Each year, the JEC Composites Innovation Awards recognize innovative and creative projects that demonstrate the full potential of composite materials. With the help of a development team from 12 companies and research institutions, TechnoCarbon Technologies GbR successfully submitted its innovative DACCUSS building element for house walls made of Carbon Fiber Stone.

Carbon Fiber Stone is a building material made of natural rocks and bio-based carbon fibers. It serves as an environmentally friendly replacement for CO2-intensive concrete in the construction industry. While conventional concrete walls release large amounts of CO2 during production, the DACCUS building element binds 59 kg of CO2 per square meter and therefore has a negative carbon footprint. In addition, the panels weigh only one-third of equivalent reinforced concrete house walls.

Each DACCUS element consists of several high-strength natural stone slabs made from magmatic rock. Inside the construction are bio-based carbon fibers, which the DITF Denkendorf is working intensively to develop. They form the stiffening element that enables the high strength of the construction elements and, in turn, contribute to the negative CO2 balance. The layer between the natural rock slabs is filled with carbon-negative biochar granulate, which is responsible for the insulation of the building element. The mineral sawdust from the cut rock slabs can be used as a soil amendment and serves as a binder for free CO2 from the atmosphere. The strict focus on processes and materials that actively bind CO2 has made it possible to produce a building material with a negative CO2 balance.

Autoneum’s components thus offer a significantly more sustainable alternative to the composite or thermoset resin panels commonly used in trucks today, which are difficult to recycle. Thanks to the unique material composition of Propylat PET, they contribute to optimized acoustic and thermal management.

With the establishment of a dedicated Business Unit Commercial Vehicles at the beginning of 2024, Autoneum has set the course for further sustainable and profitable growth in this market segment on a global scale. Manufacturers of medium and heavy trucks as well as agricultural vehicles thus benefit not only from Autoneum’s existing production footprint and comprehensive product and technology portfolio, but also from the Company’s longstanding experience in the development and manufacturing of environmentally friendly monomaterials. Components such as the new polyester-based side and rear wall panels support customers in improving the environmental performance of commercial vehicles and are therefore an important step towards a circular economy also in this vehicle segment.

The carrier material of Autoneum’s sustainable trim components consists of 100 percent polyester. Thanks to the high content of recycled fibers and the excellent end-of-life recyclability of Propylat PET, the side and rear wall panels from Autoneum are considerably more environmentally friendly than the composite or thermoset resin alternatives commonly used in trucks today. Furthermore, additional components can be welded onto the material without the use of adhesives or other chemicals, which further increases the products’ recyclability at the end of their service life. Due to the unique material composition of Propylat PET, the components also improve the acoustic and thermal insulation of the vehicle interior and are characterized by minimal emission of volatile organic compounds as well as low odor. In addition, Autoneum continues to invest in the develop-ment of monomaterial components for commercial vehicles, where both the carrier material and the aesthetic surface are made entirely of polyester, thus further advancing the transition to a sustaina-ble circular economy.

SGL Carbon: Business Report 3Q

Weak demand in some of their customer markets is increasingly hindering SGL Carbon's sales growth. After nine months in 2024, SGL Carbon generated sales of €781.9 million, which was slightly below the prior-year level at minus 4.8% (9M 2023: €821.7 million). Adjusted for currency and structural effects, Group sales decreased by 3.6%. Adjusted EBITDA, an important key figure for the Group, remained at a comparable level of €127.6 million in the reporting period (9M 2023: €130.0 million). Despite the slight decrease in sales, the adjusted EBITDA margin improved from 15.4% in Q1 and 16.7% in Q2 to 16.9% in Q3 and amounted to 16.3% after nine months (9M 2023: 15.8%). The reasons for the improved adjusted EBITDA margin are, in particular, product mix effects in the Graphite Solutions and Process Technology business units. By contrast, the ongoing weakness in demand and the associated price pressure for carbon and textile fiber products in the Carbon Fibers business unit continued to weigh on the Group's sales and earnings development.

