AMG sends most of the tin and the steel to steel firms in the UK or abroad, such as Corus or Celsa.
They put it to different uses. At Celsa, in Cardiff, it is generally made into bars and other products for the building industry.
The aluminium goes to Novelis in Warrington, where it is turned into coil and sold to can makers in the UK or abroad.
One such firm is Ball Packaging in Wrexham, which takes 17 steps to turn it into cans for drinks such as Guinness or Coca-Cola.
