Metsä Fibre, which is part of Metsä Group, has built a new bioproduct mill in Äänekoski in Central Finland. With a value of EUR 1.2 billion, the bioproduct mill is the largest investment in the history of the Finnish forest industry. It creates more than 2,500 jobs throughout the value chain in Finland, with 1,500 of them being new jobs.
The Äänekoski mill is the first next-generation bioproduct mill in the world. Its annual pulp production capacity is 1.3 million tonnes. In addition to high-quality pulp, it is producing a broad range of other bioproducts, such as tall oil, turpentine, bioelectricity and wood fuel.
Potential new products created from production side streams include for example textile fibres and lignin products. The mill is designed to allow for a broad, diverse range of products manufactured by a unique bioeconomy ecosystem of companies.
Metsä Group’s next-generation bioproduct mill in Äänekoski came into operation as planned on Tuesday, 15 August 2017 at 6:00 in the morning. Pulp deliveries from the new mill to customers will begin in early September 2017.
Why the bioproduct mill was built?
- The demand for softwood pulp is increasing steadily.
- The demand for softwood market pulp was around 24 million tonnes in 2014 and is expected to increase to around 26 million tonnes by 2025. Demand is growing most strongly in Asia, particularly in China.
- The price competitiveness of the mill is at a good level, as it is using northern softwood pulp.
The investment supports Metsä Fibre’s growth and improves long-term profitability by making use of the strong softwood pulp market and sustainably harvested felling surplus in Finland.
- The mill was constructed in the area of the previous Metsä Fibre pulp mill in Äänekoski in Central Finland. The new mill replaced part of the previous mill and serves the local forest industry. The previous pulp mill in Äänekoski was shut down and its dismantling is currently in progress.
- Its location is ideal in terms of availability of raw materials, and the necessary logistics networks are already in place.
- The bioproduct mill is creating a diverse ecosystem of bioeconomy companies that will develop and produce the bioproducts of the future from wood raw materials. This ecosystem will benefit not only the region, but also Finland.
Effects of the bioproduct mill
- The bioproduct mill is the largest investment in the history of the Finnish forest industry. It is expected to have an annual impact of more than EUR 0.5 billion on Finland’s income.
- The annual increase in the value of exports is EUR 0.5 billion.
- The bioproduct mill is diversifying the structure of the Finnish forest economy and bioeconomy and expands their product selection through high-added-value products.
- The overall effect on employment during the construction phase was more than 6,000 person-years.
- Its employment effect throughout the value chain in Finland will be 2,500 jobs, including 1,500 new jobs.
- The most significant employment effects are expected to be in the forest industry and transport.
- The bioproduct mill is helping Finland achieve its goals in terms of renewable energy. The mill is producing 2.4 times as much energy as it needs.
- The mill is increasing the share of renewable energy in Finland by more than two percentage points.
- Despite the increase in pulp production, the bioproduct mill is able to operate within the emission limits of the previous mill´s environmental permit.
- The bioproduct mill is significantly increasing the use of wood in Finland as a whole.
- The annual use of pulpwood is increasing by around 4 million cubic metres at the national level.
- The sustainable increase potential is 7 million cubic metres of softwood fibre and 4 million cubic metres of birch fibre. The wood is mainly purchased in Finland.
- Äänekoski’s central location and the broad member base of Metsäliitto Cooperative are ensuring a sufficient supply of wood. Pulpwood supply is supported by Metsä Group’s strong wood product industry, which uses logs as a raw material.

Significance of the bioproduct mill
Totalling EUR 1.2 billion, the investment in Metsä Group’s bioproduct mill is the largest in the history of the Finnish forest industry. Production at the mill is designed to be resource efficient. Annual pulp production in Äänekoski, which previously was totals around 0.5 million tonnes, is increasing to 1.3 million tonnes. The annual economic impact on Finland is estimated to be EUR 0.5 billion. The bioproduct mill is diversifying the structure of the Finnish forest economy and bioeconomy and expanding their product selection through high-added-value products.
The two most recent pulp mills in Finland were completed in Rauma in 1996 and in Joutseno in 2001, these mills are Metsä Fibre´s.
