From the Sector

More than 82 companies, businesses and social organizations – including AkzoNobel – are involved in a major Dutch research program focused on developing new technologies that will help solve some of today’s societal challenges.
 
Seven broad consortia have been established as part of the government-funded “Perspectief” program, with AkzoNobel set to play a leading role in the SusInkCoat project, which will explore how to make inks and coatings more sustainable.

The company will work together with private partners and other societal stakeholders to develop new materials, processes and applications to improve the durability, functionality and recyclability of coatings, thin films and inks. The program, which will run for the next five years, is backed by the Ministry of Economic Affairs and Climate Policy and the Dutch Research Council (NWO).

“Our discussions about collaborating with our SusInkCoat partners have been very positive,” says AkzoNobel’s R&D Director of Scientific Academic Programs, André van Linden, who is also the co-lead of SusInkCoat. “We’re all facing the same societal challenges – how to become more circular – and we’re looking for the same solutions in different application areas. But we’ve never done that together for this specific research topic, so we need an ecosystem to help us solve these challenges.
 
Van Linden adds that the program – one of many R&D projects the company is involved with – will also support AkzoNobel’s ambition to achieve 50% less carbon emissions in its own operations – and across the value chain – by 2030.
 
 “We want to make the recyclability of materials - such as furniture, building materials and steel constructions - easier by introducing functionalities like self-healing, higher durability and triggered release,” he continues. “The more you can leave the materials in their original state, the more sustainably you can operate.”

AkzoNobel will be collaborating with Canon, Evonik, GFB, PTG and RUG Ventures, who together possess extensive knowledge of market demands, supply chains and production processes. All the SusInkCoat partners will also work with academic researchers at several Dutch universities in an effort to identify promising developments that can be commercialized, used for education purposes or for outreach to the public.

Research being conducted by the other six consortia includes investigating methods to make tastier plant-based food; flat optics for more sustainable hi-tech equipment; and cheaper and more accessible medical imaging technology.

Solvay is partnering with transportation providers KIITOSIMEON and ADAMS LOGISTICS to reduce the carbon footprint of its facility in Voikkaa, Finland. Known for its hydrogen peroxide technology, the site has a yearly capacity of 85 kilotons, making it the largest hydrogen peroxide unit in the country and one of the largest in Europe. However, the transportation of its products results in more than 850 tons of CO2 emissions annually, attributed to the several thousands deliveries conducted each year.

While the Voikkaa site has been operating on 100% wind-generated electricity since 2023, the journey towards decarbonization takes another step forward as it transitions transportation fuel from diesel to biofuel in the first quarter of 2024. This shift will result in a significant annual reduction of over 700 tons of CO2 emissions, representing more than 8O% reduction in the site's transportation carbon footprint.

As part of its commitment to carbon neutrality by 2050, Solvay has outlined a sustainability roadmap with around 40 energy transition projects. These projects focus on eliminating coal usage, emphasizing renewable energy sources, prioritizing energy efficiency, and driving process innovation. Solvay has further committed to reduce its emissions* along the value chain by 20% by 2030.

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.

The Lenzing Group has once again been recognized for its sustainability performance and its active contribution to transforming the industry towards a circular economy. The rating agency MSCI awarded Lenzing an “AA” rating for the third time in a row, placing Lenzing among the top eight percent of rated companies in its peer group. In addition, Lenzing participated for the first time in the SAC Higgs FEM verification to assess the environmental impact of product manufacturing at its sites and achieved positive results.

According to the rating agency MSCI, Lenzing continues to lead the way among global companies in terms of governance structures. In addition, MSCI highlights Lenzing’s leadership in implementing initiatives to mitigate the risk of environmental liabilities associated with the release of toxic pollutants and highlights its water stewardship program, which includes a water risk assessment. The confirmation of the “AA” rating from MSCI ESG enables Lenzing to further reduce its interest expense. In November 2019, Lenzing placed a bonded loan in the amount of around EUR 500 mn, which is linked to the company's sustainability performance. In line with its commitment under the bonded loan, the company will donate the entire interest expense it saves thanks to the “AA” rating to a social-ecological project.

By November 2023, all Lenzing sites, with the exception of the sites in Brazil and Thailand, which are however scheduled for 2024, have completed the first external verification of the module with excellent results. With almost 20,000 participating companies from different sectors of industry, which achieved less than 50 percent in total average in 2023, Lenzing sites achieved verified scores of more than 70 percent to 95 percent.

