24 Aug. 2026: Across the pulp and paper industry, producers are under growing pressure to reduce landfill dependency, improve circularity and respond to evolving regulations and sustainability expectations. Mineral-rich side streams such as lime mud, grits, de-inking sludge, wastewater sludge and fly ash can be costly to dispose of and are often underutilized.

ATMIRE is designed to meet these challenges on the mill site. This technology platform processes side streams into recycled calcium carbonate grades and other value-added materials, helping mills reduce disposal costs, support sustainability goals and close the loop on raw material use.

A practical path to circular mineral recovery
ATMIRE brings Omya’s on-site expertise into mineral recycling through a platform designed for practical implementation at pulp and paper mills. It can be integrated into existing Omya on-site plants or deployed as a standalone unit, supporting both greenfield projects and retrofits. From there, recycled product properties can be tailored to customer needs and target applications.

Different streams. Different solutions. One circular platform.
Mineral-rich side streams vary in composition, purity, and potential end use. ATMIRE addresses this complexity through three dedicated pillars, matching each material stream with an appropriate recovery or valorization approach. Together they create a flexible platform for circular mineral solutions in pulp and paper operations.

• White – for calcium carbonate rich materials such as lime mud
• Blue – for blended waste like de-inking sludge
• Orange – for processed waste such as fly ash

Why ATMIRE
ATMIRE helps mills turn circular ambition into operational value. By recovering useful minerals on site, the platform can reduce disposal spend, support more efficient raw material use, and strengthen sustainability performance while maintaining a dependable supply approach tailored to each mill’s needs.
