From the Sector

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.

Lenzing Group announced the collaboration with China’s internationally recognized denim mill, Advance Denim, to use matte TENCEL™ Lyocell fibers for their latest Denim Collection.

The TENCEL™ brand offers innovative and planet-friendly fiber solutions¹ that strive to enhance the adoption of responsible production² within the textile industry. Leveraging resource-saving, closed-loop production process³, TENCEL™ fibers are naturally soft and smooth to the touch and support a natural dry feeling through moisture control. The rollout of matte TENCEL™ Lyocell fibers in 2021 provided denim manufacturers with a solution that enabled them to enjoy the ample tactile and environmental benefits of TENCEL™ fibers, while also maintaining a matte finish on the end product.

“Matte TENCEL™ fibers are an extremely important innovation for the denim sector as they address the need for responsible denim made with less shine for a more vintage look. Many brands are currently looking for styles that meet this criterion while also providing softness and drapability for wide-leg jeans. Matte TENCEL™ fibers create the perfect mixture of performance and sustainability without sacrificing that true vintage indigo look,” said Amy Wang, General Manager of Advance Denim. “The matte denim in the ‘Denim Collection’, achieved by using matte TENCEL™ fibers, not only has exceptional softness to the touch, but its fiber properties also make the denim more like traditional cotton jeans after washing. This will enable the final garments to retain the intended retro style of the fabric.”

¹ TENCEL™ Lyocell and Modal fibers are certified with the EU Ecolabel for textile products (license no. AT/016/001) for environmental excellence.
² The responsible production of TENCEL™ Lyocell and Modal fibers uses at least 50% less water and emits at least 50% less CO2 compared to generic lyocell and modal fibers, according to Higg MSI, thereby saving precious resources for future generations. Results based on LCA standards (ISO 14040/44) and available via Higg MSI (Version 3.7).

The nominees:

The Straw Flexi-Dress: Design Meets Sustainability – DITF & VRETENA (DE)
The Flexi-Dress design was inspired by the natural golden colour and silky touch of HighPerCell® (HPC) filaments based on unbleached straw pulp. These cellulose filaments are produced using environmentally friendly spinning technology in a closed-loop production process. The design decisions focused on the emotional connection and attachment to the HPC material to create a local and circular fashion product. The Flexi-Dress is designed as a versatile knitted garment – from work to street – that can be worn as a dress, but can also be split into two pieces – used separately as a top and a straight skirt. The top can also be worn with the V-neck front or back. The HPC textile knit structure was considered important for comfort and emotional properties.

LENZING™ Cellulosic Fibres for Glacier Protection – Lenzing (AT)
Glaciers are now facing an unprecedented threat from global warming. Synthetic fibre-based geotextiles, while effective in slowing down glacier melt, create a new environmental challenge: microplastics contaminating glacial environments. The use of such materials contradicts the very purpose of glacier protection, as it exacerbates an already critical environmental problem. Recognizing this problem, the innovative use of cellulosic LENZING™ fibres presents a pioneering solution. The Institute of Ecology, at the University of Innsbruck, together with Lenzing and other partners made first trials in 2022 by covering small test fields with LENZING™ fibre-based geotextiles. The results were promising, confirming the effectiveness of this approach in slowing glacier melt without leaving behind microplastic.

The RENU Jacket – Advanced Recycling for Cellulosic Textiles – Pangaia (UK) & Evrnu (US)
PANGAIA LAB was born out of a dream to reduce barriers between people and the breakthrough innovations in material science. In 2023, PANGAIA LAB launched the RENU Jacket, a limited edition product made from 100% Nucycl® – a technology that recycles cellulosic textiles by breaking them down to their molecular building blocks, and reforming them into new fibres. This process produces a result that is 100% recycled and 100% recyclable when returned to the correct waste stream – maintaining the strength of the fibre so it doesn’t need to be blended with virgin material.
Through collaboration with Evrnu, the PANGAIA team created the world’s first 100% chemically recycled denim jacket, replacing a material traditionally made from 100% virgin cotton. By incorporating Nucycl® into this iconic fabric construction, dyed with natural indigo, the teams have demonstrated that it’s possible to replace ubiquitous materials with this innovation.

