From the Sector

Stahl, an active proponent of responsible chemistry, has published its 2021 Environment, Social, and Governance (ESG) Report. The report outlines the company’s sustainable development ambitions and its achievements over the year. It also features Stahl’s ambitious climate mitigation targets for 2030, such as the transition to more renewable feedstocks.

The 2021 Stahl ESG Report is a cornerstone of Stahl’s commitment to reporting transparently on its progress toward a more sustainable chemicals value chain. This acknowledges the important role that industry must play in tackling climate change while enabling a higher quality of life for more people. A key focal point of the new report is a progress update on Stahl’s ESG Roadmap. Introduced last year, this ten-year plan outlines the company’s ESG commitments and targets for 2023 and 2030.
 
Climate action
Stahl is focused on mitigating climate change by reducing greenhouse gas (GHG) emissions from all activities over which it has influence. This includes investing in renewable energy and process efficiencies to lower the GHG emissions caused directly by Stahl’s own operations and the energy used to power them. On this point, progress was made toward the 2023 and 2030 targets in 2021, including a reduction in Scope 1 and 2 CO2 emissions of 15%. Also covered are Stahl’s indirect value-chain impacts, for example, from the raw materials it buys. Looking beyond Stahl’s direct environmental impacts and fostering greater supply-chain transparency will be vital for tackling emissions on a wider scale.

Creating responsible chemistry, together
In 2021, advances were made regarding the company’s diversity and safety targets, which are areas of continuous improvement. Stahl is committed to ensuring a safe working environment, as well as nurturing a diverse and inclusive workplace to continuously improve employee skills.

EcoVadis Gold rating
Fostering ethical behavior through exemplary leadership and governance is key to Stahl’s ambitions. Achieving the EcoVadis Gold rating was an important milestone in this respect. This well-established award reflects the company’s ongoing commitment to supply chain transparency and working with partners to improve the sustainability of its products and operations.

• Long-awaited metal-free* and halogen-free* NYLOSAN® S NAVY and BLACK COLORS for Sportwear
• Iconic black and navy polyamides of major sportswear brands can finally be perfectly matched with safer dyestuffs
• Significant resource savings when dyeing with Archroma new signature CONSCIOUSLY DEEP system

Archroma, a global leader in specialty chemicals towards sustainable solutions, today announced the addition of two new metal-free* and halogen-free* acid dyes in its Nylosan® S range.

Dark shades represent approximately 80% of the outdoor and sportswear textile market, which is also under pressure to offer more sustainable articles. In this context, the new Nylosan® Navy S-3R and Black S-3N, especially developed by Archroma for polyamides and blends, meet four long-standing market demands for blacks and navies.

• First, the Nylosan® S range offers metal-free* alternatives to dyestuff generally used to dye polyamide and nylon and which usually contain metals. The new Nylosan® Navy S-3R and Black S-3N are taking the industry standard one step further by offering a halogen-free* option to those manufacturers, brands and retailers who are looking to offer the safest grade available.
• Second, the Nylosan® S range now comprises a wide gamut of colors, with these new dyes targeting the color matching and fastness specifications of the iconic blacks and navies of major sportswear brands. In order to support this color matching process, Archroma makes available the colorimetric dye primaries for the mills in order to (re)match the color standards.
• Third, the new navy and black dyes display the same color constancy as the dyes used in many leading color standards, which means the navy and black colors created with Nylosan® S range will be non-metameric to the color standard under multiple light sources, whether artificial or natural, indoor or outdoor.
• And fourth, the introduction of the new Nylosan® Black S-3N makes dyeing a metal-free* black on polyamide finally possible – something that was not available before.

Both dyes display the other usual features allowed of the Nylosan® S range, i.e., high fastness and buildup, and a wide shading gamut for industry-leading metal-free* acid dyes. They are REACH registered and bluesign® approved.

In addition, with the new Nylosan® Navy S-3R and Black S-3N at the core of its new CONSCIOUSLY DEEP system, Archroma is offering another very welcome benefit in the production of polyamide articles: resource saving. As most sportswear manufacturers and brands know, creating durable dark colors on nylon is a complex process that uses massive amounts of water and energy. Archroma therefore designed the new CONSCIOUSLY DEEP system to allow a highly efficient scour dyeing process reduced from 6 to 2 baths. This results into reducing the process time by up to 36%, water consumption by up to 64%, energy by up to 46%, and CO2 emissions by up to 41% compared to conventional benchmark process.

