From the Sector

The German Institutes of Textile and Fiber Research Denkendorf (DITF) have modernized and expanded their melt spinning pilot plant with support from the State of Baden-Württemberg. The new facility enables research into new spinning processes, fiber functionalization and sustainable fibers made from biodegradable and bio-based polymers.

In the field of melt spinning, the DITF are working on several pioneering research areas, for example the development of various fibers for medical implants or fibers made from polylactide, a sustainable bio-based polyester. Other focal points include the development of flame-retardant polyamides and their processing into fibers for carpet and automotive applications as well as the development of carbon fibers from melt-spun precursors. The development of a bio-based alternative to petroleum-based polyethylene terephthalate (PET) fibers into polyethylene furanoate (PEF) fibers is also new. Bicomponent spinning technology, in which the fibers can be produced from two different components, plays a particularly important role, too.

Since polyamide (PA) and many other polymers were developed more than 85 years ago, various melt-spun fibers have revolutionized the textile world. In the field of technical textiles, they can have on a variety of functions: depending on their exact composition, they can for example be electrically conductive or luminescent. They can also show antimicrobial properties and be flame-retardant. They are suitable for lightweight construction, for medical applications or for insulating buildings.

In order to protect the environment and resources, the use of bio-based fibers will be increased in the future with a special focus on easy-to-recycle fibers. To this end, the DITF are conducting research into sustainable polyamides, polyesters and polyolefins as well as many other polymers. Many 'classic', that is, petroleum-based polymers cannot or only insufficiently be broken down into their components or recycled directly after use. An important goal of new research work is therefore to further establish systematic recycling methods to produce fibers of the highest possible quality.

For these forward-looking tasks, a bicomponent spinning plant from Oerlikon Neumag was set up and commissioned on an industrial scale at the DITF in January. The BCF process (bulk continuous filaments) allows special bundling, bulking and processing of the (multifilament) fibers. This process enables the large-scale synthesis of carpet yarns as well as staple fiber production, a unique feature in a public research institute. The system is supplemented by a so-called spinline rheometer. This allows a range of measurement-specific chemical and physical data to be recorded online and inline, which will contribute to a better understanding of fiber formation. In addition, a new compounder will be used for the development of functionalized polymers and for the energy-saving thermomechanical recycling of textile waste.

Re:NewCell AB announced that the Stockholm District Court has decided to approve the previously communicated bankruptcy application and has declared the company bankrupt.

The appointed bankruptcy trustee is lawyer Lars-Henrik Andersson at Cirio Advokatbyrå.

February,25 the Board of Directors had decided to file for bankruptcy of Re:NewCell AB at the Stockholm District Court. The reason for the decision to file for bankruptcy was that Re:NewCell has not been able to secure sufficient financing to complete the strategic review, announced on 20 November 2023, with satisfactory result.

As part of the strategic review, Re:NewCell has had well advanced negotiations with its two largest shareholders, H&M and Girindus, its existing lenders BNP Paribas, European Investment Bank, Finnvera (as partial guarantor), Nordea, AB Svensk Exportkredit and potential new investors as well as other stakeholders regarding long-term financing solutions. These discussions have not resulted in a solution which would provide Re:NewCell with the necessary liquidity and capital to ensure its operations going forward.

"I regret to inform that we have been forced to take this decision to file for bankruptcy. As we have a strong belief in the company’s long-term potential, we have together with our advisors spent very substantial time and efforts into trying to secure the necessary liquidity, capital and ownership structure for the company to secure its future. As part of the negotiations, we have had intense dialogues with both current main owners, new investors and our banks, as well as other stakeholders. However, these discussions have not been successful. This is a sad day for the environment, our employees, our shareholders, and our other stakeholders, and it is a testament to the lack of leadership and necessary pace of change in the fashion industry” says Chairman of the Board of Directors, Michael Berg.

Haelixa, the trailblazer of physical traceability solutions, has partnered with Trudel Silk, a market leader for sustainable organic and recycled silk products. This collaboration brings traceability and transparency to silk production.

Silk is one of the finest and smoothest fabrics; the better the quality of the silk, the more luxurious it feels to the touch. To create the best quality silk, the conditions for mulberry cultivation must be up to the highest standards. A healthy micro-ecosystem in the fields translates to top-grade silk cocoon quality. At Trudel, this is the environment they have created for the vertical integration of their business. Trudel aims to succeed at every stage of the process, which can only be accomplished through the active involvement and visible cooperation of all market players. These players include farmers, reeling mills, twisting/spinning mills, weaving mills, dyeing and printing mills, and brands. They are involved in every step, from the cultivation of mulberry trees to the production of silk fabrics.

Haelixa and Trudel have collaborated to improve silk’s robust and consistent traceability. As the demand for validation of the silk value chain increases, they have partnered with groups from Italy and Asia to develop a unique solution that uses DNA markers to trace the entire supply chain of silk production. This innovative approach ensures each silk product’s ethical sourcing.

The silk fibers used in their spun silk yarns are marked with a specific DNA per farm set selected by Trudel. Throughout the supply chain, samples of yarn, fabrics, and finished products undergo testing to verify the presence of original silk fibers. Based on the reporting, the brand can trace the finished accessories or garments to Trudel.

