EREMA: Circular economy for PET fibres

The textile industry is the third largest consumer of plastics. While growth rates in the production of fibres and textiles are high, the circular economy has hardly become established in this segment. The EREMA Group is now intensifying development of recycling solutions for this application with their new fibres and textiles business unit. Currently, the focus is on PET fibre materials from fibre production and subsequent processing steps. Technologies for recycling mixed fibre textiles from textile collection sources are to follow in a follow-up project phase.

The textile industry is the third largest consumer of plastics. While growth rates in the production of fibres and textiles are high, the circular economy has hardly become established in this segment. The EREMA Group is now intensifying development of recycling solutions for this application with their new fibres and textiles business unit. Currently, the focus is on PET fibre materials from fibre production and subsequent processing steps. Technologies for recycling mixed fibre textiles from textile collection sources are to follow in a follow-up project phase.

"With EREMA's VACUREMA® and INTAREMA® technology and PURE LOOP's ISEC evo technology, our company group already has an extensive range of machines for fibre and PET recycling applications. For ecologically and economically sound recycling, however, new technological solutions are needed to use the recycled fibres in higher-value end applications and to achieve a functioning circular economy," explains Wolfgang Hermann, Business Development Manager Application Fibres & Textiles, EREMA Group GmbH. The initial focus will be on PET, regarded as a key material for the production of synthetic fibres. The aim is to find recycling solutions that allow PET fibre materials to be prepared for reuse in PET fibre production processes. This is a significant step for the circular economy because PET fibres in textiles account for about two-thirds of the total volume of PET.

In this development work, the EREMA Group can build on existing know-how. Proven recycling technologies have been combined with a new IV optimiser. "This extends the residence time of the PET melt, which is particularly necessary in fibre recycling to efficiently remove spinning oils. Our recycling process also increases the IV value of the PET melt after extrusion back to the specific level that is essential for production of the fibre," explains Hermann. Waste PET fibre from production processes can therefore be further processed into rPET filament fibre, carpet yarn and staple fibre.

Fibre test centre with plant to test customers' materials
In order to accelerate development work, EREMA opened its own fibre test centre a few months ago, where a cross-company team is working on recycling solutions for fibre-to-fibre applications.

Fraunhofer CCPE on the way to an international circular plastics economy

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.

More than 350 million tons of plastic are produced worldwide every year, and vast amounts of plastic waste simply end up in 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.

Borealis and Trexel develop fully recyclable lightweight bottle

  • 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.

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.

PURE LOOP: High-strength synthetic nonwoven made with a recycled content of 10 percent

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 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.

Coperion: New Development for Plastic Fiber and Flake Recycling

With the goal of making recycling of lightweight, high-volume fiber and flake recyclate much more economical and, in some cases even possible, Coperion has developed a new version of its ZS-B side feeder. Using the innovative ZS-B MEGAfeed, plastic recyclate with a bulk density under 200 kg/m³, long considered intake-limited and thus not worth recycling, can be reliably fed in large quantities into Coperion’s ZSK twin screw extruder and be concurrently recycled and compounded.

The ZS-B side feeder’s novel design makes it possible to feed very high rates of fiber and flakes, such as PA, PE, PET, and PP. As a result, the ZSK twin screw extruder’s high capacity can be fully exploited when the ZS-B MEGAfeed is used. Very high throughputs in both mechanical and chemical recycling of post-industrial and post-consumer waste are achieved.

The ZS-B side feeder’s novel design makes it possible to feed very high rates of fiber and flakes, such as PA, PE, PET, and PP. As a result, the ZSK twin screw extruder’s high capacity can be fully exploited when the ZS-B MEGAfeed is used. Very high throughputs in both mechanical and chemical recycling of post-industrial and post-consumer waste are achieved.

