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.

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.

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.

Abschlussmeeting im SmartERZ-Projekt TRICYCLE

Im Februar fand im Sächsischen Textilforschungsinstitut e. V. (STFI) in Chemnitz das Abschlussmeeting des Verbundprojekts „TRICYCLE – Entwicklung und Konzeptionierung eines SmartERZ Smart Composites Recycling Centers“ statt. TRICYCLE ist ein Projekt des disziplinübergreifenden Innovationsvorhaben SmartERZ aus dem Erzgebirge, welches durch das Bundesministerium für Bildung und Forschung (BMBF) im Programm „WIR! – Wandel durch Innovation in der Region“ gefördert wird. SmartERZ ist ein branchenübergreifendes Technologiebündnis zur Entwicklung von funktionsintegrierten Faserverbundwerkstoffen.

Im Februar fand im Sächsischen Textilforschungsinstitut e. V. (STFI) in Chemnitz das Abschlussmeeting des Verbundprojekts „TRICYCLE – Entwicklung und Konzeptionierung eines SmartERZ Smart Composites Recycling Centers“ statt. TRICYCLE ist ein Projekt des disziplinübergreifenden Innovationsvorhaben SmartERZ aus dem Erzgebirge, welches durch das Bundesministerium für Bildung und Forschung (BMBF) im Programm „WIR! – Wandel durch Innovation in der Region“ gefördert wird. SmartERZ ist ein branchenübergreifendes Technologiebündnis zur Entwicklung von funktionsintegrierten Faserverbundwerkstoffen.

Im Vorhaben wurde ein technologisches Recyclingkonzept für die zukünftig entstehenden smarten Produkte sowie die in der Produktion entstehenden Abfälle in der Region entwickelt. Ziel war die Entwicklung standardisierter, skalierbarer Verfahren, mit größtmöglichem Automatisierungsgrad unter Einhaltung der geltenden Gesetze, Verordnungen und Normen. Das Projekt lief vom 01.09.2021 bis 31.12.2023. Im Abschlussmeeting einer 28-monatigen Projektarbeit wurden den Teilnehmenden die Ergebnisse vorgestellt. Die Arbeit beinhaltet das Centerkonzept sowie eine Datenerhebung zu potenziell regional verfügbaren Mengen und anschließenden Verwertungsoptionen sowie die Entwicklung gewisser Designrichtlinien für das Recycling.

Eingegossen in die bestehenden Strukturen der SmartERZ Region und darüber hinaus, ist das Konzept für ein Center entstanden, welches als eine Art Drehkreuz für regionale Abfälle rund um diese Thematik fungieren soll. Darüber können Abfallströme gesammelt, erstbehandelt und für das rohstoffliche Recycling vorbereitet werden. Die Erstbehandlung schließt Technologien der Qualitätskontrolle/Qualitätsmanagement, Zerkleinerung, Pelletierung und Kompaktierung ein. Über dieses Drehkreuz sollen auch Kleinstmengen wirtschaftlich attraktiven Verwertungswegen und einer Weiterverwendung zugänglich gemacht werden.

Neben der stofflichen Vernetzung beinhaltet das Konzept für das Recycling Center die Voraussetzungen um als Vernetzungsstelle rund um die Thematik (textiler) Kreislaufwirtschaft zu fungieren. Unternehmen, Forschung, Lehre und öffentliche Einrichtungen können und sollen in Diskurs treten, um die bestmöglichen Verwertungsoptionen für entsprechende Abfälle zu finden, aber auch die Vermeidung und Wiederverwendung von Abfällen voranzutreiben, langlebige Produkte zu schaffen und Wissen zu teilen.

Die Projektpartner stimmen überein, dass nun nach Wegen gesucht werden muss, um das entstandene Konzept umzusetzen. Zusätzlich bahnen sich bereits Kooperationen mit anderen Forschungsvorhaben an. Johannes Leis als Projektleiter TRICYCLE und Dr. Stefan Minar seitens des Projekts WIRreFa sehen nun die Chance, gar die Notwendigkeit, die offensichtlichen Schnittstellen beider Projekte so schnell wie möglich zusammenzubringen. Vielleicht noch während der zweiten Phase des Projektes WIReFa.

