From the Sector

The substance graphene can become increasingly important as a component in textile catalysts when purifying water from textile dyeing as has been shown in a recently completed doctoral project at the University of Borås.

In his project, Milad Asadi, a new doctor in Textile Technology, has modified conventional yarn by encapsulating iron particles in graphene and developed a multifunctional smart e-textile. The focus was on developing a method for purifying wastewater from textile dyeing. The smart e-textile acts as a catalyst that causes the substance hydrogen peroxide to be formed, which is needed in order to break down pollutants in wastewater.

The project has generated a complete textile reactor for the treatment of wastewater through the so-called electro-Fenton technology, which is mainly used industrially to purify wastewater. The novelty of the technology is to use the properties of both graphene and iron, which is the main catalyst.

“Previous research has mainly been about the treatment of wastewater by using chemicals to break down the textile dyes. My project is the first where graphene, which is electrically conductive, is used to encapsulate iron. The e-textile can also be used several times, unlike when chemicals are used and which are then rinsed off. The challenge in the project was to scale up the technology so that the treated yarn can be fed into automatic knitting machines”, explained Milad Asadi.

The e-textile catalyst can be reused and hydrogen peroxide is formed internally inside the reactor, which reduces the use of biological catalysts, making the technology more sustainable compared to chemical methods.

• Aims to tackle the immense textile waste generated in urban environments, on the back of import bans of waste materials
• Addresses the shortcomings of current textile recycling technologies, which are unsuitable for urban settings due to the use of heavy chemicals
• Technologies developed by the newly-formed RGE-NTU Sustainable Textile Research Centre will be test-bedded in RGE’s pilot urban-fit textile recycling plant, projected for completion as early as 2024

Royal Golden Eagle (“RGE”), a global group of resource-based manufacturing companies, which includes a world-leading viscose fibre producers Sateri and Asia Pacific Rayon (APR), is developing urban-fit, closed-loop textile-to-textile recycling solutions, through the newly-formed RGE-NTU Sustainable Textile Research Centre (RGE-NTU SusTex). This is a five-year research collaboration between RGE and Nanyang Technological University, Singapore (“NTU”), to accelerate innovation in textile recycling that can be deployed in urban settings. The research centre will develop new technologies to recycle textile waste into fibre and create new, next-generation eco-friendly and sustainable textiles.

This move comes on the back of the tightening of waste import bans in countries such as China, India and Indonesia, which are among the world’s largest waste processors. The stricter import bans have left cities in need of viable local textile recycling solutions to tackle the immense textile waste generated.

RGE Executive Director, Mr Perry Lim, said, “Current textile recycling technologies, which rely primarily on a bleaching and separation process using heavy chemicals, cannot be implemented due to environmental laws. At the same time, there is an urgent need to keep textiles out of the brimming landfills.” He added, “As the world’s largest viscose producer, we aim to catalyse closed-loop, textile-to-textile recycling by developing optimal urban-fit solutions that can bring the world closer to a circular textile economy.”

Globally, an estimated 90 million tonnes of textile waste is generated and disposed of every year, with less than 1% being upcycled into new clothing or other textile materials. By 2030, the amount of global textile waste, which currently accounts for almost 10% of municipal solid waste, is expected to reach more than 134 million tonnes. The textile industry is also responsible for 10% of global greenhouse gas emissions – more than international flights and maritime shipping combined.

At present, most of the available textile recycling technologies are open-loop, where textile waste is typically downcycled to lower-quality products (insulating materials, cleaning cloths, etc.) or be used in waste-to-heat recycling.

“Closed-loop textile-to-textile recycling processes, particularly chemical recycling, are still under development. Scaling up the technologies to industrial scale remains a challenge. A key bottleneck is that refabricating textile waste into fibre needs purity standards for feedstock. However, most of the clothes that we wear are made of a mixture of different synthetic and natural fibres, which makes separating the complex blends of materials challenging for effective recycling.

“Our aim is to address this industry pain point by developing viable solutions that use less energy, fewer chemicals and produces harmless and less effluents, and then potentially scale up across our global operations,” Mr Lim said.

To tackle the key challenges in closed-loop textile recycling, RGE-NTU SusTex is looking into four key research areas, namely cleaner and more energy efficient methods of recycling into new raw materials, automated sorting of textile waste, eco-friendly dye removal, and development of a new class of sustainable textiles that is durable for wear and, at the same time, lends itself to easier recycling.

Technologies developed by RGE-NTU SusTex will be test bedded at RGE’s pilot urban-fit textile recycling plant in Singapore, which is projected for completion as early as 2024. If successful, RGE has plans to replicate the plant in other urban cities within its footprint.

