From the Sector

Lightweight design is a key enabler for addressing the energy transition and sustainable economy. Following the liquidation of the state agency Leichtbau BW GmbH, a consortium consisting of the Allianz Faserbasierter Werkstoffe Baden-Württtemberg (AFBW), the Leichtbauzentrum Baden-Württemberg (LBZ e.V. -BW) and Composites United Baden-Württemberg (CU BW) now represents the interests of the lightweight construction community in the State.

The Lightweight Design Agency for Baden-Württemberg is set up for this purpose on behalf of and with the support of the State. 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.

A major capacity expansion has been completed at AkzoNobel’s Powder Coatings site in Como, Italy, which will help secure supply to customers across Europe, Middle East and Africa (EMEA).

Four new manufacturing lines are now operational following the €21 million project – two of them dedicated to automotive primers and two to architectural coatings. New bonding equipment lines have also been added, ensuring that the products meet and exceed industry standards.

The extra capacity in Como has been installed in a renovated building where powder coatings were originally made – a sustainable reuse of an existing part of the site, which was established in 1992. The new lines also use recycled energy and are focused on meeting the highest standards in sustainable production, supporting the company’s ambition to reduce its carbon emissions by 50% by 2030.

AkzoNobel’s Como site is the company’s largest plant for producing powder coatings. It supplies products for market segments, such as home appliances, architecture, automotive, furniture and more.

The Fashion for Good museum in Amsterdam marks its 6 year journey with a special fashion exhibition focused on circularity, called What Goes Around Comes Around. Honing in on how circularity plays out in different circles of influence, the exhibition showcases inspirational displays that make tangible what a circular fashion industry will look like.

What Goes Around Comes Around pays homage to the extraordinary work of pioneering artists, innovators and designers working to shift the fashion industry with new solutions. The exhibition opens January 27, 2024 and will be open to the public for 5 months. It is the grand finale, as the Museum is closing its doors. As such it will be the Museum’s final call to collective action, which the fashion industry still so highly needs.

“We are highlighting three areas in What Goes Around Comes Around", explains curator Sophie Jager-van Duren at the Fashion for Good Museum. “First: new work by local artists Atelier Reservé and The Patchwork Family, design collectives working towards circularity, demonstrating what is happening right now. We are also showing looks from established designers BOTTER, Ronald van der Kemp and Marga Weimans, Yuima Nakazato and Nicole McLaughlin. Second, the community, with an installation for visitors to participate in, planting the seed that we need each other to change the fashion system. Lastly, the industry - honing in on examples of innovations and technologies. We invited designers to create new work with circular materials including Living Ink, MIRUM, Altmat and Biophilica.”

Today’s fashion industry is caught in a vicious cycle of ‘take-make-waste’ and this system has a growing negative impact on people and the planet. For instance, in Europe, the average consumer is responsible for 15 kilos of textile waste per year and these numbers are increasing. To address this, we need action from individuals, the industry and society alike to go from a linear take-make-waste model into one that is circular by design.

The Fashion for Good Museum is inviting anybody to come visit its final exhibition and learn from concrete examples, to understand the current state of the fashion industry, gain the tools for taking individual or collective action and be inspired by circular fashion available today.

Designing for circularity means designing without creating waste or pollution, as all materials are continually reused instead of discarded. A circular system is restorative and regenerative and reduces pressure on natural resources. The ultimate goal of the exhibition is to put circularity into practice, help people envision a circular economy based on community practices and empower visitors to take collective action, starting in the museum but extending to their homes and daily lives.

Through the exhibition and its public programme, which consists of interactive workshops and educational events, the museum functions as a community space where visitors are invited to learn, gain new perspectives and are exposed to inspiring examples, building the skills and knowledge to create positive change. The upcoming few months there are multiple events, educational toolkits and other opportunities to join us, all open for the public, keep an eye out on our website and social media channels for the latest updates.

The exhibition is open for the public from Saturday 27th of January until June 5th 2024, marking World Environment Day on June 5th as the final closing day of the museum.

Researchers at the ITA, the University of Bonn and Heimbach GmbH have developed a new method for removing oil spills from water surfaces in an energy-saving, cost-effective way and without the use of toxic substances. The method is made possible by a technical textile that is integrated into a floating container. A single small device can remove up to 4 liters of diesel within an hour. This corresponds to about 100 m2 of oil film on a water surface.
 
Despite the steady expansion of renewable energies, global oil production, oil consumption and the risk of oil pollution have increased steadily over the last two decades. In 2022, global oil production amounted to 4.4 billion tons! Accidents often occur during the extraction, transportation and use of oil, resulting in serious and sometimes irreversible environmental pollution and harm to humans.

