For the third time, nova-Institute awards the “Cellulose Fibre Innovation of the Year” award in the frame of the “Cellulose Fibres Conference 2023” (8-9 March 2023). The conference advisory board nominated six remarkable products, including cellulose fibres from textile waste, banana production waste and bacterial pulp, a novel technology for producing lyocell yarns and a hygiene product. The innovations will be put to the vote of the conference audience on the first day of the event, with the awards ceremony taking place in the evening. The innovation award “Cellulose Fibre Innovation of the Year 2023” is sponsored by GIG Karasek (AT).

Here are the six nominees
Vybrana – The new generation banana fibre – GenCrest Bioproducts (India)
Vybrana is a Gencrest’s Sustainable Cellulosic Fibre upcycled from agrowaste. Raw fibres are extracted from the Banana Pseudo stem at the end of the plant lifecycle. The biomass waste is then treated by the Gencrest patented Fiberzyme technology. Here, cocktail enzyme formulations remove the high lignin content and other impurities and help fibre fibrillation. The company's proprietary cottonisation process provides fine, spinnable cellulose staple fibres suitable for blending with other staple fibres and can be spun on any conventional spinning systems giving yarns sustainable apparel. Vybrana is produced without the use of heavy chemicals and minimized water consumption and in a waste-free process where balance biomass is converted to bio stimulants Agrosatva and Bio Fertilizers & organic manure.

HeiQ AeoniQ™ – technology for more sustainability of textiles – HeiQ (Austria)
HeiQ AeoniQ™ is the disruptive technology and key initiative from HeiQ with the potential to change the sustainability of textiles. It is the first climate-positive continuous cellulose filament yarn, made in a proprietary manufacturing process and the first to reproduce the properties of polyester and nylon yarns in a cellulosic, biodegradable, and endlessly recyclable fibre.
HeiQ AeoniQ™ can be manufactured from different cellulosic raw materials such as pre- and post-consumer textile waste, biotech cellulose, and non-valorized agricultural waste, such as ground coffee waste or banana peels. It naturally degrades after only 12 weeks in the soil. Each ton of HeiQ AeoniQ™ saves 5 tons of CO2 emissions. The first garments made with this innovative cellulosic filament fiber were commercially launched in January 2023.

TENCEL™ LUXE – lyocell filament yarn – Lenzing (Austria)
TENCEL™ LUXE is LENZING’s new versatile lyocell yarn that offers an urgently needed sustainable filament solution for the textile and fashion industry. A possible botanical alternative for silk, long-staple cotton, and petrol-based synthetic filaments, is derived from wood grown in renewable, sustainably managed forests, and produced in an environmentally sound, closed-loop process that recycles water and reuses more than 99 % of organic solvent. Certified by The Vegan Society, it is suitable for a wide range of applications and fabric developments, from finer high fashion propositions to denim constructions, seamless and activewear innovations, and even agricultural and technical solutions.

Nullarbor™ – Nanollose & Birla Cellulose (Australia/India)
In 2020, Nanollose & Birla Cellulose started a journey to develop and commercialize tree-free lyocell from bacterial cellulose, called Nullarbor™. The name derives from the Latin “nulla arbor” which means “no trees”. Initial lab research at both ends led to a joint patent application with the patent “production of high-tenacity lyocell fibres made from bacterial cellulose”.
Nullarbor is significantly stronger than lyocell made from wood-based pulp; even adding small amounts of bacterial cellulose to wood pulp increases the fibre toughness. In 2022, the first pilot batch of 260kg was produced with 20 % bacterial pulp share. Several high-quality fabrics and garments were produced with this fibre. The collaboration between Nanollose & Birla Cellulose now focuses on increasing the production scale and amount of bacterial pulp in the fibre.

Circulose® – makes fashion circular – Renewcell (Sweden)
Circulose® made by Renewcell is a branded dissolving pulp made from 100 % textile waste, like worn-out clothes and production scraps. It provides a unique material for fashion that is 100 % recycled, recyclable, biodegradable, and of virgin-equivalent quality. It is used by fibre producers to make staple fibre or filaments like viscose, lyocell, modal, acetate or other types of man-made cellulosic fibres. In 2022, Renewcell, opened the world’s first textile-to-textile chemical recycling plant in Sundsvall, Sweden – Renewcell 1. The plant will eventually reach 120,000 tons of annual capacity.

