From the Sector

Archroma is bringing its most impactful planet-conscious innovations, including SuperSystems+, to ChromaTexChem 2023 in Mumbai from December 19-20.

Super Systems+ is a new set of end-to-end systems that combine processing solutions and intelligent effects for the entire textile processing workflow, from sizing to finishing. Developed for different end-use segments – from blue and colored denim to performance athletic wear, bottom weights, towels and sheeting – Super Systems+ aims to empower fashion and textile brands and mills to add value to their products while they deliver measurable environmental impact and enhance production efficiency.

Super Systems+ leverages the industry’s broadest product portfolio and authentic evidence-based data to support informed decision making. It is supported by The SafeEdge by Archroma, an online portal that gives Archroma customers and brands real-time access to product-related regulatory and compliance certifications and information, as well as the Archroma ONE WAY Impact Calculator, a process simulation and calculation tool designed and used by our textile processing experts to provide our customers and partners with an accurate estimate of the process costs, resource utilization, effluent discharge quality, and CO₂ emissions of the existing production process and of the newly evaluated system. These help them to select solutions that meet their performance requirements and deliver against significant sustainability targets.

Researchers at the ITA, the University of Bonn and Heimbach GmbH have developed a new method for removing oil spills from water surfaces in an energy-saving, cost-effective way and without the use of toxic substances. The method is made possible by a technical textile that is integrated into a floating container. A single small device can remove up to 4 liters of diesel within an hour. This corresponds to about 100 m2 of oil film on a water surface.
 
Despite the steady expansion of renewable energies, global oil production, oil consumption and the risk of oil pollution have increased steadily over the last two decades. In 2022, global oil production amounted to 4.4 billion tons! Accidents often occur during the extraction, transportation and use of oil, resulting in serious and sometimes irreversible environmental pollution and harm to humans.

There are various methods for removing this oil pollution from water surfaces. However, all methods have various shortcomings that make them difficult to use and, in particular, limit the removal of oil from inland waters.

For many technical applications, unexpected solutions come from the field of biology. Millions of years of evolution led to optimized surfaces of living organisms for their interaction with the environment. Solutions - often rather unfamiliar to materials scientists and difficult to accept. The long-time routine examination of around 20,000 different species showed that there is an almost infinite variety of structures and functionalities. Some species in particular stand out for their excellent oil adsorption properties. It was shown that, e.g., leaves of the floating fern Salvinia molesta, adsorb oil, separate it from water surfaces and transport it on their surfaces (Figure 1, see also the video of the phenomon.).

The observations inspired them to transfer the effect to technical textiles for separating oil and water. The result is a superhydrophobic spacer fabric that can be produced industrially and is therefore easily scalable.

The bio-inspired textile can be integrated into a device for oil-water separation. This entire device is called a Bionic Oil Adsorber (BOA). Figure 2: Cross-section of computer-aided (CAD) model of the Bionic Oil Adsorber. The scheme shows an oil film (red) on a water surface (light blue). In the floating cotainer(gray), the textile (orange) is fixed so that it is in contact with the oil film and the end protrudes into the container. The oil is adsorbed and transported by the BOA textile. As shown in the cross-section, it enters the contain-er, where it is released again and accumulates at the bottom of the container. See also the video regarding the oil absorption on the textile, source ITA).
 
Starting from the contamination in the form of an oil film on the water surface, the separation and collection process works according to the following steps:

• The BOA is introduced into the oil film.
• The oil is adsorbed by the textile and separated from the water at the same time.
• The oil is transported through the textile into the collection container.
• The oil drips from the textile into the collection container.
• The oil is collected until the container is emptied.

The advantage of this novel oil separation device is that no additional energy has to be applied to operate the BOA. The oil is separated from the surrounding water by the surface properties of the textile and transported through the textile driven solely by capillary forces, even against gravity. When it reaches the end of the textile in the collection container, the oil desorbs without any further external influence due to gravitational forces. With the current scale approximately 4 L of diesel can be separated from water by one device of the Bionic Oil Adsorber per hour.

