• Demo plant sorts post-consumer plastic waste and will produce ready-for-market fully formulated polymer pellets
• Brand owners and converters will be able to access material for qualification and market validation in early 2021
• EverMinds™ in action: Pioneering collaboration brings together expertise vital to advancing the circular economy

Borealis and TOMRA have today announced the operational start of their advanced mechanical recycling demo plant in Lahnstein, Germany, the result of a partnership that marries chemistry with technology for unsurpassed results.

The state-of-the-art plant processes both rigid and flexible plastic waste from households. And unlike many current recycling plants, it will produce the advanced solutions necessary for use in high-demanding plastic applications in various industries, including automotive and consumer products. With high purity, low odour, high product consistency and light colour fractions, these Borcycle™ M grade recycled polymers will meet customer quality requirements across the value chain.

The purpose of this demo plant is to generate material for brand owners and converters to qualify, validate and prove fit for use in their highly demanding applications. Technical success will set the groundwork for a commercial-scale advanced recycling plant.

“This plant is just the beginning of what’s possible when key players in the value chain come together to make a truly significant impact in the market,” says Volker Rehrmann, Executive Vice President and Head of Circular Economy at TOMRA. “Having just launched the new Circular Economy Division, it is clear what a large role waste management and pivotal projects like this have on moving towards a sustainable future. We are proud to have initiated one of the most advanced mechanical recycling plants when it comes to post-consumer polymer waste. This will become an important enabler as we accelerate the transformation to a circular economy in the years to come, and we are excited to be a part of this pioneering project.”

Operation of the plant is a joint enterprise between Borealis, TOMRA and Zimmerman. Borealis is responsible for the plant’s commercial success and contributes its expertise and knowledge in innovation, recycling and compounding. Likewise, TOMRA contributes as a provider of technology-led solutions and brings its proven expertise, established process and market knowledge, which, in turn, enable the circular economy through advanced collection and sorting systems. Zimmerman is a waste management company with experience in sorting multiple types of waste, including plastics, and is responsible for successful plant operations and product quality.

“At P&G we are making packaging with the ‘next life’ in mind to help drive a more robust circular economy.  We must increase the supply of high quality recycled plastic to enable the industry to deliver on this vision,” says Gian De Belder, Procter & Gamble (P&G) Technical Director, R&D Packaging Sustainability. “The innovative new approach that Borealis is taking shows potential to step-change both the quantity and quality of PCR available for our brands, and help us to achieve our 2030 goal to reduce our use of virgin plastic in packaging by 50%, or 300 kilotonnes annually. Early tests of the material looks very promising!”

Royal DSM, ein globales wissenschaftlich fundiertes Unternehmen für Ernährung, Gesundheit und nachhaltiges Leben, und Clariter, ein internationales Clean-Tech-Unternehmen, geben heute ihre strategische Partnerschaft bekannt. Gemeinsam wollen sie eine chemische Recyclinglösung der nächsten Generation für Produkte auf Basis von Dyneema® von DSM entwickeln, einer ultrahohen Molekülmasse (Ultra-High-Molecular-Weight Polyethylene, UHMWPE). Als erster Schritt dieser Partnerschaft wurde eine Reihe von Musterprodukten - darunter Seile, Netze und ballistische Materialien, die mit Dyneema® hergestellt wurden - in der Clariter-Pilotanlage in Polen erfolgreich umgewandelt. Dies demonstriert das Recycling-Potenzial von Dyneema® und unterstreicht das aktive Engagement von DSM Protective Materials zur Gestaltung einer nachhaltigeren Welt.