“From Earth to Earth”: The new plan defines goals and concrete actions in Environmental, Social and Governance (ESG) areas to foster value creation for all stakeholders and put new sustainability regulatory requirements at the centre of attention.

A project, designed to enhance RadiciGroup's transparency and commitment to develop a responsible business along its entire value chain from an economic, social and environmental perspective and focus on the ever more widespread and stringent sustainability regulatory requirements. These are the features and goals of the Sustainability Plan presented by the Group and called "From Earth to Earth", precisely to emphasize the intent to focus on the Earth and future generations.

In the context of a complex and constantly changing scenario, the Group has therefore decided to capitalize on the goals achieved and look beyond them with a plan defining the medium-term targets and the actions to be taken to fulfil them and covering all areas considered to be "material”, i.e., relevant from the point of view of ESG and financial risks, opportunities and impacts. Indeed, the ultimate goal of "From Earth to Earth" is to support business continuity and the growth of the company and all its stakeholders.

The project was the result of a multi-year collaboration with Deloitte, which contributed an external and objective viewpoint on the definition of the material targets and themes. However, it was not an armchair exercise, but the result of an extensive listening process involving internal and external stakeholders, all of whom were sustainability experts who helped define a shortlist of strategic themes for both the Group and its main stakeholders. These issues were then analysed in detail using working tables on the different themes to identify the objectives in Environmental, Social and Governance areas and the related concrete actions needed to achieve them, in line with the European decarbonization and energy transition policies and the
United Nations Sustainable Development Goals, a global blueprint for sustainable growth.

In particular, RadiciGroup’s environmental goals include: a 20% increase and differentiation in renewable source electricity consumption, an 80% reduction in total direct greenhouse gas emissions by 2030 compared to 2011, attention to water consumption to limit the impact on local communities and biodiversity, the extension of Life Cycle Assessment (LCA) methodology to measure the environmental impact of 70% of the products (in terms of weight) manufactured by the entire Group, collaboration among the various actors in the supply chain from an ecodesign perspective and the search for increasingly more sustainable and circular packaging solutions.

A lot of waste is generated in the trade fair and event industry. It makes sense to have furniture that can quickly be dismantled and stored to save space - or simply disposed of and recycled. Paper is the ideal raw material here: locally available and renewable. It also has an established recycling process. The German Institutes of Textile and Fiber Research (DITF) and their project partners have jointly developed a recycling-friendly modular system for trade fair furniture. The "PapierEvents" project was funded by the German Federal Environmental Foundation (DBU).

Once the paper has been brought into yarn form, it can be processed into a wide variety of basic elements using the structure winding process, creating a completely new design language.

The unusual look is created in the structure winding process. In this technology developed at the DITF, the yarn is deposited precisely on a rotating mandrel. This enables high process speeds and a high degree of automation. After the winding process, the individual yarns are fixed, creating a self-supporting component. A starch-based adhesive, which is also made from renewable and degradable raw materials, was used in the project for the fixation.

The recyclability of all the basic elements developed in the project was investigated and confirmed. For this purpose the research colleagues at the project partner from the Department of Paper Production and Mechanical Process Engineering at TU Darmstadt (PMV) used the CEPI method, a new standard test procedure from the Confederation of European Paper Industries.

Sensor and lighting functions were also implemented in a recycling-friendly manner. The paper sensor yarns are integrated into the components and detect contact.

Also, a modular system for trade fair and event furniture was developed. The furniture is lightweight and modular. For example, the total weight of the counter shown is well under ten kilograms and individual parts can easily be shipped in standard packages. All parts can be used several times, making them suitable for campaigns lasting several weeks.

A counter, a customer stopper in DIN A1 format and a pyramid-shaped stand were used as demonstrators. The research work of the DITF (textile technology) and PMV (paper processing) was supplemented by other partners: GarnTec GmbH developed the paper yarns used, the industrial designers from quintessence design provided important suggestions for the visual and functional design of the elements and connectors and the event agency Rödig GmbH evaluated the ideas and concepts in terms of usability in practical use.

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.

The report details sustainability efforts at its Boennigheim headquarters and targets for 2024. Hohenstein has replaced previous environmental guidelines with strategic development in accordance with Environmental, Social and Corporate Governance (ESG) and adopted a sustainability roadmap for the future.

Hohenstein has been implementing environmental and social measures for decades. As the first neutral assessment of these measures in 2019, Hohenstein participated in the ECOfit programme in Baden-Württemberg, Germany. A regular external assessment is to be introduced in 2024.

• Environmental: Overall, energy consumption was actively reduced, and renewable energy use promoted. Hohenstein also collected rail and air travel data to be used in CO2 accounting in 2024.
• Social: Hohenstein actively involved its employees in sustainability activities based on a survey and internal education. In future, Hohenstein will improve the ratio of female managers and implement a training campaign on the company values for employees.
• Governance: Hohenstein management has prioritized good communication through regular colloquia for employees and access to human resources consultation. They intend to intensify the dialogue with employees through further events.
