From the Sector

Der Statusbericht der deutschen Kreislaufwirtschaft 2024 beleuchtet zum dritten Mal nach 2018 und 2020 die Situation der deutschen Kreislaufwirtschaft. Seit der ersten Veröffentlichung im Mai des Jahres 2018 sind fast sechs Jahre vergangen. In diesem Zeitraum haben in Deutschland zwei Ereignisse für eine veränderte Sichtweise auf die Branche geführt: Zunächst die Corona-Krise, die nicht nur die Leistungs- und Anpassungsfähigkeit der Branche, sondern auch ihre Systemrelevanz für die Funktionsfähigkeit des gesellschaftlichen und wirtschaftlichen Lebens unter Beweis gestellt hat. In diesem Zusammenhang ist seit Anfang des Jahres 2020 auch das Ansehen der Abfallentsorgung und vor allem der beteiligten Mitarbeiterinnen und Mitarbeiter in der Bevölkerung deutlich gestiegen.

Der Angriffskrieg auf die Ukraine hat vor Augen geführt, wie stark Deutschland von Energie- und Rohstoffimporten abhängig ist und wie schnell Störungen in den Lieferketten zu Problemen bei der Versorgung mit wichtigen Gütern führen können. Die Abfallwirtschaft kann sowohl durch die Kreislaufführung von Rohstoffen als auch durch die energetische Verwertung wichtige Beiträge zur Reduzierung dieser Abhängigkeiten leisten.

Die Kernthesen des Statusberichtes 2024

• Das gesamte Abfallaufkommen in Deutschland bleibt seit vielen Jahren stabil bei rund 400 Millionen Tonnen, die Abfallmengen aus privaten Haushalten steigen sowohl absolut als auch pro Kopf weiter leicht an
• Die Kreislaufwirtschaft wächst weiter: Mehr Recycling, mehr Beschäftigung und ein Umsatzsprung durch höhere Rohstoffpreise.
• Kreislaufwirtschaft international: Wachsende Märkte für Technik und Güter bei zunehmendem Wettbewerbsdruck für die deutschen Unternehmen
• Kreislaufwirtschaft vernetzt: Bedeutende Beiträge zum Klimaschutz, zur Rohstoffversorgung und zur Energiewende.
• Die Wertschätzung der Branche und ihrer Beschäftigung nimmt zu, gleiches gilt allerdings nicht für die Akzeptanz der für die stoffliche und energetische Verwertung notwendigen Anlagen.
• Kreislaufwirtschaft digital und innovativ: Die Digitalisierung unterstützt Sammlung und Transport, innovative Verfahren verbessern die Recyclingergebnisse, Startups mit neuen Ideen
• Produzenten und Recycler rücken immer enger zusammen, gleichwohl sind für den Wiedereinsatz von Recyclingrohstoffen die Absatzmärkte sicherzustellen
• Brüssel gibt mittlerweile in vielen Feldern der Kreislaufwirtschaft die Zielrichtung und die Geschwindigkeit vor. Das Ziel: Die Transformation von einer linearen Wirtschaft zu einer Circular Economy
• Für den Transformationsprozess zur Circular Economy ist eine funktionierende Kreislaufwirtschaft die wichtigste Basis, gleiches gilt für den Green Deal

At the end of last year, KARL MAYER launched the TM 4 EL – a new, highly flexible machine for the mid-range segment in the four-bar tricot machine sector. The machine produces fabrics for upholstery, automotive interiors and outerwear, as well as sportswear items and home textiles.

The new TM 4 EL is offered in gauges E 28 and E 32. The available working widths are 210” and 280”, with a working width extension also available. Further width varieties are also planned. Equipment highlights include an integrated Laser Stop to detect yarn breakages early, and functional LED lighting, which illuminates the warp knitting area for easy handling and signals unplanned machine stops using the corresponding colour. The machine can be networked with KM.ON’s secure cloud via the k.ey device to utilise the KARL MAYER GROUP’s digital solutions. This includes, for example, the web-based lapping editor CORE LITE.