• It seems unlikely that a functionalized knitted spacer textile is cheaper than a conventional nonwoven, like it is commonly used for oil sorbents. However, since it is a functional material, the costs must be related to the amount of oil removed. In this respect, if we compare the sales price of the BOA textile with the sales prices of various oil-binding nonwovens, the former is 5 to 13 times cheaper with 10 ct/L oil removed.
  Overall, the BOA device offers a cost-effective and sustainable method of oil-water separation in contrast to conventional cleaning methods due to the following advantages:
• No additional energy requirements, such as with oil skimmers, are necessary
• No toxic substances are introduced into the water body, such as with oil dispersants
• The textiles and equipment can be reused multiple times
• No waste remains inside the water body
• Inexpensive in terms of the amount of oil removed.
• The team of researchers from the ITA, the University of Bonn and Heimbach GmbH was able to prove that the novel biomimetic BOA technology is surprisingly efficient and sustainable for a self-controlled separation and automatic collection of oil films including their complete removal from the water. BOA can be asapted for open water application but also for the use in inland waters. Furthermore, it is promising, that the textile can be used in various related separation processes. The product is currently being further developed so that it can be launched on the market in 2-3 years.

Recently, OETI awarded the OEKO-TEX® STeP certification to two companies in the sector of personal protective equipment (PPE) and workwear: Ötscher - Berufskleidung Götzl GmbH, Austrian producer and wholesaler and longstanding PPE and OEKO-TEX® STANDARD 100 customer, and ALSICO MOROCCO (Cindico), a Moroccan PPE and work wear producer and part of the global Alsico Group, which has already introduced the certification for production facilities in Belgium and Laos.

OEKO-TEX® STeP stands for Sustainable Textile and Leather Production and is a certification system for production facilities in the textile and leather industry. The STeP system analyses critical areas of businesses using six modules: Chemical Management, Environmental Performance, Environmental Management, Social Responsibility, Quality Management, and Health protection and Safety at work.

For ALSICO MOROCCO (Cindico), OEKO-TEX® STeP offers the benefit of "a unified certification system and standardised audits to monitor social and ecological responsibility processes at global production locations," says Managing Director Mary Meylaers.

For the Austrian company Ötscher – Berufskleidung (workwear), Managing Director Thiemo Götzl emphasises the strengths of the certification in transparent communication with customers and stakeholders and a comprehensive overview of all aspects of the supply chain. "The certification also supports compliance with the German Supply Chain Due Diligence Act requirements through transparency and risk mitigation," says Thiemo Götzl.

ANDRITZ recently started up a new textile recycling line at Sfilacciatura Negro’s plant in Biella, Italy. Designed for processing post-consumer textile waste with automatic removal of hard parts, the tearing line supports the company’s expansion into new recycling segments.

In view of the growing demand for sustainable fibers in the re-spinning and nonwoven industries, Sfilacciatura Negro Biella decided to expand its recycling capabilities. The company has extensive experience in recycling industrial textile waste and already operates two tearing lines. Based on its long-term collaboration with ANDRITZ, it is now stepping into the recycling of post-consumer clothing waste.

The new generation recycling line ANDRITZ supplied to Sfilacciatura Negro is the result of ten years of close cooperation, trials in its technical center, and visits to customer lines in Spain and Portugal. ANDRITZ has tailored a complete line from feeding of sorted waste bales to baling of the recycled fibers. It is designed for highly efficient, energy-saving operation and features automated separation of hard points while maintaining a good material yield. An automated filtration unit is provided for airflow and dust management. Only one operator is needed to manage the entire line up to the recycled fiber baler. The baler can produce film-wrapped and tied bales with a weight of up to 350 kg.

During its first General Assembly, 18 European companies and organisations have formally joined ReHubs. They represent different segments of the circular textile value chain and share a common commitment to invest in textile recycling capacity in Europe. Additional partners are expected in the near future.

