Sustainability

Why EPDs?

If you want to be a pioneer in terms of sustainability, you must also focus on complete transparency – throughout the entire product life cycle. We lead the way and use EPDs verified by the relevant testing bodies to ensure a good data basis for the ecological assessment of steel as a material.

Annex to the EPD Unger rolled section construction ‘Unger Steel²Zero’:
This declaration refers to 1 tonne of Steel²Zero rolled profile construction and covers constructions made from steel profiles produced using the EAF process from 100% scrap and green electricity.

What is the cycle of steel?

• Steel is infinitely and completely recyclable, in most cases without any loss of quality.
• 85-95 % of old steel at the end of its service life is currently recycled into new steel products and accounts for over 20 % of today’s steel production.
• However, end-of-life steel is just the beginning of green steel – recycled and renewably produced from up to 100 % scrap steel.

We had the honour of welcoming a delegation from the Vienna Technical Museum to our company to discuss one of the most pressing issues of our time:
Sustainability in the steel industry

‘Our vision is clear – through innovative technologies and targeted measures, we want to drastically reduce our carbon footprint and show that economic success and ecological responsibility can go hand in hand,’ emphasises Bernd Mühl, Head of Division Steel.

A big thank you to the Vienna Technical Museum for the exciting dialogue. Together we are taking steps towards a more climate-friendly industry and have started with us!

In the context of the circular economy, the end-of-life balance of building product is important because although buildings are generally long-lasting products, they consume significant material resources and if we do not keep these resources in use through reuse or genuine recycling, the circular economy is lost.

Building materials differ considerably in their service life balance; this depends on both the material properties and the resulting designs.

Value Engineering

Value engineering makes it possible to reduce steel masses through higher steel grades.

CO₂-reduced steel

At Unger, we offer the processing of CO₂-reduced steel. This makes it possible to reduce the CO₂ footprint by up to approx. 70 % using only the raw material.

The junior basketball club GETSGO Stadtschlaining trains over 100 children and young people from more than 10 communities, creating a sporting home for young basketball talents. Girls and boys are equally supported and encouraged in their sporting development — completely free of charge.

A dedicated team of 18 coaches and supervisors ensures that the players receive the best possible support — and all on a purely voluntary basis.

Sporting successes: several state championship and runner-up titles, ASKÖ Burgenland Team 2023, Regionality Award 2024 in the ‘Health and Social Affairs’ category.  

In addition to active match operations, the club also provides its young people with further training in important areas such as refereeing, organisation at the scorer’s table or as prospective coaches.

This holistic commitment symbolises team spirit, responsibility and cohesion. We are delighted to be able to help shape the sport of basketball in our region.