• ADNOC and Borealis confirm final investment agreement to build Borouge 4 in Ruwais, United Arab Emirates (UAE), which will produce 1.4 million tons of polyethylene per annum
• Expansion project includes construction of a 1.5 million tonnes ethane cracker, two state-of-the-art Borstar® polyethylene plants and a cross-linked polyethylene plant
• Borouge 4 will meet growing customer demand across the Middle East, Africa and Asia with differentiated polyolefin solutions in energy, infrastructure, and advanced packaging
• New facility will benefit from industry-leading technologies to significantly improve energy efficiency and lower emissions, with carbon capture study underway
• Upon expansion, Borouge will be the world's largest single-site polyolefin complex and will supply feedstock to TA'ZIZ Industrial Chemicals Zone Body

ADNOC and Borealis AG signed an USD 6.2 billion investment agreement to build the fourth Borouge facility – Borouge 4 – at the polyolefin manufacturing complex in Ruwais, United Arab Emirates (UAE).

The world-scale expansion confirms both partners’ commitment to the growth of Borouge and to support chemical production, and advanced manufacturing and industry in Ruwais, a key pillar of Abu Dhabi and the UAE’s technology, innovation and industrial development strategy. Borouge produces crucial industrial raw materials, which are exported to customers globally and used by local companies, boosting local industrial supply chains and enhancing In-Country Value.

Borouge 4 will capitalize on the projected growth in customer demand for polyolefins, driven by their use in manufactured products in the Middle East, Africa and Asia. The facility will also enable the next phase of growth at the Ruwais Industrial Complex by supplying feedstock to the TA’ZIZ Industrial Chemicals Zone.

Borouge 4 will have an industry-leading focus on sustainability leveraging the capabilities of both shareholders. The facility will utilize Borealis’ proprietary Borstar technology, to produce a product portfolio focused on durable applications for energy, infrastructure, advanced packaging, and agriculture sectors. This unique technology, in combination with hexene co-monomer, will enable the production of advanced packaging grades with up to 50% recycled polyethylene content.

Subject to an in-depth study, a Carbon Capture unit that would reduce CO2 emissions by 80% could also be operational in time for Borouge 4’s start-up. The facility is also designed to capitalize on ADNOC’s recent initiatives on clean energy, decarbonizing its power supply through access to Abu Dhabi’s clean power sources. These initiatives are aligned with the UAE Net Zero by 2050 Strategic Initiative.

The first Borouge facility, producing 450,000 tons of polyethylene per annum was commissioned in 2001. Borouge 2 and Borouge 3 took capacity to 2 million tons and 4.5 million tons of polyethylene and polypropylene per annum in 2010 and 2014 respectively.  Borouge 4 will boost the company’s annual polyolefin production to 6.4 million tons, making Borouge one of the world’s largest single-site polyolefin facilities.

The new Borouge 4 facility will comprise:

• An ethane cracker, with 1.5 million tons ethylene output per annum, which will be the fourth cracker in Borouge’s integrated petrochemical complex in Ruwais
• Two additional Borstar® polyethylene (PE) plants, each with 700 thousand tons per annum capacity, using state-of-the-art Borealis Borstar third generation (3G) technology
• A cross-linked PE (XLPE) plant of 100 thousand tons per annum capacity.
• A hexene-1 unit, which will produce co-monomers for certain grades of polyethylene.

• Alchemie Technology asks world leaders to cut energy and CO2 emissions from global fashion industry

Alchemie Technology, innovator of low energy, waterless, textile dyeing and finishing technology, is calling on COP26 leaders to support the global fashion industry in the adoption of new manufacturing technology, which will dramatically reduce carbon emissions and fashion’s impact on climate change.

While the fashion industry is one of the most polluting on the planet, second only to oil and gas, and greenhouse gas emissions from textile dyeing at around 3% of global emissions outweigh that of all international flights and maritime shipping combined, it is an industry that can also reduce CO2 emissions the fastest, just by changing the way it dyes fabrics.  

Fabric dyeing is the most polluting part of fashion and activewear manufacturing, involving industrial scale dye baths and huge amounts of dye chemicals, steam, electrical power, and consequent high CO2 emissions.  Repeated washing of the dyed fabric, required to remove dye residue, is responsible for 20% of the world’s wastewater pollution and excess dye is discharged into waterways, affecting the health of some of the world’s poorest communities. In more regulated areas, water pollution is reduced through reliance on energy intensive water treatment plants.

However, an environmental step change can be achieved by adopting new digital technology that can dye fabrics with an 85% reduction in energy consumption and a dramatic 95% reduction of the 1.3 trillion litres of water currently used by the industry each year.

