From the Sector

Autoneum carpet systems already meet high standards of sustainable mobility due to their high content of recycled fibers. Thanks to an alternative backcoating (ABC) process, Autoneum carpets are now becoming even more environmentally friendly: By replacing the latex commonly used in standard backcoatings with thermoplastic material, the recyclability of carpets at the end of product life is further  improved. In addition, the innovative manufacturing process greatly reduces water and energy consumption and thus CO2 emissions in production.

Lightweight, textile-based carpet technologies such as Di-Light or Relive-1 significantly improve the environmental performance of carpets. For example, Di-Light-based carpets consist of up to 97% recycled PET; aside from that, they are around 20% lighter than conventional needlepunch carpets, thus contributing to lower fuel consumption and CO2 emissions from vehicles. In addition, Autoneum needlepunch carpets are now even more sustainable thanks to the innovative ABC process, which uses a thermoplastic adhesive instead of latex in the backcoating: Unlike latex, thermoplastic adhesives can be heated and melted down together with the carpet components made of pure PET at the end of the product life cycle, which facilitates recycling considerably. Furthermore, since the fibers of the thermoplastic mono-material are easier to open, carpet cut-outs can be reclaimed more easily, thereby reducing the consumption of natural resources as well as waste volumes and thus CO2 emissions. The environmental  performance of Autoneum’s needlepunch carpets, which already contain a high proportion of recycled PET, is thus further improved.

Moreover, backcoatings without latex improve the sustainability of carpets not only thanks to better recyclability at the end of the product life cycle. Since the application of the thermoplastic adhesive using the innovative ABC process consumes significantly less energy than the production of latexbased backcoatings and does not require any water at all, the environmental impact can already be minimized in the manufacturing process. Additionally, thermoplastic adhesives developed in-house by Autoneum will open up new possibilities in the future for adapting backcoatings to the individual needs of vehicle manufacturers in terms of their acoustic performance, stiffness and abrasion resistance.

Models from various customers in Europe and North America are already equipped with latex-free needlepunch carpets from Autoneum. In the near future, backcoatings with thermoplastic adhesives will also be used for Autoneum’s tufted carpets. Production of the new, even more sustainable generation of tufted carpets is scheduled to start in early 2022.

Technologies with an excellent environmental performance throughout the entire product life cycle – that is what “Autoneum Pure.” stands for. In future, components that meet the highest standards in terms of sustainability and eco-friendliness can be identified at a glance under this label. This also includes the innovation “Mono-Liner” for wheelhouse outer liners.

As innovation leader in acoustic and thermal management, Autoneum continuously invests in the development and production of resource-saving components that make cars lighter and thus more climate-friendly. In view of an increasing sustainability awareness and the correspondingly greater information needs on environmentally-friendly vehicle components, the Company has now launched Autoneum Pure. The label determines particularly sustainable technologies, thereby guiding car manufacturers in product selection for future models.

Autoneum Pure is based on a comprehensive set of criteria assessing the sustainability performance of a product in all four phases of its life cycle: material procurement, production, use and end of life. For example, components with a high content of recyclable materials or those that achieve significant weight savings compared to comparable standard components qualify for the “Autoneum Pure.” label. Autoneum already offers various multifunctional technologies that meet the high standards for Autoneum Pure products: Ultra-Silent for underbody systems or battery undercovers, Di-Light for carpet systems, Prime-Light and IFP-R2 for inner dashes and floor insulators as well as Hybrid-Acoustics PET for e-motor encapsulations and engine-mounted parts, which was launched in fall 2019.

With Mono-Liner, the latest innovation for wheelhouse outer liners is also included in the Autoneum Pure portfolio. Among other things, the Mono-Liner-based components convince thanks to their lightweight construction, thereby contributing to lower vehicle weight with correspondingly less fuel consumption and emissions. The excellent life cycle assessment is also based on their particularly resource-saving manufacturing: Production cut offs of the components, which consist to a large extent of recycled PET fibers, can be processed into pellets and completely returned to the manufacturing process as fibers. An SUV and a crossover model from a US vehicle manufacturer already benefit from Mono-Liner wheelhouse outer liners.

Anahid Rickmann, Head of Corporate Communications & Responsibility, explains: “With Autoneum Pure we are the first automotive supplier to establish a sustainability label in the field of acoustic and thermal management. Autoneum Pure is part of the Company's Advance Sustainability  Strategy 2025 and sets industry standards in product communication.”

Bobingen - On the 4th October 2017 a new brand was introduced at Trevira: Trevira SINFINECO®. This label may be carried by all textiles that contain sustainable Trevira products. Sustainable, innovative, high-value and responsible – these are the values the new brand stands for.

As an industrial enterprise, Trevira is conscious of its special responsibility for an intact environment and has long advocated the recycling of valuable raw materials and waste products. Trevira CEO Klaus Holz: “We at Trevira wish to preserve the environment and at the same time work to create value. These are the criteria of our sustainability concept.“

Creation of the new brand is therefore only a logical step, one that enables customers to label their sustainable Trevira products as such. Trevira is known for the high quality of its products. In every way recycled products are as good as the original materials in terms of quality and performance.

Two vital elements in Pre-Consumer Recycling and an important concept in Post-Consumer Recycling form part of the sustainability strategy of Trevira to conserve resources and maintain value. :

In the area of Pre-Consumer Recycling, on the one hand, residual materials resulting from the manufacture of polyester fibres and filaments in Bobingen and Guben, dependent on the manufacturing step, are processed in the agglomeration plant and restored to become serviceable primary material. The recyclates are then fed back to our fibre and filament spinning mills, to be made into new top-quality products.

On the other hand, in fibre production there occurs in the manufacture of tow a small proportion of tow that cannot be used for converting and has to be cut out. Instead of selling this material as waste, it is cut up, pressed into balls and then carded / combed by a partner, resulting in a 1A quality product. The GRS certification (Global Recycled Standard) is requested for this. As with converter tow from new material, the recycled tow is mostly incorporated into polyester wool blends (55 % PET / 45 % wool), which are used primarily in corporate wear and uniforms.

In the area of Post-Consumer Recycling, Trevira offers filament yarns consisting of 100 % recycled PET bottles. Our parent company Indorama manufactures very high quality recycled chips from PET bottles. Since only transparent PET bottles are used in Thailand, the flakes and chips are of a particularly good and very uniform quality. The recycled chips, fibres and filaments from Indorama bear the GRS certificates (Global Recycled Standard) and RCS-NL (Recycled Claim Standard). Trevira processes the regranulate made by Indorama from bottle flakes into filament yarns consisting 100 % of recycled material. The filament yarns are available in titres 167 and 76 dtex normal polyester. Alongside technical applications, they are used in the automotive and apparel sectors. In addition, many promising developments with the recycled material are on their way.
