SCA Announces Upgrade Projects at Two Swedish Mills

Dec. 17, 2009 - SCA said that it will invest SEK 500 million in a new lime kiln at the company's Ostrand pulp mill in Timra, Sweden.

The enviro/energy-related project will allow the mill to increase production by 10,000 tonnes of pulp per year and reduce its fossil-based CO2 emissions by 80%, SCA said.

The new lime kiln will replace two existing oil-fired lime kilns and will use fuel pellets from SCA's BioNorr plant in Harnosand.

Lime kilns play an important role in the production process at sulphate pulp mills, SCA explained. The process produces lime sludge, consisting primarily of calcium carbonate. The lime kiln converts this to calcium oxide (slaked lime), which is then reused in the pulp production process.

The Ostrand mill's two lime kilns consume approximately 17,000 cubic metres of oil per year and significant savings will be made when the oil is replaced with biofuel. The new lime kiln will also lead to lower chemical and maintenance costs, SCA said.

The new lime kiln is expected to start-up by the end of 2011.

The Ostrand mill produces 420,000 tonnes of chlorine-free bleached kraft pulp per year.

New Winder at Munksund Mill
SCA also announced that it will spend SEK 255 million on a new winder its Munksund mill outside Pitea, Sweden. The mill produces white top kraftliner.

The new winder will replace an existing winder and provide "somewhat increased production capacity," SCA said.

The new winder is expected to be in operation by spring 2011.