Im Einklang mit seinen ehrgeizigen Nachhaltigkeitszielen und nach der erfolgreichen Einführung von biobasiertem Dyneema® (Massenausgleich) arbeitet DSM Protective Materials aktiv an Wiederverwendungs- und Recyclinglösungen für Dyneema®-basierte Produkte am Ende ihrer Lebensdauer. Um technische Recyclinglösungen voranzutreiben, sind DSM Protective Materials und Clariter eine Partnerschaft eingegangen. Gemeinsam soll die Machbarkeit der Verwendung von Dyneema® als Ausgangsmaterial im chemischen Recyclingprozess von Clariter getestet werden. Mit Dyneema® hergestellte Musterprodukte wurden in der Pilotanlage von Clariter in Polen unter Probe gestellt. Die positiven Ergebnisse bestätigen die technische Realisierbarkeit der Umwandlung von Dyneema®-basierten Endprodukten in hochwertige Produktfamilien in Industriequalität: Öle, Wachse und Lösungsmittel durch Clariters patentierten dreistufigen chemischen Recycling-Prozess. Diese können als Inhaltsstoffe zur Herstellung neuer End- und Verbraucherprodukte weiterverwendet werden.

In Zukunft werden DSM Protective Materials und Clariter diese Initiative weiter vorantreiben, um eine nachhaltigere Welt zu gestalten. Aufbauend auf dem Erfolg des Versuchs im Labormassstab hat Clariter für 2021 Versuche im kommerziellen Massstab in seiner Anlage in Südafrika geplant. Dies mit dem Ziel, aus Dyneema® gewonnenes Rohmaterial in den europäischen Grossanlagen zu verwenden, die in den kommenden Jahren gebaut werden sollen. Darüber hinaus wird DSM weiterhin aktiv die Möglichkeiten zur Reduzierung der Umweltauswirkungen von Dyneema® über alle Produktlebensphasen hinweg untersuchen.

• "Dibella up" records its first big success

Aalten, "Dibella up" is bearing its first fruits. Since the launch of the recycling concept initiated in August 2020, six tons of sorted laundry items have already been returned to Dibella and converted into new ones by the company in farsighted reuse projects. The customer who has been involved in the project from the very beginning is Lamme Textielbeheer from Nederhorst den Berg. The Dutch textile service provider sees the initiative as an important measure for more appreciation of resources.

Dibella has taken the closed-loop approach of the textile service as a model and has taken a step towards a completely closed cycle with the "Dibella up" project. The system includes unlimited reuse and recycling of the fibre raw materials bound in the textiles. To this end, the company's own textile qualities, which are selected from laundries, are taken back and passed on to selected upcycling projects. Polyester-cotton blended fabrics are processed there into high-quality bags. Pure natural fibre textiles as well as blended fabrics with at least 50 percent cotton are chemically converted into an important raw material for cellulose fibre production, while the remaining polyester is still being thermally recycled for technical reasons.

Six tons of laundry from the Netherlands

Lamme Textielbeheer was immediately enthusiastic about the "Dibella up" initiative. The committed company has been involved in various Dibella sustainability projects for many years and recognises the future-oriented character of the new project. "Our will to cooperate was immediately clear after Dibella's managing director Ralf Hellmann presented the upcycling project, because we see it as an important measure for the prudent use of resources," reports Jan Lamme, managing director of the company of the same name. "Within a very short period of time, we therefore jointly started to take back our discarded, no longer usable old textiles. In this way, we have already been able to return six tonnes of laundry for a new product cycle. This corresponds exactly to our idea of upcycling!". "Dibella provides stable, reusable cartons for shipping," says a delighted Frank David, Lamme's Assistant Operations Manager. "This makes collection much easier for us and we don't have to take any means of transport out of our laundry".

Prepared for the mega-trend of recycling management

Dibella would like to build on the initial joint success and further expand the initiative for a closed textile cycle in the industry. "The awareness of sustainability is high in the textile rental service. But the next mega-trend is already emerging. The future lies in closed-loop recycling. With "Dibella up", we are offering our customers the opportunity to get involved now and make resources usable in the long term. We are happy about every new cooperation partner who appreciates the value of textiles as much as we do".