Increased Throughput in Numbers
With a ZSK 58 Mc18 twin screw extruder, the throughput increase and thus the potential of the new ZS-B MEGAfeed becomes very clear. When recycling PA fibers with a bulk density of ~40-50 kg/m3, throughputs of 70 kg/h were previously achieved using conventional equipment. When the PA fibers were fed into the ZSK extruder using the ZS-B MEGAfeed, throughputs increased about fourteenfold to 1,000 kg/h. Similar results were achieved recycling carbon fibers with a bulk density of ~50-70 kg/m3; in this case, throughputs increased from 50 kg/h to 2,500 kg/h using the ZS-B MEGAfeed. When recycling PCR (Post-Consumer Recycled) flakes, throughputs increased from 50 kg/h to 700 kg/h, and from 80 kg/h to 1,300 kg/h with multilayer film flakes.

Key to Economical Recycling of A Wide Variety of Plastics
Plastics previously considered not recyclable are becoming a valuable raw material using the new Coperion ZS-B MEGAfeed. For example, PCR flakes or recyclate from carbon fiber-reinforced plastics can now be fed into the ZSK extruder at high feed rates and recycled economically.

In the case of mechanical upcycling, upstream processes necessary for compounding, such as compacting, melting and agglomeration, are completely eliminated using the ZS-B MEGAfeed technology. In this recycling process, flakes and fibers can be fed directly into the ZSK extruder, where they are melted, compounded, devolatilized, and filtered in a single step. In so doing, both investment costs and energy consumption drop. The production process becomes significantly more efficient. Moreover, the thermal product stress is reduced and recyclate quality increases.

Even when recycling PET, the feed rate is no longer a limiting factor. With the ZS-B MEGAfeed, PET flakes and fibers can be fed into the ZSK twin screw extruder in large quantities with no pre-drying or crystallizing, where they can be processed with the highest degree of profitability.

The ZS-B MEGAfeed can also feed large quantities of post-consumer waste, adding appreciable value to the chemical recycling process with the ZSKs. ZSK throughput rates are very high with the ZS-B MEGAfeed. Preheating of the recyclate via mechanical energy input of the twin screws thus becomes even more economical for further processing in the reactor.

Existing Coperion extruders can be retrofitted with ZS-B MEGAfeed technology to greatly expand their spectrum of applications and increase their throughput rates.

EREMA: Working together with Recycling Company Anviplas

The Spanish recycling company Anviplas has been involved in plastics recycling for more than 30 years, during which time it has built up extensive know-how that now benefits customers throughout Europe, in Africa and in Asia. Their cooperation with EREMA is almost as long. Since 1991, Anviplas has relied on the technology and service provided by the Austrian recycling machine manufacturer.

The Spanish recycling company Anviplas has been involved in plastics recycling for more than 30 years, during which time it has built up extensive know-how that now benefits customers throughout Europe, in Africa and in Asia. Their cooperation with EREMA is almost as long. Since 1991, Anviplas has relied on the technology and service provided by the Austrian recycling machine manufacturer.

Employing 64 people, Anviplas recycles post-industrial and post-consumer plastic waste, especially HD and LD-PE as well as PP, to make recycled pellets in all colour variations. The production capacity is 1,800 tonnes per month. An EREMA type INTAREMA® 1716 TVEplus® recycling machine with screen changer is in operation at the site in Navarcles (Barcelona) for processing the PP material stream. This patented extruder system was developed for handling difficult-to-process materials, such as heavily printed films as well as very moist waste. This machine is characterised by its optimised 3-stage degassing system; firstly by preheating and predrying the material in the preconditioning unit, secondly because the screw design allows reverse degassing, and thirdly in the degassing zone of the extruder.

Anviplas customers manufacture a huge bandwidth of products made using their recycled pellets. They range from various film products, such as stretch, shrink, mulch and silage films, to irrigation, corrugated and high-pressure pipes, as well as containers such as tubs, bottles, barrels and crates.

In February 2022 the Repeats Group, a pan-European platform for LDPE recycling, and Anviplas announced, that Repeats has made an investment in the Spanish recycling company. For Repeats this investment in Anviplas represents an important step in building a pan-European plastics recycling platform.

