From the Sector

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.”

• More than 30 leading pioneers of the chemical and material sector welcome the latest political papers from Brussels, Berlin and Düsseldorf

The political situation for renewable carbon from biomass, CO2 and recycling for the defossilisation of the chemical and materials industry has begun to shift fundamentally in Europe. For the first time, important policy papers from Brussels and Germany take into consideration that the term decarbonisation alone is not sufficient, and that there are important industrial sectors with a permanent and even growing carbon demand. Finally, the need for a sustainable coverage of this carbon demand and the realisation of sustainable carbon cycles have been identified on the political stage. They are elemental to the realisation of a sustainable chemical and derived materials industry.

The goal is to create sustainable carbon cycles. This requires comprehensive carbon management of renewable sources, which includes carbon from biomass, carbon from Carbon Capture and Utilisation (CCU) – the industrial use of CO2 as an integral part – as well as mechanical and chemical recycling. And only the use of all alternative carbon streams enables a true decoupling of the chemical and materials sector from additional fossil carbon from the ground. Only in this way can the chemical industry stay the backbone of modern society and transform into a sustainable sector that enables the achievement of global climate goals. The Renewable Carbon Initiative’s (RCI) major aim is to support the smart transition from fossil to renewable carbon: utilising carbon from biomass, CO2 and recycling instead of additional fossil carbon from the ground. This is crucial because 72% of the human-made greenhouse gas emissions are directly linked to additional fossil carbon. The RCI supports all renewable carbon sources available, but the political support is fragmented and differs between carbon from biomass, recycling or carbon capture and utilisation (CCU). Especially CCU has so far not been a strategic objective in the Green Deal and Fit-for-55.

This will change fundamentally with the European Commission's communication paper on “Sustainable Carbon Cycles” published on 15 December. The position in the paper represents an essential step forward that shows embedded carbon has reached the political mainstream – supported by recent opinions from members of the European parliament and also, apparently, by the upcoming IPCC assessment report 6. Now, CCU becomes a recognised and credible solution for sustainable carbon cycles and a potentially sustainable option for the chemical and  material industries. Also, in the political discussions in Brussels, the term “defossilation” is appearing more and more often, complementing or replacing the term decarbonisation in those areas where carbon is indispensable. MEP Maria da Graça Carvahlo is among a number of politicians in Brussels who perceive CCU as an important future industry, putting it on the political map and creating momentum for CCU. This includes the integration of CCU into the new Carbon Removal Regime and the Emission Trading System (ETS).

As the new policy documents are fully in line with the strategy of the RCI, the more than 30 member companies of the initiative are highly supportive of this new development and are ready to support policy-maker with data and detailed suggestions for active support and the realisation of sustainable carbon cycles and a sound carbon management. The recent political papers of relevance are highlighted in the following.

Brussels: Communication paper on “Sustainable Carbon Cycles”
On 15 December, the European Commission has published the communication paper “Sustainable Carbon Cycles” . For the first time, the importance of carbon in different industrial sectors is clearly stated. One of the key statements in the paper is the full recognition of CCU for the first time as a solution for the circular economy, which includes CCU-based fuels as well. The communication paper distinguishes between bio-based CO2, fossil CO2 and CO2 from direct air capture when addressing carbon removal and it also announces detailed monitoring of the different CO2 streams. Not only CCU, but also carbon from the bioeconomy is registered as an important pillar for the future. Here, the term carbon farming has been newly introduced, which refers to improved land management practices that result in an increase of carbon sequestration in living biomass, dead organic matter or soils by enhancing carbon capture or reducing the release of carbon. Even though the list of nature-based carbon storage technologies is non-exhaustive in our view, we strongly support the paper’s idea to deem sustainable land and forest management as a basis for the bioeconomy more important than solely considering land use as a carbon sink. Surprisingly, chemical recycling, which is also an alternative carbon source that substitutes additional fossil carbon from the ground (i.e. carbon from crude oil, natural gas or from coal), is completely absent from the communication paper.

