Nordic cooperation on circular innovation focusing on workwear

The University of Borås, Aalborg University Business School and Circular Innovation Lab have just started the 'North-South Circular Value Chains Within Textiles' project - an explorative project that aims at bridging textile brands in the Nordics with a strong focus on sustainability with innovative producers in the South.

Focus areas are Circular Value Chains (CVCs), Circular and resource-efficient textiles economy, Workwear and technical clothing, Sectors such as construction, energy, electronics and IT, plastics, textiles, retail and metals.

Made possible by a grant from the Interreg ÖKS programme, the first step is to create a specific economic, legal and technological framework allowing Scandinavian workwear companies to enter into close collaboration on circular solutions in the overall textile value chain and to prepare, and adapt their global value chains to the upcoming EU regulations on circular economy.

The University of Borås, Aalborg University Business School and Circular Innovation Lab have just started the 'North-South Circular Value Chains Within Textiles' project - an explorative project that aims at bridging textile brands in the Nordics with a strong focus on sustainability with innovative producers in the South.

Made possible by a grant from the Interreg ÖKS programme, the first step is to create a specific economic, legal and technological framework allowing Scandinavian workwear companies to enter into close collaboration on circular solutions in the overall textile value chain and to prepare, and adapt their global value chains to the upcoming EU regulations on circular economy.

Recently, the consortium partners convened for an initial meeting at The Swedish School of Textiles to discuss the project framework, which is a feasibility study intended to lead to a multi-year project involving workwear companies in the Öresund-Kattegat-Skagerrak (ÖKS) region, including their supply chains in Asia.

Kim Hjerrild, Strategic Partnerships Lead at the Danish think tank Circular Innovation Lab, Copenhagen, explained: "The goal is to assist workwear producers in Denmark, Sweden, and Norway in becoming more sustainable through circular product design, production, and service concepts. We are pleased to have The Swedish School of Textiles lead the project as they have a strong tradition of collaborating with textile companies."

Complex branch
The decision to focus specifically on workwear stems from it being a complex part of the textile industry, demanding strict standards, certifications, safety aspects, and specific functions depending on the application area, such as specific high-performance environments, healthcare, and hospitality. "To future-proof their operations, companies need to become more resource efficient and circular by producing durable and long lasting workwear that can be repaired and reused. Additionally, they must reduce their carbon footprint per product, as well as minimize problematic chemical usage, and increasingly use recycled materials" explained Kim Hjerrild.

Wants to provide companies with tools and knowledge
Apoorva Arya, founder and CEO of Circular Innovation Lab, elaborates: "Our first and primary goal is to equip Scandinavian workwear companies with tools and knowledge in order to comply with the upcoming EU directives and policies. This includes regulations on product-specific design requirements to labour conditions for employees, human rights, all the way from production to third-party suppliers. Ensuring these companies, especially their suppliers, can transition to a circular supply chain, and navigate the legislative landscape, while guaranteeing competitiveness in the global market."

Focus on new structures
Rudrajeet Pal, Professor of Textile Management at The Swedish School of Textiles, is pleased that the university can be the coordinator of the project. "From the perspective of my research group, this
is incredibly interesting given the focus on the examination and development of ‘new’ supply chain and business model structures that would enable sustainable value generation in textile enterprises, industry, and for the environment and society at large. We have conducted several projects where such global north-south value chain focus is eminent, and this time particularly in workwear companies’ value chain between Scandinavia and Asia. We are delighted to contribute expertise and our experience of working internationally."

About the pre-project North-South Circular Value Chains Within Textiles, NSCirTex
The project aims to support the circular transition in the Nordics by setting up a shared governance model to enable pre-competitive collaboration and the design of circular value chains between Scandinavian workwear companies in the ÖKS-region and producers in India, Bangladesh, Vietnam, and Türkiye.