Growth, digitalisation and re-commerce – the forthcoming INNATEX (the international trade fair for sustainable textiles) is devoted to highly topical themes. From 20 to 22 January 2024 at the Messecenter Hofheim Rhein-Main near Frankfurt, over 200 exhibitors will be meeting up with retailers, experts and journalists. The motto for the winter trade fair is GROW, representing the call for sustainable, social and commercial growth that will not be possible without the green fashion movement.

Optimistic expectations despite the challenges
According to Alexander Hitzel, INNATEX Project Manager, and the organisers, MUVEO GmbH, various new trends are opening up that might, if exploited strategically, unlock new business areas. These range from ‘quiet luxury’, travel, internationalism and focused storytelling to services for specific target groups. On the Monday, members of the expert panel will be discussing re-commerce with the Hessen Retail Federation in the Community Lounge.

From storytelling to digital tools – the INNATEX themes
“Second-hand is in fashion,” says Julia Frings of IFH Köln. “Sales of used and recycled products have been on an upward trend for some years now and with the rising importance of sustainability, their relevance will continue to grow. There is great potential in this area for the trade to reach new target groups and expand the range on offer. To be successful, though, it is essential to have a concept tailored to the needs of consumers.”

Alongside Julia Frings of IFH Köln, other Federation panellists will include Steffen Riegel of Hessnatur. The first Lounge Talk at the start of INNATEX will deal with Strategies for Sensible Growth, borrowing from the motto for the fair. This topic will be followed by Fair Wages in the Global South, Storytelling as a Strategy, and Digital Trends.

Brand portfolio and partners of INNATEX
The collaboration with the Hessen Retail Federation, like that with Fashion Changers and Greenstyle Munich, has already proved its worth at previous fairs, as a way of adding variety to a well balanced fair programme. The new collaborative partners include AMD Academy of Fashion and Design (AMD) in Wiesbaden, the Fashion Campus 2030 Initiative and the Enterprise Europe Network (EEN, a network promoting internationalisation among smaller and medium-sized businesses).

The brand portfolio includes fashion for all generations, tastes and occasions. Labels exhibiting for the first time include businesses such as Fuza Wool from Denmark with its high quality traditional knitwear, and the hemp-based accessories of 8000Kicks from Portugal. The DESIGN DISCOVERIES comprise Anfisa Roumelidi, C/OVER and Consci.

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.”

The kick-off meeting for the "Trends and Design Factors for Hydrogen Pressure Vessels" project, recently held at AZL Aachen GmbH, was a successful event, bringing together more than 37 experts in the field of composite technologies. This event laid a solid foundation for the Joint Partner Project, which currently comprises a consortium of 20 renowned companies from across the composite pressure vessel value chain: Ascend Performance Materials, C evotec GmbH, Chongqing Polycomp International Corp. (CPIC), Conbility GmbH, Elkamet Kunststofftechnik GmbH, F.A. Kümpers GmbH & Co. KG, f loteks plastik sanayi ticaret a.s., Formosa Plastics Corporation, Heraeus Noblelight GmbH, Huntsman Advanced Materials, Kaneka Belgium NV, Laserline GmbH, Mitsui Chemicals Europe GmbH, Plastik Omnium, Rassini Europe GmbH, Robert Bosch GmbH, Swancor Holding Co. Ltd. Ltd., TECNALIA, Toyota Motor Europe NV/SA, Tünkers do Brasil Ltda.

The project follows AZL´s well proven approach of a Joint Partner Project, aiming to provide technology and market insights as well as benchmarking of different material and production setups in combination with connecting experts along the value chain.

The kick-off meeting not only served as a platform to foster new contacts and get informed about the expertise and interests of the consortium members in the field of hydrogen pressure vessels, but also laid the groundwork for steering the focus of the upc oming project's ambitious phases. As a basis for the interactive discussion session, AZL outlined the background, motivation and detailed work plan. The central issues of the dialogue were the primary objectives, the most pressing challenges, the contribut ion to competitiveness, and
the priorities that would best meet the expectations of the project partners.

Discussions covered regulatory issues, the evolving value chain and the supply and properties of key materials such as carbon and glass fibres and resins. The consortium defined investigations into different manufacturing technologies, assessing their matu rity and potential benefits. Design layouts, including liners, boss designs and winding patterns, were thoroughly considered, taking into account their implications for mobile and stationary storage. The group is also interested in cost effective testing m ethods and certification processes, as well as the prospects for recycling into continuous fibres and the use of sustainable materials. Insight was requested into future demand for hydrogen tanks, OEM needs and strategies, and technological developments to produce more economical tanks.

