Die Schwerpunkte liegt dabei auf den Branchen Chemie, Kunststoffe und der Circular Economy.

Die aktuellen Ergebnisse der Studie »resources SAVED by recycling« belegen die positive Wirkung der Kreislauflösungen erneut. Interzero hat 2021 die Umwelt erheblich entlastet. Durch die Kreislaufführung von insgesamt 1,8 Millionen Tonnen Wertstoffen konnte Interzero im Jahr 2021 mit seinen Kunden rund 12,5 Millionen Tonnen Primärressourcen einsparen. Zudem konnte der Ausstoß von rund einer Million Tonnen Treibhausgasen vermieden werden. Ohne den Einsatz von Interzero wären das Kosten für klimabedingte Umweltschäden in Höhe von 199 Millionen Euro (gemäß Umweltkostenermittlung des Umweltbundesamtes). Die aktuelle Einsparung an Primärressourcen entspricht dem Gewicht von 5.227 ausgewachsenen Mammutbäumen.

Die genauen Ergebnisse der aktuellen Studie stellt Interzero auf der »K 2022« vom 19. bis 26. Oktober in Düsseldorf vor. Auf der Kunststoffmesse präsentieren die Expertinnen und Experten von Interzero Plastics Recycling innovative Technologien und Services für das Kunststoffrecycling und erläutern die Umweltvorteile des Recyclings gegenüber der Primärproduktion. So haben die Forschenden des Fraunhofer UMSICHT errechnet: Der Einsatz des von Interzero produzierten Recyclingkunststoffs Procyclen spart beispielsweise im Vergleich zu Primärkunststoffen aus Rohöl 56 Prozent klimaschädliche Emissionen ein.

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.

BB Engineering has been focusing its development work increasingly on recycling technologies for several years. In addition to extruders, filters and mixers that are suitable for both recycling processes and the processing of recyclate, BB Engineering offers a complete PET recycling plant called VacuFil.

With VacuFil, BB Engineering has developed an innovative PET LSP recycling process. The process combines gentle large-scale filtration and targeted IV regulation for consistently outstanding rPET melt quality. Thus, much more than simple "downcycling" is possible with VacuFil. VacuFil processes a wide range of input materials - post-production and post-consumer. The patented key component Visco+ vacuum filter removes volatile impurities quickly and reliably. VacuFil is a modular system that can be designed for different recycling applications. Simple granulation is possible, but also direct feeding into further processing, e.g. in the synthetic fiber spinning mill. BBE offers VacuFil in combination with its own VarioFil compact spinning plant to produce polyester yarn.

At the K show 2022, visitors can experience the VacuFil Visco+ recycling technology in operation with a connected VarioFil spinning plant and see live how recycling yarn is produced from PET waste.

The Oerlikon Barmag eccentric screw pump
02.06.2022

Oerlikon Barmag presents innovations at the ACHEMA 2022

Focus on eccentric screw pumps and pumps for shear-sensitive materials

Improved productivity and increased lifespan and tailored solutions also for the most demanding applications within the chemicals and plastics industries and in PUR applications – these are the convincing arguments with which Oerlikon Barmag is showcasing its precision metering pumps at this year’s ACHEMA between August 22 and 26, 2022 in Frankfurt. The focus is on the new pump for shear-sensitive conveying media and the new eccentric screw pump.

Focus on eccentric screw pumps and pumps for shear-sensitive materials

Improved productivity and increased lifespan and tailored solutions also for the most demanding applications within the chemicals and plastics industries and in PUR applications – these are the convincing arguments with which Oerlikon Barmag is showcasing its precision metering pumps at this year’s ACHEMA between August 22 and 26, 2022 in Frankfurt. The focus is on the new pump for shear-sensitive conveying media and the new eccentric screw pump.

Eccentric screw pumps – robust all-rounders convey any medium
The requirements for pumps are considerable, as the demand for customized solutions for increasingly complex processes is rising. This is particularly true for Oerlikon Barmag’s new eccentric screw pump range. High wear-resistance, increased durability and robust operation – the new pump is tailor-made for conveying highly-filled, high-viscosity and abrasive media, such as filled adhesives, filled silicones and filled casting compounds, for example. The is the multi-stage seal system, which considerably increases the pump’s lifespan. The upstream shaft sealing ring protects the slide ring seal against excessively-fast wear caused by challenging media. In turn, the optimum alignment of the drive shaft – ball bearing-supported and centrally-guided through the shaft sealing ring – prevents any metal debris caused by friction and hence ensures considerably greater durability. Producers benefit from considerably greater productivity, as the pumps’ maintenance intervals and hence machine downtimes are significantly reduced.

