From the Sector

With the goal of making recycling of lightweight, high-volume fiber and flake recyclate much more economical and, in some cases even possible, Coperion has developed a new version of its ZS-B side feeder. Using the innovative ZS-B MEGAfeed, plastic recyclate with a bulk density under 200 kg/m³, long considered intake-limited and thus not worth recycling, can be reliably fed in large quantities into Coperion’s ZSK twin screw extruder and be concurrently recycled and compounded.

The ZS-B side feeder’s novel design makes it possible to feed very high rates of fiber and flakes, such as PA, PE, PET, and PP. As a result, the ZSK twin screw extruder’s high capacity can be fully exploited when the ZS-B MEGAfeed is used. Very high throughputs in both mechanical and chemical recycling of post-industrial and post-consumer waste are achieved.

Increased Throughput in Numbers
With a ZSK 58 Mc18 twin screw extruder, the throughput increase and thus the potential of the new ZS-B MEGAfeed becomes very clear. When recycling PA fibers with a bulk density of ~40-50 kg/m3, throughputs of 70 kg/h were previously achieved using conventional equipment. When the PA fibers were fed into the ZSK extruder using the ZS-B MEGAfeed, throughputs increased about fourteenfold to 1,000 kg/h. Similar results were achieved recycling carbon fibers with a bulk density of ~50-70 kg/m3; in this case, throughputs increased from 50 kg/h to 2,500 kg/h using the ZS-B MEGAfeed. When recycling PCR (Post-Consumer Recycled) flakes, throughputs increased from 50 kg/h to 700 kg/h, and from 80 kg/h to 1,300 kg/h with multilayer film flakes.

Key to Economical Recycling of A Wide Variety of Plastics
Plastics previously considered not recyclable are becoming a valuable raw material using the new Coperion ZS-B MEGAfeed. For example, PCR flakes or recyclate from carbon fiber-reinforced plastics can now be fed into the ZSK extruder at high feed rates and recycled economically.

In the case of mechanical upcycling, upstream processes necessary for compounding, such as compacting, melting and agglomeration, are completely eliminated using the ZS-B MEGAfeed technology. In this recycling process, flakes and fibers can be fed directly into the ZSK extruder, where they are melted, compounded, devolatilized, and filtered in a single step. In so doing, both investment costs and energy consumption drop. The production process becomes significantly more efficient. Moreover, the thermal product stress is reduced and recyclate quality increases.

Even when recycling PET, the feed rate is no longer a limiting factor. With the ZS-B MEGAfeed, PET flakes and fibers can be fed into the ZSK twin screw extruder in large quantities with no pre-drying or crystallizing, where they can be processed with the highest degree of profitability.

The ZS-B MEGAfeed can also feed large quantities of post-consumer waste, adding appreciable value to the chemical recycling process with the ZSKs. ZSK throughput rates are very high with the ZS-B MEGAfeed. Preheating of the recyclate via mechanical energy input of the twin screws thus becomes even more economical for further processing in the reactor.

Existing Coperion extruders can be retrofitted with ZS-B MEGAfeed technology to greatly expand their spectrum of applications and increase their throughput rates.

• 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.”

Freudenberg Performance Materials (Freudenberg) is endorsing further sustainable products with its ECO-CHECK label introduced last year. These products comply with various environmental criteria. With immediate effect, five more solutions bear the label making the company’s commitment to sustainability visible.

Leather goods
The newly-endorsed ECO-CHECK products include one Evolon® microfilament textile application. This is a reinforcement material for leather goods that is manufactured with no solvent and no binder. It contains up to 80 percent recycled PET and is suitable for a broad range of applications. The material is produced at Freudenberg’s facility in Colmar, France, where the manufacturing process is highly sustainable: it is certified to STeP by OEKO-TEX® and fully complies with the DETOX TO ZERO by OEKO-TEX® criteria.

Healthcare applications
In the field of healthcare, the bio-based M 1714 wound pad with superior absorption for more challenging wounds has now been endorsed with the ECO-CHECK label. The dressing consists of a mix of bio-based fibers derived from natural sources and exhibits a smooth wound contact layer. The product has been evaluated for industrial compostability and conforms to ISO 13432.