• Lichterlebnisse leicht wie Papier
• Wohlfühlatmosphäre mit Leuchten aus Papiergarn - ökologisch und nachhaltig

Papier ist ein nachwachsender Rohstoff, ist nahezu überall verfügbar und kann recycelt werden. Die Deutschen Institute für Textil- und Faserforschung Denkendorf (DITF) haben diesen natürlichen Werkstoff in Form von Papiergarnen verarbeitet und daraus formschöne Leuchten entwickelt. Das Ergebnis des Forschungsprojekts „Papierlicht“ sind nachhaltige Produkte mit ansprechendem Design, die kostengünstig hergestellt werden können. Die Leuchten sind voll recycelfähig.

Der Klimaschutz und die Umweltbelastung durch Mikroplastik erfordern neue Ideen, wie nachwachsende Ressourcen sinnvoll genutzt werden können. Die Forscher an den DITF haben Papiergarn mit Hilfe der Strukturspultechnologie zu sehr leichten Strukturkörpern verarbeitet. Der Herstellungsprozess ist so flexibel, dass viele verschiedene Formen möglich sind und das Licht je nach Anwendungsgebiet unterschiedlich gelenkt werden kann. Die entsprechenden lichttechnischen Kennwerte wurden an den DITF ermittelt.

Aus den Papiergarnen werden mit einer neuartigen Methode dreidimensionale Körper gefertigt. Die Garne werden mit einem Klebstoff fixiert, der ebenfalls aus nachwachsenden und abbaubaren Rohstoffen besteht. Auf die sonst übliche tragende Grundstruktur aus Metall kann verzichtet werden. Das hat mehrere Vorteile für die Umwelt: Durch den Wegfall von Draht entsteht bei der Herstellung weniger Kohlenstoffdioxid. Bei der von den DITF entwickelten Leuchte THIRTY-ONE werden dadurch mehr als zwei Kilogramm CO2-Äquivalente eingespart – pro Stück!
Ohne Metallstruktur wiegen die Papierlampen auch deutlich weniger und können leichter transportiert werden. Nach der Nutzung können die Leuchten in das Kreislaufsystem eingebracht werden.

Das Forschungsteam hat drei Demonstratorleuchten aufgebaut die zeigen, was für Möglichkeiten unterschiedliche Garnstärken, Farben und die verschieden gespulten Strukturen eröffnen. Darüber hinaus zeigen die ermittelten mechanischen Kennwerte heute schon ein großes Potential für die Nutzung in anderen Anwendungsfeldern wie beispielsweise Konstruktionsbauteile. Hierfür stehen an den DITF viele Funktionsmuster zur Verfügung.

• Kohlenstoff mit mehreren Leben

Geht es um die Zukunft der motorisierten Mobilität, reden alle vom Antrieb: Wie viel E-Auto, wie viel Verbrenner verträgt die Umwelt und braucht der Mensch? Zugleich stellen neue Antriebe erhöhte Anforderungen nicht nur an den Motor, sondern auch an dessen Gehäuse und die Karosse: Für solch anspruchsvolle Anwendungen kommen häufig Carbonfasern zum Einsatz. Wie der Antrieb der Zukunft, sollten auch die Werkstoffe am Fahrzeug umweltfreundlich sein. Deshalb ist Recycling von Carbonfasern gefragt. Lösungen dafür haben Institute der Zuse-Gemeinschaft entwickelt.