Weak demand in some of their customer markets is increasingly hindering SGL Carbon's sales growth. After nine months in 2024, SGL Carbon generated sales of €781.9 million, which was slightly below the prior-year level at minus 4.8% (9M 2023: €821.7 million). Adjusted for currency and structural effects, Group sales decreased by 3.6%. Adjusted EBITDA, an important key figure for the Group, remained at a comparable level of €127.6 million in the reporting period (9M 2023: €130.0 million). Despite the slight decrease in sales, the adjusted EBITDA margin improved from 15.4% in Q1 and 16.7% in Q2 to 16.9% in Q3 and amounted to 16.3% after nine months (9M 2023: 15.8%). The reasons for the improved adjusted EBITDA margin are, in particular, product mix effects in the Graphite Solutions and Process Technology business units. By contrast, the ongoing weakness in demand and the associated price pressure for carbon and textile fiber products in the Carbon Fibers business unit continued to weigh on the Group's sales and earnings development.

“Even with our diversified product portfolio, we can no longer completely withdraw from the generally weak economic environment. In addition, there was a decline in demand for specialty graphite products for the semiconductor industry in the third quarter. In particular, our products for the manufacture of silicon carbide-based semiconductors are suffering from the restrained demand for electric vehicles on the customer side,” explains CEO Dr. Torsten Derr. “While the last 18 months were characterized by enormous demand for silicon carbide semiconductors and insufficient production capacities, the market has cooled down significantly. Due to a lack of demand from the automotive industry, our semiconductor customers have significantly reduced order volumes. We do not expect to see a significant upturn in demand for our specialty graphite products until the sales figures for electric vehicles pick up again.”

Based on the adjusted EBITDA of €127.6 million and taking into account depreciation and amortization of €41.0 million (9M 2023: €43.3 million) and one-off effects as well as non-recurring items of minus €18.3 million (9M 2023: minus €47.2 million), EBIT after nine months of 2024 will be €68.3 million (9M 2023: €39.5 million). The one-off effects and non-recurring items result, among other things, from the restructuring measures at Carbon Fibers and the Battery Solutions business line as well as from expenses for a strategy project. When comparing with the previous year, it should be noted that the first nine months of 2023 were disproportionately affected by an impairment loss on the assets of Carbon Fibers (€44.7 million).

Development of the business units
The Carbon Fibers business unit's sales for the first nine months of 2024 amounted to €157.1 million, significantly below the figure of €179.6 million for the prior-year period. The decline is due in particular to the continued weak demand from the wind industry and to the increasing competitive pressure resulting from global overcapacities for carbon and textile fibers.

Idle production capacities and the associated lack of fixed cost absorption as well as declining margins for commodity products led to a further deterioration in the adjusted EBITDA of the Carbon Fibers. The adjusted EBITDA of the Carbon Fibers business unit fell to minus €7.9 million in the first nine months of 2024 (9M 2023: €3.2 million). It should be noted that the adjusted EBITDA of the Carbon Fibers business unit includes an earnings contribution of €11.6 million from the joint venture BSCCB, which is accounted for At-Equity (9M 2023: €14.1 million). Excluding this contribution from the At-Equity accounted BSCCB, the adjusted EBITDA of Carbon Fibers would have been minus €19.6 million (9M 2023: minus €10.5 million).

SGL Carbon assumes that demand for carbon fibers will not recover in the coming months and that the realizable prices for these products will remain at a low level beyond 2025. Therefore, SGL Carbon anticipates that the expected improvement in sales and earnings for the Carbon Fibers segment will be delayed and is revising its existing mid-term planning for this segment. Due to the expected deviation, an ad hoc impairment test is currently being carried out. This indicates a non-cash impairment charge of €60–80 million, which will be recognized in Q4 2024. The structured transaction process initiated for Carbon Fibers is still ongoing.

Sales in the Composite Solutions business unit amounted to €95.8 million in the first nine months of 2024, down 16.2% (9M 2023: €114.3 million). The decline is due in particular to the early termination of a project-related supply contract with an automotive customer. Furthermore, the lower sales figures for electric vehicles are also having an impact on Composite Solutions.

Adjusted EBITDA in Composite Solutions fell from €16.6 million in the prior-year period to €10.7 million (minus 35.5%), due in particular to lower volumes. The adjusted EBITDA margin weakened accordingly to 11.2% (9M 2023: 14.5%).

Outlook
Macroeconomic conditions, lower than expected sales volumes in some customer groups and price pressure for commodity products are increasingly hindering SGL Carbon's growth ambitions. Thomas Dippold, CFO of SGL Carbon, explains: “Due to the diverse and diversified industrial applications of our products and our strict cost management, we continue to expect to achieve our guidance for 2024 at the lower end of the range of €160–170 million. The coming months will not be easier. We need to prepare for a flat demand development in some of our sales markets.”

