(News from RISI) Metsä Tissue is ramping up two new investment projects at its 81,000tpy Katrinefors tissue mill in Mariestad in central Sweden – a new tissue converting line for making toilet and household paper and a combined heat and power (CHP) plant.

The Futura-supplied Euro 10 million converting line has a capacity of some 25,000tpy and will raise the factory’s total converting capacity to around 80,000tpy.

The CHP plant is owned by Katrinefors Kraftvärme AB (KKAB), a 50/50 joint venture company owned by Metsä Tissue and the municipal energy company VänerEnergi.

KKAB started the commissioning process of the new plant in mid-September and the plan is to finish all the test runs and fine tuning by the end of the year, according to Mark Watkins, senior vice president of tissue in the Nordic and Baltic region at Metsä Tissue.

The Euro 30 million CHP plant will produce electricity and heat for the Katrinefors mill, as well as energy for the surrounding community in the form of district heating and grid electricity.

The plant has a heat capacity of 28 MWt and an electrical capacity of 7 MWe.

It will run on energy wood, including wood chips and forest residues sourced locally, and the tissue mill’s recycled fiber residues.

KKAB already operates one CHP plant at the factory, using the same raw materials.

The plant has a capacity of 37 MWt and 9.5 MWe. The new plant will increase the usage of wood for energy by 85 GWh/yr to some 280 GWh/yr.
