From the Sector

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.

Stahl, a proponent of responsible chemistry, is submitting a greenhouse gas (GHG) emissions reduction target that is aligned with the most recent guidance provided by the Science Based Targets initiative (SBTi). The new target marks a key milestone on the company’s journey toward carbon neutrality.

Stahl’s SBTi submission includes a specific commitment regarding the company’s Scope 3 upstream emissions, which Stahl aims to reduce by at least 25% over the next 10 years, compared with the base year (2021). This reduction would primarily be achieved by Stahl replacing its fossil-based raw materials with lower-carbon alternatives. The target is a major step towards the objective of limiting global warming temperature increase to 1.5°C above pre-industrial levels by 2050, as agreed at the 2015 Paris Climate Accords.
 
Stahl’s extended commitment builds on the company’s existing targets to reduce its emission for Scopes 1 and 2, which were set shortly after the Paris Agreement in 2015. Stahl has since reduced its Scope 1 and 2 (direct) GHG emissions by more than 30%, thanks to operational efficiency gains and by decarbonizing its energy supply.

Scope 3 GHG emissions cover all the additional indirect emissions that can occur in the value chain, including those associated with purchased raw materials, packaging, business travel, and transportation. Stahl’s Scope 3 emissions currently represent over 90% of its carbon footprint.

On June 13, EREMA Group and Borealis invited representatives of the international plastics and recycling trade press to Upper Austria for a sneak preview of the technological developments and lighthouse projects that the companies will present at K 2022, the plastics industry's international meeting place. The venue for the pre-K event was EREMA Group headquarters in Ansfelden.

EREMA Group K 2022 preview
In Düsseldorf, the subsidiaries of the EREMA Group - which are EREMA, PURE LOOP, UMAC, 3S, KEYCYCLE and PLASMAC - will present their technological innovations, services and support together at a Group trade fair stand for the first time. Seven new recycling systems and components will be presented that enable large-scale plants with a production capacity of up to 6 t/h while setting a milestone in recyclate quality and process stability. This is made possible by technological innovations in the plasticizing unit that have been specially developed for high throughputs with low specific energy consumption, the new EREMA 406 laser filter with a 50 percent larger screening area, and new digital assistance systems that will be launched at K 2022 and made available on the BluPort® customer platform. These include, for example, the PredictOn app, which helps to anticipate and eliminate imminent malfunctions based on continuous measurement and evaluation of machine data.

New series of machines for new target groups
For customers looking for rapidly available recycling systems for simple applications, EREMA Group subsidiary UMAC has an innovation in store for K 2022. The company, which has so far specialised in refurbishing and trading in previously owned equipment, is expanding its business area and in Düsseldorf will launch READYMAC, a standardised, prefabricated recycling solution that can be produced from stock, based on proven EREMA TVE technology.

Finally, in the inhouse recycling segment, PURE LOOP and PLASMAC will round off the wide range of machines offered by the group of companies with their product portfolio.

Live recycling and lighthouse projects at the Circonomic Center
In the outdoor area of the K show, EREMA will bring plastics recycling to life with live demonstrations in conjunction with cooperation partners. Different waste streams are processed for this purpose. The wide variety of high-quality applications for recyclate will be showcased in the "products made of recyclate" exhibition, ranging from technical components to consumer goods and food packaging.

Borealis – accelerating the transition towards a more circular future
Borealis is committed to using their expertise and global reach to advance the circular economy of plastics. At the joint Pre-K 2022 kick-off on June 13, Borealis provided a preview of their integrated way of circular thinking and featured topics and activities at the K Fair 2022 in October. The preview covered new technologies and innovations including new packaging and infrastructure applications of the Bornewables™ portfolio of circular polyolefin products, manufactured with renewable feedstocks. New applications for Design for Recyclability, Re-Use, chemical recycling and advanced mechanical recycling were also on display.

