From the Sector

ECHA CHEM is a new solution for publishing information on chemicals. The first release, available now, includes information from all REACH registrations.

ECHA’s current Information on chemicals platform, launched in 2016, grew rapidly and contains today information on over 360 000 chemicals. In 2022, ECHA announced that it would create a new system for publishing chemicals data. ECHA CHEM allows the Agency to better handle the growing diversity and quantity of data, while taking advantage of technological advancements.

ECHA maintains the largest chemicals database in the European Union (EU), combining industry-submitted data with information generated in the EU’s regulatory processes. ECHA CHEM is the new solution to share with the public the growing amount of information hosted by the Agency.

In the first version of ECHA CHEM, the information from all the over 100 000 REACH registrations are included that companies have submitted to ECHA. Later this year, the database will be expanded with the redesigned Classification and Labelling Inventory, followed by the first set of regulatory lists.

Carbios and L’Oréal have won the “Pioneer Awards” in the Industry category, presented by the Solar Impulse Foundation at the first World Alliance Summit. This prize was awarded to Carbios for its enzymatic PET recycling solution, labeled “Efficient Solution” by the Solar Impulse Foundation since 2019, and to L’Oréal for using this technology for the first time in a cosmetics bottle prototype. Carbios’ solution offers brands an alternative to petro-sourced plastic that helps them meet their sustainability commitments. This advancement paves the way for future applications in other sectors such as packaging, food and beverage, and textiles.

Carbios and L’Oréal: a long-term collaboration
Since 2017, Carbios and L’Oréal have been working together with a shared vision of accelerating the transition to a circular economy for plastic. In 2017, both companies created a Consortium to improve the recyclability and circularity of PET packaging.  Nestlé Waters, PepsiCo and Suntory Beverage & Food Europe joined this Consortium in 2019 to scale up Carbios’ innovation. The world’s first enzymatically recycled PET packaging was made in 2021 using Carbios’ biorecycling process. The world’s first PET biorecycling plant is scheduled to be commissioned in 2025. In parallel, Carbios is rolling out its technology internationally through licensing agreements.

The environmental benefits of biorecycling developed by Carbios
Recent life-cycle analyses^[1] show a 57% reduction in CO₂ emissions compared with the production of virgin plastic^[2], and for every tonne of recycled PET produced, 1.3 tonnes of petrol are avoided. Compared with conventional recycling, enzymatic recycling is 4 times more circular (calculated according to the Ellen MacArthur Foundation’s Material Circularity Indicator). Thanks to its highly selective enzyme, optimized for efficient PET degradation, Carbios’ depolymerization process can process all types of PET waste, including colored, multilayer or textile waste that cannot be recycled using current technologies. Furthermore, the two monomers produced (PTA and MEG) make it possible to recreate recycled PET products of identical quality to virgin ones, and suitable for food contact.

The EU's plans to ban PFAS (per- and polyfluoroalkyl substances) chemicals will have an immense impact on companies globally. Perhaps even more than expected, as many manufacturers are unaware that they may have PFAS chemicals in their product line. A new online tool, launched today by NGO ChemSec, will help to solve this problem.

Just a couple of weeks after the big PFAS restriction proposal in the EU was published, ChemSec launches the PFAS Guide, which helps companies investigate the use of persistent chemicals within their businesses. The main feature of the PFAS Guide is the searchable database uncovering different PFAS uses and functions. The online tool also provides guidance on different aspects of the phase-out process from regulation and investigation all the way to testing and supply chain communication.

“We’ve been working to support companies in chemical substitution for a long time, and the last few years we’ve gathered a group of companies working specifically on the PFAS issue. The discussions with them made it clear to us that a main challenge is understanding if and where in your business you may have PFAS”, says Dr. Anna Lennquist, Project Leader for the PFAS Guide.

PFAS are a source of growing concern
It has been estimated that 95 percent of all manufactured goods rely on some form of industrial chemical process. A large share of the chemicals used in these processes have been linked to adverse impacts on human health and the environment. PFAS are a clear example of this problem. PFAS have been manufactured and used in products such as make-up, non-stick pans, water- and greaseproof textiles, food-packaging materials, and firefighting foam since the 1950s and are still used in a wide variety of products around the world today.

