Science Day: Innovations in the Circular Economy

18.06.2025 - Aula Academica, TU Clausthal

Green steel - the path to climate neutrality

Ladies and gentlemen, students, researchers and experts,

For 250 years, Clausthal University of Technology has stood for pioneering research in the development of technologies and methods for the sustainable management of resources: raw materials, materials, energy and information. In times of geopolitical and ecological change, the steel industry is also facing major challenges. We are delighted to welcome GMH Gruppe and Salzgitter AG, two key players in the steel industry, as main sponsors of the festival week.

The Science Day will shed light on the challenges posed by the transformation of the steel industry towards a circular economy. In exciting presentations, experts from science and industry will provide an insight into a wide range of solutions that are being developed and used on the way to a climate-neutral steel industry.

Exchange ideas with experts, scientists and students at the accompanying get-together including a poster and company exhibition.

We look forward to your participation!