The next step is to achieve a multi-year main project where workwear companies with their suppliers in Asian countries, can test tailored models for shared governance as a way to develop practical circular solutions, such as post-consumer recycling, circular material procurement, develop safe and resource efficient circular products, enhance social sustainability and due diligence, among others. The main project will thus develop solutions to reduce material footprint, and resource usage while generating both commercial viability and prepare for new regulation, reporting, and accountability.

Partners in this feasibility study: University of Borås, Aalborg University Business School, and Circular Innovation Lab. The feasibility study is funded by the EU through the Interreg Öresund-Kattegat-Skagerrak European Regional Development Fund.

Aerogel: Frozen Smoke for Clothing and Work Safety

Comprised of up to 99.8 percent air, aerogel is the lightest solid in the world. The material, which is also called “frozen smoke” due to its appearance and physical properties, exhibits extremely low heat conductivity which exceeds other insulations many times over. This is why NASA has already been using aerogel for aerospace projects for many years.

Despite this, it has not been possible to bind the material to textiles in a high concentration and enable straightforward further processing over the roughly 90-year history of the material. Outlast Technologies GmbH has developed an innovative process - a patent has already been filed for -  for permanently adhering large amounts of aerogel to different media, like nonwoven fabric, felt and composites materials. Their original properties are retained throughout, so they can easily be further processed using conventional production methods.

Outlast Technologies GmbH has developed an innovative process - a patent has already been filed for -  for permanently adhering large amounts of aerogel to different media, like nonwoven fabric, felt and composites materials. Their original properties are retained throughout, so they can easily be further processed using conventional production methods.

The fabrics sold under the Aersulate name are only 1 to 3 mm thick and achieve very high insulation values which are largely retained even under pressure and in moist conditions. Despite their high performance, they are still soft and can be used for shoes, clothing and work safety products, as well as for sleeping bags and technical applications.
 
“Thanks to its extraordinary physical properties, NASA has already been using aerogel for many years,” remarked Volker Schuster, Head of Research and Development at Outlast Technologies. “For example, for the insulation of its Mars rovers and for capturing dust from the tail of a comet during the Stardust mission,” he continued. Since the development of aerogel by American scientist and chemical engineer Samuel Stephens Kistler in 1931, no-one had been able to apply the versatile material to textiles in large amounts without changing their original properties, despite intensive research. This means that the products were often not only very rigid, but made processing with conventional production methods impossible due to their high degree of dust abrasion. With the newly developed Aersulate technology, which was presented for the first time in June 2022, the Heidenheim-based specialist for textile thermoregulation is opening a different chapter in insulation history.

High-performance insulation just 1 to 3 mm thick
“The consistency of aerogel can be best described as liquid dust particles which spread uncontrollably throughout a room within seconds thanks to their minimal thickness,” explained Schuster. “This is why processing is a big challenge.” Outlast Technologies has managed, after a development period of around five years, to bring an innovative process involving the adhering of aerogel between multiple layers of material to market maturity. Depending on the area of application, nonwoven fabric, felt and different composite materials can be used as the media. What is special here is that the properties of the respective textiles are not adversely affected by the Aersulate technology, meaning that they can easily be further processed with conventional means and under industrial conditions despite their acquired thermal properties.
 
As a silicate-based solid, aerogel is obtained from natural quartz sand, yet exhibits a density over 1,000 times lower than glass manufactured from the same raw material. The extraordinary thermo-insulating properties of the material are thanks to its extremely porous structure, which enables it to be composed of up to 99.8 percent air.
 
“One liter of aerogel weighs just 50 g,” explained Schuster. “Just 10 g of the material has the same surface area as a soccer field, though.” Thanks to these properties, Aersulate textiles exceed all other previously known insulation materials in terms of performance, despite the fact that they are only 1 to 3 mm thick. Tests carried out by the German Institute for Textile and Fiber Research in Denkendorf (DITF) using the Alambeta method showed that the thermal resistance of an Aersulate fleece is more than double that of a conventional fleece of the same thickness. Add to this the fact that the thermo-insulating properties of Aersulate products remain high despite pressure and wetness, while they decrease enormously with other conventional materials like felt and polyurethane foam (PU) under these conditions.