International technology group ANDRITZ has established a new inline Wetlace™ CP pilot line with an original design at its center of competence in Montbonnot, France. The line combines both spunlace and wetlaid technologies.

From now on, partners will be able to conduct trials and test all options available for wipes production – from carded staple fibers to pulp and various combinations thereof. The combination of both spunlace and wetlaid technologies offers to move forward to more sustainable options while maintaining a high level of product quality, in particular by achieving high CD strength and good linting properties.

Over the past few decades, ANDRITZ has continued to innovate with various nonwoven processes, like spunlace, WetlaceTM and Wetlace™ CP, with the aim of optimizing the use of raw materials and focusing on sustainability by reducing the synthetic fiber content. Facing the growing demand for bio-wipes in parallel with enforcement of the EU’s single-use plastics directive last year, ANDRITZ has decided to support its customers making their investment decisions.

The Montbonnot pilot line has been rebuilt to integrate the new headbox inside the spunlace line. Pulp can be fed in directly and entangled with carded staple fibers to produce unique nonwoven fabrics designed for end uses as bio-wipes.

• New yarns for the contract furnishing world, for industrial sewing threads and the challenge of biodegradable polyester

At the product level, big impulse has been given to the range of industrial sewing threads for various uses, with new references both in the polyester + polyester compositions as well as in cotton + polyester. The industrial threads, marketed as raw material, allow the company to consolidate its position on some strategic markets, such as in Germany.

As a result of the partnership with Trevira® for the spinning of the flame-retardant Trevira^®CS fibre, Filidea Technical Yarns reinforces its offer of non-dyed performant yarns aimed at the world of contract furnishings. The sector of hospitality, of furnishings for public and work spaces, fairs and areas for social-cultural gatherings will find a comprehensive answer to its demands in the Trevira^®CS-based yarns: with regard to fireproof standards, versatility, resistance to wear and tear, excellent colour rendering, and last but not least, the component of fibre sustainability, an essential value for the design of spaces for collective use.

Continuing in the development of sustainable production across the sector, the company has undertaken two important initiatives with other actors in the textile supply chain. Filidea participates in Trick, the European blockchain project – part of the European Horizon 2020 programme – involving 29 partners from six different nations to reinforce the circular economy thanks to the development of a digital platform which is complete, traceable and available to operators in the textile sector.

MagnoLab, the network of enterprises in the textile supply chain, and of which Filidea is one of the founding members, gives the impulse to constant R&D activities. MagnoLab was established in 2022 in order to develop tangible solutions for the sector, to create values and to collaborate with regard to current and future demands.

MagnoLab brings together textile companies which are active at various stages of and with complementary roles in the supply chain, and which work in synergy and share objectives, resourcefulness and long-sightedness, with the aim of developing innovation in a structured way. MagnoLab is also open to welcome new partners.

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.

The ReHubs initiative brings together key European and world players to solve the European textile waste problem by transforming “waste” into a resource, and to boost textile circular business model at large scale.

This collaboration is set to turn the societal textile waste issue into a business opportunity and to fulfil the EU ambitions of the Green Deal, of the mandatory texile waste collection by end 2024 and the transition into Circular Economy.

In 2020 EURATEX launched the ReHubs initiative to promote collaboration across the extended textile value chain and considering all perspectives on chemicals, fibers making, textiles making, garments production, retail and distribution, textiles waste collection, sorting and recycling.

In June 2022 ReHubs completes a Techno Economic master Study (TES) which researches critical information on the feedstock (textile waste) data, on technology, organizational and financial needs to recycle 2.5 million tons of textile waste by 2030 and to effectively launch the ReHubs.

EURATEX’s ReHubs initiative plans to pursue fiber-to-fiber recycling for 2.5 million tons of textile waste by 2030
According ReHubs Techno Economic Master Study (TES), the textile recycling industry could generate in Europe around 15,000 direct new jobs by 2030, and increase need for nearshoring and reshoring of textile manufacturing.

