From the Sector

The “Cellulose Fibres Conference 2024” held in Cologne on 13-14 March demonstrated the innovative power of the cellulose fibre industry. Several projects and scale-ups for textiles, hygiene products, construction and packaging showed the growth and bright future of this industry, supported by the policy framework to reduce single-use plastic products, such as the Single Use Plastics Directive (SUPD) in Europe.

40 international speakers presented the latest market trends in their industry and illustrated the innovation potential of cellulose fibres. Leading experts introduced new technologies for the recycling of cellulose-rich raw materials and gave insights into circular economy practices in the fields of textiles, hygiene, construction and packaging. All presentations were followed by exciting panel discussions with active audience participation including numerous questions and comments from the audience in Cologne and online. Once again, the Cellulose Fibres Conference proved to be an excellent networking opportunity to the 214 participants and 23 exhibitors from 27 countries. The annual conference is a unique meeting point for the global cellulose fibre industry.  

For the fourth time, nova-Institute has awarded the “Cellulose Fibre Innovation of the Year” Award at the Cellulose Fibres Conference. The Innovation Award recognises applications and innovations that will lead the way in the industry’s transition to sustainable fibres. Close race between the nominees – “The Straw Flexi-Dress” by DITF & VRETENA (Germany), cellulose textile fibre from unbleached straw pulp, is the winning cellulose fibre innovation 2024, followed by HONEXT (Spain) with the “HONEXT® Board FR-B (B-s1, d0)” from fibre waste from the paper industry, while TreeToTextile (Sweden) with their “New Generation of Bio-based and Resource-efficient Fibre” won third place.

Prior to the event, the conference advisory board had nominated six remarkable innovations for the award. The nominees were neck and neck, when the winners were elected in a live vote by the audience on the first day of the conference.

First place
DITF & VRETENA (Germany): The Straw Flexi-Dress – Design Meets Sustainability
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.

Second place
Honext Material (Spain): HONEXT® Board FR-B (B-s1, d0) – Flame-retardant Board made From Upcycled Fibre Waste From the Paper Industry
HONEXT® FR-B board (B-s1, d0) is a flame-retardant board made from 100 % upcycled industrial waste fibres from the paper industry. Thanks to innovations in biotechnology, paper sludge is upcycled – the previously “worthless” residue from paper making – to create a fully recyclable material, all without the use of resins. This lightweight and easy-to-handle board boasts high mechanical performance and stability, along with low thermal conductivity, making it perfect for various applications in all interior environments where fire safety is a priority. The material is non-toxic, with no added VOCs, ensuring safety for both people and the planet. A sustainable and healthy material for the built environment, it achieves Cradle-to-Cradle Certified GOLD, and Material Health CertificateTM Gold Level version 4.0 with a carbon-negative footprint. Additionally, the product is verified in the Product Environmental Footprint.

Third Place
TreeToTextile (Sweden): A New Generation of Bio-based and Resource-efficient Fibre
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 next conference will be held on 12-13 March 2025.

The annual highlight of the industry is the International Conference on Cellulose Fibres in Cologne, where the latest innovations were showcased: new cellulose fibre technologies for various feedstocks and a wide range of hygiene and textile products as well as alternatives to plastics and carbon fibre for lightweight constructions.

This year, for the first time, there were 230 participants from 27 countries. About 60 were able to attend on site – with strict Corona safety measures – while the others were able to attend online and participate in questions and discussions.

The conference gave deep insights into the promising future of cellulose fibres, which fit perfectly into the current trends of circular economy, recycling and sustainable carbon cycles.

An important focus at the conference was alternative sources of cellulose. The increasing demand for cellulose fibres cannot be met in the long run with wood and used textiles alone. At the conference, a variety of agricultural by-products and biogenic waste were presented in presentations and panel discussions, such as orange and banana peels, grain and hemp straw. Much of this is high-volume and has not been put to high-value use so far. Exciting opportunities for the future cellulose fibre industry.

Innovation Award
Live at the conference, host nova-Institute and award sponsor GIG Karasek GmbH granted the “Cellulose Fibre Innovation of the Year” award to one of six highly interesting products.

• First Winner: Carbon Fibres from Wood – German Institutes of Textile and Fiber Research Denkendorf (Germany)

nova-Institute and YNCORIS together with CO₂ Value Europe are looking forward to applications for the innovation award “Best CO₂ Utilisation 2022”. The award will be granted at the well-established “Conference on CO₂-based Fuels and Chemicals”, 23–24 March 2022 in Cologne.

With the innovation award “Best CO₂ Utilisation 2022” together with YNCORIS and CO₂ Value Europe, the nova-Institute offers innovators in the CCU field the unique opportunity to present and market their carbon capture or carbon utilisation (Power-to-X) technology, CO₂-based fuel or chemical at one of the leading conferences on CO₂ as a raw material. The only requirement for participation in the competition is that the product is already on the market or about to be launched in near future.

Eleven leading companies from six countries founded the Renewable Carbon Initiative (RCI) in September 2020 under the leadership of nova-Institute (Germany). The aim of the initiative is to support and speed up the transition from fossil carbon to renewable carbon for all organic chemicals and materials.

Besides Lenzing, these ten companies are founding members of the RCI, which also form the Core Advisory Board: Beiersdorf (Germany), Cosun Beet Company (The Netherlands), Covestro (Germany), Henkel (Germany), LanzaTech (USA), NESTE (Finland), SHV Energy (The Netherlands), Stahl (The Netherlands), Unilever (UK) and UPM (Finland).

The Renewable Carbon Initiative (RCI) addresses the core problem of climate change, which is extracting and using additional fossil carbon from the ground. The vision is stated clearly: By 2050, fossil carbon shall be completely substituted by renewable carbon, which is carbon from alternative sources: biomass, direct CO2 utilisation and recycling. The founders are convinced that this is the only way for chemicals, plastics and other organic materials to become sustainable, climate-friendly and part of the circular economy – part of the future.

Robert van de Kerkhof, Chief Commercial Officer of the Lenzing Group: „We at Lenzing believe that we need to create strategic partnerships to implement systemic change. Therefore, we support the Renewable Carbon Initiative. First of all, because it is the right thing to do and, second, it is also fully aligned with our corporate strategy. Therefore, we are part of the RCI from the beginning and its commitment to start acting now.”

Michael Carus, CEO of nova-Institute and head of the Renewable Carbon Initiative: “This is about a fundamental change in the chemical industry. Just as the energy industry is being converted to renewable energies, so renewable carbon will become the new foundation of the future chemical and material industry. The initiative starts today and will be visibly present from now on. We want to accelerate the change.”

The main avenues on which the initiative wants to deliver change are threefold. One, the initiative strives to create cross-industry platforms that will demonstrate feasibility of renewable carbon in tangible activities. Two, one main target will be to advocate for legislation, taxation and regulation changes to give renewable carbon a level commercial playing field to play on. Finally, the third avenue will be to create a wider pull for sustainable options by raising awareness and understanding of renewable carbon level amongst the business community and the wider public.

The Renewable Carbon Initiative has made a powerful start with eleven international member companies and the personal support of more than 100 industry experts. The initiative hopes to gain many additional members and supporters in the upcoming months to keep the strong momentum of the initiative. Working together, RCI will support and accelerate the transition from fossil to renewable carbon for all organic chemicals and materials.

In the end, the aim is as complex as it is simple: renewable energy and renewable carbon for a sustainable future. Within the RCI Lenzing will especially focus on further greening up the textile and nonwoven businesses. Here we will promote this concept and encourage our partners to become a part of this vision.
