Billerud (Sweden) will invest SEK 176 million in the no. 4 paper machine at its Gruvon mill. This investment is a combination of maintenance and quality and capacity upgrades and mainly comprises a new wet end and control system. The new installation will enable the machine to produce two-layer paper. Capacity will increase from the present 85,000 tonnes to over 100,000 tonnes. As a result of this investment, the product programme on the machine will mainly focus on low-grammage white liner and high-quality kraft paper. Therefore, in the long term Gruvon will only produce white paper products. The rebuilding is planned to be completed by autumn 2002. Billerud’s production of unbleached kraft and sack paper will be concentrated to Skarblacka.