KnitCycle: Forschungsprojekt für kreislaufgerechte Flachstrick-Textilien

87 Prozent des weltweiten Textilabfalls in der Bekleidungsindustrie landen auf Deponien oder werden verbrannt. Von den 13 Prozent, die noch mechanisch weiterverarbeitet werden, enden die meisten Alttextilien als Dämmmaterial (Downcycling). Nicht einmal ein Prozent werden zu hochwertigen Fasern aufbereitet, aus denen wieder neue Kleidung entsteht.
 
Gemeinsam mit Bache Innovative als Antragstellerin hat die Hochschule Niederrhein (HSNR) ein großes Forschungsprojekt gestartet: „KnitCycle – kreislaufgerechte Produktentwicklung für Flachstricktextilien“. Die Deutsche Bundesstiftung Umwelt (DBU) fördert das Vorhaben für zwei Jahre mit insgesamt rund 290.000 Euro, davon fließen 225.000 Euro an die HSNR.
 
Wo Textilabfall recycelt und damit in den Kreislauf zurückgeführt werden kann, muss auch weniger entsorgt werden. Werden Produktionsabfälle und -überhänge vernichtet, ist das nicht nur teuer für die Unternehmen. Für die Herstellung neuer Kleidung müssen auch wieder neue Fasern erzeugt werden. Je nach Faserstoff kommt es dabei zu großem Wasserverbrauch, starkem Pestizid- und Düngemitteleinsatz sowie langen Transportwegen mit hohen CO2-Emissionen.

Je nach Faserstoff kommt es dabei zu großem Wasserverbrauch, starkem Pestizid- und Düngemitteleinsatz sowie langen Transportwegen mit hohen CO2-Emissionen.  
 
Die Projektpartner erarbeiten ein Konzept, mit dem gestrickte Produkte so entwickelt werden können, dass sie sich am Produktlebensende durch ein Faser-zu-Faser-Recycling zu hochwertigen Fasern neu aufbereiten lassen. Aus diesen Fasern kann anschließend neues, industriell verarbeitbares Garn für Bekleidung hergestellt werden, das im Idealfall später abermals recycelt werden kann.
 
Unter dem Motto „Design for Recycling“ analysieren die Partner, welche Faktoren und Verfahren am besten geeignet sind, Textilien schon bei ihrer Entstehung so zu planen, dass sie am Produktlebensende optimal recyclingfähig sind. Gleichzeitig dürfen sich Ästhetik, Qualität und Langlebigkeit der Produkte nicht verschlechtern. Die Frage ist also: Welche Parameter im mechanischen Recycling werden benötigt und welche Produkteigenschaften erzielen das beste kreislauffähige Ergebnis?
 
„KnitCycle“ konzentriert sich auf Pulloverwaren und Produkte, die auf Flachstrickmaschinen endformgerecht in Deutschland produziert werden. Dafür liefert und produziert die auf 3D-Strickwaren spezialisierte Firma Bache Innovative eigenes Abfall- und Forschungsmaterial.
 
Unterstützung mit Experten-Knowhow gibt es auch von TURNS Faserkreisläufe. Dieses Unternehmen stellt recycelte Garne aus verschiedenen gebrauchten, ausrangierten Alttextilien her.
 
Die Faser-zu-Faser-Recycling-Versuche finden am hochschuleigenen Forschungsinstitut für Textil und Bekleidung (FTB) statt. Dazu schafft die HSNR von dem Fördergeld eine Reißmaschine für das Textilrecycling an. Hiermit werden vor Ort die optimalen Prozessparameter für das Recycling der jeweiligen Produkttypen ermittelt. Die in diesem Prozess gewonnenen Reißfasern werden dann u.a. mit Unterstützung der Firma Textechno H. Stein GmbH & Co. KG aus Mönchengladbach analysiert und bewertet.

