Exploring by-product valorization
Population growth and rapid urbanization are putting unprecedented pressure on natural resources, disrupting traditional consumption and production models. Industry now faces the challenge of meeting growing demand while reducing its environmental impact, conserving finite resources, and minimizing waste.
We are committed to contributing to the circular economy and developing products and services with reduced environmental impact through out their life cycle. We strive to find innovative outlets for our low-grade ores, valorizing our own and our customers’ production residues, integrating bio-sourced, reclaimed raw materials or selecting ingredients with lower product carbon footprint (PCF). We collaborate with our ecosystem of partners to leverage our synergies and explore innovative solutions together.
Key material initiatives & low-emission processes
- Seitim - A joint venture with French start-up, Seitiss, to offer circular economy solutions that recycle mineral waste from industrial activities.
- SU-NERGY™ - A high-performance graphite solution derived from forest residues, with a 60% lower carbon footprint than fossil fuel alternatives.
- Polwhite LOOP™ - The first kaolin to be certified as "Circular material" by ISCC PLUS for improving barrier properties in tire inner liners. Imerys is the first minerals producer to achieve ISCC Plus certification.
- Remined™ - A portfolio of 100% UL- and LEED-certified pre-consumer recycled calcium carbonates from the USA, designed for use in carpet, flooring, mortars and adhesives.
- Utilizing post-industrial feed materials, such as mineral by-products in the ceramic industry.
- Using recovered glass in mineral wool products to cut CO₂ emissions while maintaining thermal performance.
By combining material innovation with circular approaches, we help industries use resources more efficiently, reduce their carbon footprint, and move toward more responsible and sustainable production systems.
