UPM will start using pine for mechanical pulping at the Kajaani mill - New innovative method will disperse harmful pitch

(UPM, Helsinki, April 24, 2007 at 12.20) – UPM has developed a new innovative method for using pine for mechanical pulping. UPM has successfully completed several pilot trials during recent years at its Kajaani mill in Finland. UPM's partner in the pilot project has been the German company ITT Wedeco.

UPM will invest EUR 11 million to build a mill scale application of ozone treatment at the Kajaani mill. The objective is to diversify the mill's raw material base as well as to create cost savings without affecting paper quality and paper machine runnability.

The amount of pitch has traditionally restricted using pine for mechanical pulping. In the new method, the harmful pitch will be dispersed by using ozone.

The use of pine in production will start in Kajaani after the investment is completed in the early 2008. The project will be carried out in cooperation with UPM's R&D Center. The method can also be applied to other UPM paper mills using mechanical pulp after the mill scale testing period in Kajaani.