SGL Carbon SE: Impairment in the Carbon Fibers business unit

With the publication of the half-yearly figures for 2024, SGL Carbon already announced that the company expects to achieve its adjusted EBITDA guidance for fiscal year 2024 at the lower end of the range of €160 to 170 million. Based on the preliminary figures for the first nine months of the fiscal year 2024, SGL Carbon confirms this statement.

With the publication of the half-yearly figures for 2024, SGL Carbon already announced that the company expects to achieve its adjusted EBITDA guidance for fiscal year 2024 at the lower end of the range of €160 to 170 million. Based on the preliminary figures for the first nine months of the fiscal year 2024, SGL Carbon confirms this statement.

According to preliminary figures, Group sales of SGL Carbon for the first nine months of fiscal year 2024 decreased by 4.8% year on year to €781.9 million (9M 2023: €821.7 million). Preliminary adjusted EBITDA, on the other hand, remained at a comparable level to the prior-year period, at €127.6 million (9M 2023: €130.0 million). Despite the slight sales decline, the adjusted EBITDA margin improved to 16.3% after nine months in 2024 (9M 2023: 15.8%). The reasons for the improved adjusted EBITDA margin are, in particular, product mix effects in the Graphite Solutions and Process Technology business units. By contrast, the ongoing weakness in demand for carbon and textile fiber products in the Carbon Fibers business unit and the early termination of a customer contract at Composite Solutions weighed on the Group's sales and earnings development.

The business unit Carbon Fibers manufactures carbon and textile fibers for the wind and automotive industries as well as various industrial applications. As expected by the Company for the fiscal year 2024, demand for carbon fibers from the wind and automotive industries remains weak. In addition, there is increasing competitive and price pressure due to global overcapacity for both carbon fibers and textile fibers. The company does not expect demand to recover in the coming months and the realizable prices for these products will remain at a low level beyond 2025. Furthermore, SGL Carbon expects that the anticipated improvement in sales and earnings for the Carbon Fibers business unit will be delayed and is revising its existing medium-term planning for Carbon Fibers.

Due to the associated expected deviation an event-driven impairment test is currently being carried out. This indicates a non-cash impairment charge of €60–80 million, which will be recorded in the fourth quarter of 2024. The impairment relates exclusively to Carbon Fibers; the operating business of the other business units is not affected.

SGL Carbon's equity ratio after the impairment is approx. 40% (September 30, 2024: 43.3% according to preliminary figures).

The review of all strategic options for the Carbon Fibers business unit, which was announced by SGL Carbon on February 23, 2024, and has already begun, remains unaffected by the impairment and is currently continuing.

A complementary layering system ensures a uniform take-up speed and therefore gentle processing of the fiber material. This sophisticated weft tension compensation device is one of a whole series of tried and tested features of KARL MAYER multiaxial technology that have been integrated into the new machine. Other adopted solutions include the Fiber Chopping Unit, which allows glass fiber chips to be introduced into the laying process and thus cover more fields of application, and a single pin transport chain for a processing method with less waste.

Newly developed innovations also ensure even better performance, including the fixed layer system, which ensures high placement precision at all laying angles. Other equipment details with added value for the customer include a conveyor belt across the full working width, the walking needle system, which prevents the formation of lanes even with long stitch lengths, and the fitting of single compound needles, which can be changed efficiently.

Teijin Frontier: Breathable, UV-blocking polyester material

Teijin Frontier Co., Ltd., the Teijin Group’s fibers and products converting company, announced the development of a new, multifunctional and comfortable polyester material that combines high breathability and UV protection. This new product reproduces the structure of a traditional Japanese "Sudare" blind (bamboo blind), which allows breezes to pass through while blocking out sunlight.

As extremely high summer temperatures become increasingly common, Teijin Frontier developed this new polyester to meet market demands for materials with enhanced heat protection functions. Heat protection encompasses breathability, UV resistance and anti-stickiness. However, until now, breathability – achieved by gaps between fibers – and UV protection were thought to be mutually exclusive.

To solve this dilemma, the company created a structure with slit-shaped, highly breathable areas in either the warp or weft direction of the fabric. These three-dimensional gaps, similar to those in a bamboo blind, allow the material to deliver both excellent breathability and high UV blocking performance of 85 percent or more. The structure allows air permeability of 50㎤/㎠・s or more.

