From the Sector

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.

Stahl, an active proponent of responsible chemistry, has been awarded the highest EcoVadis Platinum rating, placing it within the top 1% of companies assessed by EcoVadis. The award underlines Stahl’s commitment to collaborating with its partners to reduce its environmental impact and build a more responsible and transparent supply chain.

EcoVadis is a globally recognized evidence-based assessment platform that reviews the performance of more than 90,000 organizations across key sustainability criteria. These include environmental impact, labor and human rights standards, ethics, and sustainable procurement practices. The latest report from EcoVadis highlights Stahl’s positive progress across all these areas and builds on the Gold rating achieved by the company in 2021. Stahl’s 2030 target is to maintain the EcoVadis Platinum rating by working closely with its value-chain partners to help them reduce their environmental impact – including by supporting their transition to renewable feedstocks. In 2021, 80% of Stahl’s total spend on raw materials was supplied by EcoVadis-rated suppliers.
 
The new EcoVadis rating comes as Stahl accelerates its efforts to ensure a more responsible and transparent supply chain. Recent steps toward this goal have included establishing a dedicated Supply Chain Transparency division within the company’s Environmental, social, and governance (ESG) department. The division will be tasked with coordinating a new product development framework that prioritizes the responsible sourcing of raw materials. Furthermore, in July 2022, Stahl submitted a new greenhouse gas (GHG) emissions reduction target, including a specific commitment regarding the company’s Scope 3 upstream emissions. Stahl aims to reduce these by at least 25% over the next 10 years, compared with the base year (2021). Stahl expects to achieve this reduction primarily by working with its suppliers to replace fossil-based raw materials with lower-carbon alternatives.

• Values from the past 30 years more relevant than ever and are reflected in recent growth

During its 30^th anniversary, the international OEKO-TEX^® Association is still seeing positive business development despite numerous global challenges. In total, OEKO-TEX^® issued more than 36,000 certificates and labels in the past financial year – an increase of 14% compared to the previous year. The STeP by OEKO-TEX^® facility certification recorded the strongest growth, almost doubling compared to 2020/2021. The number of labels and certificates issued increased from 31,696 to 36,084 between July 1st, 2021, and June 30th, 2022.

"Since OEKO-TEX^® was founded in 1992, our business practices have been aligned with our core values," says OEKO-TEX^® Secretary General Georg Dieners. “Sustainability, trust and safety build upon each other and are the basis of transparent and sustainable action. We underpin responsible action with our independent scientific methods and are valued in the industry as an effective, solution-oriented partner.” In the past financial year, this was reflected in the new Impact Calculator, with which STeP by OEKO-TEX^®-certified companies calculate their CO₂ emissions and measure their water consumption to ultimately reduce both. For OEKO-TEX^®, a sustainable future is inextricably linked to a transparent status quo. "By setting the highest standards and communicating them openly, we encourage companies and consumers to do the same," says Dieners.

To maintain trust and credibility, OEKO-TEX^® includes external perspectives. The International Advisory Board reviews proposals of the OEKO-TEX^® Working Groups and provides important impetus for continuous optimization of the standards. Additionally, a Public Stakeholder Consultation was conducted in March 2022 to gain comprehensive insights from all interest groups. These are now being integrated into the further development of the standards and services. The investments of the past financial year reflect how important quality assurance and product control are for the OEKO-TEX^® Association: Almost 40% of the total expenditure flowed into these two items.

In the meantime, the basic business continues to progress successfully. The number of STANDARD 100 by OEKO-TEX® certificates issued in the 2021/2022 financial year exceeded 25,000 for the first time. More than 15,000 chemicals, colorants and auxiliaries were certified with ECO PASSPORT by OEKO-TEX^®.

In autumn 2022, OEKO-TEX^® will launch a certification to help companies comply with upcoming due diligence laws. With RESPONSIBLE BUSINESS by OEKO-TEX^®, OEKO-TEX^® is responding to the increasing global expectations of compliance with due diligence requirements in companies. The new standard is based on the EU proposal for due diligence, the German Due Diligence Act, which will come into force from 2023, and numerous other international legislative proposals.