But they are also substances of growing concern due to their problematic properties. Per- and polyfluorinated alkyl substances (PFAS) are a group of several thousand man-made chemicals that accumulate in the environment and cause health impacts for generations. They are, for example, linked to cancer, lung disease, diabetes, reproductive abnormalities and learning difficulties. Since PFAS do not degrade, these “forever chemicals” are now so widespread that is safe to say that every single human being on the planet have detectable levels of these toxic chemicals in their blood.

A couple of weeks ago, a big proposal to restrict PFAS in the EU was published. The five EU Member States behind the proposal submitted a broad restriction proposal that clearly shows the need for the industry to put all resources into phasing out all PFAS substances.

• Formula 1 cars will be cheaper in future

Carbon is the stuff Formula 1 cars are made of, at least the bodywork. But until now, carbon has been expensive. It can be produced more cheaply and efficiently if artificial intelligence monitors the production processes. A camera system combined with artificial intelligence automatically detects defects in the production of carbon fibres. This makes expensive manual inspection of the carbon fibres obsolete and the production price of the carbon fibre can be reduced in the long term.

For this idea, the young engineer Deniz Sinan Yesilyurt received the second prize of the "Digitalisation in Mechanical Engineering" Young Talent Award on 6 December.

Carbon fibres are sought after because of their good properties. They are very light - they weigh up to 50 percent less than aluminium. The combination of low weight and good mechanical properties offers many advantages. Especially in times of the energy transition, lightweight materials like carbon are more relevant than ever before. At the same time, carbon fibres are as resistant to external stresses as metals. However, achieving these good properties of carbon fibres is very complex.

Up to 300 individual fibre strands - bundles of individual fibres - have to be monitored simultaneously during production. If carbon fibres tear, it costs time and money to sort out the damaged fibres. This is just one example of various defects that can occur in the fibres during production.

Therefore, Deniz Sinan Yesilyurt attached a camera to the carbon fibre line that takes pictures of various fibre defects during production and collects them in a database. The artificial intelligence in the camera's information technology system evaluates the fibre defects by assigning the images to predefined reference defects. In doing so, it recognises various fibre defects with a classification accuracy of 99 per cent. The process can also be used in other areas that produce chemical fibres.

Deniz Sinan Yesilyurt received the prize from the German Engineering Federation (VDMA) in Frankfurt am Main, Germany. He is a Bachelor's graduate at the Institut für Textiltechnik (ITA) of RWTH Aachen University. The full title of his bachelor's thesis is: "Development of a Kl-supported process monitoring using machine learning to detect fibre damage in the stabilisation process". The VDMA awarded the prize to a total of four theses from different universities. The prize is awarded for outstanding theses and was offered in Germany, Austria and Switzerland.

Albstadt-based Mayer & Cie. has been named a Top 100 award-winner for the third time as one of Germany’s most innovative small and mid-range businesses. The jury made special mention of the circular knitting and braiding machine manufacturer’s innovative processes. At the centre of the family firm’s further digital development is on the aim to boost its customers’ productivity. Last Friday, 25 June, members of the Mayer & Cie. management received the award from the science journalist Ranga Yogeshwar at the SMB summit in Frankfurt am Main.

For some time now, the focus of development work at Mayer & Cie. has been on lean management in assembly processes, on optimisation of aftersales service, including setting up an online shop for spare parts, and on product lifecycle management, or PLM, which stands for a concept of seamless integration of all the information that arises during a product’s lifecycle. A clean data structure is the basis for these measures, it’s called the “digital backbone”. It means that all product data is processed in the same database and all information is available only once and can be downloaded immediately.

In all, 436 companies, including about ten per cent from machinery and plant engineering, competed for the Top 100 seal of innovation this year. Nearly 300 were successful and were congratulated in person by Ranga Yogeshwar at the SMB summit. He noted that the award winners set a role model example. “Innovators are thought leaders; they are always pioneers too,” said Yogeshwar, who mentors the competition. “They put their products to the test and ask themselves what an ecological society and a climate-oriented world will require of them. And they check the opportunities and challenges that increasing digitisation will bring for forms of cooperation, social relationships and, with them, for employee retention.”