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.

Disney unveiled the HoloTile floor, created by Disney Research Fellow and longtime member of Walt Disney Imagineering Research & Development Lanny Smoot.

The HoloTile floor is a multi-person, omni-directional, modular, expandable, treadmill floor. It allows any number of people to have a shared virtual reality (VR) experience, walk an unlimited distance in any direction, and never collide or walk off its surface.

The HoloTile floor can also be an insert in a theatrical stage, allowing performers to move and dance in new ways, or stage props and structures to move around or appear to set themselves up.

The new technology was revealed (see here), as Lanny Smoot is being inducted into the National Inventors Hall of Fame. He is the first Disney Imagineer to receive this recognition.

Smoot is also credited with giving Madame Leota her ability to “float” in the Séance Room at the Haunted Mansion at Disneyland Park; crafting the state-of-the-art extendable lightsaber used by Disney Live Entertainment; inventing the Magic Playfloor interactive game experience on the Disney Cruise Line; producing the immersive Fortress Explorations adventure at Tokyo DisneySea; and designing the virtual and interactive koi ponds at the Crystal Lotus Restaurant at Hong Kong Disneyland Hotel.

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.

Additionally, it is verified in the Product Environmental Footprint.

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.

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.

On 10 January, Re:NewCell AB ("Renewcell") announced that they are planning to start negotiations with the relevant trade unions regarding restructuring of the organization to improve efficiency while maintaining focus on sales.

As part of the restructuring, the local authorities (Arbetsförmedlingen) will also be notified. The planned restructuring will lead to a decrease in workforce of approximately 25%, just over 30 persons, and will also result in annual savings – reduction of personnel cost and other operating costs – of approximately 35 SEKm in total per annum when finalized.

Magnus Håkansson, acting CEO, says: “This kind of decision is never easy to make and would not be planned for unless it was absolutely necessary for our long-term success. The planned restructuring of the organization means that Renewcell will maintain conditions for efficient production while continuing to focus on the development of sales to fiber producers as well as focusing on marketing activities to the major clothing brands that determine the final demand in the supply chain.”

The Dutch company Knitwear Lab helps visions become reality. The creative think tank offers capacities in the areas of R&D, design, knitwear development and production of prototypes and small quantities and has thus implemented a wide range of projects in recent years. The objects range from medical products and high-tech sportswear to smart textiles with integrated sensors. Sustainability activities are also part of the repertoire, such as the production of yarns from recycled waste.

Knitwear Lab operates at two locations for its diverse tasks: Almere in the Netherlandsis available for development work. In Istanbul, there is a branch for production. Both Knitwear Lab sites each have five STOLL flat knitting machines, including models from the modern ADF range. Prototypes are produced in Almere and there is small-scale production. The production plant in Istanbul specializes in the manufacture of high-quality knitwear in small quantities. STOLL is also involved in the creative processes. For the industrial development of knitwear, Knitwear Lab offers Virtual Knitting, a revolutionary method that combines virtual and physical elements of pattern development and knitwear production to reduce waste and pre-production steps. Customers can use Virtual Knitting to create realistic, producible collections, simplify their design iteration processes and take advantage of the wide range of real-life colorways. The basis for this is comprehensive knitwear expertise, the latest 3D software and the CREATE PLUS patterning software, which was developed by STOLL together with KM.ON.

"The 3D visualization of CREATE simplifies communication with the customer considerably. We use this function every day," says Annika Klaas, Senior Knitwear Programmer. She personally appreciates the uncomplicated grading and exchange of stitch dimensions and the much faster and more efficient work with Dimensioned Shapes that this makes possible. This helps her in her day-to-day work. "We often have requests to realize the same product in different yarns, which now works much faster," says the programmer. Further simplifications would include minor optimizations in terms of the efficiency and user-friendliness of programming and additional import and export options for shapes. Discussions on implementation are already underway.