This new product also offers sustainability benefits through the incorporation of recycled polyester in part. Its structure and elastic fibers provide stretch performance, while an uneven surface caused by differences in thread shrinkage and its structure avoid stickiness. Moreover, to achieve the combination of functions, Teijin Frontier also adopt special high-shrinkage technology and dying finishing technology. This material offers potential for use in both fashion and casual clothing.

Teijin Frontier will begin promoting this product for the 2025 spring and summer fashion and casual clothing collections in Japan, aiming for sales of 250,000 meters in fiscal 2024 and 750,000 meters in fiscal 2027.

Lenzing: Sustainable geotextiles as glacier protection and jacket

The Lenzing Group has created an innovative concept that contributes to the sustainable protection of our glaciers while inspiring collective action for sustainable practices and a circular economy in the nonwovens and textile value chain. The concept, which was artistically staged by the Italian artist Michelangelo Pistoletto, was presented on March 21, 2024, as part of the International Day of Forests celebrations at the Palais des Nations, the headquarters of the United Nations Office at Geneva (UNOG).

The melting of glaciers is being severely impacted by global warming. Geotextiles are used to protect ice and snow. However, the nonwovens used for this are made of fossil-based fibers, which allow microplastics1 to enter the valley via streams and may enter the food chain through small organisms and animals. Nonwovens made from cellulosic LENZING™ fibers, which are biodegradable at the end of their life cycle and can be completely recycled, are the sustainable solution to this problem.

Nonwovens made from cellulosic LENZING™ fibers, which are biodegradable at the end of their life cycle and can be completely recycled, are the sustainable solution to this problem.

The covering of a small area with the new material made from LENZING™ fibers was tested for the first time during a field test on the Stubai Glacier. Four meters of ice were saved from melting. This was confirmed in a study conducted by the University of Innsbruck and the Austrian glacier lift operators on the Stubai Glacier in Tyrol (Austria). In 2023, the pilot project was successfully extended to all Austrian glaciers used by tourists.

Last year, the project was also awarded first place in the prestigious Swiss BIO TOP Awards for wood and material innovations.

Lenzing takes this innovation project as an opportunity to inspire collaborative action towards sustainable practices and circularity in the textile value chain. Together with a network of innovative partners, Lenzing is working on processing geotextiles into new textile fibers giving them a second life as a garment. The use of geotextiles is usually limited to two years, after which the nonwovens would be disposed of. In the first phase of the pilot project, the recycling of nonwovens made for geotextiles use has been successfully tested and a fashionable “Glacier Jacket” has been produced, showcasing that the recycling of geotextiles is viable. Next to Lenzing, the network includes Marchi & Fildi Spa, a specialist in the field of mechanical recycling, the denim fabric manufacturer Candiani Denim and the fashion studio Blue of a Kind.

Biocarrier for green roofs
Freudenberg is showcasing a sustainable carrier material for green roofs on urban buildings at the trade fair. The carrier is made from polylactide, i.e. from renewable resources. When filled with soil, it provides a strong foothold to root systems, enabling the growth of lightweight sedum blankets that can be rolled out to provide instant green roofs. These roofs not only help counter urban heat, they also improve stormwater management and regulate indoor temperatures.

From textile waste to padding
The company extended its circular thermal wadding product range with the release of comfortemp® HO 80xR circular, a wadding made from 70 percent recycled polyamide from discarded fishing nets, carpet flooring and industrial plastic. Because polyamide 6, also known as nylon, retains its performance characteristics after multiple recycling processes, the fibers can be used again and again to manufacture performance sporting apparel, leisurewear and luxury garments.

Packaging solutions with various sustainability benefits
Freudenberg is also showcasing products for sustainable packaging and filtration solutions. The long-lasting Evolon® technical packaging series is a substitute for disposable packaging used in the transport of sensitive industrial items such as automotive parts. The material is made from up to 85 percent recycled PET. A further highlight at Techtextil are Freudenberg’s fully bio-based solutions for manufacturing dessicant bags.

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.

New sustainability label Autoneum Blue

With its new sustainability label Autoneum Blue, Autoneum combines the use of recycled materials with protecting the oceans and social responsibility. Autoneum Blue is a continuation of the LABEL blue by Borgers®, which was originally launched by Borgers Automotive. Following the acquisition of the German automotive supplier in April 2023, Autoneum has now fully integrated the label into its sustainable product portfolio.

