1.
Steel objects for recycling are collected from can banks, or from kerbside recycling boxes. They are sorted and then returned to the steelmaking plant.
2. The steel is melted down, together with other ingredients called iron ore and limestone.
3. The liquid metal is poured into a mould and then left to cool down. When it's hard enough, a machine chops it into big blocks. These
are taken away to be made into new steel products.
