18 August 2017

International technology Group ANDRITZ has successfully completed start-up of the key production technologies for Metsä Group’s new bioproduct pulp mill with an annual capacity of 1.3 million tons of pulp in Äänekoski, Finland. All ANDRITZ processes were started up successfully according to the agreed schedules.

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.
