GMH Gruppe Green Steel

Decarbonisation pioneer in the steel industry: With Green Steel, we’re one step ahead when it comes to sustainability.

Future-oriented solutions

GMH Gruppe Green Steel makes our customers’ products more sustainable – thanks to climate-friendly production processes, even today:

Each tonne of crude steel from our electric arc furnace causes 80 % less CO2 emissions than comparable steel from integrated steelmaking routes. We use 100 % scrap as feedstock. Our value stream saves emissions thanks to climate-friendly logistics. New sustainable measures and innovative products are constantly being added. Above all: We have a clear, realistic roadmap for how we will produce our already low-emission steel in a completely climate-neutral way by 2039.

The optimal strategy

Climate-neutrally produced steel is realistically feasible by 2039 with our electric arc furnace. We will reduce the few currently unavoidable emissions from our production to zero. To this end, we are working in parallel on three key issues: “Green electricity for green steel”, “From natural gas to green hydrogen” and “Biomass instead of coal”. We explain how, here:

Our strategy

Key technology: Electric steel

Electric arc furnaces emit five times less CO2 than blast furnaces and converters. We have been using EAF technology for over 25 years. Find out why this still makes us a pioneer in the industry today, here:

Our electric arc furnace

100% scrap as foundation

We use more than twice the industry average amount of scrap to make excellent products. Read how we’re unburdening the climate and environment with sustainable cycles:

Our recycling economy

Efficient value stream

With short routes, we save countless truck kilometres every year. In addition, efficient processes and innovative products reduce emissions during the further processing of our steel. We’ll show you how:

Green Steel

Our Green Steel logo combines all the measures that make products more sustainable for our customers.


Measures: We are always improving

  • We use the growing infrastructure for green electricity and hydrogen in Europe
  • We are further expanding our recycling of mineral secondary materials
  • We are continuously working on reducing our energy requirements
  • We regularly have our energy management system externally certified according to ISO 50001
  • We actively involve employees, e.g. through our company suggestion scheme and training courses at the GMH Akademie.
  • We have established a sustainability management system connected to management as an executive department which, together with other management systems, coordinates all sustainability issues
  • We develop steels that enable leaner processes in further processing, which reduces emissions MORE INFORMATION →
  • Our steels also save emissions during their use MORE INFORMATION →
  • We rely on state-of-the-art technologies that clearly go beyond the legal requirements MORE INFORMATION →
  • We use our waste heat for our processes and feed it into district heating networks MORE INFORMATION →
