The world's first next-generation bioproduct mill

​​Metsä Board's associated company Metsä Fibre is currently building the world's first next-generation bioproduct mill in Äänekoski, Finland. With a value of EUR 1.2 billion, this represents the Finnish forestry industry's largest ever investment.

Once completed, the mill will produce 1.3 million tonnes of pulp per year – nearly three times the annual production of the current pulp mill on this site. Metsä Board will invest EUR 24.9 million into the project, with the company's holding in Metsä Fibre remaining at 24.9 per cent. The mill will begin operations in the third quarter of 2017.

 The ​ Äänekoski bioproduct mill's figures speak for themselves. This is the next generation of pulp and energy production.

More than just a pulp mill

The bioproduct mill will use 6.5 million cubic metres of pulpwood per year to produce 1.3 million tonnes of softwood and birch pulp. Making full use of wood and production side streams was the starting point in designing the mill. Bioproducts will make up 20 per cent of the mill's net sales, even in the first phase.

The most efficient recovery boiler in the world

A significant share of all renewable energy produced in Finland is generated when black liquor, consisting of wood and cooking chemicals, is combusted in a recovery boiler in pulp production. This process converts the cooking chemicals into a reusable form. The bioproduct mill will be the most energy-efficient pulp mill in the world, as its equipment solutions are based on highly advanced energy technology. The mill will produce 2.4 times as much electricity as it uses.

The bioproduct mill's fibre line will process wood chips into pulp in around 24 hours. Production side streams will be used to produce other bioproducts and bioenergy. In terms of efficiency, the bioproduct mill will be in a class of its own.
