Group-wide recycling

Group-wide recycling

Closed cycle

Scrap is the basis of GMH Gruppe’s steel production: Our steel is melted from 100% scrap. This makes our raw material recycling the pivotal point of our sustainable circular economy – not only at the individual location, but also across locations within GMH Gruppe, as the example of Mannstaedt shows.

Inter-company material cycle

Hundreds of tonnes of profile scrap arise every month at Mannstaedt GmbH in Troisdorf. Unavoidable new scrap that results directly from production and processing. But even this new scrap is recycled and reused within GMH Gruppe to protect the climate and save resources. For example, since 2006 our profile scrap has been shredded and transported in a climate-friendly way by rail from Troisdorf to Georgsmarienhütte.

There, at the GMH Gruppe location, it is prepared by GMH Recycling GmbH into feed material for Georgsmarienhütte GmbH’s electric arc furnace, where it is made into new steel. That steel is then delivered back to Mannstaedt GmbH - again, by eco-friendly rail transport - as high-quality, semi-finished products, which Mannstaedt processes into special profiles – thus closing our internal material cycle.

Benefits of inter-company recycling

  • Our inter-company business makes a valuable contribution to climate protection: short transport routes between the group locations and the transport exclusively by rail avoid CO2 emissions and other negative effects on the environment.
  • Recycling enhances resource, energy and material efficiency.
  • The EAF is fed with 100% correctly sorted Type 2 production scrap.

Win-win situation, also for the climate

The fact that we recycle about 1,000 tonnes of scrap in this way every month is just part of our sustainable success story, as in total about double that amount of profile scrap arises from the operations at Mannstaedt GmbH. In the past, that half of the scrap used to be prepared by external partners as material for the foundry market. But now, we have also integrated that part into GMH Gruppe, via a joint project with GMH Recycling GmbH. This means that now 100% of the scrap remains within a closed recycling loop which provides benefits not only for the climate and the environment, but also for our steel production: we can be sure that we always receive as feedstock for our electric arc furnace correctly sorted, homogenous Type 2 production scrap - the basis for ever new, high-quality steel products.
