All parts of the wood are utilised in the production of renewable raw materials. Wood is converted into sawn timber, pulp, energy, heat, biofuels, biochemicals and turpentine. All materials are utilised multiple times within UPM’s pulp mill. For example, chemicals used in the process are purified and repeatedly recovered for reuse.

The recovery boiler built at UPM Jakobstad in 2004 was the largest in the world at the time of its completion. The boiler is used to combust chemical by‑products generated in the pulp production process.

At the same time, combustion in the recovery boiler generates electricity, part of which is used for the mill’s own operations. UPM Jakobstad produces more electricity than it consumes, and the surplus is sold to the national electricity grid via Fingrid. Of all energy produced, 99.6 % is renewable (2025).

Water used in the production process is circulated several times. The Jakobstad pulp mill abstracts its water from Lake Luodonjärvi. After treatment in mechanical and biological wastewater treatment plants, the water is returned to the sea. The biological treatment stage takes place in basins containing beneficial bacteria and microorganisms that purify the water. Wastewater discharges are monitored and assessed regularly through both internal controls and inspections by authorities. On average, approximately 80 % of the water used in pulp production is returned to water bodies.

Alholmens Kraft produces process steam that is supplied to UPM for use in its production processes. This steam is an essential prerequisite for pulp production operations.

At the same time, the energy system is bidirectional: surplus steam and thermal energy generated in UPM’s processes can be fed back to Alholmens Kraft, where it is integrated into the overall energy production system. In this way, steam and heat circulate between the parties and form an industrial symbiosis in which energy efficiency is improved and surplus energy is utilised as efficiently as possible.

Walki and Billerud are also part of this system. Their production facilities are connected to the same district heating structure, and they purchase district heating via UPM from the heat produced by Alholmens Kraft.

District heating produced by Alholmens Kraft is fed into the district heating network owned by Herrfors, which is responsible for the distribution of district heating in the City of Jakobstad. Herrfors’ district heating network further supplies heat to residential buildings, properties and other typical end‑user destinations, such as public buildings and service facilities.

When logs are sawn into planks and boards, side streams such as bark, sawdust and wood chips are generated. The sawdust and wood chips are mainly directed to pulp production as raw material, while the bark is utilised for energy production within the forest industry integration. The bark is used as a biofuel for energy generation, and in addition, part of the bark is used for landscaping purposes.

Recycled wood and other wood‑based side streams generated in NCE’s operations are utilised in energy production at Alholmens Kraft. These side streams are delivered to Alholmens Kraft, where they are used as fuel for energy generation.

In addition, the paper and packaging materials industry generates other side streams suitable for energy use. Fibre sludge generated in Billerud’s processes contains wood fibres and can, after treatment or through co‑firing, be utilised in energy production. Edge trim generated in Walki’s production mainly consists of fibre‑ and wood‑based materials, which are well suited for use as an energy fraction, particularly when material recycling is not appropriate.

Sawdust and wood chips generated in sawmill operations are primarily used as raw material for pulp production.

Recycled wood and other wood‑based side streams generated in OSTP’s operations are utilised in energy production at Alholmens Kraft. These side streams are delivered to Alholmens Kraft, where they are used as fuel for energy generation.

In pulp production, not a single piece goes to waste. Bark and forest residues such as branches and stumps are used in energy production at Alholmens Kraft. The majority of the wood‑based fuel used by Alholmens Kraft consists of logging residues from regional forests. Small‑diameter wood, tree tops and branches are baled into bundles in the forest and crushed at the power plant using large, slow‑speed shredders. Stumps are crushed either at the power plant or at an earlier stage in the supply chain. The fuel mix also includes roundwood that is not suitable for pulp production.

Pulp production also generates other wood‑based side streams that are not suitable for pulp manufacturing or are rejected during the production process. These side streams are likewise converted into energy.

Wood‑based side streams supplied by UPM make up the largest share of Alholmens Kraft’s renewable fuel base.

Alholmens Kraft is the world’s largest biofuel‑fired power plant and produces electricity for both industry and consumers.

AK produces electricity for its owners (Herrfors, UPM‑Kymmene and Pohjolan Voima), who either use the energy themselves or sell it onwards to end users. AK generates electricity in an environmentally friendly and cost‑efficient manner, while taking the principles of sustainable development into account. The objective is to keep the share of biofuels as high as possible. The electricity produced by the power plant competes on the open Nordic electricity market. The more competitive the plant is, the greater the use of biofuels becomes.

UPM’s Jakobstad mills supply bark from pulpwood and saw logs and are the largest single supplier.

Most of the other wood‑based fuels consist of logging residues from forests in the region. Branches and tops are baled into bundles in the forest and crushed at the power plant site using heavy, slow‑speed crushers. Stumps are crushed either at the power plant or earlier in the supply chain. Roundwood that is not suitable for pulp production is also used as part of the fuel mix. In 2024, AK used 944 GWh of biofuels. This represents a decrease compared to 2023, when biofuel use amounted to 1,031 GWh.

The use of energy waste fuels and recycled wood is prioritised at the power plant, and their share of the fuel used at AK2 was 4.6 % during the year. Some of the recycled wood used originates from industrial facilities within the AIP area, supporting regional material utilisation.

The share of peat decreases year by year and accounted for 15.4 % of total fuel use in 2024. Peat still plays a role in ensuring security of supply, as relatively large amounts of fuel can be delivered at short notice when energy demand is high. At the AK plant, coal is mainly used as a support fuel to safeguard production during disturbances or disruptions in fuel logistics. In 2024, coal accounted for less than 3 % of AK’s total fuel consumption.

Both Alholmens Kraft and UPM‑Kymmene also sell electricity to the national power grid.

Within the forest industry integration at AIP, the connection between UPM and Alholmens Kraft (AK) forms the core of an industrial symbiosis in which material flows and energy production are closely interlinked. At UPM’s Jakobstad pulp mill, by‑products from the pulp production process are utilised in the recovery boiler, where energy and electricity are generated as part of the production process. This electricity is a key component of the forest industry integration’s internal energy system.

Alholmens Kraft is an integral part of the forest industry integration and the world’s largest biofuel‑fired power plant. AK produces electricity for both industrial use and consumers and supplies energy to its owners—Herrfors, UPM‑Kymmene and Pohjolan Voima—who either use the electricity in their own operations or sell it onward to the electricity market. AK’s objective is to produce electricity in an environmentally friendly and cost‑efficient manner, in line with the principles of sustainable development, while keeping the share of biofuels as high as possible.

UPM also plays a significant role in this system as a fuel supplier. UPM’s Jakobstad mills supply AK with bark from pulpwood and saw logs, making UPM the power plant’s largest single biofuel supplier. In addition, the wood‑based fuels used by AK mainly consist of logging residues from regional forests as well as wood that is not suitable for pulp production. In this way, internal and regional side streams within the forest industry integration are efficiently utilised for energy production.