Berlin: Coalition paper of the new German Government: “Dare more progress – alliance for freedom, justice and sustainability”
The whole of Europe is waiting to see how the new German government of Social Democrats, Greens and Liberals will shape the German climate policy. The new reform agenda focuses in particular on solar and wind energy as well as especially hydrogen. Solar energy is to be expanded to 200 GW by 2030 and two percent of the country's land is to be designated for onshore wind energy. A hydrogen grid infrastructure is to be created for green hydrogen, which will form the backbone of the energy system of the future – and is also needed for e-fuels and sustainable chemical industry, a clear commitment to CCU. There is a further focus on the topic of circular economy and recycling. A higher recycling quota and a product-specific minimum quota for the use of recyclates and secondary raw materials should be established at European level. In the coalition paper, there is also a clear commitment to chemical recycling to be found. A significant change for the industry is planned to occur in regards to the so-called “plastic tax” of 80 cents per kilogram of non-recycled plastic packaging. This tax has been implemented by the EU, but most countries are not passing on this tax to the manufacturers and distributors, or only to a limited extent. The new German government now plans to fully transfer this tax over to the industry.

Düsseldorf: Carbon can protect the climate – Carbon Management Strategy North Rhine-Westphalia (NRW)
Lastly, the RCI highly welcomes North Rhine-Westphalia (NRW, Germany) as the first region worldwide to adopt a comprehensive carbon management strategy, a foundation for the transformation from using additional fossil carbon from the ground to the utilisation of renewable carbon from biomass, CO2 and recycling. For all three alternative carbon streams, separate detailed strategies are being developed to achieve the defossilisation of the industry. This is all the more remarkable as North Rhine-Westphalia is the federal state with the strongest industry in Germany, in particular the chemical industry. And it is here, of all places, that a first master plan for the conversion of industry from fossil carbon to biomass, CO2 and recycling is implemented. If successful, NRW could become a global leader in sustainable carbon
management and the region could become a blueprint for many industrial regions.

AMUT’s strategic partnership with EREMA contributes to accelerate the transition towards a greener world.  In summer 2021, EREMA in collaboration with AMUT  has finalized the installation and commissioning of ALTO packaging ́s first extrusion line for food grade PET sheets in New Zealand market. At the ALTO Plastic Packaging site, in Albany, the plant now processes 100 % washed post-
consumer flakes into 100 % food contact grade monolayer thermoforming sheet. In New Zealand, this milestone represents the first system to be installed for this special application.

The plastic packaging company ALTO, a division of PACT Group, invested for this new food grade PET sheet extrusion line as a part of Pact Group ́s vision to lead Circular Economy through Packaging in Australia and New Zealand.

Thanks to the direct combination of VACUREMA® PET recycling technology and the AMUT Inline Sheet production technology there is no longer any extra process stage. This is, because the melt goes straight from the VACUREMA® 1716 T Basic to the AMUT plant without the detour of pelletising. The post-consumer PET material is already decontaminated and pre-dried prior to extrusion in the vacuum reactor of the VACUREMA® Basic, with a throughput of up to 1,500 kg per hour. After high capacity filtration by EREMA SW-RTF backflush filter and online IV measurement, the melt goes directly into the AMUT Inline Sheet plant where it is processed into thermoforming sheet from 0.15 mm till 1.2 mm thickness. The monolayer thermoforming sheet produced from pure rPET is not only 100 % food contact compliant, it also fulfils the FDA and further regulations. At ALTO it is further processed into trays and food containers.

AMUT played its part by providing a full range of downstream equipment ranging from the Automatic Tdie, three rolls stack calender with automatic gap control and motorized cross axing unit, lamination unit for welding and barrier films, thickness control gauge to anti-static silicon coating unit, fully automatic two shafts turret winder and in line edge trims grinding and recycling.