The world’s largest fashion brands and retailers must increase transparency to tackle the climate crisis and social inequality, according to the latest Fashion Transparency Index.

The seventh edition of the Fashion Transparency Index ranks 250 of the world’s largest fashion brands and retailers based on their public disclosure of human rights and environmental policies, practices, and impacts, across their operations and supply chains.

• Brands achieved an average score of just 24%, with nearly a third of brands scoring less than 10%
• The majority of brands (85%) do not disclose their annual production volumes despite mounting evidence of clothing waste around the world
• Most major brands and retailers (96%) do not publish the number of workers in their supply chain paid a living wage

The Index reveals insights into the most pressing issues facing the fashion industry, like:

• As new and proposed legislation focuses on greenwashing claims, almost half of major brands (45%) publish targets on sustainable materials yet only 37% provide information on what constitutes a sustainable material.
• Only 24% of major brands disclose how they minimise the impacts of microfibres despite textiles being the largest source of microplastics in the ocean.
• The vast majority of major brands and retailers (94%) do not disclose the number of workers in their supply chains who are paying recruitment fees. This paints an unclear picture of the risks of forced labour as workers may be getting into crippling debt to accept jobs paying poverty wages.
• While many brands use their channels to talk about social justice, they need to go beyond lip service. Just 8% of brands publish their actions on racial and ethnic equality in their supply chains.

Despite these results, Fashion Revolution is encouraged by increasing supply chain transparency among many major brands, primarily with first-tier manufacturers where the final stage of production occurs, e.g. cutting, sewing, finishing and packing. Nine brands have disclosed their first-tier manufacturers for the first time this year. It is encouraging to see significant progress across market segments including luxury, sportswear, footwear and accessories and across different geographies.

Fashion Revolution’s co-founder and Global Operations Director Carry Somers says: “In 2016, only 5 out of 40 major brands (12.5%) disclosed their suppliers. Seven years later, 121 out of 250 major brands (48%) disclose their suppliers. This clearly demonstrates how the Index incentivises transparency but it also shows that brands really are listening to the millions of people around the world who keep asking them #WhoMadeMyClothes? Our power is in our persistence.”

More key findings from the Fashion Transparency Index 2022:

Progress on transparency in the global fashion industry is still too slow among 250 of the world’s largest fashion brands and retailers, with brands achieving an overall average score of just 24%, up 1% from last year
For another year, the initiative has seen major brands and retailers publicly disclose the most information about their policies, commitments and processes on human rights and environmental topics and significantly less about the results, outcomes and impacts of their efforts.

Most (85%) major brands still do not disclose their annual production volumes despite mounting evidence of overproduction and clothing waste
Thousands of tonnes of clothing waste are found globally. However, brands have disclosed more information about the circular solutions they are developing (28%) than on the actual volumes of pre- (10%) and post-production waste they produce (8%). Brands have sat by as waste importing countries foot the bill, resulting in serious human rights and environmental implications.

Just 11% of brands publish a responsible purchasing code of conduct indicating that most are still reluctant to disclose how their purchasing practices could be affecting suppliers and workers
Greater transparency on how brands interact with their suppliers ought to be a first step towards eliminating harmful practices and promoting fair purchasing practices. The poor performance on transparency in this vital area is a missed opportunity for brands to demonstrate they are serious about addressing the root causes of harmful working conditions, including the instances where they themselves are the key driver.

Despite the urgency of the climate crisis, less than a third of major brands disclose a decarbonisation target covering their entire supply chain which is verified by the Science-Based Targets Initiative
Many brands and retailers rely heavily on garment producing countries that are vulnerable to the impacts of the climate crisis, yet our research shows that only 29% of major brands and retailers publish a decarbonisation target covering their operations and supply chain which is verified by the Science Based Targets Initiative.

Only 11% of brands publish their supplier wastewater test results, despite the textile industry being a leading contributor to water pollution
The fashion industry is a major contributor to water pollution and one of the most water intensive industries on the planet. Only 11% of major brands publish their wastewater test result, and only 25% of brands disclose the process of conducting water-related risk assessments in their supply chain. Transparency on wastewater test results is key to ensuring that brands are held accountable for their potentially devastating impacts on local biodiversity, garment workers and their communities.

Most major brands and retailers (96%) do not publish the number of workers in their supply chain paid a living wage nor do they disclose if they isolate labour costs
Insufficient progress is being made by most brands towards ensuring that the workers in their supply chain are paid enough to cover their basic needs and put aside some discretionary income. Just 27% of brands disclose their approach to achieving living wages for supply chain workers and 96% do not publish the number of workers in their supply chain paid a living wage. In response, we have joined forces with allies across civil society to launch Good Clothes, Fair Pay. The campaign demands groundbreaking living wage legislation across the garment, textile and footwear sector.

