From the Sector

The combination of high strength and rigidity with sustainability and a neutral carbon footprint makes flax the ideal raw material for natural fibre-reinforced plastics. vombaur offers composite textiles made of this natural fibre for the automotive, wind power, construction or sports industries and many other sectors.

Flax fibres are rigid and tear-proof. They have natural bactericidal properties, are virtually antistatic, stain resistant and easy to spin. Humans have taken advantage of these properties to manufacture robust, stain-resistant and lint-free textiles. Between the late 19^th and late 20^th centuries, cotton largely replaced natural fibres. Because flax can be grown in Europe and consumes less energy and water than cotton production, the material's importance is currently growing again, for both clothing and composites. Regional textile value added chains in Europe – flax makes them possible.

Ideal mechanical properties
vombaur makes the mechanical properties of flax usable for lightweight design. Because flax fibres are particularly rigid and tear-resistant, they ensure great stability in natural fibre-reinforced plastics (NFRPs). And thanks to their low density of 1.50 g/cm3, the fibres weigh virtually nothing. On top of this, fibre-reinforced plastics are less prone to splintering than glass fibre-reinforced plastics.

Excellent carbon footprint
The cultivation of flax binds CO₂ and the production of natural fibre-reinforced plastics (NFRPs) generates approximately one third less CO₂ emissions compared with conventional fibre-reinforced plastics. Energy consumption is substantially lower. This saves resources. The use of flax fibre tapes by vombaur in lightweight design applications also improves the product's carbon footprint and contributes to a secure, regional supply chain.

Recycling without impacting on quality
Flax offers another sustainability benefit: more recycling cycles than glass- or carbon fibre-reinforced plastics – without impacting on quality. Thermoplastic fibre-matrix prepregs are melted and reused in the recycling process. The natural fibres can be used in other products such as natural fibre-reinforced injection moulded parts.

Sustainable product developments for many industries
"Orthoses for high-performance sports, high-tech skis, wind turbines, components for the automotive industry or aerospace, but also modern window profiles – the application scope for our lightweight design flax tapes is amazingly diverse", as Carl Mrusek, Chief Sales Officer at vombaur explains. "After all, wherever flax tapes are used, three key properties come together: light weight, strength and sustainability".

On the occasion of the 2023 UCI Cycling World Championships, the Union Cycliste Internationale chose Santini to make the bibs from recyclable materials. The UCI's partner brought together a pool of companies, all in the Bergamo area (Italy): RadiciGroup, Sitip, EFI Reggiani and Acerbis.

In 2022, the Union Cycliste Internationale released the UCI Climate Action Charter, which lays out an action plan to advance the environmental sustainability of the sport with a specific principle to reduce waste and accelerate the transition to a circular economy. This year, the UCI Cycling World Championships, which will be held from 3 to 13 August, are bringing together most of the cycling disciplines in a single location: Glasgow and across Scotland.

To mark the occasion, the UCI turned to its Official Partner, Santini, to make the bibs that the staff (judges, volunteers, commissaires etc.) and accredited photographers wear throughout the event. The bibs are "eco-designed", which means they are specifically created to have a second life after use. Once the event is over, the bibs could be collected and sent to RadiciGroup and transformed into new material, to be then processed by Acerbis to create X-Elite handguards for mountain bikes. This project is a concrete example of the circular economy at work, allowing 100% of the materials used to be recovered.

To optimise the production cycle of the bibs for the 2023 UCI Cycling World Championships, the products must be eco-friendly from the very first phase. The fabrics were therefore made from Italian nylon yarn produced by RadiciGroup. The choice of nylon – an infinitely recyclable thermoplastic material – is intertwined with UCI's sustainability goals for "limited-use" garments: RadiciGroup was able to channel its know-how and expertise in the field of chemistry to create "circular" bibs, working alongside the other partners. As the innovative yarn selected by RadiciGroup allows for easy and high-quality printing, the fabric is also customisable. The yarn is then provided to Sitip to create the "ARAS NG" warp-knitted fabric (95 g/100 m2): a recyclable single-fibre material made from 100% polyamide. The resulting fabric is the first nylon of its kind, designed to meet the transfer printing needs of the third project partner, EFI Reggiani, as well as the recyclability standards requested by RadiciGroup. The choice of fabric was born from extensive applied research, in which EFI Reggiani tested a wide range of fabrics to find the best colour results and the best resistance to rubbing and perspiration, which is vital for the bibs' intended use. In addition to using the new GOTS-certified EFI Reggiani IRIS Plus water-based inks, EFI Reggiani opted for a printing solution on transfer paper that does not consume water and requires a minimal amount of energy per square metre. Finally, the white fabric from Sitip and the transfer paper printed by EFI Reggiani arrived at Santini, who were responsible for transferring all the graphics for the 2023 UCI Cycling World Championships bibs from the paper onto the fabric. Santini also took care to assemble the garments using only thread and components made from nylon or chemically similar materials, allowing the bibs to enter the recycling process at the end of their lives without any further processing.                   

