Cellulose Fibre Innovation of the Year 2023 – Cellulose Fibres Conference 2023, 8-9 March




Cellulose Fibres Conference 2023, 8-9 March

The only conference focused on cellulose fibres – in textiles, hygiene products and packaging


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.

Now, in 2022, the European Commission has made the thorough transition towards sustainability and circularity for different industries and especially the textile sector a main focus. The focus on textile is justified as the global textile production has almost doubled in the period between 2000 and 2015. Still less than 1 % of the global textile production is estimated to be recycled into new textiles at the end of life. The remaining 99 % of textiles go to landfilling, incineration or litter.

This demands a new way of thinking with regard to sustainability and circularity within the textile economy. This process already starts with the material selection of the fibres used for the textiles. Generally, textiles consist of fibres, which can be made from renewable and non-renewable resources. A first step towards improving the sustainability of textiles is the change from non-renewable to renewable fibres. In consequence, the textile industry shows a steadily increasing, enormous demand on renewable and sustainable fibres.

One effective solution towards ecodesign is the use of cellulose fibres. Cellulose is the main component of plant cell walls and a natural polymer. Therefore, cellulose is bio-based and biodegradable, even in marine-environments, where its degrading does not cause any microplastic. The different production technologies for extracting cellulose from plants can also be used for the recycling of cellulose which enables a circularity of the material.

With a compound annual growth rate (CAGR) between 5 and 10 %, cellulose fibres have been a success story within the textile market over the past decade. Similar growth rates are expected in the following years. This makes cellulosic fibres the fastest growing fibre group in the textile industry and therefore the largest investment sector in the global circular bio-economy.
