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.

Our facility in Keeseville, NY, plays a key role in supporting industrial customers by crushing, screening, and packaging International Garnet, a by-product of mineral mining.

By recovering and refining mineral mining by-products, we transform an industrial waste stream into high-value performance materials used for surface preparation, blast cleaning and water filtration. This not only supports customer operations but also helps reduce reliance on virgin raw materials.

This approach reflects Opta Group’s commitment to sustainability, operational efficiency and responsible resource management. We are creating value from materials that would otherwise go unused while supporting safer and more environmentally responsible industrial practices.

At Opta Group, we don’t just supply materials, we integrate solutions directly into our customers’ operations. Our hands-on, collaborative approach ensures that every product, process and service we deliver is aligned with our customers’ goals for safety, sustainability and durability.

Every partnership is backed by trusted expertise and a global network of highly skilled engineers and technicians who work side by side with producers to solve critical challenges and continuously advance performance.
