Stora Enso has invested EUR 1.1 billion in the now inaugurated production line together with other developments on the site area, amounting to a total of approximately 1.7 billion investment in the entire Oulu mill in 2019–2025. The investments have made it possible to convert former paper machines into board lines utilising the latest technology, while the environmental impact has been reduced by cutting fossil carbon dioxide emissions by 90%. The mill produces folding boxboard, kraftliners, paper bag material, and unbleached softwood pulp. Board materials are suitable for direct contact with food. Almost all of the Oulu mill’s production is exported.
“The Oulu production site is a strategically significant investment as it strengthens our leading position in high added value renewable packaging materials and increases Finland’s export revenue significantly. Consumer packaging made from wood fibers has great potential to replace plastic packaging and our materials are designed for existing recycling streams. The nearly carbon-neutral production site in Oulu is a prime example of an investment in bioeconomy, and it concretely contributes to the transition from fossil materials to renewable and recyclable packaging,” says Hans Sohlström, Stora Enso’s President and CEO.
The Oulu mill’s new production line utilises Stora Enso’s patented FiberLight Tec™ fiber processing technology. Technology enables the production of lighter, yet robust and durable boards. End products include, for example, different cardboard packaging for frozen, cold and dry food products, medicines, and beverage multipacks.
“Our folding box board can be up to a third lighter than traditional boards, the material is efficient and durable and helps our customers to reduce the consumption of packaging material and at the same time reduce their transport emissions. This means also that they have very high added value. Our mill’s location next to the deep port enables efficient logistics worldwide throughout the year. It is important for us to be involved in mitigating climate change,” says Matti Lielahti, Head of Stora Enso Oulu Business Unit.
“We mainly use pulpwood purchased from private forest owners in Finland, small-diameter wood, and wood chips from our sawmills for board production. We also utilise bark and sawdust for energy production. The bioenergy produced in the mill is used for district heating in Oulu,” continues Matti Lielahti.
