From the Sector

The ZEBRA (Zero wastE Blade ReseArch) project marks a significant leap forward in the recycling and circular economy for wind turbine blades. This collaborative effort demonstrates a breakthrough in the complete recycling of thermoplastic blades achieving significant environmental and economic benefits.

The ZEBRA project is a unique partnership led by the French Institute for Technological Research, IRT Jules Verne. Joining forces are industry leaders Arkema (resin supplier), Owens Corning (glass fiber supplier), LM Wind Power (blade manufacturer), SUEZ (dismantling and waste processing), CANOE R&D center (recycling technology), and ENGIE (life cycle analysis).

Each company played a crucial role in the development of the closed-loop recycling process:

• Arkema developed and validated the generation of recycled Elium® monomer through thermolysis, and, together with its subsidiary Bostik, an innovative adhesive for the blade assembly that is recycled together with Elium® paving the way for industrial-scale implementation.
• Owens Corning successfully recovered glass fiber at pilot scale, enabling its reintroduction into the production process for their Sustaina® product line.
• LM Wind Power manufactured two wind turbine blades with Arkema’s Elium® resin and Owens Corning’s Ultrablade® fabrics; one blade including a large structural element made with recycled Elium® resin.
• SUEZ provided cutting and grinding expertise for processing the blades.
• CANOE R&D center optimized recycling for production and carbon blade waste, additionally developing methods for repurposing waste streams through mechanical recycling.
• ENGIE conducted a comprehensive life cycle analysis demonstrating the environmental benefits of closed-loop ZEBRA blades and validated their economic viability.

A Sustainable Future for Wind Energy
The ZEBRA project successfully recycled Elium® resin and Ultrablade® fabrics from wind turbine blades and manufacturing waste, reformulating them back into usable materials. This closed-loop process addresses the growing challenge of end-of-life blade management within the wind energy industry.

• Recycled Elium® Monomer: Arkema achieved a yield of over 75% in the thermolysis process, paving the way for industrial-scale production of recycled resin.
• Recovered Glass Fiber: Owens Corning successfully retrieved glass fiber for remelting and reintegration into their Sustaina® product line.
• Life Cycle and Cost Analysis: ENGIE's study confirmed the significant environmental benefits and economic viability of ZEBRA blades when assuming a closed-loop recycling system from production to end-of-life.

ZEBRA blade using Elium® thermoplastic resin, Bostik’s highly compatible adhesive and Ultrablade® fabrics is bringing the best closed-loop recycling solution compared to traditional thermoset system. The operating cost and investments for recycling facility are significantly lowered. The CO2 emission linked to the recycling operations is reduced as well. All those results are making the closed-loop recycling solution of ZEBRA blades a viable option both on economic and environmental standpoints.

By demonstrating the feasibility of full wind turbine blade recycling, the ZEBRA project paves the way for a more sustainable future in the wind energy sector.

Polyester has been the cornerstone of the textile printing industry for decades. Its compatibility with the digital sublimation process—a cost-effective, simple technology—has driven exponential growth in polyester printing. However, the very characteristics that make polyester well suited for sublimation printing render this printing technique unsuitable for other materials, such as cotton and some blended fibres, leaving a significant gap in the market.

This gap was, until recently, partially filled by direct-to-textile printing. However, this method requires substantial initial investments in equipment and heavily relies on the time- and resource-consuming pre- and post-processing of fabrics to ensure colourfastness, colour accuracy, and compatibility with different substrates. Consequently, a need arose for a more sustainable and cost-effective solution that could cater to a wider range of textiles.

In response to this demand, Mimaki spent six years developing a breakthrough technology, TRAPIS, a simple two-step textile transfer printing solution, consisting of only an inkjet printer and a high-pressure calender. The design of choice is printed by the inkjet printer onto the company’s groundbreaking Texcol® pigment ink transfer paper. This is then transferred to the application via the calender.

Entirely removing the treatment stages means that printing on non-polyester materials has gone from an expensive and time-consuming task to one that is simple, cost-efficient and more sustainable.

Ideal for home textiles and soft signage which often require vibrant colours but varied materials, this technology gives printers the ability to print on a wide variety of materials, including natural fibres like cotton and silk without losing stretchability or colourfastness. All this can be done with just one type of ink, making the process flexible and adaptable to customer demands.  

The pre-treatment and washing of the fabric is often needed in digital dye printing, producing a significant amount of wastewater in the process. TRAPIS eliminates those stages altogether and is almost entirely waterless, saving around 14.5 litres per square metre of water, an almost 90% decrease in comparison to digital dye printing .

Additionally, this eliminates the need for wastewater treatment facilities, which can be both expensive and constrictive when it comes to where the solution is installed.

The Cleanzone, the trade fair for cleanroom and purity technology, hygiene and contamination control, took place in Frankfurt am Main on September 25 and 26, 2024. The Cleanzone Award is presented at the trade fair to recognize groundbreaking advances in innovation, automation, sustainability and efficiency in the field of cleanroom technology. This year, the award went to the German Institutes of Textile and Fiber Research Denkendorf (DITF) and the Dastex Group GmbH for the development of a test method for cleanroom garments - the ReBa².

With the Realistic Bacterial Barrier (ReBa²) test method, the DITF offer a new biological method for determining the bacterial penetration for cleanroom garment textiles. Particularly in the manufacturing of sterile pharmaceuticals, bacteria, skin flakes and fiber particles that can originate from persons and their clothing pose a risk to the products manufactured in the cleanroom. Special cleanroom garments have the task of minimizing this risk. To assess the barrier function, the “bacterial penetration” is determined, among other properties. This provides information on how many bacteria from the human skin flora pass through the cleanroom garments to the outside when worn.