There are various methods for removing this oil pollution from water surfaces. However, all methods have various shortcomings that make them difficult to use and, in particular, limit the removal of oil from inland waters.

For many technical applications, unexpected solutions come from the field of biology. Millions of years of evolution led to optimized surfaces of living organisms for their interaction with the environment. Solutions - often rather unfamiliar to materials scientists and difficult to accept. The long-time routine examination of around 20,000 different species showed that there is an almost infinite variety of structures and functionalities. Some species in particular stand out for their excellent oil adsorption properties. It was shown that, e.g., leaves of the floating fern Salvinia molesta, adsorb oil, separate it from water surfaces and transport it on their surfaces (Figure 1, see also the video of the phenomon.).

The observations inspired them to transfer the effect to technical textiles for separating oil and water. The result is a superhydrophobic spacer fabric that can be produced industrially and is therefore easily scalable.

The bio-inspired textile can be integrated into a device for oil-water separation. This entire device is called a Bionic Oil Adsorber (BOA). Figure 2: Cross-section of computer-aided (CAD) model of the Bionic Oil Adsorber. The scheme shows an oil film (red) on a water surface (light blue). In the floating cotainer(gray), the textile (orange) is fixed so that it is in contact with the oil film and the end protrudes into the container. The oil is adsorbed and transported by the BOA textile. As shown in the cross-section, it enters the contain-er, where it is released again and accumulates at the bottom of the container. See also the video regarding the oil absorption on the textile, source ITA).
 
Starting from the contamination in the form of an oil film on the water surface, the separation and collection process works according to the following steps:

• The BOA is introduced into the oil film.
• The oil is adsorbed by the textile and separated from the water at the same time.
• The oil is transported through the textile into the collection container.
• The oil drips from the textile into the collection container.
• The oil is collected until the container is emptied.

The advantage of this novel oil separation device is that no additional energy has to be applied to operate the BOA. The oil is separated from the surrounding water by the surface properties of the textile and transported through the textile driven solely by capillary forces, even against gravity. When it reaches the end of the textile in the collection container, the oil desorbs without any further external influence due to gravitational forces. With the current scale approximately 4 L of diesel can be separated from water by one device of the Bionic Oil Adsorber per hour.

• It seems unlikely that a functionalized knitted spacer textile is cheaper than a conventional nonwoven, like it is commonly used for oil sorbents. However, since it is a functional material, the costs must be related to the amount of oil removed. In this respect, if we compare the sales price of the BOA textile with the sales prices of various oil-binding nonwovens, the former is 5 to 13 times cheaper with 10 ct/L oil removed.
  Overall, the BOA device offers a cost-effective and sustainable method of oil-water separation in contrast to conventional cleaning methods due to the following advantages:
• No additional energy requirements, such as with oil skimmers, are necessary
• No toxic substances are introduced into the water body, such as with oil dispersants
• The textiles and equipment can be reused multiple times
• No waste remains inside the water body
• Inexpensive in terms of the amount of oil removed.
• The team of researchers from the ITA, the University of Bonn and Heimbach GmbH was able to prove that the novel biomimetic BOA technology is surprisingly efficient and sustainable for a self-controlled separation and automatic collection of oil films including their complete removal from the water. BOA can be asapted for open water application but also for the use in inland waters. Furthermore, it is promising, that the textile can be used in various related separation processes. The product is currently being further developed so that it can be launched on the market in 2-3 years.

Australia is one of the highest waste generators in the world, with over 7.6 million tonnes of food ending up in landfill each year, costing over $36.6 billion and producing 17.5 million tonnes of greenhouse gas.

Deakin’s partnership with Jet Technology through REACH will explore ways to transform industry-generated organic waste into new products like organic textiles and stock feed using a rapid composting system.

Jet Technology’s Environmental Recycling System (ERS) will build a circular economy by creating valuable products for a range of industry sectors.

Australia is continuing to generate more landfill each year. A new partnership between Deakin’s Recycling and Clean Energy Commercialisation Hub (REACH) and Japanese-based company Jet Technology aims to turn this around by repurposing organic waste and transforming it into new products.

Australia contributes more than 7.6 million tonnes of food to landfill annually, costing over $36.6 billion and producing 17.5 million tonnes of CO2.

