ANDRITZ starts up key production technologies for Metsä Group’s new bioproduct pulp mill in Finland

The core equipment supplied by ANDRITZ originates mainly from Finland, with a significant part being fabricated at the ANDRITZ workshop in Savonlinna. With the installation and smooth start-up of the equipment supplied, ANDRITZ once again demonstrated its outstanding technological capabilities. ANDRITZ supplied the following equipment to Metsä Group’s bioproduct pulp mill:

  • a wood processing plant, including three debarking and chipping lines, with the highest capacity in the world (pine/spruce/birch: 470/350/270 m3 solid-over-bark per hour);
  • a flexible softwood/hardwood fiberline with the highest softwood capacity in the world (3,900 tons per day);
  • the world’s most energy-efficient black liquor evaporation with the highest capacity in Europe (1,650 tons/hour);
  • the largest recausticizing plant in Europe (white liquor production of 16,000 m3/day).

With this major delivery, ANDRITZ is once more strengthening its position as one of the world’s leading suppliers of key equipment for pulp mills. “ANDRITZ is our long-term co-operation partner with whom we have developed our mills consistently. In the bioproduct mill project we have used an open-book project model, which has created good prerequisites for co-operation useful to both partners. The result is a world-class mill, which was built on time and on budget”, says Timo Merikallio, Project Director, from Metsä Group.
