Steel reimagined: CO₂-optimised solutions for the construction industry
Steel is one of the most important materials of our time and a key driver of more sustainable construction. This is precisely where our exhibition space in the Circle Cube comes in.
Located at the harbour between Offenbach and Frankfurt, the Circle Cube brings together stakeholders who are rethinking construction and makes circular solutions in the building industry tangible – from innovative materials to functioning material cycles.
A key element in this is reinforcing steel as part of the circular economy.
It is fully and infinitely recyclable – and in Germany is already produced predominantly from scrap steel. Production in electric arc furnaces (EAFs) in particular allows for a high proportion of recycled material, making reinforcing steel an established circular building material.
With STOOX, we are taking it one step further:
Our CO₂-optimised reinforcing steel is based on the targeted selection of materials with a reduced carbon footprint – combined with clear and traceable data.
- Transparency regarding CO₂ emissions
- Verifiability of the actual delivery
- Extended system boundaries right up to delivery to the construction site
In this way, we enable reliable CO₂ accounting for construction projects and actively support our customers in making climate-conscious decisions.
As the SÜLZLE Group, we are committed to sustainable solutions across the entire value chain – with over 145 years of experience in the steel and infrastructure sectors.
Visit us at the Circle Cube and discover how CO₂-optimised steel is helping to shape the future of construction.
