Andritz, Austria, has successfully started up key production technologies for Metsä Group’s new bioproduct pulp mill in Äänekoski, Finland. The new mill has an annual capacity of 1.3 million metric tons of pulp.

 

The core equipment supplied by Andritz originates mainly from Finland, with a significant part being fabricated at the Andritz workshop in Savonlinna.

Andritz supplied the following equipment to Metsä Group’s bioproduct pulp mill:

• Wood processing plant, including three debarking and chipping lines, with the highest capacity in the world (pine/spruce/birch: 470/350/270 cubic meters, solid-over-bark per hr.)
• Flexible softwood/hardwood fiberline with the highest softwood capacity in the world (3,900 metric tpd)
• World’s most energy-efficient black liquor evaporation with the highest capacity in Europe (1,650 metric tph)
• Largest recausticizing plant in Europe (white liquor production of 16,000 cubic meters per day).

"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", said Timo Merikallio, project director, Metsä Group.