Mittels unterschiedlicher Aufbereitungs- und Spinnverfahren werden aus den Reißfasern anschließend neue Garne hergestellt. Die Forschenden testen, wie sich die Fasern wiederverspinnen lassen – auch in Kombination mit anderen Naturfasern, um mit möglichst hochwertigen neuen Produkten den Produktkreislauf zu schließen.

An Labor-Strickmaschinen erzeugt das FTB-Team erste 2D-Strickproben. Die finalen Strickprodukte aus den recycelten Garnen stellt der Kooperationspartner Bache Innovative her.

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. The binder-free material based on bio-fibers is also industrially compostable.
In addition, the experts will be giving trade fair visitors an insight into Freudenberg’s filtration portfolio.

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.

Textile waste: Eastman and Patagonia join forces

Eastman announces a partnership with Patagonia to address textile waste.

The outdoor apparel company teamed up with Eastman to recycle 8,000 pounds of pre- and post-consumer clothing waste, which Eastman processed through its molecular recycling technology. The process involves breaking down Patagonia’s unusable apparel into molecular building blocks that Eastman can use to make new fibers.

"We know apparel waste is a major problem, and consumers increasingly want better, more sustainable solutions when their most loved clothing reaches the end of its life," said Natalie Banakis, materials innovation engineer for Patagonia.

"Our collaborations show the world what’s possible when it comes to sustainability,” said Carolina Sister Cohn, global marketing lead for Eastman textiles. “We have the technology to make the textiles industry circular, and we know it requires collaboration with innovative brands to make circular fashion possible. This is only the beginning, and we look forward to more collaborations throughout 2024."

VliesComp
The aim of the industrial partners Tenowo GmbH (Hof), Siemens AG (Erlangen), Invent GmbH (Braunschweig) and STFI united in the VliesComp project is to bring recycled materials back onto the market in various lightweight construction solutions. The application fields "Innovative e-machine concepts for the energy transition" and "Innovative e-machine concepts for e-mobility" were considered as examples. On display at JEC World in Paris will be a lightweight end shield for electric motors made from hybrid nonwovens - a mixture of thermoplastic fibre components and recycled reinforcing fibres - as well as nonwovens with 100% recycled reinforcing fibres. The end shield was ultimately manufactured with a 100% recycled fibre content. The tests showed that, compared to the variant made from primary carbon fibres using the RTM process, a 14% reduction in CO2 equivalent is possible with the same performance. The calculation for the use of the prepreg process using a bio-resin system shows a potential for reducing the CO2 equivalent by almost 70 %.

Bast fibre reinforcement
To increase stability in the plant stem, bast fibres form in the bark area, which support the stem but, in contrast to the rigid wood, are very flexible and allow slender, tall plants to move in the wind without breaking.A new process extracts the bast bark from hemp by peeling.The resulting characteristic values, such as tensile modulus of elasticity, breaking strength and elongation, are very promising in comparison with the continuous rovings made of flax available on the market.The material could be used as reinforcement in lightweight construction.At JEC World, STFI will be exhibiting reinforcing bars that have been processed into a knitted fabric using a pultrusion process based on bio-based reinforcing fibres made from hemp bast for mineral matrices.

Recycled fibres: Swiss manufacturers for circularity

Many end-users now expect recycled materials to be in textile products they purchase – and this is driving innovation throughout the industry. However, there are still many technical and economic issues facing yarn and fabric producers using recycled resources. Members of the Swiss Textile Machinery Association offer some effective solutions to these challenges.

Synthetic recycled materials such as PET can usually be treated similarly to new yarn, but there are additional complexities where natural fibres like wool and cotton are involved. Today, there’s a trend towards mechanically recycled wool and cotton fibres.

