From the Sector

Trevira CS is exhibiting for the first time at CSI Miami (Cruise Ship Interiors Design Expo Americas). Taking place on 6 – 7 June, 2023 at the Miami Beach Convention Center, CSI will bring together buyers and suppliers involved in cruise ship interiors, including interior designers, architects, outfitters, shipyards and suppliers.
 
On the Trevira CS stand, visitors can get an idea of the wide range of flame retardant fabrics suitable for use on board cruise ships. 53 fabrics from 20 Trevira CS customers will be on display that either have IMO certification and/or have been tested to the fire safety standards (FTP Code) required in the marine sector. Trevira CS fabrics are inherently flame retardant, meaning that their flame retardant properties cannot be washed out or lost through aging or use. This is due to the chemical structure of the polyester fiber: the flame retardant properties are firmly anchored in the fiber and cannot be altered by external influences. A surface-applied flame retardant finish is therefore not necessary.

In the marine sector, the demands placed on textiles are not only high in terms of fire protection, but also with regards to light resistance and durability. This is particularly true for textiles used in outdoor applications. These must be extremely robust, as they are exposed to moisture and sunlight. To meet these requirements, Trevira CS has launched a range of 30 new spun-dyed, UV-stable filament yarns. Besides color depth and durability, spun-dyed yarns offer another advantage: They are more sustainable because the fabrics made from them can be produced in a more environmentally friendly way than textiles that are dyed in one piece or consist of brightly colored yarns. In fabric production, a large share of resource consumption goes to the dyeing and finishing of fabrics as well as the use of chemicals and water. However, with spun-dyed yarns, these processing steps are unnecessary – the yarn immediately comes out of the spinneret in the desired color, reducing the products’ environmental impact.

The topic of sustainability is also taken up in other Trevira CS products. For example, Trevira CS fabrics are available in recycled versions. They consist of fiber and filament yarns obtained in different recycling processes. Filament yarns are produced using recycled PET bottles, they contain 50% post-consumer recycled material. Recycled fibers are obtained using an agglomeration plant and in further processing steps from residual pre-consumer waste from production. They consist of 100% recycled material (pre-consumer recycling). All flame retardant recycled Trevira® products are GRS (Global Recycled Standard) certified.
Fabrics made from these yarns are marked with the Trevira CS eco trademark. The prerequisite for this is a recycled content of at least 50%. Among the fabrics presented at the Trevira CS trade fair stand are 8 fabrics bearing the Trevira CS eco brand.

The long-term goal in developing sustainable products is undoubtedly to enter a circular economy. For this new path, an innovative Trevira CS product development was launched, producing flame retardant fibers and filament yarns from chemically recycled raw material. In this case, the basic raw material for the chemical recycling was PET bottles, but essentially it could be most any other PET recyclables, such as packaging material or even textiles. Chemical recycling involves depolymerization, a sequence of chemical reactions in which the polymer chains are broken down again into their original components, i. e. the monomers. In a further processing step, impurities are removed. Before the polymerization process is initiated, a small amount of MEG (mono ethylene glycol) is added.

The same technology used to produce the original (virgin) raw material for Trevira CS is also used here. The flame retardant modification is added during polymerization. In this way, the flame retardant properties are indelibly anchored in the polymer.

By recycling valuable materials such as packaging material, waste can be avoided. The raw material obtained from the recycling process is comparable to the original material can be used again in high-quality products.

Start für ein EU-weites Verbundprojekt: Unter der Leitung des französischen Unternehmens Fairbrics SAS finden sich 17 Projektpartner aus sieben europäischen Ländern zusammen. Gemeinsames Ziel ist es, in einem geschlossenen Kreislauf Endprodukte aus Polyester unter Verwendung von industriellen CO₂-Emissionen zu erzeugen und zur Marktreife zu führen. Die DITF stellen dabei Synthesefasern aus Kunststoffen nicht fossilen Ursprungs her.

Um die europäischen Klimaziele zu erreichen, müssen Treibhausgase langfristig und nachhaltig reduziert werden. CO₂-Emissionen müssen hierfür in der Energiewirtschaft, in der Industrie sowie bei Haushalten und Kleinverbrauchern gesenkt werden. Hieran knüpft das EU-weite Verbundprojekt ‚Threading CO2‘ an, welches im Rahmen des Horizon-Förderprogramms der EU finanziert wird. Bei dem Projekt werden Produkte aus umweltfreundlich hergestelltem Polyester (PET) in die Marktreife überführt.

