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.

CARBIOS will be particularly involved in the association's project to set up a working group dedicated to the development of a "fiber-to-fiber" industry, one of Paris Good Fashion's top priorities over the next five years. While only 1% of textiles are currently recycled fiber-to-fiber (circular), this working group will identify levers for significantly increasing the share of recycled fibers in the industry.  Polyester currently follows a linear model from which we need to break out: virgin polyester is made from petroleum, and recycled polyester from PET bottles. After use, most of these products end their lives in landfill or incineration. A circular, "fiber-to-fiber" industry will give new life to textiles and reduce the environmental impact associated to their end-of-life management.

SGL Carbon achieves annual targets for 2023

  • Three out of four business units with record sales and results
  • Carbon Fibers business weighs on the Group's profitability
  • Group sales of €1,089.1 million (-4.1%) and adjusted EBITDA of €168.4 million (-2.5%) in a difficult market environment
  • Sales and earnings forecast for 2023 achieved despite drop in demand from key market
  • 2024 further capacity expansion in graphite components for silicon carbide-based semiconductors

In fiscal year 2023, SGL Carbon achieved the sales and earnings targets set at the beginning of the year despite the drop in demand from the important wind market and an increasingly challenging economic environment. Group sales decreased slightly by €46.8 million (minus 4.1%) to €1,089.1 million (previous year: €1,135.9 million). At € 168.4 million, adjusted EBITDA, a key performance indicator for the Group, was also down slightly (minus 2.5%) compared to the previous year (€172.8 million) but was clearly within the forecast range for 2023 of €160 to 180 million.

While the positive sales development of the Graphite Solutions (+€53.5 million to €565.7 million), Process Technology (+€21.6 million to €127.9 million) and Composite Solutions (+€0.8 million to €153.9 million) business units had a positive effect, the Carbon Fibers business unit had a negative impact on Group sales with a sales decline of €122.3 million to €224.9 million.

Outlook
The global economy will continue to face comparatively high interest rates and subdued growth prospects in 2024. Tighter financing conditions, weak trade growth and a decline in business and consumer confidence are also weighing on the economic outlook. In addition, heightened geopolitical tensions are contributing to increased uncertainty.

SGL Carbon expects different developments in our key sales markets in 2024. The most important sales and earnings driver will be demand for specialty graphite components for the semiconductor industry. In contrast, all indicators currently suggest that demand for carbon fibers for the wind industry will remain weak in 2024 and that the Carbon Fibers (CF) business unit will therefore continue to record operating losses. Even if demand picks up, SGL Carbon assumes that Carbon Fibers will require additional resources to make the most of market opportunities. With this in mind, teh company announced on February 23, 2024, that they are reviewing all strategic options for Carbon Fibers. These also include a possible partial or complete sale of the business unit.

SGL Carbon's sales forecast for the financial year 2024 takes all four operating business units into account, as the company is only at the beginning of evaluating the strategic options for CF. In line with the assumptions outlined, SGL Carbon is therefore expecting Group sales at the previous year's level (2023: €1,089.1 million).

In the earnings forecast, SGL Carbon has taken into account underutilization of production capacity in the Carbon Fibers business unit and the associated high idle capacity costs. The projected operating loss of CF will have a negative impact on the adjusted EBITDA of the SGL Carbon Group in 2024. Due to the expected positive development of Graphite Solutions, SGL Carbon anticipates an adjusted EBITDA of between €160 million and €170 million for fiscal year 2024, taking into account all four operating business units. Should the process of reviewing all strategic options for the CF business unit result in a sale, the forecast of adjusted EBITDA in 2024 would be between €180 - 190 million.

The Lightweight Construction Alliance BW is the central point of contact for all players in the field of lightweight construction in the State and acts in their interests at national and international level. Professor Markus Milwich from the German Institutes of Textile and Fiber Research Denkendorf (DITF) represents the agency.

