Demand for fresh fibres paper board is constantly increasing. Metsä Board has therefore heavily invested in three of its mills in Finland to step up their overall production capacity to 150,000 tpa. The reconstruction of Metsä Board Simpele was completed in June 2011, that of the Kyro mill in November 2011 and the one of Ӓänekoski in May 2012. Resulting in a 20% increase in the production capacity equalling the average production of a paper borad machine in Europe.

In addition, the investment made in 2011 on the Kemi mill specializing in coated liners was a success. Today Metsä Board can rely, with its board production sites (including the plant in Kemi) on a production capacity of 1.31 million tpa.

However, Pasi Piiparinen recently appointed SVP, Head of Paperboard at Metsä Board considers that "what matters is not only to increase the capacity." Hence, "for future developments," he emphasises, "we will continue to invest in energy efficiency, by reducing our CO2 emissions and by reducing the use of fossil resources. We are investing in a new biomass boiler on the Kyro plant of the Hämeenkyrö site in Finland, which will use discarded wood for energy."
