Lenzing Innovation at Techtextil 2019: LENZING™ Lyocell fibers – plastic free for aquatic farming

The Lenzing Group, world market leader in specialty fibers based on the renewable material wood, today introduced the botanic solution for marine application, in particular for aquatic farming, to the public at the Techtextil Frankurt Fair. The wood-based LENZINGTM branded lyocell fibers are used for the construction of ropes and nets in order to support the cultivation of marine cultures such as mollusks, mussels and edible seaweed to reduce plastic in the sea.

Plastic a serious problem for our marine environment

Annually, about 8 million metric tons of plastics end up in the ocean, resulting in an estimated 165 million tons of plastic debris, currently floating in the marine environment, threatening the health and safety of marine life. The loss of conventionally used synthetic fibers and plastics in the ocean accounts for 80 % of all marine pollution.1 This is not only dangerous for marine life but also for humans as we consume some of these micro plastics through our food. “The development of 100% wood based mussel nets with LENZING™ Lyocell fibers contribute to the reduction of the annual plastic quantity in marine environment”, says Marine Crnoja-Cosic, Head of Application Development New Business Areas.

LENZING™ Lyocell innovation for the marine industry

The Lenzing Group initiated a project in collaboration with two major partners, Sächsisches Textilforschungsinstitut e.V. (STFI) and FIUM GmbH & Co. KG – Institut für Fisch & Umwelt (FIUM) in order to develop a sustainable solution for the marine industry, which does not compromise mechanical performance. There are many different methods of using textile structures as a support for the growth of marine organisms. The important feature of the present invention is that the textile structure is made of wood-based cellulosic fibers. This gives the advantage that any of the textile structure which is released into the environment due to accident, storm damage, negligence or any other cause will degrade in a reasonable time and not leave non- degradable residues.

Up to now, nylon and polypropylene are most commonly used for rope and net materials. Although these materials are durable and have a sufficient strength, they do not have a natural origin and are not marine biodegradable. They stay in the oceans for years. Nets and ropes consisting out of LENZING™ Lyocell fibers proved that they have sufficient strength to carry the weight of the growing cultures without breakage and have the big advantage of biodegradability in the oceans.

Proved by tests

The cooperation partner Sa?chsisches Textilforschungsinstitut e.V. constructed different prototypes and replicates out of LENZING™Lyocell fibers in March 2018. Thereafter, an initial underwater material test was started in the Baltic Sea. The prototypes were installed in 6 to 10 meters depth at an artificial reef platform in Rostock Nienhagen. The objective of the trial was to proof that marine applications produced out of LENZING™ Lyocell fibers can fulfill the key properties of conventional marine supports, which are sufficient strength to carry the weights of the growing cultures without breakage. Moreover, the trial should investigate if LENZING™ Lyocell fibers represent a pleasant environment for particular marine organisms and also proof the marine biodegradability after usage.

After four organized dives by our project partner FIUM, first test results were available. All LENZING™ Lyocell fibers represent an appealing growing material for marine organisms. Overall 14 different sea dwellers like blue mussels, crustaceans, echinoderms or snails adhered on the test material. First test results regarding performance and biodegradability were promising.2

Compostability and biodegradeability are key

Sustainability advantages in aquatic farming are particularly evident, given the fact that the material is being used directly in the oceanic eco system. LENZING™ Lyocell Standard fibers are certified as compostable and biodegradable under industrial, home, soil and also under marine conditions. If pieces of the nets break off, they will harmlessly decompose and have no influence on marine organisms. In order to close the sustainability loop, the nets can be composted after harvesting and processing.

Further developments

“This development brings sustainable solutions to aquatic farming encouraging Lenzing to assess and establish further steps towards commercialization, together with innovative value chain partners”, says Crnoja- Cosic. “Furthermore, future development will focus on optimizing the nets construction for more durable products broadening the scope of 100% Lyocell based marine nets in marine environment,” concludes Crnoja- Cosic. “.

TENCEL™ Lyocell - HV100 achieves global denim availability in six months; Vol. 2 debuts at Kingpins Amsterdam

When TENCEL™ Lyocell - HV100 debuted at last year’s Kingpins Amsterdam in October, 17 mill partners across five countries presented fabrics featuring the new fiber. Just six months on, participation has more than doubled, evolving into a global network that spans nine countries and four continents, signaling both strong industry momentum and growing demand.

Lenzing unveils three-tier cellulosic fiber portfolio for next generation protective wear

The Lenzing Group, a leading supplier of regenerated cellulosic fibers for the textile and nonwovens industries, today introduces Lenzing Solutions for Protective Wear. This integrated three-tier portfolio is anchored by LENZING™ FR fibers at the highest protection tier for inherent flame resistance and brings together complementary solutions including TENCEL™ Lyocell fibers, both EU Ecolabel-certified² and derived from certified or controlled wood sources³, within a unified protective wear architecture for the first time. The launch marks the most significant expansion of Lenzing’s protective wear business since the company pioneered inherently flame-resistant cellulosic fiber in 1977, and comes as the global personal protective equipment (PPE) market accelerates toward an estimated USD 130 billion by 2033⁴.

Reju opens its first R&D Center in the U.S. in Conshohocken, Pennsylvania

Reju, the company specializing in textile regeneration, today announced the opening of a Research and Development (R&D) Center in Conshohocken, Pennsylvania, the company's first proprietary research center in North America. Located within Technip Energies' existing Advanced Materials and Catalysts research center, the lab will allow Reju to accelerate the rollout of its recycling technologies and develop its next-generation circular solutions.