Die technologische Grundlage hat Firma Fairbrics SAS aus Frankreich entwickelt. Es geht um die Herstellung von Monoethylenglycol (MEG), dem Ausgangsstoff für die Herstellung von Polyester, unter Verwendung von CO₂, das aus industriellen Abgasen gewonnen wird - ein neuer Ansatz, denn im klassischen Verfahren werden fossile Rohstoffe für die Produktion von Polyester verbraucht. Auf diese Weise wird nicht nur direkt die Freisetzung von CO₂ in die Atmosphäre verhindert. Das CO₂ trägt zusätzlich einer erhöhten Wertschöpfung bei, indem es bei der Erzeugung von hochwertigen textilen Produkten eingebunden wird. Der Kern des Projektes ist die technologische Aufskalierung des neuen MEG-Syntheseprozesses in Pilotanlagen, die den Weg für die industrielle Fertigung ebnen.

In dem EU-Verbundprojekt werden sich 17 Projektpartner mit ihrem speziellen Fachwissen einbringen und den Prozess technologisch weiterentwickeln und industriefähig machen. Die DITF Denkendorf übernehmen innerhalb des Konsortiums die Aufgabe, das Upscaling zu begleiten und den Schritt ‚vom Molekül zum Material‘ zu gehen: Aus dem nachhaltig hergestellten Monoethylenglykol werden in eigenen Laboratorien Polyester synthetisiert, zu Fasern versponnen, texturiert und weiterverarbeitet. Dabei soll überprüft werden, ob die Qualität des Polyesters sowie dessen Verspinn- und Verarbeitbarkeit in der textilen Wertschöpfungskette vergleichbar mit konventionellem Polyester ist.

Die Projektpartner Faurecia und Les Tissages de Charlieu verarbeiten die Fasern und Textilien zu Autositzen und Bekleidung, um die Qualität auch im Endprodukt beurteilen zu können. Die anschließende Rezyklierfähigkeit der Produkte wird an den DITF überprüft. Außerdem soll eine Sicherheitsmarkierung für diesen CO₂-basierten Polyester entwickelt werden, um ihn vor Produktpiraterie zu schützen.

• IVL commits to being an industry leader in sustainability under ‘Vision 2030’

Indorama Ventures Public Company Limited (IVL), a global sustainable chemical producer, today reported a record FY2021 performance as the economic recovery drove demand across the company’s global footprint. 

Mr Aloke Lohia, Indorama Ventures Group CEO, said: “In 2021 we proved the resilience of our global footprint and our integrated portfolio across the polyester value chain. The past two years were an unprecedented period of disruption in which our business model’s robustness and our teams’ agility were tested. Having reset our business plan for the ‘new normal’ era, I have never been more confident in our model, our strategy, and our teams."

2021 Summary

In 2021, IVL delivered Core EBITDA of US$1,743 million (up 55% YoY) on production volumes of 14.72 MMT (up 7% YoY). Consolidated Revenue increased 38% YoY to US$14,629 million as consumer confidence rebounded and the company’s resilient model benefited from rising inflation, energy price hikes and supply chain shocks.

Macroeconomic tailwinds supported IVL’s performance, including government stimulus packages. In premium western markets, higher freight rates improved the company’s local import parity pricing advantage. In the fourth quarter, the introduction of China’s dual control policy widened polyester margins. 

IVL’s largest Combined PET segment posted a 39% increase in Core EBITDA to US$1,103 million in the context of strong demand and low inventories. The resetting of PET contracts in 2022 is expected to capture higher freight rates and the consequent beneficial impact on import parity. The segment is expected to enjoy improved margins in 2022.

Integrated Oxides & Derivatives (IOD) recorded a Core EBITDA of US$377 million, up 228% from a year earlier. With higher oil prices expected to continue into 2022, the segment will continue to benefit from shale gas economics, improving MEG spreads, and upside from Lake Charles (IVOL) ethylene cracker, which resumed operations in late 2021. The Oxiteno acquisition, expected to close in H1 2022, will bring complementary products, green energy innovation, and geographical diversification to the IOD segment.

Fibers segment delivered a 37% increase in Core EBITDA of US$268 million as volumes rose 11%. Margins widened due to tighter markets and a favorable product mix, with setbacks coming from energy and commodity price increases, while the ongoing semiconductor shortage impacted the Mobility vertical.

Mr D K Agarwal, CEO and CFO at Indorama Ventures, said: “The performance was a result of a number of important macroeconomic factors, such as heightened crude oil prices, supply disruptions, and resurgent consumer confidence as vaccinations were rolled out in the pandemic’s second full year. These factors led to improved margins and benefited us as a preferred regional supplier that can react quickly to fulfill our customer needs. Our transformation programs that we started three years ago are also delivering efficiency gains faster than planned. As the world emerges from the pandemic, our increased confidence in IVL’s resilient model sets a strong foundation for further growth through 2024.”
