• Exceptional achievement of research work on the use of Nuclear Magnetic Resonance (NMR) spectroscopy for understanding PET depolymerization enzymes

Carbios (Euronext Growth Paris: ALCRB), a pioneer in the development of enzymatic solutions dedicated to the end-of-life of plastic and textile polymers, announces the publication of an article entitled “An NMR look at an engineered PET depolymerase” in the scientific journal Biophysical Journal.

The article describes the use of Nuclear Magnetic Resonance (NMR) spectroscopy to study the thermal stability of PET depolymerization enzymes and the mechanism of adsorption of the enzyme on the polymer. This innovative approach, which required months of development, is a world first and opens up new ways of improving these enzymes. This publication confirms Carbios' international lead in the development of the most efficient enzymes for the depolymerization and recycling of plastics.

Prof. Alain Marty, Chief Scientific Officer of Carbios and co-author of the article, explains: “ Nearly 25 researchers are currently working on our unique enzymatic technology. It is based on academic collaborations with the world's leading experts in their fields..”

Dr. Guy Lippens, CNRS Research Director and co-author of the artcle, adds: “Nuclear Magnetic Resonance (NMR) is an extraordinary biophysical technique for visualizing an enzyme directly in solution. Our study is the first to use NMR as a complementary technique to crystallography and molecular modeling to observe a PETase. This gives new perspectives to better understand the functioning of these enzymes and it makes it possible to imagine new ways of improving these enzymes. ”

• The Borvida™ portfolio introduces sustainable base chemicals to Borealis’ range of product offering
• The range will initially be based on non-food waste biomass, and chemically-recycled waste; in the future it will also draw from atmospheric carbon capture
• The traceability of the content will be based on Mass Balance, which is ISCC PLUS certified
• This is the next step in an ambitious sustainability journey, which will see Borealis move away from traditional fossil-based feed

Borealis is strengthening its EverMinds™ circular product offering with Borvida™, a range of sustainable base chemicals.

The Borvida portfolio will offer base chemicals or cracker products (such as ethylene, propylene, butene and phenol) with ISCC Plus-certified sustainable content from Borealis sites in Finland, Sweden and Belgium. The move is part of Borealis’ broader commitment to a Future-Positive Revolution, in which the unrivalled benefits of base chemicals and polymers can be enjoyed at minimal impact to the planet.   

The portfolio will initially comprise Borvida B, from non-food waste biomass, and Borvida C, from chemically-recycled waste. In the future, the range will evolve to include Borvida A, sourced from atmospheric carbon capture. Borvida is complementary and is the building block to Bornewables™, a portfolio of polyolefins based on renewably-sourced second generation feedstocks, and Borcycle™, which offers circular polyolefins produced from mechanically- and chemically-recycled plastic waste.

Borealis produces a wide range of base chemicals for use in numerous industries based on various feedstock, such as naphtha, butane, propane and ethane. Through its olefin units (steam cracker and propane dehydrogenation), it converts these into the building blocks of the chemical industry: ethylene, propylene and C4 hydrocarbons (butylenes, ethyl tertiary-butyl ether (ETBE) and butadiene), and C5-6 hydrocarbons (pygas, phenol) among others.

The basis of the Borvida portfolio is Mass Balance, a Chain of Custody model that enables sustainable content to be tracked, traced, and verified through the entire value chain, offering sustainability-assured products from feedstock to end product. Using this model, circular alternatives can be offered in a cost-effective and environmentally-conscious way, which can be scaled up quickly without compromising on quality or efficiency.

Borvida can be used for a wide range of different polymer and chemical applications, also beyond polyolefins (PO). Non-PO polymers, such as polycarbonates, acrylonitrile butadiene styrene (ABS), super absorbant polymer (SAP) and other chemicals, are utilised for various end applications including coatings, plasticizers, adhesives, automotive, electronics, lubricants, detergents, appliances and sports equipment.