Increasing energy and resource efficiency in the construction sector will be key to the EU’s ambition of achieving climate neutrality by 2050. By enabling the manufacture of strong, durable and lightweight products, composite materials can help the construction sector improve its environmental sustainability, as well as reduce total lifecycle costs. The latest EPTA industry briefing, Pultruded composites contribute to a more sustainable future for construction, discusses how pultruded composites answer the need for materials offering high performance, faster installation, corrosion resistance and low maintenance.

The report is available to download from the EPTA website.

The future of construction
As one of the largest global users of energy and raw materials, the construction industry is under immense pressure to improve its sustainability. At the same time, it must respond to demands for improved performance and reduced total cost of ownership. New materials will be needed to minimise the use of natural resources, enable a reduction of carbon footprint and facilitate circular economy practices. Choosing the optimum materials required for durability throughout the lifecycle will be increasingly important. A shift to off-site production is also forecast, where factory-controlled environments and automated processes can improve quality control, lower waste, and reduce work on site.

Lightweight pultruded parts can be pre-assembled into modules or complete structures in the factory for faster installation on site. Lightweight profiles lower energy use during transportation and installation, and a longer service life combined with minimal maintenance can deliver a reduced through-life carbon footprint. Pultruded parts such as profiles, gratings, beams, tubes and planks are increasingly found in a range of building, construction and infrastructure applications. Examples include bridge decks, fencing, stairs and handrails, train platforms, cladding, utility poles, modular building concepts, and window frames.

One application offering large growth potential for composites is bridges. Composite bridges are being designed to provide a service life of 100 years and unlike steel bridges do not require regular repainting to protect them from corrosion. Over recent years, pultruded glass fibre composite has become a highly popular choice for pedestrian and cycle bridges. Pre-fabricated ‘easy fit’ bridge decking planks, pre-assembled bridge modules and complete bridge ‘kits’ are now available. Corrosion-resistant composite bridges are ideal for use near water or on the coast, and in remote locations where regular maintenance operations would be difficult. A composite bridge can deliver the same performance as a steel structure with a weight saving of up to 50% or more. This enables more streamlined bridge designs which require less substantial supporting structures and foundations, greatly reducing consumption of materials and energy. Lightweight also results in easier logistics and simplified installation. Pultruded are more easily transported to the construction site, with lower fuel consumption, and easier to move on site, often reducing labour requirements and the capacity of lifting equipment.

A lifecycle approach
As the construction industry looks to the future, the environmental and economic benefits of composite materials linked to easier logistics and installation, durability and low maintenance are becoming increasingly valued. More projects are demonstrating the benefits of composite materials and standards covering the design, fabrication and installation of pultruded profiles are making it easier for the construction industry to use them. With ongoing development and collaboration, pultrusion has the potential to contribute to a more sustainable future for construction and many other industries. EPTA will continue to promote the advancement of pultrusion technology and its applications and foster sustainable practices within the industry.

An openly accessible online energy savings calculator for all users of powder coatings has been launched by AkzoNobel.

Pulcra Chemicals and Inditex develop Sustineri Coloring, a combined pretreatment and dyeing process for cotton and polyester/cotton resulting in water, time and energy savings. This process is the result of a joint research between Pulcra Chemicals and Inditex with the goal to mitigate the impact of standard dyeing processes and to reduce the use of natural resources.

Sustineri Coloring is based on newly engineered process chemicals which allow a one bath pretreatment and dyeing process for dark, medium and light shades of cotton and polyester/cotton fabrics by exhaust method. This results in shorter processing time and less use of water and energy.

The process is already used by selected mills and it showed that Sustineri Coloring is reducing in pretreatment and dyeing the processing time by up to 60 % and the water and energy consumption by up to 80 and 60% respectively. The state-of-the-art products allow a one bath treatment which is the key in saving resources.

Archroma, a leader in specialty chemicals towards sustainable solutions, is teaming up with COLOURizd™, an innovator specializing in sustainable textile dyeing technologies, to set a new standard for the eco-friendlier production of sustainable textiles.

The new collaboration will enable fabric mills and brands to combine Archroma pigment coloration solutions with the COLOURizd™ QuantumCOLOUR™ yarn-coloring technology to produce high-quality, high-performance textiles with maximum consumer appeal and minimal environmental impact.

Conventional fiber-reactive methods of dyeing cellulosic and synthetic yarns are multi-step resource-intensive processes that use up to 95 liters of water per kilograms of colored yarn and discharge approximately 94 liters of effluent.

