Steel is one of the few structural materials with a genuinely viable circular pathway — and yet most of it still gets melted down rather than reused. A steel section recovered intact from a building and reinstalled elsewhere retains its full structural value and avoids almost all of its embodied carbon. Melt it instead, even in an Electric Arc Furnace, and you still burn energy and lose the geometry. The hierarchy is clear: reuse first, then recycle.
On the production side, the shift from blast furnaces to Electric Arc Furnace technology — which uses recycled scrap rather than virgin iron ore — offers a proven pathway to reducing emissions by up to 95% (source: RECYCLING magazine). Producers like Swiss Steel Group are already operating entirely on EAF, with emissions up to 83% lower than the industry average (source: Green Steel). The European Commission’s Joint Research Centre estimates the EU could unlock an additional 20 to 40 million tonnes of high-quality scrap annually — over half of current EU scrap consumption — if collection and sorting infrastructure improves.
On the reuse side, companies like EMR in the UK are already offering structured steel recovery services — identifying steel sections that can be harvested from buildings before being tested, surveyed, and converted into ultra-low carbon reusable sections — with carbon reductions of up to 97.5% compared to new production. The bottleneck is not the steel. It is the absence of pre-deconstruction planning, testing protocols, and demand-side confidence from engineers and structural designers.
So: what is your experience with steel on circular projects? Are you specifying low-carbon or recycled steel with EPDs? Has anyone worked with reused structural sections — and what did testing and liability look like in practice? Are there suppliers or services in your country doing this well?
