Our Performance Additives division is advancing sustainability and performance across construction, coatings and surface preparation. Building on the legacy of Opta Minerals, our solutions harness recycled materials and innovative processing technologies to reduce environmental impact and deliver measurable performance improvements in critical industrial applications. We create ultra-fine milled glass materials from post-consumer recycled glass, transforming waste into value-added additives for high-performance concrete. In addition to our ground glass pozzolans we support sustainability through silica-free abrasives and environmentally friendly filtration media that promote safer work environments and cleaner water systems.
Transforming waste into sustainable performance materials.
Our investment in a world-leading recycled glass processing facility in Ontario, Canada, OPTA Glass now operates the largest glass recycling operation of its kind, capable of treating up to 165,000 tons of post-consumer recycled glass annually. Using a state-of-the-art proprietary milling system, we produce ground glass pozzolans from post-consumer and industrial glass streams providing low-carbon construction materials that perform better and last longer.
