From the Sector

The “Cellulose Fibres Conference 2024” held in Cologne on 13-14 March demonstrated the innovative power of the cellulose fibre industry. Several projects and scale-ups for textiles, hygiene products, construction and packaging showed the growth and bright future of this industry, supported by the policy framework to reduce single-use plastic products, such as the Single Use Plastics Directive (SUPD) in Europe.

40 international speakers presented the latest market trends in their industry and illustrated the innovation potential of cellulose fibres. Leading experts introduced new technologies for the recycling of cellulose-rich raw materials and gave insights into circular economy practices in the fields of textiles, hygiene, construction and packaging. All presentations were followed by exciting panel discussions with active audience participation including numerous questions and comments from the audience in Cologne and online. Once again, the Cellulose Fibres Conference proved to be an excellent networking opportunity to the 214 participants and 23 exhibitors from 27 countries. The annual conference is a unique meeting point for the global cellulose fibre industry.  

For the fourth time, nova-Institute has awarded the “Cellulose Fibre Innovation of the Year” Award at the Cellulose Fibres Conference. The Innovation Award recognises applications and innovations that will lead the way in the industry’s transition to sustainable fibres. Close race between the nominees – “The Straw Flexi-Dress” by DITF & VRETENA (Germany), cellulose textile fibre from unbleached straw pulp, is the winning cellulose fibre innovation 2024, followed by HONEXT (Spain) with the “HONEXT® Board FR-B (B-s1, d0)” from fibre waste from the paper industry, while TreeToTextile (Sweden) with their “New Generation of Bio-based and Resource-efficient Fibre” won third place.

Prior to the event, the conference advisory board had nominated six remarkable innovations for the award. The nominees were neck and neck, when the winners were elected in a live vote by the audience on the first day of the conference.

First place
DITF & VRETENA (Germany): The Straw Flexi-Dress – Design Meets Sustainability
The Flexi-Dress design was inspired by the natural golden colour and silky touch of HighPerCell® (HPC) filaments based on unbleached straw pulp. These cellulose filaments are produced using environmentally friendly spinning technology in a closed-loop production process. The design decisions focused on the emotional connection and attachment to the HPC material to create a local and circular fashion product. The Flexi-Dress is designed as a versatile knitted garment – from work to street – that can be worn as a dress, but can also be split into two pieces – used separately as a top and a straight skirt. The top can also be worn with the V-neck front or back. The HPC textile knit structure was considered important for comfort and emotional properties.

Second place
Honext Material (Spain): HONEXT® Board FR-B (B-s1, d0) – Flame-retardant Board made From Upcycled Fibre Waste From the Paper Industry
HONEXT® FR-B board (B-s1, d0) is a flame-retardant board made from 100 % upcycled industrial waste fibres from the paper industry. Thanks to innovations in biotechnology, paper sludge is upcycled – the previously “worthless” residue from paper making – to create a fully recyclable material, all without the use of resins. This lightweight and easy-to-handle board boasts high mechanical performance and stability, along with low thermal conductivity, making it perfect for various applications in all interior environments where fire safety is a priority. The material is non-toxic, with no added VOCs, ensuring safety for both people and the planet. A sustainable and healthy material for the built environment, it achieves Cradle-to-Cradle Certified GOLD, and Material Health CertificateTM Gold Level version 4.0 with a carbon-negative footprint. Additionally, the product is verified in the Product Environmental Footprint.

Third Place
TreeToTextile (Sweden): A New Generation of Bio-based and Resource-efficient Fibre
TreeToTextile has developed a unique, sustainable and resource efficient fibre that doesn’t exist on the market today. It has a natural dry feel similar to cotton and a semi-dull sheen and high drape like viscose. It is based on cellulose and has the potential to complement or replace cotton, viscose and polyester as a single fibre or in blends, depending on the application.
TreeToTextile Technology™ has a low demand for chemicals, energy and water. According to a third party verified LCA, the TreeToTextile fibre has a climate impact of 0.6 kg CO2 eq/kilo fibre. The fibre is made from bio-based and traceable resources and is biodegradable.

The next conference will be held on 12-13 March 2025.

