, the molten metal is cast into large ingots.
In the UK Novelis operates Europe’s only dedicated aluminium drinks can recycling plant, where cans are reprocessed in a ‘closed loop’ to make metal used for the manufacture of more beverage cans . This plant has the capacity to recycle every aluminium drink can sold in the UK for the foreseeable future.

Ingots are transported to a rolling mill and rolled out to make sheet aluminium, from which new packaging can be made.
Aluminium sheet is converted into a diverse range of packaging items.