The textile recycling industry in Europe could reach economic, social and environmental benefits for €3.5 billion to €4.5 billion by 2030
“Transform Waste into Feedstock” announced as first project supported by the ReHubs, and aiming at building up a first 50,000 tons capacity facility by 2024.

Europe has a 7-7.5 million tons textile waste problem, of which only 30-35% is collected today.  

Based on the ambitious European Waste law, all EU Member States must separately collect the textile waste in 2 years and half. While some countries are designing schemes to face the waste collection challenge, currently no large-scale plan exist to process the waste.

The largest source of textile waste (85%) comes from private households and approximately 99% of the textile waste was made using virgin fibers.

Euratex  assesses that to reach a fiber-to-fiber recycling rate of around 18 to 26 percent by 2030, a capital expenditure investment in the range of 6 billion € to 7 billion € will be needed, particularly to scale up sufficient sorting and processing infrastructure. The economic, social, and environmental value which could be realized, potentially total an annual impact of €3.5-4.5 billion by 2030.

Once matured and scaled, the textile recycling industry could become a profitable industry with a total market size of 6-8 billion € and around 15,000 direct new jobs by 2030.

Next steps of the ReHubs initiative

• A European textile recycling roadmap proposing Objectives and Key Results to recycle fiber-to-fiber 2.5 million of textile waste by 2030
• A leading collaboration hub with large players and SMEs from across an extended European textile recycling value chain
• A first concrete portfolio of 4 launching projects:
  - Transform textile waste into feedstock
  - Increase the adoption of mechanically recycled fibers in the value chain
  - Expand capacity by solving technical challenges for thermo-mechanical textiles recycling
  - Create capsule collection with post-consumer recycled products

The 1^st project addresses current sorting technologies which have limits to identify materials with sufficient accuracy for the subsequent circular recycling processes. The “Transform Waste into Feedstock” project will focus on further developing and scaling such sorting technologies. The project group led by Texaid AG aims on building up a first 50,000 tons facility by the end 2024.

On the occasion of the Techtextil fair in Frankfurt, the Chairman of VDMA’s Walter Reiners-Stiftung Foundation, Peter D. Dornier, has awarded prizes to seven successful young engineers. For the first time, the Foundation awarded two Sustainability Awards. They are awarded to academic works in which, for example, solutions for resource-saving products and technologies are developed.

• 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.”

The ongoing revision process to the GOTS Standard document and supporting Manual for Implementation garnered a robust response during its first public comment period, which ended on June 13 and elicited over 300 inputs. Of that, about 60 percent of comments were related to technical criteria such as ecology, chemical inputs, and material quality; and around 30 percent concerned GOTS social criteria. The Standard sets forth the requirements for organic textiles throughout the entire processing chain. GOTS’s commitment to making every version stronger ensures that the Standard continues to be a dynamic and evolving document and remain at the forefront as the most recognized and respected global standard for textiles.

The first draft of the revised standard, GOTS version 7.0, was made available for an initial 60-day comment period. Stakeholders, associations, organisations, companies and individuals were encouraged to contribute to the revision of the Standard during this timeframe. The Standard is updated every three years, ensuring that GOTS keeps up with advances in the industry and developments in the science and technology of textile processing.

Beginning in 2022, the GOTS revision process is following a newly developed and more inclusive Standard Setting Procedure, which includes oversight of the process by a Standard Revision Committee (SRC). The SRC consists of experts from different stakeholder groups, including scientists, textile industry professionals, sustainability, sourcing and human rights specialists and others. Members work together throughout the entire revision process to establish terms of reference and make decisions on any changes.

The comments received are being compiled and will be available for viewing on the GOTS website shortly. For the next stage of the revision process, the SRC will deliberate all comments, and a second draft of the revision will be released for a second and final 30-day period of public input in September 2022, which will be announced on the GOTS website and social media. The final version of the revised standard, GOTS version 7.0 will be released in March 2023, and will come into effect one year later.