Many end-users now expect recycled materials to be in textile products they purchase – and this is driving innovation throughout the industry. However, there are still many technical and economic issues facing yarn and fabric producers using recycled resources. Members of the Swiss Textile Machinery Association offer some effective solutions to these challenges.

Synthetic recycled materials such as PET can usually be treated similarly to new yarn, but there are additional complexities where natural fibres like wool and cotton are involved. Today, there’s a trend towards mechanically recycled wool and cotton fibres.

Spinning recycled cotton
The use of mechanically recycled fibres in spinning brings specific quality considerations: they have higher levels of short fibres and neps – and may often be colored, particularly if post-consumer material is used. It’s also true that recycled yarns have limitations in terms of fineness. The Uster Statistics 2023 edition features an extended range of fibre data, supporting sustainability goals, including benchmarks for blends of virgin and recycled cotton.
In general, short fibres such as those in recycled material can easily be handled by rotor spinning machines. For ring spinning, the shorter the fibres, the more difficult it is to guide them through the drafting zone to integrate them into the yarn body. Still, for wider yarn counts and higher yarn quality, the focus is now shifting to ring spinning. The presence of short fibres is a challenge, but Rieter offers solutions to address this issue.

Knitting recycled wool
For recycling, wool fibres undergo mechanical procedures such as shredding, cutting, and re-spinning, influencing the quality and characteristics of the resulting yarn. These operations remove the natural scales and variations in fibre length of the wool, causing a decrease in the overall strength and durability of the recycled yarn. This makes the yarn more prone to breakage, especially under the tension exerted during knitting.

Adapting to process recycled materials often requires adjustments to existing machinery. Knitting machines must be equipped with positive yarn suppliers to control fibre tension. Steiger engages in continuous testing of new yarns on the market, to check their suitability for processing on knitting machines. For satisfactory quality, the challenges intensify, with natural yarns requiring careful consideration and adaptation in the knitting processes.

From fibres to nonwovens
Nonwovens technology was born partly from the idea of recycling to reduce manufacturing costs and to process textile waste and previously unusable materials into fabric structures. Nonwovens production lines, where fibre webs are bonded mechanically, thermally or chemically, can easily process almost all mechanically and chemically recycled fibres.

Autefa Solutions offers nonwovens lines from a single source, enabling products such as liners, wipes, wadding and insulation to be produced in a true closed loop. Fibres are often used up to four times for one product.

Recycling: total strategy
Great services, technology and machines from members of Swiss Textile Machinery support the efforts of the circular economy to process recycled fibres. The machines incorporate the know-how of several decades, with the innovative power and quality standards in production and materials.
Stäubli’s global ESG (environmental, social & governance) strategy defines KPIs in the context of energy consumption, machine longevity and the recycling capacity in production units worldwide, as well in terms of machinery recyclability. The machine recyclability of automatic drawing in machines, weaving systems and jacquard machines ranges from 96 to 99%.

Klarheit im Begriffs-Dschungel der Circular Economy

Wie unterscheiden sich Wiederverwendung und Recycling? Wie ist der deutsche Begriff Mehrweg zu verwenden, wie grenzt er sich von Einweg ab? Für welche Bewertung sind Wiedereinsatzquoten sinnvoller als Recyclingquoten? Antworten auf diese nicht zuletzt durch die PPWR (Packaging & Packaging Waste Regulation der EU) aufgeworfenen Fragen und kurze Erläuterungen zu Begrifflichkeiten der Kreislaufführung von Verpackungen liefert das neue auf Deutsch und Englisch erschienene »Mehrweg-Glossar/Glossary on Reuse«. Das Fraunhofer-Institut für Umwelt-, Sicherheits- und Energietechnik UMSICHT und das Fraunhofer-Institut für Materialfluss und Logistik IML erstellten dies im Auftrag der Stiftung Initiative Mehrweg, um Klarheit in die oft nicht trennscharfen Begrifflichkeiten rund um Wiederverwendung und die Circular Economy zu bringen.

