From the Sector

Stahl announces that its near-term greenhouse gas (GHG) emissions reduction targets have been validated by the Science Based Targets initiative (SBTi). Stahl is one of the few coatings companies to receive this validation. To date, 145 companies in the chemicals sector have submitted an emissions reduction target to the SBTi, of which 61 have had their targets validated.

Stahl’s science-based targets, which reflect the company’s commitment to the 2015 Paris Agreement goals, are:  

• Stahl Holdings B.V. commits to reduce absolute scope 1 & 2 GHG emissions 42.0% by CY2030 from a CY2021 base year.*
• Stahl Holdings B.V. commits to reduce absolute scope 3 GHG emissions 25.0% by CY2030 from a CY2021 base year.

The SBTi classifies emissions reduction targets according to two potential temperature pathways: 1) limiting global temperature rises to 1.5°C above pre-industrial levels, and 2) limiting temperature rises to well below 2°C. The SBTi has determined that Stahl’s Scope 1 and 2 target is in line with a 1.5°C trajectory, while Stahl’s Scope 3 target has been validated in line with the well-below 2°C pathway.

Maarten Heijbroek, CEO of Stahl: “The validation of our Scope 1, 2, and 3 emissions reduction targets by the SBTi is an important milestone on our ESG journey as we strive to limit our contribution to global warming, in line with the Paris Agreement. Our targets are ambitious, and rightly so. Realizing our goal to help create a more responsible coatings value chain starts with being accountable for our own environmental impact, and taking concrete steps to reduce our emissions wherever possible.”

A clear strategy to reduce GHG emissions
Stahl’s approach to realizing its near-term emissions reduction targets is outlined in the company’s Environmental, Social, and Governance (ESG) Roadmap to 2030. This strategy defines the specific metrics against which progress on the company’s ESG commitments will be measured.

Stahl’s Scope 1 and 2 GHG emissions reduction targets, as submitted to the SBTi, cover emissions from all manufacturing sites where Stahl products are produced, as well as the company’s largest non-manufacturing locations. Stahl aims to lower these emissions by reducing its overall energy consumption and increasing the use of renewable energy at its sites. To achieve this, the company plans to increase its self-generated electricity capacity (using solar power, for example) and continue investing in more energy-efficient equipment.

Stahl plans to reduce its Scope 3 upstream emissions primarily by replacing fossil-based raw materials in its products with renewable alternatives, such as bio-based and recycled-based feedstocks. In addition, the company plans to introduce more low-impact raw materials into its product design.

* The target boundary includes biogenic land-related emissions and removals from bioenergy feedstocks.

adidas has announced a new milestone in its journey towards replacing virgin polyester with recycled polyester . 96% of all polyester used in adidas products is now recycled polyester. The achievement of the ambition that adidas first set in 2017 – to replace all virgin polyester with recycled wherever possible by the end of 2024 – is on track to be achieved earlier than expected.

Since the first adidas high-performance shoe was made with recycled materials in 2015, the brand has been working towards reducing its dependency on virgin polyester. Last year it announced that in 2021, more than 90% of the polyester used in adidas products was recycled, which – if it had been virgin polyester - would have accounted for 390 thousand metric tons of CO₂e – the equivalent to the greenhouse gas emissions generated to provide power to 50 thousand homes in the US^[1].

According to Textile Exchange^[2], global recycled polyester fiber production volume increased in 2021, but still accounts for just 14.8% of all global polyester production.

Sport is about meeting challenges head-on and finding ways to overcome those – material innovation is no different. For the team at adidas, the road to 96% has been long and full of challenges. The confirmation of its polyester commitment in 2017 was a crucial step in helping to initiate a transformation across adidas and its entire supply chain. This transformation has been made possible through creating technical solutions and imagining new possibilities that previously didn’t exist.

To accompany the announcement, adidas has created a short film about its new ‘PB’, featuring star athlete Jazmin Sawyers. The film highlights the sports brand’s pride in making progress, and its determination to push further.

As the brand looks ahead to 2024 and beyond, it will continue to expand its focus beyond recycled polyester. It will be doing this through three main areas of focus: changing materials by testing and scaling new raw materials, rethinking entire processes to design products that have a circular end-of-life solution, and reducing its carbon footprint.

Yanfeng has reached another milestone in its sustainability journey by bringing the power of solar energy to its plants in South Africa. The global automotive supplier already uses renewable energy at all its locations in Europe – some of which are already operating with 100% green energy – and now will supplement its operations in South Africa with sustainable and emission-free solar energy generation.

Many sectors are facing major challenges with the transition to a low-carbon economy. The automotive sector in particular faces many operational and economic challenges when transforming production plants into net-zero emission operations. Thanks to its commitment to sustainability, 100% of the solar energy generated by the PV systems is used to power Yanfeng’s production plants in South Africa, helping them save around 2,559 tons of CO2 annually while reducing their monthly costs and increasing efficiencies.

The solar energy systems were funded by SolarAfrica, which will also operate, maintain and monitor the systems going forward. “From the outset of these projects, Yanfeng’s focus was on reducing their CO2 emissions and SolarAfrica is proud to partner with them to make their journey towards sustainability a success,” said David McDonald, CEO of SolarAfrica. “It’s inspiring to see a global company like Yanfeng invest in world-class facilities in South Africa, contributing to our country’s green economy and supporting job creation in the automotive industry.”
 
