Building the bioheat plant to improve yield and energy efficiency
Metsä Wood, part of the Finnish Metsä Group, manufactures Kerto LVL® products for wood construction in Lohja, Finland. The wood always comes from 100% traceable sources. Over 90% of wood used at the mill is certified. Kerto LVL offers a wide range of solutions to global challenges in the entire value chain – locally in sourcing and production, and internationally in construction.
At Metsä Wood, the resource-wise use of wood drives operations and development. The yield of the mill has risen steadily due to careful planning and technological innovations. Part of the resource-wise operations, the side streams of Kerto LVL production are targeted to the highest value uses: sawdust and wood chips are used in pulp production and the rest, such as bark and other smaller fractions, to produce renewable energy at the local bioheating plant for running the mill and producing Kerto LVL with 100% bioenergy.
The bioheating plant was built next to the Lohja mill to capture the full potential of the production side streams. The heat energy production exceeds the mill’s needs. This means that Kerto LVL is made with 100% renewable energy and the energy provides district heat to the surrounding town of Lohja which supports the town’s aim to become a low-carbon society. Building the bioheat plant was one of the main projects in the wider development programme for improving yield and energy efficiency.GO BACK TO GOOD PRACTICES
