Groundbreaking textile-to-textile recycling technology for true circularity.

Our patented technology takes piles of textile waste that would otherwise be landfilled or burned and transforms them into brand-new premium-quality fibers for the textile industry.

How it works.

We take in cotton-rich textile waste no longer fit for use and we clean it. It doesn’t matter what color the incoming textiles are, it doesn’t matter how worn out they are, it doesn’t even matter if there’s something synthetic like polyester or elastane in the mix, as long as about 88% of the total is cotton.
During the cleaning phase we remove synthetic fibers and dyes and capture what’s precious to us: the cellulose, a building block all aplants that is most abundant in cotton. We break the cellulose down at the molecular level, activate it with urea and dissolve it to create a liquid cellulose. The liquid cellulose is wet-spun into new fiber filament and cut to staple length, washed and dried.
And voilà, old textiles that were once destined to become pollution have instead become valuable, brand-new textile fibers that are ready to be made into new yarns, fabrics, and textiles. The scientific name of our unique textile fiber is cellulose carbamate fiber – but you can call it Infinna™.


Regenerated – and upgraded

Our technology creates a virgin-quality textile fiber 100% from textile waste. This makes it a consistently high-quality, circular alternative to conventional fibers like cotton, viscose, and polyester.

Blended textiles? No problem.

Our process loves cotton because it feeds on cellulose. But it can handle mixed color, blended post-consumer fabrics that contain materials like polyester and elastane.

Responsible chemistry

Our technology uses responsible, ZDHC and MRSL compliant chemistry. There’s no need for carbon disulfide (CS2).

1

Collection and sorting

Textile waste is collected and sorted by type. For us, the most valuable textiles have a high cotton content.

2

Disintegration

Non-fibrous materials like buttons, zippers and so on are removed, and the textiles are mechanically disintegrated to fine shreds.

3

Fiber separation

The cellulose is captured and separated from non-cellulosic particles like polyester and dyes.

4

Carbamation

The cellulose is activated with urea and a stable, dissolvable cellulose carbamate powder is born. Whether initially a T-shirt, cardboard or rice straw, the raw material turns into the same powder. From this point on material originating from the different feedstock types can be mixed.

5

Dissolving and wet-spinning

The cellulose powder is turned into a honey-like liquid and impurities are filtered out. New fiber filaments are born when the cellulose crystallizes during the wet spinning process.

6

Infinna™

The fiber filament is cut, washed and dried. The regenerated cellulose carbamate staple fiber – Infinna™ – is ready for the next phase in the textile manufacturing supply chain.

7

Delivery

The Infinna™ staple fibers are delivered to yarn spinners or nonwovens manufacturers to be made into products like clothing and home textiles, or wipes and diapers.

”Increasing the uptake of recycled fibers is a key strategy, with vast potential to reduce GHG emissions to mitigate climate change, prevent biodiversity loss, halt negative impacts on soil health, and reduce water consumption.”

Coming up: Commercial-scale Infinna™ Factory. And More.


Having produced Infinna™ at our two pilots in since 2018, we are now working to build the first commercial-scale Infinna™ factory in Kemi, Finland at the site of a discontinued paper mill. The factory, set to start commercial deliveries in 2026, will have a capacity of 30,000 metric tons of Infinna™ annually, which is equivalent to the fiber needed for about 100 million T-shirts.

With most of the future factory´s production capacity already sold out for several years ahead, and the demand for cotton-like recycled fibers by far exceeding the supply in the global market, we are accelerating the Infinna™ capacity build-up by actively advancing the next, larger-capacity Infinna™ factories in close partnerships. Through this model, we target an annual production capacity of 500 000 tons of Infinna™ by 2030.

Future-proofed business.

It’s coming – a future where recycled and regenerated textiles replace those made with new resources. Why? Because it’s what people and brands want, and it’s what the planet needs. As your partner, we help to future-proof your business through the unique benefits of our ready and proven technology.

New premium product

Enhance your existing product portfolio with Infinna™ – a unique, sustainable, and in-demand premium textile fiber that looks and feels like cotton and is as versatile.

All-in-one process

Our ready and proven technology covers all steps – from the pre-treatment of the raw material to the finished, ready-to-ship regenerated Infinna™ textile fiber with high demand.

Responsible chemistry

Our chemistry conforms to the ZDHC and MRSL and the whole process has been carefully designed to be safe, eliminate waste, and preserve resources.

Circular solution

Replace resource-heavy virgin raw materials that tax biodiversity with cellulose-rich feedstock that’s already in use, like old clothes. Keep biomass in circulation and leave the land for food crops and wilderness.

Endless flexibility

We make Infinna™ 100% from textile waste, but our robust technology can also be utilized to produce the same, high-quality fiber from a wide range of other cellulose-rich feedstock, such as used cardboard, paper, and wheat or rice straw, by amending the production set-up.

Made modular

Our technology is made up of 3 distinct modules that can be located at a single facility or at multiple sites. This opens up possibilities for various new-builds as well as retrofitting opportunities at e.g. existing pulp and viscose lines.

We’re in this together.

Decades of engineering, research and development have brought Infinited Fiber to where we are today: ready for our technology to help you meet the growing demand for high-quality regenerated textile fibers.

Real change will happen when we work together. That’s why we offer our partners a simple turnkey factory concept that enables fast access to a new market with limited investment. We offer our know-how, clear blueprints and access to top-notch engineering partners to enable the safe delivery and installation of our technology.