For most textiles, finishing processes are not actually the last stage. Products often need an extra touch of expertise to make them perfectly ready for the customer. At this point in the value chain, that usually means manual tasks – but now there are technical solutions and intelligent systems which can handle complex operations better, while adding extra value and assured quality.
Automation brings reliability and efficiency, ultimately saving costs to produce the right quality every time. Swiss companies are specialized in many of these disciplines, with machinery for fabric inspection and presentation, labelling and tracking, folding and packaging. They have the technology to inspire a new vision at the post-production segment of the textile manufacturing processes. Optimization of workflows, with bottleneck management, is an obvious potential benefit. And it delivers measurable returns on investment. The wider picture with automation will prepare companies for the IoT and Industry 4.0.

New business models
The advantages of automation in mills with high-volume production are obvious: consistent quality, increased efficiency, waste reduction in some cases, as well as significant medium-term cost reductions in every case.
That description focuses on the aims of modern mills in low-cost markets. But producers in Europe and USA could reach out for more. For them, automation could be a game-changer, offering unique new opportunities.
Reshoring is a growing trend now. It shows great potential and is definitely driven by sustainability and changes in consumer mindsets. “We believe that the time is right – the machines and solutions certainly are – to push automation also to the very end of the production line, replacing intensive manual work and take the chance for reshoring. The current situation is kind of a transition time which is expected to last for a couple more years in the textile industry,” says Rueedi. He adds that any investments in these prime markets pay off much faster because of higher labour costs.
Innovation transformed through automation can do much more than simply replacing the nimble fingers of humans. It also enables new business models, guaranteeing prosperous future business, alongside greater job security.

Digital workflow and process control
The Swiss company Maag Brothers is a leading supplier of high-end machines for quality assurance in the final make-up processes, specifically fabric inspection, plating/folding, selvedge printing and packaging. Maag reports on a practical example from a mill in India which recognized the potential of automation.
An analysis at the customer’s mill identified the main goals as modernization of the workflow at quality control and packing processes. Maag’s new system covers tasks from fabric inspection to dispatch, and offers transparent and easily adjustable processes with real-time process control. It’s a digital solution, resulting in a slim organization, paperless, and the basis for further optimization towards Industry 4.0 to exploit its full potential. The customer’s own calculation showed a ROI for the installation at less than three years – along with a reduction in manpower and savings in fabric costs for shade samples.

Perfectly labelled, efficient data...
Smooth processes start with a label. Swiss company Norsel is an expert in grey fabric labelling systems, for piece tracking through all textile processes. High-quality label printing and proper sealing on all kind of fabrics ensure readability and sustainability after dyehouse processes such as mercerizing, high temperature dyeing and even hot calendering. No roll mix-up during dyeing, easy sorting of fabric rolls and rapid delivery make processes in the mill much more efficient. Using RFID codes lifts fabric inventory control to the highest level, with all information readily transferred to a database and integrated through any ERP software.
It’s a foolproof way to avoid the risk of human errors from hand-written notes on grey fabrics and article sheets, by opting for reliable, secure and forward-looking solutions.

Sample collections – the silent salesmen
First impressions count, so fabric producers like to present their collection perfectly – and that’s only possible with automated solutions. Swiss producer Polytex continuously refines its solutions, underlining its leading position in sample making equipment. Fully-automatic high-performance sample production lines are designed to satisfy the highest expectations. Fully-automatic lines or robotic machines set the standards for quality and performance. Even the most demanding clients can achieve their goals with impeccable samples, quickly and efficiently made, for flawless collections that are sure to impress.

Automation drives buying
First impressions are also the trigger for quick purchase decisions. The proof is there on every store shelf. Customers of Espritech are also well aware of it. They trust this Swiss producer of automated folding machinery to provide the final touch of class to home textiles and apparel products before they go on display. The folding systems are generally large mechatronic devices, loaded with latest technologies in mechanics, electronics, sensors and pneumatics. “Textile producers are amazed how folding machines solve the tricky task of reliably handling chaotically behaving materials. They see process optimization potential and the impact. We observe a slow but continuous change of mindset installing sophisticated technology even in the last steps of textile finishing,” says Philipp Rueedi, CFO at Espritech.

