European plant closures and major investments in India and Thailand reveal that sustainability credentials alone cannot guarantee the commercial survival of next-generation fibres.
The global market for lyocell and other lower-impact cellulosic fibres continues to expand, but a series of factory closures in Europe is exposing a difficult reality for sustainable textile manufacturing: innovation alone is not enough to keep production economically viable.
While brands increasingly promote renewable, biodegradable and resource-efficient materials, fibre manufacturers must still contend with energy prices, labour costs, plant utilisation, financing conditions and firm purchasing commitments from customers.
Recent developments involving Kelheim Fibres and Lenzing demonstrate that even technically advanced European facilities can struggle when production costs rise and buyers are unwilling to guarantee sufficient volumes. Meanwhile, new lyocell capacity is being developed closer to Asia’s major textile and apparel manufacturing centres.
Kelheim Fibres to Close German Production Site
German speciality viscose manufacturer Kelheim Fibres confirmed that it would terminate operations on 31 March 2026 after efforts to secure the company’s future failed.
The company had undergone internal restructuring after entering insolvency proceedings and had sharpened its focus on speciality fibres for hygiene, filtration and technical applications. It also reported continued support from a significant proportion of its customers.
However, the investor and sales process conducted under Germany’s self-administration framework did not produce a viable solution. A potential strategic investor withdrew at short notice, while confirmed customer orders remained below the level required to operate the plant economically.
Kelheim Fibres also cited the absence of orders from a key customer as an important factor in its closure decision. Following the completion of remaining production, the company began an orderly shutdown process and introduced measures to assist affected employees.
The closure is particularly significant because Kelheim was not producing an obsolete material. Its speciality viscose fibres served established markets in hygiene products, wipes, filtration systems and performance applications.
Its experience illustrates the difference between customer interest and bankable demand. Manufacturers may receive positive feedback from brands and converters, but factories require binding orders and predictable volumes to support continuous industrial production.
Lenzing Plans to Phase Out Two Historic Lyocell Plants
The pressure on European fibre manufacturing extends beyond Kelheim.
Lenzing Group announced in July 2026 that it plans to phase out fibre production at its Heiligenkreuz facility in Austria by the end of 2026 and at its Grimsby plant in the United Kingdom by the end of 2027.
The two facilities occupy an important place in the development of commercial lyocell. Grimsby is widely associated with the early industrialisation of the fibre that later became internationally recognised under the TENCEL brand.
Lenzing said it would evaluate strategic alternatives for both sites, including potential divestment or other solutions that could preserve value. If no viable alternative is found, the company intends to proceed with a structured closure while maintaining supply continuity for customers.
The decision forms part of a broader transformation designed to strengthen Lenzing’s core production network and improve the group’s long-term competitiveness. The company is also implementing efficiency measures at its Indonesian operations.
These developments do not indicate that demand for lyocell has disappeared. Instead, they suggest that the geography of competitive fibre production is changing.

Lenzing Expands Lyocell Production in Thailand
Only months before announcing its European restructuring, Lenzing expanded production of VEOCEL-branded lyocell fibres at its facility in Thailand.
The move introduced the company’s nonwoven-grade lyocell production to Asia for the first time. According to Lenzing, manufacturing in Thailand will place the fibres closer to regional nonwoven customers, shorten delivery times and improve supply-chain reliability.
The Thailand site already represents one of the company’s most important global lyocell production bases. Its location provides access to Asia’s extensive network of nonwoven, textile and hygiene-product manufacturers.
Rather than showing a retreat from lyocell, the simultaneous European closures and Asian expansion demonstrate a restructuring of production around scale, cost efficiency and proximity to customers.
India Makes Major Investment in New Lyocell Capacity
India is also emerging as an increasingly important centre for lyocell manufacturing.
In June 2026, Grasim Industries, part of Aditya Birla Group, announced an investment of ₹30.94 billion to develop the second phase of its lyocell project at Harihar in Karnataka.
The investment will add 110,000 tonnes of annual capacity through two production lines of 55,000 tonnes each. The first is expected to begin operations in 2028, followed by the second in 2030.
This new capacity will complement an initial 55,000-tonne lyocell plant currently under construction at the same site and scheduled to start production by mid-2027.
Once the announced projects are completed, Grasim expects its total lyocell capacity to reach approximately 210,000 tonnes annually, positioning it among the world’s largest producers of the fibre.
