From the Sector

With the fully recyclable 100% polyester trunk side trim, Autoneum is putting the rear of the vehicle at the center of its efforts for a more circular economy in the automotive industry. The latest addition to Autoneum’s growing portfolio of sustainable monomaterial products made entirely from polyester is based on the existing Pure technology Propylat PET. The component demonstrates an excellent environmental performance in terms of recycled content, waste-free manufacturing and end-of-life recyclability.

New regulations such as the revised End-of-Life Vehicles Directive in Europe are accelerating the automotive industry’s transition from a linear to a circular economy. In this context, the recyclability of vehicles at the end of their service life is becoming increasingly important. This in turn raises the demand for automotive components that have an excellent environmental performance across the product life cycle and at the same time meet the highest standards of material quality and technical performance. Autoneum’s new 100% polyester trunk side trim helps customers achieve their ambitious sustainability targets while offering optimum durability, design flexibility and aesthetics.

As with Autoneum’s environmentally friendly monomaterial carpet systems, the new 100% polyester trunk side trim is fully recyclable. Production cut-offs can be reclaimed, processed and reused, ensuring a closed material loop. Thanks to Autoneum’s high-value recycling concept, the recycled fibers can also be granulated and spun into new fibers, which reduces the need for virgin raw materials and thus conserves natural resources. The carrier material is based on the lightweight Autoneum Pure technology Propylat PET and contains at least 50% recycled fibers. Like all variants of Propylat, the technology features a high proportion of recycled material and can be produced waste-free thanks to its complete vertical integration. In addition, Propylat PET consists of 100% PET and is therefore fully recyclable. The new monomaterial trunk side trim made exclusively from polyester is also available under the Autoneum Blue sustainability label. Blue products feature at least 30% recycled PET that was collected from coastal areas, thus making an important contribution to preventing plastic pollution in the oceans.

Autoneum’s sustainable concept for 100% polyester trunk components is not limited to side trim but can also be applied to tailgate and other trunk trim. Thanks to their unique material composition, the Propylatbased trunk trim parts are lightweight and sound-absorbing, thus contributing to the attenuation of tire and rear e-motor noise. In addition, their geometry can be tailored to individual customer needs while the textile surface improves the overall aesthetic of the parts and at the same time offers a high resistance to scratches. Autoneum’s eco-friendly 100% polyester trunk trim is available in Europe, North America and China.

Freudenberg Performance Materials (Freudenberg) is showcasing solutions for the automotive, building, apparel, filtration and packaging industries at this year’s Techtextil in Frankfurt am Main from April 23 – 26.

Sustainable nonwoven for car seats
One innovation highlight at Techtextil is a novel Polyester nonwoven material for car seat padding. Also available as a nonwoven composite with PU foam, it is not only easier for car seat manufacturers to handle during the mounting process, but also ensures better dimensional stability as well as providing soft and flexible padding. It has a minimum 25 percent recycled content, for example, by reusing nonwoven clippings and waste, and is fully recyclable. Full supply chain transparency enables customers to trace and verify the content of the nonwoven and thus ensures a responsible production process. The Freudenberg experts will also be presenting several other nonwoven solutions made of up to 80 percent recycled materials that can be used in car seat manufacturing.

Biocarrier for green roofs
Freudenberg is showcasing a sustainable carrier material for green roofs on urban buildings at the trade fair. The carrier is made from polylactide, i.e. from renewable resources. When filled with soil, it provides a strong foothold to root systems, enabling the growth of lightweight sedum blankets that can be rolled out to provide instant green roofs. These roofs not only help counter urban heat, they also improve stormwater management and regulate indoor temperatures.

From textile waste to padding
The company extended its circular thermal wadding product range with the release of comfortemp® HO 80xR circular, a wadding made from 70 percent recycled polyamide from discarded fishing nets, carpet flooring and industrial plastic. Because polyamide 6, also known as nylon, retains its performance characteristics after multiple recycling processes, the fibers can be used again and again to manufacture performance sporting apparel, leisurewear and luxury garments.

Packaging solutions with various sustainability benefits
Freudenberg is also showcasing products for sustainable packaging and filtration solutions. The long-lasting Evolon® technical packaging series is a substitute for disposable packaging used in the transport of sensitive industrial items such as automotive parts. The material is made from up to 85 percent recycled PET. A further highlight at Techtextil are Freudenberg’s fully bio-based solutions for manufacturing dessicant bags. The binder-free material based on bio-fibers is also industrially compostable.
In addition, the experts will be giving trade fair visitors an insight into Freudenberg’s filtration portfolio.