New pump for shear-sensitive materials
For increasingly complex customer-specific process solutions, Oerlikon Barmag is now expanding its GA series, developed especially for the challenging conveying of high-viscosity media, to include the GAB51F for shear-sensitive conveying media. The newly-developed pump with its viscosity range of max. 300 Pas is tailored to conveying high-viscosity, shear-sensitive materials such as adhesives and silicones, for example. “The shear forces impacting the medium within the pump are reduced to a minimum as a result of a specially geometry”, explains Thorsten Wagener, Senior Sales Manager within the Pump Construction business unit. The material is conveyed through the pump in an as gentle and low-pulsation manner as possible and metered precisely at the outlet – ensuring it retains its characteristic properties.

High-speed metering pump with sealed product space
The high-speed metering pump has been especially developed for metering poorly-lubricating media. Here, the main benefit is the sealed product space, which extends the pump’s lifespan considerably. The space that comes into contact with the media is limited to the area around the gears. “As a result, the high-speed pump is particularly suited for applications in the chemicals industry, which frequently involve aggressive acids”, comments Thorsten Wagener.

GM series for low-viscosity media
The pumps in the GM and GA series provide precision metering with low-pulsation feeding of the conveying medium. The multi-stage GM pump conveys low-viscosity media (i.e. 250 bar, 100 mPas) even under high pressure and in the most challenging conditions. The square design from the proven GM series is the standard pump for many metering tasks. The development of the multi-stage pump expands the applications range for the GM series considerably. The round 2-stage GM pump has been developed especially for use in high-pressure technology. It masters the particular challenge of conveying small throughputs with low viscosities. The pump is perfect for 0.05 through 20 cm³/rev feed sizes and is excellently suited for use in high-pressure machines for PUR molded parts, foam slab stock, refrigeration unit insulations and sandwich panels, for example.

GA series pumps for high-viscosity media
The Oerlikon Barmag GA range has been especially developed for the challenging conveying of media with higher viscosities. The GA series pumps are available for conveying volumes of between 1.25 and -30 cm³/rev (0.6-144 l/h). They have been designed for pressures of up to 200 bar, for viscosities of up to 1.500 Pas as well as for temperatures of up to max. 225 °C. With this range of pumps, Oerlikon Barmag offers its customers tailor-made solutions for many technical processes in which high-precision and even metering is of paramount importance.

The drum pump – conveying and metering using a single unit
With the drum pump, the Oerlikon Barmag pump specialists have created a pump designed specifically for conveying and metering high-viscosity materials such as adhesives, silicones and other high-viscosity materials from drums and other large containers and for pressures of up to 250 bar. Its special features not only include the fact that it removes high-viscosity materials from the drum, but that it also meters the medium directly without any additional interim stops.

Fraunhofer UMSICHT: Marktfähige Power-to-X-Technologien entwickeln

Im Rahmen eines neuen Projektes des Spitzenclusters Industrielle Innovationen (SPIN) entsteht eine offene Versuchsplattform für die Entwicklung von Power-to-X-Technologien. Untersucht werden dabei Möglichkeiten, CO2-haltige Abgasströme zunächst in ein Synthesegas aus Kohlenmonoxid und Wasserstoff und dann in verschiedene Produkte für die Chemie-, Kraftstoff- und Kunststoffindustrie umzuwandeln. Die nordrhein-westfälische Landesregierung fördert dieses Vorhaben mit 5,3 Mio. Euro.

Im Rahmen eines neuen Projektes des Spitzenclusters Industrielle Innovationen (SPIN) entsteht eine offene Versuchsplattform für die Entwicklung von Power-to-X-Technologien. Untersucht werden dabei Möglichkeiten, CO2-haltige Abgasströme zunächst in ein Synthesegas aus Kohlenmonoxid und Wasserstoff und dann in verschiedene Produkte für die Chemie-, Kraftstoff- und Kunststoffindustrie umzuwandeln. Die nordrhein-westfälische Landesregierung fördert dieses Vorhaben mit 5,3 Mio. Euro.