Some of the newly added substances are used in consumer products such as cosmetics, scented articles, rubber and textiles. Others are used as solvents, flame retardants or to manufacture plastics products. Most have been added to the Candidate List because they are hazardous to human health as they are toxic for reproduction, carcinogenic, respiratory sensitisers or endocrine disruptors.

Companies must follow their legal obligations and ensure the safe use of these chemicals. They also have to notify ECHA under the Waste Framework Directive if their products contain substances of very high concern. This notification is submitted to ECHA’s SCIP database and the information will later be published on the Agency’s website.

Background
The Candidate List includes substances of very high concern that may have serious effects on our health or the environment. These substances may be placed on the Authorisation List in the future, which means that companies would need to apply for permission to continue using them. The Candidate List has now 219 entries – some of these cover groups of chemicals so the overall number of impacted chemicals is higher.
 
Under the REACH Regulation, companies may have legal obligations when their substance is included – either on its own, in mixtures or in articles – in the Candidate List. Any supplier of articles containing a Candidate List substance above a concentration of 0.1 % weight by weight has to give sufficient information to their customers and consumers to allow safe use.
 
Importers and producers of articles containing a Candidate List substance have six months from the date of its inclusion in the list (8 July 2021) to notify ECHA. Suppliers of substances on the Candidate List (supplied either on their own or in mixtures) have to provide their customers with a safety data sheet.
 
As of 5 January 2021, suppliers of articles on the EU market containing Candidate List substances in a concentration above 0.1% weight by weight must notify these articles to ECHA’s SCIP database. This duty comes from the Waste Framework Directive.
 
More information on these obligations and related tools are available here.

• SGL Carbon supplies first plants with DIN EN1591-1 tightness certification to the chemical industry
• First column already delivered to major European customer

In plant operation in the chemical industry, the tightness of flanged joints is becoming increasingly important when dealing with aggressive and corrosive operating media. In accordance with European Union requirements, the German government has defined new requirements in the first administrative regulation to the Federal Immission Control Act (BImSchG), which will apply from January 2021. SGL Carbon is the first manufacturer of PTFE-lined columns to be able to provide the required proof of tightness according to DIN EN 1591-1 and has already delivered the first column with the new certification to a major European customer.

Specifically, the Technical Instructions on Air Quality Control (TA-Luft) of the Federal Immission Control Act (BImSchG) prescribe new, stricter emission values (leakage class L0.01) for keeping the air clean, which must be complied with when operating plants requiring a permit. In order to be able to guarantee the technical tightness of steel/PTFE flanged joints, SGL Carbon, together with a working group of other companies, first determined the EN 13555 sealing characteristic values, which reflect the material-specific PTFE properties as well as the characteristic manufacture and shaping of the linings. With these characteristic values integrated in a database, SGL experts were able to perform realistic DIN EN 1591-1 calculations for flanged joints of a packed column lined with POLYFLURON PTFE and prove the tightness in accordance with TA-Luft. The design, final acceptance and pressure tests in accordance with Directive 2014/68/EU (PED) were successfully certified by a recognized notified body.

"With the rapid implementation of the new  tightness requirements for columns, our solutions offer customers further significant added value, which is currently also being applied to other products. Our sales team and technical service are available to provide customers with comprehensive advice on the new directives and our products," explains Ralph Spuller, Director Product Management in the Process Technology (PT) Business Unit at SGL Carbon.

Sicomin’s latest marine collaboration with Sonntag Fins sees its industry leading GreenPoxy® 33 bio-based epoxy resin used for custom carbon fibre windsurf fins - combining speed, fatigue performance and sustainability for some of the fastest sailors afloat.

Targeted at windsurf slalom sailors, racers and speed sailors, each Sonntag fin is a custom made product, tailored specifically to the user based on a discussion about riding style, physical size and weight, as well as how the rider likes to load the fin whilst sailing.  This attention to detail and bespoke manufacturing places a huge importance on the performance and consistency of the raw materials used, with all new materials having to be validated in production, on the test rig in the lab, and on the water by the team riders.