EREMA: Large-scale recycling Plants for production capacity up to 40,000 tonnes per year

As the demand for recycled plastics grows, so does the size of the machines. This applies to the processing of polyolefins as well as to PET recycling. With its unique dimensions and production capacity, this new size of plant features a screw diameter of 280 mm, implemented for the first time in a VACUREMA® Basic 2628 T large-scale project for producing rPET pellets. EREMA has just shipped the plant to a customer in Brazil.

EREMA has just shipped the plant to a customer in Brazil.

Up to 40,000 tonnes per year of rPET meeting the highest quality standards can now be produced. "For this purpose, we installed a screw with a length of ten meters, a diameter of 280 millimetres and a weight of 3.5 tonnes, which is the largest ever used in one of our recycling machines," explains Managing Director Michael Heitzinger. The screw was manufactured by 3S, a subsidiary of EREMA GmbH. No less impressive is the reactor of this recycling system, which, with a height of around 10 metres, is also unique and almost reaches the roof of the new production hall. 500 tonnes of input material were recycled during the test phase, which was subject to strict quality control. "The entire project was a great team effort," Heitzinger said, thanking everyone involved.

EREMA as a partner for large-scale projects
Just four years ago, the largest extrusion line supplied by EREMA was designed for a throughput of 15,000 tonnes per year. This size of plant was ordered by customers once or twice a year. In the meantime, machines like this leave the production site in Ansfelden every month. As early as 2020, EREMA proved to be a pioneer and reliable partner for implementing unique large-scale projects. That was when the food and beverage packaging manufacturer Envases Universales Mexico commissioned two VACUREMA® Basic 2625 T machines, each with a screw diameter of 250 mm and a capacity of 30,000 tonnes per year.

Sein Engagement um den wissenschaftlichen Nachwuchs unterstreicht der Verein mit der Prämierung herausragender Bachelor- und Masterarbeiten. Die diesjährigen Auszeichnungen erfolgten im Rahmen der gestrigen Mitgliederversammlung, auf der evo-Vorstand Christian Basler als neuer Vorstandsvorsitzender des Fördervereins gewählt wurde.

Der UMSICHT-Förderverein ist ein wichtiger Partner des Oberhausener Forschungsinstituts und verfügt über ein großes Netzwerk aus Politik, Wirtschaft und Industrie. Neben der Verleihung des UMSICHT-Wissenschaftspreis ist die gezielte Nachwuchs- und Projektförderung ein zentrales Anliegen des mittlerweile über 30 Jahre bestehenden Vereins. So werden auf der jährlichen Mitgliederversammlung Menschen ausgezeichnet, die innovative Projekte bearbeiten und besondere Arbeit geleistet haben. In diesem Jahr erhielten die UMSICHT-Forschenden Laura Huwald und Tobias Rieger eine finanzielle Zuwendung von je 10 000 Euro für ihre Forschungsvorhaben. Die beiden Studentinnen Sonja Frerich und Hannah Brenner freuten sich über insgesamt 750 Euro Preisgeld für ihre herausragenden Bachelor- und Masterarbeiten.

Neuartige Brennstoffzellen
Laura Huwald, Abteilung Elektrochemische Energiespeicher, untersucht die »Entwicklung und Charakterisierung kohlenstoffbasierter poröser Transportlagen für Brennstoffzellen«. Dank der Substitution durch kohlenstoffbasierte Materialien kann das neuartige Zellkonzept mittels kostengünstiger und langzeitstabiler Komponenten realisiert werden. Ihre Arbeit bietet die Grundlage zur Initiierung eines Nachfolgeprojekts mit Industriebeteiligung, in dem ein Prototyp des neuartigen Brennstoffzellenkonzepts mit den am Fraunhofer UMSICHT entwickelten Bipolarplatten realisiert werden soll.