• Lenzing and Södra – a long-standing partnership for systemic change
• International Textile Manufacturers Federation (ITMF) honored the two companies in the "International Cooperation" category
• EU co-funded recycling project for textiles on an industrial scale

The Lenzing Group, the world’s leading supplier of specialty fibers for the textile and nonwovens industries, and the Swedish pulp producer Södra have received the ITMF Award 2023 in the category “International Cooperation” for their joint achievements in textile recycling and circular economy. The award was presented at the ITMF Annual Conference in Keqiao, China, on November 06, 2023.

The ITMF Award 2023 is given by the International Textile Manufacturers Federation (ITMF) to recognize outstanding achievements and merits in the textile sector in two categories: ”Sustainability & Innovation“ and ”International Cooperation“. Since 2021, the two pioneers have been joining forces in textile recycling, making a decisive contribution to promoting the circular economy in the fashion industry. As part of the cooperation, the companies intend to share their knowledge with each other and jointly develop processes to enable the wider use of cellulose-based used textiles on a commercial scale.

The OnceMore® pulp from Södra, which was jointly developed further by Södra and Lenzing, is subsequently used, among other things, as a raw material for the production of Lenzing fibers with REFIBRA™ technology. The OnceMore® process makes it possible to process and recycle a blend of cotton and polyester.

ITMF paid particular tribute to the joint LIFE TREATS project (Textile Recycling in Europe AT Scale)¹,which was supported by an EU grant of EUR 10m under the LIFE 2022² program and aims to build a large-scale plant at Södra's Mörrum site in Sweden.

Founded by innovators from Stockholm’s KTH Royal Institute of Technology in 2012, Re:NewCell AB (publ) (‘Renewcell’) is a multi-award-winning sustaintech company based in Sweden. The company’s vision is to make fashion circular. Through its patented process, Renewcell is able to recycle cellulosic textile waste, such as worn-out cotton clothes and production scraps, transforming it into a pristine new material called Circulose®.

• The Borvida™ portfolio introduces sustainable base chemicals to Borealis’ range of product offering
• The range will initially be based on non-food waste biomass, and chemically-recycled waste; in the future it will also draw from atmospheric carbon capture
• The traceability of the content will be based on Mass Balance, which is ISCC PLUS certified
• This is the next step in an ambitious sustainability journey, which will see Borealis move away from traditional fossil-based feed

Borealis is strengthening its EverMinds™ circular product offering with Borvida™, a range of sustainable base chemicals.

The Borvida portfolio will offer base chemicals or cracker products (such as ethylene, propylene, butene and phenol) with ISCC Plus-certified sustainable content from Borealis sites in Finland, Sweden and Belgium. The move is part of Borealis’ broader commitment to a Future-Positive Revolution, in which the unrivalled benefits of base chemicals and polymers can be enjoyed at minimal impact to the planet.   

The portfolio will initially comprise Borvida B, from non-food waste biomass, and Borvida C, from chemically-recycled waste. In the future, the range will evolve to include Borvida A, sourced from atmospheric carbon capture. Borvida is complementary and is the building block to Bornewables™, a portfolio of polyolefins based on renewably-sourced second generation feedstocks, and Borcycle™, which offers circular polyolefins produced from mechanically- and chemically-recycled plastic waste.

Borealis produces a wide range of base chemicals for use in numerous industries based on various feedstock, such as naphtha, butane, propane and ethane. Through its olefin units (steam cracker and propane dehydrogenation), it converts these into the building blocks of the chemical industry: ethylene, propylene and C4 hydrocarbons (butylenes, ethyl tertiary-butyl ether (ETBE) and butadiene), and C5-6 hydrocarbons (pygas, phenol) among others.

The basis of the Borvida portfolio is Mass Balance, a Chain of Custody model that enables sustainable content to be tracked, traced, and verified through the entire value chain, offering sustainability-assured products from feedstock to end product. Using this model, circular alternatives can be offered in a cost-effective and environmentally-conscious way, which can be scaled up quickly without compromising on quality or efficiency.

Borvida can be used for a wide range of different polymer and chemical applications, also beyond polyolefins (PO). Non-PO polymers, such as polycarbonates, acrylonitrile butadiene styrene (ABS), super absorbant polymer (SAP) and other chemicals, are utilised for various end applications including coatings, plasticizers, adhesives, automotive, electronics, lubricants, detergents, appliances and sports equipment.

Together with key strategic partners, including Neste and Covestro, Borealis strives to provide a long-term solution in order to allow value-chain partners to meet their sustainability goals. Borvida will enable our customers to increase the sustainability of their products, keeping them ahead of forthcoming legislative changes, and meeting their customers’ demands for climate-conscious products.

