What Carmeuse Group does

Carmeuse Group is a privately held, Belgium-headquartered industrial company that produces lime, high calcium limestone, and dolomitic stone for B2B customers across multiple sectors. Its lead vertical is iron and steel, where its products support iron ore preparation, sintering, hot metal desulphurization, BOF and EAF steelmaking, and secondary metallurgy; other verticals include civil engineering and construction, agriculture/feed/food, environmental applications (water treatment, flue gas cleaning, sludge and soil treatment), chemicals, PCC/pulp and paper, and building materials. The group operates across 35+ countries with approximately 6,300 employees, anchored by regional operating subsidiaries (Carmeuse Americas, Carmeuse Europe, Carmeuse Czech Republic) and an extensive quarry and processing footprint that includes Drummond Island and Cedarville in Michigan, Mokrá in Czechia, Salalah in Oman, and Liége in Belgium.

The company runs an enterprise field-sales go-to-market with dedicated customer support and field support teams, supplying not only core mineral products but also customized equipment and engineering solutions for plant, storage, and product transfer needs. Revenue is generated primarily through hardware/product sales of quicklime, hydrated lime, calcium carbonate, and specialty mineral-based solutions, sold in formats ranging from 0.5kg and 25kg packs for agricultural brands like Optilit, up to 600–1,200kg big bags and bulk shipments for industrial customers; pricing is quote-based for B2B and not publicly disclosed. The product portfolio is organized around registered brands including AquaCalco and AquaCalco W for environmental water treatment, TerraCalco (95, 55, Garden) for agriculture, Optilit for livestock hygiene, NutriCalco for animal nutrition, and ViaCalco, Calcitec, SuperCalco, Enduria, PremiaCal, StabiCalco, CleanCalco, SanaCalco, LeafCalco, and FruitCal for civil engineering, building materials, and specialty applications.

In 2025–2026 Carmeuse executed an active inorganic growth and modernization program: acquisitions of Al Namariq (Oman, 2026-01), PB Lime / Carmeuse South Africa (2026-02), Unicalce in full from the Gnecci Family (Italy, 2026-02), Crandell Brothers Trucking and Omni Materials (US, 2026-02), and Cementos Bío Bío (Chile, 2025-09); creation of the CarVal Biomass joint venture with Terval in Belgium (2026-05) for biomass pellet grinding; deployment of Caterpillar MineStar autonomous haulage at Drummond Island (2026-05) and Intramotev TugVolt autonomous railcars at Cedarville (2026-01); partnerships including the Bellona Center for Marine Restoration (2025-06) and the Holcim-led Carbon Hub CPT01 EU Innovation Fund project (2025-11); and venture investments in carbon-capture startups pHathom Technologies and Planeteers via Carmeuse Ventures. The group is led by CEO Rodolphe Marie Collinet with COO Yves Willems, CFO Yves Schoonejans, CHRO Danielle Knott, and Deputy CEO Sebastien Dossogne.
