From the Sector

Lenzing Group, a global producer of wood-based specialty fibers, is celebrating the 40th anniversary of its biorefinery and co-product brand LENZING™ Acetic Acid Biobased. The brand was first introduced on May 4, 1983, and has since become one of the leading and most trusted biobased acetic acid providers.

Over the past 40 years, LENZING™ Acetic Acid Biobased, which has a reduced carbon footprint that is 85% lower than that of fossil-based acetic acid, has continued to gain trust and support from customers. Specialty chemical company Evonik, and food production company Speyer & Grund Group, have been incorporating LENZING™ Acetic Acid Biobased in the production of their products since 1983. LENZING™ Acetic Acid Biobased has also been in high demand from the hygiene industry during the COVID-19 pandemic as an all-purpose cleaning agent in conventional and green products.

Pioneering a carbon neutral future in the biorefinery segment with a new offering
To mark the important occasion, Lenzing will introduce its first carbon neutral LENZING™ Acetic Acid Biobased to meet the growing sustainability needs of industries which predominately rely on fossil-based materials. Similar to the standard LENZING™ Acetic Acid Biobased, the carbon neutral LENZING™ Acetic Acid Biobased is produced using sustainably sourced beech wood as a universal replacement for non-renewable raw materials such as crude oil. By calculating, reducing and offsetting emissions during production processes, this expansion will create a more sustainable supply chain with highly functional products across various industries. From now on, Lenzing customers across the food, pharmaceutical, cosmetics, chemical and textile industries will be able to choose between carbon neutral and reduced carbon footprint acetic acid products.

Advancing circularity and carbon neutrality through efficient use of valuable resources
Lenzing’s biorefinery concept ensures that 100% of wood components are used to produce pulp for Lenzing’s botanic fibers, biorefinery products, as well as bioenergy, which is used to power Lenzing’s facilities. This makes Lenzing’s biorefinery sites almost fully energy self-sufficient to remain as carbon neutral as possible. To ensure a low carbon footprint, rail transportation is the preferred means for transporting LENZING™ biorefinery products, with trucks being leveraged in regions where rail transportation is not available.

Together with ClimatePartner, a recognized global leader in the design, development, and delivery of corporate climate action programs, Lenzing strives to reduce carbon emissions to net-zero through a mix of higher production efficiencies, use of renewable energy sources, low-carbon materials, and the dedicated support of an external nature-based carbon removal project. For instance, to offset remaining carbon emissions that cannot be reduced, Lenzing works with ClimatePartner to support and finance the switch to biomass as an energy source at a ceramic factory in Kitambar in northeastern Brazil. Using natural waste materials, like coconut shells, as renewable biomass for its energy production, the factory is able to produce roof tiles in a more climate-friendly way while saving on carbon emissions. Besides contributing to the fuel switch, the project also helps to reduce the deforestation rate in Brazil and avoid methane emissions that could result from the uncontrolled rotting of biomass.

"Policy makers need to consider that global dimension."
 
EURATEX released its 2023 Spring Report, which analyses latest trade flows for textiles and clothing products.

In 2022, EU trade in textiles and clothing has exceeded, for the first time in history, the €200 billion mark. This record growth of total trade is mainly due to a sharp increase of clothing imports (+36,6% in value), especially from China and Bangladesh, which outweighs Europe’s positive export performance. As a result, the EU’s trade deficit in textiles and clothing has increased to €70 billion, which is 48% higher than the year before.

Such a growing deficit is a cause for concern; the objective of the EU’s Industrial Strategy to strengthen resilience and “strategic autonomy” is not happening. Instead, the dependency has increased, and becomes critical in certain raw materials and fibres.

It also challenges the Commission’s ambition is to promote – and prevail – high quality and sustainable textile products on the Single Market – regardless where they have been produced. With imports now reaching €140 billion, it will be a challenge to effectively control the quality and compliance over these imports. Market surveillance will need to be stepped up massively, without becoming a barrier to trade.

