Pyrum steel wire is extracted from the material flow using a powerful metal separation system. Before undergoing cleaning, the steel wire has a purity level of only around 80 per cent due to all the rubber and textile fibres extracted along with the wire and so is not yet pure enough for use in a steel mill.
For this reason, the textile fibres and rubber adhesions are almost completely separated from the steel wires in a second process step. In the end, the Pyrum steel wire has a purity of over 96 per cent in steel mill quality. The rubber residues can be Granules further processed and sent for thermolysis.
Incidentally, every tonne of steel and iron scrap used in steel production avoids the mining of 1.5 tonnes of iron ore.
