From the Sector

• Excellent project to encourage ingenuity among young students
• Experiment on biodegradability of textiles and nonwovens produces impressive results
• EUR 30,000 in prize money for a total of 209 participating schools in and outside Austria
• Lenzing views supporting these kinds of projects as part of its sustainability mission

Lenzing – The Association of Chemistry Teachers in Austria – known by its German abbreviation, VCÖ – has been holding project competitions that thrill students and take them beyond the traditional syllabus for 30 years. Every two years, it highlights a key topic for ninth- and tenth-graders to explore by conducting special experiments and learning from their observations and conclusions.

This year, the 16th installment of the competition is called, “Achieving a cleaner climate and a circular economy with chemistry”. These topics are also near and dear to the heart of globally active fiber manufacturer Lenzing. That’s why the company promptly announced that it was prepared to support this project competition in several different ways. First, Lenzing made a contribution toward the sponsorship fund totaling EUR 30,000. Second, it initiated a special prize on biodegradability – a topic of growing importance given the huge challenges involved in reducing plastic waste. Finally, Lenzing placed a recognized expert at the students’ disposal to provide assistance and answer questions: Michaela Kogler, Project Manager Nonwovens & Technical Products.

Teaming up with rainworms

Two teams were tasked with biodegrading different fibers – just like those used to produce textiles and nonwovens – with the active participation of worms. Students at BRG solarCity in Linz buried fiber nonwovens, a basic material used in wet wipes and other products, in soil that was populated with numerous rainworms, while students at Vöcklabruck Junior High School for Sports and Integration layered textiles into a vermicomposting bin. Both experiments intended to determine the extent to which certain materials would biodegrade quickly. As it turned out, both projects showed that wood-based fibers, like those that Lenzing manufactures for the textile and nonwoven industry, break down very rapidly into natural constituents that swiftly pass into the soil. In contrast, fossil-based plastics such as polyester or polyethylene cannot be decomposed by worms or bacteria but remain in the soil, sometimes for hundreds of years.

The prizes for this year’s competition were awarded on June 11. The competition attracted entries from no fewer than 209 schools, including 11 from outside Austria. For more information on the projects and the winners, visit www.vcoe.or.at.

Paper Converting Machine Company (PCMC) has announced its industry-leading wet wipes folding machines the Rx200 and Mako Clipper are now available with high-content alcohol, measuring as much as 70 percent.

Previously, PCMC wet wipes machines operated with less than 20 percent alcohol, producing disinfectant wipes for personal, home, industrial and automotive use. However, the COVID-19 pandemic has created a spike in demand for sanitizing wipes that contain at least 70 percent alcohol, the key component in killing or deactivating viruses.

To help manufacturers meet the increased demand, PCMC redesigned its Rx200 and Mako Clipper to safely operate with high-content alcohol. The new designs feature increased air exchange for better ventilation and additional sensors to eliminate the risk of flash points and fires. The machines also include IDS 150/300 integrated dual stackers and a redesigned Mako saw to meet more stringent regulations and higher machine performance expectations.

On Thursday, September 24, the Lenzing Group, a leading manufacturer of wood-based cellulose specialty fibers, and Hof University opened a new Nonwoven Development Center (VEZ). As a strategic partner, Lenzing has access to a state-of-the-art development line at the campus in Münchberg with immediate effect. This offers new opportunities for sustainable fiber and nonwoven innovations for a wide range of applications including hygiene, body care and medical.

In line with the sCore TEN corporate strategy, the Lenzing Group is focusing on sustainable innovations, which are agreed in an optimum manner to the needs of the value chain. „We offer our customers and partners a decisive competitive advantage: agility. The pilot plant in the VEZ allows the resource-efficient development of fiber and nonwoven innovations on a small scale”, Jürgen Eizinger, Vice President Business Unit Nonwovens at Lenzing, explains.