Carbonfasern, auch als Kohlenstofffasern oder verkürzt als Kohlefasern bekannt, bestehen fast vollständig aus reinem Kohlenstoff. Sehr energieaufwändig wird er bei 1.300 Grad Celsius aus dem Kunststoff Polyacrylnitril gewonnen. Die Vorteile der Carbonfasern: Sie haben kaum Eigengewicht, sind enorm bruchfest und stabil. Solche Eigenschaften benötigt man z.B. am Batteriekasten von E-Mobilen oder in Strukturbauteilen der Karosserie. So arbeitet das Sächsische Textilforschungsinstitut e.V. (STFI) aktuell gemeinsam mit Industriepartnern daran, statisch-mechanische Stärken der Carbonfasern mit Eigenschaften zur Schwingungsdämpfung zu verknüpfen, um die Gehäuse von E-Motoren im Auto zu verbessern. Angedacht ist in dem vom Bundeswirtschaftsministerium geförderten Projekt die Entwicklung sogenannter Hybridvliesstoffe, die neben der Carbonfaser als Verstärkung weitere Faserstoffe enthalten. „Wir wollen, die Vorteile unterschiedlicher Faserstoffe verbinden und so ein optimal auf die Anforderungen abgestimmtes Produkt entwickeln“, erläutert Marcel Hofmann, STFI-Abteilungsleiter Textiler Leichtbau.

Damit würden die Chemnitzer Forschenden bisherige Vliesstoff-Lösungen ergänzen. Sie blicken auf eine 15-jährige Geschichte in der Arbeit mit recycelten Carbonfasern zurück. Der globale Jahresbedarf der hochwertigen Fasern hat sich im vergangenen Jahrzehnt fast vervierfacht, laut Angaben der Industrievereinigung AVK auf zuletzt rd. 142.000 t. „Die steigende Nachfrage hat das Recycling immer stärker in den Fokus gerückt“, betont Hofmann. Carbonfaserabfälle sind ihm zufolge für etwa ein Zehntel bis ein Fünftel des Preises von Primärfasern erhältlich, müssen aber noch aufbereitet werden. Dreh- und Angelpunkt für den Forschungserfolg der recycelten Fasern sind konkurrenzfähige Anwendungen. Die hat das STFI nicht nur am Auto, sondern auch im Sport-Freizeitsektor sowie in der Medizintechnik gefunden, so in Komponenten für Computertomographen. "Während Metalle oder Glasfasern als potenzielle Konkurrenzprodukte Schatten werfen, stört Carbon die Bilddarstellung nicht und kann seine Vorteile voll ausspielen“, erläutert Hofmann.

Papier-Knowhow nutzen
Können recycelte Carbonfasern nochmals den Produktkreislauf durchlaufen, verbessert das ihre CO2-Bilanz deutlich. Zugleich gilt: Je kürzer die Carbonfasern, desto unattraktiver sind sie für die weitere Verwertung. Vor diesem Hintergrund entwickelten das Forschungsinstitut Cetex und die Papiertechnische Stiftung (PTS), beide Mitglieder der Zuse-Gemeinschaft, im Rahmen eines Forschungsvorhabens ein neues Verfahren, das bislang wenig geeignet erscheinende Recycling-Carbonfasern ein zweites Produktleben gibt. „Während klassische Textilverfahren die ohnehin sehr spröden Recycling-Carbonfasern in Faserlängen von mind. 80 mm trocken verarbeiten, beschäftigten wir uns mit einem Verfahren aus der Papierindustrie, welches die Materialien nass verarbeitet. Am Ende des Prozesses erhielten wir, stark vereinfacht gesprochen, eine flächige Matte aus recycelten Carbonfasern und Kunststofffasern“, erläutert Cetex-Projektingenieur Johannes Tietze das Verfahren, mit dem auch 40 mm kurze Carbonfasern zu attraktiven Zwischenprodukten recycelt werden können. Das danach in einem Heißpressprozess entstandene Erzeugnis dient als Grundmaterial für hochbelastbare Strukturbauteile. Zusätzlich wurden die mechanischen Eigenschaften der Halbzeuge durch die Kombination mit endlosfaserverstärkten Tapes verbessert. Das Recyclingprodukt soll, so die Erwartung der Forschenden, glasfaserverstärkten Kunststoffen, Konkurrenz machen, z.B. bei Anwendungen im Schienen- und Fahrzeugbau. Die Ergebnisse fließen nun in weiterführende Forschung und Entwicklung im Kooperationsnetzwerk Ressourcetex ein, einem geförderten Verbund von 18 Partnern aus Industrie und Wissenschaft.