Introduced on a smaller scale in early 2020, early renewable base chemicals customers include Covestro. “The use of alternative sustainable raw materials is one important pillar of our strategic ambition to become fully circular”, comments Frank Dörner, Managing Director Covestro Procurement Services GmbH & Co. KG. “The new product line is a good example for joint solutions, another strategic pillar, in order to establish new and reliable supply chains creating benefits for our customers.”

Gina Tricot releases its first collection that has been produced with We aRe SpinDye. The collection is part of Gina Tricot's innovation program Gina Lab. and consists of a coat, shirt, trousers and two bags colored with We aRe SpinDye's method.

With the collaboration, Gina Tricot continues to focus on sustainability, now with the coloring process at the center. Of all the resources that arise during the entire lifespan of a garment - from the production of raw materials, to recycling, 80% is used during the production phase itself. To maximize the effects of the sustainability changeover, an increased focus is required on the entire production process and in particular on the most resource-intensive of them all: the dyeing.

One of Gina Tricot's focus is to explore new methods and technologies in sustainability, which makes the collaboration with We aRe Spin Dye feel just right for us. Together we get a product with more durable and circular fibers, in addition with a more sustainable textile production with a focus on minimal water use. We are extremely proud of this collaboration. says Emma Garrote, Global Production & Sustainability Manager at Gina Tricot.

Gina Tricot is a shining example of an agile organization with short decision-making processes. They have managed to enthuse both the design and production department. It has been crucial to reach the launch of this collection that takes place today, says Andreas Andrén, CEO of We aRe SpinDye®.

Gina Tricot
Gina Tricot is a Swedish fashion brand that offers fashion to women in over 30 countries. Today, Gina Tricot has over 160 stores around Sweden, Norway, Denmark and Finland, as well as e-commerce throughout Europe. With around 1,900 employees, 98% of these are girls. For Gina Tricot, it is important to build pride from the inside out, we are a company that chooses to invest in and highlight women.

We aRe Spin Dye
The company is a Swedish cleantech company that provides and offers a process and platform for production and quality control that enables players in the fashion and clothing industry to significantly reduce their environmental impact. The company's business concept is to establish a new, sustainable and transparent standard for dyeing synthetic textiles in the fashion and apparel industry in a simple and user-friendly way.

Members of TMAS – the Swedish textile machinery association – are proving instrumental in pioneering new sustainable processes for the dyeing, finishing and decoration of textiles.

The wasteful processes involved in these manufacturing stages are only one component in the development of viable circular supply chains for textiles that are now being established in Sweden.

At the recent Conference on Sustainable Finishing of Textiles, held across three separate afternoons on September 30^th, October 1^st and October 7^th, delegates heard that Sweden will introduce extended producer responsibility (EPR) for waste textiles and clothing at the beginning of 2022, ahead of the adoption of a similar European Union-wide EPR system in 2025.

New fibers
Swedish companies are also active in the development of new fibers derived from waste clothing, building on the country’s legacy leadership in pulp and paper production.

At the Sustainable Finishing of Textiles Conference, however, it was said that all of the environmental gains made by such sustainable new fibers can potentially be cancelled out in the further processing they are subjected to – and especially in resource-intensive conventional dyeing, finishing and decoration.

TMAS members Baldwin Technology and Coloreel have both developed solutions to address this issue.

TexCoat G4
During the conference, Baldwin’s VP of Global Business Development Rick Stanford explained that his company’s TexCoat G4 non-contact spray technology significantly reduces water, chemistry and energy consumption in the finishing process. It consistently and uniformly sprays chemistry across a fabric surface and applies it only where needed, on one or both sides.

Instant coloring
Coloreel’s CEO Mattias Nordin outlined the benefits of his company’s technology which enables the high-quality and instant coloring of a textile thread on-demand and can be paired with any existing embroidery machine without modification. This enables unique effects like shades and gradient to be achieved in an embroidery for the first time.

• Major Monforts denim customers continue to pioneer new initiatives that are pushing the boundaries of sustainable production.

Recycling their cotton waste has become one way these companies can do more with less, and at the recent Kingpins24 Flash online event, Sedef Uncu Aki, director of Orta, headquartered in Istanbul, Turkey, announced a new partnership with leading recycling operation Gama Recycle.

