From the Sector

RecyOuest, France, has successfully started up the world's first recycling line for agricultural plastic waste nets at its mill in Argentan. The innovative recycling line featuring a unique dry-cleaning system was delivered, installed and commissioned by the international technology group ANDRITZ in August 2022.

RecyOuest, based in Argentan, France, is a green economy company that handles the recycling contaminated filamentary thermoplastics such as round bale nets and twines. With its recycling process, RecyOuest is part of a circular economy approach.

The ANDRITZ recycling line can process up to 8,000 tons of waste and produce recycling fibers for nonwoven applications and also for pellets made of waste from agricultural single-use plastic nets and twines. These pellets are then returned to the plastics industry by mixing both recycled and virgin raw materials, thus reducing the amount of virgin plastic used.

This line, inspired by the techniques from textile wastes recycling, is equipped with a unique mechanical dry-cleaning system that allows resource savings by avoiding the use of water and chemicals. This state-of-the-art ANDRITZ equipment allows RecyOuest to produce recycling fibers for nonwoven applications and also pellets for ever new eco-designed nets and twines for the agricultural sector, with the lowest possible environmental impact.

Automotive carpets are typically multi-layered systems that can be challenging to recycle. By introducing a carpet made of 100% polyester, Autoneum now opens up new opportunities for vehicle manufacturers to meet their sustainability targets. The innovative carpet systems are fully recyclable, thus paving the way for an improved and more sustainable end-of-life recycling of electric vehicles. In addition, the high content of recycled PET as well as the zero waste and less energy-intensive production process further improve the carbon footprint of Autoneum’s new monomaterial needlepunch and tufted carpets.

Autoneum’s fully recyclable carpet systems ensure a closed material loop and are thus proof of the Company’s commitment to improving the sustainability performance of its products and manufacturing processes. The 100% polyester carpets build on the existing lightweight and particularly sustainable Autoneum Pure technologies: the carpet surface, for example, is made of Di-Light or Relive-1, while Hybrid-Acoustics PET is used for the decoupler. Thanks to Autoneum’s innovative alternative backcoating (ABC) process, which uses a thermoplastic adhesive instead of latex, the production of the new monomaterial needlepunch and tufted carpets also requires significantly less energy and no water at all.

Autoneum’s sustainable tufted carpet system made of 100% polyester is already in development for an electric model of a German vehicle manufacturer that will be available in Europe and Asia.

After two years of joint collaboration and research the Swiss Textile Recycling Project “Texcircle” comes to an end. Partners and stakeholders have worked on the vision of a textile cluster where materials flow in circular loops. The goal of the project was to develop high-quality yarns and products incorporating such a large amount of recycled textiles as possible. In the end, several product prototypes from carpets, socks, and curtains to pullovers, padding and accessories have been developed with at least 50 % recycled fiber up to 80 % recycled fibers and yarns.

Europe has a waste problem of 7.5 million waste of which only 30-35 % is collected and less than 1 % of the textile and clothing worldwide is recycled into textiles and clothing again. It is as well found that around 80 % of the impact of a textile product lies in the design.

Together with the design research expertise of the Lucerne University of Applied sciences and arts, the spinning expertise of Rieter and the sorting and collection expertise of Texaid, systems should be created where products of high quality can be produced of recycled fiber. On board were the expertise of further Cluster partners of Brands, Retailers, and the public sector to see how a joint Cluster and system coukld be established.

The Project Texcircle and cluster is led by the Lucerne University of Applied Sciences and Arts – Art  & Design, and in collaboration with Coop, Rieter, Jacob Rohner AG, Ruckstuhl AG, TEXAID as well as workfashion.com ag. Furthermore, Bundesamt für Zivildienst ZIVI, NIKIN AG, and Tiger Liz Textiles are supporting the project. The project is funded by Innosuisse.

Furthermore, collaboration partners from all over Europe contributed to the project to enable these prototypes and systems.

Through joint developments from the design, the collecting, sorting trials, tearing, and spinning trials until the actual production trials and product testing. The partners were able to recycle 2.5 Tons of pre-and post-consumer textile waste into product prototypes with a promising commercial interest. From socks, west, and pullovers to non-woven felts and accessories to carpets and curtains. Through our 2 years of collaboration, the teamcame across several hurdles in the textile recycling value chain which could be tackled. This was a proof of concept that a circular system is possible and the industry now has to enable this at full scale.

