The European Union recycled 92% of steel slag in 2024, processing 35 million metric tons of 38 million metric tons produced into industrial & construction applications. Blast furnace slag achieved 100% reuse at 21.5 million metric tons, approximately 20 million metric tons granulated for cement production displacing carbon-intensive clinker. Steel slag reached 82% utilization, 9 million metric tons serving road construction applications. This recycling prevented 40 million metric tons of natural stone extraction & avoided 11.4 million metric tons of CO₂ emissions in 2024 alone. From 2000-2024, cumulative benefits totaled 1.21 billion metric tons of stone saved & 319 million metric tons of CO₂ emissions avoided.