For example, dyeing one polyester shirt using current methods generates 4.5 litres of wastewater and produces 0.17 Kg of CO2, compared to low energy digital technology, which uses less than 0.2 litres of water and reduces carbon emissions to 0.03 Kg.  Multiply these numbers by the billions of garments dyed each year and the scale of the environmental problem, if nothing changes, is clear to see.  Equally, the amount by which the textile industry can improve its carbon footprint is dramatic and can be done quickly if action is taken now.
Dr Simon Kew, Managing Director, Alchemie Technology comments “The technology now exists to enable the textile industry to make a significant contribution to helping meet the world’s net zero, climate change goals. But it requires the support of governments through investment, grants and legislation and the critical effort of brands, and their manufacturing supply chains to work together to make the change.”

Buildings are responsible for approximately 40% of all energy consumption and 36% of CO2 emissions in the EU. Improving energy efficiency in buildings therefore has a key role to play in achieving the ambitious goal of carbon neutrality by 2050 set out in the European Green Deal. A new briefing from the European Pultrusion Technology Association (EPTA) discusses how composite materials can help improve the thermal performance of the building envelope to satisfy increasingly stringent energy efficiency regulations. The EPTA report, Opportunities for pultruded composites in energy-efficient buildings, explains how pultruded profiles offer durable,  low maintenance solutions which can help reduce both operational and embodied carbon emissions from buildings in applications including energy-saving windows, thermal break connectors, and solar shading and cladding systems.   

“Economic and population growth mean energy demand is set to rise, making energy efficiency measures even more critical,“ comments Dr Elmar Witten, Secretary of EPTA. “Regulations and standards will continue to push for lower U-values for building elements, driving the increase use of materials and designs which minimise operational carbon emissions. Pultruded profiles offer an attractive combination of properties for designers of energy-efficient buildings – low thermal conductivity to minimise thermal bridging, together with excellent mechanical performance, durability, and design freedom.“  
 
It is estimated that today, roughly 75% of the EU building stock is energy inefficient, meaning that a large part of the energy used goes to waste. This energy loss can be minimised by improving existing buildings and striving for smart solutions and energy efficient materials for new builds. Areas of focus include improving glazing systems, better insulation of envelope components, and reducing unwanted solar heat gains. The low thermal conductivity of composites is being exploited in components and structures that help to minimise energy required for space conditioning.

Kornit Digital Ltd., a worldwide market leader in digital textile production technologies, released its 2020 Impact and Environmental, Social, and Governance (“ESG”) Report. This inaugural report affirms Kornit’s commitment to achieving specific ESG goals. This includes the way Kornit conducts business, creates meaningful impact in local communities, and achieves environmental sustainability, in addition to how Kornit will continue to build a diverse and inclusive company culture, foster employee growth and development, and empower fair and safe labor practices globally.
 
In addition to enabling eco-friendly production processes with technology and consumables that use less water, reduce waste, and minimize the carbon footprint, Kornit technology solutions enable sustainable production on demand, which eliminates overproduction of apparel and other textile goods. A 2021 Life Cycle Assessment conducted on two flagship products, the Kornit Atlas MAX and Kornit Presto S, demonstrated that relative to traditional analog processes, Kornit’s digital production systems used up to 95% less water and 94% less energy, and produced up to 83% less greenhouse gas (GHG) emissions for the Presto S system and up to 93% less water and 66% less energy, and produced up to 82% less greenhouse gas (GHG) emissions for the Atlas MAX system.

Based on this study, in addition to past sustainability performance results and strategic projections for business growth and market expansion, by 2026 Kornit Digital’s sustainable on-demand solutions are expected to enable the production of approximately 2.5 billion apparel items in a responsible manner to deliver:

• Zero overproduction: By moving the industry to on-demand manufacturing, Kornit will help eliminate the estimated 1.1 billion apparel items overproduced using traditional production methods, based on an industry average of 30% overproduction. This is about 1 apparel item for each and every person living in Europe and North America – saved.
• Zero water waste: In addition to eliminating overstocks, Kornit-enabled production on demand will support saving an estimated 4.3 trillion liters (1.1 trillion gallons) of water. This is the estimated amount of drinking water needed for the entire U.S. population for 11 years.
• Reduced CO2 emissions: By enabling sustainable on-demand production, consuming less energy, and generating less waste, Kornit will prevent an estimated 17.2 billion kilograms (37.9 billion pounds) of greenhouse gas emissions, compared to traditional manufacturing methods. This is equivalent to the estimated amount of carbon dioxide emitted from circumnavigating the entire planet with a car nearly 2,400 times.

