• Standard assesses fibre release, biodegradation and ecotoxicity for the first time

Testing service provider Hohenstein has worked with the project partners Trigema, Freudenberg, DBL ITEX and Paradies to create a new standardized test method for detecting and classifying the environmental effects of textiles during washing. DIN SPEC 4872 combines analysis of fibre release, biodegradability and ecotoxicity. The test method according to DIN SPEC 4872 shows how many fibres are released during textile laundering, how well these fibres degrade in wastewater and how harmful the fibre residues are to the environment.

Studies have shown that washing textiles releases microfibres into the wash water, which cannot be sufficiently retained by wastewater treatment plants. Synthetic fibres pose the greatest risk to the environment because of their longevity and inability to biodegrade. However, Hohenstein project manager Juliane Alberts does not give the all-clear for biodegradable fibres and natural fibres: "Biodegradability alone does not mean that pure natural fibres, for example, are completely harmless to the environment. They, too, remain in ecosystems until they completely degrade and can also have a negative impact. In addition, additives, auxiliaries or finishes used in textile production can further slow the degradation process and leach into the environment."

The new standard enables textile producers and suppliers to test, evaluate and compare products for fibre release during washing and environmental impact. Juliane Alberts sees this systematic evaluation as an opportunity for the textile industry to take the initiative on environmental impact: "Our reliable data can be used as a basis for more targeted product development. This is a way to actively and consciously control further environmental pollution."

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.

Fibre Extrusion Technology Limited (FET) of Leeds, England has installed a FET-200LAB wet spinning system at the University of Manchester which will play a major part in advanced materials research to support sustainable growth and development.

This research programme will be conducted by The Henry Royce Institute, which operates as a hub model at The University of Manchester with spokes at other leading research universities in the UK.

The Henry Royce Institute identifies challenges and stimulates innovation in advanced UK materials research, delivering positive economic and societal impact. In particular, this materials research initiative is focused on supporting and promoting all forms of sustainable growth and development.
These challenges range from biomedical devices through to plastics sustainability and energy-efficient devices; hence supporting key national targets such as the UK’s zero-carbon 2050 target.

FET-200 Series wet spinning systems complement FET’s renowned range of melt spinning equipment. The FET-200LAB is a laboratory scale system, which is especially suitable for the early stages of formulation and process development. It is used for processing new functional textile materials in a variety of solvent and polymer combinations.

In particular, the FET-200LAB will be utilised in trials for a family of fibres made from wood pulp, a sustainable resource rather than the usual fossil fuels. Bio-based polymers are produced from biomass feedstocks such as cellulose and are commonly used in the manufacture of high end apparel. The key to cellulose and other materials like lyocell and viscose is that they can be recycled, treated and fed back into the wet spinning system for repeat manufacture.

Established in 1998, FET is a leading supplier of laboratory and pilot melt spinning systems with installations in over 35 countries and has now successfully processed more than 35 different polymer types in multifilament, monofilament and nonwoven formats.

• Strategic partnership for automation system in the field of slot dies and coextrusion adapters

Reifenhäuser Extrusion Systems (RES) - the Reifenhäuser Group's business unit specializing in extrusion components - announces a strategic partnership with maku AG at K 2022, the world's largest plastics trade fair. The aim of the cooperation is the joint marketing and further development of the automation system designed by maku for coextrusion adapters and slot dies.

The so-called PAM system (precise, autonomous, mechatronic) is available immediately and exclusively as an automation option for new Reifenhäuser dies and adapters, as well as for aftermarket dies across all manufacturers. PAM enables producers in the field of flat film and sheet production as well as extrusion coating to precisely control the entire hot part (coextrusion adapter and die) via the line's control panel. This is significantly faster and more accurate than conventional control by hand or expansion bolt automation. It enables faster start-up of good production, higher output with lower energy consumption, and thus significantly improved overall equipment efficiency (OEE). The decisive advantage lies in the use of motorized manual adjustment bolts that replace conventional thermal expansion bolts. Reifenhäuser presented the system for the first time at the K 2022.

