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.

2024 outlook
Across its product portfolio, Solvay expects current demand levels to continue over the next few months and, as such, expects H1 2024 volumes to be broadly in line with H2 2023. At this point, there is little visibility on the second half of the year, however there are signs that the trend in the second half could improve. Solvay expects Soda Ash prices over FY 2024 to be lower than FY 2023, consistent with the current market environment, which will affect the business margin in 2024. Pricing trends across Solvay’s other businesses are forecasted to be more resilient year on year.

Lower energy and raw materials prices should offset some of the negative pressure on the topline. More importantly, Solvay has started to implement cost savings initiatives that will start to deliver results in 2024.

For full year 2024, Solvay expects an organic growth of the underlying EBITDA by -10% to -20% versus a high comparison base in 2023, especially in H1. This translates into a range of €925 million to €1,040 million at a 1.10 EUR/USD exchange rate.

The organic growth of the underlying EBITDA is calculated from a 2023 restated figure of €1,154 million (vs a reported figure of €1,246 million).

Free cash flow to Solvay shareholders from continuing operations is expected to be greater than €260 million, in line with the cash usage prioritization presented during the Capital Market Day in November 2023. It is supported by Solvay’s ability to manage its capex and working capital to ensure the financing of its businesses and the payment of dividends while keeping the strength of its balance sheet intact.

Solvay remains committed to implement its strategic roadmap and reconfirms its 2028 targets as communicated at the Capital Markets Day of November 2023.

Textiles for technical applications often derive their special function via the application of coatings. This way, textiles become, for example wind and water proof or more resistant to abrasion. Usually, petroleum-based substances such as polyacrylates or polyurethanes are used. However, these consume exhaustible resources and the materials can end up in the environment if handled improperly. Therefore, the German Institutes of Textile and Fiber Research Denkendorf (DITF) are researching materials from renewable sources that are recyclable and do not pollute the environment after use. Polymers that can be produced from bacteria are here of particular interest.

These biopolymers have the advantage that they can be produced in anything from small laboratory reactors to large production plants. The most promising biopolymers include polysaccharides, polyamides from amino acids and polyesters such as polylactic acid or polyhydroxyalkanoates (PHAs), all of which are derived from renewable raw materials. PHAs is an umbrella term for a group of biotechnologically produced polyesters. The main difference between these polyesters is the number of carbon atoms in the repeat unit. To date, they have mainly been investigated for medical applications. As PHAs products are increasingly available on the market, coatings made from PHAs may also be increasingly used in technical applications in the future.

The bacteria from which the PHAs are obtained grow with the help of carbohydrates, fats and an increased CO₂ concentration and light with suitable wavelength.

The properties of PHA can be adapted by varying the structure of the repeat unit. This makes polyhydroxyalkanoates a particularly interesting class of compounds for technical textile coatings, which has hardly been investigated to date. Due to their water-repellent properties, which stem from their molecular structure, and their stable structure, polyhydroxyalkanoates have great potential for the production of water-repellent, mechanically resilient textiles, such as those in demand in the automotive sector and for outdoor clothing.

The DITF have already carried out successful research work in this area. Coatings on cotton yarns and fabrics made of cotton, polyamide and polyester showed smooth and quite good adhesion. The PHA types for the coating were both procured on the open market and produced by the research partner Fraunhofer IGB. It was shown that the molten polymer can be applied to cotton yarns by extrusion through a coating nozzle. The molten polymer was successfully coated onto fabric using a doctor blade. The length of the molecular side chain of the PHA plays an important role in the properties of the coated textile. Although PHAs with medium-length side chains are better suited to achieving low stiffness and a good textile handle, their wash resistance is low. PHAs with short side chains are suitable for achieving high wash and abrasion resistance, but the textile handle is somewhat stiffer.

The team is currently investigating how the properties of PHAs can be changed in order to achieve the desired resistance and textile properties in equal measure. There are also plans to formulate aqueous formulations for yarn and textile finishing. This will allow much thinner coatings to be applied to textiles than is possible with molten PHAs.

Other DITF research teams are investigating whether PHAs are also suitable for the production of fibers and nonwovens.

The Aachen-based start-up SA-Dynamics is developing sustainable, bio-based and biodegradable insulation materials made from aerogel fibres, thereby setting new standards in resource-saving construction. Dr Sascha Schriever (Institut für Textiltechnik ITA), Maximilian Mohr (ITA), Dr Jens Hofer (ITA Postdoc) and Dr Christian Schwotzer (Department for Industrial Furnaces and Heat Engineering IOB), who trained at RWTH Aachen University, were awarded first place in the KUER.NRW Business Plan Competition 2023 and prize money of €6,000.

SA-Dynamics relies on the impressive properties of aerogel fibres: they have excellent insulating properties, are lightweight, durable, robust, versatile and can be processed very well on conventional textile machines thanks to their flexibility. This makes them comparable to polystyrene, but still sustainable, as SA Dynamics uses bio-based and biodegradable raw materials.

"We can revolutionise the construction world with bio-based aerogel fibres," explains ITA founder Dr Sascha Schriever proudly. "If all insulation materials in construction are converted to bio-based aerogel fibres, all builders can realise their dream of a sustainable house."

