From the Sector

Stahl has published its 2023 Environmental, Social and Governance (ESG) Report. The report outlines Stahl's recent progress on its ESG Roadmap to 2030 and the steps the company is taking to live its purpose of Touching lives, for a better world.

Stahl’s ESG Roadmap to 2030 includes interim targets for 2023, making this a year in which Stahl reached several important milestones. For example, the company reduced its scope 1 and 2 greenhouse gas (GHG) emissions by 22% versus 2022. Furthermore, in 2023 the Science Based Targets initiative (SBTi) validated Stahl's scope 1, 2 and 3 targets, making it one of the first coatings companies on the SBTi-approved list.

To reduce its GHG emissions, Stahl is actively increasing its use of clean energy. At the end of 2023, renewable energy generation, such as solar panels, had been installed at four Stahl sites, compared to its target of three.

Measuring – and reducing – the impact of products is an important step in the company’s scope 3 emissions. As such, 353 Stahl products now have either life cycle assessment (LCA) or product carbon footprint (PCF) data, far exceeding the 2023 target of 50.
 
New ratings and certifications
In 2023, 2,161 of Stahl's products were certified by Zero Discharge of Hazardous Chemicals (ZDHC), in line with ZDHC MRSL V3.1. These products represented 70% of the company’s sales revenue, demonstrating increased demand for coatings with a lower risk to health and the environment.

Stahl was also proud to achieve a Platinum rating from EcoVadis for the second year in a row, which places it in the top 1% of companies evaluated. Stahl also exceeded its 2023 target of an average EcoVadis rating of at least 60/100 for their top ten suppliers, with an average rating of 68/100 reported in December 2023.
Fostering a safe and welcoming work environment

A core pillar of Stahl’s ESG approach is how it supports its employees’ physical and mental well-being. The 2023 ESG Report outlines several examples of this commitment, such as improvement in its key safety KPIs for the third year in a row.

Besides keeping people safe, Stahl continues to make progress in fostering an open and inclusive workplace. For example, in support of diversity, equity and inclusion (DEI), Stahl appointed its first female leadership team member, trained 98% of its staff in DEI and established DEI committees at all Stahl sites. In addition, to strengthen communication, engagement and collaboration across the workforce, Stahl also established an internal workplace hub, MyStahl.

With the aim to help the denim industry reduce the environmental impact of its wastewater and move towards circularity, Archroma, G-Star RAW and Advance Denim have renewed their joint commitment to the production of aniline-free denim apparel based on Archroma’s DENISOL® PURE INDIGO 30.

Their joint aim is to produce high-quality denim in authentic blue shades without the aniline impurity carried through from the synthesis of standard synthetic indigo. In traditional denim production, this aniline remains bound with the indigo pigment on the fabric; the remaining aniline is discharged during the dyeing and washing process. This can be a problem because aniline is toxic to aquatic life and two-thirds of aniline waste currently ends up in wastewater discharge where it could potentially pollute waterways and the ocean.

Archroma developed DENISOL® PURE INDIGO 30 to answer this key challenge. A 30% pre-reduced indigo solution, DENISOL® PURE INDIGO 30 makes it possible to produce indigo-dyed denim without aniline impurities throughout the process.

Easy to use with automated dosing, DENISOL® PURE INDIGO 30 reduces the water needed for preparation, washing and wastewater treatment compared to indigo grains. It also reduces hazardous chemical consumption while allowing high reproducibility and creating the authentic and iconic deep indigo shades traditionally associated with denim.

G-Star RAW is working towards making 20% of its entire collection from Cradle to Cradle Certified® fabrics by 2025. Its partnership with Archroma and Advance Denim contributes to this goal, since the aniline-free DENISOL® holds a Gold Level Material Health Certificate from the Cradle to Cradle Products Innovation Institute. DENISOL® PURE INDIGO 30 is also compliant with other eco-standards and the requirements of leading retailers and brands.

Advance Denim, G-Star RAW and Archroma have previously collaborated to launch collections based on Archroma’s EarthColors® technology, which upcycles plant waste from the herbal industry to create sustainable colorways.

Stahl has achieved Zero Discharge of Hazardous Chemicals (ZDHC) MRSL 3.1 Gateway certification for 2,151 products in its portfolio. This achievement underlines Stahl’s ongoing commitment to the ZDHC mission of achieving high standards for sustainable chemical management.

