From the Sector

Freudenberg Performance Materials – the Freudenberg Group’s nonwovens specialist – was hosting a meeting of the German National Hydrogen Council at the Freudenberg headquarters in Weinheim, Germany, on September 16. As a leading global supplier of technical textiles, Freudenberg Performance Materials provides fuel cell components for mobility applications and for electrolyzers used to produce CO₂-free hydrogen.

The German National Hydrogen Council was appointed by the German government and acts as an independent, non-partisan advisory board. The council board currently consists of 25 high-ranking experts in the fields of economy, science and civil society. The objective is to assist and advise the State Secretaries’ Committee on Hydrogen in the further development and implementation of Germany’s National Hydrogen Strategy. Council meetings are hosted by one of the board members to enable the council to deepen its knowledge of the relevant technologies, value chain roles and challenges. Dr. Silke Wagener is a member of the council board, and represents the Freudenberg technology group, giving input on suppliers’ know-how as well as contributing her decades-long expertise in technological solutions for the hydrogen industry.

During a tour of the factory organized for the council board members, Freudenberg Performance Materials explained the development and production of performance-critical gas diffusion layers manufactured from carbon fiber-based nonwovens for fuel cells and porous transport layers for electrolyzers. The tour highlighted the potential for improvements from a supplier’s perspective, such as the need for very timely exchange and collaboration along the value chain. Functioning, unbroken and scalable value chains, in parallel with the development and scaling of hydrogen infrastructure, are key prerequisites for the hydrogen industry to fulfill its vital role in the transformation to climate neutrality.

Gas diffusion layers are one of the main components at the heart of the fuel cell. Their function is to transport gases and liquids in the cells. They have a significant impact on system performance and costs, and are indispensable for the functioning of fuel cells. The same applies for porous transport layers that are the key component of electrolyzers for the CO₂-free production of what is called green hydrogen.

Fuel cells in combination with green hydrogen are an important technology for CO₂-free mobility, in particular with reference to buses, heavy-duty trucks and trains. Other uses include stationary applications such as stationary power generation or heat generation in buildings or industry.
Apart from mobility, green hydrogen also plays a key role in climate-neutral energy supplies in the industrial sector, particularly in the chemical and steel industries.

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.

• Partnership with green power producer Enery and Energie Steiermark realizes construction of a photovoltaic plant with 5.5 MWpeak capacity
• Strategic investments in renewables boost energy independence and reduce carbon footprint

The Lenzing Group has signed an electricity supply contract with green power producer Enery and Energie Steiermark to finance a photovoltaic plant in the Deutschlandsberg region (Styria). The electricity generated will supply the fiber and pulp plant at the Lenzing site after commissioning from the fourth quarter of 2023. The electricity supply contract is limited to 20 years.

The plant’s output will amount to 5.5 MWpeak. This corresponds to the average annual electricity demand of more than 1,700 households. Several photovoltaic systems are already being installed at the Lenzing site, including the largest ground-mounted plant in the province of Upper Austria, whose commissioning is imminent.

In 2019, Lenzing became the first fiber manufacturer to set a target to reduce its carbon emissions by 50 percent by 2030 and to be climate neutral by 2050. This carbon reduction target has been confirmed by the Science Based Targets Initiative. Lenzing is also currently investing in reducing carbon emissions at other sites worldwide. Only recently, the Lenzing Group announced that its Indonesian site will also be relying on green energy in the future.

adidas has unveiled the latest in its Made with Nature Capsule Collection with a new Ultraboost 22 Made with Nature and Made with Nature apparel joining the range as the brand continues its mission to call time on conventional materials and design out finite resources.

Designed in balance with the planet, the women’s Ultraboost 22 Made with Nature takes the forward-thinking elements of the Ultraboost 22 and amplifies them with natural materials. The shoe is made in part with natural materials – 40% of the knitted upper is made with lyocell, a material created with cellulosic fibers made from sustainably grown wood.

Launching alongside the Ultraboost 22 Made with Nature is a new Made with Nature apparel range, including a performance running wear look for men and women. The apparel range is made with at least 50% organic cotton.

Christopher Wheat, Global Category Director Running Footwear said: “At adidas, we understand that change is not only possible, it’s an urgent necessity. With Made with Nature, we are on a journey to a world beyond plastic. We’re calling time on conventional materials and methods of make. Once depleted, there’s no coming back for fossil resources. But when we design in synergy with natural processes, when we make with nature, we can use materials that regrow or regenerate – and change the way products are made."

A new fabric inspection technique for accurately detecting the most subtle of defects on patterned fabrics during high speed production has been developed by BTMA member Shelton Vision, of Leicester, UK.

The patent-pending system has been integrated into the company’s WebSpector platform and validated through factory trials on a purpose-built full scale in-house demonstration system with sophisticated fabric transport capabilities. As a result, a first system has already been ordered by a manufacturer of both plain and patterned fabrics, including camouflage, in Colombia. This follows the successful conclusion of a 21-month Innovate UK project in which techniques for the resolution of complex pattern deformations were developed by machine vision and computer scientists in the company, backed up by the machine vision and robotics department at Loughborough University.

Restrictions
Traditional methods for defect detection rely on human inspection which is ineffective, with detection rates under 65%, while the Shelton WebSpector machine vision system offers a sophisticated platform for automated defect detection of over 97%, but until now has been restricted to plain textiles.

While pattern matching and neural network approaches have previously been tried for patterned textiles, they have failed to provide a practical solution due to the extreme complexity associated with pattern matching on deformable substrates like textiles, as well as the time required to train a neural network for each pattern type.

Challenges
The challenge is that fabrics are not rigid and can be creased or stretched and are also subject to local distortion,” says Shelton Vision Managing Director and CEO Mark Shelton. “As a result, inspection without the technique we have developed, would lead to thousands of false positives. Our sophisticated pattern inspection software techniques ensure a clean image, allowing the detection of faults on fabrics running at speeds of up to a hundred metres a minute.”

The full system consists of:

• A camera and lighting system for optimum image capture at high speed and associated image processing hardware.
• Self-training software utilising statistical analysis to automate the system configuration for new textile products.
• An advanced suite of defect detection algorithms for the detection of all textile defect types.
• An AI-driven defect classification system which learns and automates defect naming in real time, as well as a real time defect grading capability based on client decision rules.
• A system for recording and retrieving complete roll map images for subsequent review and quality control.

The generation of textile roll maps with complete defect data allows for an optimised textile cut plan, improved downstream processing and quality assurance.

• 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.
