From the Sector

Setting concrete environmental sustainability objectives for abating direct greenhouse gas emissions and leveraging investments and state-of-the-art technology. This is the approach that has always guided RadiciGroup in operating its businesses with a wide range of products: chemical intermediates, polyamide polymers, high performance engineering polymers and advanced textile solutions.

Between 2011 and 2020, overall Group greenhouse gas emissions were cut by 70%, falling from about 700,000 metric tons per year of CO₂ equivalent to 200,000 metric tons.  

These results were largely achieved through the action implemented by the Group’s Specialty Chemicals Business Area at its plants in Novara, Italy, and in Germany, which are the heart of RadiciGroup’s chemicals business. Here the Group produces an essential intermediate for synthesizing polyamide 66, adipic acid, whose production process releases nitrous oxide as a by-product. Nitrous oxide in itself is not particularly problematic (in fact, it is used in the medical sector as an anaesthetic and in the food industry as a spray propellant, in cans of whipped cream, for instance), but, if it is released into the atmosphere, it has a much higher greenhouse gas effect than carbon dioxide.

At the Radici Chimica site in Novara, a multiyear investment budget of over EUR 10 million was dedicated to lowering these emissions through three important undertakings: in 2004, putting into operation a three catalyst bed reactor, designed and patented by the company, to decompose nitrous oxide into nitrogen and oxygen, the two elements it is composed of, thus making it innocuous for the atmosphere; in 2013, installing an EnviNOx plant to decrease the release of nitrous oxide formed in the production of nitric acid, and, in 2021, a further improvement in the emissions abatement system associated with nitric acid production.

Since activating the last plant just 9 months ago, more than 35,000 metric tons of CO₂ equivalent have been cut. All the above-mentioned actions have enabled Radici Chimica Novara to record a nitrous oxide emissions level less than 10 ppm, a value close to zero.

Archroma, a leader in specialty chemicals towards sustainable solutions, has announced the launch of a collaboration with the University of North Carolina Greensboro (UNCG) and its Consumer, Apparel, and Retail Studies (CARS) department, aiming to further the education of its students in the area of color management expertise.

As per the agreement, Archroma will donate its color management tools for their design projects, gaining hands-on expertise that equips them for successful careers in the fashion and textiles industries.

The students will have access to a complete set of the ready-to-use color library developed by Archroma for cotton and polyester. The library, well known among fashion designers and stylists as the Color Atlas by Archroma®, which was launched in 2016 to provide off-the-shelf color inspiration that can be implemented in production with just a few clicks.

Today, the Color Atlas contains 4’320 colors applicable on cotton poplin, almost the double compared to similar tools available to textile and fashion specialists, and 1,440 colors on polyester.

Beside the physical Color Atlas library, the students in the CARS program will also have access to the full digital files for use in the industry-leading 3D fashion design and development software Browzwear VSticher.

The students will be able to use the Color Atlas books and the digital data as a color selection resources to use in a variety projects and assignments.

Archroma, a global leader in specialty chemicals towards sustainable solutions, and Jeanologia, a world leader in sustainable and efficient technology development, joined forces to launch an eco-advanced alternative to the denim fabric washing process, including in some cases the mercerization, one of the most water-intensive and pollutant processes of denim fabric finishing.

It all starts with the spinning step where the cotton is turned into yarn. The second step is a pretreatment that will prepare the yarn for the dyeing step. The dyed yarn then goes through the sizing process, which is a treatment preparing it for weaving. At this stage, we have obtained a denim fabric that will go through a few more steps. First, the fabric may undergo a washing treatment or, in some cases, mercerizing treatment which consists of treating it with caustic soda in order to obtain a more lustrous, flat and less reddish blue and black denim.

In both traditional ways to clean the fabric, washing or mercerizing, multiple highly water intensive washings are required in order to restore optimal fabric pH and remove unfixed dyestuff and any undesired deposits or impurities from the fabric. One of such impurities released in the washing process is aniline, a substance that is classified as a category 2 carcinogen and considered toxic to aquatic life.

That is why Archroma and Jeanologia decided to team up and develop an alternative to the traditional fabric cleaning process and its subsequent water-intensive and water-polluting washings.

• The breakthrough alternative to the fabric cleaning concept presented by Jeanologia and Archroma combines the use of the aniline-free* PURE INDIGO ICON dyeing system of Archroma, and the water-free** and chemical-free “G2 Dynamic“ finishing technology of Jeanologia.
• The Archroma/Jeanologia solution allows to create aniline-free* denim, and improve the final aspect of the fabric through a fully chemical-free and almost water-free** cleaning alternative treatment.
• The Archroma/Jeanologia solution can also be used with additional Archroma coloration systems such as INDIGO REFLECTION or PURE UNDERTONES.