ZDHC certification enables companies working in the footwear, apparel and accessories value chains to demonstrate their commitment to responsible chemical management, with the ultimate goal being zero discharge of hazardous chemicals. Level 3 certification represents the highest level of conformity with the ZDHC certification programme. To achieve this, Stahl’s formulated chemical products and raw materials were verified and tested against ZDHC’s latest Manufacturing Restricted Substances List (MRSL 3.1) by Eurofins | Chem-MAP®. The Chem-MAP® programme was also used to audit the chemical management and stewardship processes at three of Stahl’s manufacturing sites.

The priority of sweater manufacturers has always been to select ingredients and fibers that are soft, hypoallergenic, and of the finest quality to meet consumer expectations that their sweaters are comfortable yet durable and easy to care for. According to the recent Eastman consumer study of sweater lovers, the sweaters consumers want to add to their wardrobes are soft, comfortable, stylish, and versatile. However, consumers are very disappointed when their sweaters look and feel differently after wearing and washing. Choosing fibers and materials that deliver comfort, quality and ease of care is essential to win with consumers. Today, these are compounded by the ever-present consumer demand for a sustainable paradigm. The promise of Naia™ from Eastman is exactly to make sustainable style accessible to brands and inclusive for everyone through a portfolio of fibers that doesn’t compromise on quality, comfort, or garment care.

The results of soft and cozy blends between the versatile Naia™ fibers and other materials can be appreciated in the collections of Naadam and The Gap, which this year presented its third collection of men's sweaters blended with Naia™ and cotton. By using Naia™ blended knits in their collections, brands are not just choosing a sustainable ingredient, but also a certified and circular supply chain: all Naia™ cellulosic fiber is produced in a safe, closed-loop process where solvents are recycled back into the system for reuse. Eastman Naia™ partners with Textiles Genesis to provide track and trace solutions for brands. All Naia™ fibers are OEKO-TEX™ STANDARD 100 certified, ensuring no use of hazardous chemicals, and certified by TÜV AUSTRIA as biodegradable and compostable, also in the ocean, as supported by a recently published ocean degradation study conducted by Woods Hole Oceanographic Institution (WHOI).

Naia™ fibers are designed to create unlimited possibilities for uncompromising, sustainable style: among these, Naia™ Renew staple fiber permits to create eco-conscious blends that are supremely soft, quick-drying and consistently reduce pilling which are ideal for T-shirts, casual wear, sweaters, comfy pants and home textiles. Produced from 60% sustainably sourced wood pulp and 40% certified* recycled waste materials, Naia™ Renew creates the same top-quality fabrics as traditional Naia™ fibers, but with a reduced carbon footprint of around 35% — and it’s available at scale. The innovative cellulosic acetate materials can be blended with cotton, modal, merino wool, recycled polyester, or multiple content fancy yarns. Naia™ blended yarns deliver super softness for supreme wearing comfort in knitwear, and sweaters made with Naia™ Renew can have good dimensional stability and shape retention even after multiple washes. Versatile Naia™ denier sizes can be used in different yarn spinning processes, giving the yarn spinners freedom of creativity for trendy yarn designs perfect for year-round basic sweaters with good quality and a durable look. The unique cross section of Naia™ staple fibers enables designs that accommodate four seasons of wearing comfort.

Since April 2023, the testing service provider Hohenstein has been testing and certifying in two new areas in the field of protective clothing: protective suits and gloves against chemicals and infectious agents. These are covered by Regulation (EU) 2016/425 and are therefore personal protective equipment (PPE).

Protective clothing against infectious agents is used in many types of work: for example, work at sewage plants, waste disposal, animal care, disposal of hazardous waste from hospitals, etc. Workers are exposed to unknown infectious agents (microorganisms, parasites). The protective clothing should protect wearers from the mediums in which the microorganisms are contained, such as liquids, aerosols or solid dust particles.