• Lenzing becomes partner company of CISUTAC
• New project CISUTAC, co-funded by the EU, shall remove barriers to circularity in the textile industry
• Lenzing will make a contribution in cellulose recycling

The Lenzing Group, a leading provider of specialty fibers for the textile and nonwoven industries, is reinforcing its commitment to circularity by becoming a partner in the CISUTAC (Circular and Sustainable Textile and Clothing) project that is co-funded by the EU. The new consortium was established to support the transition to a circular and sustainable textile sector and, as well as Lenzing, the 27 consortium members include the industry association Euratex, textile company Inditex, PVH, Decathlon and non-governmental organization Oxfam. For its part, Lenzing is focusing on the development of recycling processes for cellulose.
 
CISUTAC aims to remove current bottlenecks in order to enhance textile circularity in Europe. Its goal is to minimize the sector’s total environmental impact by developing sustainable, novel and inclusive large-scale European value chains.

Ganesha Ecopet Private Limited, a subsidiary of Indian PET recycling pioneer Ganesha Ecosphere Ltd., has recently opened its new Warangal facility under the brand name Go Rewise where it produces rPET for filament yarns and fibres, as well as for food-grade packaging.  

The company has installed two Starlinger PET recycling lines in its facility in Warangal, Telangana state. Ganesha Ecopet plans to supply the produced rPET granulates under its newly introduced brand enterprise Go Rewise. Launched under the umbrella of one of India's rPET industry leaders, Go Rewise is committed to supplying highest quality rPET products that are produced in a resource-efficient process.
One Starlinger recycling line, a recoSTAR PET 165 H-VAC, processes washed PET bottle flakes for the Go Rewise polyester filament yarn applications and reaches an output of approx. 14,000 tons per year. With the second Starlinger recycling line, Ganesha is producing food-grade rPET resins.

Ganesha Ecosphere looks back on 30 years of experience in the PET recycling business and can be considered a role model regarding sustainable business activities. Founded in 1987, the company started out as a yarn processing facility. It was among the first companies in India to start reprocessing PET waste to manufacture recycled polyester staple fibre (RPSF) and recycled polyester spun yarns (RPSY) in 1994. By today, the group has established a large network of over 300 scrap vendors located across the country and operates four factories in India - two in Uttar Pradesh, one in Uttarakhand, and the recently opened one in Telangana. It also recently operationalised its first factory outside India in Nepal. With over 500 customers and exports to more than 18 countries, the company ranks among the largest rpet producers in India with 130,000 tonnes per year and currently recycles around 16 - 18 % of India's total PET waste.

Launched this September, the new Horizon Europe project CISUTAC will support the transition to a circular and sustainable textile sector. As part of a consortium of 27 partners working on the project, TEXAID will among others support the project with sorting, disassembly and repair trials.

The production and consumption of textile products continue to grow, together with their impact on the environment, due to a lack of reuse, repair and recycling of materials. Quality, durability, and recyclability are often not being set as priorities in the design and manufacturing of clothing (EU Strategy for Sustainable and Circular Textiles, March 2022).  

CISUTAC aims to remove current bottlenecks in order to increase textile circularity in Europe. The objective is to minimise the sector’s total environmental impact by developing sustainable, novel, and inclusive large-scale European value chains.  

The project will cover most parts of the textile sector by working on two material groups representing almost 90% of all textile fibre materials (polyester, and cotton/cellulosic fibres), and focusing on products from three sub-sectors experiencing varying circularity bottlenecks (fashion garments, sports and outdoor goods, and workwear).  

CISUTAC will follow a holistic approach covering the technical, sectoral and socio-economic aspects, and will perform three pilots to demonstrate the feasibility and value of:

• Repair and disassembly
• Sorting (for reuse and recycling)
• Circular garments through fibre-to-fibre recycling and design for circularity

To realise these pilots, the consortium partners will:

• Develop semi-automated workstations
• Analyse the infrastructure and material flows
• Digitally enhance sorting operations (for reuse and recycling)
• Raise awareness among the consumers and the textile industry

As part of the CISUTAC consortium, TEXAID, will conduct different trials of sorting, repair, and disassembly, and be active in the LCA and Standardisation work packages.