With this in mind, Sonntag Fins approached Time Out Composite, Sicomin’s German distributor,  looking for a new resin system that could reduce cycle times and improve manufacturing output.  Bio-based systems were discussed, but the first product used by Sonntag was Sicomin’s SR1280 laminating system which delivered immediate results, enabling shorter cure cycles, and exceeding all of the previous mechanical test targets.

In 2020, Sonntag and Time Out Composite revisited the topic of a more sustainable epoxy resin system. It was the perfect time for Sonntag Fins, with their new unique bright green UV resistant outer finish, to go green on the inside too with Sicomin’s GreenPoxy® 33 resin.

Test fins were produced with the new material performing well in production trials. Pure resin samples were also tested and post-cured at 140 ̊C, with the new GreenPoxy® 33 samples showing significantly higher elongation at maximum resistance, meaning the cured epoxy was less brittle and susceptible to damage should a customer’s fin meet a rock. With mechanical properties improved, Sonntag switched production to GreenPoxy® 33 in August 2020.

Sonntag fins are manufactured in CNC machined aluminium moulds using GreenPoxy® 33 and a bespoke lay-up of woven, stitched biaxial and heat-set unidirectional carbon fibre fabrics in four steps:
• The first step in the moulding process is the application of Sonntag’s unique green in-mould coating.
• Next, the individual fabric plies, cut using precisely machined templates, are placed into the mould and then wet-out with the low viscosity epoxy. With the laminate stack complete, the mould is closed and loaded into a heated press for around 2 hours to consolidate and cure the fin.
• After curing, the demoulded fins are tempered in an oven at 140 ̊C, then only a light sanding is required to create the final surface roughness for optimum flow characteristics in the water.
• Finally, the fins are cut to the required length and the base adapter is molded to the epoxy-carbon blade in a specific mould.
With each fin being optimized for its rider, it is critical that each piece produced will bend and twist in exactly the way it has been designed to do so, providing the rider with exactly the feel and feedback they want for their board and fin. Each Sonntag fin is tested on a unique CNC controlled servo and stepper motor driven test bench that Joerg has developed, building a database of test results that not only ensures the products perform as designed but also validating the consistency of the manufacturing process and raw materials.
“We produce high-performance windsurfing fins that need to accommodate significant loads during sailing. Fins need to combine flexibility with extremely high torsion stiffness that places high interlaminar shear forces on the resin, especially in our softer fins.” commented Joerg Sonntag, MD, Sonntag Fins. “A key requirement for us is a resin that maintains its mechanical properties for many years, and this is where the Sicomin systems deliver”

In the AZL Workgroup "High-Performance SMC", a project was developed in cooperation with M-Base, the IKV and the AZL partner network for the efficient and standardized provision of engineering data for SMC. Within the scope of the project, companies can participate in the definition of the required characteristic material data, the guidelines for the production of test specimens and the test specifications.
Sheet Moulding Compounds (SMC) are used in various application areas such as vehicles, electronics, construction and infrastructure.

Driven by the requirements to reduce the production costs of lightweight components, a new generation of SMC components with high mechanical properties is of highest relevance. SMC offers enormous potential to realize structural components with good lightweight characteristics at significantly reduced costs compared to conventional continuous fiber-reinforced components.
In order to further establish SMC in broad industrial applications companies participating within the AZL Workgroup recognized the value of a data bank for data harmonization of SMC to provide the possibility of easily finding the right material with its characteristics for the needed specific requirements.

“The segment of SMC is with 250,000 tons production per year the largest composites market in Europe. I am very pleased that we start now with the project of data harmonization along the complete value chain. The goal is to have a similar data base as already established by Campus® for thermoplastics and thermoplastic composites. Only with a reliable set data we can convince the engineering experts to use SMC in a larger variety of applications,” says Dr. Michael Effing, Chairman of the Board of AVK and Composites Germany.

As of right now a databank for engineered thermoplastic materials (by Campus®) already exists and is offering an immense value.
Under the lead of M-Base, Dr. CEO Erwin Baur who has successfully established the CAMPUS database, the AZL, IKV and companies along the value chain of long fibre reinforced SMC initiated to build a CAMPUS-compatible data structure and material characterization methodology during the High-Performance SMC Workgroup Meetings.