Hohenstein tests and certifies the following types:

• EN 14605: Protective clothing against liquid chemicals: Liquid-tight (type 3) or spray-tight (type 4) as well as partial protection types PB[3] and PB[4]
• EN 13982-1: Protective clothing against airborne solid particulates: Type 5
• EN 13034: Protective clothing against liquid chemicals: Type 6 and PB[6]

Sustainable solutions provider Perstorp has added new corporate sustainability targets, for water and waste, to its sustainability strategy. Its long-term sustainability ambition is to become Finite Material Neutral, which involves water and waste, along with raw materials, energy and catalysts. In 2021 the company set its first 2030 targets, for greenhouse gas emissions (using approved science-based targets) and (eco) toxic impact. Now Perstorp has added new sustainability targets that will address its long-term ambition.

These new 2030 corporate targets (all measured using 2019 as the base year) are:

• 30% absolute reduction of freshwater consumption
• 30% absolute reduction of hazardous waste directed to disposal
• 30% absolute reduction of non-hazardous waste directed to disposal

"Fresh water consumption and waste are two areas of big importance in reducing our environmental impact and working toward increased circularity," says Anna Berggren, Vice President Sustainability at Perstorp Group. "Fresh water scarcity is already a fact around the world, and we have a responsibility to reduce our consumption and utilize alternative water sources. We must also minimize waste generation and find new circular solutions of reusing and recycling the waste streams into new products, either ourselves or so that a third party can use them as raw material. We have set ambitious and absolute sustainability targets, that are to be achieved regardless of production growth. To be able to reach these targets we have several large projects planned that will contribute significantly."

All Perstorp production plants use water for multiple purposes, including, for example: for cooling, as a solvent for chemical reactions, as a carrier for products, and as a heat-transfer medium. One way to reduce fresh water consumption is to purify and recycle wastewater. Perstorp sees this as an important core technology and is planning to invest in wastewater recycling projects at several of its production sites.

A key to reducing waste directed to disposal is to develop circular solutions that use waste streams as raw materials for new products. One example is Project Air, in which captured carbon dioxide together with residue streams from Perstorp's production plant in Stenungsund, Sweden, will serve as raw material for production of sustainable methanol that will replace all the virgin fossil methanol used by Perstorp in Europe.

• Best practices in chemical footprints

Indorama Ventures Public Company Limited (IVL), a global sustainable chemical company, received top ranking, for the second consecutive year, among the world's 54 largest chemical companies in the ChemScore ranking by ChemSec, for its efforts to reduce its chemical footprint.

IVL is also the only chemical company that uses the Substitute It Now (SIN) List to remove hazardous substances, market safer alternatives, use bio-based and hazard-free recycled feedstocks, and develop low-carbon products. This reinforces IVL’s purpose of ‘reimagining chemistry together to create a better world’ and underscores the company’s support for the United Nations Sustainable Development Goals (SDGs).

Factors that increased IVL’s score include its ambition to use 16% bio-based and 10% recycled raw materials (rPET) as feedstock by 2030, and safer green chemistry substitutions to reduce toxicity from raw materials and production processes. IVL’s Deja™ brand, offering the world's first carbon-neutral PET pellet solution, is a sustainable alternative to reduce environmental impact.

The ChemScore ranking was developed by ChemSec, the non-profit International Chemical Secretariat in Sweden that advocates for safer alternatives to toxic chemicals, provide investors with better information to assess companies with strong chemical management strategies, and increased transparency. The ranking covers hazardous chemical portfolios, the development of safer chemicals and circular products, chemical management and company transparency, and responses to controversies, lawsuits, and regulations.

Madewell has created a denim style using bluesign® APPROVED ISKO fabrics, prioritizing sustainability in the production of a pair of women’s denim jeans. The jeans are made with ISKO’s fabrics that are dyed and finished with bluesign® APPROVED chemical products and produced in a resource-conserving way with a minimum impact on people and the environment. ISKO’s Reform™ technology, one of the denim ingredient brand’s most successful patented stretch innovations, has obtained bluesign® APPROVED status, which is a unique challenge for a denim mill.

The bluesign® APPROVED label is awarded only to the bluesign® SYSTEM PARTNER manufacturers that meet the strict safety and environmental requirements of the bluesign® CRITERIA, such as ensuring production sites are safe for workers, reducing CO2e emissions and water consumption, as well as avoiding hazardous substances in production among many others.

The partnership will aim at eliminating hazardous Potassium Permanganate Spray and most manual processes in denim finishing, while reducing Greenhouse Gas emissions, water and chemical use in the process

Hong Kong based Epic Group, a leading garment manufacturer for global brands today announced its strategic partnership with CleanKore, a denim innovation and patent licensing company. This partnership aims at scaling the CleanKore patented yarn dyeing technology that provides numerous sustainability benefits for both the denim mill and garment manufacturer.

