UPM has claimed to have developed a new method for using pine for mechanical pulping.
The company said it has successfully completed pilot trials at its Kajaani mill in Finland.
UPM will invest EUR11 million to build a mill scale application of ozone treatment at the Kajaani mill with the objective of diversifying the mill's raw material base, as well as creating cost savings without affecting paper quality and paper machine runability.
The amount of pitch has traditionally restricted using pine for mechanical pulping, said the company but with 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 early 2008.
The method can also be applied to other UPM paper mills using mechanical pulp after the mill scale testing period in Kajaani.
The project will be carried out in cooperation with UPM's research and development centre.
UPM's partner in the pilot project has been the German company ITT Wedeco.
