In practice, all metal packaging is recyclable.
Metal packaging is divided into ferrous metals and non-ferrous metals.
Ferrous metals (e.g. steel)
- Sorting with a magnet
- Melting at 1500°C
Non-ferrous metals (e.g. aluminium)
- Sorting via eddy current
- Melting at 750°C
Adding scrap lowers the temperature in the recycling process.
Avoid the use of metal packaging made of different materials, the components of which cannot be separated manually because the non-targeted material is lost to recycling.
Example: a drum made from aluminised steel will end up in the ferrous metals recycling stream. The aluminium is not a pollutant in, for example, the production of steel, but it will no longer be recoverable and is therefore lost for recycling purposes.
