From the Sector

The Lenzing Group, a leading supplier of regenerated cellulose fibers for the textile and nonwovens industries, will be presenting its sustainable innovations at Hannover Messe 2025, the world’s leading trade fair for the industry, from March 31 to April 4. As a co-exhibitor at the EU Commission’s stand, the leading integrated fiber group is representing a European flagship company in the clean industry.

Lenzing is currently the only producer of regenerated cellulosic fibers with a verified, science-based net-zero target. Lenzing is also proactively developing and promoting innovation to provide economically viable and scalable solutions to the global textile waste problem and accelerate the transition to a circular economy model.

A current example of Lenzing’s pioneering work in this field is the CELLFIL project, which was launched in 2024 and is co-funded by the EU with EUR 6.9 mn. As part of this project, Lenzing is working with the non-profit organization RTDS Group and 13 other partners from research and industry to promote the scaling of lyocell filaments.

Since 2021, Lenzing has been working with Swedish pulp producer Södra to jointly develop new processes for recycling used textiles on an industrial scale. The project was supported in 2023 as part of the LIFE 2022 program with a grant of EUR 10 mn from the EU.

Another example of Lenzing’s innovative strength is the project “Glacial Threads: From Forests to Future Textiles”, which combines glacier protection and textile recycling and will be presented at HANNOVER MESSE 2025.

Geosynthetics have become an indispensable part of the construction industry. PP nonwovens, for example - mechanically bonded continuous fibres made from specially UV-stabilised polypropylenes - are often used in blanket form as barriers, screens and filters, and their strength extends the service life of construction projects. Whether for road construction, or as barrier on glaciers or against weeds - there are myriad applications.

TenCate Geosynthetics uses the PURE LOOP ISEC evo technology to recycle this type of PP nonwoven. The European company, with locations in Austria, France and the Netherlands, is specialised in the development and production of geotextiles for modern civil engineering applications. The edge trimmings and production rejects generated during manufacturing used to be recycled at the Linz site, but not fed back into the company's own production process.

"The demands on us were high," recalls Patrick Wiesinger, project manager at PURE LOOP. "The PP nonwoven is highly tear resistant, which means its a very challenging recycling process. Our ISEC evo machine conserves the quality of the production waste really well during recycling, so we were able to achieve the specified increase in quality for the recyclates."

Another advantage of PURE LOOP technology is the wide range of shapes in which the production scrap can be delivered for processing. "Our ifeed technology with double feed ram system and singleshaft shredder offers the ideal conditions for direct processing of these large rolls - and without the need for prior preparation of the input material by employees before the material is fed into the recycling process", emphasizes Patrick Wiesinger. With the ISEC evo recycling machine TenCate can now manufacture its high-strength PP nonwoven product with a recyclate content of up to 10 percent.