In contrast, the innovative QuantumCOLOUR™ process injects pigment and a binder directly into the yarn, using only 0.95 liters of water per kilograms of colored yarn while producing zero effluent. This represents an unprecedented reduction of 98% in water consumption alongside zero wastewater discharge, zero discharge of harmful chemicals, 73% decrease in carbon footprint and 50% reduction in energy use.*

With Archroma, textile manufacturers and apparel brands can add further value to the QuantumCOLOUR™ process with tailor-made system solutions, including JUST COLOR. This formaldehyde-free** pigment coloration system is based on Archroma’s revolutionary Printofix® pigment dispersions and Helizarin® binders to deliver exceptionally soft fabrics with high fastness and durability, while also enabling energy and chemical savings and higher productivity.

How does a future-proof, circular and sustainable plastics economy look like? The answer is a balance ranging from plastics reduction to a sustainable use of recyclable plastics. After all, the increasing demand for plastics in high-value applications such as food packaging, car parts or synthetic textiles requires a holistic change. With four strategic approaches, researchers from the German institute Fraunhofer UMSICHT and the Dutch institute TNO now provide insights into how this future scenario could look like in their recently published white paper "From #plasticfree to future-proof plastics". Both organizations also start a hands-on platform for plastics in a circular economy: European Circular Plastics Platform – CPP aimed at removing existing barriers and sharing of promising solutions.

Versatile and inexpensive materials with low weight and very good barrier properties: That's what plastics are. In addition to their practical benefits, however, the materials are also associated with a significant share of mankind's greenhouse gas emissions. The production and use of plastics cause environmental pollution and microplastics, deplete fossil resources and lead to import dependencies. At the same time, alternatives - such as glass packaging - could cause even more environmental burden or have poorer product properties.

Researchers from TNO and Fraunhofer UMSICHT have elaborated a white paper that provides a basis for the transformation of plastics production and use. They consider the integration of the perspectives of all stakeholders and their values and the potential of current and future technologies. In addition, the functional properties of the target product, the comparison with alternative products without plastics, and their impact in a variety of environmental, social and economic categories over the entire life cycle are crucial. In this way, a systematic assessment and ultimately a systematic decision as to where we can use, reject or replace plastics can be realized.

Strategies for the Circular Economy
As a result, the researchers describe four strategic approaches for transforming today's largely linear plastics economy into a fully circular future: Narrowing the Loop, Operating the Loop, Slowing the Loop, and Closing the Loop. By Narrowing the Loop, the researchers recommend, as a first step, to reduce the amount of materials mobilized in a circular economy. Operating the Loop refers to using renewable energy, minimizing material losses, and sourcing raw materials sustainably. For Slowing the Loop, measures are needed to extend the useful lifetime of materials and products. Finally, for Closing the Loop, plastics must be collected, sorted and recycled to high standards.

Individual strategies fall under each of the four approaches. While the ones under Operating the Loop (O strategies) should be applied in parallel and as completely as possible. According to the researchers, the decision for the strategies in the other fields (R strategies) requires a complex process: “Usually, more than one R-strategy can be considered for a given product or service. These must be carefully compared in terms of their feasibility and impact in the context of the status quo and expected changes”, explains Jürgen Bertling from Fraunhofer UMSICHT. The project partners have therefore developed a guiding principle for prioritization based on the idea of the waste hierarchy.

A holistic change, as we envision it, can only succeed if science, industry, politics and citizens work together across sectors. “This implies several, partly quite drastic changes at 4 levels: legislation and policy, circular chain collaboration, design and development, and education and information. For instance, innovations in design and development include redesign of polymers to more oxygen rich ones based on biomass and CO2 utilisation. Current recycling technologies have to be improved for high quantity and quality recycling,” explains Jan Harm Urbanus from TNO.

Hands-on platform for cross-sector collaboration
“Therefore, in a next step, TNO and Fraunhofer UMSICHT are building a hands-on platform for plastics in a circular economy: European Circular Plastics Platform – CPP," explains Esther van den Beuken, Principal Consultant from TNO. It will give companies, associations and non-governmental organizations the opportunity to work together on existing barriers and promising solutions for a Circular Plastics Economy. The platform will also offer its members regular hands-on workshops on plastics topics, roundtable discussions on current issues, and participation in multi-client studies on pressing technical challenges. Regular meetings will be held in the cross-border region of Germany and the Netherlands as well as online. The goal is to bring change to the public and industry.

CELLIANT® with REPREVE®, introduced by Hologenix with global textile solutions provider UNIFI®, makers of REPREVE®, has been awarded a Top 5 Selection in the Accelerated Eco category of the Spring/Summer ISPO Textrends 2025 Awards.