Erfolgreiche Umsetzung in der Autoindustrie
Industriereife Lösungen für die Verwertung von Carbonfaser-Produktionsabfällen werden im Thüringischen Institut für Textil- und Kunststoff-Forschung Rudolstadt (TITK) entwickelt. Mehrere dieser Entwicklungen wurden mit Partnern beim Unternehmen SGL Composites in Wackersdorf industriell umgesetzt. Die Aufbereitung der so genannten trockenen Abfälle, hauptsächlich aus Verschnittresten, erfolgt nach einem eigenen Verfahren. „Dabei führen wir die geöffneten Fasern verschiedenen Prozessen zur Vliesherstellung zu“, sagt die zuständige Abteilungsleiterin im TITK, Dr. Renate Lützkendorf. Neben den Entwicklungen für den Einsatz z.B. im BMW i3 in Dach oder Hintersitzschale wurden im TITK spezielle Vliesstoffe und Verfahren für die Herstellung von Sheet Molding Compounds (SMC) etabliert, das sind duroplastische Werkstoffe, die aus Reaktionsharzen und Verstärkungsfasern bestehen und zum Pressen von Faser-Kunststoff-Verbunden verwendet werden. Eingang fand dies z.B. in einem Bauteil für die C-Säule des 7er BMW. „In seinen Projekten setzt das TITK vor allem auf die Entwicklung leistungsfähigerer Prozesse und kombinierter Verfahren, um den Carbonfaser-Recyclingmaterialien auch von den Kosten her bessere Chancen in Leichtbauanwendungen einzuräumen“, betont Lützkendorf. So liege der Fokus gegenwärtig auf dem Einsatz von CF-Recyclingfasern in thermoplastischen Prozessen zur Platten- und Profilextrusion. „Ziel ist es, die Kombination von Kurz- und Endlosfaserverstärkung in einem einzigen, leistungsfähigen Prozess-Schritt zu realisieren.“

Mountains of waste, plastic-infested oceans, negative CO2 footprints – the need for more sustainable ways of living has never been more urgent. Consequently, it is logical that recycling solutions are becoming increasingly important within the textile industry. This was also tapped into at the first virtual Global Fiber Congress in Dornbirn with a session that focused specifically on the topic. In front of around 400 participants, Markus Reichwein, Head of Product Management at Oerlikon Barmag, also spoke about solutions currently on the market.

As one of only manufactureres, the Oerlikon Group’s Manmade Fibers segment offers the entire mechanical recycling chain –from preparing the recycled materials, producing the melt all the way through to the textured package. Here, the company utilizes the VacuFil solution supplied by its subsidiary Barmag Brückner Engineering (BBE) –which, in addition to mastering bottle-to-bottle and bottle-to-textile processes, is also able to process textile waste into chips. This permits the running of textile production operations very much in line with the zero-waste philosophy.

VacuFil ensures a stable process in the case of recycled quality yarns
The reliable removal of contaminants is vital for a stable and efficient spinning process and outstanding yarn quality. At the same time, stable operating conditions with minimal fluctuations are essential. The greatest challenge here is the differing qualities of the bottle flakes fed into the system, as the extrusion process is barely able to balance these fluctuations. Here, the VacuFil concept counters with blending silos, which reduce the differences in the viscosity of the polymers considerably and guarantee high yarn and fabric quality.

The VacuFil concept is installed upstream to an Oerlikon Barmag POY system, which transforms the recycled melt into filament yarn of the accustomed high quality. As texturing solutions, Oerlikon Barmag offers its state-of-the-art automatic eAFK-series systems, including the latest generation of the eAFK Evo, which was unveiled at the ITMA Barcelona last year. Yarn manufacturers wishing to continue texturing manually can use the eFK series.