The efforts on the EU’s export performance need to be strengthened, so as to rebalance the European trade relations with the rest of the world. EU companies are world leader in high end fashion products and in technical textiles. More needs to be done to support their activities in established markets but also emerging economies. For instance, the ongoing FTA negotiations with India should focus on improving market access and ensure “fair” competition with local companies.

The EURATEX Spring Report highlights significant differences between trade in value and in volume. EU’s export of textile products has increased by 13% in value, but actually dropped by nearly 7% in volume. This obviously reflects the very high inflation figures from last year, caused initially by the rising energy prices and changing central bank policies. This in turn leads to uncertainty with the consumer, resulting in low demand and gloomy prospects for the entire value chain.

Director General Dirk Vantyghem commented on these latest figures: “This report confirms once again that “textiles” is one of the most globalised sectors of the European economy, and hence the importance of taking that global dimension into account, when designing EU and national policies. Failing to do so may have a devastating effect on the global competitiveness of the European textile industry.

Looking forward, he added: “It is essential to stabilise inflation, restore consumer confidence and ensure a level playing field for all operators in the textile industry. On that basis, European companies can prosper and offer quality jobs to 1.3 million workers”.

Since 1 April 2023 sales and service of Mayer & Cie. circular knitting machines in Bangladesh have been under new management. A new dynamic team “Mayer Bangladesh” has been formed. Mayer & Cie.’s longstanding Indian representative Batliboi has joined business activities in Bangladesh since the beginning of the month, supported by the team of Brady Services and by Almani Biz.

In Batliboi, Mayer & Cie. has set up a business partner of many decades standing as its representative in Bangladesh. For around 40 years Mumbai-based Batliboi has overseen sales and service of Mayer & Cie. circular knitting machines in India. Abhay Sidham heads Batliboi’s Textile and Machinery Group. He and his team have many years of experience in strategic marketing, and a focus on sustainability and processing recycled raw materials is part of Batliboi’s expertise.

These competences are of relevance in the Bangladesh market because “we face strong competition from Asian manufacturers here,” as Wolfgang Müller, Mayer & Cie.’s sales director, explains. The premium market was growing smaller, and the trend was toward specialities – value-added fabrics, spacer fabrics and athleisure with a high proportion of elastic. Mayer & Cie. sees in these requirements significant potential for its machines – and in Batliboi a partner able in view of its experience to put them to optimal use.

One building block in the set-up of Mayer & Cie. representatives is unchanged. Brady Services will continue with Batliboi to contribute its close ties with the local market. A significant number of existing companies will continue to be looked after by Brady Services.

The new member in Mayer Bangladesh team is Dhaka-based Almani Biz. A lubricants specialist for circular knitting machines Almani Biz has a wide network with Bangladesh knitting industry.

Mayer & Cie. feels well positioned by this new set-up. “We,” Wolfgang Müller says, “are of the opinion that the market for textile machinery in Bangladesh will continue to grow and we are confident that by strengthening our sales, service and marketing team we will be able to make good use of this opportunity.”

Customers in Bangladesh have placed large orders in the past. The latest, placed in January, was for several dozen machines to be delivered this autumn. Further orders from Apex and BEXIMCO (Bangladesh Export Import Company) are also scheduled for delivery in the second half of 2023.

While reorganising the set-up of its representatives in Bangladesh Batliboi has also taken over as Mayer & Cie.’s representative in Nepal, where the company had previously had no local representative. There is a demand for machines for interlock, 8-lock and single jersey, but sales are still in single figures.

A little over three years have passed since RadiciGroup announced the acquisition of Zeta Polimeri, an Italian company headquartered in Buronzo (VC) with over 30 years' experience in the recovery of pre- and post-consumer synthetic fibres and thermoplastic materials. Today, the company has become a full member of the Group with its new name Radici EcoMaterials Srl.

The new company’s long-standing know-how, combined with RadiciGroup’s as a whole, will create a virtuous production system that recovers worn-out materials (fabric, yarn and granules), or otherwise unusable materials, and processes them into raw materials available for other production cycles by taking advantage of industrial synergy.