Traceable
“Through this local partnership we will supply the waste from our spinning mills and return around 3,000 tons of premium quality cotton back to them,” she said. “We have established a truly controlled and traceable system and partnering with a domestic recycling centre is important because a lot the carbon emissions associated with recycling usually come from transportation.”

Orta’s ZeroMax range meanwhile uses no cotton at all, being based on Lenzing’s Tencel cellulosic fibre, while the company’s involvement in denim production for a recent launch by Levi Strauss, of jeans made with organic cotton and Circulose – a breakthrough material developed by re:newcell of Sweden and partners – was hailed as a further step forward.

To make Circulose, re:newcell repurposes discarded cotton textiles, such as worn-out denim jeans, through a process akin to recycling paper. The incoming waste fabrics are broken down using water. The colour is then stripped from these materials using an eco-friendly bleach and after any synthetic fibres are removed from the mix, the slurry-like mixture is dried and the excess water is extracted, leaving behind a sheet of Circulose. This sheet is then made into viscose fibre which is combined with cotton and woven into new fabrics.

Circular Park
Omer Ahmed, CEO of Artistic Milliners also announced plans for his company’s new 70,000 square-foot Circular Park in Karachi, Pakistan, at Kingpins24 Flash.

Once complete, this will add three million square metres of additional denim capacity a month to the company’s production and take its total recycled output to a monthly five million metres.
Ahmed observed that there is currently a lack of sustainable fibres that are readily available to use for denim production at scale.

“Organic cotton is too expensive, and in my opinion always will be,” he said. “Cottonised hemp is also not cheap and it’s hard to mix with cotton, while the new regenerated cellulose fibres that are now emerging are promising, but currently in short supply. Recycled polyester is meanwhile still based on petroleum resources which we want to move away from. As a consequence, there are only a few other options for us as a manufacturer and this new project will help us minimise our own waste while significantly lowering our carbon footprint.”

Other Monforts denim customers to introduce cotton fibre recycling operations at their plants recently include AGI Denim, Bossa and Soorty.

Vertical savings
Refresh is the name of the latest collection from AGI Denim – reflecting the company’s significant reduction in water consumption.

The company has just opened new fibre spinning and denim mills at its complex in Karachi, Pakistan.

“Over the years we’ve gone through a series of backward integration steps to become fully vertical,” said AGI Denim executive director Ahmed Javed, at Kingpins24 Flash. “In our latest expansion, we revisited every step of the production processes in order to make resource savings.”

Innovations have included the installation of proprietary robotics for garment finishing, but the most attention has been paid to water savings.

“Pakistan is one of the largest cotton-producing companies in the world and we’re fortunate that the type of cotton that is grown here is well suited to denim production and also helps us lower our carbon footprint, with everything done in close proximity,” Javed said. “In the lifecycle of a pair of denim jeans, however, cotton fibre production contributes 68% of water consumption. While we cannot control how much water cotton needs for it to grow, we can rethink the way we use it in our factory.”

Refresh-branded denims are washed from 100% recycled water as a result of the company’s new wastewater treatment plant, which puts production wastewater through a series of steps beginning with equalisation, followed by aeration and concluding with sedimentation. The water travels through filtration and ultrafiltration systems before being subjected to an activated carbon system and finally a reverse osmosis system to reduce any dissolved salts.

AGI now recycles 4.4 million gallons of water each month – enough to wash a million pairs of jeans.

Sustainable
Monforts has a leading position in the field of denim finishing with its well proven Thermex continuous dyeing systems, Montex stenter dryers and other lines for resource-efficient and economical processing.

“Our denim partners are constantly setting themselves new goals in respect of sustainable production – and more importantly, achieving them,” says Hans Wroblowski, Monforts Head of Denim. “We work closely with them with the aim of constantly optimising processing parameters and achieving further savings in energy, water and raw materials throughout the dyeing and finishing stages of production.”

The latest Monforts innovation for denim is the CYD yarn dyeing system. This technology is based on the effective and established dyeing process for denim fabrics that is now being applied for yarn dyeing. The CYD system integrates new functions and processes into the weaving preparation processes to increase quality, flexibility, economic viability and productivity. A full CYD line is now available for trials at the company’s Advanced Technology Centre in Mönchengladbach, Germany.”
