Green steel: sustainable solutions for a better future

Climate change is one of the greatest challenges of our time. As a future-oriented company, we at UnionStahl also actively contribute to reducing CO2 emissions and offer green steel that is produced using special processes with minimal CO2 emissions.

What makes our green steel special?

Use of electric arc furnaces for steel production
Recycling scrap as a key component of the production process
Energy supply from fossil-free sources

Our green steel products are available in exceptional dimensions:

Widths up to 3,800 mm
Lengths up to 14,000 mm

The production and use of green steel is not only sustainable, but also makes economic sense. The demand for low-emission products is continuously increasing, and UnionStahl helps you to position yourself as an environmentally conscious partner in your industry.

Climate-neutral steel production with green hydrogen

The next big step towards climate-neutral steel production is the use of green hydrogen. This innovative approach makes it possible to chemically reduce iron ore without having to rely on fossil fuels. The resulting sponge iron is then processed into high-quality crude steel in electric arc furnaces.

UnionStahl is working closely with leading European steelworks that are actively driving this transition forward. Our goal is to shape the transformation to_CO2-free steel production together with our partners and customers.