Architectural applications
The sustainable TF 400 Eco F mesh fabric for textile architecture from Mehler Texnologies® now also bears the ECO-CHECK label. Its yarn is made of 100% recycled PET bottles and its characteristics are very similar to those of conventional mesh fabrics. In 2021, it was awarded first place by the Architectural Membrane Association (AMA) in the “product” category in recognition of its properties.

Shoes
In the shoe industry, the binder-free strobel insoles have been endorsed as particularly sustainable. They contain a high percentage of recycled green bottle flakes. Moreover, the insoles themselves are fully recyclable.

Filtration applications
The two layered, needle-punched nonwoven filter medium that has just been endorsed with the ECO-CHECK label has impressive sustainability characteristics. Made entirely of polyester, more than half the fibers consist of recycled material.

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.

With an annual report entitled 'Here.We.Go' and a sustainability report 'Shaping sustainable living, together', B.I.G. is also publishing a strong ambition for a sustainable future.

Offering sustainable flooring and material solutions will be the number one priority for the coming years.

The Group's first sustainability report is built around a self-designed sustainability model - "Route 2030" - which is based on achievable commitments, covers the main priorities and reflects B.I.G.'s vision in a sincere way.

Their vision for the B.I.G. change is to actively build a better future by their our carbon footprint to zero and doing business in a transparent, integer way. In this sense, it is the translation of the Group's purpose defined in 2021: shaping sustainable living, together.

Pol Deturck adds “By 2030, together with a broad group of suppliers, stakeholders and partners, we want to be the leader in sustainable flooring and material solutions. Specifically, our future value proposition is based on products and services that are environmentally & climate friendly, circular and offered by talented, innovative people with an emphasis on integrity and respect for values. This results more in a recurring value proposition for the future.”

Clear growth ambitions
As a 100% family-owned international Group with a clear long-term vision, B.I.G. stayed true to their plans and kept on investing in all areas of their business.
“The ambition for 2021 was to invest over 100 mio euro. But we were held back by external, unforeseen factors: from delays on quotes and execution to the lack of availability and resources due to the pandemic. If all goes as planned, we’ll make up for it in 2022 with an investment budget well over 100 million euro. The main areas of interest will be sustainability, innovation and Industry 4.0.” says Pieter-Jan Sonck, CFO of B.I.G.

Adding to the gradual top-line growth of recent years, the Group can look back on an unprecedented financial boom. The driving forces: favorable market conditions, a revitalized growth strategy and a team of nearly 5.000 first-class employees.

B.I.G. reported a turnover of EUR 2,5 billion, an increase of 45 % compared to 2020. The Group ebitda amounted to EUR 451 million, an increase of 120 % compared to 2020 and a net result of EUR 274 million, a growth of 215% compared to 2020.

Fruitful year for all Business Units
It was a fruitful year for all 3 business units, but the Group's business unit Polymers stood out. Exceptionally strong demand in Europe and North America, combined with raw material shortages and unplanned shutdowns of competitors, pushed prices and margins up to highs. The Polymers facilities ran at full capacity to meet the customers’ needs and hit all-time profit records during several months.

The Group's business unit Flooring Solutions also fared well. Most divisions and regions outperformed amid surging energy prices, disrupted supply chains, cost volatility in transport and raw materials, and other challenges. Their sustained focus on innovation, design and product differentiation led to an improved operating result at the end of 2021.

The achievements by Engineered Solutions echo those of the other two business units, from volume increases to budget increases. B.I.G. took big leaps forward in all its key markets, including the automotive sector, geotextiles and filtration.

Indorama Ventures, VALORPLAST, Klöckner Pentaplast (kp) and CITEO collaboration delivers a commercial recycling solution for monolayer PET trays

Thai-based Indorama Ventures Public Company Limited (IVL) with its facility Wellman France Recycling in Verdun, has been working on the PET trays recycling for 6 years and through an ongoing project with VALORPLAST and supported by CITEO.

The project has the objective to develop and validate recycling for monolayer and multilayer PET trays. VALORPLAST has collected significant quantities of post-consumer PET trays and several industrial runs have been conducted by Wellman. The produced flakes are being tested by several actors to develop high quality applications. Those tests have led by IVL to develop a commercially feasible recycling solution for monolayer PET trays with the collaboration of Klöckner Pentaplast.
The new technology is processing monolayer PET trays used for food packaging (meat, produce and cheese) into a high-quality product, suitable for new tray production.

This new recycling innovation will see over 50 million post-consumer PET trays diverted away from landfill or incineration.

