Metsä Group and Sweco, a specialist in the built environment and industry, have signed an agreement for the implementation planning of the new Kerto LVL mill in Äänekoski, Finland.

“We have strong confidence in Sweco’s expertise and resources from our previous collaboration projects. It is therefore natural that we continue our cooperation in this project to develop the Äänekoski mill area,” said Jaakko Anttila, executive vice-president at Metsä Wood.

Sweco is responsible for the complete implementation planning of the mill project, including structural, process and plant design. Sweco was also responsible for the design of Metsä Group’s Äänekoski bioproduct mill, which started operations in 2017, and the planned wood product mill will apply the synergy benefits offered by the mill area.

“For example, the steam needed in the production process of Kerto LVL will be produced at the Äänekoski bioproduct mill, and the condensate generated in the process will be utilised for heating the building,” said Tuulamari Helaja, business unit director, Industry and Energy at Sweco Finland.

“It is great to be involved in designing a resource-efficient production plant whose material-efficient wood products store carbon and reduce the carbon footprint of construction.”

Construction of the Kerto LVL mill in Äänekoski has progressed according to plan. Land construction works and the main frame installations are currently underway in the area.

The mill will have an annual production capacity of around 160,000m3 of Kerto LVL and is expected to start production in H2 2026. When completed, the mill will employ around 150 people directly and 200 people in its value chain, according to Metsä Group.
