New lime kiln at Östrand mill reduces carbon footprint by 80 percent

Dec 15 2011  A new lime kiln at SCA Östrand pulp mill, just north of Sundsvall, Sweden, reduces carbon footprint by 80 percent.

“The climate impact of Östrand pulp mill will be reduced by 80 percent at the same time as we are building a platform for continued growth. This is not only important for Östrand mill, but also for the entire SCA Group.”This was the comment from SCA’s CEO, Jan Johansson, when he on December 13, together with Västernorrland County Governor Bo Källstrand, inaugurated SCA’s 0.5 billion Kronor BioLoop 2011 investment at Östrand pulp mill. SCA has invested around 500 million Kronor in the Östrand mill’s BioLoop 2011 chemical recovery system. The largest portion of the investment comprises a new lime kiln, featuring a 125-meter-long rotating kiln, where lime mud from the pulp process is burned to produce lime, which is then reused in production. The new lime kiln is fuelled with wood pellets from SCA BioNorr in Härnösand and replaces two oil-fired lime kilns.The investment enables the Östrand pulp mill to increase production of chlorine-free bleached kraft pulp by 10,000 tons per year, while reducing emissions of fossil carbon dioxide from kraft pulp production by 80 percent.Östrand pulp plant produces 430,000 tons of chlorine-free bleached kraft pulp used in the production of publication papers and hygiene products, and 90,000 tons of chemical thermo mechanical pulp, CTMP, used in the production of hygiene products and packaging.