Totalling EUR 1.2 billion, the investment in Metsä Group’s bioproduct mill is the largest in the history of the Finnish forest industry.
The world’s first next-generation bioproduct mill concept allows for the integrated manufacture of new bioproducts, the resource-efficient use of side streams from the industrial process, and the creation of a new type of bioeconomy ecosystem. Despite the increase in pulp production, the mill is able to operate within the emission limits of the previous mill´s environmental permit. The environmental impact assessment (EIA) process has been used to assess and minimise the environmental effects of the project. The Regional State Administrative Agency for Western and Inland Finland has granted an environmental permit and a water intake permit for the bioproduct mill. These permits enabled the mill to begin operating.
The following environmental aspects were considered as early as the planning phase:
The mill is using 4.5 million cubic metres of softwood and 2 million cubic metres of birch per year. It is increasing the annual consumption of pulpwood in Finland by around 4 million cubic metres. Most of the increase consists of softwood pulpwood. The pulpwood is mainly be purchased in Finland.
The annual felling of softwood pulpwood can be increased sustainably by 7 million cubic metres in Finland, and that of birch pulpwood can be increased by 4 million cubic metres.
Sustainably managed forests serve as carbon sinks that help to mitigate climate change. The intention is to purchase most of the wood used by the mill in Finland. Ninety per cent of the wood used is certified wood.
Pulp bleaching at the bioproduct factory is based on ECF technology, a modern technology involving oxygen, hydrogen peroxide and chlorine dioxide as the bleaching chemicals. In a modern bioproduct mill, ECF bleaching based on chlorine dioxide can be made as water efficient as TCF bleaching, which involves no chlorine chemicals. Modern ECF and TCF bleaching methods do not differ from one another in terms of environmental effects.
Sodium sulphate is a neutral salt used in detergents, for example. The modern pulp mill has a closed chemical cycle, meaning that its environmental emissions are low. In a closed chemical cycle, the sodium and sulphuric chemicals used in various process phases increase the amount of chemicals that are recycled. The increase in sulphuric chemicals has traditionally been neutralised by removing sodium sulphate (Na2SO4) from the chemical cycle by dissolving it in wastewater in accordance with the environmental permit. This increases sodium and sulphur levels in the receiving waterway. Any environmental effects are dependent on the receiving waterway. The effects are small in a strongly flowing body of water, such as Lake Kuhnamo. The need to remove sodium sulphate can be affected through the selection of mill processes and process chemicals. The goal is to eliminate the need to dissolve sodium sulphate in wastewater during the normal operation of the modern bioproduct mill.
Natura 2000 area
The lake region of Vatianjärvi and Saraavesi is a protected Natura 2000 area in the lower reaches of the Äänekoski mill area. The protected area consists of several parts. Closest to the mill area, the Lujiankoski and Kapeenkoski rapids are around eight kilometres from the discharge point for treated wastewater. The starting points for the planning of the bioproduct mill include ensuring that its environmental load is not exceeding the limit values of the environmental permit, which was granted to the previous pulp mill in 2006. In other words, the mill is not affecting the state of the natural waterways in the Natura 2000 area located around eight kilometres from the mill.
Effects on flora and soil
The new bioproduct mill is located in the present industrial lot. The new mill do not have effects to air quality. Mill is not having any detrimental effects on the flora or soil inside or outside the mill area. Its effects on the flora and soil were evaluated as part of the environmental impact assessment (EIA).
Increased water usage
The pulp production capacity of the new bioproduct mill is almost three times more that of the previous pulp mill. The goal is for the new mill to have closed water cycles and an effective wastewater treatment process, and its total process water usage and effluent flow are around the same level as those of the previous pulp mill. The wastewater generated by the mill is not having an effect on water system classifications or the use of local natural water systems.
The bioproduct mill requires a larger volume of cooling water than that of the earlier Äänekoski mill area. At its highest, the total use of raw water in summer conditions are exceeding 7,000 litres per second. However, most of the water will be returned clean to the natural waterway, and the temperature of the waterway will increase by a few degrees in the discharge area.
