• Aims to tackle the immense textile waste generated in urban environments, on the back of import bans of waste materials
• Addresses the shortcomings of current textile recycling technologies, which are unsuitable for urban settings due to the use of heavy chemicals
• Technologies developed by the newly-formed RGE-NTU Sustainable Textile Research Centre will be test-bedded in RGE’s pilot urban-fit textile recycling plant, projected for completion as early as 2024

Royal Golden Eagle (“RGE”), a global group of resource-based manufacturing companies, which includes a world-leading viscose fibre producers Sateri and Asia Pacific Rayon (APR), is developing urban-fit, closed-loop textile-to-textile recycling solutions, through the newly-formed RGE-NTU Sustainable Textile Research Centre (RGE-NTU SusTex). This is a five-year research collaboration between RGE and Nanyang Technological University, Singapore (“NTU”), to accelerate innovation in textile recycling that can be deployed in urban settings. The research centre will develop new technologies to recycle textile waste into fibre and create new, next-generation eco-friendly and sustainable textiles.

This move comes on the back of the tightening of waste import bans in countries such as China, India and Indonesia, which are among the world’s largest waste processors. The stricter import bans have left cities in need of viable local textile recycling solutions to tackle the immense textile waste generated.

RGE Executive Director, Mr Perry Lim, said, “Current textile recycling technologies, which rely primarily on a bleaching and separation process using heavy chemicals, cannot be implemented due to environmental laws. At the same time, there is an urgent need to keep textiles out of the brimming landfills.” He added, “As the world’s largest viscose producer, we aim to catalyse closed-loop, textile-to-textile recycling by developing optimal urban-fit solutions that can bring the world closer to a circular textile economy.”

Globally, an estimated 90 million tonnes of textile waste is generated and disposed of every year, with less than 1% being upcycled into new clothing or other textile materials. By 2030, the amount of global textile waste, which currently accounts for almost 10% of municipal solid waste, is expected to reach more than 134 million tonnes. The textile industry is also responsible for 10% of global greenhouse gas emissions – more than international flights and maritime shipping combined.

At present, most of the available textile recycling technologies are open-loop, where textile waste is typically downcycled to lower-quality products (insulating materials, cleaning cloths, etc.) or be used in waste-to-heat recycling.

“Closed-loop textile-to-textile recycling processes, particularly chemical recycling, are still under development. Scaling up the technologies to industrial scale remains a challenge. A key bottleneck is that refabricating textile waste into fibre needs purity standards for feedstock. However, most of the clothes that we wear are made of a mixture of different synthetic and natural fibres, which makes separating the complex blends of materials challenging for effective recycling.

“Our aim is to address this industry pain point by developing viable solutions that use less energy, fewer chemicals and produces harmless and less effluents, and then potentially scale up across our global operations,” Mr Lim said.

To tackle the key challenges in closed-loop textile recycling, RGE-NTU SusTex is looking into four key research areas, namely cleaner and more energy efficient methods of recycling into new raw materials, automated sorting of textile waste, eco-friendly dye removal, and development of a new class of sustainable textiles that is durable for wear and, at the same time, lends itself to easier recycling.

Technologies developed by RGE-NTU SusTex will be test bedded at RGE’s pilot urban-fit textile recycling plant in Singapore, which is projected for completion as early as 2024. If successful, RGE has plans to replicate the plant in other urban cities within its footprint.

• An innovative European project to process and recycle plastic textile waste
• A partnership to reach the objectives set by the European Union in reducing CO2 emissions by 2030
• A unique consortium rallying 16 public and private European organizations working together for more circular economy

Carbios joined WhiteCycle, a project coordinated by Michelin, which was launched in July 2022. Its main goal is to develop a circular solution to convert complex^[1] waste containing textile made of plastic into products with high added value. Co-funded by Horizon Europe, the European Union’s research and innovation program, this unprecedented public/private European partnership includes 16 organizations and will run for four years.
 
WhiteCycle envisions that by 2030 the uptake and deployment of its circular solution will lead to the annual recycling of more than 2 million tons of the third most widely used plastic in the world, PET^[2]. This project should prevent landfilling or incineration of more than 1.8 million tons of that plastic each year. Also, it should enable reduction of CO2 emissions by around 2 million tons.
 
Complex waste containing textile (PET) from end-of-life tyres, hoses and multilayer clothes are currently difficult to recycle, but could soon become recyclable thanks to the project outcomes. Raw material from PET plastic waste could go back into creation of high-performance products, through a circular and viable value chain.
 
Public and private European organizations are combining their scientific and industrial expertises:

• industrial partners (Michelin, Mandals, KORDSA);
• cross-sector partnership (Inditex)
• waste management companies (Synergies TLC, ESTATO);
• intelligent monitoring systems for sorting (IRIS);
• biological recycling SME (Carbios);
• product life cycle analysis company (IPOINT);
• university, expert in FAIR data management (HVL);
• universities, research and technology organizations (PPRIME – Université de Poitiers/CNRS, DITF, IFTH, ERASME);
• industry cluster (Axelera);
• project management consulting company (Dynergie).

 
The consortium will develop new processes required throughout the industrial value chain:

• Innovative sorting technologies, to enable significant increase of the PET plastic content of complex waste streams in order to better process them;
• A pre-treatment for recuperated PET plastic content, followed by a breakthrough recycling enzyme-based process to decompose it into pure monomers in a sustainable way;
• Repolymerization of the recycled monomers into like new plastic;
• Fabrication and quality verification of the new products made of recycled plastic materials

 
WhiteCycle has a global budget of nearly 9.6 million euros and receives European funding in the amount of nearly 7.1 million euros. The consortium’s partners are based in five countries (France, Spain, Germany, Norway and Turkey). Coordinated by Michelin, it has an effective governance system involving a steering committee, an advisory board and a technical support committee.