Together with key strategic partners, including Neste and Covestro, Borealis strives to provide a long-term solution in order to allow value-chain partners to meet their sustainability goals. Borvida will enable our customers to increase the sustainability of their products, keeping them ahead of forthcoming legislative changes, and meeting their customers’ demands for climate-conscious products.

Introduced on a smaller scale in early 2020, early renewable base chemicals customers include Covestro. “The use of alternative sustainable raw materials is one important pillar of our strategic ambition to become fully circular”, comments Frank Dörner, Managing Director Covestro Procurement Services GmbH & Co. KG. “The new product line is a good example for joint solutions, another strategic pillar, in order to establish new and reliable supply chains creating benefits for our customers.”

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.

• 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.

• The plan for the reference plant is to be operational in 2025 in France (Longlaville) with a processing capacity of 50.000 tons of PET waste per year and creating 150 direct and indirect new jobs.
• Indorama Ventures, the world’s largest producer of recycled PET for beverage bottles, plans to co-invest in this project3 and will consider expanding Carbios’ unique biological recycling process at other PET sites4 for future developments.
• This strategic project is strongly supported by the French Government and the Grand-Est Region, with significant non-dilutive financing.

Carbios (Euronext Growth Paris: ALCRB), a pioneer in the development of enzymatic solutions dedicated to the end-of-life of plastic and textile polymers and Indorama Ventures (Bloomberg ticker: IVL.TB), one of the world-leading PET manufacturer, jointly announced a collaboration to build a manufacturing plant operating Carbios’ PET bio-recycling technology at Indorama Ventures’ PET production site in France (Longlaville, Meurthe-et-Moselle).

After having successfully started-up its demonstration plant in Clermont-Ferrand, Carbios is moving one step further towards the industrialization and commercialization by partnering with Indorama Ventures. The goal is to build and operate in France the world’s first industrial-scale enzymatic PET bio-recycling plant, with a processing capacity estimated at ca. 50.000 tons of post-consumer PET waste per year, equivalent to 2 billion PET bottles or 2.5 billion PET trays.

The capital investment required for the project is expected to be around €150 million for Carbios core technology, including in particular an additional purification step, which has been integrated into the process. In addition, an estimated €50 million investment will be allocated for the infrastructure preparation of the site. The project is expected to create approximatively 150 direct and indirect full-time jobs. In the coming months, Carbios expects to finalize a strong non-dilutive financial support from French Government and from the Grand-Est Region5, based on the offer received last week by Carbios, from the Minister of Industry, Agnès Pannier-Runacher and the President of Grand-Est Region, Jean Rottner.

This financial support will be conditional on the notification to the European Commission and on contractualization by French authorities. Carbios announced in its half-year results on the 30th September 2021 a cash position of €112 million. Since then, Carbios has also secured a €30 million loan from EIB.

With just 3 months to go before Techtextil Frankfurt, UK company Fibre Extrusion Technology Limited (FET), is looking forward to exhibiting at this trade show once again. Techtextil attracts international blue-chip companies at the cutting edge of technology, seeking innovative solutions to technical challenges, so this event represents an ideal opportunity to demonstrate how FET can help achieve their goals.

FET is an acknowledged leader in laboratory and pilot meltspinning equipment for a vast range of applications, such as precursor materials used in high value technical textiles, sportswear, medical devices and specialised novel fibres from exotic and difficult to process polymers. Where melt spinning solutions are not suitable, FET provides a viable alternative with pilot and small scale production wet spinning systems.

However, FET will also showcase at Techtextil its more recent laboratory scale spunbond system, which enables client development of nonwoven fabrics in a number of formats and polymers. FET already has a number of spunbond systems in the field, including composite systems which utilise both spunbond and meltspun functions.

A major theme to be highlighted on the FET stand is Sustainability. The FET range of laboratory and pilot extrusion lines is ideally suited for both process and end product development of sustainable materials.