Umberto Devita, Business Development Manager at Archroma’s Competence Center for Denim & Casual Wear, who was the project leader for this new development, comments: “At Archroma, we strive to develop solutions in line with our principles of “The Archroma Way to a Sustainable World: Safe, efficient, enhanced, it’s our nature”. It was therefore very inspiring to work with a partner who shares the same values of developing efficient new processes to bring all know-how to our customers to maximize value – for denim that looks as good as the good it creates.”

For Jean-Pierre Inchauspe, Business Director of G2 Dynamic at Jeanologia, “this association is another step to change traditional, more polluting and water consuming processes in the textile industry for new ones using technology, improving, and boosting subsequent production stages up to the finishing of the garment, making them more efficient and allowing companies to be more competitive, increase productivity and offer a product that is completely sustainable with high quality.”

• Instant access to ecotoxicological and regulatory information and certificates for Archroma specialty chemical products
• Faster decision-making and time-to-market for manufacturers, brands and retailers in the textile, paper, packaging, paint, and construction industries

Archroma, a global leader in specialty chemicals towards sustainable solutions, announced the launch of The Safe Edge, an online platform for instant access to product related regulatory & compliance certificates and information.

With continuously growing public awareness around the social, health and ecological impacts of human and business activities, the need for transparency and traceability in supply chains has become essential.

Time to market is equally critical, and manufacturers, brands and retailers need access to reliable information in real time.

The Safe Edge platform has been designed with that in mind: It allows brands, retailers and manufacturers of textile, fashion, packaging, paper, paints, to verify with just a few clicks the regulatory & compliance status of Archroma products, including regulations, ecotoxicological information & certifications, and brand requirements.

The Safe Edge covers standards, regulations and information such as air emission factors, animal origin, halal, kosher, plant origin, food contact, Blue Angel, bluesign®, Cradle-to-Cradle, chemical inventories, Composability EN 13432, conflict minerals, EU Flower/Ecolabel, GOTS, CONEG, ISEGA, Nordic Swan, Oekotex® Standard 100, California Prop 65, REACH, RoHS (Restriction of Hazardous Substance), Screened Chemistry, SDS, SVHC (Substance of Very High Concern), VOC (US), ZDHC (Zero Discharge Hazardous Chemicals), and brand standards (like Coats A&F MRSL, Decathlon RSL 2020, Jack Wolfskin RSL and The List IV by Inditex.

With the launch of The Safe Edge, Archroma continues to assert its leading role in driving sustainability in its industries, in line with its commitment to the principles of “The Archroma Way to a Sustainable World: safe, efficient, enhanced, it’s our nature”. The “Safe” principle in particular is at the core of the Archroma approach to sustainability, with the deeply rooted goal to protect people and the planet with products that are safe to use, and safe to wear.

The Safe Edge is already accessible for manufacturers, brands and retailers in Europe and Asia, and will be launched in North America in September 2021, and in Latin America by the end of the year.

DyStar, a specialty chemical company with a heritage of more than a century in product development and innovation, is pleased to announce their continued commitment to the protection of their global intellectual property portfolio.

As an innovative global chemical organisation, DyStar’s intellectual property portfolio is an important part of their DNA. To date, their innovation encompasses more than 1,000 patents, trademarks and patent applications worldwide.

Eric Hopmann, Chief Executive Officer of DyStar Group explains: “As DyStar continues to focus on managing challenges of the rapid global business recovery and exploring exciting growth opportunities across the emerging markets, our team needs to stay vigilant and vigorously protect our global intellectual property portfolio. This has again been demonstrated in a recent incident, where DyStar had to charge three former employees who had neglected to protect DyStar’s intellectual property, and were also under suspicion of having shared DyStar’s proprietary information with the competition.”

Archroma, a global leader in specialty chemicals towards sustainable solutions, and Jeanologia, a world leader in sustainable and efficient technology development, today announced the launch of ‘Pad-Ox G2 Cold’, a water-saving dyeing process at room temperature for casual looks.

Archroma initially introduced its eco-advanced Pad-Ox dyeing process for woven fabrics, and then used it as part of its ADVANCED DENIM concept. By combining the oxidation and fixation steps, it is possible to shorten the dyeing process and thus realize substantial resource savings in water, wastewater, cotton waste, and energy.

Over the years the company has worked with its textile manufacturers and partners to improve the Pad-Ox process, in particular woven applications such as chinos and casual wear. To achieve maximum positive impact, Archroma is using its Diresul® range of low sulfide sulfur dyes and, more recently, its innovative plant-based range of EarthColors®. A wide selection of dyes from these two ranges have received the Cradle-to-Cradle Product Innovation Institute’s Platinum Level Material Health Certification.

