Recorded live at the Decarb Connect UK Summit in March, this episode features guest host Tom Angus, Senior Conference Producer at Decarb Connect in conversation with Eoin Bailey, Innovation and Circular Economy Manager at 7 Steel UK. Eoin shares his journey from automotive design engineer to steel industry innovator, and unpacks how 7 Steel is embedding circular economy principles to deliver more sustainable steel solutions for the UK construction sector.

*Please note: At the time of recording, 7 Steel UK was operating as Celsa Steel. Throughout the episode, you’ll hear it referred to by its former name.

Highlights from the conversation:

• Career evolution: How Bailey’s experience analysing product lifecycles sparked his focus on applying circular economy thinking in steel production.
• Circular steel in action: Celsa’s use of electric arc furnaces to recycle scrap steel into new construction materials, creating a closed-loop system that links demolition directly to procurement.
• Overcoming systemic barriers: The challenges of moving from linear “take-make-waste” models toward circular systems that extend material value and cut environmental impact.
• Green premiums and market positioning: Bailey's perspective that low-carbon steel shouldn't command premium pricing when it's produced as standard practice, emphasising the importance of transparent environmental product declarations
• Collaboration & policy shifts: The crucial role of industry collaboration and public sector policies in ensuring local, low-carbon steel competes with cheaper imports.