Innovative Recyclingverfahren für Kunststoffabfälle
Tobias Rieger überprüft im Projekt SubForceH2 das »Chemische Recycling von Kunststoffabfällen zur Substitution fossiler Rohstoffe in der chemischen Industrie und der Erzeugung von Wasserstoff«. Dadurch können z. B. CO2-Emissionen eingespart werden, da der in Kunststoffabfällen gebundene Kohlenstoff nicht durch konventionelle Müllverbrennung freigesetzt, sondern durch die Umsetzung zu chemischen Grundstoffen im Kreislauf gehalten wird. Als Nebenprodukt entsteht zudem Wasserstoff, welcher in zahlreichen industriellen Anwendung benötigt und zur Speicherung von Energie zunehmend an Bedeutung gewinnt.

Masterarbeit: Kunststoffe in Böden
Im Rahmen ihrer Masterarbeit »Entwicklung, Validierung und Anwendung einer Methode zur Untersuchung von Kunststoffemissionen auf landwirtschaftlichen Nutzflächen« entwickelte Hannah Brenner eine praxisorientierte Methode, mit der Bodenproben nach ihrer Entnahme auf dem Feld aufbereitet und hinsichtlich ihres Mikroplastikgehalts analysiert werden können. Ziel ist die Einschätzung der Belastung von Feldflächen durch Kunststoffemissionen und der anschließende Vergleich mit anderen Habitaten. Dadurch soll eine schnellstmögliche Reduzierung des Mikroplastikeintrags in terrestrische Ökosysteme erreicht werden.

Herausragende Bachelorarbeit
Hauptbestandteil von Sonja Frerichs Bachelorarbeit war es, die mechanische Eignung eines neuartigen, am Fraunhofer UMSICHT entwickelten Materials für den Einsatz in Brennstoffzellen zu untersuchen. Im Fokus stand die Umformbarkeit von thermoplastbasiertem Folien-BPP (BPP: Blasextrudiertes Polypropylen), um Gasverteilungsstrukturen für Wasserstoff und Sauerstoff einprägen zu können. Die Vermessung der eingeprägten Strukturen wurde unter anwendungsnahen Bedingungen durchgeführt.

EPTA highlights opportunities for pultruded composites in energy-efficient building

Buildings are responsible for approximately 40% of all energy consumption and 36% of CO2 emissions in the EU. Improving energy efficiency in buildings therefore has a key role to play in achieving the ambitious goal of carbon neutrality by 2050 set out in the European Green Deal. A new briefing from the European Pultrusion Technology Association (EPTA) discusses how composite materials can help improve the thermal performance of the building envelope to satisfy increasingly stringent energy efficiency regulations. The EPTA report, Opportunities for pultruded composites in energy-efficient buildings, explains how pultruded profiles offer durable,  low maintenance solutions which can help reduce both operational and embodied carbon emissions from buildings in applications including energy-saving windows, thermal break connectors, and solar shading and cladding systems.   

Buildings are responsible for approximately 40% of all energy consumption and 36% of CO2 emissions in the EU. Improving energy efficiency in buildings therefore has a key role to play in achieving the ambitious goal of carbon neutrality by 2050 set out in the European Green Deal. A new briefing from the European Pultrusion Technology Association (EPTA) discusses how composite materials can help improve the thermal performance of the building envelope to satisfy increasingly stringent energy efficiency regulations. The EPTA report, Opportunities for pultruded composites in energy-efficient buildings, explains how pultruded profiles offer durable,  low maintenance solutions which can help reduce both operational and embodied carbon emissions from buildings in applications including energy-saving windows, thermal break connectors, and solar shading and cladding systems.   

