Stora Enso invests to improve energy efficiency and cost leadership at mills in Belgium and Germany

Group takes further steps to help to mitigate climate change

HELSINKI, Finland – Stora Enso (NYSE:SEO) today announced that it is improving energy efficiency through investments totalling EUR 260 million at Langerbrugge Mill in Belgium and Maxau Mill in Germany. Both projects are scheduled to be completed in the second quarter of 2010.

“These investment projects will significantly reduce fuel costs while increasing the use of bio energy at each mill. Through these investments, the Group will reduce its annual carbon dioxide emissions by some 105 000 tonnes. Langerbrugge Mill produces newsprint and uncoated magazine paper entirely from recovered paper and is located close to its customers. Production at Maxau Mill, which is also near its customers, thereby reducing its logistics costs, is based mainly on recovered paper,” says Juha Vanhainen, EVP Newsprint.

At Langerbrugge Mill and at Maxau Mill a new multifuel Circulating Fluidised Bed (CFB) boiler will be installed in the existing power plant. The aim of the investments is to enable combined heat and power generation with a competitive fuel mix. Once completed, these installations will increase the self-sufficiency in electricity of the two mills.