Sparkle sustainable sanitary pads – Sparkle Innovations (United States)
Globally, around 300 billion period products are discarded every year, resulting in millions of tons of non-biodegradable waste. Since most conventional sanitary pads contain up to 90 % plastics, they do not biodegrade for around 600 years. Sparkle has designed sustainable, plastic-free, biodegradable and compostable Sparkle sanitary pads. From product to packaging, they are made up of around 90 % cellulose-based materials with top sheet, absorbent core, release paper, wrapping paper and packaging made of cellulose-based fibres. Whether Sparkle pads end up in a compost pit, are incinerated or end up in a landfill, they are a more sustainable alternative compared to conventional pads that contain large amounts of plastics, complex petro-chemical based ingredients and artificial fragrances. When tested according to ISO 14855-1 by a leading independent lab in Europe, Sparkle pads reached over 90 % absolute biodegradation within 90 days in commercial composting conditions.

In occasion of the next edition of Pitti Uomo, Bemberg™ by Asahi Kasei – the unique fiber with a circular economy footprint obtained from cotton linters through a closed-loop process ensuring certified sustainability credentials through its transparent and traceable approach- reveals a very special Bemberg™ fabrics smart range dedicated to premium denimwear.

This has been made possible thanks to the partnership with PureDenim, a leading Italian company whose strategy since 10 years is based on an entire re-design of the production system, inspired by circular economy principles that combines technology and innovative materials in order to offer the highest levels of design, innovation and real responsible values derived from an holistic approach to sustainability.
The “Blue di Cupro” collection is made with seven fabrics made with Bemberg™, either 100% Bemberg™ or in blend with cotton, wool, and it applies the most advanced Pure Denim Technologies. The Blue di cupro fabrics made with Bemberg™ will also be dyed with “Smart Indigo” an indigo dye technology internally produced by PureDenim, through a chemical-free production. The only elements involved are: water, indigo pigments, and electricity. In terms of finishing, fabrics’ looks and performances are enhanced by the “Eco Sonic” ultrasounds finishing technology which brings significant reduction of water used, increased aesthetic features and controlled discoloration. And last but not least every yarn used at PureDenim is protected by NaturalReco® a 100% natural product that completely SUBSTITUTE the use of plastic films that are one of the key causes of microplastic emission for denim application.

“Blue” seems to be the new colour of Bemberg™, in fact, the company in early November 2022 announced, at the Blue Friday initiative by UNESCO's Intergovernmental Oceanographic Commission (IOC), the achievement of the OK biodegradable MARINE certification, which guarantees the biodegradability of its products even in the marine environment, as certified by TÜV AUSTRIA, meaning a lot in the context of microplastics in water issue solutions. This Bemberg™ certification’s achievement comes on top of other key ones such as the INNOVHUB report that confirms Bemberg™ biodegradability in soil without releasing hazardous substances, the RCS by Textile Exchange, and the Oeko-Tex Standard 100 and ISO 14001 corporate certifications.

RHEON LABS, a fast-growing materials technology company based in Battersea, London, has completed an extensive 6 month trial with FET, a world leader in laboratory and pilot meltspinning equipment. Backed by a £173,000 grant from Innovate UK for feasibility studies, RHEON LABS has further developed its RHEON™ technology, a reactive polymer that dynamically stiffens when subjected to force. The technology can control energy of any amplitude or frequency, from small vibrations to forces at ballistic-speeds and therefore has a wide range of applications.
 
This Innovate UK Smart Grant-backed project aims to develop a hyper viscoelastic fibre from RHEON™ which displays high strain-rate sensitive properties. Creating a fibre with unique strain-rate sensitive properties will be a world first. It will enable the creation of a 'breakthrough-generation' of stretch textiles that can actively absorb, dampen and control energy during movement, rather than simply acting as a spring.

For close-fitting activewear and sports bras, the ability to actively control muscle mass or soft tissue movement during exercise will be a game-changing advancement. It will allow brands to engineer garments that relax during everyday use but actively stiffen during exercise for improved support and performance.
The Innovate UK grant was awarded under the category of Hyper-Viscoelastic Fibre Extrusion for Textile Manufacture. Fibre Extrusion Technology Limited (FET) enabled the customer trials at its bespoke Fibre Development Centre in Leeds, England using its in-house FET-103 Monofilament meltspinning facilities, in harness with RHEON and FET technical operatives. The next phase will be to upscale the trials of preferred materials on RHEON’s own new FET-103 meltspinning line, with FET’s continued support and expertise on hand.
 
Creating a fibre with unique strain-rate sensitive characteristics could be as radical a change in the market as the initial introduction of stretch fibre with the launch of Lycra™. The textiles would have a multitude of beneficial properties and would provide significantly less compression in the garment than conventional materials, substantially improving user comfort, support and performance.