Textiles Made from Easy-to-dye Biocelsol – VTT Technical Research Centre of Finland (FI)
One third of the textile industry’s wastewater is generated in dyeing and one fifth in finishing. But the use of chemically modified Biocelsol fibres reduces waste water. The knitted fabric is made from viscose and Biocelsol fibres and is only dyed after knitting. This gives the Biocelsol fibres a darker shade, using the same amount of dye and no salt in dyeing process. In addition, an interesting visual effect can be achieved. Moreover, less dye is needed for the darker colour tone in the finished textile and the possibility to use the salt-free dyeing is more environmentally friendly.
These special properties of man-made cellulosic fibres will reassert the fibres as a replacement for the existing fossil-based fibres, thus filling the demand for more environmentally friendly dyeing-solutions in the textile industry. The functionalised Biocelsol fibres were made in Finnish Academy FinnCERES project and are produced by wet spinning technique from the cellulose dope containing low amounts of 3-allyloxy-2-hydroxypropyl substituents. The functionality formed is permanent and has been shown to significantly improve the dyeability of the fibres. In addition, the functionalisation of Biocelsol fibres reduces the cost of textile finishing and dyeing as well as the effluent load.

A New Generation of Bio-based and Resource-efficient Fibre – TreeToTextile (SE)
TreeToTextile has developed a unique, sustainable and resource efficient fibre that doesn't exist on the market today. It has a natural dry feel similar to cotton and a semi-dull sheen and high drape like viscose. It is based on cellulose and has the potential to complement or replace cotton, viscose and polyester as a single fibre or in blends, depending on the application.
TreeToTextile Technology™ has a low demand for chemicals, energy and water. According to a third party verified LCA, the TreeToTextile fibre has a climate impact of 0.6 kg CO2 eq/kilo fibre. The fibre is made from bio-based and traceable resources and is biodegradable.

B&B Italia unveiled a special edition Camaleonda, the iconic sofa system by Mario Bellini, adorned in a brand-new fabric designed by Stella McCartney – platforming her S-Wave monogram. Marking the second chapter of the partnership between the British conscious luxury pioneer and the Italian design house, the collaboration was launched at Art Basel Miami Beach on 6th December 2023 as part of an installation at B&B Italia Design Studio’s grand opening. The Camaleonda is crafted from nearly entirely sustainable materials, materialising both brands’ nature-positive visions.

The partnership between B&B Italia and Stella McCartney was born of Stella’s long-time personal passion for Bellini’s works and started in 2022 with the Le Bambole armchair. It evolves now with the new version of Camaleonda, the sofa system originally designed in 1970, which made its comeback 50 years later in 2020 - speaking a contemporary language between structural solutions and sustainable choices.

The brand-new Stella McCartney X B&B Italia Camaleonda introduces the latest printed fabric “S-Wave”, which is the result of a next-generation sustainability innovation introduced by the design company’s R&D team. The S-Wave upholstery, available in two different colours, is based on OceanSafe naNea yarn, which is verified to be biodegradable, Cradle to Cradle Certified® Gold and does not contain harmful substances. The material does not shed persistent microplastics into the environment, however, performs like conventional materials.

A collaboration between Deakin University researchers and Australia’s largest commercial linen supplier Simba Global is tackling a critical global issue, the spread of harmful microplastics through our laundry.

Clothing and textiles are estimated to generate up to 35 per cent of the microplastics found in the world’s oceans, making them one of the biggest contributors. But there is still a lot to be learnt about the characteristics of these microplastics and exactly how and why they are generated.

Researchers at the ARC Research Hub for Future Fibres in Deakin’s Institute for Frontier Materials (IFM) have teamed up with Simba Global, a global textile manufacturing and supply company, to better understand the extent and type of microplastics shed when their products are laundered. Simba Global wants to lead the charge to reduce the environmental impact of textiles.

Lead scientist IFM Associate Professor Maryam Naebe said working with an industry partner on the scale of Simba Global meant the research could have a huge real-world impact.

Simba Global is the major linen supplier to Australia’s hospitals, hotels and mining camps, resulting in 950,000 tonnes of textile products – including bedsheets, bath towels, scrubs and much more – going through the commercial laundering process each year. It also supplies international markets in New Zealand, Singapore and the US.

“As part of our research, we will investigate potential solutions including the pre-treatment of textiles to reduce the shedding of microplastics, or even increasing the size of the plastics that break down so they can be better captured and removed by filtration during the laundering process,” Associate Professor Naebe said.

“Microplastics are now ubiquitous in the environment, they’re in the air we breathe, the food we eat and the earth we walk on. The magnitude of the problem is bigger than previously thought.

“Of serious concern is the mounting evidence that microplastics are having a negative impact on human and animal health. There are not just physical, but chemical and biological impacts.”

Associate Professor Naebe’s team have taken the first steps in the project, analysing wastewater samples from commercial laundries with high-powered electron microscopes in their Geelong laboratory, part of the largest fibres and textiles research facility in Australia.

The team recently presented a new scientific paper at the Association of Universities for Textiles (AUTEX) Conference 2023, which started the important process of formally categorising these types of microplastics, as well as developing standard terminology and testing methods.

“Because our understanding of microplastics is still in its infancy, we needed to start right at the beginning,” Associate Professor Naebe said.

“We need to have a standard definition of what is a microplastic. Up to this point that has been lacking, which makes it difficult to compare and incorporate other studies in this area.