The special features of this extrusion line come from the complete automatic and easy management of the line. This is due to the new Amut`s software including the Easy Start and Easy Change functions that will allow the operator to start the extrusion line and change product formats in automatic mode.

EREMA and AMUT are long-term partners in the Inline Sheet sector. EREMA ́s VACUREMA® technology is currently in use in more than 100 Inline Sheet facilities around the world, also for PACT Group companies in Australia. 

Sappi has approved an investment in Kirkniemi Mill in Lohja, Finland which enables a switch in its energy sourcing to renewable bioenergy. With this investment the mill’s direct fossil greenhouse gas emissions will reduce by ca. 90 percent, which is equivalent to 230 000 tons of carbon dioxide annually.

The project, set for completion in early 2023, will contribute significantly to Sappi Europe’s decarbonisation roadmap by exiting coal at one of its last facilities partially using this fuel type. Biomass will then be used in Kirkniemi’s multi-fuel boiler, built in 2015. The move advances Sappi towards its 2025 targets which include reducing specific greenhouse gas emissions (scope 1 and 2) by 25 percent and increasing renewable energy share to 50 percent in Europe compared to 2019.

The investment will establish the equipment needed to receive, store and handle woody biomass like the bark, sawdust and wood chips used for biofuel production. Such biomass types are by-products from the forest-based industry and utilising them for energy production derives further value from the forest resource.

In addition to increasing share of renewable energy, Sappi’s mills are also focused on reducing energy consumption. Sappi Kirkniemi Mill is party to Finland’s National Energy Efficiency Agreement and consistently reaches their energy saving targets. Kirkniemi’s ISO 50001 certification provides further evidence of the mill’s systematic improvement in energy efficiency.

Stahl, an active proponent of responsible chemistry, today announces that – by the end of Q2 2022 – it will extend its GHG reduction targets to cover Scope 3 emissions. This step underlines Stahl’s commitment to aligning its strategy with the 2015 Paris Climate Agreement goals, updated at the recent COP26 in Glasgow.

Between 2015 and 2020 Stahl reduced its Scope 1 and 2 (direct) GHG emissions by 37%, and has committed to a further 2% reduction each year to 2030. Scope 3 emissions cover all the indirect emissions that can occur in a company’s value chain, including raw material acquisition, transportation, and the end-of-life impact of its products. By focusing on Scope 3 emissions, Stahl is committing to de-fossilizing its supply chain and ensuring further accountability for its total environmental impact.

Michael Costello, Stahl Group ESG Director: “Only by focusing on reducing Scope 3 emissions can we accurately align our de-fossilization strategy with the global goal of limiting global average temperature increase to 1.5°C, as agreed at the 2015 Paris Climate Agreement and the COP26 in Glasgow. We look forward to working with partners across our industry and value chain to make this happen.”

Stahl, an active proponent of responsible chemistry, has taken an important step toward realizing its target of having lifecycle assessment (LCA) data for all strategic products by the end of 2023. By working closely together with Spin 360, a tech-enabled sustainability consultancy, Stahl has achieved certification of LCA data generation systems, allowing verifiable information to be collected for its products.
LCA is a methodology that measures the impact of any product on the environment over the course of its life. The LCA methodology can provide quantitative data in a format that permits comparisons to be made. The certification of LCA data generation systems is a foundational step to ensuring the accuracy and reliability of future LCA analyses.

Through close collaboration, Stahl and Spin 360 have implemented an Environmental Product Declaration (EPD) system – certified by Bureau Veritas – at Stahl’s site in Palazzolo, Italy. An EPD is an independently verified and registered document that communicates transparent and comparable information about the environment impact of products across their entire lifecycle. This implementation underlines Stahl’s commitment to enabling the sustainable development of its industry by driving accountability and transparency.