The meeting highlighted the importance of CAE designs for fibre patterns, software suitability and the application dependent use of thermoset and thermoplastic designs.

The first report meeting will also set the stage of the next project phase, which will be the creation of reference designs by AZL's engineering team. These designs will cover a range of pressure vessel configurations using a variety of materials and production concepts. The aim is to develop models that not only re flect current technological capabilities, but also provide deep insight into the cost analysis of different production technologies, their CO₂ footprint, recycling aspects and scalability.

AZL's project remains open to additional participants. Companies interested in joining this initiative are invited to contact Philipp Fröhlig.

In cooperation with testing provider Hohenstein, Under Armour is launching a new fiber-shed test kit. It will help textile companies along the supply chain to develop lower shed materials during product development. The companies carry out the test themselves in-house using the test kit or can commission Hohenstein as a testing service provider.

The kit is a one-off purchase, after which users can buy additional materials from project partner James Heal. By using the new kit, Under Armour can reliably assess the quality and shed rate of the materials from suppliers.

For Hohenstein customers, the test kit is a useful addition to their microplastics tests. It is a quick and relatively inexpensive preliminary test that ensures better early-stage results for the end product.

During the production, wear and laundering of synthetic and natural fabrics, fibre shedding occurs in varying degrees. Hohenstein and Under Armour expect that their test method will help the industry better understand and reduce its contribution to the microfibre problem.

“Until now, integrating fiber-shed testing into industry research and development activities has required a significant time and cost investment,” said Kyle Blakely, Senior Vice President of Innovation for Under Armour. “At Under Armour, we believe intervening early to mitigate shedding is critical, which is why our test method is designed to specifically address these time and cost barriers.”

Carbios was one of eight beneficiaries selected to present the progress of its industrial project in the presence of the President of the French Republic on the occasion of the two-
year anniversary of the launch of the France 2030 investment plan. Carbios is receiving €42.5 million in public funding (€30 million from the State as part of France 2030 and €12.5 million from the Grand-Est Region) for the construction of the plant for the enzymatic depolymerization of PET. Carbios is an emblematic example of the France 2030 initiative to support innovative projects that contribute to reindustrialization through innovation in strategic sectors, such as recycling. This plant, located in Longlaville in the Grand-Est Region, will be Carbios' first industrial site. Construction has just begun.

Carbios' technology enables PET circularity and provides an alternative raw material to virgin fossil-based monomers, allowing PET producers, waste management companies, public entities, and brands to have an efficient solution to meet regulatory requirements and fulfill their own sustainability commitments. The plant will have a processing capacity of 50,000 tons of post-consumer PET waste per year (equivalent to 2 billion colored PET bottles, 2.5 billion PET trays, or 300 million T-shirts) and will address waste with little or no value such as colored PET bottles, food trays, and textiles. The plant will create 150 direct and indirect jobs in the region. In October 2023, Carbios obtained the building permit in 10 months (the average duration in France is 17 months) and the site operating permit, allowing construction to begin. The plant is currently under construction in Longlaville in the Grand-Est Region.

Partnership between Nouvelles Fibres Textiles, Pellenc ST and ANDRITZ promotes circular economy for textiles.

France’s first industrial plant for automated sorting and recycling of textile waste was officially inaugurated at Nouvelles Fibres Textiles, Amplepuis, on November 30, 2023. The plant is the result of an ambitious partnership between textile recycling company Nouvelles Fibres Textiles, waste sorting specialist Pellenc ST and international technology group ANDRITZ, a specialist in textile recycling machinery and processes.

Capable of automatically sorting garments by composition and color, the new line meets the needs of both post-consumer and post-industrial waste markets. The line also removes hard parts such as buttons and zippers to prepare the material for further processing in an ANDRITZ tearing machine.

The automated textile sorting line at Nouvelles Fibres Textiles is dedicated to industrial-scale production, customer trials and projects, and the R&D activities of the partners. It will process textile waste to produce recycled fibers for the spinning, nonwovens, and composites industries.

Automated sorting was the last missing link needed to develop a complete ecosystem in France, where the fashion industry, social and solidarity economy actors, waste management companies, and textile producers from different sectors are working together towards a textile circular economy.

The EU's strategy for sustainable and circular textiles aims to ensure that by 2030 textile products are made to a great extent of recycled fibers and incineration and landfilling of textiles are minimized.