• Carbios’ biorecycling and biodegradation technologies internationally recognized by consumers as promising answers to their top environmental concerns
• Carbios’ innovations considered one of the best for solving recycling effectively and achieving a real plastic circularity
• Consumer research including qualitative and quantitative fields was conducted between March and August 2022. The research institute, Strategic Research, conducted 6000 interviews in Europe and USA

Carbios’ biorecycling and biodegradation technologies acclaimed by consumers
During the first research field study, respondents were exposed to Carbios’ biorecycling process; a new enzyme-based biotechnology that enables biological recycling of all types of PET plastic waste (including bottles, packaging and textiles), and pushes the boundaries of recycling in terms of the number of cycles.

The research results demonstrated that European and US respondents find Carbios’ biorecycling technology more unique and innovative than traditional PET recycling (i.e. thermo-mechanical recycling), as well as more relevant in its ability to address their concerns and challenges regarding recycling.

In the second research study, conducted in the US, respondents were also exposed to Carbios’ biodegradation technology: an innovative enzymatic solution by which an enzyme is incorporated into plastics during the production process of bio-sourced PLA plastics (corn, sugar cane). This approach makes the material made from plants 100% compostable at ambient temperatures and degradable like plants with the built-in enzyme biologically breaking the bioplastic down in less than eight weeks without microplastics or toxic residues; creating a fully organic circularity.

Similarly to Carbios’ biorecycling technology, Carbios’ PLA biodegradation innovation caught US respondents’ attention with 64% overall liking it. Additionally, 93% of the respondents sampled described the concept as innovative, unique, easy to understand (49%), and believable (43%). Up to 82% of the most environmentally engaged respondents declared they would definitely buy more products made with Carbios’ fully circular biodegradable bioplastic.

Consumers: No other choice but to make plastic fully circular
The research says 99% of the respondents consider it important to protect the environment, while plastic pollution is now ranked the third most-concerning environmental issues after climate change and ocean pollution.

This awareness brings most of these consumers to be environmentally active when it comes to purchasing goods and sorting. For the US respondents, eco-friendly packaging comes in the fourth place in terms of purchase drivers for packaged goods and 65% of them declare sorting plastic from general waste on a regular basis, which makes plastic the most sorted type of waste.

Nevertheless, for a vast majority of the respondents across geographies, even if they would like to reduce their plastic consumption most of the time there is no suitable alternative that is as convenient, light, and cost-efficient as plastics. Hence in an ideal world, consumers would like all plastic waste in landfills and oceans to be collected, cleaned, reused and recycled.

Carbios announced the appointment of Pascal Bricout as Chief Strategy and Financial Officer and a member of the Company’s Executive Committee.

Mr. Bricout will oversee the management and organization of Carbios’ Finance division. He will also steer the Group’s Strategy, investor relations and the launch of the company’s Corporate Social Responsibility policy. He joins the company with over 30 years’ experience in finance, strategy and international mergers and acquisitions.
 
Prior to joining Carbios, Mr. Bricout served as Chief Financial Officer for Michelin in Asia, which is a major area of growth and development for the company. Over the past 10 years, he has focused primarily on major strategic mergers and acquisitions.

Mr. Bricout holds a Master Degree in Finance from Université Paris-Dauphine. He began his career at PwC, as a manager in the International Transactions Services teams in Paris and London.

Mr. Bricout, Carbios’ Chief Strategy & Financial Officer noted: “I am thrilled to be joining Carbios and proud to take part in this concrete, meaningful advance toward circular economy. Having developed unparalleled breakthrough technologies in plastic and textile biodegradation and biorecycling, Carbios now needs to execute a successful industrial and commercial phase. This is crucial for companies using PET to achieve, from 2025, their sustainable development goals. Within this dynamic context, Carbios and its subsidiary, Carbiolice, are poised to become global leaders in the development and industrialization of innovative bioprocesses to revolutionize the life cycles of plastics and textiles.”