A new research project links some of Denmark's leading researchers in PFAS remediation with artificial intelligence. The goal is to develop and optimise a new form of wastewater and drinking water treatment technology using artificial intelligence for zero-pollution goals.

In a new research and development project, researchers from Aarhus University aim to develop a new technology that can collect and break down perpetual chemicals (PFAS) in one step in a purification process that can be connected directly to drinking water wells and treatment plants.

The project has received funding from the Villum Foundation of DKK 3 million, and it will combine newly developed treatment technology from some of Denmark's leading PFAS remediation researchers with artificial intelligence that can ensure optimal remediation.

"In the project, we will design, construct and test a new, automated degradation technology for continuous PFAS degradation. We’re also going to set up an open database to identify significant and limiting factors for degradation reactions with PFAS molecules in the reactor," says Associate Professor Xuping Zhang from the Department of Mechanical and Production Engineering at Aarhus University, who is co-heading the project in collaboration with Associate Professor Zongsu Wei from the Department of Biological and Chemical Engineering.

Ever since the 1940s, PFAS (per- and polyfluoroalkyl substances) have been used in a myriad of products, ranging from raincoats and building materials to furniture, fire extinguishers, solar panels, saucepans, packaging and paints.

However, PFAS have proven to have a number of harmful effects on humans and the environment, and unfortunately the substances are very difficult to break down in nature. As a result, the substances continuously accumulate in humans, animals, and elsewhere in nature.

In Denmark, PFAS have been found in drinking water wells, in surface foam on the sea, in the soil at sites for fire-fighting drills, and in many places elsewhere, for example in organic eggs. It is not possible to remove PFAS from everything, but work is underway to remove PFAS from the groundwater in drinking water wells that have been contaminated with the substances.

Currently, the most common method to filter drinking water for PFAS is via an active carbon filter, an ion-exchange filter, or by using a specially designed membrane. All of these possibilities filter PFAS from the water, but they do not destroy the PFAS. The filters are therefore all temporary, as they have to be sent for incineration to destroy the accumulated PFAS, or they end in landfills.

The project is called 'Machine Learning to Enhance PFAS Degradation in Flow Reactor', and it aims to design and develop an optimal and permanent solution for drinking water wells and treatment plants in Denmark that constantly captures and breaks down PFAS, while also monitoring itself.

"We need to be creative and think outside the box. I see many advantages in linking artificial intelligence with several different water treatment technologies, but integrating intelligence-based optimisation is no easy task. It requires strong synergy between machine learning and chemical engineering, but the perspectives are huge," says Associate Professor Zongsu Wei from the Department of Biological and Chemical Engineering at Aarhus University.

Autoneum’s sustainable, textile and lightweight Propylat technology reduces both interior and exterior noise of vehicles. Propylat was originally developed by Borgers Automotive, which was acquired by Autoneum in April 2023. The versatile technology is characterized by a flexible material composition of natural and synthetic fibers with a high recycled content and contributes to significant waste reduction thanks to its complete vertical integration. In addition, the fully recyclable technology variant Propylat PET is now part of the sustainability label Autoneum Pure.

The ongoing electrification of mobility as well as increasingly strict regulatory requirements for vehicle performance in terms of sustainability and acoustics are presenting new challenges to car manufacturers worldwide. With Propylat, Autoneum now offers another lightweight, fiber-based and versatile technology whose sound-insulating and -absorbing properties as well as high content of recycled materials help customers address these challenges. Propylat-based products not only contribute to reducing pass-by noise and improving driver comfort, but they are also up to 50 percent lighter than equivalent plastic alternatives; this results in a lower vehicle weight and, consequently, less fuel and energy consumption as well as lower CO2 emissions.

Autoneum's innovative Propylat technology consists of a mixture of recycled synthetic and natural fibers – the latter include cotton, jute, flax or hemp, for example – that are consolidated using thermoplastic binding fibers without adding any further chemical binders. Thanks to the flexible fiber composition and the variable density and thickness of the porous material, the properties of the respective Propylat variant, for example with regards to acoustic performance, can be tailored to individual customer requirements. This allows for a versatile application of the technology in a variety of interior and exterior components such as wheelhouse outer liners, trunk trim, underbody systems and carpets. For instance, Propylat-based wheelhouse outer liners significantly reduce rolling noise both inside and outside the vehicle while at the same time offering optimum protection against stone chipping and spray water.

