Performance 2025
Carmeuse continued its track record of strong financial performance in 2025, delivering its fourth consecutive year of historical results, with EBITDA growing year-on-year despite divergent volume trends across regions. This performance was underpinned by continued commercial discipline — particularly in North America — as well as rigorous cost control, including the successful implementation of a Strategic Realignment Program in Europe. In parallel, Carmeuse pursued an exceptionally active M&A agenda with five transactions completed, most notably the acquisition of Cementos Bío Bío in Chile, expanding its footprint across North America, South America and Africa, while commissioning new industrial capacity in the Middle East.
Project Butterfly:
Advancing Breakthrough
Carbon Capture
in Lime Production
Carmeuse’s Butterfly project is an innovative carbon capture initiative designed to significantly reduce CO2 emissions from lime production. The project integrates a new kiln concept that enables the separation and concentration of CO2 from both fuel combustion and limestone calcination.
By producing a high-purity CO2 stream suitable for storage or reuse, Butterfly addresses the sector’s hard-to-abate process emissions. Currently in its demonstration phase, the project represents a critical step toward scalable low-carbon lime production and supports Carmeuse’s 2030 and 2050 climate ambitions.