Radici EcoMaterials is a strategic production site because it handles all the preliminary recovery stages: the sorting, processing and pre-treatment of materials, including those used for the production of post-consumer yarns and engineering polymers. In this sense, Radici EcoMaterials is in line with the most recent European policies on sustainable textiles, which address minimizing the share of materials destined for disposal sites, favouring instead more structured recycling solutions.

Radici EcoMaterials is also GRS certified. GRS certification ensures the complete traceability of its materials, which are made in a safe plant that meets the highest environmental and social certification standards.

The company is also equipped with a photovoltaic system and, for the portion of its energy needs not covered by the photovoltaic source, it partially relies on renewable energy. The goal is to use 100% green energy in the next few years, in accord with RadiciGroup's goals.

Textile waste is a problem in Europe. Out of 7-7.5 million tonnes of textiles discarded every year, 30-35 % are collected separately – and of that quantity, 15-20 % are sorted by medium and larger sorting facilities within the EU. After sorting, 60 % still qualify as wearable clothes, however after a second or third collection-loop, all of the textiles become non-wearable sooner or later. Therefore, fibre-to-fibre recycling is becoming increasingly important to preserve the valuable resources.
 
The textile recycling value chain is not yet mature, but we are on the verge of a turning point, as different fibre-recycling technologies are deployed on a large scale. If successful, the textile recycling industry could reach a recycling rate of 18 to 26 percent of gross textile waste in 2030. This would create economic, social and environmental value that could total 3.5 to 4.5 billion euros in 2030.

Today, there is a sorting gap to achieve a circular economy for textiles in Europe. To feed this new circular value chain, a significant sorting-capacity increase is needed with 150 to 250 sorting and recycling facilities nearby, as the McKinsey-study “turning waste into value” assessed.

There is also a technology and capacity gap in sorting for reuse and recycling to ensure that high quality raw materials from non-wearable textile waste can be made available on a large scale. This is why the “Transform Textile Waste into Feedstock” project was initiated by TEXAID, within the ReHubs initiative together with well-known stakeholders of the textile value chain.

The major outcome of this project will be a sorting-factory blueprint fulfilling the requirements to the future needs of fibre-to-fibre recycling, enabling the future of more sustainable textiles by using recycled fibres. TEXAID, who is leading the project, is committed to build and operate scalable sorting facilities across Europe, the first with a capacity of 50,000 tonnes by the end of 2024.

Companies like Concordia, CuRe Technology, Decathlon, Inditex, Indorama Ventures, L’Atelier des Matières, Lenzing, Marchi & Fildi, PurFi, Södra, Worn Again and others are taking part in the project to jointly evaluate technologies and the business case for scaled sorting for reuse and recycling. ITA Academy GmbH (in cooperation with RWTH Aachen) together with CETIA has been commissioned for the assessment of technologies. The outcome will be an innovative sorting system 4.0, building on cross-functional technologies with digitalization and automation are at the heart.

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.

Over the past three years, a dedicated AI development team at BTMA member Shelton Vision has been developing tailored machine learning solutions for the textiles industry.

The aim has been to elevate the detection process and the accuracy of naming and grading subtle defects in textiles, in real time within production environments.

“Big Data ‘off-the-shelf’ systems such as those behind technolgies like facial recognition and Google Maps involve reading many thousands of single images each second and simply take too long to accumulate sufficient data for what’s required in this specific case,” says Shelton Vision CEO and Managing Director Mark Shelton. “A feature of the textile industry is that in many sectors, the product range changes several times within a year and it is not uncommon to have to inspect hundreds, if not thousands of different styles in a year based on precise settings.”

In terms of defect types, he adds, there may typically be over 100 that need to be accurately detected, classified (named) and graded in real time.

“Added to this is the need to ‘filter out’ the random occurrence of ‘non defects’, such as loose threads, lint and dust on the surface – the number of which can be higher than actual defects – and it is clear that a bespoke system is required.”
The development team has consequently established metadata for identifying defect properties, enabling the successful identification of faults from a much smaller number of images.

