Rauma sawmill

Sawmill and pulp mill work together seamlessly

The new Rauma sawmill is next to Metsä Fibre’s pulp mill. The integrated mill will make 100 per cent use of wood material. Wood chips from the sawmill are used to make pulp, while the pulp mill provides the sawmill with the heat and electricity it needs. In future, the integration of sawmill and pulp mill will enable completely fossil free production for both.

The sawmill investment also supports Metsä Fibre’s 2030 sustainability objectives: building the sawmill next to the pulp mill will enable both mills to operate entirely without fossil fuels in the future. Responsible logistics The location of the integrated mill, just three kilometres from the port of Rauma, means smooth logistics of sawn timber to customers by sea. The sawmill does not have its own warehouses. The finished sawn timber is transported directly from the sawmill to the port in packages. Euroports Finland is responsible for the sawn timber operation at the port. The sawmill and the pulp mill will also cooperate in road transport of wood and finished products. “The equipment used represents state-of-the-art technology. More end products will be transported in each load to customers. Larger loads re- duce the number of trips required, which is good for the environment,” says Haapaniemi.

The Rauma sawmill is integrated with Metsä Fibre’s pulp mill on the same site. The synergies of the integration will be exploited not only in ener- gy production and sidestream use, but also in logistics and services pro- cured from partners. Metsä Fibre produces sawn timber and pulp from softwood at the Rau- ma integrated mill. The side streams from production include bioenergy, tall oil, turpentine, bark, wood chips and sawdust. A fossil-free future Thanks to integrated operation, the new sawmill does not need its own power plant. “The sawmill’s by-products are transported by conveyors to the pulp mill, which uses the wood chips from the sawmill for pulp production. The bark and sawdust are used to produce bioenergy. The sawmill uses the electrical and thermal energy generated in the pulp mill’s production process,” Project Director Harri Haapaniemi explains.

“Our mills form an efficient integrated unit that will support the transition to fossil-free production.”