In terms of sustainability, Propylat always contains a high proportion of recycled fibers – up to 100% in some variants – and can be manufactured with zero waste. Thanks to the full vertical integration of Propylat and Autoneum’s extensive expertise in recycling processes, the technology also contributes to a further significant reduction in production waste. Moreover, the Propylat PET technology variant, which consists of 100% PET, of which up to 70% are recycled fibers, is fully recyclable at the end of product life. For this reason, Propylat PET has been selected for Autoneum Pure – the Company’s sustainability label for technologies with excellent environmental performance throughout the product life cycle – where it will replace the current Mono-Liner technology going forward.

Propylat-based components are currently available in Europe, North America and China.

Freudenberg Performance Materials (Freudenberg) is extending its recently-introduced ECO range of sustainable nonwoven carpet backings: Lutradur ECO-R and Colback ECO-R backings contain high percentages of recycled raw materials. With its ECO portfolio Freudenberg supports carpet manufacturers in their transition towards an increasingly sustainable product offering.

The company launched its ECO range for sustainable primary backings earlier this year with the introduction of the ECO-RE resource-efficient backings that use less raw materials and support end product recyclability. To achieve this, Freudenberg R&D teams further developed the company’s proprietary yarn production technology allowing for extremely thin filaments.

ECO-R products
Freudenberg’s spunbond nonwoven primary and secondary carpet backings contribute to manufacturers’ easy and efficient production processes as well as to high-performance end products. The company is now extending its ECO range in Europe with Colback ECO-R and Lutradur ECO-R backings that contain a recycled content of between 51 and 90%. Replacing virgin raw materials with recycled polyester saves on natural resources and improves the carbon footprint of end products. The ECO-R backings are specifically suitable for carpet tiles, broadloom, dust control mats and automotive option mats.

Nylon 6, nylon 6,6, polypropylene, PET and calcium carbonate are available through the company’s proprietary carpet recycling process

Circular Polymers by Ascend, a market-leading recycler of post-consumer carpet, today the launch of Cerene™, a line of recycled polymers and materials made from the company’s proprietary carpet reclaiming technology. Cerene is available as polyamide 6 and 66, PET, polypropylene and calcium carbonate as a consistent,
sustainable feedstock for many applications, including molding and compounding.
Recycling experts from Circular Polymers will be showcasing Cerene at Compounding World Expo on June 14-15 at the Messe Essen in Germany.

Ascend Performance Materials, a fully integrated producer of durable high-performance materials and the majority owner of Circular Polymers by Ascend, is known for its innovations in nylon 6,6. Cerene will continue that legacy with offerings in nylon 6,6 while also bringing to market recycled polymers such as nylon 6, PET and PP.

“Customers around the globe are seeking consistent and reliable post-consumer recycled materials,” said Maria Field, business director of Circular Polymers by Ascend. “Cerene is mechanically recycled using a process that minimizes our carbon footprint and environmental impact.”

Circular Polymers by Ascend converts post-consumer carpet into fiber and pellets. The company uses a proprietary process in its California-based facilities to achieve high efficiency in recycling, successfully providing a new life for virtually every component of the carpet and backing. The company has redirected 85 million pounds of carpet from landfills into new goods since 2018.

Freudenberg Performance Materials (Freudenberg) announces the launch of sustainable carpet backing products for the flooring industry. Sustainable backings support customers in their transition towards producing more sustainable carpets. The range is introduced as Colback ECO and Lutradur ECO and is part of the Freudenberg portfolio of high-performance spunbond nonwoven technical textiles.

Reduced CO₂ footprint
Freudenberg follows a ‘less is more’ principle: the best raw materials are the materials that are not needed at all. For the ECO product range, Freudenberg R&D teams developed a solution to save raw materials in their carpet backings. Freudenberg redefined its proprietary yarn production technology allowing for extremely thin filaments with a diameter up to 30% smaller than the standard portfolio for carpet backings.  
The new thin yarn technology is one of Freudenberg’s sustainable initiatives benefitting the carpet industry. Other developments supporting sustainability include backings with a high recycled content and backings using alternative approaches to facilitate carpet recyclability. They will extend the ECO portfolio in the future.

ECO-CHECK-Label
The currently launched thin yarn ECO-backings have been awarded the ECO-CHECK label. Freudenberg introduced this label in early 2021 to identify particularly sustainable products within its portfolio.

Automotive carpets are typically multi-layered systems that can be challenging to recycle. By introducing a carpet made of 100% polyester, Autoneum now opens up new opportunities for vehicle manufacturers to meet their sustainability targets. The innovative carpet systems are fully recyclable, thus paving the way for an improved and more sustainable end-of-life recycling of electric vehicles. In addition, the high content of recycled PET as well as the zero waste and less energy-intensive production process further improve the carbon footprint of Autoneum’s new monomaterial needlepunch and tufted carpets.