Die Federführung des Projektes »PtX-Plattform« liegt bei der Mitsubishi Power Europe GmbH. Gemeinsam mit SPIN sowie den Projektpartnern – dem Fraunhofer UMSICHT, dem Lehrstuhl für Umweltverfahrenstechnik und Anlagentechnik (LUAT) der Universität Duisburg-Essen sowie Evonik Industries – will das Unternehmen marktfähige Lösungen für die effiziente Nutzung überschüssigen Stroms entwickeln. Ein Schwerpunkt werden dabei Wasserstoff- sowie Carbon-Capture-Use-and-Storage-Technologien sein: CCU und CCS. Entsprechende containerbasierte Anlagen entstehen auf dem Gelände des LUAT. Sie umfassen u.a. CO2-Abtrennung und katalytische Co-Elektrolyse und stellen alle notwendigen Energie- und Stoffströme zur Verfügung.

Elektrolytische Herstellung von Synthesegas
Das Fraunhofer UMSICHT erarbeitet im Zuge des Projektes u.a. Grundlagen, um in einem Power-to-X-Reaktor die elektrolytische Herstellung von Synthesegas im Labormaßstab zu demonstrieren. »Dazu skalieren wir neuartige Gasdiffusionselektroden und setzen sie für die Aufgabe in angepassten Reaktoren ein«, erklärt Prof. Dr. Ulf-Peter Apfel, Leiter der Abteilung Elektrosynthese. »Weitere Komponenten der Elektrolysezellen werden so aufeinander abgestimmt, dass Verlustleistungen und Gasleckagen minimiert sowie die Zusammensetzung des Synthesegases möglichst kontrolliert variiert werden können.« Neben der Erstellung der erforderlichen Komponenten führt das Institut auch die Entwicklung, Errichtung und Inbetriebnahme eines skalierten Elektrolysesystems (inkl. der Teststandperipherie) durch und integriert alles in die Containerumgebung der Plattform.

Charakterisierung von Katalysatoren
Darüber hinaus testen die Wissenschaftlerinnen und Wissenschaftler des Fraunhofer UMSICHT Katalysator-Systeme, die neu von Evonik entwickelt worden sind und bei der Synthese von Alkoholen zum Einsatz kommen. »Wir schauen uns Umsatz, Menge und Konzentration sowohl der auftretenden Produkte als auch der Nebenprodukte an und haben dabei vor allem die Lebensdauer des Katalysators im Blick«, so Prof. Apfel. »Auf Basis unserer Testergebnisse nimmt Evonik dann weitere Optimierungen der Katalysatoren sowie deren Scale-up in Angriff.« Das beste System wird dann für den Pilotreaktor ausgewählt.

Die Bedeutung des Projektes hob Prof. Dr. Andreas Pinkwart bei der Übergabe des Förderbescheids hervor. »Die aktuellen Ereignisse zeigen einmal mehr, wie wichtig eine sichere und unabhängige Energieversorgung ist«, betonte der NRW-Minister für Wirtschaft, Innovation, Digitalisierung und Energie. »Eine zukunfts- und wettbewerbsfähige Industrie benötigt große Energiemengen und klimaneutral erzeugte Rohstoffe für ihre Produktionsprozesse. Power-to-X kann nicht nur dazu beitragen, dass wir unsere ehrgeizigen Klimaschutzziele erreichen, sondern auch zu einer unabhängigen Versorgung mit synthetischen Kraftstoffen und Chemikalien für unsere Industrie und unser Energiesystem der Zukunft.«

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.

Fraunhofer UMSICHT: Carbon Management Strategie NRW

Zahlreiche Produkte unserer Industriegesellschaft wie Stahl, Aluminium, Zement oder Kunststoff bestehen aus Kohlenstoff oder benötigen ihn, um hergestellt werden zu können. Zentrale Ansätze, wie der Umgang mit Kohlenstoff neu und nachhaltig gestaltet werden kann, hat das Ministerium für Wirtschaft, Innovation, Digitalisierung und Energie (MWIDE) mit der Carbon Management Strategie NRW vorgelegt. Ziel ist eine klimaneutrale Industrie. Auf einer gemeinsamen Veranstaltung des Thinktanks IN4climate.NRW und des MWIDE hat Wirtschafts- und Energieminister Prof. Andreas Pinkwart mit Expert*innen aus Industrie, Wissenschaft und Zivilgesellschaft die Inhalte diskutiert.