• Monomaterial solution contains renewably-sourced polypropylene from the Bornewables™ portfolio of circular polyolefins
• Trexel employs its proprietary MuCell® technology to deliver a range of lightweighting benefits
• EverMinds™ in action: reuse and design for recycling are focus of value chain collaboration

Borealis and Trexel, an expert in foaming injection and blow moulded parts, announce that they have co-developed a new plastic bottle based on a grade from the Bornewables™ portfolio of polyolefins made using renewable feedstocks derived 100% from waste and residue streams. The lightweight bottle – which will be showcased at the Borealis stand at the K 2022 (from 19 to 26 October 2022 in Düsseldorf) – is reusable and fully recyclable. It boasts a significantly lower overall CO₂ footprint because it is composed of renewably-sourced feedstock and produced in the foaming process.

The Bornewables™ portfolio of circular polyolefins helps reduce the carbon footprint while offering material performance equal to virgin polymers. Using Bornewables grades allows for design freedom and colour flexibility, and helps retain a premium look and feel. The grades – which are commercially available in Europe – help conserve natural resources because they are derived solely from waste and residue streams, for example from used cooking oil. Reusing waste already in circulation instead of fossil fuel-based feedstocks enhances the sustainability of applications made using the Bornewables grades.

The reusable new bottle developed by Borealis and Trexel retains its value over many life cycles thanks to the use of Trexel’s proprietary technology in tandem with Bornewables grades; as a material solution, the new bottle minimises the use of valuable raw materials. Moreover, converters consume less energy in the production process when using the MuCell® technology. The bottle thus helps close the loop on plastics circularity by way of design for recycling, the use of renewable feedstocks, and excellent material performance across multiple life cycles.

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.

The future of e-mobility will be determined in particular by safe battery enclosures. As batteries for electric vehicles become more performant, higher volumetric energy density plays a crucial role. If more energy is to be stored in less installation space, new material and design solutions are required. The development of suitable enclosures made of safe and highly robust lightweight materials is also required. This is a case for the Aachen Centre for Integrative Lightweight Production (AZL). A project on cell-to-pack battery enclosures for battery-electric vehicles, which has been eagerly awaited in the industry, will start in October this year there.

The design of battery housings is crucial for safety, capacity, performance, and economics. The Cell-to-Pack project, which is starting now, will focus on developing concepts for structural components and for producing them based on a variety of materials and design approaches. The concepts will be compared in terms of performance, weight and production costs, creating new know-how for OEMs, producers and their suppliers throughout the battery vehicle value chain. Companies are now invited to participate in this new cross-industry project to develop battery enclosure concepts for the promising and trend-setting cell-to-pack technology.

The basis for the project is the lightweight engineering expertise of the AZL experts, which they have already demonstrated in previous projects for multi-material solutions for module-based battery housings. Together with 46 industry partners, including Audi, Asahi Kasei, Covestro, DSM, EconCore, Faurecia, Hutchinson, Johns Manville, Magna, Marelli and Teijin, 20 different multi-material concepts were optimized in terms of weight and cost and compared with a reference component made from aluminum. All production steps were modelled in detail to obtain reliable cost estimates for each variant. Result: depending on the concept, 20% weight or 36% cost savings potential could be identified by using multi-material composites compared to the established aluminum reference.

It is expected that the design concept of battery enclosures will develop in the direction of a more efficient layout. In this case, the cells are no longer combined in modules in additional production steps, but are integrated directly into the battery housing. The elimination of battery modules and the improved, weight-saving use of space will allow for higher packing density, reduced overall height and cost saving. In addition, various levels of structural integration of the battery housing into the body structure are expected. These new designs bring specific challenges, including ensuring protection of the battery cells from external damage and fire protection. In addition, different recyclability and repair requirements may significantly impact future designs. How the different material and structural options for future generations of battery enclosures for the cell-to-pack technology might look like and how they compare in terms of cost and environmental impact will be investigated in the new AZL project. In addition to the material and production concepts from the concept study for module-based battery enclosures, results from a currently ongoing benchmarking of different materials for the impact protection plate and a new method for determining mechanical properties during a fire test will also be incorporated.

The project will start on October 27, 2022 with a kick-off meeting of the consortium, interested companies can still apply for participation until then.

• 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.
