Lyocell (Tencel)
Closed-loop wood-pulp fiber with 99% solvent recovery, silky drape, biodegradable.
What it is
Lyocell is a regenerated cellulose fiber made from wood pulp (usually eucalyptus or beech). The Tencel-branded process uses a non-toxic solvent (NMMO) recovered in a closed loop with ~99% efficiency.
Why it matters
Conventional viscose/rayon production is linked to deforestation and toxic chemical discharge. Lyocell uses FSC-certified pulp, recovers solvent, and produces a fully biodegradable fiber.
Upsides
- Closed-loop manufacturing recovers solvent and water
- Fully biodegradable and compostable
- Soft, moisture-wicking, naturally wrinkle-resistant
Trade-offs
- Energy-intensive pulping; check renewable-energy sourcing
- Generic 'lyocell' may not be closed-loop — only Tencel-branded is guaranteed
- Often blended with elastane, which kills biodegradability
What to look for on the label
Lenzing TENCEL™ branding with the EU Ecolabel or FSC-certified pulp source.

Frequently asked
Is Tencel better than bamboo viscose?+
Yes for environmental impact. Most bamboo fabric is viscose-process bamboo, which uses carbon disulfide and rarely recovers it. Tencel is the cleaner regenerated cellulose option.
How does Lyocell compare to cotton?+
It uses far less water and pesticides, drapes more like silk, and dries faster, but is typically more expensive.

How to judge Lyocell (Tencel) in a real product
A material is never good or bad on its own — it is good or bad for a specific job, at a specific lifespan. Lyocell (Tencel) performs well where its strengths match how the product is used, and poorly where a different fibre or feedstock would last longer with less impact.
The two questions that decide most of the footprint are how long the product survives normal use, and what happens to it afterwards. A durable item kept for a decade almost always beats a lower-impact material replaced every year, which is why we weight lifespan alongside sourcing.
Blends complicate everything. Mixed materials are much harder to recycle because the components must be separated chemically, so single-material products — or blends above roughly 95% one input — are usually the better end-of-life choice.
Lyocell (Tencel) vs common alternatives
| Factor | Lyocell (Tencel) | Conventional alternative | What to look for |
|---|---|---|---|
| Durability | Depends on weave/grade | Often optimized for cost | Warranty, GSM or gauge |
| Chemical load | Lower when certified | Often untested residues | OEKO-TEX STANDARD 100 |
| Traceability | Traceable when certified | Rarely disclosed | Named mill or supplier list |
| End of life | Best when unblended | Usually landfill | Single-material construction |
| Microplastic shedding | None if natural | High for loose synthetics | Fibre type on the label |
Buying checklist for Lyocell (Tencel)
- Match certification to fibreGOTS for organic naturals, GRS for recycled synthetics, FSC for wood and paper.
- Check the composition percentage“Contains organic” can mean 5%. Look for the exact number.
- Prefer repairable constructionReplaceable parts and standard fastenings extend life far more than material choice.
- Read care instructionsCold-wash, line-dry items keep their finish and shed less over time.
How to verify a Lyocell (Tencel) claim in three minutes
- Find the composition label. Exact percentages, not marketing adjectives.
- Look up the certificate. Search the certifier's public register for the brand or licence number.
- Check the scope and expiry. Confirm the certificate is current and covers the product you are buying.
- Compare lifespan. Pick the option you will realistically keep longest at similar quality.
Frequently asked
Is Lyocell (Tencel) better than conventional options?+
Usually yes on the specific dimension it is certified for, and only when the certification is current and covers the product. It is not automatically better across every dimension — durability and end-of-life handling still matter.
Which certification should I look for with Lyocell (Tencel)?+
Match the mark to the material family: GOTS for organic natural fibres, GRS or RCS for recycled content, FSC for wood-based inputs, and OEKO-TEX STANDARD 100 for chemical residue on finished goods.
Does a blend ruin the benefit?+
It reduces it. Blends are harder to recycle and often shed more. If a blend is unavoidable, prefer a high single-fibre share and a construction that can be repaired.