All Yanfeng European plants were converted to renewable energy by the beginning of 2022. With this new PV system, Yanfeng has implemented a milestone in the conversion to net-zero emission production at its two plants in South Africa.

• Iconic 200 Series fleece to be the first fabric made from this new process.

Polartec®, a Milliken & Company brand, announces Polartec® Shed Less Fleece, a new milestone in its industry-leading efforts to reduce textile fiber fragment shedding. Shed Less is a process that combines yarn construction, knitting, chemistry, and manufacturing to reduce home laundry fiber fragment shedding by an average of 85%. The first fabric to receive this new technology is the brand’s iconic Polartec® 200 Series Fleece, the modern version of the original PolarFleece® launched in 1981, and in 1993, the first performance fleece knit from yarn made from recycled plastic bottles.

The Shed Less process works by engineering the lofted fibers that give fleece its soft hand the ability to resist breaking and rubbing off during home laundering, cited as one contributing factor to the spread of fibers fragments (commonly referred to as microfibers). Polartec® Shed Less Fleece achieves this while maintaining all of the attributes that continue to make Polartec fleece a staple of midlayer collections - lightweight, breathable and warm.

The brand used the AATCC (American Association of Textile Chemists and Colorists) TM212-2021 test method for fiber fragment release during home laundering. This test was conducted with large sample sizes to account for variability. The testing concluded that Shed Less Fleece reduced fiber fragment shedding by an average of 85% compared to the baseline fabric.

“In 2016 we began looking into how we might test for fiber loss because there wasn’t a lot of research on the issue.” said Aimee LaValley, Polartec Textile Development, Dye and Chemistry Manager. “This led to new products like Polartec Power Air™, new manufacturing processes, as well as our participation in the TextileMission workgroup to study the issue on an interdisciplinary basis.”

TextileMission was a three year collaborative initiative of academia and industry to reduce the impact of textile microplastics funded by the German Federal Ministry of Education and Research. Founding partners include The Association of the German Sporting Goods Industry, Hochschule Niederrhein - University of Applied Science; TU Dresden - Institute of Water Chemistry; Vaude Sport; WWF Germany; Adidas AG; Henkel AG; Miele & CIE; and Polartec, LLC.

Polartec® Shed Less Fleece will be initially launched in the United States and will be available to customers beginning March 1, 2023. The brand plans to apply the Shed Less process to many other industry-leading fabric platforms and manufacturing facilities around the world.

• adidas unveils its SS23 Melbourne Tennis Collection – an apparel range fit for performance
• Inspired by plants and florals, the collection features bold prints, vibrant colorways and a moiré effect textile
• The adidas SS23 Melbourne Tennis Collection will be available from Jan 13 2023

adidas launches its new SS23 Melbourne Tennis Collection, a range of performance apparel featuring striking colorful prints, inspired by plant life and nature. Select pieces feature a contrast-color mesh layering that when in motion creates a moiré effect and helps to mask the player’s movements and positioning on court.

With the help of innovation, adidas is seeing possibilities in turning towards new resources. For these products adidas turned to a greenhouse gas technology. It uses captured industrial emissions as a new material feedstock. CO₂ is fermented into ethanol which constitutes 30% by weight of a polyester yarn. adidas knitted this yarn into various products and now this carbon-based ethanol makes up a minimum of 15% by weight of these garments.

In addition, the collection also utilizes HEAT.RDY and Aeroready technologies. HEAT.RDY technology is designed to maximize airflow and optimize sweat distribution, while AEROREADY is powered by moisture-wicking fabric that absorbs sweat quickly for a dry feeling, helping players to move freely and comfortably on court.

The SS23 Melbourne Tennis Collection will be premiered on court by adidas athletes, including Stefanos Tsitsipas, Felix Auger Aliassime, Garbiñe Muguruza, Qiang Wang and Maria Sakkari.

The SS23 Melbourne Tennis Collection will be available from Jan 13.

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.

A new cold chamber at its headquarters in Winterthur, Switzerland, enables Autoneum to optimize existing technologies as well as simulation and engineering services in vehicle thermal management and to adapt them to the changing thermal requirements of electric vehicles

The absence of heat from the internal combustion engine in electric vehicles as well as the impact of ambient temperature on the performance and lifetime of lithium-ion batteries are changing the requirements for vehicle thermal management. In addition, the energy from the battery is used not only to power the e-motor but also to thermally manage the battery itself and to warm and cool the car cabin by means of the heating, ventilation and air conditioning system. To increase the thermal comfort of the occupants and at the same time ensure optimum battery performance, save energy and thus increase the car’s range, manufacturers are placing increasing emphasis on efficient overall thermal management of the vehicle.

The chamber enables to test both occupants’ subjective perception of thermal comfort and the performance of components and entire vehicles under controlled temperature conditions of up to minus 20 degrees Celsius. It is thus a valuable addition to the existing testing and bench-marking facilities at the Company’s global research and development centers. The tests conducted in the chamber show how existing insulating components such as under battery shields, carpets and interior trim need to be optimized to further enhance the thermal management of the vehicle battery and cabin. The tests also provide valuable insights regarding the development and optimization of heated surfaces such as floor mats and door trim panels to improve thermal performance and driver comfort of electric vehicles.