Testing has now moved into commercial production. 500 tonnes of PET trays are now being processed monthly and transformed into a high-quality tray flake, which can be used to produce new trays. The purity of the flakes is comparable with high-quality bottle flake. A further scale up is foreseen, and the company plans to process 10KT of tray flake in 2022.

Eurotay showcased at Denim Première Visionits vision and products through the AW 23/24 collection inspired by two themes: Nostalgia and #Still Possible.

Nostalgia stands for heritage and advancement, taking inspiration from classic favorites while enhancing new and existing styles. Setting the tone of the line are vintage-looking washes, echoing the 80s and 90s light acid washes as well as used look with bumped edges or fringed hems. Stretch, comfort stretch with very little elastane and even rigid denim feature in this collection providing catering to any need or preference.

The #Still Possible collection is based on the premise that the textile industry is one of the most polluting ones on the planet, thus it aims to shine a light on how a denim garment can still be made whilst reducing the number of resources employed and by being more conscious about the materials chosen. By using EIM and LCA, garment durability, traceability, recyclability as well as material health are guaranteed, for a collection that looks to a brighter and greener future.

Eurotay has been committed from day one to using less water, less energy, less chemicals to reduce its environmental footprint and its carbon emission and meet the goals of EU Green Deal targets. The company is geared towards building a more and more responsible industry by working hard to reach a set of sustainable goals by 2025. Additionally, the company is working on developing Life Cycle Assessment (LCA) and EPD (Environmental Product Declaration) measuring the global warming, water consumption, land occupation, eutrophication and abiotic depletion performances.

• Sustainable infrastructure solutions, road safety and health protection

At this year’s Techtextil, Oerlikon Polymer Processing Solutions will be presenting the trade audience with new applications, special processes and sustainable solutions focusing on the production of industrial textiles. Among other things, the company will be showcasing new technology for charging nonwovens that sets new standards with regards to quality and efficiency. Between June 21 and 24, the discussions will be concentrating on airbags, seat belts, tire cord, geotextiles, filter nonwovens and their diverse applications.

More polyester for airbags
Airbags have become an integral part of our everyday automotive lives. The yarns used in them are made predominantly from polyamide. As a result of increasingly diverse airbag applications and also the increasing size of the systems used, polyester is today used as well, depending on the application requirements and cost-benefit considerations. Against this background, the Oerlikon Barmag technologies make an invaluable contribution. In addition to high productivity and low energy consumption, they particularly excel in terms of their stable production processes. Furthermore, they comply with every high quality standard for airbags, which – as in the case of virtually all other textile products used in vehicle construction – must provide the highest level of safety for vehicle occupants. And all this without any loss of function in any climate and anywhere in the world for the lifetime of the vehicle.

Buckle up!
Seat belts play a decisive role in protecting vehicle occupants. They have to withstand tensile forces in excess of three tons and simultaneously stretch in a controlled manner in emergencies in order to reduce the load in the event of impact. A seat belt comprises approximately 300 filament yarns, whose individual, high-tenacity yarn threads are spun from around 100 individual filaments.

Invisible, but essential – road reinforcement using geotextiles
But it not just inside vehicles, but also under them, that industrial yarns reveal their strengths. Low stretch, ultra-high tenacity, high rigidity – industrial yarns offer outstanding properties for the demanding tasks carried out by geotextiles; for instance, as geogrids in the base course system under asphalt. Normally, geotextiles have extremely high yarn titers of up to 24,000 denier. Oerlikon Barmag system concepts simultaneously manufacture three filament yarns of 6,000 denier each. Due to the high spinning titers, fewer yarns can be plied together to the required geo-yarn titer in a more cost- and energy-efficient manner.

hycuTEC – technological quantum leap for filter media
In the case of its hycuTEC hydro-charging solution, Oerlikon Neumag offers a new technology for charging nonwovens that increases filter efficiency to more than 99.99%. For meltblown producers, this means material savings of 30% with significantly superior filter performance. For end users, the consequence is noticeably improved comfort resulting from significantly reduced breathing resistance. With its considerably lower water and energy consumption, this new development is also a future-proof, sustainable technology.

New high-tech Staple Fiber Technology Center
Extending to around 2,100 m2, Oerlikon Neumag in Neumünster is home to one of the world’s largest staple fiber technology centers. As of now, these state-of-the-art staple fiber technologies are also available for customer-specific trials.

