Clariant stock is linked to a catalyst milestone in Georgia. EnviCat NSCR surpassed emissions targets at a nitric acid plant.

Catalyst performance strengthens Clariant profile

EnviCat NSCR reduced nitrogen oxides and nitrous oxide at a Georgian nitric acid plant.
The project used existing reactor infrastructure and was designed to limit capital-intensive modifications.
The catalyst update adds a sustainability-focused operating milestone alongside Clariant's specialty chemicals portfolio.

Clariant's EnviCat NSCR catalyst exceeded emissions reduction targets at the Rustavi Azot nitric acid plant in Georgia, according to World Fertilizer in a report published Friday, November 13, 2026.

The honeycomb catalyst reduced nitrogen oxides by 98.97 percent and nitrous oxide by 97.8 percent in operation. Both results exceeded the 95 percent performance targets cited for the project.

Existing infrastructure limits project burden

The installation required only minimal modifications to the plant's existing reactor infrastructure. The setup was developed with engineering partner Alvigo and received partial support from the Nitric Acid Climate Action Group, part of Deutsche Gesellschaft für Internationale Zusammenarbeit.

Rustavi Azot had been using an ageing high-palladium-loading alumina catalyst. Clariant and Alvigo presented the EnviCat NSCR solution as an alternative to a complete unit revamp or replacement with conventional granulated catalysts.

Clariant stock traded at 11.94 euros on Lang & Schwarz at 18:30 CET on Friday, November 13, 2026.

Specialty chemicals portfolio gains proof point

The Georgia project gives Clariant a customer example for emissions control in nitric acid production. The company says the catalyst is designed for tail-gas temperatures above 400 degrees Celsius and uses methane to convert nitrogen oxides and nitrous oxide into nitrogen and water.
