Botnia Äänekoski mill was built 25 years ago. During these years the mill has produced over 10 million tonnes of pulp. Of this amount, one half is softwood pulp and the other half birch pulp. The pulp grades are designed to meet our customers' needs. Äänekoski mill's customers are producers of paper and board. Today, the production of birch pulp amounts to approximately 80 percent. The annual capacity of the mill is 500 000 tonnes. The 25-years-old mill is clean, efficient and in very good condition. There have been various investments made into the mill during its life cycle. Thanks to the systematical and high-quality preventive maintenance, usability of the mill is at excellent level. This year, the investments will focus on improving the runnability of the digestor. Also, the electrostatic precipitator of the recovery boiler will be repaired. At Äänekoski mill there are two hundred multi-skilled employees. The official anniversary was on April 14.
