The Project’s Achievements:
Investment
30 million euros.
CO2 emissions saved
113.000 tonnes CO2 per year.
Any other sustainable benefits
Provides 95% of heating needed by Heinola district residents.
Replacing fossil fuels with renewable bioenergy
Project description
Stora Enso is investing 30 million euros in the Heinola fluting mill to cut greenhouse gas emissions by over 90% (equivalent to 113,000 tonnes of CO2 annually) by replacing fossil fuels with renewable bioenergy. The investment will be completed during the autumn 2025 shutdown.
The Heinola fluting mill produces high-quality fluting, which is the intermediate cardboard needed for corrugated board, mainly for export. Most of its wood is obtained from private forest owners in the surrounding area.
The investment supports the company’s environmental goal to halve its operational greenhouse gas emissions by 2030. The Heinola fluting mill supplies 95% of Heinola’s district heating required by the residents. Our investment supports Heinola’s climate-positive goals.
The implemented solution
This investment modernises the bubbling fluidised bed (BFB) boiler, adjusting its operation to maximise biomass fuel use. Sumitomo will supply boiler pressure frame components, new blowers, and the bottom ash removal system.
The investment will also improve the fuel reception, supplied by Raumaster, conveyor systems and silo.
Once completed, our Nordic Semi-Chemical Fluting will have the lowest carbon footprint on the market.
Key Suppliers / Partners
Sumitomo provides the parts for the boiler pressure frame and is responsible for the new blowers and the bottom ash removal system.
Raumaster supplied the fuel handling equipment.
“The investment is one of the most significant in the mill’s history, aiming at sustainable development and efficient biofuel utilisation. Once achieved, it will be possible to replace the remaining fossil fuels used for the mill’s energy source with renewable bioenergy, reducing greenhouse gas emissions by over 90%.
This is my largest project and interesting to lead a project of this scale from procurement to implementation. The work is on schedule but there is still much to do. Equipment installations will begin in the spring and conclude during the autumn 2025 shutdown. Safety is the most important aspect and is upheld daily. Good collaboration among stakeholders is a prerequisite for a successful project.”