Work safety and functional clothing with Aersulate
Thanks to the textile medium, thin Aersulate products are especially suitable for the shoe and clothing industry, as well as all areas of work safety. The user benefits from different properties, depending on the intended use. “With a glove made of Aersulate just 1 mm thick, you can put your hand into boiling water without being scalded, for example,” explained Schuster. “The material’s extremely hydrophobic properties play quite literally into our hands here.” In the case of knee patches on work and functional pants, as well as shoes and soles, on the other hand, the material properties also become relevant when compression occurs. This is because the thermo-insulation properties of other materials would be reduced little by little due to moisture from the outside and sweat from the inside on the one hand, and by the continual influence of body weight on the other.
          
In addition to the human body, luggage and technical devices can also be protected from extreme temperatures and the effects of weather with Aersulate. For this purpose, corresponding cell phone or equipment pockets could be sewn into garments, for example, to maintain their battery life even at very cold outside temperatures and to safeguard the devices from overheating in case of high heat exposure. “With the broad range of possible textile medium materials, Aersulate is suitable for all applications requiring high thermal resistance on the one hand, where only a little space is available and both compression and moisture can be expected on the other,” said Schuster in summary.

A+A 2017 sets New Standards for Health and Safety at Work

People matter – now more than ever. This is underscored by the huge interest taken by exhibitors in the run-up to A+A 2017, once again allowing the world’s leading trade fair for safety, security and health at work held from 17 to 20 October to post top marks. A total of 1,930 exhibitors from 63 nations and over 67,000 trade visitors came to the world’s largest trade fair for this industry in Düsseldorf. This means that this year A+A – together with the International Congress for Occupational Safety and Occupational Medicine – very much underlined the huge importance of health and safety at the workplace.

People matter – now more than ever. This is underscored by the huge interest taken by exhibitors in the run-up to A+A 2017, once again allowing the world’s leading trade fair for safety, security and health at work held from 17 to 20 October to post top marks. A total of 1,930 exhibitors from 63 nations and over 67,000 trade visitors came to the world’s largest trade fair for this industry in Düsseldorf. This means that this year A+A – together with the International Congress for Occupational Safety and Occupational Medicine – very much underlined the huge importance of health and safety at the workplace.

Investing in the health of employees pays off. It helps to ensure the performance of the workforce and increase productivity. It is all the more important to foster a holistic approach to prevention that takes all aspects of occupational health management, safety and workplace design into consideration. “Here the A+A, as the world’s leading trade fair for safety and healthy, joins forces with its partners,” sums up Messe Düsseldorf Managing Director Joachim Schäfer. “Digitalisation is no longer just something for the future and has now penetrated virtually all areas of life and work – likewise the Internet of Things that now networks billions of things together worldwide. It is fabulous that A+A is not just a stage for new technologies but is now also being seen globally as a bridgehead between the past and the future of our world of work.”

Bigger and More International than Ever: Top Marks across all Disciplines
Organisers and exhibitors alike were satisfied with how A+A 2017 went. The 31st edition of A+A held from 17 to 20 October attracted more than 67,000 trade visitors (2015: 65,000) to Düsseldorf who gathered information from the 1,931 exhibitors from 63 nations on the latest trends in the fields of occupational safety, promotion of health at work and security management in nine trade fair halls occupying for the first time 70,733 m2. At 40% the proportion of international visitors who came from over 100 nations also exceeded the share recorded at the previous event. “A+A is continually growing and underlines at all levels its relevance for the sector as the world’s leading trade fair and congress event,” says Messe Düsseldorf Managing Director Joachim Schäfer delighting at the excellent mood over the past four days and summing up talks with exhibitors and international delegations as follows: “We are proud to have been able to send out across the entire world strong signals to the markets and key impulses for political debate.” Against this backdrop the new look of A+A and the focus on what matters not just in the world of work have proven their worth: people.

