• Results of experiments conducted by the University of California’s prestigious Scripps Institution of Oceanography in San Diego provide further scientific proof that LENZING™ fibers offer an effective substitute to synthetic fibers that are part of the pressing problem of plastic pollution in our oceans.

Lenzing/San Diego – The Lenzing Group, a world-leading provider of wood-based specialty fibers, has received further scientific proof of the biodegradability of its fibers. In a study published in October 2021 , scientists from the prestigious academic research institute Scripps Institution of Oceanography (SIO) at the University of California, San Diego confirmed that wood-based cellulosic fibers biodegrade in the ocean within a short period of time at the end of their life cycle, making them a better alternative to fossil-based fibers. The research was the result of an independent project trying to understand the “end-of-life” scenarios for textiles and nonwovens discarded in the environment.

SIO has a global reputation for being one of the oldest, largest and most important marine research centers worldwide. In this study, SIO compared the degradation processes of nonwovens made from fossil-based synthetic materials such as polyester with those of cellulosic materials such as Lenzing’s wood-based lyocell, modal and viscose fibers in specific scenarios – under various real oceanic conditions and controlled aquaria conditions. The results of these experiments are striking: while wood-based cellulosic fibers fully biodegraded within 30 days, the fossil-based fibers tested were practically unchanged after more than 200 days.

The biodegradability of LENZING™ fibers was also tested in the laboratory of Organic Waste Systems (OWS) in Belgium – one of the world's leading companies in biodegradability and compostability testing – which showed data confirmed by those found with the real-life measurements at Scripps. The OWS assessment was conducted in accordance with applicable international standards and reflects relevant natural and artificial conditions in which biodegradation can occur. Certificates from the certification organization TÜV Austria show that LENZING™ fibers rapidly biodegrade in all test environments (soil, industrial composting, home composting, fresh water and marine water) within the time frames set by the applicable standards.

Lenzing also welcomes the EU’s targeted measures to combat plastic waste in general, such as those relating to the single-use plastic directive (EU) 2019/9043. In its recently adopted guidelines for implementing the directive, the EU Commission stipulates the specific products that fall under this category, which is a well-needed effort to provide clarity to the EU member states for their joint campaign against environmental pollution from plastic waste. Lenzing’s wood-based, biodegradable cellulosic fibers can be part of a sustainable and innovative solution to this man-made problem that will continue to grow. As of July 2021, the single-use plastic directive sets out standardized labelling requirements for certain products, either on packaging or on the products themselves, which include plastic-based feminine hygiene products and wet wipes for body care or household use. This is a start to tackle the problem: educate the consumer and offer alternative materials with better circularity.

INDA, the Association of the Nonwoven Fabrics Industry, wrapped up its 15th annual World of Wipes® International Conference, July 12-15, with a presentation of the World of Wipes Innovation Award® to Kimberly-Clark Corporation and the highest attendance record in six years.

This year’s WOW conference welcomed 475 enthusiastic professionals from 14 countries to its in-person World of Wipes® (WOW) International Conference to advance their wipes business. Held in Atlanta, GA, the conference was notable as the first in-person conference in the nonwovens and engineered fabrics industry in 500 days due to the pandemic.

Industry professionals from 33 global companies delivered presentations and answered questions in sessions that included Wipes and the Growing Plastics Debate, Regulatory Requirements for Disinfecting and Sanitizing Wipes, Trends in the Wipes Markets and Among Consumers, Wet Wipe Preservative Innovations, Covid-19 Impacts on Wipes Consumption and Cleaning Habits, Sustainable Wipes Packaging and Dispensing, Nonwoven Substrates for More Sustainable Wipes, and Flushable Wipes: Loved by Consumers, Wrongly Accused by Utilities.

Highlights included the announcement of Kimberly-Clark Scott® 24-Hour Sanitizing Wipes as the winner of this year’s World of Wipes Innovation Award®. The annual award recognizes the product that most expands the use of nonwovens and demonstrates creativity, novelty, uniqueness, and technical sophistication within the entire nonwovens wipes value chain.

Other highlights included the presentation of the 2021 INDA Lifetime Technical Achievement Award to John Poccia. The annual award is nominated by INDA’s Technical Advisory Board and presented to an individual whose technical achievements over a long-standing career have significantly contributed to the technical advancement, success, and growth of the nonwovens industry.