“We are now developing a systematic method for sampling and identifying microplastics in laundry wastewater. It has been tricky to measure the different sizes, but this is important information to have. For example, there are studies that suggest some sizes of microplastics are causing more issues in certain animals.

“The next step will be establishing an essential method to prevent the release of microplastics from textile laundering. This may involve a coating on the surface of the textile or better ways to collect the waste during the washing process.”

Simba Global Executive Chair Hiten Somaia said the company had a strong focus on sustainability, driven by the business’ purpose statement.

“We are proud to partner with Deakin University in what is the first significant research into textile microplastic pollution in Australia. What we are most excited about is sharing the results of this research with all other textile markets in Australia – including clothing – and putting an end to microplastic pollution from textiles.”

HeiQ’s biobased textile technologies are set to show how they can change the sleep environment for the better while meeting an increasing demand for sustainable solutions that are in tune with nature. HeiQ Skin Care, HeiQ Allergen* Tech, HeiQ Cool, and HeiQ Mint are going to be showcased at the Heimtextil show in Frankfurt beginning of January.

HeiQ presents a complete set of tailored textile technologies that is said to improve the sleeping environment: "Unlocking Better Sleep". Therefore, HeiQ introduces a range of innovative products designed to enhance the quality of a comfortable night’s rest through sustainable and biobased solutions.

According to a recent study by the School of Architecture, Victoria University of Wellington (New Zealand), “individuals spend more than 50% of their time at home in the bedroom”. Another research from the Fatigue Countermeasures Laboratory, NASA Ames Research Center (United States), concluded that “sleep is critical to health and daytime functioning. For individuals to achieve optimal sleep, they must have access to a sleep environment that allows them to achieve quality sleep.” These are strong indicators that we should treat sleep with the highest importance that it deserves.

The flagship products leading this positive change are the 100% biobased cosmetic technology HeiQ Skin Care, the plant-based deodorizer HeiQ Mint (botanical freshness), the dual action cooling solution HeiQ Cool, and HeiQ Allergen Tech that reduces exposure to inanimate allergens through active probiotics. These biobased innovations are set to redefine the sleep experience and contribute to overall well-being.

HeiQ Skin Care is the most recent addition to HeiQ’s portfolio - a synbiotic textile finish promoting a balanced microbiome for glowing skin. Unlike conventional products, HeiQ Skin Care utilizes pre- and probiotics integrated into a biobased matrix, offering long-lasting cosmetic benefits. It is particularly suited for products that are in direct and long contact with skin, such as pillowcases, duvet covers or bed sheets, acting as a cosmetic care session during sleep.

CARBIOS, a pioneer in the development and industrialization of biological technologies to reinvent the life cycle of plastic and textiles, has received an initial payment of €1.2 million from the French Agency for Ecological Transition (ADEME) for the OPTI-ZYME research project, carried out in partnership with INRAE2, INSA3 and CNRS4 via the TWB5 joint service and TBI6 research units, a project co-funded by the French State as part of France 2030 operated by ADEME. With CARBIOS' aim to optimize and continuously improve its unique enzymatic PET depolymerization technology, the 4-year7 OPTI-ZYME project aims to investigate the scientific and technical levers for improving the competitiveness of the process, optimizing the necessary investments and reducing its environmental footprint.

This collaborative R&D program focuses on the technical and economic optimization of process stages, while preserving the quality of the monomers obtained. These optimizations, new developments and the exploration of innovative solutions should enhance the technology's flexibility with regards to incoming waste. Raw materials could come from different sources that are currently rarely or not recycled, notably food trays and textiles, or a mix of incoming materials. It also aims to limit input and water consumption, as well as regenerate or reduce co-products and ultimate residual waste. Finally, it seeks to support enzyme optimization to maximize the process’ economic profitability and competitiveness.

The project therefore aims to achieve an overall improvement in performance, combining efficiency, quality and environmental sustainability, to benefit the Longlaville plant which is currently under construction, and future licensed plants.

In May 2023, CARBIOS, the project leader and coordinator, announced that it had been awarded a total of €11.4M in funding by the French State as part of France 2030, operated by ADEME, including €8.2M directly for CARBIOS (€3.2M in grants and €5M in repayable advances) and €3.2M for its academic partners INRAE, INSA and CNRS (via the TWB mixed service and TBI research units). This funding, which is made up of grants and repayable advances, will be paid out in several instalments over the course of the project, including an initial instalment of 15%, equivalent to €1.2 million, received by CARBIOS on 5 December 2023. The first Monitoring Committee with ADEME for the first key stage of the project will be held in February 2024 to validate the granting of the second instalment of funding.

This project 2282D0513-A is funded by the French State as part of France 2030 operated by ADEME.