With the VarioFil R+, producers of smaller batches now also have a compact system with an integrated recycled materials preparation unit at their disposal. The system offers a special extrusion system for bottle flake materials, the very latest metering and mixing technology for spin-dying and expanded 2-stage melt filtration. The four spinning positions are each equipped with an Oerlikon Barmag 10-end WINGS POY winder.

While mechanical recycling has already been extensively developed, chemical recycling for mixed fabrics is still presenting the textile industry with huge challenges. The Oerlikon Group’s Manmade Fibers segment is currently working on solutions and concepts for transforming these fabrics into new textiles.

FINEXTM, Sateri’s marquee brand for recycled fibre, is now certified to the Recycled Claim Standard (RCS) which provides verification of recycled raw materials through the supply chain.

RCS is intended for use with any product that contains at least 5% recycled material. Sateri has successfully produced FINEXTM viscose fibres with up to 20% recycled content. Under the RCS certification process, each stage of production is required to be certified, beginning at the recycling stage and ending at the last seller in the final business-to-business transaction.

These new developments were announced at the official launch of FINEXTM on September 23, 2020. About 160 guests, mostly senior representatives of major fashion brands and fabric and garment makers, gathered to celebrate the milestones that cement the status of FINEXTM as a game changer for sustainable fashion.

Themed ‘Sustainable Fashion for the Future’, the launch was jointly hosted by Sateri and China International Fashion Fair (CHIC) on the sidelines of the three-day Intertextile Shanghai Apparel Fabrics, a major industry expo.

In his address, Allen Zhang, President of Sateri, said, “The development of FINEXTM has been an intensive effort for Sateri from initial commercialisation, to partnering brands like Lafuma and Rico Lee, and finally to today’s launch. This is all made possible with collaboration across the value chain – working alongside yarn spinners, garment makers and brand partners – to bring a high quality and more planetfriendly product to consumers. The fashion industry is changing fast and, beyond functionality, circularity is now of the greatest importance in apparel manufacturing.”

In the ‘2020 Sustainable Fashion Report’ released by China’s leading business news publication CBNweekly earlier this week, results of a survey with stakeholders in the fashion value chain reinforced the potential of textile recycling as a solution to the problem of textile waste arising from over-consumption and production. The report identified technology and capital as the biggest barriers to textile recycling and highlighted the critical role brands play in mobilising manufacturers and consumers to advance sustainable fashion.

As part of its efforts to promote textile fibre recycling in China, Sateri is in dialogue with the China Association of Circular Economy (CACE) to undertake a comprehensive study on the industrial-scale textile waste recycling landscape in the country. The study is expected to commence next year.

Rester Oy, which is developing the plant in Paimio, recycles companies' end-of-life textiles, and Lounais-Suomen Jätehuolto Oy (LSJH), which will hire a production area at the same facility, processes households' end-of-life textiles. The plant will process 12,000 tonnes of end-of-life textiles every year, which represents about 10% of Finland’s textile waste.

The textile industry’s end-of-life textile problem is intolerable. Natural resources are increasingly used to manufacture products, but these materials are lost at the end of their life cycle. About 100 million kilograms of textile waste are generated annually in Finland alone. Reusing this material could reduce the textile industry’s carbon footprint and significantly reduce the use of natural resources.

Rester Oy and LSJH will drive the textile sector towards a circular economy and begin processing textile waste as an industrial raw material. The Nordic countries’ first industrial end-of-textile refinement plant will open in Paimio in 2021. The 3,000-square-metre plant is being developed by Rester Oy, which recycles companies' end-of-life textiles and industrial waste materials. LSJH, which processes households’ end-of-life textiles on its production line, will hire part of the plant.

Outi Luukko, Rester Oy’s board chair, says, “The processing plant will begin a new era of textile circular economy in Finland. As industry pioneers, we are launching a system change in Scandinavia. The transition of the textile industry from a linear model to a circular economy is essential, as virgin materials cannot sustain the current structure of the textile industry. And why should it, when there is so much recyclable material available?”