“The system employs a unique combination of machine learning for automated style training and novel algorithms for defect detection, to provide high quality images for the AI real time defect classification and grading software,” Shelton explains. “Due to the inherent variation in fabric features – raw materials, construction, texture, colour and finishes, as well as the differing product quality standards in value chains and the regional variations in what defects are called – our AI engine uses models built for each individual company or group of companies, or product value chain.”

The AI models are constructed so that the user operatives can populate them with their own data produced by the vision system or by obtaining defect images from another imaging source (eg a mobile phone camera).  

The occurrence of defects is sporadic and many defect types occur infrequently, although when they do, they can have severe consequences. These scenarios re-enforce the need for the AI engine to be quickly set up and able to operate accurately with limited data sets of typically between 30 and 50 good quality images per defect type.

A further feature is a tool enabling the user to periodically ‘clean up’ the AI data during the set up phase. This is used to resolve conflicting data and to correct mis-named images.

Generally, the highest cost component of fabric production is the raw material and in addition to finished product inspection, a cost effective use for vision systems is in process operation.

Generally, the highest cost component of fabric production is the raw material and in addition to finished product inspection, a cost effective use for vision systems is in process operation.

“There is a need for the real time detection of defects that are being created in separate processes, such as printing or coating and for real time automated systems that can accurately determine the defects and their severity and provide a reliable signal for an operative to rectify the issue, This can result in considerable savings.

Prior to Shelton introducing powerful customised machine vision and real time defect classification, the only systems available were those that required manual sifting through vast numbers of images, which included both real defects and ‘non defect’ images. The task was very often overwhelming and did not provide much benefit beyond manual fabric inspection.

Perstorp has been acquired by PETRONAS Chemicals Group Berhad (PCG), Malaysia´s leading integrated chemicals provider and part of PETRONAS Group, on 11 October 2022.

In May this year, PCG signed a Securities Purchase Agreement with Financière Forêt S.à.r.l, a company under PAI Partners, a European private equity firm, to acquire the entire equity interest in Perstorp, a leading sustainability-driven global specialty chemicals company based in Sweden. With the completion of the acquisition, Perstorp is now PCG’s wholly-owned subsidiary.

PCG will strive to ensure the timely completion of Perstorp’s growth projects in a safe and cost-effective manner. Perstorp has several projects lined up in the near future, including the launch of Project Air which aims to reduce carbon emissions through the production of sustainable methanol. Recently, The European Union Innovation Fund selected Project Air, as one of the 17 large-scale green tech projects, which together will be granted more than EUR 1.8 billion. Project Air is a gamechanger for the chemical industry, moving from fossil raw materials to recycled and bio-based feedstock, thereby enabling sustainable chemical products to a large variety of industries and end products. At full capacity, it will reduce global CO2 emissions with close to 500,000 metric tons per year from today’s levels, corresponding to one percent of current emissions in Sweden.

Stahl, an active proponent of responsible chemistry, has been awarded the highest EcoVadis Platinum rating, placing it within the top 1% of companies assessed by EcoVadis. The award underlines Stahl’s commitment to collaborating with its partners to reduce its environmental impact and build a more responsible and transparent supply chain.

EcoVadis is a globally recognized evidence-based assessment platform that reviews the performance of more than 90,000 organizations across key sustainability criteria. These include environmental impact, labor and human rights standards, ethics, and sustainable procurement practices. The latest report from EcoVadis highlights Stahl’s positive progress across all these areas and builds on the Gold rating achieved by the company in 2021. Stahl’s 2030 target is to maintain the EcoVadis Platinum rating by working closely with its value-chain partners to help them reduce their environmental impact – including by supporting their transition to renewable feedstocks. In 2021, 80% of Stahl’s total spend on raw materials was supplied by EcoVadis-rated suppliers.
 