The use of lightweight materials in combination with new production technologies will significantly reduce energy consumption in transportation, the manufacturing industry and the construction sector. Resources can be saved through the use of new materials. As a cross-functional technology, lightweight construction covers entire value chain from production and use to recycling and reuse.

The aim of the state government is to establish Baden-Württemberg as a leading provider of innovative lightweight construction technologies in order to strengthen the local economy and secure high-quality jobs.

Among others, the "Lightweight Construction Alliance Baden-Württemberg" will continue the nationally renowned "Lightweight Construction Day", which acts as an important source of inspiration for a wide range of lightweight construction topics among business and scientific community.

Professor Milwich, an expert with many years of experience and an excellent network beyond the State's borders, has been recruited for this task. In his role, Milwich also represents the state of Baden-Württemberg on the Strategy Advisory Board of the Lightweight Construction Initiative of the Federal Ministry for Economic Affairs and Climate Action, which supports the cross functional-technology and efficient transfer of knowledge between the various nationwide players in lightweight construction and serves as a central point of contact for entrepreneurs nationwide for all relevant questions.

From 2005 to 2020, Professor Milwich headed the Composite Technology research at the DITF, which was integrated into the Competence Center Polymers and Fiber Composites in 2020. He is also an honorary professor at Reutlingen University, where he teaches hybrid materials and composites. "Lightweight design is an essential aspect for sustainability, environmental and resource conservation. I always showcase this in research and teaching and now also as a representative of the lightweight construction community in Baden-Württemberg," emphasizes Professor Milwich.

  • Total proposed gross dividend of €2.43 per share, subject to shareholders’ approval during the next Ordinary General Meeting of May 28, 2024.
  • Solvay continues to reduce its GHG emissions (-19% vs 2021, scope 1 and 2).
  • 2024 Outlook: Organic growth of the underlying EBITDA of -10% to -20% compared to restated 2023; Free cash flow of minimum €260 million

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.

DITF: Modernized spinning plant for sustainable and functional fibres

The German Institutes of Textile and Fiber Research Denkendorf (DITF) have modernized and expanded their melt spinning pilot plant with support from the State of Baden-Württemberg. The new facility enables research into new spinning processes, fiber functionalization and sustainable fibers made from biodegradable and bio-based polymers.

In the field of melt spinning, the DITF are working on several pioneering research areas, for example the development of various fibers for medical implants or fibers made from polylactide, a sustainable bio-based polyester. Other focal points include the development of flame-retardant polyamides and their processing into fibers for carpet and automotive applications as well as the development of carbon fibers from melt-spun precursors. The development of a bio-based alternative to petroleum-based polyethylene terephthalate (PET) fibers into polyethylene furanoate (PEF) fibers is also new. Bicomponent spinning technology, in which the fibers can be produced from two different components, plays a particularly important role, too.

Bicomponent spinning technology, in which the fibers can be produced from two different components, plays a particularly important role, too.

Since polyamide (PA) and many other polymers were developed more than 85 years ago, various melt-spun fibers have revolutionized the textile world. In the field of technical textiles, they can have on a variety of functions: depending on their exact composition, they can for example be electrically conductive or luminescent. They can also show antimicrobial properties and be flame-retardant. They are suitable for lightweight construction, for medical applications or for insulating buildings.

In order to protect the environment and resources, the use of bio-based fibers will be increased in the future with a special focus on easy-to-recycle fibers. To this end, the DITF are conducting research into sustainable polyamides, polyesters and polyolefins as well as many other polymers. Many 'classic', that is, petroleum-based polymers cannot or only insufficiently be broken down into their components or recycled directly after use. An important goal of new research work is therefore to further establish systematic recycling methods to produce fibers of the highest possible quality.