FET has successfully processed almost 30 different polymer types in multifilament, monofilament and non-woven formats, collaborating with specialist companies worldwide to promote greater sustainability through innovative manufacturing processes.

Over 400 employees work hard every day to improve the environmental performance of Radici Yarn’s site. Through teamwork and continuous improvement in energy efficiency, Radici Yarn has obtained ISO 50001 Energy Management Systems certification, which attests to the organization’s commitment to contain and progressively reduce energy consumption.

Radici Yarn, one of the companies in the RadiciGroup Advanced Textile Solutions Business Area, is engaged in the production and sale of polyamide 6 polymer, PA6 and PA66 continuous filament and staple yarn, and other synthetic fibres, including products made of recycled or bio-based materials.

All the processes - polymerization and spinning (Villa d'Ogna plant), as well as warping and draw-warping (Ardesio plant) - are run under constant monitoring with the goal of achieving maximum energy efficiency and lower consumption. Both sites are powered by two hydroelectric power plants owned by Geogreen, a RadiciGroup partner and energy supplier. The share of energy consumption from renewable sources and reduced environmental impact (natural gas) sources  is constantly increasing.

The energy issue has always been a priority for Radici Yarn, whose products serve numerous sectors, including automotive, clothing and furnishings.

"Already at the beginning of the 1990s, Radici Yarn started investing in cogeneration, the simultaneous production of electricity and steam,” pointed out Laura Ravasio, energy manager of Radici Yarn SpA. “We have recently started up an advanced trigeneration plant – a highly efficient system that produces not only electricity and steam, but also chilled water for our production processes. One of the first results recorded in 2021 was a 30% reduction in water consumption. Thus, ISO 50001 certification seemed like the next logical step to take in formalizing a long-term approach to energy.”

The ISO 50001 certification, which is voluntary and valid for a period of three years, was added to the ISO 14001 Environmental and ISO 9001 Quality Management system certifications previously achieved by Radici Yarn.

• RadiciGroup and DKB introduce the first “circular” ski suit
• A garment made of yarn obtained from recycled materials and designed with end-of-life recyclability in mind, without compromising style, design and technical performance.
• RadiciGroup Ski Club athletes will be the first ambassadors of this sustainability project

The first truly sustainable ski suit, featuring Italian style and design and a zero-kilometre supply chain, is finally here. Two Bergamo companies of excellence played the leading roles in the conception and realization of this highly innovative fashion-sport garment: RadiciGroup, a world leading producer of chemical intermediates, polyamide polymers, high-performance engineering polymers and advanced textile solutions, and DKB, a company specializing in technical sportswear with the same brand name.

The ski suit, consisting of jacket and trousers, is fashioned with a fabric made of RENYCLE, a RadiciGroup yarn obtained from mechanically recycled polyamide (nylon), which affords notable savings in energy and water consumption, as well as lower CO2 emissions. In addition, the suit’s padding and numerous accessories, such as zippers, Velcro, buttons and thread, are also made of polyamide.

This achievement was made possible by the great teamwork of RadiciGroup and DKB on the research and development of chemically compatible materials that can be used in special applications requiring high technical performance. The end result is an almost mono-material garment that significantly facilitates end-of-life recycling. It can be more easily converted into polymers for use in the manufacture of ski boot components and bindings, in addition to applications in the automotive and furnishing industries, or in any other sector requiring the characteristics of high performance polyamides.

The ski suit by RadiciGroup is thus an all-round application of ecodesign and circular economy principles to fashion and garment making, which justifies the claim “Una sostenibilità all’altezza delle nostre montagne” [Sustainability worthy of our mountains] written in a logo patch on the inside of the jacket.