Current ReHubs partners are BASF, Boer Group, Coleo, Concordia Textiles, Decathlon, EURATEX, Gherzi Textil Organisation, Inditex, Indorama Ventures, Mango, PEPPER-i2, Purfi, Ratti, Recover, Refashion, Resortecs, Rester, RETEX.GREEN and TEXAID.

All partners will support ReHubs Executive Director, Chris Deloof, to kick start activities in the coming months. ReHubs partners will elaborate together on further steps and activities for the forthcoming work plan and the development of the European Textile Recycling Roadmap.

Chris Deloof commented: “I am delighted to see such a strong group of organisations teaming up with ReHubs. They are a great example of how to establish a new circular textile value chain in Europe. We need to focus now on rolling out ReHubs investment projects and further expanding our partners and investors network.”

To meet future demands on the amount of textile waste which needs to be collected and sorted, as well as the demand on recycling feedstock, it is necessary to match the demand and need for sorting of waste in Europe and create cost efficiency sorting capacities with larger scale and automation are necessary.

In an online session “Redefining Textile Waste Sorting: Impulses and findings for the future of next-gen sorting facilities” Texaid and partners talk about the current state of development and the challenges for the future.  Anna Pehrsson (Texaid), Gesine Köppe (ITA Augsburg GmbH) and partners present the results of a Technology Assessment conducted within The Transform Textile Waste into Feedstock Project (initiated by TEXAID within the ReHubs initiative) to assess the best available sorting techniques and process.

Sustainable fashion and sportswear must be high on the political agenda:
Three University of Manchester academics who specialise in fashion and textiles have criticised the Government for failing to take action to boost sustainability in the UK fashion and sportswear industries.

In an article published by the University’s policy engagement unit Policy@Manchester to coincide with the 20th annual Recycle Week, Lindsay Pressdee, Dr Amy Benstead and Dr Jo Conlon highlight that, of the one million tonnes of textiles disposed of every year in this country, 300,000 tonnes end up in landfill or incineration with figures suggesting 10 per cent of global CO2 emissions may come from the fashion industry.

And they warn that the damage inflicted by discarded sportswear is often overlooked, “despite an over-reliance on polyester garments, which are harmful to the environment as the fabric releases microfibres and takes hundreds of years to fully biodegrade.”

Pressdee, Benstead and Conlon stress the importance of establishing “sustainable behaviour throughout the supply chain” and praise the European Commission for proposing an “extended producer responsibility (EPR)” for textiles in the EU which “aims to create appropriate incentives to encourage producers to design products that have a reduced environmental impact at the end of their life.”

This contrasts with the UK where, they argue, “tackling sustainability in the fashion industry has lost its place on the political agenda.”

"We are calling on the Government to reintroduce textiles as part of the school curriculum to engage young people in sustainable materials and equip them with the basic skills required to repair clothes.”
Lindsay Pressdee, Dr Amy Benstead and Dr Jo Conlon

The University of Manchester academics contend that there has been “disappointing lack of progress from the UK Government” following the House of Commons Environmental Audit Committee’s Fixing Fashion report in 2019.

They continue: “This report included a call for the use of EPR as well as other important recommendations such as a ban on incinerating or landfilling unsold stock that can be reused or recycled and a tax system that shifts the balance of incentives in favour of reuse, repair and recycling to support responsible companies. We urge the Government to think again and drive forward the Committee’s recommendations in order to put sustainable fashion back on the political agenda.”

Pressdee, Benstead and Conlon also criticise Ministers for abolishing the standalone GCSE in textiles which provided many young people with the ability to mend clothing such as football kits instead of throwing them away.

They write: “We are therefore calling on the Government to reintroduce textiles as part of the school curriculum to engage young people in sustainable materials and equip them with the basic skills required to repair clothes.”

The University of Manchester has launched a new project dedicated to tackling the impact of textile waste in the football industry through the provision of workshops tasked with transforming surplus football shirts into unique reusable tote bags, whilst educating local communities on the environmental impacts of textile waste and how to extend the life of garments. The initiative aims to provide a fun, responsible way to keep kits in circulation while shining a light on the problem.