Platform for Innovations and Investment
"People matter – what an apt statement,” sums up Klaus Bornack, President of the Trade Fair Advisory Board and Managing Director of Bornack GmbH & Co. KG. “A great A+A once again moved the sector with many innovative products, even more exhibitors from all specialist fields and, in turn, a rising number of very interested trade visitors from home and abroad with specific technical queries and a great deal of interest. This is confirmation that PPE is a growth market and that A+A is a leading international marketplace for safety at work.”

No. 1 International Event for Workwear  
The good investment climate as well as the interest from trade visitors in high-quality personal protective equipment and protective workwear was confirmed by a current study conducted on the German market for personal protective equipment that was published during A+A 2017 by market research firm macrom. This study showed that the volume of the entire German PPE market grew between 2014 and 2016 by 9.2% to a total of Euro 1.97b. Leading here with the largest market share is protective workwear that is increasingly also being worn in the private sphere. Commenting on this Birgit Horn, Director A+A 2017, said: “While protective workwear in the past was generally uncomfortable and not particularly fashionable, staff today are fairly willing to show themselves in public wearing this clothing. Thanks to the development of high-tech  clothing in the sports and outdoor sectors people no longer have to deprive themselves of top design and optimum performance. This was also confirmed by the over 200 Corporate Fashion exhibitors and rounded off by newly designed fashion shows.

The Future of Work is Now  
From smart skin sensors and the measuring of vital parameters to backfriendly exoskeletons and smart fleet management, data glasses and sensor-controlled fall protection: the future of work is now. This was made clear not just by the new A+A Highlight Route. Across the halls renowned exhibitors like 3M, BORNACK, Honeywell, Uvex or the Institute for Occupational Safety and Health of the German Social Accident Insurance (Institut für Arbeitsschutz der Deutschen Gesetzlichen Unfallversicherung – IFA) presented highlights focussing on “Smart PPE”, “Digitalisation of Work” and “Digital Applications and Solutions” – from the prototype to the mass-produced product. Also addressed were such aspects as the urgently required reorganisation of work processes for the ageing population or the new demands on the world of work from the younger generation.”
 
At the Highest Specialist Level: The A+A Congress
Also enjoying great acclaim was the International Congress for Occupational Safety and Occupational Medicine that is traditionally organised by the Federal Association for Occupational Safety and Health (Bundesarbeitsgemeinschaft für Sicherheit und Gesundheit bei der Arbeit e.V. – Basi). “We had a very exciting A+A congress,” was the verdict of Basi Managing Director Bruno Zwingmann. “For the first time we were able to welcome to the congress new groups of people interested in occupational safety – for instance, representatives of the severely handicapped who also discussed the founding of an umbrella association at the congress.” Over the four days of the trade fair a total of some 5,000 congress delegates streamed into CCD Congress Center Düsseldorf Süd to gather information on the varied range of topics on offers. The 60 focal series dealt with such topics as production operations in the location of Germany with ageing workforces, positive aspects of digitalisation and mental stress with a focus on small businesses and their working conditions. The top events included one focusing on the “Fighting Cancer at the Workplace”. The A+A Congress was accompanied by the conference of the International Labour Organisation (ILO) and the International Social Security Association (ISSA) attended by top ranking figures.

A Burning Issue: Fire Prevention
As the most important sectoral platform worldwide for personal protective equipment and protective workwear A+A once again this year showcased everything revolving around modern firefighters protective clothing as well as the entire spectrum of personal protective equipment for firefighters: be this head, eye, body, hand, foot, ear, breathing or rope protection. Also on display were the preventative measures and concepts that can help to prevent accidents, major disasters and rescue missions and how firefighters are trained in realistic conditions in real fires.
The next A+A will be held from 5 to 8 November 2019.