The ReBa² test method largely reproduces the situation when wearing cleanroom garments and thus enables a meaningful determination of the bacterial penetration. It is also possible to consider numerous test scenarios. In addition to the influence of intermediate garments worn under the cleanroom garments, the sweating process or the pre-wetting of the cleanroom garments by liquid splashes in the manufacturing process or by disinfectants can also be tested. The method was developed at the DITF in collaboration with the Dastex Group GmbH.

At this year's CINTE Techtextil fair in Shanghai, DILO received the innovation award for its intensive needling technology “MicroPunch”. Recent developments in energy costs, particularly for electricity and gas, and given the increasing shortage of water resources, have led to a shift in thinking over the past few years. Together with economic efficiency, the evaluation of the environmental impact of production has become increasingly important.

For DILO, this meant focusing on needling technology for the fine and lightweight nonwoven sector over the last years. The individual elements of the intensive needling technology underwent a complete revision. It became clear that the high production rates could only be achieved using the two-dimensional kinematics of the needle beam of "HyperPunch" or "CycloPunch." The necessary high feed rates of around 50 mm per stroke, coupled with the highest stitching densities to achieve good abrasion resistance, led to a need of a significant increase of the number of needles and needle density—almost doubling from approximately 20,000 needles/meter/board to around 45,000 needles/meter/board. It also became obvious that ensuring a high efficiency rate in production also required the careful attention to a quick assembly of the needle boards with needle modules. A completely new approach was needed in the design and construction of the needle boards to enable rapid module exchange and achieve a very high mechanical precision.

Previously, needling technology was primarily used for a surface weight range starting at 100 g/m² up to several kilograms per m². The expansion into the range below 100 g/m², and potentially down to 30 g/m², now completes the applicability of needling technology. The intensive needling technology "MicroPunch" opens up an economical field for a wide variety of lightweight nonwoven fabrics that can be produced by a pure mechanical processes. The product characteristics achieved, such as abrasion resistance, are comparable to those of hydroentangeld nonwovens. Needled fabrics tend to have more volume and more stretch while offering similar tensile strength values. These special quality characteristics are particularly interesting for applications in hygiene, medicine, cosmetics, and for technical products.

With this new development, the energy required to produce lightweight nonwoven fabrics has been reduced up to approximately 75% compared to other bonding technologies of this segment.

A collaboration that unites Monforts’ dyeing and finishing equipment, BW Converting’s Baldwin TexCoat G4™ digital spray technology and Archroma’s chemistries towards sustainable solutions is charting the course for the future of sustainable textile finishing.

Together, the three companies will support dyeing and finishing manufacturers, a critical part of the textile supply chain, in their development projects, boosting the quality and performance of their finished products, while at the same time maximizing the productivity and resource utilization of the finishing application process.  

Kicking off the partnership in the second half of this year, Monforts will install BW Converting’s full-width Baldwin TexCoat digital spray unit on a stenter frame at its Advanced Technology Center (ATC) at its headquarters in Mönchengladbach, Germany.

“Our ATC already houses two full Montex stenter finishing lines engineered to accommodate an extremely diverse range of processes, in addition to a Thermex range for the continuous dyeing of denim and other woven fabrics, a full color kitchen and a number of lab-scale systems for smaller batch trials,” explained Monforts Junior Technologist Saskia Kuhlen. “It enables our customers to test their own textiles and technical fabrics under fully confidential, real production conditions and using the results from these trials we are also able to make recommendations for improving many fabric finishes. The new TexCoat installation will make an important contribution to what we can achieve.”
 
TexCoat G4 revolutionizes the traditional water- and energy-intensive pad-dry-cure finishing process by precisely applying chemistry including softeners, antimicrobials, durable water repellents, flame retardants, resins and most other water-based chemicals across the textile surface only where it is required, on one or both sides of the fabric. The system can therefore reduce water, chemistry and energy consumption by up to 50% compared to traditional pad application processes.

The TexCoat G4 installation brings together the surface functions, fabric transport and thermal processing technology of Monforts stenter frames with Archroma’s specialty chemicals, applied with TexCoat’s contactless precision, to achieve optimum absorption and maximum efficacy, exceeding the performance of traditional pad applications.

“Archroma’s commitment to advancing sustainability solutions for technical textiles has led to a pivotal partnership with Baldwin, where the benefits of contactless precision spray combined with our innovative solutions have helped textile manufacturers achieve greater energy and water savings,” said Michael Schuhmann, Global Marketing Segment Manager for Technical Textiles, Archroma Textile Effects. “We are thrilled to take the partnership to the next level with the integration of a renowned equipment expert. Together, we will bring the best of our expertise in sustainable technologies to our customers around the world.”

“Baldwin has enjoyed a great relationship with Monforts and Archroma over the last few years,” added Rick Stanford, Baldwin’s Vice-President of Business Development for Textiles “Individually, we are working hard to assist our customers to achieve their sustainability and environmental targets but this is the first time the three companies have committed to working together with a focus on bringing transformative change to the dyeing and finishing space. It will result in significantly lower energy, chemical and water consumption with increased productivity and higher quality.  We strongly believe that this partnership will be greater than the sum of its parts.”

Beyond textile finishing, Monforts, Baldwin and Archroma will work together to develop a versatile offering that will include coloration concepts and in the not-too-distant future the partners additionally plan to expand their collaboration to continuous spray dye applications developed by Baldwin.