Im Automobilbau, dem Schiffsbau und der Luftfahrtindustrie sowie bei Windenergieanlagen steigen die Materialanforderungen zusehends. Die verwendeten Werkstoffe sollen leicht, ressourcenschonend und gleichzeitig hochbelastbar sein. Faserverstärkte Kunststoffe (Composites) rücken immer mehr in den Vordergrund, da deren Eigenschaften in Kombination mit Glas- oder Carbonfasern metallischen Materialien oftmals überlegen sind. Mit Fokus auf die klimaneutrale Herstellung und Nutzung von Produkten wächst auch der Bedarf an Recyclinglösungen. Im SmartERZ-Projekt TRICYCLE arbeiten Unternehmen gemeinsam an geeigneten skalierbaren und wirtschaftlich tragfähigen Prozessen zum Recycling von Smart Composites. Momentan gibt es dafür keine Anbieter oder Konzepte am Markt.

Smart Composites bestehen aus Werkstoffen, deren Funktionalisierung durch die Integration oder Applikation elektrisch leitfähiger Komponenten, z. B. Sensoren oder Mikroprozessoren, erreicht wird. Dazu zählen zum Beispiel smarte Textilien, die elektronisch wärmen, Lichtsignale geben oder zur Datenübertragung genutzt werden können. Das breite Anwendungsspektrum und die vielseitigen Einsatzgebiete dieser intelligenten Verbundwerkstoffe und Multimaterialverbunde werden perspektivisch zu einem wachsenden Bedarf und einer stärkeren Nachfrage führen.

Die funktionale und vielschichtige Verbindung verschiedener Materialien wie Kunststoff, Metall und Textil wirft beim Thema Recycling Nachhaltigkeitsfragen auf. Im Erzgebirge werden dafür bereits heute Lösungen entwickelt. Im Rahmen des WIR!-Projektes SmartERZ ist das Verbundprojekt TRICYCLE entstanden. Mit dem Fokus auf den Strukturwandel im Erzgebirge haben sich acht ortsansässige Partner aus Wissenschaft und Wirtschaft zusammengetan, um ein Recyclingkonzept aufzustellen und die Grobplanung für ein erzgebirgisches Recycling Center zu entwickeln. Das Ende des Produktlebenszyklus und die Nachnutzung bzw. Wiederaufbereitung stehen dabei im Mittelpunkt des Entwicklungsprozesses. Im Ergebnis sollen effektive und maßgeschneiderte Maßnahmen für eine möglichst hochwertige Wiederverwendung entstehen. Diese sollen dem steigenden Aufkommen an Abfällen aus diesem wachsenden Bereich der deutschen Industrie begegnen und anwendungsbereit sein.

Klassische Herausforderungen für die Projektbeteiligten sind die irreversiblen Verbindungstechniken (z. B. Kleben, Faser-Matrix-Haftung), die Integration vieler verschiedener Materialien in geringen Mengen sowie Form und Größe der Bauteile. Eigene Untersuchungen sowie Feedback von Partnerunternehmen bestätigen die Notwendigkeit sowie den Nutzen eines passgenauen Recyclingprozesses für Smart Composites und intelligente Multimaterialverbünde. Das Projekt soll dazu beitragen, den Wirtschaftsstandort Erzgebirge attraktiver und zukunftsfähiger zu gestalten.

Am 1. September 2021 gestartet, kann TRICYCLE erste Ergebnisse vorweisen. Zunächst wurden die Bedarfe bei mittelständischen Unternehmen in der Region Erzgebirge abgefragt, um die aktuellen Gegebenheiten und den Status quo in Bezug auf technologische Recyclingkonzepte bestmöglich abzubilden. Für ein fundiertes Recyclingkonzept hat das TRICYCLE-Team drei Referenzbauteile für den vorgesehenen Prozess ermittelt, die in der erzgebirgischen Wirtschaft Verwendung finden, und folgenden Bereichen zugeordnet: Automotive, Technische Textilien mit applizierter Zusatzfunktion und Technische Textilien mit integrierter Zusatzfunktion.

