Clean paper

Metso Paper (part of Metso Corporation) is rebuilding a pulp and paper mill of the Slovakian pulp and paper producer, Severoslovenske Celulozky a Papierne a.s. in Ruzomberok. The rebuild targets production increase and process improvements, which will enable the mill to lower its environmental impact. The modernisation will be completed by September 2004. Metso Paper's delivery will include the modernisation of the washing and screening systems, as well as of the oxygen delignification and bleaching processes. Metso Paper will also supply a complete bale dewiring line for the paper mill. The new equipment will preserve pulp quality and increase the mill's daily production capacity from the present 900 air-dry tonnes to 1,300 air-dry tonnes. The new oxygen delignification process will reduce both chemical consumption and costs, while also increasing the yield. The ozone stage, in turn, will lower the amount of chlorinated organic compounds (AOX) from the bleaching process, thus reducing the mill's environmental impact.
