Inspiring group action for sustainable practices and a circular economy in the nonwovens and textile value chain, the Lenzing Group, a leading provider of regenerated cellulose for the textile and nonwovens industries, has developed a novel, cutting-edge concept that helps to protect our glaciers in a sustainable way. The talk, “Glacial Threads: From Forests to Future Textiles,” was given at the United Nations Office in Geneva’s Palais des Nations as part of the celebrations for the International Day of Forests.
Global warming is having a major effect on glacier melting. Snow and ice are shielded by geotextiles.
However, because the nonwovens used for this are comprised of fibers derived from fossil fuels, microplastics may enter the food chain through tiny creatures and animals and may reach the valley through streams. The sustainable answer to this issue is nonwovens constructed of cellulosic LENZING fibers, which can be fully recycled and biodegrade at the end of their life cycle. During an initial field test on the Stubai Glacier, the new material composed of LENZING fibers covering a short area was tested. The melting of four meters of ice was prevented. This was verified by research done on the Stubai Glacier in Tyrol, Austria, by the University of Innsbruck and the Austrian glacier lift operators.
The pilot project was successfully expanded to include all glaciers in Austria that are visited by tourists in 2023. According to Berndt Köll, Emerging Business Development at Lenzing, “We are delighted with the positive results and see the project as a sustainable solution for glacier protection – not only in Austria but also beyond the country’s borders.” In addition, the concept won first prize in the prestigious Swiss BIO TOP Awards for innovations in wood and materials last year.
Adherence to circularity
Lenzing sees this ground-breaking innovation project as a chance to spur cooperative efforts toward circularity and sustainable practices throughout the textile value chain. Lenzing is collaborating with a group of dedicated and creative partners to convert geotextiles into new textile fibers that will enable them to be used again as clothing. Geotextiles are typically only used for a maximum of two years, after which the nonwovens are disposed of.
The recycling of nonwoven materials intended for use as geotextiles has been successfully tested in the first part of the pilot project, and a stylish “Glacier Jacket” has been manufactured to demonstrate the viability of geotextile recycling. In addition to Lenzing, the network comprises the mechanical recycling expert Marchi & Fildi Spa, the denim fabric producer Candiani Denim, and the cutting-edge design company Blue of a Kind.
“This groundbreaking innovation project brings together trusted like-minded companies and partners across the supply chain, demonstrating the companies’ shared vision and commitment to the circular economy,” said Florian Heubrandner, executive vice president of Lenzing’s commercial textiles division. The partnership’s ability to spur innovation and sustainability, lessen environmental effect, and promote coordinated action against climate change for a worldwide impact in the textile sector is a testament to its potency.
Vice President Corporate Sustainability at Lenzing, Krishna Manda: “We are at a critical point that requires transformative change for global impact as the climate emergency accelerates glacier melting.” Our imaginations are sparked by nature, which leads to extremely original ideas. This innovative project exemplifies the harmonious relationship between technology and environment and serves as a call to action for group action, demonstrating collaborative circular sustainable practices as part of Lenzing’s continued commitment to fusing innovation and sustainability. By working with our network of committed industry professionals, we can significantly improve the earth and protect coming generations. This project serves as an illustration of the potential that arises when people work together.
The concept was presented on March 21, 2024, as part of the International Day of Forests celebrations at the Palais des Nations, the headquarters of the United Nations Office at Geneva (UNOG). The innovative idea was artistically staged by one of the most influential contemporary artists, the Italian Maestro Michelangelo Pistoletto.