The new EcoVadis rating comes as Stahl accelerates its efforts to ensure a more responsible and transparent supply chain. Recent steps toward this goal have included establishing a dedicated Supply Chain Transparency division within the company’s Environmental, social, and governance (ESG) department. The division will be tasked with coordinating a new product development framework that prioritizes the responsible sourcing of raw materials. Furthermore, in July 2022, Stahl submitted a new greenhouse gas (GHG) emissions reduction target, including a specific commitment regarding the company’s Scope 3 upstream emissions. Stahl aims to reduce these by at least 25% over the next 10 years, compared with the base year (2021). Stahl expects to achieve this reduction primarily by working with its suppliers to replace fossil-based raw materials with lower-carbon alternatives.

• Aims to tackle the immense textile waste generated in urban environments, on the back of import bans of waste materials
• Addresses the shortcomings of current textile recycling technologies, which are unsuitable for urban settings due to the use of heavy chemicals
• Technologies developed by the newly-formed RGE-NTU Sustainable Textile Research Centre will be test-bedded in RGE’s pilot urban-fit textile recycling plant, projected for completion as early as 2024

Royal Golden Eagle (“RGE”), a global group of resource-based manufacturing companies, which includes a world-leading viscose fibre producers Sateri and Asia Pacific Rayon (APR), is developing urban-fit, closed-loop textile-to-textile recycling solutions, through the newly-formed RGE-NTU Sustainable Textile Research Centre (RGE-NTU SusTex). This is a five-year research collaboration between RGE and Nanyang Technological University, Singapore (“NTU”), to accelerate innovation in textile recycling that can be deployed in urban settings. The research centre will develop new technologies to recycle textile waste into fibre and create new, next-generation eco-friendly and sustainable textiles.

This move comes on the back of the tightening of waste import bans in countries such as China, India and Indonesia, which are among the world’s largest waste processors. The stricter import bans have left cities in need of viable local textile recycling solutions to tackle the immense textile waste generated.

RGE Executive Director, Mr Perry Lim, said, “Current textile recycling technologies, which rely primarily on a bleaching and separation process using heavy chemicals, cannot be implemented due to environmental laws. At the same time, there is an urgent need to keep textiles out of the brimming landfills.” He added, “As the world’s largest viscose producer, we aim to catalyse closed-loop, textile-to-textile recycling by developing optimal urban-fit solutions that can bring the world closer to a circular textile economy.”

Globally, an estimated 90 million tonnes of textile waste is generated and disposed of every year, with less than 1% being upcycled into new clothing or other textile materials. By 2030, the amount of global textile waste, which currently accounts for almost 10% of municipal solid waste, is expected to reach more than 134 million tonnes. The textile industry is also responsible for 10% of global greenhouse gas emissions – more than international flights and maritime shipping combined.

At present, most of the available textile recycling technologies are open-loop, where textile waste is typically downcycled to lower-quality products (insulating materials, cleaning cloths, etc.) or be used in waste-to-heat recycling.

“Closed-loop textile-to-textile recycling processes, particularly chemical recycling, are still under development. Scaling up the technologies to industrial scale remains a challenge. A key bottleneck is that refabricating textile waste into fibre needs purity standards for feedstock. However, most of the clothes that we wear are made of a mixture of different synthetic and natural fibres, which makes separating the complex blends of materials challenging for effective recycling.

“Our aim is to address this industry pain point by developing viable solutions that use less energy, fewer chemicals and produces harmless and less effluents, and then potentially scale up across our global operations,” Mr Lim said.

To tackle the key challenges in closed-loop textile recycling, RGE-NTU SusTex is looking into four key research areas, namely cleaner and more energy efficient methods of recycling into new raw materials, automated sorting of textile waste, eco-friendly dye removal, and development of a new class of sustainable textiles that is durable for wear and, at the same time, lends itself to easier recycling.

Technologies developed by RGE-NTU SusTex will be test bedded at RGE’s pilot urban-fit textile recycling plant in Singapore, which is projected for completion as early as 2024. If successful, RGE has plans to replicate the plant in other urban cities within its footprint.