India offers several strategic advantages for this development. The country has a large textile manufacturing base, an expanding domestic consumer market, skilled industrial labour and close links to major apparel-exporting countries across South Asia.
These factors can provide new plants with access to both regional demand and international customers.
Sustainable Fibre Demand Does Not Automatically Guarantee Orders
Lyocell has become one of the textile industry’s best-known alternatives to conventional fibres because it combines performance with a potentially lower environmental impact.
Produced from dissolving wood pulp, lyocell commonly uses a solvent-spinning process designed to recover and reuse most of the solvent. The fibre offers softness, strength, moisture management and versatility across apparel, home textiles, hygiene products and technical applications.
However, growing market recognition does not guarantee that every production plant will remain profitable.
A fibre manufacturer must continuously cover substantial fixed costs, including:
- Energy and process heat
- Chemicals and raw materials
- Skilled labour
- Equipment maintenance
- Wastewater and emission management
- Environmental compliance
- Logistics and inventory
- Financing and depreciation
Older factories may also require significant investment to improve energy efficiency, increase automation or comply with tighter environmental requirements.
This creates a situation in which a fibre can succeed commercially while some factories producing it still close.
European Manufacturers Face a Structural Cost Challenge
Europe remains an important centre for fibre research, process engineering, certification and sustainable textile innovation. Nevertheless, its manufacturers are operating in an increasingly difficult industrial environment.
High energy and labour costs can make continuous fibre production considerably more expensive than in competing locations. Environmental requirements may also add capital and operating costs, even when those regulations ultimately improve production standards.
Asian manufacturing centres often benefit from newer large-scale facilities, integrated textile supply chains and shorter distances between fibre production, spinning, weaving, nonwoven conversion and garment manufacturing.
A lyocell plant located close to its customers can potentially reduce transportation costs, shorten lead times and respond more quickly to changes in demand. It may also achieve higher utilisation if it serves several large textile clusters within the same region.
The shift is therefore not simply about finding the lowest wages. It involves the complete industrial ecosystem surrounding the fibre.
Brands’ Purchasing Decisions Will Determine the Outcome
The latest closures also raise questions about the role of fashion brands, retailers and large converters in supporting sustainable material transitions.
Many companies have announced targets to increase their use of preferred, renewable or lower-impact fibres. However, fibre manufacturers require more than sustainability commitments expressed in corporate reports.
They need long-term purchasing agreements, realistic price acceptance and dependable demand.
When brands request sustainable innovation but continue choosing materials primarily on short-term price, the commercial risk remains with fibre producers. This is particularly problematic for innovative or speciality products that require dedicated production capacity and lengthy qualification processes.
Long-term offtake agreements could provide manufacturers with the confidence needed to invest in new equipment, maintain European facilities and scale emerging technologies. Without such commitments, technically successful materials may struggle to pass the next test: industrial survival.
What the Lyocell Shift Means for the Textile Industry
The changing geography of lyocell production offers several lessons for other sustainable textile materials, including recycled fibres, bio-based synthetics and next-generation cellulose technologies.
Successful laboratory development is only the first stage. New materials must also demonstrate:
- Reliable production at industrial scale
- Competitive and predictable pricing
- Consistent fibre quality
- Access to appropriate raw materials
- Efficient logistics
- Customer qualification
- Sufficient contracted demand
- Financing for commercial expansion
The industry frequently focuses on whether a new fibre can technically replace an established material. The more difficult question is whether it can be produced profitably and continuously at the price and volume required by the market.
Lyocell’s Future Remains Strong—but More Geographically Concentrated
The closure of European fibre plants should not be interpreted as evidence that lyocell has failed. Investments in Thailand and India indicate that producers still see substantial long-term demand for cellulosic fibres.
What is changing is the location and structure of production.
Future lyocell capacity is increasingly likely to be built near large textile-processing markets, where manufacturers can combine modern plants, economies of scale, competitive operating costs and direct access to customers.
Europe may retain a central role in technology development, premium applications, standards and specialised production. But without improvements in industrial competitiveness and stronger commitments from buyers, the region risks losing more of the manufacturing capacity needed to turn its sustainability ambitions into physical products.
The central lesson is clear: sustainable materials survive not only because they offer environmental advantages, but because somebody can manufacture them competitively—and because customers are prepared to purchase them at commercially viable volumes.