Das rund 40 Seiten umfassende, zweisprachige Glossar hat das Ziel, Beschreibungen und Vergleiche im Bereich der wiederverwendbaren und rezyklierbaren Verpackungssysteme zu schärfen. Das Werk soll als Arbeitshilfe dienen, um die Kommunikation zwischen Wissenschaft, Politik, Unternehmen und Verbraucher*innen zu erleichtern. Begrifflichkeiten wie Recycling, Reutilization, Einweg, Mehrweg oder Recyclingquoten sind omnipräsent, jedoch nicht immer trennscharf definiert. Beispielsweise werden Wiederverwendung und Recycling manchmal als konkurrierende Verfahren angesehen, manchmal fungiert Recycling als Oberbegriff, manchmal Wiederverwendung. »In diesem Glossar betrachten wir die Wiederverwendung als zerstörungsfreie Kreislaufführung, d.h. das Objekt und seine Form bleiben erhalten, während das Recycling einen zerstörenden Aufbereitungsprozess beschreibt, bei dem es vor allem um den Stofferhalt geht«, gibt Jürgen Bertling von Fraunhofer UMSICHT und Mitautor des Glossars einen Einblick.

Das Glossar ist in vier Kapitel unterteilt: Zunächst erläutert das Autorenteam relevante Aspekte für den Vergleich von Verpackungssystemen, das nächste Kapitel enthält Übersichtsgrafiken zu Verpackungstypen in Abhängigkeit ihrer Kreislauffähigkeit und eine schematische Darstellung verbundener Kreisläufe. Die Definitionen aller relevanten Begrifflichkeiten wie z. B. Wiederverwendung und Weiterverwendung sowie eine Abgrenzung und Einordnung der im Deutschen verwendeten Begrifflichkeiten Einweg und Mehrweg finden sich im dritten Kapitel. Das Glossar schließt mit einem Kapitel zu Formeln und Formelzeichen für Berechnungen, die zu einer möglichst allgemeinverständlichen Schreibweise in wissenschaftlich-technischen Analysen beitragen sollen.

SiWerTEX erforscht simultane Rückgewinnung von Faserpolymeren und Wertstoffen

Textil-Recycling ist eine der großen Herausforderungen unserer Zeit. Aktuell wird der Großteil der gebrauchten Kleidung (über 85 %) thermisch verwertet oder landet auf Deponien. Ein deutlich kleinerer Anteil wird als Second-Hand Kleidung in Entwicklungsländer verschifft. Lediglich weniger als ein Prozent der Kleidung wird recycelt und anschließend wieder zu Kleidung verarbeitet.

Textilien zu recyceln ist kompliziert. Für Sammlung und Sortierung der Altkleider gibt es noch keine etablierten Systeme. Mechanische Verfahren zur Rückgewinnung von Fasern resultieren häufig in einer schlechteren Qualität der textilen Produkte und chemische Verfahren sind technisch kaum entwickelt, sowie wirtschaftlich noch nicht attraktiv genug. Dies gilt auch für das weltweit am häufigste produzierte synthetische Textilfasermaterial Polyester, das aus dem gleichen Material wie PET Flaschen hergestellt wird. Das derzeit in der Textil- und Bekleidungsindustrie genutzte recycelte PET (rPET) stammt fast ausschließlich aus recycelten PET-Flaschen.

Forscher:innen des Forschungsinstituts für Textil- und Bekleidung (FTB) der Hochschule Niederrhein und des Instituts für Chemische und Thermische Verfahrenstechnik (ICTV) der Technischen Universität Braunschweig nehmen sich im Projekt SiWerTEX den Hürden der simultanen Rückgewinnung von Monomeren und werthaltigen Zuschlagsstoffen aus dem Recycling von Polyestertextilien an. Das Bundesministerium für Wirtschaft und Klimaschutz finanziert im Rahmen der Industriellen Gemeinschaftsforschung (IGF) die Entwicklungsarbeit der Wissenschaftler:innen unter der Leitung von Professorin Dr.-Ing. Maike Rabe (FTB) und Professor. Dr.-Ing. Stephan Scholl (ICTV).