More than 350 million tons of plastic are produced worldwide every year, and vast amounts of plastic waste simply end up in the environment. The circular economy offers enormous potential for keeping plastics in the loop and thus conserving resources and the environment. Since 2018, six Fraunhofer institutes in the Fraunhofer CCPE cluster have been researching how to make the plastics value chain circular, and Prof. Manfred Renner has been the new head of the cluster since August 2022. Research results, implementation projects and strategies to accelerate the transformation to a circular plastics economy will be presented by Fraunhofer CCPE at the first international Fraunhofer CCPE Summit on February 8 and 9, 2023 in Munich.

In a circular plastics economy, resources can be saved, products can be intelligently designed for long service life, and end-of-life losses can be reduced. Systemic, technical and social innovations are needed to make the transition from a linear to a circular economy a success. This is what the Fraunhofer Cluster of Excellence Circular Plastics Economy CCPE is researching in the three divisions “Materials”, “Systems” and “Business”. The cooperation of the six Fraunhofer institutes IAP, ICT, IML, IVV, LBF and UMSICHT enables a multi-stakeholder approach in which the appropriate R&D competencies are bundled.

Fraunhofer CCPE would like to present and discuss successful projects and research approaches on an international scale at the Fraunhofer CCPE Summit on February 8 and 9, 2023 in Munich. The summit is to become an international forum for exchanging ideas for solutions and innovations for a circular plastics economy.

Cross-industry collaboration - local, regional and international
Since August 2022, Prof. Manfred Renner, Institute Director of Fraunhofer UMSICHT, is the new head of Fraunhofer CCPE. He succeeds Prof. Eckhard Weidner, who has retired. “Cross-industry cooperation - very local, but also regional and international - is the elementary prerequisite for a functioning circular plastics economy. At the summit, players from all points of the compass will meet and network in order to rethink the plastics value chain together," explains Prof. Manfred Renner, adding, “We want to provide answers to the following questions:  How can we make all Circular Economy principles, i.e. the ten R-strategies, known? How can industry, science and society best cooperate in a transformation to a circular plastics economy for the greatest possible impact?”

Results of the Fraunhofer CCPE cluster so far are innovative approaches for circular business models, intelligent collection, sorting, and recycling technologies, but also new formulations for circular polymers and compounds to enable multiple recycling cycles. With the newly developed assessment tool CRL® , companies can, for example, self-assess the maturity of products or product systems with regard to the circular economy. The tool checks the extent to which a product already takes into account circular economy principles in the areas of product design, product service system, end-of-life management and circular economy, and where there is still potential for improvement.

• Monomaterial solution contains renewably-sourced polypropylene from the Bornewables™ portfolio of circular polyolefins
• Trexel employs its proprietary MuCell® technology to deliver a range of lightweighting benefits
• EverMinds™ in action: reuse and design for recycling are focus of value chain collaboration

Borealis and Trexel, an expert in foaming injection and blow moulded parts, announce that they have co-developed a new plastic bottle based on a grade from the Bornewables™ portfolio of polyolefins made using renewable feedstocks derived 100% from waste and residue streams. The lightweight bottle – which will be showcased at the Borealis stand at the K 2022 (from 19 to 26 October 2022 in Düsseldorf) – is reusable and fully recyclable. It boasts a significantly lower overall CO₂ footprint because it is composed of renewably-sourced feedstock and produced in the foaming process.

The Bornewables™ portfolio of circular polyolefins helps reduce the carbon footprint while offering material performance equal to virgin polymers. Using Bornewables grades allows for design freedom and colour flexibility, and helps retain a premium look and feel. The grades – which are commercially available in Europe – help conserve natural resources because they are derived solely from waste and residue streams, for example from used cooking oil. Reusing waste already in circulation instead of fossil fuel-based feedstocks enhances the sustainability of applications made using the Bornewables grades.

The reusable new bottle developed by Borealis and Trexel retains its value over many life cycles thanks to the use of Trexel’s proprietary technology in tandem with Bornewables grades; as a material solution, the new bottle minimises the use of valuable raw materials. Moreover, converters consume less energy in the production process when using the MuCell® technology. The bottle thus helps close the loop on plastics circularity by way of design for recycling, the use of renewable feedstocks, and excellent material performance across multiple life cycles.