From the perspective of Rester Oy’s main owner, work clothing supplier Touchpoint, the circular economy plant not only represents resource efficiency, but is also necessary from the perspective of the entire life cycle of a responsible work clothing collection.

Luukko adds, “Finding a local solution to a global problem is a huge leap in the right direction and raises Finland's profile as a pioneer of circular economy."

The future plant will be able to process 12,000 tonnes of end-of-life textiles annually, which represents about 10% of Finland’s textile waste. Both production lines produce recycled fibre, which can be used for various industrial applications, including yarn and fabric, insulating materials for construction and shipping industries, acoustic panels, composites, non-woven and filter materials, and other technical textiles, such as geo-textiles.

LSJH is piloting a full-scale refinement plant

LSJH has launched a pilot production line for processing households' end-of-life textiles. Unfortunately, consumers' end-of-life textiles are heterogeneous, making them a challenging raw material for further processing. Before processing, the textiles are sorted by material into various fibre classes using optical identification technology developed by LSJH and its partners. This ensures the quality of the raw material and the resulting fibre products.

Jukka Heikkilä, managing director for Lounais-Suomen Jätehuolto, explains: “On the basis of the experiences gathered from the pilot project, Lounais-Suomen Jätehuolto is preparing a full-scale refinement plant in the Turku region. As soon as 2023, the plant will process Finnish households' end-of-life textiles. The project involves all waste treatment plants owned by Finnish municipalities.”

Paimio has ambitious goals for circular economy companies

Rester’s initiative aims to create a circular economy cluster in Paimio that combines the processing and reuse of end-of-life textile fibres. Paimion Kehitys Oy, which is owned by the City of Paimio and the local association of enterprises, supports the development of circular economy companies in Paimio.

Mika Ingi, managing director for Paimion Kehitys Oy, says, “We want to step out of our traditional municipal role and create significant added value for everyone taking part. That is why we are involved in the development of a new modern service model based on ecosystem thinking. We are piloting the textile cluster, followed in the coming years by clusters focusing on plastic, construction, and energy. The aim of our service is to support and help develop new profitable business by bringing circular economy companies and their potential customers to innovate together."

The foundation stone of the processing plant was laid today (18 August 2020). The processing plant will begin operations in February 2021.

Following the successful commissioning of two new Monforts Montex wide-width stenter lines and additional environmental management equipment at its plant in Germany, GtA – Society for Textile Equipment GmbH – is aiming to be the first textile finishing company to become entirely CO2-neutral in the manufacture of all of its products by 2025.

GtA is a partner company to Germany’s large-format digital printing fabric leader, Georg and Otto Friedrich GmbH, which has has this year been able to considerably expand its portfolio due to the new Monforts lines.

Headquartered in Gross-Zimmern, close to Frankfurt, Georg and Otto Friedrich GmbH and its partners in Germany have an annual production of 37 million square metres of warp knits for a range of end-use applications, including garments, automotive interiors and technical textiles, but increasingly with a concentration on digital printing substrates.

Fault-free textiles

A new standard in pure white, 100% clean and fault-free textile substrates has been demanded by this market in recent years due to the rapid growth in digitally-printed banners and billboards – often referred to as ‘soft signage’.

The substrates of choice for digital printing are 100% polyester warp knits which are resilient and allow excellent take-up of inks, and vibrant colours and clear and precise images to be achieved with digital printing techniques. The knitted construction also has the advantage of elasticity, which is a plus in terms of flexibility for installers.

Critically, the warp knitted fabrics have extremely smooth surfaces which is becoming increasingly important due to the general move away from PVC coatings which were the standard in the past.

It was to finish these fabrics for Georg and Otto Friedrich GmbH as well as providing such services for many other customers, that the GtA plant in Neresheim, Baden-Württemberg, was established in 2015.