For these forward-looking tasks, a bicomponent spinning plant from Oerlikon Neumag was set up and commissioned on an industrial scale at the DITF in January. The BCF process (bulk continuous filaments) allows special bundling, bulking and processing of the (multifilament) fibers. This process enables the large-scale synthesis of carpet yarns as well as staple fiber production, a unique feature in a public research institute. The system is supplemented by a so-called spinline rheometer. This allows a range of measurement-specific chemical and physical data to be recorded online and inline, which will contribute to a better understanding of fiber formation. In addition, a new compounder will be used for the development of functionalized polymers and for the energy-saving thermomechanical recycling of textile waste.

European composites market on the level of 2014

After a long phase of continuous growth, the composites market has seen strong fluctuations since 2018. In 2023, the overall market for composites in Europe fell by 8%.

The current mood on the markets in Germany and Europe is rather negative within the industry. The main drivers are the persistently high energy and raw material prices. Added to this are problems in logistics chains and a cautious consumer climate. A slowdown in global trade and uncertainties in the political arena are fueling the negative sentiment. Despite rising registration figures, the automotive industry, the most important application area for composites, has not yet returned to its pre-2020 volume. The construction industry, the second key application area, is currently in crisis. These factors have already caused the Eu-ropean composites production volume to fall significantly in recent years. There has now been another decline in Europe for 2023.

There has now been another decline in Europe for 2023.

Overall development of the composites market
The volume of the global composites market totalled 13 million tons in 2023. Compared to 2022, with a volume of 12.3 million tons, growth was around 5%. In comparison, the European composites production volume fell by 8% in 2023. The total European composites market thus comprises a volume of 2,559 kilotons (kt) after 2,781 kt in 2022.

The market is therefore declining and falling back to the level of 2014. Overall, market momentum in Europe was lower than in the global market. Europe's share of the global market is now around 20%.

As in previous years, development within Europe is not uniform. The differences are due to very different regional core markets, the high variability of the materi-als used, a wide range of different manufacturing processes and widely differing areas of application. Accordingly, there are different regional trends, especially with regard to the individual processes, although there were declines in all re-gions and for almost all processes in 2023. At almost 50% of the market volume, the transportation sector accounts for the largest share of total composites pro-duction in terms of volume. The next two largest areas are the electri-cal/electronics sector and applications in construction and infrastructure.

SGL Carbon: Review of options for Business Unit Carbon Fibers

SGL Carbon SE is currently evaluating various strategic options for the Business Unit Carbon Fibers (CF). These include a possible partial or complete divestment of the Business Unit. In a first step, potential interested parties shall be approached with the general data of the Business Unit to determine their interest in an acquisition. If there is sufficient interest, a structured transaction process will be carried out in a second step. Overall, a share of sales amounting to around € 179.6 million after nine months in 2023 (9M 2022: € 269.0 million) is therefore under review. The CF sales share corresponded to 21.9% of SGL Carbon's consolidated sales after nine months in 2023 (9M 2022: 31.5%). Adjusted EBITDA of the Business Unit excluding the result from joint ventures amounted to minus € 10,9 million after nine months in 2023 (9M 2022: € 27,9 million). Despite the operating loss of CF after nine months in 2023, SGL Carbon maintains its guidance for fiscal year 2023. This shows the positive development of the three other business units and the resilience of SGL Carbon's business model.

This shows the positive development of the three other business units and the resilience of SGL Carbon's business model.

Carbon Fibers manufactures textile, acrylic and carbon fibers as well as composite materials at seven locations in Europe and North America. Following the temporary drop in demand for carbon fibers from the important wind industry market, the Business Unit's sales and earnings fell significantly in the course of fiscal year 2023. Due to the importance of the wind industry for the European Green Deal, SGL Carbon and many experts assumed that the wind industry recovers quickly. Unfortunately, this is currently not the case. Even if demand picks up, the company assumes that Carbon Fibers will need additional resources to remain competitive in the international market environment and to exploit market opportunities in the best possible way. Against this background, SGL Carbon is reviewing all possibilities to support a positive further development of the Carbon Fibers Business Unit.

DITF: Biopolymers from bacteria protect technical textiles

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.

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.
