From Pulp to Packaging: Metsä Group and Valmet Scale Up Moulded Fibre to Commercial Scale
The paper industry has spent years discussing the opportunity to replace plastic with fibre.
Now one of the more interesting technologies in that transition is moving from demonstration to commercial production.
Metsä Group has selected Valmet to supply what the companies describe as the first commercial-scale Valmet 3D Fibre production line, to be installed at Metsä Group's Äänekoski site in Finland.
The new line will manufacture three-dimensional moulded fibre products directly from pulp, with a nominal capacity of more than 100 million products per year. Start-up is currently scheduled for 2028.
For the paper industry, this is worth watching.
Because this isn't simply another packaging line.
It demonstrates how pulp and fibre producers could increasingly move further downstream—turning fibre directly into finished packaging products capable of competing with plastic.
From Making Paper to Engineering Fibre Products
Traditional papermaking generally follows a familiar value chain.
Fibre is prepared, formed into a continuous sheet, dried, wound and then converted into another product.
Moulded fibre changes that model.
Valmet says its 3D Fiber technology forms three-dimensional products directly from pulp, eliminating intermediate production stages. The commercial line at Äänekoski will sit alongside the demonstration plant where Metsä and Valmet have been developing the technology together.
That opens some interesting possibilities.
Instead of fibre competing only against other paper and board products, manufacturers can increasingly target applications historically dominated by thermoformed plastics and other rigid packaging materials.
Potential applications for moulded fibre extend across consumer goods, food packaging, industrial packaging and other formed products where brands are looking for renewable alternatives.
And if technologies like this scale successfully, the definition of a "paper company" could continue to change.
Why Commercial Scale Matters
There is an enormous difference between producing an innovative fibre product and manufacturing it economically at industrial scale.
Successful commercialisation requires much more than proving that the material works.
Manufacturers need:
- Reliable fibre preparation
- High production speeds
- Consistent forming
- Repeatable product quality
- Automation
- Efficient drying
- Low reject rates
- Competitive energy consumption
- Automated downstream handling and packing
That is why this project is particularly significant.
The proposed capacity of more than 100 million products annually moves moulded fibre away from being simply an interesting sustainability concept and towards genuine industrial manufacturing.
The next question will be economics.
Can fibre-based alternatives achieve the quality, productivity and cost required to compete with established plastic manufacturing technologies?
If they can, the addressable market for the forest-products industry becomes considerably larger.
A New Direction for Pulp Producers?
There is also a wider strategic point.
Historically, pulp producers have sold fibre into markets including paper, board, tissue and speciality products.
Technologies capable of transforming pulp directly into finished three-dimensional products create opportunities to capture more value further down the supply chain.
That could become increasingly attractive as producers search for growth markets beyond traditional paper grades.
It also demonstrates why innovation within the paper industry increasingly happens around the paper machine as well as on it.
Some of the most interesting growth opportunities over the next decade may come from completely new ways of using fibre.
The Workforce Behind the Technology
This transition also creates a different type of manufacturing environment.
A conventional paper mill relies heavily on papermaking expertise.
Advanced moulded-fibre manufacturing combines that knowledge with skills more commonly associated with automated manufacturing.
Future operations are likely to require expertise across:
- Fibre technology
- Process engineering
- Automation
- Robotics
- Machine vision
- Product development
- Quality engineering
- Maintenance and reliability
- Industrial data
- Packaging development
That creates interesting career opportunities for existing paper-industry professionals.
A Process Engineer who understands fibre behaviour, for example, could become extremely valuable when combined with automation or product-development experience.
Likewise, maintenance engineers accustomed to continuous-process manufacturing may find increasingly diverse career opportunities as fibre manufacturing expands into new product categories.
Recruitment Insight: The Paper Industry Is Competing for Different Talent
There is another important implication.
As fibre companies move further into advanced manufacturing, they won't only be competing with other paper mills for employees.
They will increasingly compete with packaging, automotive, food manufacturing, plastics, robotics and advanced manufacturing businesses for engineers and technical specialists.
That changes recruitment.
Paper companies will need to become better at explaining the scale and sophistication of modern fibre manufacturing to people outside the traditional industry.
The opportunity works both ways.
The industry needs to retain its deep knowledge of pulp and fibre while simultaneously attracting professionals with experience in automation, robotics, data and high-speed manufacturing.
The companies capable of combining those two talent pools could have a considerable advantage.
What Should Paper Professionals Take From This?
For people already working within pulp and paper, the message is positive.
Fibre expertise is becoming applicable to a wider range of products.
Professionals who combine traditional industry knowledge with newer capabilities in automation, digitalisation, sustainability and product development may find themselves particularly well positioned.
The future paper professional may not spend their entire career producing paper.
They may spend it engineering increasingly sophisticated products from fibre.
Final Thoughts
The Metsä Group and Valmet project is important not simply because another production line is being installed.
It represents something bigger.
The forest-products industry is looking beyond conventional paper and board applications and asking where else renewable fibre can compete.
If commercial-scale moulded fibre succeeds economically, it could create new markets, new factories and entirely new career paths across the industry.
And that makes this a development worth following closely.
