From the Sector

• Full utilization of production capacity possible at the site
• New EU environmental requirements will be fully and promptly satisfied starting in 2024

The Lenzing Group, a global provider of wood-based specialty fibers for the textile and nonwoven industries, is investing GBP 20 mn (equal to EUR 23.3 mn) to build a new, state-of-the-art wastewater treatment plant at its site in Grimsby, United Kingdom. The investment is part of the company’s plans to reduce wastewater emissions by 2022.

Once it has implemented this project, Lenzing will have biological wastewater treatment plants that meet the best available techniques (BAT) quality standard at all its production sites. The plant design, which will employ a new technology developed as part of a research project, is fully aligned with the UK regulator and supported by the local authorities.

The site’s current wastewater situation complies fully with the EU Water Framework Directive as well as all local laws and regulations. The investment has been approved by the Supervisory Board, ensuring that construction can start this year and the plant will be commissioned well before the UK-ratified EU directive1 goes into effect. This will be the largest investment since opening this lyocell site, which manufactures premium products for technical and innovative market segments, among other things.

Responsible water use
After modernizing the wastewater treatment plant at the company’s Purwakarta site in Indonesia, the construction of the new plant in Grimsby marks another big step toward reducing the Group’s wastewater emissions 20 percent by 2022 (against a 2014 baseline). Responsible water use is one of the core elements of Lenzing’s “Naturally positive” sustainability strategy and is largely executed by using water efficiently in manufacturing and employing state-of-the-art water treatment technologies.

Sateri, one of the world’s largest viscose producers and a member of the RGE group of companies, continues its collaboration with Infinited Fiber Company, a textile fibre technology group based out of Finland, and participated in the company’s latest EUR30 million funding round completed on 30 June 2021. In addition to existing investors like Sateri, Infinited Fiber Company has attracted new investors including adidas and BESTSELLER.

This securement of new funding follows Infinited Fiber Company’s April announcement of plans to build a flagship factory in Finland in response to the strong growth in demand from global fashion and textile brands for its regenerated textile fibre Infinna™. The factory, which will use household textile waste as raw material, is expected to be operational in 2024 and to have an annual production capacity of 30,000 metric tons. The new funding enables Infinited Fiber Company to carry out the work needed to prepare for the flagship factory investment and to increase production at its pilot facilities in the years leading to 2024. The engineering progress supported by the additional funds also accelerates Infinited Fiber Company’s ongoing collaboration and potential technology licensing with Sateri.

Sateri strategically contributes to RGE’s commitment and strategic business direction. Sateri has developed and produced a diverse range of circular and sustainable products including Lyocell and FINEX™, which is made from recycled textile waste. The in-house R&D efforts and the investment in Infinited Fiber Company are part of RGE’s $200 million investment commitment to advance next-generation textile fibre innovation and technology.

FibreCoat GmbH from Aachen, Germany, together with DBF Deutsche Basalt GmbH, developed a completely new type of fibre material to shield electromagnetic radiation from digital end devices, medical technology or e-car batteries cheaply and effectively. The joint project was awarded the overall prize of the“ IQ Innovationspreises Mitteldeutschland“ on 24 June in an online event broadcast live from Leipzig.

The prize is endowed with €15,000 and was sponsored by the Halle-Dessau, Leipzig and East Thuringia Chambers of Industry and Commerce.

Electromagnetic radiation from smartphones, hospital diagnostics and electric car batteries must be shielded so that they do not inter-fere with each other. To prevent mutual interference, they have so far been covered with metal fibre fabrics, a very time- and energy-consuming and thus expensive procedure. The new material from Basalt Faser GmbH and FibreCoat GmbH prevents this with a fibre core made of melted, thinly drawn basalt, which is coated with aluminium and bundled into the so-called AluCoat yarn. This yarn remains just as conductive and shielding, but is lighter, stronger, cheaper and more sustainable than previous alternatives. In addition, there are further advantages:

• The number of process steps required is reduced from ten to one.
• 1,500 metres of yarn are produced per minute instead of the previous five metres.
• The energy required is only 10 per cent of the previous amount.

The result is a price that is twenty times lower.

The textile made of AluCoat fibres is versatile and flexible: as wallpaper it can shield 5G radiation in offices or medical rooms or encase batteries and thus ensure the smooth functioning of electric cars. AluCoat is already being used in some companies. A European fibre centre in Sangerhausen is being planned for mass production.

The two innovative companies DBF Deutsche Basalt GmbH and FibreCoat GmbH from East and West combine the two materials basalt and aluminium to protect against electromagnetic radiation. In doing so, they coat basalt with aluminium and, through this novel combination, create an inexpensive, sustainable and quickly produced alter-native for a market worth billions.

FibreCoat GmbH from Aachen is a spin-off of the Institut für Textiltechnik (ITA) of RWTH Aachen University; the managing directors Dr Robert Brüll and Alexander Lüking and Richard Haas have completed their doctorates at the ITA or are in the process of preparing their doctorates. Georgi Gogoladze, Managing Director of Deutsche Basaltfaser GmbH, also studied at RWTH Aachen University. The two managing directors Brüll and Gogoladze know each other from their student days.

Teijin Carbon Europe introduces a new thermoplastic carbon fiber tape (TPUD) based on PPS. The new Tenax™ TPUD with PPS matrix allows entry in new cost-sensitive markets while offering the typical TPUD advantages like high resistance to chemicals and solvents, low flammability, storage or shipping at room temperature and recyclability.  

Due to its flame retardant properties and low smoke emission, it can be used in interior applications of aircraft or rail vehicles, among others. The maximum continuous operating temperature is up to 220 °C. Very low water absorption, excellent creep resistance even at elevated temperatures and high dimensional stability round off the property portfolio of this new TPUD. It is therefore also suitable for demanding applications in the aerospace, oil & gas, sporting goods or industrial sectors, while remaining cost-effective. These properties make the product perfect for highly automated processing routes such as ATL or AFP in combination with overmolding for complex geometries. Production start for the Tenax™ TPUD with PPS matrix is the first quarter in 2021.

For almost 10 years, unidirectional tapes (TPUD) have been manufactured from carbon fibers and thermoplastics in Heinsberg, Germany. The semi-finished products have so far been offered with PEEK or PAEK – and PPS is now added to the list of available matrixes. PPS allows a lower process temperature compared to PEEK or PAEK. For the industrial market in particular, increasing the production rate to make processes more cost-efficient is an opportunity.