Basierend auf dieser Auswahl, analysiert das Projektteam momentan die Herstellungs- und bisherigen Recyclingprozesse der Referenzbauteile. Das beinhaltet auch die Planung praktischer Versuche zum Recycling. Dabei fokussieren sich die Projektpartner auf ihr Know-how in verschiedenen chemischen, thermischen und mechanischen Prozessen zur Separierung, Rückführung und Wiederverwendung der eingesetzten Materialien. Um die Produkte den Recyclingtechnologien zugänglich zu machen, wurde die Herangehensweise innerhalb des Projekts angepasst, da insbesondere Textil aufgrund von Form und Struktur (z. B. endlose Struktur) herausfordernd sein kann.

Obwohl die Materialien selbst recycelbar sind, müssen diese dennoch für den Prozess optimal vorbereitet bzw. fachgerecht aufbereitet werden. Die Expertise und die Technologiekompetenz, die hierfür benötigt werden, ist bei den beteiligten Projektpartnern durch jahrzehntelange Erfahrung und zahlreiche Innovationen vorhanden. Das Zusammenspiel aller Beteiligten im Projekt TRICYCLE stellt bereits jetzt die Weichen für das geplante Recycling Center, um dieses später zum Drehkreuz zwischen regionalen Produktionsunternehmen und dem Recycling weiterzuentwickeln. Dieses soll als „Open Factory“ aufgebaut werden, um den Unternehmen des SmartERZ-Bündnisses bzw. perspektivisch der Region Erzgebirge eine gemeinsame Nutzung zu ermöglichen.

„Die Wiederverwendung der eingesetzten Ressourcen ist sowohl aus ökonomischer als auch aus ökologischer Sicht zwingend geboten. Momentan gibt es weder Anlagenbauer noch Dienstleistungsanbieter mit den entsprechenden Kompetenzen zum Recycling von Smart Composites oder Multimaterialverbünden am Markt,“ stellt Johannes Leis, der Verbundkoordinator vom Sächsischen Textilforschungsinstitut e.V. (STFI) in Chemnitz fest.Unter Leitung des STFI als Verbundkoordinator mit seiner über 30-jährigen Erfahrung in der Textilbranche und speziellem Know-how im Recycling von Carbonabfällen haben sich weitere Unternehmen und Forschungseinrichtungen zusammengefunden. Dazu zählen das Textilunternehmen Curt Bauer GmbH, die Professur Fabrikplanung und Fabrikbetrieb der TU Chemnitz, das Ingenieurbüro Matthias Weißflog, der Hersteller für Faserverbundbauteile Cotesa GmbH, der Spezialvlieshersteller Norafin Industries (Germany) GmbH, das Recyclingunternehmen Becker Umweltdienste GmbH und die Hörmann Rawema Engineering & Consulting GmbH. Am Ende der Projektlaufzeit sollen ein einsatzfähiges, technologisches Recyclingkonzept für die zukünftigen entstehenden smarten Produkte sowie die in der Produktion entstehenden Abfälle (bspw. durch fehlerhafte Bauteile und Randbeschnitte) und ein Konzept für den Aufbau eines Recycling Centers vorliegen, das im Erzgebirge entstehen soll.

More than 350 million tons of plastic are produced worldwide every year, and vast amounts of plastic waste simply end up in the environment. The circular economy offers enormous potential for keeping plastics in the loop and thus conserving resources and the environment. Since 2018, six Fraunhofer institutes in the Fraunhofer CCPE cluster have been researching how to make the plastics value chain circular, and Prof. Manfred Renner has been the new head of the cluster since August 2022. Research results, implementation projects and strategies to accelerate the transformation to a circular plastics economy will be presented by Fraunhofer CCPE at the first international Fraunhofer CCPE Summit on February 8 and 9, 2023 in Munich.

In a circular plastics economy, resources can be saved, products can be intelligently designed for long service life, and end-of-life losses can be reduced. Systemic, technical and social innovations are needed to make the transition from a linear to a circular economy a success. This is what the Fraunhofer Cluster of Excellence Circular Plastics Economy CCPE is researching in the three divisions “Materials”, “Systems” and “Business”. The cooperation of the six Fraunhofer institutes IAP, ICT, IML, IVV, LBF and UMSICHT enables a multi-stakeholder approach in which the appropriate R&D competencies are bundled.

Fraunhofer CCPE would like to present and discuss successful projects and research approaches on an international scale at the Fraunhofer CCPE Summit on February 8 and 9, 2023 in Munich. The summit is to become an international forum for exchanging ideas for solutions and innovations for a circular plastics economy.

