Turning scrap into excellence,
into climate action

From crude steel to ready-to-install components: steel products that add sustainable value

We are shaping the future of steel by placing sustainability at the heart of our manufacturing processes. Our closed-loop system produces green steel that benefits our customers and our planet.

Recycling scrap

Scrap as the foundation of our steel value chain

Scrap is the basis of our steel production: our high-tech products are made from almost 100 percent scrap metal. In this way, we avoid mining new raw materials and conserve our natural resources. We process steel scrap, special scrap and non-ferrous metal scrap so that it can be reused. We also make use of recirculated scrap such as offcuts and shavings in our steel production process.

Steel scrap

We reuse unalloyed steel scrap directly in our steelmaking plants as a raw material for new products.

Special scrap

We break down ferrous byproducts from pig iron and steel production into weights and sizes suitable for use in a furnace.

Foundry scrap

We supply foundries with processed recycled raw materials tailored to their requirements.

Alloyed steel scrap

In addition to its iron content, alloyed steel scrap contains components that make the steel more resistant to heat and corrosion.

NF metal scrap

Our portfolio also includes NF scrap, i.e. all scrap made from non-ferrous metals.

Grinding sludge

We process grinding sludge in our briquetting plant ready for material recycling in steelworks.

The electric arc furnace

Our climate champion

We produce steel from recycled scrap in the most sustainable way possible: in an electric arc furnace. Compared with traditional blast furnaces, it emits less CO₂, consumes less energy and minimizes harmful air pollutants. In addition, the electric furnace can be flexibly controlled based on demand, without being tied to continuous operating cycles like integrated steelworks. Increasingly, we rely on renewable energy sources to operate our furnace, thereby continuously improving our carbon footprint.

1 Melting:

The scrap is melted down in the electric arc furnace. The electric arc between the graphite electrodes reaches temperatures of up to 3,500 degrees Celsius.

2 Tapping:

The molten steel runs into the ladle through a refractory tube in the furnace floor. The addition of alloying elements gives the steel exactly the right properties for the customer’s end product.

3 Continuous casting process:

The molten steel is then cast without interruption.

4 Flame cutting machine:

Depending on the customer’s specifications, the steel is cut using either continuous or ingot casting, cooled in the turning bed and checked for quality in the finishing area. After this, it is ready to be dispatched.

Green Steel products

From crude steel to
high-tech steel

We supply steel products that have been processed to various levels – as several sustainable Green Steel variants that all meet the highest quality standards.

Discover our products

Crude steel products

We supply crude steel products in ingot and continuous casting formats – with high-nitrogen alloying or electrical remelting for exceptional purity, on request.

Hot-rolled products

We produce hot-rolled steel products in our plants. In addition to round steel bars, we also offer special profiles in a wide range of geometries, with the option of further processing.

Forged products

GMH Gruppe brings together a wide range of forging expertise under one roof, with skills in series and single-piece production, closed-die forging and open-die forging.

Cast products

We support you with the best cast iron and steel solutions along the entire value change, from model to ready-to-install component.

Other components

Our mechanical manufacturing expertise sets standards. We manufacture components of the highest quality to your exact specifications.

Recycled products

We supply steelworks and foundries with high-quality steel, non-ferrous (NF) and alloyed scrap, as well as steel mill byproducts that have been processed competently and safely.

Maximum sustainable
value creation

Our aim is to productively reuse resources and materials over and over again, to take full advantage of synergies along the entire value chain. This is why we rely on integrated product and energy cycles in our value stream, which we are constantly improving.

Conserving resources, reducing waste

We efficiently reuse byproducts. For example, we reprocess slag for road and railroad construction or steel production. And we pass on filter dust to production plants in other industry sectors. We also reuse process water from production, for example for slag cooling. All these initiatives help to conserve resources and reduce waste.

Using waste heat

For us, waste heat is not a waste product, but a source of energy. We reuse it in steel production, to heat buildings, and for heating water. This covers a large part of our total energy requirements and in turn saves many tons of emissions. We also feed waste heat into Georgsmarienhütte’s municipal district heating network.

Short distances, climate-friendly transportation

We keep travel distances as short as possible, saving time and further reducing CO₂ emissions. Long-distance routes are eliminated thanks to the in-house production setup at our Georgsmarienhütte site. Wherever possible, we also rely on rail as the most climate-friendly means of transportation.

Our path to CO₂-neutral steel production

We have made a promise to ourselves and future generations: By 2039, our steel production activities will no longer produce any CO₂ emissions (Scope 1+2).