Effect of temperatures on the natural waterway
The thermal load from the new bioproduct mill is several times that of the previous pulp mill, and the need for cooling water is increasing in relation to production. Normally, the thermal load is channelled into the natural waterway. At the bioproduct mill, however, the goal is to reduce waste heat by making use of the thermal load in the manufacturing processes of other bioproducts. Nevertheless, the thermal load channelled into Lake Kuhnamo is increasing compared to its previous level. The increase in the temperature of cooling water may delay the freezing of the lake or cause it to thaw earlier than usual.
The effects of the thermal load on Lake Kuhnamo and the rest of the natural waterway downstream of the bioproduct mill were modelled as part of the environmental impact assessment (EIA).
The bioproduct mill is delivering industrial symbioses to create an ecosystem that makes use of waste from the manufacture of the main products. The goal is for the bioproduct mill not to generate a significant amount of landfill waste. Achieving this goal will take several years after the first phase of the new bioproduct mill.
In all respects, the emissions generated by the new bioproduct mill are lower than the limit values determined by the proposed EU directive on the limitation of emissions of certain pollutants into the air from medium combustion plants. The equipment and processes used at the mill represent the best available technologies (BAT). Even though the capacity of the new bioproduct mill is more nearly triple that of the previous pulp mill, it is having a positive effect on the quality of air in Äänekoski, particularly in terms of odorous compounds. The spread of the emissions generated by the mill was modelled as part of the environmental impact assessment (EIA).
The capacity of the bioproduct mill is nearly triple that of the previous pulp mill. The traffic bringing wood and chemicals to the mill, as well as that taking the final products from the mill, are growing correspondingly. Raw wood is transported from the forest to the mill by lorries and trains. A total of 240 raw wood lorries and 70 flat wagons will be arriving at the mill each day, and 44 wagons of pulp is transported to the Vuosaari Harbour. The increase in traffic is generating more noise along the points of entry into the town of Äänekoski. The increase in noise levels was modelled as part of the environmental impact assessment (EIA). The increase in traffic is also increasing the safety risk posed by traffic. Metsä Fibre cooperates with the road authorities and the local authorities to improve road safety.
The amount of noise generated by the mill can be affected by placing the noisiest sections in a manner that enables their noise to subside before the border of the mill area. In addition, limit values are set for noise when acquiring equipment for the mill.
The increasing traffic is generating the most noise, including near residential areas. The noise generated by the mill and by the traffic were modelled as part of the environmental impact assessment (EIA).
- Its overall effect on employment during the construction phase was more than 6,000 person-years.
- Its employment effect throughout the value chain in Finland is 2,500 jobs.
- A total of 1,500 new jobs are created in the value chain.
- The employment effects are most significant in the forest industry and transportation.
- New opportunities are created for small and medium-sized enterprises in particular.
The bioproduct mill is a practical implementation of the targets of the Finnish Bioeconomy Strategy. The goal of the bioeconomy is a low-carbon, energy-efficient society based on the use of renewable natural resources and recyclable materials. Finland intends to lead the way in the bioeconomy while also enhancing its competitiveness and economic development, as well as the employment and well-being of its people.
The bioproduct mill concept allows for the integrated manufacture of new bioproducts, the resource-efficient use of the side streams of the industrial process, and the creation of a new type of bioeconomy ecosystem. The bioproduct mill is helping Finland achieve its renewable energy goals.
The mill is increasing the share of renewable energy in Finland by around two percentage points. The bioproduct mill is having an electricity self-sufficiency rate of 240 per cent.
Its business model is based on an efficient partner network in which new products are upgraded in cooperation with various players.
Around 50 per cent of the wood raw material used in pulp mills becomes pulp. At the bioproduct mill, 100 per cent of the wood raw material and side streams are used for products and bioenergy. Its business model is based on an efficient partner network in which new products are upgraded in cooperation with various players.
The global demand for softwood pulp is increasing steadily and will increase by around 2 million tonnes by 2025. Demand is growing most rapidly in Asia, particularly in China.
