Paper-based packaging firm Smurfit Kappa is set to carry out a series of upgrades to its flagship kraftliner mill in Piteå, Sweden.

The company will work on increasing the sustainability and efficiency of its cooking plant and recovery boiler at the kraftliner facility in a bid to further reduce emissions.

It will also install high-spec purification filters and an advanced combustion system at the facility.

Piteå Paper Mill CEO Per Sward said: “This latest investment is a very positive step for the mill. The upgraded cooking plant and recovery boiler will unlock pulp production and pulp quality and help us to become even more efficient, which will benefit both our people and the wider community.”

The packaging company is expected to perform these upgrades during a planned 15-day closure of the mill next month.

“Sustainable innovation plays a vital role in ensuring that the communities surrounding our sites are part of our long-term vision.”

According to the company, the Piteå paper mill produces 700,000t of kraftliner a year. The material is used as a sustainable alternative to plastic by various brands.

Smurfit Kappa Paper Europe chief operating officer Laurent Sellier said: “This investment builds on our commitment to help create a sustainable future by building a profitable business based on responsible principles.

“Sustainable innovation plays a vital role in ensuring that the communities surrounding our sites are part of our long-term vision.”

Last month, the packaging firm acquired an injection facility in San Antonio, Texas, US, to help enhance bag-in-box production.

In February, Smurfit Kappa expanded its operations with the opening of a folding carton plant in Tijuana, Mexico.