The purpose-built plant on a greenfield site was initially equipped with a fully-automated, 72 metre long Monforts installation comprising a washing machine integrated with a 3.6 metre wide, seven-chamber Montex stenter. The line quickly went from single to double shift production and then to 24/7 operation  to meet demand.

Expanded widths

Building on the success of this installation, GtA has now installed two more Montex stenter lines – both in expanded working widths of 5.6 metres and purpose-built at Montex GmbH in Austria.

A six-chamber Montex unit is combined with a washing machine to guarantee the purity of the substrates, while a five-chamber line is integrated with a wide-width coating machine. This new coating capability at GtA has led to a number of new additions to the Georg and Otto Friedrich DecoTex range for digital printing, including wide width fabrics with flame retardant, antimicrobial and non-slip finishes.

The new Montex stenter lines benefit from all of the latest innovations from Monforts, including the Smart Sensor system for the optimised maintenance planning of key mechanical wear components on the stenters. A comprehensive overview of the condition of all parts at any time is now available for operators within the highly intuitive Qualitex visualization software.

With Qualitex, all article-specific settings can be stored and the formulations for thousands of treatment processes called up again at any time. Individual operators can also personalise their dashboards with the most important machine functions and process parameters.

Environmental commitment

GtA is run by a seasoned team of textile professionals led by Managing Director Andreas Niess.

“We have received excellent service from Monforts from the outset and we were happy to place the order for these two new lines as part of our ongoing cooperation,” he says. “With all of the latest Monforts advances in technology we are fully in control of all production and quality parameters with these lines, as part of our significant commitment to innovative environmental technology.”

The GtA plant, which operates in near-cleanroom conditions, has also been equipped with proprietary technology to fully exploit the Monforts air-to-air heat recovery systems that are now standard with Montex stenters.

“Around 30 per cent of our investment volume at the site goes to energy-saving measures and we are sure that this commitment is worthwhile,” Mr Niess says. “As an example, our integrated heat recovery system fully exploits the waste heat from the process exhaust air and the burner exhaust gases of the Monforts stenters, allowing us to achieve an exhaust air temperature of  between 30 to 34°C, compared to what would conventionally be between 140 to 160°C. Another focus has been on exhaust air purification technology and here too, the latest technology has been installed with integrated heat recovery elements.”

This, he adds, saves 52% of the energy that would normally be used – equating to 5,800,000 KwH per year. The necessary audits for energy-efficient companies are also carried out annually.

In addition, GtA has purpose-designed the automatic chemical mixing and dosing systems that feed the padders for the key treatments that are carried out on the fabrics through the stenters.

The company is going further, however, in its pursuit of clean production and raw materials.

"We want to be an asset and not a burden on our immediate environment and therefore do not use any additives containing solvents," Mr Niess says. “We were the first to use fully halogen-free flame retardant chemistry, and we use bio-based, finely ground alumina products for the washing process instead of surfactants. PES polyester yarns made from recycled material are also increasingly used and the latest additions to our raw materials portfolio, the RC-Ocean products, are made from recycled sea plastic.

“We are now planning a combined heat and power plant for the production of electrical energy and heat and we will also build a photovoltaic system that converts solar radiation into electrical energy. GtA wants to be the first textile finishing company to be CO2-neutral in the manufacture of all of its products by 2025. The complete heat supply and heating for the 13,000 square metre production hall, as well as the office building and the hot water supply for the domestic water, is already energy-neutral. We are convinced that this commitment will pay off in the long term and our positive business development proves that sustainability and business profitability are perfectly compatible.”

In addition to the products for Georg and Otto Friedrich GmbH, GtA  offers its manufacturing capacities for other customers as a contract service.

All products are manufactured in accordance with Öko-Tex Standard 100, product class 1 and the company is also involved in the research and development of new sustainable manufacturing processes, in cooperation with many regional universities and funding project partners.