“I am particularly proud of this achievement, a synthesis of my passion and effort,” said Angelo Radici, president of RadiciGroup. “I’ve always loved mountaineering and skiing, and, together with my collaborators, I work hard at our company day in and day out to find innovative solutions that improve the sustainability of our industry. This ski suit is concrete proof of the fact that textiles and apparel can be made sustainable without compromising on comfort, design, looks or performance. I will never get tired of repeating that collaboration among the firms along the production chain is crucial to manufacturing goods with an ecodesign approach, considering their end-of-life recyclability and, thus, potentially giving them unlimited durability. Upstream producers, like us, gladly share our know-how in materials chemistry and experience in recycling with our downstream partners, so that, together, we can find sustainable and viable solutions in the various sectors where we operate.”

SABIC has announced that the newly formed Hygiene & Healthcare segment of its Petrochemicals business will showcase its extensive portfolio of SABIC PURECARES™ polypropylene (PP) and polyethylene (PE) polymers for high-purity nonwovens and hygiene films at the upcoming INDEX™ Expo in Geneva, Switzerland, from October 19 through 22, 2021. The company will also present enabling solutions developed with partners to address the issue of plastic waste and support the transformation of the industry towards a circular economy with closed-loop initiatives and certified circular polymers under its TRUCIRCLE™ portfolio and services.

During INDEX, SABIC will exhibit a wide range of PP polymers targeted at these needs. Highlights on display will include dedicated PP and PE grades for lightweight nonwoven fabrics using the latest spunbond and meltblown processes, and a new ultra-high melt flow PP product engineered for meltblown fibers in nonwoven fabrics. The nonwoven focus will be complemented by industry proven polyolefins for cast and blown film applications in hygiene webs and laminates, providing desirable back and top sheet properties such as water tightness, breathability and elasticity.

In addition, SABIC will also present ISCC Plus certified fiber and film polymers based on circular and renewable PP and PE polymer technology as part of the company’s TRUCIRCLE portfolio for advancing the transformation of the plastics industry from a linear to a truly circular economy. Examples of this comprehensive initiative include collaborations with various market leaders in the field. Together with Fibertex Personal Care, one of the world’s largest manufacturers of spunbond nonwovens for the hygiene industry, SABIC is creating a range of high-purity nonwovens for the hygiene market using ISCC PLUS certified circular PP polymer derived from post-consumer plastic waste. In another project, Fraunhofer Institute, SABIC and Procter & Gamble (P&G) joined forces to develop and demonstrate the feasibility of an advanced close-loop recycling process for used nonwoven facemasks.

Beaulieu Fibres International is attending INDEX™20 in Geneva and is excited to accelerate its work helping customers to exceed in product performance and sustainability.

For nonwoven converters serving the hygiene segment, a feature at INDEX™20 will be the company’s optimized Meralux specialty fibre, with fit for use performance and sustainability properties. It offers opacity improvements (reduction of TiO2 for the same opacity levels), higher coverage, higher bulkiness, and improved liquid management.

In addition, Meralux fibres deliver substantial sustainability benefits including about 55% savings in raw materials, with equivalent carbon emission savings, thanks to weight reduction in nonwovens for the same coverage, and higher recyclability of PP/PE.

The latest additions to the hygiene fibres portfolio are Meraspring BICO PET fibres. Meraspring enables nonwovens to combine a softness and loftiness that provides a cushioned, even “well-being”, experience for end-users of applications such as diapers and fem-pads. The fibres are available in a range from 1.7-8.9 dtex with hydrophilic, hydrophobic and wellbeing finishes depending on the properties required in the final product.

In the industrial fibres segment, UltraBond thermal bonding fibre will finally be presented with its INDEX™20 Nonwovens Award in the category "sustainable raw material".

In addition, Beaulieu Fibres International’s new range of MONO low count and BICO fibres are setting new performance standards for the fast-growing air and liquid filtration markets.

At INDEX™20, Beaulieu Fibres International also presenets its Pilot Line to test the waters of co-development opportunities without risk. The Pilot Line offers the utmost flexibility to produce samples, without the typical constraints imposed by industrial production lines, replicating any type of staple fibre spinning technology using different types of polymers and additives and different types of cross sections.
