Fibre business Lenzing Group has revealed that its Tencel fibres are now certified with the Ecocert eco-friendly logo.

Tencel, used primarily in the textile industry but also for non-woven materials and technical applications, can now be labelled with the Ecocert logo.

The Ecocert standard - Ecological & Recycled Textile Standard (ERTS) - stands for eco-friendly production processes and high social standards during production.

Products awarded the logo have to demonstrate the requirements are adhered to from the raw material, to production and to sales through to the end of the product life cycle.

"For Lenzing, certification involved the extensive testing of production including all of the raw and auxiliary materials used, the waste water which is produced and the emissions into the air according to strict specifications from Ecocert," the company said.