Bodyshops can now take advantage of the vehicle refinish industry’s first repair calculator to measure, manage and reduce carbon emissions, which has been developed by AkzoNobel.

Designed to help customers improve their carbon footprint when using the company’s premium refinish products, the CO₂eRepairCalculator* is part of a new initiative which aims to encourage bodyshops to become more sustainable.

The tool is the latest digital innovation from AkzoNobel focused on making a long-lasting difference to customers. It identifies the carbon levels associated with the painting and drying process – including the energy consumed – and is linked directly to the vehicle refinishing products being used. It also provides data relating to the emission of volatile organic compounds (VOCs), therefore helping customers to understand where improvements can be made.

When using the tool, the emissions and energy consumed are calculated based on a controlled two-panel repair in a spray booth to Greenhouse Gas Protocol accounting standards. The results are presented in an online dashboard, which allows local energy prices to be factored in.

The launch means it will now be easier for bodyshops to take positive action in an effort to meet their sustainability and carbon reduction targets. This is becoming increasingly important, as insurance companies are putting greater pressure on preferred bodyshop partners to cut their emissions in line with supply chain ambitions that meet the UN Sustainable Development Goals.

The CO₂eRepairCalculator is currently being introduced in the UK market to Sikkens customers (with Lesonal to follow shortly). It will be rolled out across markets in Europe during the next few months.

*CO₂e stands for carbon dioxide and equivalent gases. The tool measures carbon dioxide (CO₂) and equivalent gases such as methane (CH₄) and nitrous oxide (N₂O), which all fall under the term greenhouse gases (GHGs).

The electrolyser producer Enapter has set itself the goal of developing its entire production process to run without negative impacts on the environment. As an important step on this journey, it is building the Enapter Campus production facility, which will be powered entirely from renewable energy produced on-site and in the neighbouring Bioenergiepark. The site in in Saerbeck, North Rhine-Westphalia combines electrolyser production, an R&D building, administration and office space, as well as a cantine over 82,000 square metres. Now the company wants to investigate what other measures can be implemented to achieve its “Life Cycle Impact Zero” aspirations – together with researchers from Fraunhofer UMSICHT, the Wuppertal Institute and the Institute of Sustainable Nutrition (iSuN) of FH Münster.

With the Life Cycle Impact Zero project, started on April 15, 2022, the parties want to develop and apply an especially comprehensive and holistic approach to environmental assessment. This includes chemical manufacturing and electrolyser production, as well as matters like the use of energy and water resources, the generation of waste or the human factor in general. This is intended to cover all interactions between business and people. That includes, in particular, Enapter’s employees, but also people in upstream and downstream value chains, users of the technology or residents close to the production site. A concept for sustainable employee catering is also being developed.

The basis for all environmental assessment that will be carried out is ISO 14040. The recognised international standard divides the research into four phases: Aim and scope of the study, inventory analaysis, impact assessment, as well as interpretation. Sensitivity analyses and scenario techniques are also used as further methods.

On the basis of these analyses, the 18-month project should derive concrete measures to avoid negative environmental impacts completely, if possible, for example in production, employee mobility or in energy supply. Furthermore, it will examine whether these measures are transferable to Enapter’s other locations – such as in Italy. Following on from the project, the steps defined should be implemented by Enapter in the next phase. In the subsequent Phase 3, a renewed analysis is planned. This will determine if the technological innovations achieved by then in the production and use of Enapter’s electrolysers can enable additional ecological improvements.

The Life Cycle Impact Zero project is supported by the State of NRW.

• The Borvida™ portfolio introduces sustainable base chemicals to Borealis’ range of product offering
• The range will initially be based on non-food waste biomass, and chemically-recycled waste; in the future it will also draw from atmospheric carbon capture
• The traceability of the content will be based on Mass Balance, which is ISCC PLUS certified
• This is the next step in an ambitious sustainability journey, which will see Borealis move away from traditional fossil-based feed

Borealis is strengthening its EverMinds™ circular product offering with Borvida™, a range of sustainable base chemicals.

The Borvida portfolio will offer base chemicals or cracker products (such as ethylene, propylene, butene and phenol) with ISCC Plus-certified sustainable content from Borealis sites in Finland, Sweden and Belgium. The move is part of Borealis’ broader commitment to a Future-Positive Revolution, in which the unrivalled benefits of base chemicals and polymers can be enjoyed at minimal impact to the planet.   