Zusammen mit deutschen Textilherstellern und Textilausrüstern wollen die Wissenschaftler:innen ein chemisches Verfahren zum PET- bzw. Polyesterrecycling, weiterentwickeln. Eine große Herausforderung stellt dabei die Vielfalt von Ausrüstungsmitteln und Additiven dar, mit denen Kleidung und technische Textilien ausgestattet sind: sie sind gefärbt, bedruckt und mit Flammschutz- oder Weichgriffmitteln ausgerüstet.

Untersucht wird im Projekt nicht nur, wie dies beim Recycling effektiv entfernt werden kann, sondern auch, ob die Additive als Wertstoffe zurückgewonnen werden können. Der Fokus wird in SiWerTEX auf die Entfernung von Farbstoffen und die Rückgewinnung des in Flammschutzmitteln enthaltenen Phosphors gerichtet. Die Erkenntnisse sollen helfen, Textilien von Beginn an so zu produzieren, dass ein späteres Recycling möglich wird.

Für die Textil-Unternehmen werden zum Ende des Projektes Handlungsempfehlungen für recyclingfreundliche Färb- und Ausrüstungsprodukte herausgegeben werden können.

Refashion: Renewal of accreditation for 2023-2028

Refashion, a textile industry’s eco-organisation, has renewed its authority approval until 2028. 6 years during which it will continue to transform the industry in keeping with the objectives set by the French Ministry of Ecological Transition and the French Ministry of the Economy, including the objective to collect 60% of CHF (clothing, household linen and footwear textiles) placed on the market by 2028. This new period is reflected in an ambitious road map and significantly increased investment. Nearly 1.2 billion euros, financed by the marketers, will be spent on transforming the industry during this new period of authority approval.

This new period is reflected in an ambitious road map and significantly increased investment. Nearly 1.2 billion euros, financed by the marketers, will be spent on transforming the industry during this new period of authority approval.

Determined to achieve the objectives set out in the ambitious specifications set down by the Secretary of State at the Ministry of Ecological Transition, Berangère Couillard, Refashion has worked on a road map with all of its stakeholders involved in the transformation that is underway. Maud Hardy, nominated as the eco-organisation’s CEO in January 2022, started a collaborative working method that will continue throughout this new period to support areas that are key in this transformation. In the next few months, projects will begin and will visibly highlight the progress made in the three phases of a product’s life cycle: production consumption, regeneration.

Production

  • Recognising eco-design initiatives through the eco-modulation of the fees paid by marketers (durability, environmental information labelling, integration of recycled materials). For marketers, these initiatives should represent the scheme’s cornerstone. The aim is to involve all stakeholders in reducing the environmental impact of products.

Consumption

  • As from 2023, Refashion will spend 5 million euros minimum per year in awareness-raising activities and on information to the general public by supporting an array of local authority initiatives.
  • The launch of a repair fund in 2023, in particular to prolong the usage of textiles and footwear products. More than 150 million euros will be invested between 2023 and 2028 to change the habits of the French population to increase repairs by 35% (guideline target by the ADEME 2019).

Regeneration

  • Accelerating clothing, household linen and footwear collection, in particular thanks to an operational mix in the sector. Funding traditional sorting operators will remain central, but Refashion will also develop an additional operational system in order to achieve the collection target of 60% of products placed onto the market (versus 34% in 2021).
  • 5% of fees paid to Refashion will go towards the redeployment/reuse funds to provide support for reuse within the remit of stakeholders in the Social and Solidarity Economy. In addition to this funding, additional funding arrangements open to all stakeholders will be established. The total budget throughout the authority approval period represents 135 million euros.
  • 5% of fees, i.e., 58 million euros in 6 years, will be spent on R&D to help achieve these milestones in order to industrialise the recycling of used CHF: recyclability that is considered during the design stage; automated sorting and recycling.