Michael Costello, Stahl Group ESG Director: “One of Stahl’s strategic ESG goals is to collect verifiable, high-quality LCA data for its products, thereby paving the way to lowering the environmental impact of the whole supply chain. This EPD system certification is an important achievement, and a key step in realizing this goal. Looking ahead, we’ll continue to work with our partners to enable our certified LCA data availability and shape a better industry.”

Federico Brugnoli, CEO of Spin 360: “We are very proud to have supported this complex process that will ensure the complete reliability of Stahl’s LCA data. Now we will look at the next steps in supporting Stahl, focusing environmental footprint reductions through science-based evolution of the industry. We’re confident that – together – we can ensure a better future for us all.”

After its launch on 20 September 2020, the RCI is proud to celebrate its first anniversary this fall. The balance sheet of the first year is impressive: starting from 11 founding members, that number increased to 30 member companies within 12 months. Numerous webinars, press releases, background information, a glossary and a comic allowed to convey the “Renewable Carbon” concept to the public. The RCI is actively working on labelling and policy analysis, and more activities will follow in the next year.

Key for this success: the topic of renewable carbon in chemicals and materials is increasingly becoming a focus of politics and industry. Larger companies will have to report their GHG emissions and also the footprint of their products as part of legislative changes surrounding the European Green Deal. In this context, indirect emissions and the carbon sources of materials will play a much more crucial role. The RCI is actively working on solutions for companies to shift from fossil to renewable carbon, which consists of the use of bio-based feedstock, CO2-based resources and recycling. In the future, reporting on GHG emissions will also include Scope 3 emissions, which are all indirect emissions that occur along the company’s value and supply chain and where the used raw materials account for a large proportion of the footprint. Here is where the carbon source of chemicals and plastics comes into play as an important contributor to the carbon footprint. Without a shift from fossil to renewable carbon feedstocks (combining bio-based, CO2-based and recycled), a sustainable future and the Paris climate targets will be almost impossible to master.

To discuss, promote and realise the shift, 30 innovative companies have already joined forces to support the transition to renewable carbon, considering both technological and economical approaches – and helping to shape the political framework accordingly.

For the second year, RCI plans to focus on a comprehensive understanding of the expected political framework conditions in Europe and across the globe, since they will determine the future of chemistry and materials more than ever. Building on this knowledge, the topic of renewable carbon could then to be systematically integrated into new political directives, which has so far not been effectively managed.

In reality, the political focus lies on the strategy of decarbonising the energy sector, a very central and Herculean task. However, it cannot be applied to the chemical and material world because carbon is usually the central building block that cannot be dispensed with. On the contrary, the demand for carbon in the chemical and materials sectors is expected to more than double by 2050. In order to meet this demand in a sustainable manner, we must move towards quitting fossil carbon. For the first time in industrial history, it is possible to decouple chemistry and materials from petrochemicals and completely cover the demand through the utilisation of biomass, CO2 and recycling.

It looks like a normal shirt, but it has it all: The new SmartTex shirt uses integrated sensors to transfer physiological data from astronauts to Earth via a wireless communication network. In this way, the effects of the space environment on the human cardiovascular system will be evaluated and documented, especially with regard to long-term manned space missions. Developed by the German Aerospace Center (DLR) in cooperation with DSI Aerospace Technology, the Medical Faculty of Bielefeld University and textile research partner Hohenstein, SmartTex will be tested for the first time as part of the Wireless Compose-2 (WICO2) project by German ESA astronaut Dr. Matthias Maurer, who will leave for his ‘Cosmic Kiss’ mission on the International Space Station (ISS) for six months on October 30, 2021.