The focus during the planning and the design of the Technology Center was on optimizing components and processes. Here, special attention was paid to ensuring the process and production parameters in the Technology Center system could be simply and reliably transferred to production systems. Here, the fiber tape processing line is modular in design. All components can be combined with each other as required. And comprehensive set-up options supply detailed findings for the respective process for various fiber products.

The Technology Center is also equipped with two spinning positions for mono- and bi-component processes. The same round spin packs are used for both processes, characterized by excellent fiber quality and properties and meanwhile very successfully deployed in all Oerlikon Neumag production systems. Furthermore, the spinning plant is complemented by automation solutions such as spin pack scraper robots, for example.

• with a ready-to-use swatch book dedicated to its DEEP DIVE sustainable dyeing system for dark, popular color basics

Archroma, a global leader in specialty chemicals towards sustainable solutions, launches its first ever ready-to-use swatch book, dedicated to creating sustainable black and dark color basics for faster time to market, to support its popular DEEP DIVE 2.0 system.

In 2018, Archroma launched its system solutions, a holistic approach aimed at addressing the growing expectations of the public in terms of keeping consumers, and the environment, safe.
Under the umbrella of "The Archroma Way to a Sustainable World: Safe, efficient, enhanced, it's our nature", the Archroma systems are designed to create innovation and performance, whilst reducing the impacts on water, energy and other natural resources. The savings generated by these 70+ system solutions are demonstrated by Archroma's proprietary ONE WAY Impact Calculator, a ground-breaking tool launched in 2012 and continuously upgraded to simulate and optimize the footprint of textile application processes.

One of these systems, DEEP DIVE 2.0, has attracted a lot of interest not just from textile manufacturers but also from major brands and retailers worldwide. This popular system combines Drimaren® Ultimate HD, high-performance reactive dyes, with Blue Magic, an all-in-one pretreatment, Optifix® RUB New liq and Siligen® SIH-S New liq, a finishing treatment improved rub fastness and elegant hand feel, and an effective hydrolyzed dye remover, Cyclanon® XC-W New liq. The result is a shorter dyeing process combining right-first-time productivity, an improved fabric quality for longer lasting end-articles, as well as dramatically reduced water and energy utilization for brands committed to drive more sustainable production. Savings can reach up to 31% water and 34% energy.

The system is ideally suited for medium and dark cottons that have high performing fastness to light, multiple home laundering, saliva – in other words: apparel used for fashion, sports and baby’s wear.
At the same time, interested manufacturers and brands were facing the constant challenge of the fashion industry: time to market.

Often design is separated from execution in the factory and as such often designers initially select color that cannot be met in reality on different fibers or production routes in terms of color flare, metamerism, brightness, depth and now sustainable metrics – leading to lengthy delays and compromises in function, performance and/or color.
Archroma decided to create a dedicated tool aimed at addressing these issues. The company developed a new, unique book with color swatches made with the system that is ready to implement immediately into production thanks to engineered color standards and specifications.

This new tool offers a path to bridge the gap between “art and science” by providing at inspiration phase fully executable deep colors for cotton with controlled color metamerism and at the same time demonstrate water, energy and chemical savings, enhanced color fastness using safe chemistry for the end consumer. As a wardrobe staple, medium to dark shades are very popular with consumers. As a result, most brands and retailers often have and sell up to 60% of medium to dark shades in their seasonal palettes. It’s also the dark shades that use the most water and energy in production, so prioritizing these colors would have the largest ecological positive impact. The 48 colors swatched in the DEEP DIVE 2.0 book have been selected based on market popularity to allow brands and manufacturers to match that very stable market demand. Customers may use these colors as presented, or as inspiration whereby Archroma can create and match new custom colors using the DEEP DIVE 2.0 system.

Christophe Maestripieri, Global Head of the Archroma Brand Studio, the company’s department dedicated to support brands’ projects and innovations, explains: “We wanted to make sure our partners have all the tools they need to convert to more sustainable colors. We had the ideal dyeing system to do that, DEEP DIVE 2.0, with its high performance and reduced impacts on resources. Now, with the new DEEP DIVE 2.0 swatch book, we also offer to brands and manufacturers a way to select sustainable color options that meet the market demand for high quality medium to dark shades which can be implemented into production right away.”