Catering to the acoustic requirements of electric vehicles, Autoneum has extended its concepts for noise-reducing engine encapsulations to new applications related to electric drives. Hybrid-Acoustics PET and the foam-based alternatives Hybrid-Acoustics FLEX and Fit FLEX ensure optimum noise protection in e-cars and thus improve driving comfort. All three technologies are characterized by a high acoustic performance tailored to specific customer needs and zero waste production.

Disturbing noises such as the high-frequency sounds of e-motors and other electric devices or the whining noise of the gearbox are posing new acoustic challenges for vehicle manufacturers worldwide. Anticipating the increasing demand for sound-reducing components in both the front and the rear of e-cars early on, Autoneum has expanded its technologies for noise protection in the engine bay to new tailor-made applications for electric vehicles.

With the fibrous technology Hybrid-Acoustics PET and the two foam alternatives Hybrid-Acoustics FLEX and Fit FLEX, the Company offers three standardized technologies that reduce noise directly at the source, thereby improving driver comfort. All three technologies are produced waste-free and their adaptive capacity to different sizes and shapes allows for a broad spectrum of uses in electric vehicles: from e-motor encapsulations to the reduction of noise and vibration of inverters, gearbox, pumps and compressors. By offering both fibrous and foam-based variants, Autoneum is able to flexibly cater to individual customer needs and preferences with regard to material, acoustic concept, sustainability and costs.

In terms of sustainable noise protection in the engine bay, Autoneum’s patented innovation Hybrid-
Acoustics PET sets the tone: it is made of 100 percent PET with up to 50 percent recycled fibers; cut-offs in production are reclaimed, processed and reused and the material can be fully recycled at the end of product life. The unique textile technology, which is part of the Company’s sustainability label Autoneum Pure, is particularly suited to attenuating high-frequency sounds of the electric drive unit and offers the optimum balance of absorption and insulation. Moreover, components made of Hybrid-Acoustics PET are up to 40 percent lighter compared to standard insulators.

To accommodate the differing preferences of vehicle manufacturers, Autoneum has complemented its lightweight textile technology with two foam-based alternatives. Since the foam is injected in both technologies, no waste is generated during production either. Hybrid-Acoustics FLEX is based on the same acoustic concept as Hybrid-Acoustics PET, but the decoupler is made of foam instead of felt. Autoneum’s Fit FLEX, on the other hand, combines the foam decoupler with an injection molded heavy layer. Thanks to the high geometrical adaptability of foam to even complex shapes, both technologies offer outstanding acoustic performance in the insulation of e-motors and other noise sources in electric vehicles. Furthermore, the absorbing or insulating acoustic quality of the foam can be flexibly tuned to specific customer needs.

• The plan for the reference plant is to be operational in 2025 in France (Longlaville) with a processing capacity of 50.000 tons of PET waste per year and creating 150 direct and indirect new jobs.
• Indorama Ventures, the world’s largest producer of recycled PET for beverage bottles, plans to co-invest in this project3 and will consider expanding Carbios’ unique biological recycling process at other PET sites4 for future developments.
• This strategic project is strongly supported by the French Government and the Grand-Est Region, with significant non-dilutive financing.

Carbios (Euronext Growth Paris: ALCRB), a pioneer in the development of enzymatic solutions dedicated to the end-of-life of plastic and textile polymers and Indorama Ventures (Bloomberg ticker: IVL.TB), one of the world-leading PET manufacturer, jointly announced a collaboration to build a manufacturing plant operating Carbios’ PET bio-recycling technology at Indorama Ventures’ PET production site in France (Longlaville, Meurthe-et-Moselle).

After having successfully started-up its demonstration plant in Clermont-Ferrand, Carbios is moving one step further towards the industrialization and commercialization by partnering with Indorama Ventures. The goal is to build and operate in France the world’s first industrial-scale enzymatic PET bio-recycling plant, with a processing capacity estimated at ca. 50.000 tons of post-consumer PET waste per year, equivalent to 2 billion PET bottles or 2.5 billion PET trays.

The capital investment required for the project is expected to be around €150 million for Carbios core technology, including in particular an additional purification step, which has been integrated into the process. In addition, an estimated €50 million investment will be allocated for the infrastructure preparation of the site. The project is expected to create approximatively 150 direct and indirect full-time jobs. In the coming months, Carbios expects to finalize a strong non-dilutive financial support from French Government and from the Grand-Est Region5, based on the offer received last week by Carbios, from the Minister of Industry, Agnès Pannier-Runacher and the President of Grand-Est Region, Jean Rottner.

This financial support will be conditional on the notification to the European Commission and on contractualization by French authorities. Carbios announced in its half-year results on the 30th September 2021 a cash position of €112 million. Since then, Carbios has also secured a €30 million loan from EIB.
