For anyone comparing wood based fibres
LENZING ECOVERO is viscose, not TENCEL
LENZING ECOVERO is a branded viscose with a wood and mill story. We read it as Okay. It is not TENCEL and it is not lyocell. Recycled pulp in some versions does not change that. Ecolabels and OEKO-TEX check process and limits. They do not raise a health number.
Why it matters for your body
LENZING ECOVERO is a brand name on a viscose fibre. Lenzing describes it as cellulose from wood, made to use fewer resources than generic viscose, and soft in a way that suits dresses and knits (Lenzing, ECOVERO). The cloth can feel as nice as other viscose. The question is what the brand name changes, and what it does not.
It does not change the fibre class. Viscose is regenerated cellulose made by the viscose process (EU textile fibre names, Annex I). Lenzing’s own process notes put ECOVERO on the viscose route, and put lyocell on a different one: pulp dissolved in a solvent the mill recovers (Lenzing, fibre technologies). The brand list says the same thing in plainer clothes language. TENCEL is the brand for lyocell and modal. ECOVERO is the brand for this viscose (Lenzing, brand overview).
That route still uses carbon disulfide. Lenzing says its mills cut emissions compared with generic viscose. That is a lower impact version of the same chemistry, not a different chemistry.

The public read: Okay
We name a public verdict and leave the internal math unpublished. The high level method is on the scoring method.
LENZING ECOVERO: Okay. It is viscose, not TENCEL.
Okay means a fair everyday fibre when you can see the name, tighter than unnamed viscose, and not the jump to Better choice we use for lyocell. The maker’s wood sourcing and mill story are real process claims. They are the reason this is not filed with commodity viscose. They are not a new biology, and they are not TENCEL.
Explicitly not the same as TENCEL
TENCEL Lyocell is Better choice. If a product page says “ECOVERO, like TENCEL” it is flattening two fibres into one mood. They share a company and a wood origin. They do not share a process. TENCEL Modal is modal. Modal is Okay. Named modal such as TENCEL Modal tells you the mill, which is useful, but it is still modal, and it is not ECOVERO.
Unnamed viscose, rayon, and bamboo viscose stay Be careful. Buying ECOVERO does not upgrade the viscose blouse next to it on the rail. The name has to be on the fibre you are actually holding.
Recycled pulp, ecolabels, and limits
Some ECOVERO is made with textile waste in the pulp as well as wood. Lenzing describes that version under its REFIBRA name and says it can meet a recycled content standard. It is still viscose. Recycled feedstock does not make it polyester, and it does not make it lyocell. The Global Recycled Standard tracks recycled content and adds environmental and chemical requirements at certified sites (Textile Exchange, GRS). That is a chain and process check. It does not raise a TFD health number.
The maker also says ECOVERO carries the EU Ecolabel, which is an environmental label on how the fibre is produced. Read that as a process claim from the company, the same way you would read any other mill badge. OEKO-TEX Standard 100, if it is on the garment, tests the article for harmful substances (OEKO-TEX Standard 100). Neither mark raises a TFD health number. Dye, finish, and any elastane line still sit on top of the fibre.
What to look for on the label
- LENZING ECOVERO, or ECOVERO viscose: this fibre. Public read: Okay.
- Words that pair it with TENCEL: marketing. The processes differ.
- TENCEL Lyocell: Better choice, on the lyocell page.
- TENCEL Modal: modal, not ECOVERO.
- Viscose or rayon with no ECOVERO name: Be careful.
- ECOVERO with REFIBRA or a GRS mark: still viscose. Not a health number raise.
- EU Ecolabel or OEKO-TEX: process and limit checks, not a health number raise.
