Nouryon commissions chlorine dioxide plant for Arauco’s MAPA project in Chile

20 Mar 2023 - News

Nouryon announced that it has commissioned a chlorine dioxide plant to modernize and expand the Arauco pulp mill in Chile. The project, called the MAPA project, is a $2.35 billion pulp mill and is the largest industrial project in the Biobío region. The new plant adds 1.56 million tons per year of eucalyptus pulp capacity to Arauco’s footprint that will be supplied to its customers.

“At Nouryon, we are committed to meeting our customers’ needs by providing them with innovative and sustainable solutions that optimize their manufacturing footprints. We are pleased to partner with Arauco in the commissioning of the plant to meet the growing global demands of the paper and pulp market,” said Eduardo Nardinelli, Senior Vice President, South America & Global Carbon Business Leader at Nouryon.

Nouryon is a technology leader in the production of chlorine dioxide. With ever-increasing pressure on pulp mills to control costs and optimize systems, the safe and optimized use of chlorine dioxide during the production of pulp is critical. For Arauco's MAPA project, Nouryon has led the design, construction, and start-up of the onsite chlorine dioxide plant, enabling essential raw materials needed in pulp production to be supplied directly into Arauco's pulp mill.

“We are very proud of the completion of this project as it demonstrates the long and positive work we have done together with our community, authorities, and partners where Nouryon has been instrumental in the important step for pulp production. The MAPA project is a hugely symbolic project for the country and the Biobío region and will allow us to modernize and increase the production efficiency of our facilities,” said Charles Kimber, Corporate and Commercial Affairs Manager at Arauco.

“The MAPA project in Chile is another example of how our long history of designing and building chlorine dioxide plants enables us to effectively support our customers locally with sustainable solutions. The new onsite plant will reduce transportation emissions, and facilitate safe and reliable operations for Arauco,” said Ann Lindgärde, Vice President Renewable Fibers at Nouryon.
