Metsä Group Äänekoski - Key technology for Bioproduct mill
Metsä Group's bioproduct mill in Äänekoski was started up on August 15, 2017. Valmet’s delivery to the mill included a recovery boiler, pulp drying line, gasification plant, lime kiln, sulfuric acid plant, and mill-wide Valmet DNA automation system. The bioproduct mill takes pulp production to a new level. In the mill, every single bit of the wood raw material and production side streams are utilized to achieve maximum material and energy efficiency.
The old pulp mill had started production in 1985 and was therefore approaching the end of its operating life cycle. Metsä Group
The new Äänekoski mill is called a bioproduct mill since it is increasing the product portfolio with new bioproducts, generating excess bioenergy, and using no fossil fuels.

The project was a success with the bioproduct mill coming into operation on 15 August 2017 - 7 minutes before the original plan. The mill reached its nominal capacity in August 2018.