Furthermore, the report outlines Kornit’s commitment to achieving KPIs that address waste, chemicals, GHG emissions, energy, product development, employee training, diversity and inclusion, and the company’s supply chain.

Autoneum carpet systems already meet high standards of sustainable mobility due to their high content of recycled fibers. Thanks to an alternative backcoating (ABC) process, Autoneum carpets are now becoming even more environmentally friendly: By replacing the latex commonly used in standard backcoatings with thermoplastic material, the recyclability of carpets at the end of product life is further  improved. In addition, the innovative manufacturing process greatly reduces water and energy consumption and thus CO2 emissions in production.

Lightweight, textile-based carpet technologies such as Di-Light or Relive-1 significantly improve the environmental performance of carpets. For example, Di-Light-based carpets consist of up to 97% recycled PET; aside from that, they are around 20% lighter than conventional needlepunch carpets, thus contributing to lower fuel consumption and CO2 emissions from vehicles. In addition, Autoneum needlepunch carpets are now even more sustainable thanks to the innovative ABC process, which uses a thermoplastic adhesive instead of latex in the backcoating: Unlike latex, thermoplastic adhesives can be heated and melted down together with the carpet components made of pure PET at the end of the product life cycle, which facilitates recycling considerably. Furthermore, since the fibers of the thermoplastic mono-material are easier to open, carpet cut-outs can be reclaimed more easily, thereby reducing the consumption of natural resources as well as waste volumes and thus CO2 emissions. The environmental  performance of Autoneum’s needlepunch carpets, which already contain a high proportion of recycled PET, is thus further improved.

Moreover, backcoatings without latex improve the sustainability of carpets not only thanks to better recyclability at the end of the product life cycle. Since the application of the thermoplastic adhesive using the innovative ABC process consumes significantly less energy than the production of latexbased backcoatings and does not require any water at all, the environmental impact can already be minimized in the manufacturing process. Additionally, thermoplastic adhesives developed in-house by Autoneum will open up new possibilities in the future for adapting backcoatings to the individual needs of vehicle manufacturers in terms of their acoustic performance, stiffness and abrasion resistance.

Models from various customers in Europe and North America are already equipped with latex-free needlepunch carpets from Autoneum. In the near future, backcoatings with thermoplastic adhesives will also be used for Autoneum’s tufted carpets. Production of the new, even more sustainable generation of tufted carpets is scheduled to start in early 2022.

• CO₂ emissions will be reduced by 320,000 tons per year
• First supplier of wood-based cellulosic fibers in China to completely eliminate coal
• Share in eco-responsible specialty fibers will be significantly increased
• Lenzing is strategically well on track with these investments

The Lenzing Group, the leading global supplier of wood-based specialty fibers, will invest more than EUR 200 mn in its production sites in Purwakarta (Indonesia) and Nanjing (China) to convert existing standard viscose capacity into environmentally responsible specialty fibers.

In Nanjing (China) Lenzing will establish the first wood-based fiber complex in China that is independent from coal as an energy source. By using natural gas based cogeneration, Lenzing will reduce CO₂ emissions at the site by more than 200,000 tons. At the same time a line of standard viscose will be converted to a 35.000 tons TENCEL™ branded modal fibers line making Lenzing (Nanjing) Fibers Co., Ltd a 100 percent wood-based specialty fiber site by the end of 2022.

In Purwakarta (Indonesia), Lenzing will reduce its CO₂ emissions by increasingly using biogenic fuels. Additional investments to reduce emissions to air and water will make this facility fully compliant with the EU Ecolabel by the end of 2022. That will allow converting standard viscose capacity into LENZING™ ECOVERO™ branded fibers for textile applications as well as LENZING™ Viscose Eco fibers for personal care and hygiene applications. As a result, the site in Indonesia will also become a pure specialty viscose supplier as of 2023.

Both investments are fully in line with Lenzing’s target to reduce its greenhouse gas emissions per ton of product by 50 percent by 2030. By avoiding or reducing the use of fossil fuels at the two sites, the Lenzing Group will be able to reduce CO2 emissions by more than 320,000 tons in total, or 18 percent, compared to 2017. In addition, this investment allows Lenzing also to reduce its total sulfur emissions by more than 50 percent, compared to 2019.

