Resource valorization means turning by-products into valuable resources. This approach supports environmental stewardship, strengthens circularity, and creates long-term value. At Lhoist, we apply this approach responsibly, particularly in the management of limestone.
Resource valorization involves reusing, recycling, repurposing, and commercializing by‑products so they can become new raw materials, chemicals, fuels, or energy sources. By doing so, we maximize the utility of natural resources and contribute to a circular economy.
Customer satisfaction
We aim for zero unvalorized materials. By transforming useful resources into marketable products, we create value for our customers and support long-term partnerships.
Environmental Management
Resource valorization reduces our environmental footprint and supports a more circular industry. Our quarries operate under detailed long‑term plans to ensure responsible resource management and reliable service.
We identify by-products early, reduce their creation through more efficient kiln technologies, and optimize process control to maximize first-grade output. Whenever possible, we recycle co-products back into calcination processes or other processes through hydration or briquetting.
We continuously work to eliminate non-valorized materials, seeing them not as waste but as opportunities. This approach mirrors our zero-harm safety ambition and ensures every resource is used to its full potential.