HeiQ AeoniQ™ becomes an active brand partner of the Canopy initiative with eleven other companies to address the growing climate and biodiversity crises by committing to keep Ancient and Endangered Forests out of our man-made cellulosic fiber supply chain.

The commitments that HeiQ AeoniQ™ is making are part of solutions-driven non-profit Canopy’s Pack4Good and CanopyStyle initiatives which currently represent collectively 950 brand partners. Together, the initiatives are shifting supply chains away from vital forests to low-impact, circular Next Gen Solutions.

“We must rapidly replace oil-based polyester in the textile industry causing microplastics, global warming, landfill and ecosystem degradation. Cellulose is the most abundant biopolymer in the world and is best suited to replace polyester. However, we must pay attention to cellulose feedstock sources. Our forests, a potential cellulose feedstock, are one of the most important solutions to addressing the effects of climate change. Approximately 2.6 billion tons of carbon dioxide, one-third of the CO₂ released from burning fossil fuels, is absorbed by forests every year. Around 12.5% of global greenhouse gas emissions (5-10 GtCO₂e annually) come from deforestation. We are losing forests at an alarming rate. Every year, around 10 million hectares of forests globally are destroyed. We need immediate action to increase forests again. Canopy is our go-to partner to replace polyester with circular & sustainable cellulose feedstock for our innovative HeiQ AeoniQ™ fiber revolution.” said Carlo Centonze, HeiQ Group CEO.

Paper packaging is also a key driver of forest loss globally, as 3.1 billion trees are cut down annually to produce the boxes and bags in which products are packaged and shipped. Paper packaging production has increased by 65% over the past two years.

“The range of companies and sectors represented in today’s announcement reflects the breadth of market response to the growing climate and biodiversity crises and intensifying supply chain disruptions,” said Nicole Rycroft, Founder and Executive Director of Canopy. “Today’s brand partners add significant momentum to global conservation efforts and the movement to transform ‘take, make, waste’ supply chains to be lower-impact and Next Gen.”

Today, as part of Pack4Good, HeiQ AeoniQ™ committed to:

• Eliminate Ancient and Endangered Forests from our paper packaging supply chain.
• Reduce material use through design innovation.
• Maximize recycled content.
• Explore and scale alternative Next Gen fibers (such as agricultural residues).
• Where virgin fiber is necessary, use FSC-certified fiber.

• Lenzing and Södra – a long-standing partnership for systemic change
• International Textile Manufacturers Federation (ITMF) honored the two companies in the "International Cooperation" category
• EU co-funded recycling project for textiles on an industrial scale

The Lenzing Group, the world’s leading supplier of specialty fibers for the textile and nonwovens industries, and the Swedish pulp producer Södra have received the ITMF Award 2023 in the category “International Cooperation” for their joint achievements in textile recycling and circular economy. The award was presented at the ITMF Annual Conference in Keqiao, China, on November 06, 2023.

The ITMF Award 2023 is given by the International Textile Manufacturers Federation (ITMF) to recognize outstanding achievements and merits in the textile sector in two categories: ”Sustainability & Innovation“ and ”International Cooperation“. Since 2021, the two pioneers have been joining forces in textile recycling, making a decisive contribution to promoting the circular economy in the fashion industry. As part of the cooperation, the companies intend to share their knowledge with each other and jointly develop processes to enable the wider use of cellulose-based used textiles on a commercial scale.

The OnceMore® pulp from Södra, which was jointly developed further by Södra and Lenzing, is subsequently used, among other things, as a raw material for the production of Lenzing fibers with REFIBRA™ technology. The OnceMore® process makes it possible to process and recycle a blend of cotton and polyester.

ITMF paid particular tribute to the joint LIFE TREATS project (Textile Recycling in Europe AT Scale)¹,which was supported by an EU grant of EUR 10m under the LIFE 2022² program and aims to build a large-scale plant at Södra's Mörrum site in Sweden.