Ziel ist eine klimaneutrale Industrie. Auf einer gemeinsamen Veranstaltung des Thinktanks IN4climate.NRW und des MWIDE hat Wirtschafts- und Energieminister Prof. Andreas Pinkwart mit Expert*innen aus Industrie, Wissenschaft und Zivilgesellschaft die Inhalte diskutiert.

»Für uns ist klar: Kohlenstoff kann Klimaschutz«, so Minister Pinkwart. »Mit unserer Carbon Management Strategie zeigen wir ganz konkret, wie eine klimaneutrale Kohlenstoffwirtschaft in Nordrhein-Westfalen aussehen kann. Wir wollen Kohlenstoff nicht nur reduzieren, sondern auch nachhaltig so oft wie möglich im Kreislauf nutzen und die Gesellschaft transparent einbinden. Wir sind damit das erste Bundesland überhaupt, das sich dem Thema annimmt. So können wir unsere ehrgeizigen Klimaschutzziele erreichen und den Industriestandort von morgen gestalten.«

Eine klimaneutrale Industrie braucht nachhaltige Kohlenstoffquellen
Dr. Iris Rieth, Projektmanagerin für Kohlendioxidwirtschaft und Circular Economy bei IN4climate.NRW: »Eine klimaneutrale Industrie braucht nachhaltige Kohlenstoffquellen. Die Circular Economy und die Nutzung von CO2, dessen Ausstoß nicht vermieden werden kann, müssen wir weiter ausbauen. IN4climate.NRW hat in enger Zusammenarbeit mit Unternehmen und der Wissenschaft wichtige Ansätze erarbeitet, die den unterschiedlichen Industrieprozessen gerecht werden. Die Carbon Management Strategie führt nun die Bausteine der Transformation zusammen und setzt die notwendigen politischen Leitplanken, an denen wir uns in unserer weiteren Arbeit orientieren können.«
Infrastruktur für den Transport von CO2 muss aufgebaut werden

Kohlenstoffdioxid war bislang kein Bestandteil von Infrastrukturplanungen in Deutschland. Dabei wird es auch in Zukunft Prozesse geben, bei denen unvermeidlich CO2 entsteht, wie etwa bei der Herstellung von Zement. Verschiedene Projekte arbeiten bereits daran, CO2 direkt am Ofen abzufangen und anderen Branchen, vor allem der chemischen Industrie, als Rohstoff zur Verfügung zu stellen (engl. Carbon Capture and Utilisation, CCU). Eine Infrastruktur für den Transport muss jedoch erst noch aufgebaut werden.

Konkrete Optionen, wie ein solches Pipeline- und Transportsystem aussehen könnte, hat IN4climate.NRW Mitte Oktober in dem Diskussionspapier »CO2 in einer klimaneutralen Grundstoffindustrie« veröffentlicht. In einem weiteren Diskussionspapier »Circular Economy in der Grundstoffindustrie« hat IN4climate.NRW zudem aktuelle Stoffströme analysiert und Lösungsansätze für eine zukünftige industrielle Circular Economy erarbeitet. Beide Papiere sind maßgeblich in die Carbon Management Strategie des Landes eingeflossen.

An der Paneldiskussion haben neben Wirtschafts- und Energieminister Prof. Andreas Pinkwart teilgenommen:

  • Dr. Iris Rieth, Projektmanagerin für Kohlendioxidwirtschaft und Circular Economy bei IN4climate.NRW,
  • Prof. Görge Deerberg, stellvertretender Institutsleiter des Fraunhofer UMSICHT,

GRAFE: Plagiarism Protection with Marking Substances in the Plastic Matrix

To ensure product protection and prevent brand piracy, GRAFE has developed a simple and elegant solution that also offers a high level of security. The basis is special markers. "The highly complex pigments with special physical properties designed for this purpose are used in minute quantities within the plastic matrix. With an appropriately calibrated detector, products equipped with them can thus be read and authenticated," explains Business Development Manager Florian Ludwig. At the same time no changes in properties can usually be observed. The detectors can use an LED display to check within seconds whether the unique marker is contained in the product and whether this item is the original product.

The detectors can use an LED display to check within seconds whether the unique marker is contained in the product and whether this item is the original product.

