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.

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.

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.”

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.

• Finnish fashion and textile technology company Infinited Fiber Company plans to build its first commercial-scale Infinna™ fiber factory at Stora Enso’s Veitsiluoto industrial site in the city of Kemi in Finland’s northernmost region of Lapland. Infinited Fiber Company plans to convert a building currently housing a discontinued paper production line.
• The size of Infinited Fiber Company’s planned investment is around EUR 400 million.
• The planned factory is expected to create around 270 jobs at the Veitsiluoto industrial site.
• The factory is expected to operate at full capacity in 2025.

Fashion and textile technology company Infinited Fiber Company plans to build a commercial-scale factory to produce regenerated textile fiber for the world’s leading apparel companies at the site of renewable materials company Stora Enso’s closed Veitsiluoto paper mill in Kemi, a Finnish city on the northern shore of the Baltic Sea. The size of the investment is estimated at EUR 400 million, and it is expected to create around 270 jobs in the area. The annual fiber production capacity of the planned factory is expected to be 30,000 metric tons, which is equivalent to the fiber needed for about 100 million T-shirts.  

Infinited Fiber Company’s technology enables cotton-rich textile waste to be transformed into a versatile, high-quality regenerated textile fiber called Infinna™, which looks and feels like cotton. Major international fashion and apparel companies – including Zara’s parent company Inditex, PVH Europe, which is known for the Tommy Hilfiger brand, Patagonia, PANGAIA, H&M Group and BESTSELLER – have already committed to Infinna™ purchases through multi-year agreements as they look for materials that enable the industry to shift towards circularity. Infinited Fiber Company expects to export most of the output of its planned factory. This makes Kemi an ideal location as the city’s port serves as an efficient link to the rest of the world.

Infinited Fiber Company will convert a building housing a discontinued paper production line into an Infinna™ fiber factory. Both the factory engineering and project implementation as well as the related financing negotiations were commenced at the beginning of the year and are progressing well. Infinited Fiber Company has also agreed on the provision of energy and water related services with utility infrastructure company Nevel.

Once up and running, the factory is expected to provide direct employment for around 220 people, and for a further 50 through on-site support functions such as services, maintenance, and logistics. The additional indirect employment impact is estimated to be around 800 jobs. The construction and installation phase is expected to create jobs equaling around 120 person-years. The factory is anticipated to operate at full capacity in 2025.

At Heimtextil Frankfurt 2022, Devan, will launch novel technologies to the Home Textiles market. The first innovation is a range of bio-based and biodegradable microcapsules. With increased sustainability and circularity requirements in Europe and beyond, Devan is pushing the limits further of its encapsulation methods, also in terms of wash durability. The capsules are biodegradable and hence no harm for risk of microplastics. The new R-Vital NTL range includes evergreen Aloe Vera, waste-material based avocado seed oil with very high hydration abilities! and Vitamine E.

Devan, as part of the Pulcra Chemicals Group, co-launches the new Pulcra TEC-SU, a new biobased C0 DWR. This hydrophobic agent has a bio-content above 60% and contains no APEO or formaldehyde. It keeps performing very good after multiple washings.

The Devan bio-based thermoregulation range, like Tones of Cool Bio which is already several years on the market, is having a positive effect on carbon footprint. Devan is now expanding its cooling range with a specific foam-solution. In the Home Textile industry new (bio)foam types are introduced the last 1,5 years to comply with the EU GreenDeal and circularity / recycling requirements. A good enough reason for Devan to develop a foam-specific cooling system. After all, research shows that our bedroom interiors get warmer every year, partly due to better insulation but also due to global warming. On top of that Devan thermoregulation solutions can save Energy and Water during application: low curing solutions are available next to cooling products to that can be applied, using less water.

International technology group ANDRITZ will be presenting its innovative nonwovens production solutions for wipe applications at the international World of Wipes (WOW) 2022 conference in Chicago, USA, from June 27 to 29, 2022.

ANDRITZ’s “We Care” sustainability program combines all ESG (Environment, Social, Governance) initiatives, goals, and achievements under one roof. For many years now, ANDRITZ has been offering various nonwoven processes to produce best and cost-effective wipes, for example spunlace, Wetlace and Wetlace CP. ANDRITZ also accompanies nonwovens producers in the move towards sustainability with the aim of reducing or eliminating plastic components while maintaining the high quality of the desired product properties. This applies to all types of sustainable wipes, such as flushable, biodegradable, bio-sourced, carded-pulp or standard carded wipes. Indeed, hydroentanglement has the advantage of being able to bond any kind of fibers without the use of chemical binders or thermal fusion.

The latest development in this field is the ANDRITZ neXline wetlace CP line, which integrates the card-pulp (CP) process. This is a fully engineered production line combining the benefits of drylaid and wetlaid technologies to produce a new generation of biodegradable wipes.

ANDRITZ has become a member of the board of the Responsible Flushing Alliance (RFA) in the USA. The RFA is an independent, non-profit trade association committed to educating consumers in responsible and smart flushing habits to help reduce damage to the nation's sewage systems. ANDRITZ is deeply involved in this topic with its technologies for 100% dispersible and biodegradable wet wipes and is highly committed to being part of the RFA.

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.
