Lyocell is a manufacturing process of rayon which is much more eco-friendly than its relatives modal and viscose. Lyocell is made in a closed-loop system that recycles almost all of the chemicals used. “Lyocell” is the generic name of the manufacturing process and fiber. Tencel® is the brand name of the lyocell commercialized by the company Lenzing AG. Tencel® is made from eucalyptus from PEFC certified forests. Eucalyptus trees grow quickly without the use of pesticides, fertilizers or irrigation.
Just like rayon and viscose, lyocell is 100% biodegradable.
