Carmeuse is a Belgian producer and supplier of lime and limestone products, founded in 1860 as a single-quarry family operation in Belgium. Headquartered in Louvain-la-Neuve, with a regional headquarters in Pittsburgh, Pennsylvania, the company has grown into a global operation with 6,300 employees, 113 production plants, and 62 limestone quarries and mines spanning nearly every continent. Its subsidiaries include Carmeuse Systems and Mintek Resources.
The company's core business is the production and trade of calcium-based mineral products used across a range of industrial applications, including steel manufacturing, water purification, soil treatment, and air quality control. Carmeuse serves over 8,500 customers annually and has expanded its offering beyond raw materials to include custom engineering services, equipment design, and logistics support - positioning itself as an integrated solutions partner rather than a commodity supplier.
Operations at Carmeuse span several technically demanding disciplines:
- Mining and mineral extraction
- Lime and limestone processing and materials production
- Industrial equipment design and manufacturing
- Custom engineering for industrial clients
- Logistics coordination for product delivery and operational support
Roles across the company's global network - from plant and mine operations to engineering and logistics - involve working within structured, process-driven environments that reward precision, reliability, and applied technical expertise.