In general, there are two options: x ray and light fluorescence, i.e. fluorescent X-rays or light. With the first option, the base color has no influence (not even black) and the customer benefits from low addition dosage and batch price, but this method requires higher investment. "With light fluorescence, on the other hand, detection is done by a measuring device, which is preconfigured by our partner or by us directly. Different types are available, from handy hand-held measuring devices to stationary office solutions to inline spectrometers, in order to have a control take place directly during production," Ludwig explains. With this method, the masterbatch dosage is based on the base color, among otherv things. The method of operation is fast and simple, and the necessary investment is also manageable.

From injection molding and extrusion to transparent and fiber applications, almost all areas of plastics processing come into question.

Borealis announces that it has entered into a multi-dimensional partnership with Renasci N.V., a provider of innovative recycling solutions and creator of the novel Smart Chain Processing (SCP) concept. The partnership is another key enabler for Borealis to realise its ambitions to bring circular base chemicals and polyolefins to market, and to deliver on its promise to bring 350 kilotons of recycled polyolefins into circulation by 2025.

SCP concept leaves no waste behind
The SCP concept developed by Renasci is a proprietary method of maximising material recovery in order to achieve zero waste. It is unique because it enables the processing of multiple waste streams using different recycling technologies – all under one roof. At the newly-built Renasci SCP facility in Oostende, Belgium, mixed waste – plastics, metals, and biomass – is automatically selected and sorted multiple times.

After sorting, plastic waste is first mechanically recycled, and then in a second step any remaining material is chemically recycled into circular pyrolysis oil and lighter product fractions, which are used to fuel the process.

Other types of sorted waste such as metals and organic refuse are further processed using other technologies. In the end, only 5% of the original waste remains, and even this residual material is not landfilled, but used as filler in construction materials. Because of this extremely efficient way of processing, the overall CO2 footprint of these waste streams is greatly reduced – yet another advantage of the circular SCP concept.

The cascade model is Borealis’ integrated circular approach
Borealis circular cascade model sits at the heart of its ambition to achieve a truly circular economy, by combining carefully chosen technologies in a complementary and cascading way to achieve full circularity. In this way, Borealis aims to give plastic products multiple lifetimes in the most sustainable way possible. Starting with optimising product design, first for eco-efficiency, then for re-use and finally for recycling. Once a product has reached its end of life, we must close the plastics loop: first with mechanical recycling to make products with the highest possible value, quality and lowest carbon footprint; then utilising chemical recycling, as a complement to mechanical recycling, to further valorise residual streams which would otherwise go to incineration, or even worse to landfills. The valorised material from mechanical and chemical recycling is then processed with Borealis Borcycle™ recycling technology consisting of Borcycle M for mechanical recycling and Borcycle C for chemical recycling, providing high quality solutions for more sophisticated applications, such as food packaging and healthcare.

The SCP concept is aligned to Borealis’ ambition to close the loop on plastic waste as encapsulated in its circular cascade model.

Wie lässt sich die Wiederverwertung von Kunststoffen ausweiten und weiter verbessern? Antworten darauf haben Forschungsinstitute der Zuse-Gemeinschaft. Expertise in Sachen Kunststoffe ist in zahlreichen der bundesweit mehr als 70 Institute stark vertreten.

Kunststoffe lassen sich am besten wiederverwerten, wenn sie nicht nur sortenrein getrennt zur Verfügung stehen, sondern sich auch in ihren Ausgangsstoffen gleichen. Allerdings geben Unternehmen ungern die sensiblen Daten ihrer Rezepturen preis. Hier setzt ein Projekt des Kunststoff-Zentrums SKZ an. Ohne die einzelnen Zutaten der Kunststoffe zu kennen, erfassen die Würzburger Wissenschaftler in einem neuen, von der EU geförderten Kooperationsprojekt, wichtige Messgrößen bei der Produktion wie Temperatur, Druck und Fließeigenschaften des Materials, die mittels digitaler Technologien für die Wiederverwertung bereitgestellt werden. „Wir entwickeln einen digitalen Werkzeugkasten, so dass die einzelnen, in der Neuware verwendeten Inhaltsstoffe nicht unbedingt bekannt sein müssen, um später ein hochwertiges Recycling-Produkt herzustellen“, erläutert Dr. Hermann Achenbach vom Geschäftsfeld Nachhaltigkeit des SKZ. So kann Recycling künftig schon verstärkt beginnen, bevor das Produkt aus Neuware überhaupt vermarktet ist. Das SKZ-Projekt zielt nämlich vor allem auf Reste aus der Produktion und gewerbliche Abfälle.