The portfolio will initially comprise Borvida B, from non-food waste biomass, and Borvida C, from chemically-recycled waste. In the future, the range will evolve to include Borvida A, sourced from atmospheric carbon capture. Borvida is complementary and is the building block to Bornewables™, a portfolio of polyolefins based on renewably-sourced second generation feedstocks, and Borcycle™, which offers circular polyolefins produced from mechanically- and chemically-recycled plastic waste.

Borealis produces a wide range of base chemicals for use in numerous industries based on various feedstock, such as naphtha, butane, propane and ethane. Through its olefin units (steam cracker and propane dehydrogenation), it converts these into the building blocks of the chemical industry: ethylene, propylene and C4 hydrocarbons (butylenes, ethyl tertiary-butyl ether (ETBE) and butadiene), and C5-6 hydrocarbons (pygas, phenol) among others.

The basis of the Borvida portfolio is Mass Balance, a Chain of Custody model that enables sustainable content to be tracked, traced, and verified through the entire value chain, offering sustainability-assured products from feedstock to end product. Using this model, circular alternatives can be offered in a cost-effective and environmentally-conscious way, which can be scaled up quickly without compromising on quality or efficiency.

Borvida can be used for a wide range of different polymer and chemical applications, also beyond polyolefins (PO). Non-PO polymers, such as polycarbonates, acrylonitrile butadiene styrene (ABS), super absorbant polymer (SAP) and other chemicals, are utilised for various end applications including coatings, plasticizers, adhesives, automotive, electronics, lubricants, detergents, appliances and sports equipment.

Together with key strategic partners, including Neste and Covestro, Borealis strives to provide a long-term solution in order to allow value-chain partners to meet their sustainability goals. Borvida will enable our customers to increase the sustainability of their products, keeping them ahead of forthcoming legislative changes, and meeting their customers’ demands for climate-conscious products.

Introduced on a smaller scale in early 2020, early renewable base chemicals customers include Covestro. “The use of alternative sustainable raw materials is one important pillar of our strategic ambition to become fully circular”, comments Frank Dörner, Managing Director Covestro Procurement Services GmbH & Co. KG. “The new product line is a good example for joint solutions, another strategic pillar, in order to establish new and reliable supply chains creating benefits for our customers.”

• Biotransformation technology for nonwovens

Avgol^® has received the prestigious Innovation Award at the RIGHT Hygiene conference in recognition of its collaboration with Polymateria in development of pioneering biotransformation technology for nonwovens.
 
Biotransformation is a unique functionality wherein a conventional nonwoven fabric can be modified to react to certain triggers to then begin a cascade, and importantly a fundamental chemical transformation of the polymer resin into a wax that is readily degraded by natural bacteria, microbes and fungi normally found in the environment.
 
“The transformation is triggered through the combined effects of the natural elements of decay - air, moisture, heat and sunlight,” said Mr. Sanjay Bhayani, Director of India Operations with Avgol. “Once triggered, the material will transform into a low molecular weight wax structure leaving no microplastics or toxic residue behind. Moreover, if the product comprising the biotransformation technology is disposed of in the normal way and facilities are available, then it can be recycled by readily available means.”

“By bringing the Biotransformation technology to the various potential markets in India, we hope to offer a real-world solution to waste management,” he said. “We particularly hope to address aspects of the creation of fugitive waste and remove this from the environment without causing additional, and potentially more dangerous, problems.”

With the purchase of the latest technology, iSAVER® by Itema, in weaving machines, ISKO pushes the envelope of technological performance and sustainability, making further progress in product and process efficiency.

This decision is an additional, important asset in ISKO’s journey towards a genuine Responsible Innovation™. It is part of other crucial investments made by the company, aimed at further reducing its environmental impact, among which stand out R-TWO™50+ – a new denim generation made with a minimum of 50% pre- and post-consumer recycled blend – and the Green Machine – a pioneering technology providing a 100% post-consumer recycling solution that fully separates and recycles cotton and polyester blends at scale.

After an intensive process, a selection was made where ISKO focuses on the development of technical solutions that enable greater resource savings and more sustainable production methods, always with the protection of workers at heart.

As a result, ISKO’s Headquarters extend the company's long-term relationship with Itema,
strengthening the company’s position as the mill with one of the world’s largest denim capacities. The new rapier machines are enhanced by the iSAVER® technology, a breakthrough mechatronic innovation that eliminates the waste selvedge on the left side of the fabric, allowing for saving in energy and raw materials, cutting in half the cotton waste that typically results from the weft yarn. All types of ISKO’s innovative fabrics, with a multitude of different constructions and fiber mixtures, can now be produced using these advanced weaving technologies, with a special focus given to the R-TWO™ technology in terms of its sustainable credentials.

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.