SA Dynamics has come a good deal closer to its founding goal by winning the KUER.NRW 2023 business plan competition. The spin-off from Institut für Textiltechnik (ITA) and Department for Industrial Furnaces and Heat Engineering (IOB) at RWTH Aachen University is scheduled for spring 2025.

A lot of waste is generated in the trade fair and event industry. It makes sense to have furniture that can quickly be dismantled and stored to save space - or simply disposed of and recycled. Paper is the ideal raw material here: locally available and renewable. It also has an established recycling process. The German Institutes of Textile and Fiber Research (DITF) and their project partners have jointly developed a recycling-friendly modular system for trade fair furniture. The "PapierEvents" project was funded by the German Federal Environmental Foundation (DBU).

Once the paper has been brought into yarn form, it can be processed into a wide variety of basic elements using the structure winding process, creating a completely new design language.

The unusual look is created in the structure winding process. In this technology developed at the DITF, the yarn is deposited precisely on a rotating mandrel. This enables high process speeds and a high degree of automation. After the winding process, the individual yarns are fixed, creating a self-supporting component. A starch-based adhesive, which is also made from renewable and degradable raw materials, was used in the project for the fixation.

The recyclability of all the basic elements developed in the project was investigated and confirmed. For this purpose the research colleagues at the project partner from the Department of Paper Production and Mechanical Process Engineering at TU Darmstadt (PMV) used the CEPI method, a new standard test procedure from the Confederation of European Paper Industries.

Sensor and lighting functions were also implemented in a recycling-friendly manner. The paper sensor yarns are integrated into the components and detect contact.

Also, a modular system for trade fair and event furniture was developed. The furniture is lightweight and modular. For example, the total weight of the counter shown is well under ten kilograms and individual parts can easily be shipped in standard packages. All parts can be used several times, making them suitable for campaigns lasting several weeks.

A counter, a customer stopper in DIN A1 format and a pyramid-shaped stand were used as demonstrators. The research work of the DITF (textile technology) and PMV (paper processing) was supplemented by other partners: GarnTec GmbH developed the paper yarns used, the industrial designers from quintessence design provided important suggestions for the visual and functional design of the elements and connectors and the event agency Rödig GmbH evaluated the ideas and concepts in terms of usability in practical use.

ITMF (International Textile Manufacturer Federation) has published its International Textile Industry Statistics (ITIS) on productive capacity and raw materials consumption in the short-staple organized (spinning mill-) sector in virtually all textile-producing countries in the world.

The global number of installed short-staple spindles has grown from 225 million units in 2021 to 227 million units in 2022. The number of installed open-end rotors increased from 8.3 million in 2021 to 9.5 million in 2022. This constitutes the strongest growth ever recorded in this market with investment disproportionally targeting Asia. The number of installed air-jet spindles continued to increase in all regions in 2022.

The substitution between shuttle and shuttle-less looms continued in 2022. The number of installed shuttle-less looms increased from 1.72 million in 2021 to 1.85 in 2022 while installed shuttle looms reached 952 thousand. Total raw material consumption in the short-staple organized sector slightly decreased from 45,6 million tons in 2021 to 44,26 million tons in 2022. Consumption of raw cotton and synthetic short-staple fibers decreased by -2.5% and -0.7%, respectively. Consumption of cellulosic short-staple fibers increased by 2.5%.

CARBIOS, a pioneer in the development and industrialization of biological technologies to reinvent the life cycle of plastic and textiles, has received an initial payment of €1.2 million from the French Agency for Ecological Transition (ADEME) for the OPTI-ZYME research project, carried out in partnership with INRAE2, INSA3 and CNRS4 via the TWB5 joint service and TBI6 research units, a project co-funded by the French State as part of France 2030 operated by ADEME. With CARBIOS' aim to optimize and continuously improve its unique enzymatic PET depolymerization technology, the 4-year7 OPTI-ZYME project aims to investigate the scientific and technical levers for improving the competitiveness of the process, optimizing the necessary investments and reducing its environmental footprint.

This collaborative R&D program focuses on the technical and economic optimization of process stages, while preserving the quality of the monomers obtained. These optimizations, new developments and the exploration of innovative solutions should enhance the technology's flexibility with regards to incoming waste. Raw materials could come from different sources that are currently rarely or not recycled, notably food trays and textiles, or a mix of incoming materials. It also aims to limit input and water consumption, as well as regenerate or reduce co-products and ultimate residual waste. Finally, it seeks to support enzyme optimization to maximize the process’ economic profitability and competitiveness.

The project therefore aims to achieve an overall improvement in performance, combining efficiency, quality and environmental sustainability, to benefit the Longlaville plant which is currently under construction, and future licensed plants.

In May 2023, CARBIOS, the project leader and coordinator, announced that it had been awarded a total of €11.4M in funding by the French State as part of France 2030, operated by ADEME, including €8.2M directly for CARBIOS (€3.2M in grants and €5M in repayable advances) and €3.2M for its academic partners INRAE, INSA and CNRS (via the TWB mixed service and TBI research units). This funding, which is made up of grants and repayable advances, will be paid out in several instalments over the course of the project, including an initial instalment of 15%, equivalent to €1.2 million, received by CARBIOS on 5 December 2023. The first Monitoring Committee with ADEME for the first key stage of the project will be held in February 2024 to validate the granting of the second instalment of funding.

This project 2282D0513-A is funded by the French State as part of France 2030 operated by ADEME.