“Economic and population growth mean energy demand is set to rise, making energy efficiency measures even more critical,“ comments Dr Elmar Witten, Secretary of EPTA. “Regulations and standards will continue to push for lower U-values for building elements, driving the increase use of materials and designs which minimise operational carbon emissions. Pultruded profiles offer an attractive combination of properties for designers of energy-efficient buildings – low thermal conductivity to minimise thermal bridging, together with excellent mechanical performance, durability, and design freedom.“  
 
It is estimated that today, roughly 75% of the EU building stock is energy inefficient, meaning that a large part of the energy used goes to waste. This energy loss can be minimised by improving existing buildings and striving for smart solutions and energy efficient materials for new builds. Areas of focus include improving glazing systems, better insulation of envelope components, and reducing unwanted solar heat gains. The low thermal conductivity of composites is being exploited in components and structures that help to minimise energy required for space conditioning.

Lenzing: Clear positioning of the EU Commission against plastic waste

  • Guidelines of the EU Commission to implement the Single-Use Plastics Directive have been published
  • Uniform labelling obligation for wipes and feminine hygiene products containing plastics as of July 03, 2021
  • Lenzing’s wood-based, biodegradable VEOCEL™ branded fibers as a sustainable alternative to plastic

The Lenzing Group welcomes the issuance of the guidelines for the implementation of the Single-Use Plastics Directive (EU) 2019/904, which took effect on June 05, 20191. In these guidelines, the EU Commission specifies which products fall within the scope of the directive, thus providing clarity in the joint fight of the EU member states against environmental pollution from plastic waste. Lenzing’s wood-based, biodegradable cellulosic fibers such as those of the VEOCEL™ brand comprise a sustainable and innovative solution to this man-made problem.

Lenzing’s wood-based, biodegradable cellulosic fibers such as those of the VEOCEL™ brand comprise a sustainable and innovative solution to this man-made problem.

Uniform labelling rules for some single-use plastic products
The Commission implementing regulation (EU) 2020/2151 applying to the Single-Use Plastics Directive stipulate uniform labelling requirements for some of the single-use plastic products on the packaging or the product itself starting on July 03, 2021. They encompass feminine hygiene products and wet wipes for personal and household care containing plastic.

Consumers want sustainable hygiene products
Even before the implementation of the Single-Use Plastics Directive, Lenzing already gives consumers clear guidance in their purchasing decisions. Products bearing the VEOCEL™ brand logo on their packaging are produced in line with stringent certification criteria. As a consequence, consumers can be assured that the products contain biodegradable, cellulosic materials.

A Marketagent survey carried out in German-speaking Europe in October 20192 concluded that nine out of ten consumers would immediately change their purchasing behavior for wipes if they found out that their current product contains plastic. This would seem to imply that new market dynamics will emerge once the labelling rules for single-use plastic products takes effect. According to a Smithers Report3, about 500,000 tons of petroleum-based fibers are used each year for the production of wipes.

Fraunhofer: Kompendium zu Kunststoff in der Umwelt

Was ist Mikroplastik genau? Welche Bewertungsverfahren für Kunststoffeintrag in die Umwelt gibt es? Worin unterscheiden sich Duroplaste, Thermoplaste und Elastomere? Das neu erschienene »Kompendium Kunststoff in der Umwelt« zielt darauf ab, solch grundlegende Fragen rund um Plastik in der Umwelt zu beantworten – völlig unabhängig von bestimmten Fachdisziplinen.

Was ist Mikroplastik genau? Welche Bewertungsverfahren für Kunststoffeintrag in die Umwelt gibt es? Worin unterscheiden sich Duroplaste, Thermoplaste und Elastomere? Das neu erschienene »Kompendium Kunststoff in der Umwelt« zielt darauf ab, solch grundlegende Fragen rund um Plastik in der Umwelt zu beantworten – völlig unabhängig von bestimmten Fachdisziplinen. Das Kompendium dient als Hilfsmittel, um den gesellschaftlichen und wissenschaftlichen Diskurs zu diesem Thema auf eine gemeinsame fachliche Basis zu stellen.