"We were already able to gain valuable insights into the interaction of the body, clothing and climate under microgravity conditions during the previous projects Spacetex (2014) and Spacetex2 (2018)," explains Hohenstein Senior Scientific Expert Dr. Jan Beringer. The insights provided at the time by the mission of ESA astronaut Dr. Alexander Gerst have now been directly incorporated into the development of the new SmartTex shirt at Hohenstein. "Matthias Maurer can wear his tailor-made shirt comfortably on his body during his everyday work on the International Space Station. For this, we used his body measurements as the basis for our cut development and the production of the shirt. We integrated the necessary sensors as well as data processing and communication modules into the shirt's cut in such a way that they interfere as little as possible and are always positioned in the right place, regardless of the wearing situation. This is the prerequisite for reliably measuring the relevant physiological data." The SmartTex shirt is intended to provide a continuous picture of the vital functions of astronauts. This will be particularly relevant for future long-term manned space missions to the Moon and Mars.

For example, during the BEAT experiment (Ballistocardiography for Extraterrestrial Applications and long-Term missions), Matthias Maurer will be the first astronaut to wear a T-shirt equipped with sensors that measure his ballistocardiographic data such as pulse and relative blood pressure. For this purpose, the sensors were calibrated in the :envihab research facility at the DLR Institute of Aerospace Medicine in Cologne. Details on the contraction rate and opening and closing times of the heart valves, which are normally only accessible via sonography or computer tomography, can also be read from the data material. The goal is to study the effects of the space environment on the human cardiovascular system. To be able to analyse these effects realistically, Matthias Maurer's ballistocardiographic data will be recorded before, during and after his stay on the ISS. For the future, a technology transfer of the SmartTex shirt for application in the field of fitness or even in telemedicine is conceivable.

Wireless Compose-2 (WICO2)
The project was planned and prepared by the German Aerospace Center (DLR) and its cooperation partners DSI Aerospace Technology, Hohenstein and the University of Bielefeld. The wireless communication network reads sensor data and can determine the position of people and objects in space by propagation times of radio pulses. It is also available as a platform for several experiments on the ISS. The determined data is temporarily stored within the network and read out at regular intervals by the astronauts. These data packets are then transferred to Earth via the ISS link and analysed by the research teams. It can generate its own energy from artificial light sources via solar cells.

On 21st October the Managing Director of Officina+39 Andrea Venier has joined a panel discussion in the prestigious arena of the Kingpins24 Digital Show. He contributed to the discussion with his and Officina+39’s point of view on “Water Conservation”, together with Emrah Özkorkmaz from Bregla and Taimur Malik from Stylers International, with Edward Hertzman from Sourcing Journal & Rivet as moderator.

Water crisis remains one of the top issues for humanity and 90% of the world's natural disasters are related to water. Officina+39 has been working hard to rethink the way water is used throughout the denim processes: Andrea's contribution emphasized the company’s practical and consolidated experience in this field, as in recent years their main objective has been to drastically reduce water use in line with UN SDG6.

Andrea pointed out how “fashion industry is still currently deeply rooted in a linear approach: make, use, dispose.” Accordingly to Andrea and Officina+39, the fashion world is becoming aware of this reality and is trying to reinvent itself in order to decrease the use of this precious resource and its negative impacts but there is still work to do in order to redesign a better sustainable model, where circularity should represent the new sustainability: circularity not only when it comes to the materials, but also to water.

In the textile industry water is used as the vehicle for colors and chemical auxiliaries but luckily today many technologies aim at significantly reducing water consumption. Officina+39 is really focused on this target: Andrea explained that “Officina+39 has developed the AQUALESS MISSION, a process suitable for conventional machines that leads to a 75% reduction of the water typically used in denim and garment laundry processes, using a waterless technology and saving costs for producers.”

Despite the start-up cost of investing in the development of sustainable technologies may discourage some in the industry, it is about time to realize that these actions cannot be delayed and that we will increasingly hear about water scarcity, water stress and water risk.

Andrea stated: “It is necessary to develop water management strategies and systems in any company: today there is ISO 14000 related to environmental management, but I believe that governments, brands and related organisations should think about an ISO related just to water management. In this way, every company can understand how much value can be generated in the medium-term and how much money could be saved by investing in this kind of technologies. To create new standards related to water management, we must change the approach.”