Together with its major lyocell fiber project in Thailand, Lenzing will also boost its share in specialty fibers as a percentage of fiber revenues to well above the targeted 75 percent already by 2023, which in turn is an important step towards achieving the company’s EBITDA target of EUR 800 mn by 2024.

Flax has accompanied people for thousands of years, in linen fabrics, in ropes, as insulation material. And until the present day. With woven tapes made of flax, vombaur makes the functional and ecological advantages of natural fibres available for lightweight design.

Lightweight and firm
Flax fibres are particularly rigid and tear-proof. Textiles made of the natural material therefore give natural fibre reinforced plastic (NFP) special stability. Additionally, flax has a low density. The components thus combine high rigidity and strength with low weight. Another functional plus: natural fibre reinforced plastics are less prone to splintering than glass fibre reinforced plastics.

Sustainable material
The cultivation of flax binds CO2 and the production of NFP generates 33 percent lower CO2 emissions than conventional fibre reinforced plastics. The energy consumption is 40 percent lower. This reduces production costs and improves the material's CO2 footprint. Punch-packing arguments for natural fibre tapes – like flax tape by vombaur – in lightweight design applications.

Circular Economy
Circular Economy – this also works in lightweight design. The number of recycling cycles without loss of quality is higher for natural fibre reinforced plastics than for glass or carbon fibre reinforced plastics: the thermoplastic matrix of the composite can be melted and recycled after a product life cycle. The natural fibres can "live on" in other products – injection moulded products for example.

Versatile applications
"Composites from our flax tapes are used to reinforce high-tech skis as well as for extruding state-of-the-art window sections – the applications are countless," explains Tomislav Josipovic, Sales Manager with vombaur. "As a development partner, we support applications for the automotive, wind energy, construction, sports and many other industries with our composite textiles."

Sustainability and environmental responsibility are important developments for the current design of productions and products. In order to obtain a comprehensive evaluation of the potential of bio-based composites, the AZL, together with an industry consortium, is investigating the market potential, future applications and relevant technologies for bio-based composite materials. The 5-month market and technology study will start on October 22nd, 2020 and is open to interested companies. Companies such as REHAU, an Automotive Tier 1, Asahi Kasei, Johns Manville, Mahr Metering Systems and several material manufacturers are participating in the study.

Bio-plastics are well established in industry, especially in packaging applications. The market for biopolymers is expected to grow from USD 10.5 billion in 2020 to USD 27.9 billion in 2025. At the same time, bio-based raw materials, such as natural fibers, are available on the market in a cost-effective manner. Composites with wood or natural fiber content are also increasingly used in products.

Dr. Michael Emonts, Managing Partner of AZL: "Together with our partner companies we want to identify hidden business potential for composites with bio-based materials. To do so, we will reapply our established approach for market and technology studies: Based on a detailed market analysis, we will dive deep into the technological evaluation of technologies, applications and business cases.”

Based on a detailed market segmentation, AZL's technology experts analyze the various market segments in terms of their size, growth potential, relevant players and existing and future applications. For the identified applications, the participants in the study will receive detailed insight into the respective technical and legal requirements as well as an overview of value chains, processes and materials. In the following, the strengths and challenges of bio-composites compared to conventional materials are elaborated. The consortium will select the components with the highest potential, for which suitable production scenarios will be developed and analyzed in terms of costs in a business case analysis.

"We are participating in the AZL study to identify and evaluate new product areas with bio-materials. The technological analyses of the AZL studies have already helped us in the past to initiate new developments," says Dr. Steven Schmidt, Director Technology Platforms Materials at REHAU, explaining the motivation for working with the AZL and the industry consortium. "As one of the 50 Sustainability & Climate Leaders, we at REHAU are incorporating environmentally friendly materials into more and more products. Wherever the company is active - from the furniture and construction industries to the automotive industry - REHAU is already developing and manufacturing high-quality products from recycled raw materials. By 2025, REHAU plans to increase its recycling rate across the Group to significantly more than 15 percent and at the same time reduce CO2 emissions by at least 30 percent," adds Dr. Steven Schmidt.

Bio-composites will also be the topic of the upcoming Lightweight TechTalk by AZL on September 29, 2020. Experts from industry and academia will give technology and market insights on sustainability and recycling of composites in 6 presentations. Registration is free of charge at: https://azl-aachen-gmbh.de/termine/recycling-of-composites/.

The kick-off of the project will take place on October 22nd, 2020 in the form of a video conference. Further background information on the project can be found under the following link: https://azl-aachen-gmbh.de/wp-content/uploads/2020/09/2020-251_OP_Bio-Bases_Composites.pdf