Das Themenfeld Plastik in der Umwelt ist für unterschiedliche Fachdisziplinen relevant. Definitionen und Fachtermini rund um Kunststoffe werden allerdings oft fachspezifisch bzw. kontextbezogen genutzt. Entsprechend existieren für einen Begriff zuweilen unterschiedliche Bedeutungsebenen. Um eine gemeinsame Basis im Diskurs zum Thema Plastikverschmutzung und seine Auswirkungen auf Mensch und Umwelt zu schaffen, haben Wissenschaftler*innen das 54 Seiten umfassende Kompendium »Kunststoff in der Umwelt« erstellt. »Für eine inter- und transdisziplinäre Zusammenarbeit zu Kunststoff in der Umwelt ist ein gemeinsames Grundverständnis unabdingbar«, erklärt der federführende Autor Jürgen Bertling des Fraunhofer UMSICHT.

Einheitliche Definitionen auf Deutsch und Englisch
Das im März auf Deutsch erschienene »Kompendium Kunststoff in der Umwelt« adressiert die Fachöffentlichkeit, beantwortet aber auch grundlegende Fragen rund um Plastik in der Umwelt. Somit kann es auch als Hilfsmittel für Behörden, Politik, Medien, Umweltorganisationen und die interessierte Öffentlichkeit genutzt werden. Die englische Version ist derzeit noch in Bearbeitung. Es wurde auch erarbeitet, um eine einheitliche Sprachregelung innerhalb des BMBF-Forschungsschwerpunkts »Plastik in der Umwelt« sowie in der Kommunikation nach außen zu unterstützten.

In insgesamt 13 Kapiteln werden die jeweils wichtigsten Begriffe und Definitionen benannt, erläutert und kontextualisiert. Das Kompendium arbeitet dabei vor allem mit bestehenden Definitionen (u. a. DIN/CEN/ISO-Normen oder rechtliche Definitionen aus der bundesdeutschen Gesetzgebung); eine eigene Definitionsarbeit wird nur sehr begrenzt geleistet. Dabei wird im Einzelfall verdeutlicht, wie Begriffe korrekt verwendet und welche Begriffe nicht gebraucht werden sollten. Das Kompendium beinhaltet zudem ein Stichwortverzeichnis, sodass die Erläuterungen zu gesuchten Begriffen schnell ausfindig gemacht werden können.

Das Kompendium »Kunststoff in der Umwelt« wurde im Rahmen des Querschnittsthemas »Begriffe und Definitionen« des BMBF-Forschungsschwerpunkts »Plastik in der Umwelt« erarbeitet. Wissenschaftler*innen aus den Verbundprojekten ENSURE, EmiStop, Innoredux, InRePlast, MaReK, MicBin, MicroCat»ch_Balt, MikroPlaTaS, PlastikBudget, PLASTRAT, RAU, ResolVe, RUSEKU, revolPET, SubµTrack und TextileMission haben sich aktiv an der Erstellung des Kompendiums beteiligt.

AVK: Elektro-Mobilität bietet große Chancen für den Einsatz von Composites

Die anstehende Verkehrswende ist eines der zentralen wirtschaftlichen und industriellen Themen unserer Zeit. Umweltschutz und ein möglichst nachhaltiger Umgang mit unserem Planeten und seinen endlichen Ressourcen sowie der Wunsch nach individueller Mobilität dürfen sich zukünftig nicht mehr gegenseitig ausstechen. Es gilt Lösungen zu finden, die beide Wünsche gleichberechtigt berücksichtigen.

In den letzten Jahren steht bei der Betrachtung möglicher Alternativer Antriebssysteme vor allem der Wechsel von klassischen Verbrennungsmotoren hin zur Elektro-Mobilität im Fokus. Auch wenn es zahlreiche weitere Optionen gibt, so ist diese das derzeit politisch und auch wirtschaftlich oftmals präferierte Modell, auf das die Automobilindustrie mit allen vor- und nachgelagerten Industriezweigen reagieren muss.

In den letzten Jahren steht bei der Betrachtung möglicher Alternativer Antriebssysteme vor allem der Wechsel von klassischen Verbrennungsmotoren hin zur Elektro-Mobilität im Fokus. Auch wenn es zahlreiche weitere Optionen gibt, so ist diese das derzeit politisch und auch wirtschaftlich oftmals präferierte Modell, auf das die Automobilindustrie mit allen vor- und nachgelagerten Industriezweigen reagieren muss.