Autoneum Blue is a continuation of the LABEL blue by Borgers®, which was originally launched by Borgers Automotive. Following the acquisition of the German automotive supplier in April 2023, Autoneum has now fully integrated the label into its sustainable product portfolio.

Marine pollution has reached alarming levels in recent decades, with plastic contamination posing one of the most harmful threats to the health of the world’s largest ecosystem. In light of ever-stricter legal requirements for the environmental performance of vehicles, especially regarding the recycled content of components and their end-of-life recyclability, the reduction and recycling of plastics is also one of the key challenges for the automotive industry. Autoneum Pure, the Company’s sustainability label for technologies with an excellent sustainability performance throughout the product life cycle, is already successfully helping customers to tackle these challenges. With Autoneum Blue, Autoneum is now expanding its sustainable product portfolio with a label for components that combine the use of recycled material with protecting the oceans and social responsibility.

In order to qualify for the Autoneum Blue label, components must be based on materials that consist of at least 30% recycled PET that was collected from coastal areas within a 50-kilometer range of the water. These credentials mean the products make an important contribution to preventing plastic pollution in the oceans. In addition, the process of collecting the PET bottles must be socially respon-sible and comply with human rights, and traceable procurement of the bottle flakes must be guaran-teed. Autoneum Blue thus complements the Company’s strategic target to continuously reduce water consumption in all areas of its operations with an additional focus on preventing plastic pollution of the oceans.

Autoneum currently offers selected wheelhouse outer liners, needlepunch carpets and trunk side trim under the Blue label. In principle, however, the label could be extended to any product based on Autoneum technologies that feature recycled polyester fibers. As an addition to Autoneum’s existing fully recyclable monomaterial polyester constructions, which are characterized by waste-free production and have a significantly lower carbon footprint compared to products made from virgin fibers, Autoneum Blue presents another example of the Company’s ongoing efforts and continuous strides towards a sustainable circular economy.

Hologenix: CELLIANT® as a printed coating

Hologenix has announced that its flagship product CELLIANT® infrared (IR) technology, a natural blend of IR-generating bioceramic minerals, is now more widely available from the company as a printed coating, expanding the uses of the technology and increasing the number of prospective partners. The innovation has already been named a Selection in the Fibers & Insulations Category of the ISPO Textrends Awards just last month.

Traditionally, CELLIANT has been embedded directly into fibers and yarns. However, for its print applications, CELLIANT fine mineral powder can be easily added directly onto the surface of all different fabric types. The company is particularly energized about how this expands the array of sustainable offerings that CELLIANT can be incorporated into, and is looking forward to partnering with brands to print CELLIANT on their ecofriendly fabrics. CELLIANT Print may be a cost-effective alternative to in-yarn solutions and allows for a more efficient supply chain.

fabrics or to a new fabric to create a variety of different product applications. For brands who are seeking a smaller pattern roller for apparel, orthopedic products or other close-to-skin projects, CELLIANT Print can accommodate this. There is also a larger pattern roller for bedding and larger-scale applications. As long as the print covers 80% of the fabric’s surface, the design possibilities for the print itself are virtually endless. CELLIANT Print has undergone mechanical testing for wash tests and can be confirmed to last the useful life of the product, for 50+ washes.

By applying CELLIANT Print directly onto the fabric, brand partners are able to use CELLIANT with a higher loading of bioceramic minerals than what would otherwise be possible with an in-yarn solution. This makes it ideal for recovery and performance purposes. In fact, an example of a CELLIANT Print application on kinesiology tape, KT Tape® PRO Oxygen™ was launched in April to great success.

In addition, the fully recyclable technology variant Propylat PET is now part of the sustainability label Autoneum Pure.

The ongoing electrification of mobility as well as increasingly strict regulatory requirements for vehicle performance in terms of sustainability and acoustics are presenting new challenges to car manufacturers worldwide. With Propylat, Autoneum now offers another lightweight, fiber-based and versatile technology whose sound-insulating and -absorbing properties as well as high content of recycled materials help customers address these challenges. Propylat-based products not only contribute to reducing pass-by noise and improving driver comfort, but they are also up to 50 percent lighter than equivalent plastic alternatives; this results in a lower vehicle weight and, consequently, less fuel and energy consumption as well as lower CO2 emissions.

