The Ghost Mills Are Stirring – How Finland Is Retooling Its Industrial Giants for the Bioeconomy

Finland’s paper industry is dying. Or so the headline says. But beneath the crisis – falling demand, mill closures, thousands of layoffs – a quieter transformation is underway. The same machines that once churned out newsprint are being rebuilt to produce packaging board, bio‑composites, lignin‑based chemicals, and carbon‑negative materials. The ghost mills are not being abandoned. They are being retooled.

Part I – The Crisis That Wasn’t a Surprise

In 2025, the Finnish forest industry entered a cyclical downturn that exposed decades‑old structural vulnerabilities. Industrial roundwood purchases fell roughly 20% year‑on‑year. Pulpwood prices dropped by up to 39% over eight months. Sawn timber production fell 20% in early 2026, dragged down by weak demand and weather disruptions. Total forest industry exports in 2025 still stood at a substantial €12 billion, but the sector was clearly navigating a correction after overheated markets.

The pulp market remained soft, with producers curtailing output and delaying investments in new capacity. Logistics challenges – rising fuel costs, disrupted global shipping routes – added to the pressure, squeezing margins across the value chain. At the same time, environmental regulation was becoming a defining force. A new government proposal would restrict logging during birds’ nesting seasons, introducing legally binding biodiversity protections that could tighten timber supply for months at a time.

Part II – The Paper Machine Collapse

The paper industry suffered the sharpest blows. Major producers closed capacity across the country. UPM and Sappi announced the closure of paper machines in Lappeenranta and Lohja, reducing Finland’s total paper capacity by approximately 11%. Sappi’s Kirkniemi mill shut down Paper Machine 2 entirely, cutting 175,000 tonnes of annual coated mechanical paper production and eliminating 93 positions. The Natural Resources Institute (Luke) forecast that paper production and exports would decline a further 3% in 2025 and more in 2026.

The machinery builders felt the cascade. Valmet, the global leader in paper and board machine technology, was forced into repeated rounds of change negotiations. In December 2025, the company completed negotiations covering over 950 employees, retaining the option for temporary layoffs across its Packaging and Paper business unit and Global Supply unit, concentrated in Jyväskylä, Vantaa, and Raisio. Just five months later, in April 2026, Valmet announced another round of change negotiations covering approximately 2,400 employees, citing “customer‑driven project delays, continued weak demand in paper and board machine markets, and softness in biomaterials services markets”. The measures were temporary – less than 90 days of layoffs – but the signal was unmistakable: the industry that built modern Finland was contracting.

Part III – Pulp Overcapacity and the Spectre of Mill Closures

By early 2026, experts warned that Finland’s forest industry could be forced to reduce capacity again, as rising raw material costs and weaker market conditions weighed on profitability. Juha Varis, senior portfolio manager at S‑Bank, told the Talousaamu programme that overcapacity in the European forest industry was evident across several segments – pulp, paper, packaging – and that investors expected some reduction in capacity.

The warning intensified after Björn Wahlroos, the veteran financier, said in the Asiastudio podcast that a large, modern pulp mill in Finland could be forced to shut down due to a lack of raw material. UPM CEO Massimo Reynal gave a stark assessment: “If the situation continues in the same way going forward, it becomes increasingly difficult to imagine that mill closures would not occur. This is not a matter of opinion, but a fact”.

The structural pressure is uneven. Older pulp mills and facilities in Eastern Finland face the most significant wood supply challenges. By contrast, large investments in new plants – including Metsä Group’s €2.2 billion pulp mill in Kemi, which started operations in autumn 2023 – represent a bet on the future, not the past. The industry is not collapsing. It is polarising.

Part IV – The Retooling: Converting Paper Machines to Packaging Board

The most visible evidence of transformation is the conversion of idle paper machines. Stora Enso’s Oulu mill undertook the most dramatic retooling. Following a €1.1 billion investment, the mill converted former paper machines into state‑of‑the‑art consumer packaging board lines. The new line, with an annual capacity of 750,000 tonnes, produces folding box board (FBB) and coated unbleached kraft (CUK). The environmental impact was immediate: carbon dioxide emissions were slashed by 90%.

The technology was supplied by Voith, the German machine builder, which converted what was once a fine‑paper production line into Europe’s largest board machine. At Stora Enso’s Varkaus mill, Valmet performed a similar conversion, turning an existing paper machine into a linerboard line to meet growing demand for renewable packaging.

This is not nostalgia. It is pragmatic industrial policy. A paper machine that printed newsprint for a declining market is now producing packaging board for a growing one. The core technology – large‑scale, high‑speed, continuous web processing – is adaptable. The product mix is not.

Part V – Beyond Paper: Lignin, Biocomposites, and Circular Chemicals

The retooling is not limited to paper machines. The entire forest industry is repositioning as a biorefinery sector, extracting value from every part of the tree.

In February 2026, Metsä Group and ANDRITZ started up a new demonstration plant for lignin refining at Metsä’s Äänekoski bioproduct mill. Lignin – the substance that binds wood fibres together – has traditionally been burned as bioenergy. The new plant converts it into bio‑based plasticisers for concrete and gypsum, replacing fossil‑based chemicals. Dow, the material science giant, is collaborating on the project. If the demonstration succeeds, a full‑scale production plant will follow.

The circular economy is also generating entirely new product categories. Researchers at the University of Oulu developed a method to turn green liquor sludge – the last unused waste fraction from pulp mills, generated in over 100,000 tonnes annually – into a recycled chemical that mines can use in ore enrichment. The method is already patented. Forestry giants including Metsä Group, Stora Enso, and UPM‑Kymmene are partners, alongside mining companies Boliden Kevitsa and Sotkamo Silver.