Auch für die Composites-Industrie ergeben sich neue Herausforderungen. Bislang ist der Transportbereich mit einem Anteil von 32 % das zweitwichtigste Anwendungssegment der Composites Industrie (vgl. Abb. 1). Betrachtet werden hier alle Lang- sowie Endlosfaserverstärkten Materialsysteme. Änderungen und neue Impulse in diesem so wichtigen Bereich haben, sowohl für die deutsche Industrie generell als auch für die Zulieferindustrie im Speziellen, einen fundamentalen Einfluss auf viele Akteure im Composites-Markt.

Bereits vielfach wurde in den letzten Monaten ein Abgesang auf die Composites im Automobilbereich angestimmt, da Leichtbau seinen Einfluss bei der E-Mobilität vermeintlich verloren habe. Dies muss sich, wenn man die reine Physik betrachtet, schon grundlegend als falsch herausstellen und wurde mittlerweile ja auch vielfach entkräftet. Darüber hinaus wird aber übersehen, dass Composites über ein enorm vielfältiges und breites Eigenschaftsniveau, auch über den Leichtbau hinaus aufweisen. Die Leichtbaumöglichkeiten sind nur ein Baustein der für den Einsatz von Composites, vor allem auch in der Elektromobilität spricht.

Wie genau Composites zukünftig eingesetzt werden können und wo sich die meisten Potenziale zeigen, dass war Thema einer Arbeitskreissitzung der AVK zum Thema "Werkstoffeigenschaften und -anforderungen für die E-Mobilität“. Mehr als 150 angemeldete Teilnehmer informierten sich am 24. März über den aktuellen Stand aus Forschung und Entwicklung sowie derzeitige und zukünftige Anwendungsszenarien.

Leitfähige Kunststoffe, Kunststoffe im Hochvoltbereich, aber auch direktgekühlte Motoren aus faserverstärkten Kunststoffen waren dabei ebenso Thema, wie neue Materialentwicklungen und konkrete Anwendungsfelder im PKW-Bereich.

Potenziale für den Einsatz von Kunststoffen und ganz speziell auch Composites zeigen sich beispielsweise im Bereich des Batteriegehäuses bzw. des Deckels der Batteriegehäuse.

Das Batteriegehäuse inklusive Deckel ist in einem Fahrzeug ein Teil der gesamten Fahrzeugstruktur. Das Gehäuse beherbergt die Zellen, die Kühlung, die Verkabelung und schützt vor Crash-/Crush- Schäden. Composites verfügen u. a. über eine gute Zug- und Biegefestigkeit und erhöhen die Steifigkeit. Darüber hinaus ist eine hohe Formstabilität und elektrische Isolation garantiert. Spontanversagen des Bauteils gibt es nicht. EV (electric vehicle)-Batterien haben in der Regel große Dimensionen und ein komplexes Design. Große Bauteile und komplexe Formen lassen sich mit Composites in einem Bauteil darstellen, mehrstufige Verarbeitungsprozesse entfallen. Dies sind nur einige der Vorteile, die durch den Einsatz von Composites entstehen können. Die Experten des AVK-Arbeitskreises waren sich einig: die Elektromobilität bietet vielfältige Chancen für Composites. Man muss als Industrie die sich bietenden Möglichkeiten gemeinsam angehen, um von den anstehenden Änderungen profitieren zu können. Darüber hinaus muss die Vorteilhaftigkeit der Materialien zukünftig noch besser nach außen und zu potenziellen Nutzern/Anwendern kommuniziert werden.

Deswegen wurde entschieden, die Arbeit gemeinsam fortzusetzen. Ein nächstes Treffen des Arbeitskreises „Werkstoffeigenschaften und -anforderungen für die E-Mobilität“ wird am 24.06.2021 stattfinden.