Autoneum's innovative Propylat technology consists of a mixture of recycled synthetic and natural fibers – the latter include cotton, jute, flax or hemp, for example – that are consolidated using thermoplastic binding fibers without adding any further chemical binders. Thanks to the flexible fiber composition and the variable density and thickness of the porous material, the properties of the respective Propylat variant, for example with regards to acoustic performance, can be tailored to individual customer requirements. This allows for a versatile application of the technology in a variety of interior and exterior components such as wheelhouse outer liners, trunk trim, underbody systems and carpets. For instance, Propylat-based wheelhouse outer liners significantly reduce rolling noise both inside and outside the vehicle while at the same time offering optimum protection against stone chipping and spray water.

In terms of sustainability, Propylat always contains a high proportion of recycled fibers – up to 100% in some variants – and can be manufactured with zero waste. Thanks to the full vertical integration of Propylat and Autoneum’s extensive expertise in recycling processes, the technology also contributes to a further significant reduction in production waste. Moreover, the Propylat PET technology variant, which consists of 100% PET, of which up to 70% are recycled fibers, is fully recyclable at the end of product life. For this reason, Propylat PET has been selected for Autoneum Pure – the Company’s sustainability label for technologies with excellent environmental performance throughout the product life cycle – where it will replace the current Mono-Liner technology going forward.

Propylat-based components are currently available in Europe, North America and China.

DITF: Lignin coating for Geotextiles

Textiles are a given in civil engineering: they stabilize water protection dams, prevent runoff containing pollutants from landfills, facilitate the revegetation of slopes at risk of erosion, and even make asphalt layers of roads thinner. Until now, textiles made of highly resistant synthetic fibers have been used for this purpose, which have a very long lifetime. For some applications, however, it would not only be sufficient but even desirable for the auxiliary textile to degrade in the soil when it has done its job. Environmentally friendly natural fibers, on the other hand, often decompose too quickly. The German Institutes of Textile and Fiber Research Denkendorf (DITF) are developing a bio-based protective coating that extends their service life.

For some applications, however, it would not only be sufficient but even desirable for the auxiliary textile to degrade in the soil when it has done its job. Environmentally friendly natural fibers, on the other hand, often decompose too quickly. The German Institutes of Textile and Fiber Research Denkendorf (DITF) are developing a bio-based protective coating that extends their service life.

Depending on humidity and temperature, natural fiber materials can degrade in the soil in a matter of months or even a few days. In order to significantly extend the degradation time and make them suitable for geotextiles, the Denkendorf team researches a protective coating. This coating, based on lignin, is itself biodegradable and does not generate microplastics in the soil. Lignin is indeed biodegradable, but this degradation takes a very long time in nature.

Together with cellulose, Lignin forms the building materials for wood and is the "glue" in wood that holds this composite material together. In paper production, usually only the cellulose is used, so lignin is produced in large quantities as a waste material. So-called kraft lignin remains as a fusible material. Textile production can deal well with thermoplastic materials. All in all, this is a good prerequisite for taking a closer look at lignin as a protective coating for geotextiles.

Lignin is brittle by nature. Therefore, it is necessary to blend the kraft lignin with softer biomaterials. These new biopolymer compounds of brittle kraft lignin and softer biopolymers were applied to yarns and textile surfaces in the research project via adapted coating systems. For this purpose, for example, cotton yarns were coated with lignin at different application rates and evaluated. Biodegradation testing was carried out using soil burial tests both in a climatic chamber with temperature and humidity defined precisely according to the standard and outdoors under real environmental conditions. With positive results: the service life of textiles made of natural fibers can be extended by many factors with a lignin coating: The thicker the protective coating, the longer the protection lasts. In the outdoor tests, the lignin coating was still completely intact even after about 160 days of burial.

Textile materials coated with lignin enable sustainable applications. For example, they have an adjustable and sufficiently long service life for certain geotextile applications. In addition, they are still biodegradable and can replace previously used synthetic materials in some applications, such as revegetation of trench and stream banks.

Thus, lignin-coated textiles have the potential to significantly reduce the carbon footprint: They reduce dependence on petroleum-based products and avoid the formation of microplastics in the soil.

Further research is needed to establish lignin, which was previously a waste material, as a new valuable material in industrial manufacturing processes in the textile industry.

The research work was supported by the Baden-Württemberg Ministry of Food, Rural Areas and Consumer Protection as part of the Baden-Württemberg State Strategy for a Sustainable Bioeconomy.