The VEZ was completed according to schedule in September 2020, after Lenzing and the University of Hof signed a cooperation agreement for its use in 2019. The timing is perfect. Developments at political level, such as the directive (EU) 2019/904 of the European Parliament and of the Council of 5 June 2019 on the reduction of the impact of certain plastic products on the environment, increase demand for responsibly manufactured nonwovens. The so-called Single-Use Plastics Directive aims at building awareness and greater transparency with regard to wet wipes and feminine hygiene products.

With its VEOCEL™ branded wood-based cellulose fibers, Lenzing has been laying the foundation for many years for sustainable nonwoven applications and will test and develop innovative ideas using the new possibilities offered by the VEZ. „We are noticing increasing interest in sustainable concepts from biodegradable cellulose fibers“, Jürgen Eizinger sums up the market development of the last months and adds: „We are aware that the fibers used have an enormous influence on the final product. For this reason our commitment goes beyond fiber production.“

With the spunlace pilot plant at the VEZ, Lenzing will support customers and partners more intensively in the development of new nonwoven applications and at the same time promote cooperation in the field of marketing. In the previous year, the company already established new certification standards for the VEOCEL™ brand. Since then certified manufacturers can only use the VEOCEL™ logo with blends of biodegradable cellulose fibers. With this measure, the VEOCEL™ brand allows consumers to make a more conscious product selection.

With its #ItsInOurHands environmental initiative, the VEOCEL™ brand also actively contributes to creating awareness. More detailed information can be obtained on itsinourhands.com.

• Organic Waste Systems and TÜV confirm fiber biodegradability also in fresh water
• All white LENZING™ Viscose, Modal and Lyocell fibers are now certified for all environments
• Global legislators aim at limiting plastic waste persisting in the environment for centuries
• EU Single-Use Plastics Directive partly regulates usage of plastic products
• Biodegradable materials such as wood-based fibers are the best alternative to single-use plastics

The Lenzing Group received confirmation of the full biodegradability of its fibers in fresh water by the independent research laboratory Organic Waste Systems (OWS). The new and existing international certifications conducted by OWS and issued by TÜV Austria verify that LENZING™ Viscose fibers, LENZING™ Modal fibers and LENZING™ Lyocell fibers are biodegradable in all natural and industrial environments: in the soil, compost as well as in fresh and in marine water.

The biodegradability of cellulosic products and the synthetic fiber polyester was tested in fresh water at OWS according to valid international standards, e.g. ISO 14851. At the end of the trial period, LENZING™ wood-based cellulosic fibers, cotton and paper pulp were shown to be fully biodegradable in fresh water in contrast to synthetic polyester fibers. The fact that synthetic materials are not biodegradable leads to major problems in wastewater treatment plants and potentially marine litter. In turn, this not only harms fish and birds living in and close to the oceans but also all marine organisms and us humans.

“The Lenzing Group operates a truly circular business model based on the renewable raw material wood to produce biodegradable fibers returning to nature after use. This complete cycle comprises the starting point of the core value of sustainability embedded in our company strategy sCore TEN and is the ‘raison d’etre’ of our company”, says Stefan Doboczky, Chief Executive Officer of the Lenzing Group. “In living up to this positioning, we not only enhance the business of our suppliers, customers and partners along the value chain but also improve the state of the entire textile and nonwovens industries.”

Both the textile and nonwovens industries face huge challenges with respect to littering. If current trends continue, the oceans could contain more plastic than fish by 2050. Therefore, legislative bodies worldwide can no longer ignore the issue and have moved towards plastics legislation aimed at limiting the vast amount of waste. In response, European lawmakers issued the Single-Use Plastics Directive currently being transposed into national legislation in the EU member states.

Conventional wet wipes and hygiene products mostly contain plastic and were thus identified as one of the product categories to be singled out. Less polluting alternatives are generally encouraged by NGOs and legislators, e.g. products made of biodegradable wood-based cellulosic fibers. Plastic waste including microplastic can persist in the environment for centuries. In contrast, biodegradable materials are the best alternative to single-use plastics because they fully convert back to nature by definition and thus do not require recycling.