Autoneum’s fully recyclable carpet systems ensure a closed material loop and are thus proof of the Company’s commitment to improving the sustainability performance of its products and manufacturing processes. The 100% polyester carpets build on the existing lightweight and particularly sustainable Autoneum Pure technologies: the carpet surface, for example, is made of Di-Light or Relive-1, while Hybrid-Acoustics PET is used for the decoupler. Thanks to Autoneum’s innovative alternative backcoating (ABC) process, which uses a thermoplastic adhesive instead of latex, the production of the new monomaterial needlepunch and tufted carpets also requires significantly less energy and no water at all.

Autoneum’s sustainable tufted carpet system made of 100% polyester is already in development for an electric model of a German vehicle manufacturer that will be available in Europe and Asia.

After two years of joint collaboration and research the Swiss Textile Recycling Project “Texcircle” comes to an end. Partners and stakeholders have worked on the vision of a textile cluster where materials flow in circular loops. The goal of the project was to develop high-quality yarns and products incorporating such a large amount of recycled textiles as possible. In the end, several product prototypes from carpets, socks, and curtains to pullovers, padding and accessories have been developed with at least 50 % recycled fiber up to 80 % recycled fibers and yarns.

Europe has a waste problem of 7.5 million waste of which only 30-35 % is collected and less than 1 % of the textile and clothing worldwide is recycled into textiles and clothing again. It is as well found that around 80 % of the impact of a textile product lies in the design.

Together with the design research expertise of the Lucerne University of Applied sciences and arts, the spinning expertise of Rieter and the sorting and collection expertise of Texaid, systems should be created where products of high quality can be produced of recycled fiber. On board were the expertise of further Cluster partners of Brands, Retailers, and the public sector to see how a joint Cluster and system coukld be established.

The Project Texcircle and cluster is led by the Lucerne University of Applied Sciences and Arts – Art  & Design, and in collaboration with Coop, Rieter, Jacob Rohner AG, Ruckstuhl AG, TEXAID as well as workfashion.com ag. Furthermore, Bundesamt für Zivildienst ZIVI, NIKIN AG, and Tiger Liz Textiles are supporting the project. The project is funded by Innosuisse.

Furthermore, collaboration partners from all over Europe contributed to the project to enable these prototypes and systems.

Through joint developments from the design, the collecting, sorting trials, tearing, and spinning trials until the actual production trials and product testing. The partners were able to recycle 2.5 Tons of pre-and post-consumer textile waste into product prototypes with a promising commercial interest. From socks, west, and pullovers to non-woven felts and accessories to carpets and curtains. Through our 2 years of collaboration, the teamcame across several hurdles in the textile recycling value chain which could be tackled. This was a proof of concept that a circular system is possible and the industry now has to enable this at full scale.

Ganesha Ecopet Private Limited, a subsidiary of Indian PET recycling pioneer Ganesha Ecosphere Ltd., has recently opened its new Warangal facility under the brand name Go Rewise where it produces rPET for filament yarns and fibres, as well as for food-grade packaging.  

The company has installed two Starlinger PET recycling lines in its facility in Warangal, Telangana state. Ganesha Ecopet plans to supply the produced rPET granulates under its newly introduced brand enterprise Go Rewise. Launched under the umbrella of one of India's rPET industry leaders, Go Rewise is committed to supplying highest quality rPET products that are produced in a resource-efficient process.
One Starlinger recycling line, a recoSTAR PET 165 H-VAC, processes washed PET bottle flakes for the Go Rewise polyester filament yarn applications and reaches an output of approx. 14,000 tons per year. With the second Starlinger recycling line, Ganesha is producing food-grade rPET resins.

Ganesha Ecosphere looks back on 30 years of experience in the PET recycling business and can be considered a role model regarding sustainable business activities. Founded in 1987, the company started out as a yarn processing facility. It was among the first companies in India to start reprocessing PET waste to manufacture recycled polyester staple fibre (RPSF) and recycled polyester spun yarns (RPSY) in 1994. By today, the group has established a large network of over 300 scrap vendors located across the country and operates four factories in India - two in Uttar Pradesh, one in Uttarakhand, and the recently opened one in Telangana. It also recently operationalised its first factory outside India in Nepal. With over 500 customers and exports to more than 18 countries, the company ranks among the largest rpet producers in India with 130,000 tonnes per year and currently recycles around 16 - 18 % of India's total PET waste.
