- Aluminium cans are shredded, removing any coloured coating.
- They are then melted in a huge furnace.
- The molten metal is poured into ingot casts to set. Each ingot can be made into around 1.5 million cans.
Aluminium foil is a different alloy and is usually recycled separately with other aluminium scraps to make cast items such as engine components, where it makes a big contribution to making vehicles lighter and more energy efficient.