CleanKore patented technology changes the chemistry and the process used to dyeing yarns at the denim mills by keeping intact the white core of the yarn and only dyeing the surface. This technology significantly reduces water, chemicals and process time in the denim garment finishing stage.

Denim garment finishing often involves onerous manual processes such as handsanding and hand whiskering, spraying of harmful Potassium Permanganate (PP) (done by heavily protective equipment donned personnel), and multiple washing cycles. CleanKore technology coupled with lasers enable elimination of the PP spray process, significantly improving health and wellbeing of apparel workers, as well as emissions of harmful chemicals. Manual processes are eliminated in most styles and significantly reduced in others.

CleanKore technology also enables the reduction of wash cycles – reducing water, chemical use and process time, adding to the sustainability credentials of the end products. The products currently tested by Epic Group and CleanKore demonstrate up to 44% of water savings in garment finishing and up to 60% of energy savings in the fabric dyeing stage, along with the elimination of PP spray.

Through their partnership, Epic Group and CleanKore are planning to rapidly scale up the adoption of this technology in partnership with Epic Group’s customer base. In the first year, the partnership plans to reach over 4 million pairs of denim and working towards a scale of 15 - 20 million pairs of denim per annum in the next 3 years, converting a large portion of Epic Group’s denim production to CleanKore technology.

A new interview study from NGO ChemSec shows that there is a gap between supply and demand when it comes to recycled materials, causing confusion and bottlenecks. Among other things, suppliers go out of their way using elaborate trade schemes to reach the coveted ”100% recycled” tag, which – it turns out – is not that important to consumer product brands. Far more crucial aspects, according to several major B2C companies, are:

• Honest communication towards customers
• Comprehensive information from suppliers
• Clear standards for recycled material

These are some of the conclusions from NGO ChemSec’s survey and interview study with 26 highly well-known consumer product brands. All brands responded to a survey concerning their current plastic use, as well as their needs, expectations and challenges regarding using more recycled material, to enable the shift to a circular economy for plastics.

Ten of the brands then participated in in-depth interviews on the same topics:, Essity, H&M, IKEA, Inditex , Lego, Mars,  SC Johnson, Tarkett, Unilever and Walgreens Boots Alliance.

Is non-mechanical recycling the answer?
Only about ten percent of all discarded plastics is recycled today, which is of course not nearly enough to achieve a circular plastics economy. Despite ambitions and initiatives to reduce plastics use – replacing the materials with other, more sustainable ones – the “plastic tap” is not expected to be turned off anytime soon. Quite the opposite, which makes raising the recycling rates more important than ever.

Although commercially viable, traditional (mechanical) recycling is afflicted with severe flaws, such as legacy chemicals, quality and functionality issues, as well as the lack of clean and sorted waste streams. The brands cited quality and functionality issues as the main obstacles for using more recycled material in their products.

This opens up for non-mechanical recycling, sometimes referred to as chemical recycling, where the plastic is either dissolved or broken down into smaller building blocks. Harmful additives and other hazardous chemicals can be removed in the process, and a material comparable to virgin plastic can be achieved – at least in theory.

So far, however, non-mechanical recycling technologies are costly, energy-intensive, and often require the addition of a great deal of virgin plastic to work – the very material that needs to be phased out.

The chain of custody models needs to be detangled
Apart from these production issues, there is a wide range of chain of custody models surrounding non-mechanical recycling, including mass balance and book & claim, which enable trade of credits or certificates for recycled material.

This cuts the physical connection between input and output, making it possible for a supplier to sell a material as “100% recycled”, when the actual recycled content could be zero.

This is a major issue for the brands ChemSec has spoken to, who value honest and correct communication towards customers. It turns out, perhaps somewhat surprisingly, that being able to slap a “made from 100% recycled plastic” label on a product is not all that important to brands.

To the brands, a physical connection between input (the discarded plastic waste headed for recycling) and output (the product at least partially made from recycled plastics) is far more important.

A physical connection, along with correct and adequate information from suppliers, as well as clearer standards and guidelines than what is available today, is what brands require to increase the use of recycled material and move us closer to a circular economy for plastics.