Cross-industry collaboration - local, regional and international
Since August 2022, Prof. Manfred Renner, Institute Director of Fraunhofer UMSICHT, is the new head of Fraunhofer CCPE. He succeeds Prof. Eckhard Weidner, who has retired. “Cross-industry cooperation - very local, but also regional and international - is the elementary prerequisite for a functioning circular plastics economy. At the summit, players from all points of the compass will meet and network in order to rethink the plastics value chain together," explains Prof. Manfred Renner, adding, “We want to provide answers to the following questions:  How can we make all Circular Economy principles, i.e. the ten R-strategies, known? How can industry, science and society best cooperate in a transformation to a circular plastics economy for the greatest possible impact?”

Results of the Fraunhofer CCPE cluster so far are innovative approaches for circular business models, intelligent collection, sorting, and recycling technologies, but also new formulations for circular polymers and compounds to enable multiple recycling cycles. With the newly developed assessment tool CRL® , companies can, for example, self-assess the maturity of products or product systems with regard to the circular economy. The tool checks the extent to which a product already takes into account circular economy principles in the areas of product design, product service system, end-of-life management and circular economy, and where there is still potential for improvement.

Geosynthetics have become an indispensable part of the construction industry. PP nonwovens, for example - mechanically bonded continuous fibres made from specially UV-stabilised polypropylenes - are often used in blanket form as barriers, screens and filters, and their strength extends the service life of construction projects. Whether for road construction, or as barrier on glaciers or against weeds - there are myriad applications.

TenCate Geosynthetics uses the PURE LOOP ISEC evo technology to recycle this type of PP nonwoven. The European company, with locations in Austria, France and the Netherlands, is specialised in the development and production of geotextiles for modern civil engineering applications. The edge trimmings and production rejects generated during manufacturing used to be recycled at the Linz site, but not fed back into the company's own production process.

"The demands on us were high," recalls Patrick Wiesinger, project manager at PURE LOOP. "The PP nonwoven is highly tear resistant, which means its a very challenging recycling process. Our ISEC evo machine conserves the quality of the production waste really well during recycling, so we were able to achieve the specified increase in quality for the recyclates."

Another advantage of PURE LOOP technology is the wide range of shapes in which the production scrap can be delivered for processing. "Our ifeed technology with double feed ram system and singleshaft shredder offers the ideal conditions for direct processing of these large rolls - and without the need for prior preparation of the input material by employees before the material is fed into the recycling process", emphasizes Patrick Wiesinger. With the ISEC evo recycling machine TenCate can now manufacture its high-strength PP nonwoven product with a recyclate content of up to 10 percent.

• Recypur successfully starts up a complete airlay line delivered by ANDRITZ for its mill in L’Alcúdia, Spain

The airlay line is designed for recycling of post-industrial and post-consumer foam and was developed specifically for the bedding and furniture industry, with material heights reaching 20 cm and densities of up to 120 kg/m3. Experimental tests carried out together with experts from ANDRITZ Laroche led to the conclusion that the mechanical method for recycling polyurethane is the most versatile and reliable.

With a capacity of 1.2 t/h, this airlay line enables Recypur to supply new mattresses made of industrial & post-consumer foam waste from old mattresses. This well proven process allows to reduce the environmental impact, increase self-sufficiency and eventually reduce the use of polyurethane. Such a set-up also allows multiple functional materials to be incorporated into the blend, such as flame-retardant, conductive and insulating fibers, among others. Thanks to this tailored approach, Recypur is now able to expand its diversification, innovation and reputation on the Spanish market.

The scope of supply includes a blending line with five feeders, an Exel 1500 for fine opening, an Airlay Flexiloft+ with 2.20 m working width, a recycling machine and an oven.

Airlay lines strongly support the circular economy and are part of ANDRITZ’s comprehensive product portfolio of sustainable solutions that help customers achieve their own sustainability goals in terms of climate and environmental protection.

Recypur, based in the Spanish province of Valencia, is part of DELAX, a Spanish group specialized in manufacturing and commercialization of innovative beds and mattresses. This company is the first Spanish manufacturer of recycled flexible polyurethane foam cores from post-consumer foam waste.