Deakin University scientist Alfred Deakin Professor and Chair in Biotechnology Colin Barrow and his team from the Centre for Sustainable Bioproducts will work with Jet Technology to explore the possible reuses of organic waste using Jet Technology’s Environmental Recycling System (ERS). The project will focus on converting organic waste from the agriculture, dairy and fishery sectors by drastically shortening composting time so it can be used to make new products.

The four-year research project will be undertaken at the BioFactory at Deakin’s Waurn Ponds campus. It will initially focus on processing agricultural waste, converting apple pomace into a bioproduct for the textile industry. Apple pomace consists of the apple skin, pulp, seeds and stems left over from apple juice manufacturing. Its disposal in landfill can lead to greenhouse gas emissions and potential contamination of soil and groundwater.

If successful, it could lead to the establishment of a local multi-million-dollar bioeconomy where organisations such as councils, supermarkets and food and beverage businesses could cut costs while generating new revenue streams and job opportunities.

Deakin’s REACH initiative collaborates with progressive industry, government, and education partners to establish a multi-billion-dollar bioeconomy in Victoria and push the limits of technological innovation to deliver energy and recycling solutions that reduce landfill, fossil fuel emissions, and the devastating costs of global warming.

The priority of sweater manufacturers has always been to select ingredients and fibers that are soft, hypoallergenic, and of the finest quality to meet consumer expectations that their sweaters are comfortable yet durable and easy to care for. According to the recent Eastman consumer study of sweater lovers, the sweaters consumers want to add to their wardrobes are soft, comfortable, stylish, and versatile. However, consumers are very disappointed when their sweaters look and feel differently after wearing and washing. Choosing fibers and materials that deliver comfort, quality and ease of care is essential to win with consumers. Today, these are compounded by the ever-present consumer demand for a sustainable paradigm. The promise of Naia™ from Eastman is exactly to make sustainable style accessible to brands and inclusive for everyone through a portfolio of fibers that doesn’t compromise on quality, comfort, or garment care.

The results of soft and cozy blends between the versatile Naia™ fibers and other materials can be appreciated in the collections of Naadam and The Gap, which this year presented its third collection of men's sweaters blended with Naia™ and cotton. By using Naia™ blended knits in their collections, brands are not just choosing a sustainable ingredient, but also a certified and circular supply chain: all Naia™ cellulosic fiber is produced in a safe, closed-loop process where solvents are recycled back into the system for reuse. Eastman Naia™ partners with Textiles Genesis to provide track and trace solutions for brands. All Naia™ fibers are OEKO-TEX™ STANDARD 100 certified, ensuring no use of hazardous chemicals, and certified by TÜV AUSTRIA as biodegradable and compostable, also in the ocean, as supported by a recently published ocean degradation study conducted by Woods Hole Oceanographic Institution (WHOI).

Naia™ fibers are designed to create unlimited possibilities for uncompromising, sustainable style: among these, Naia™ Renew staple fiber permits to create eco-conscious blends that are supremely soft, quick-drying and consistently reduce pilling which are ideal for T-shirts, casual wear, sweaters, comfy pants and home textiles. Produced from 60% sustainably sourced wood pulp and 40% certified* recycled waste materials, Naia™ Renew creates the same top-quality fabrics as traditional Naia™ fibers, but with a reduced carbon footprint of around 35% — and it’s available at scale. The innovative cellulosic acetate materials can be blended with cotton, modal, merino wool, recycled polyester, or multiple content fancy yarns. Naia™ blended yarns deliver super softness for supreme wearing comfort in knitwear, and sweaters made with Naia™ Renew can have good dimensional stability and shape retention even after multiple washes. Versatile Naia™ denier sizes can be used in different yarn spinning processes, giving the yarn spinners freedom of creativity for trendy yarn designs perfect for year-round basic sweaters with good quality and a durable look. The unique cross section of Naia™ staple fibers enables designs that accommodate four seasons of wearing comfort.

Following their entry into the fibres and textiles sector, as announced at K 2022, recycling machine manufacturer EREMA launches the INTAREMA® FibrePro:IV - which has been specially developed for PET fibre-to-fibre recycling - at ITMA in Milan from June 8 to 14. Thanks to its especially gentle material preparation and efficient removal of spinning oils, the rPET produced can be reused in proportions of up to 100 percent for the production of very fine fibres.