Meanwhile, Jeanologia has been working on the technology side, with laser and eco-finishing solutions for more than 25 years, accompanying the textile industry on their way to producing with zero discharge. In 2008, the company introduced its G2 Dynamic the first ozone treatment for continuous fabric that dramatically reduces the amount of water and chemicals used, while at the same time saving costs at the mill and eventually at the garment finishing facilities. This technology makes fabric more stable and consistent and prepares the fabric better for the use of other technologies like laser. This machinery can be used along with Pad-Ox technology to help cleaning fabric thus improve fastness results. While it allows process to work at room temperature.

Project focus on water saving
Archroma and Jeanologia therefore understandably decided to team up and combine their expertise in sustainable dyeing and finishing technologies. The objective of the project was to improve the Pad-Ox dyeing process even further, in particular in one area that still offered room for positive impact: temperature and fastnesses.

The new ‘Pad-Ox G2 Cold’ dyeing process works thanks to the insertion of very small machinery into the existing finishing range process, using cold processing and thus operating with much less water, carbon footprint and energy than traditional benchmark fabric finishing processes, whilst retaining the water and other resource savings offered by the Pad-Ox technology.

Maximum savings can be achieved by mills and garment manufacturers who wish to switch from a conventional dyeing process straight to ‘Pad -Ox G2 Cold’ to obtain high quality fabrics for comfortable and casual wear.

Reinach, Switzerland, and Westlake, Ohio, 2 February 2021 - Archroma, a global leader in specialty chemicals towards sustainable solutions, today announced a strategic partnership with technology innovator CleanKore, aiming to advance sustainable dyeing processes throughout the denim supply chain.

The agreement will allow Archroma and CleanKore to promote the benefits of each other’s technologies. This includes Archroma’s robust catalog of dyes and specialty chemicals along with CleanKore’s patented process of dyeing yarns at the denim mill that completely eliminates the need for potassium permanganate (PP) spray and laser booster to achieve the bright white abrasion effect in the garment finishing process. The result is a large and circular bright white core with a small ring of indigo dye. The technology does not just eliminate the chemicals associated in the PP spray and laser process, which is much safer for denim workers, it also allows to save significant amounts of water and energy throughout the manufacturing process from fabric to garmenting.

CleanKore initially looked at eliminating potassium permanganate due to its being classified as hazardous if inhaled or ingested, or in case of contact with the skin or the eye. It is also considered very toxic to aquatic life. No new equipment or capital expenses are needed to implement the CleanKore technology, which works on all denim fabric, including dark indigo, sulfur top/bottom and sulfur black.

This is where Archroma comes into the picture. Its global technical team of denim coloration specialists will provide support to denim mills seeking to implement the CleanKore technology and develop the desired looks and effects - with the right colors and chemical systems for their production set-up.

CleanKore estimates that the technology allows to save up to 15 liters of water per garment, or the equivalent to the drinking needs of 5 people per day, and up to 0.51 kWh of energy per garment, or the equivalent of five 100-watt light bulbs on for 1 hour. The CleanKore technology also leads to a 10% to 20% increase in production throughput, as a result of a faster garment wash-down and the elimination of PP spray.

For CleanKore CEO Darryl Costin Jr., the announcement comes at an ideal time for CleanKore: "We have successfully proven the technology with mill partners such as Arvind and other denim mills in Pakistan, Bangladesh, China, Vietnam, Thailand and the United States. The response from the industry has been overwhelmingly positive. Having a partner in Archroma, one that is highly respected for their innovation and emphasis on sustainability throughout the industry, will allow us to take CleanKore to the next level.”

Umberto Devita, Global Indigo Manager at the Archroma Global Competence Center for Denim & Casualwear, adds: "CleanKore is perfectly aligned with the 3 pillars of 'The Archroma Way to a Sustainable World: Safe, efficient, enhanced'. 'Safe' through the elimination of a potentially harmful substance and the protection of the denim workers, 'Efficient' through the reduction of resource consumption, improved productivity and cost-effective profile. And 'Enhanced' through the gorgeous colors and effects allowed with Archroma's innovations and systems, in particular our aniline-free* Denisol® Pure Indigo and Diresul® sulfur dyes. We look forward to help promoting an innovation that will help with many of the challenges facing our denim customers throughout the world. Because it’s our nature."

Archroma, a global leader in specialty chemicals towards sustainable solutions, today announced the release of its third Sustainability Report.

Prepared again in accordance with the Global Reporting Initiative (GRI) standards, and covering Fiscal Year 2019, the report outlines the company’s progress on its priority sustainability topics, such as human health and environmental safety, resource efficiency, sustainable sourcing and product stewardship, as well as diversity & inclusion, and talent management.

All activities described in the report support the 3 pillars of “The Archroma Way to a Sustainable World: Safe, efficient, enhanced. It’s our nature." This approach is the company’s guiding light in challenging the status quo to making its operations and its value chains sustainable.

“As our industries navigate through the COVID-19 pandemic, the temptation for some will be to push back on the urgent need to address the climate crisis. We cannot allow that. Because after all, it's our nature”, Heike van de Kerkhof, CEO of Archroma, comments.
