Excellent, global logistic capabilities

Produced in seven countries, delivered as crystal or liquid to pulp mills and industries worldwide.

Over 90% of all sodium chlorate (NaClO3) produced worldwide is used by the pulp and paper industry to generate chlorine dioxide – the critical component in elemental chlorine-free (ECF) pulp bleaching. Sodium chlorate is also used by many other industries as a specialty oxidant.

From production facilities in Brazil, Canada, Chile, France, Finland, Sweden and USA, we package and ship sodium chlorate, under the brand name Eka® SC. We can deliver both crystal and liquid form, in bulk (railcars and tanker trucks) and big bags/supersacks.

Our excellent, global logistic capabilities include transportation by road, rail, sea or air (sample quantities only) according to specific packaging, vehicle and documentation requirements.

Reduced carbon footprint - manufacturing facilities close to our customers

We produce sodium chlorate by electrolysis of brine, an energy-intensive, multistage process run in closed-loop plants that keep emissions to a minimum. Our proprietary electrode design cuts electrical power consumption while maintaining product quality. The process also yields hydrogen gas, which many pulp mill customers use to replace fossil fuels or sell to other partners.

Wherever possible, we locate plants where renewable energy is available. At our Integrated Manufacturing Model facilities, we build next to customers and chlorine dioxide production, where bio-based energy powers chlorate production.