PET is regarded as a key material for the production of synthetic fibres. Around two thirds of the total volume of PET goes into the production of PET fibres for the textile industry. This highlights the importance of high-quality recycling solutions for the circular economy. By combining proven INTAREMA® technology with a new IV optimiser, EREMA succeeds in processing shredded PET fibre materials heavily contaminated by spinning oils in such a way that the finest fibres can be produced again from the recycled pellets. The system, which now joins EREMA's machine portfolio as the INTAREMA® FibrePro:IV, is characterised by a longer residence time of the PET melt. This is an essential factor for achieving high quality recycled pellets, as it allows the spinning oils and other additives used to improve the handling of the fibres during manufacturing to be removed more efficiently than in conventional PET recycling processes. Following extrusion, by polycondensation the intrinsic viscosity (IV) of the PET melt is increased in the new IV optimiser and under high vacuum to the precise level that is needed for fibre production. "Including filtration the output quality that we achieve with this recycling process is so high that ultra-fine fibres of up to 2 dtex can be produced using these rPET pellets, with an rPET content of 100 percent," says Markus Huber-Lindinger, Managing Director at EREMA. Waste PET fibre from production processes can therefore be further processed into rPET filament fibre, carpet yarn and staple fibre.

While the focus of the fibre and textiles application is currently still on PET fibre recycling, EREMA is committed to driving forward the recycling of mixed fibre materials from classic textile recycling collection in a next project phase. In order to accelerate development work, the EREMA Group opened its own fibre test centre, where a cross-company team is working on recycling solutions for fibre-to-fibre applications. The centre also operates a fully equipped and variable industrial-scale recycling plant. It includes the peripheral technology required and is available to customers for trials.

Die CHT Group, a worldwide company for chemical specialties, has built a new production facility in Meghna Industrial Economic Zone (MIEZ), Narayanganj which was inaugurated on May 9th, 2023.

Martin Stangs, Regional Sales Manager APAC Auxiliaries at CHT says: “The long-term success story with RH Corporation now comes to an even higher level. In addition to the decade-long service provided by motivated colleagues of RH Corporation and constant visits by well-experienced CHT application field colleagues, CHT products will now be made available locally by our new production facility at CHT Bangladesh. This will further enhance our current high-end offer with in-time deliveries which are now possible. The well-known services provided by our up-to-date laboratory facility in Dhaka will continue to prevail. This is all supported by the profound analytical and technical equipment at CHT Germany as well as CHT Switzerland. Less water, less energy, less time, but still “fit-for-purpose performance”: these requirements are no strangers to us. In alignment with our CHT Group policy ‘We take care’, we will solve these problems, too”.

Sustainability is anchored at CHT Group and plays an important role in Bangladesh, too. The new facility of the CHT Group in Bangladesh contributes to sustainability in more ways: The roofs of two buildings are fully covered with solar photovoltaic modules. For a proper use of natural light all the other buildings have periphery glass and transparent roofs There are additionally a ground water tank to harvest rainwater as well as a biological effluent treatment plant to reuse treated water as process water in the plant.

Kelheim Fibres, a leading manufacturer of viscose speciality fibres, has joined Recycling Atelier Augsburg. Recycling Atelier Augsburg is a unique centre for research and development in the field of textile recycling. It is located at the Institut für Textiltechnik Augsburg an affiliated institute of Augsburg University of Applied Sciences. The two institutions founded the Recycling Atelier in June 2022 together with twelve partners from the German textile industry.

In the Recycling Atelier, the focus is on the triad of technical and ecological sense as well as economic benefit. In this way, the partners of the Recycling Atelier are standing up against fast fashion, outsourced corporate responsibility and a general decline in raw material quality, which often fuels downcycling - the low-quality reuse - of materials.

As a model factory, the Recycling Atelier Augsburg combines the most important processes of textile recycling and offers holistic and comprehensive research along the value chain," explains Georg Stegschuster, head of the Recycling Atelier Augsburg. The scientists research on all process steps of textile recycling: from material analysis to sorting, preparation and textile processing to sustainable product design. Comprehensive data collection and the use of artificial intelligence as well as innovative materials play a central role.

Kelheim Fibres is a producer of high-quality viscose fibres, which consist of cellulose, the main component of the renewable raw material wood, and are used worldwide for products in areas such as hygiene, textiles, and technical applications.

"In New Business Development as well as Fibre and Application Development, we follow the Open Innovation concept - the cooperation with the Recycling Atelier offers us an ideal platform for this. Here we work with partners to advance sustainability and performance," explains Maik Thiel, project manager at Kelheim Fibres.

Recycled cotton fibres are often very short or of uneven length, which makes further processing of 100 % recycled material a challenge. Adding speciality fibres from Kelheim Fibres should enable the production of high-quality new products, such as nonwovens. In the future, the fibres provided by Kelheim Fibres will also be made from recycled pulp.
