Modernising for the future: Metsä Board drives forward with major upgrades to Simpele mill

WestRock Company (NYSE: WRK) today announced it will permanently cease operating its paper mill in North Charleston, South Carolina, on August 31, 2023. The North Charleston mill produces containerboard, uncoated kraft paper (KraftPak®), and unbleached saturating kraft paper (DuraSorb®), with a combined annual capacity of 550,000 tons. Containerboard and uncoated kraft currently produced at the mill will be manufactured at other WestRock facilities. The Company intends to exit the unbleached saturating kraft paper business when the mill shutdown is completed.

Now that the company has replaced its two oil-fired lime kilns with a biofuel-fired lime kiln, SCA Containerboard can claim to be the first kraftliner manufacturer with fossil-free industrial processes. The new lime kiln, part of the chemical recycling process in pulp production, was commissioned at the end of November. The construction of a new lime kiln is part of the major investment in the Obbola Paper Mill, where SCA is expanding to increase kraftliner production and meet the company’s goal for fossil-free manufacturing. - The aim of our investment in a new lime kiln is to get rid of fossil oil, as well as to meet the need for expansion, says Pär Micael Samuelsson, project manager for the lime kiln subproject. - We will eliminate 8,000 cubic metres of oil per year. Had we continued to use the two oil-fired kilns, we would have needed an additional 2,000 cubic metres to achieve the necessary sulphate pulping. Now we don’t need this and we have completely eliminated oil consumption, he explains.

Consumers want products that enable them to lead more eco-friendly lives. This means minimising waste, carbon footprints and reducing the use of plastic. Stora Enso is responding to these needs with renewable packaging innovations, including formed fiber, a renewable and recyclable material that enables molding 3D shapes from wood fibers. “We are finding growth in sustainable and innovative packaging. To stay ahead of the curve, we are investing in next generation fiber molding technologies,” says Anna Jonhed, SVP Formed Fiber at Stora Enso. Recently Stora Enso became a shareholder of PulPac, a Swedish sustainable packaging technology company working to establish Dry Molded Fiber as the next global standard for sustainable packaging, replacing single-use plastics with circular fiber solutions.