Valmet is exploring whether paper machines can produce pulp‑based biocomposites, turning forest biomass into high‑value materials beyond traditional paper grades. Aalto University and VTT’s FinnCERES competence centre is focused on developing new wood‑based materials for the bioeconomy. The WoodPro project, a Swedish‑Finnish collaboration, is valorising forest residues into 2,3‑butanediol, biopolymers, and hydrochar – high‑value products that close nutrient loops and stimulate rural development.

Part VI – The Bioeconomy Strategy: €30 Billion of Public Money

None of this is happening by accident. In January 2026, the Finnish government unveiled a €30 billion upgrade to its Bioeconomy Strategy 2035, to be deployed from 2026 to 2030. The funding is targeted at three core areas: wood biorefining, biodegradable materials, and bioenergy. The goal is to raise bioeconomy output from €64 billion in 2023 to €93 billion by 2030 – a 45% increase.

The strategy includes 50 new bioeconomy pilot platforms, support for synthetic biology and digital twin technologies, and incentives for private investment through green bonds and carbon credit subsidies. The target is to raise private investment share from 45% to 60% by 2030. Six regional bioeconomy parks are planned, expected to directly create 12,000 jobs and, with multiplier effects, over 30,000 new positions. Already, a bio‑based press roll cover from Valmet that replaces fossil materials with bio‑based alternatives has received ISCC PLUS certification, signalling that the market is ready.

Part VII – Where Are the Workers? The Labour Contradiction

For all the investment, one problem remains unsolved. An acute shortage of skilled workers threatens the future of the Finnish forestry sector. According to a 2025 report, the sector needs to recruit up to 1,000 new workers annually just to compensate for retirements and other attrition. The same report concluded that Finland needs to recruit more workers from abroad to ensure the sector’s survival.

This is where the dual economy contradiction bites hardest. Finland is simultaneously spending €30 billion to retool its forest industries for a bioeconomy future, while tightening immigration rules – raising permanent residency requirements from four to six years, adding work history and language tests, and setting income thresholds that block family reunification for middle‑skilled workers. The forest industry is not a software startup. It needs machine operators, chemical engineers, logistics coordinators, and forestry technicians – precisely the skills that Finland’s restrictive immigration policy makes hardest to import.

Part VIII – The Immigrant Engineer in Jyväskylä

Consider a specific, recurring scenario. A young mechanical engineer from Vietnam graduates from a Finnish university of applied sciences with a specialisation in paper machine technology. They speak intermediate Finnish, have completed an internship at Valmet’s Jyväskylä foundry, and are exactly the kind of skilled worker the forest industry needs to maintain and operate its retooled machinery.

Under Finland’s current rules, this engineer faces a work‑based residence permit with a €1,600 monthly income threshold. They will likely meet it. But then they face a six‑year wait for permanent residency, during which any interaction with police or security guards – a minor public order fine, a misunderstanding at a train station – can trigger deportation proceedings, because the Criminal Code’s possession of a dangerous object clause carries a maximum penalty of two years. A folding knife in a backpack, intended for a camping trip, becomes a deportation trigger.

The same engineer could move to Sweden, where the forestry sector is also transforming, where the path to permanent residency is shorter and clearer, and where the labour market integration of foreign‑trained professionals is actively supported. Sweden’s forest industry federation has welcomed the EU’s growth‑oriented bioeconomy strategy. It is not making the same mistakes.

Finland is spending €30 billion on machines and zero on the people who will run them.

Part IX – What Finland Stands to Gain

The transformation already underway is measurable. Stora Enso’s Oulu conversion slashed emissions by 90% and created a flagship facility for renewable packaging. Metsä Group’s Äänekoski biorefinery is turning lignin – once just fuel – into a value‑added chemical input for global construction. The University of Oulu’s green liquor sludge process turns a landfill liability into a mining chemical. The WoodPro project demonstrates that forest residues can be upgraded into biopolymers that replace fossil‑based plastics.

The next phase – lignin‑based carbon fibres, nanocellulose composites, synthetic biology‑enabled biochemicals – is already in university labs. Aalto University’s FinnCERES research programme has spent eight years developing the foundational science for a post‑fossil forest industry. The KELMI project in Eastern Finland is developing high‑value‑added solutions for the forest‑based bioeconomy, focusing on side streams that were previously burned or landfilled.

But none of this scales without people. The Finnish forest industry is not dying. It is being reborn. And rebirth requires labour – skilled, mobile, internationally sourced labour. The machines are ready. The research is ready. The policy is not.

Part X – Conclusion: Retool the Policy, Not Just the Plants

Finland has done the hard part. It identified the crisis early. It invested public money at scale. It retooled its industrial base. It built a bioeconomy strategy that is the envy of Europe. The ghost mills are stirring. Paper machines that once printed oblivion now produce packaging that replaces plastic. Lignin that was once smoke is now concrete additive. Waste sludge that was once landfill is now mining chemical.

But a mill that cannot find a machine operator is a monument, not a factory. A bioeconomy that cannot attract the engineers, technicians, and logistics specialists it needs will stagnate. Finland can spend €30 billion on plants, but if it continues to spend zero on making those plants legally accessible to the skilled workers who must run them, the transformation will fail at the loading dock.

The dual economy traps workers in coffee shops. The retooled forest industry offers an escape: high‑skill, high‑wage, high‑value employment anchored in place. But the escape route requires a visa. Finland can either issue that visa – to the Vietnamese engineer, the Indian chemical technologist, the Kenyan forestry technician – or it can watch Sweden, Germany, and Canada issue them instead.

The machines are ready. The question is whether the policy class is.