The FACHPACK in Nuremberg ranks among the most important packaging industry gatherings. From 27 to 29 September 2022, Sappi will be presenting its latest products and solutions for functional paper packaging, flexible packaging papers, label papers, containerboard and paperboard. The company is focusing its efforts on sustainable, recyclable and innovative solutions.

• Wide range of barrier papers in the market for sustainable and recyclable packaging solutions
• High-impact brand presence in corrugated board packaging thanks to Fusion Nature Plus in combination with Fusion Topliner
• Parade Label Pro wet-glue label paper for an efficient operation and an excellent visual impression

Wide range of barrier papers
Sappi’s ultimate goal as a specialist in barrier papers is to replace non-recyclable aluminium and plastic multi-layer laminates through the introduction of truly sustainable alternatives that meet all market requirements in terms of performance and recycling. Sappi is continuously expanding its portfolio of barrier papers. At the show, Sappi will be showcasing several examples of food and non-food applications using these barrier papers.

A smooth surface and a high degree of whiteness: Parade Label Pro
Sappi will also be presenting its new, non-wet-strength wet-glue label paper Parade Label Pro – featuring samples from all over the world. This glossy, double-coated quality paper offers a smooth surface plus a high degree of whiteness. It’s suitable for numerous label and flexible packaging applications, such as labels for disposable bottles, food and non-food containers as well as wrappers for a variety of products. It can be printed in offset, flexo and gravure, and finished with hot foil and blind embossing, for example.

Brand presentation that appeals to the senses
“For manufacturers of branded goods, it is becoming increasingly important to convey brand values and product characteristics in a way that is emotionally appealing and that really sets the stage,” explains Luis Mata, Sales Director Packaging of Sappi Europe. At the FACHPACK, Sappi will also be presenting its containerboard products for corrugated board applications, which, with their brilliant colour reproduction, enhance on-shelf product impact and ensure real brand differentiation.

Sappi’s popular Algro Design paperboard portfolio also allows the design scope and leeway to communicate brand values in an emotionally appealing way.

The adidas TERREX HS¹ is one of the first knitted products to be made in part with Spinnova technology. At least 30% of the fabric in this mid-layer hiking hoodie comes from wood-based SPINNOVA® fibres (other fibres)* and 70% from cotton (organic).

Adidas is committed to helping End Plastic Waste via a three-loop strategy that consists of using recycled materials, materials that can be made to be remade and in the case of Made with Nature, products created in part with natural ingredients, such as the adidas TERREX HS¹.  

The first product to emerge from this partnership, the adidas TERREX HS¹ mid-layer is a piece of multi-functional gear that works on the trails and then rolls up into its hood for easy storage or to create a pillow on longer adventures. It was designed using UNITEFIT – an all-gender fit system created with a spectrum of sizes, genders, and forms in mind.

Made in part with Spinnova technology , a minimum of 30% of the fabric in the adidas TERREX HS¹ comes from wood-based SPINNOVA® fibres (other fibres)* that are made by grinding wood pulp with water into a paste and then spun into a textile fibre.

The product also works with the material’s natural color. Since no dyeing or bleaching is applied, in turn this uses less water compared to the standard dyeing process.

Carbios has signed an agreement with On, Patagonia, PUMA, and Salomon, to develop solutions that will enhance the recyclability and circularity of their products.
 
An important element of the two-year deal will be to speed up the introduction of Carbios’ biorecycling technology, which constitutes a breakthrough for the textile industry. Carbios and the four companies will also research how products can be recycled, develop solutions to take-back worn polyester items, including sorting and dismantling technologies, and gather data on fiber-to-fiber recycling as well as circularity models.
 
The challenge the four brands share, is that their ambitious sustainable development goals can only partially be met by conventional recycling technologies which mostly target bottle-to-fiber recycling. Future regulations will require more circularity in packaging and textile. Yet the market consensus is that there will soon be a shortage of PET bottles, as they will be used for circular production methods in the Food & Beverage Industry.   
 
Carbios’ innovative process constitutes a technological breakthrough for the recycling of polyester (PET) fibers, which are widely used in apparel, footwear and sportswear, on their own or together with other fibers. PET polyester is the most important fiber for the textile industry with 52 MT produced, even surpassing cotton at 23MT. The biorecycling process uses an enzyme capable of selectively extracting the polyester, recovering it to recreate a virgin fiber. This revolutionary technology makes it possible to recover the PET polyester present in all textile waste that cannot be recycled using traditional technologies.
 
PET plastics and fibers are used to make everyday consumer goods such as bottles, packaging and textiles. Today, most PET is produced from fossil resources, then used and discarded according to a wasteful linear model. By creating a circular economy from used plastics and fibers, Carbios’ biorecycling technology offers a sustainable and more responsible solution.

• 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.”

POWERFIL, a business unit of recycling machine manufacturer EREMA GmbH, presents its 2/406 laserfilter.

"For applications with a focus on melt quality and filtration fineness, this increase in screen area ensures lower pressure and temperature at the same throughput rate, allowing even finer screens to be used for even better results in quality-intensive plastics applications," explains Robert Obermayr, Head of Business Unit POWERFIL, EREMA GmbH. If the throughput capacity of the recycling plant needs to be increased, a significantly higher rate of plastic melt can be filtered while maintaining the other parameters thanks to the larger surface area of the screen. Up to 9,000 kilogrammes of melt can be filtered per hour with the Quattro version of the new LF 406 laserfilter.

"Plastic recycling has become a must-have, even for input streams with higher levels of contamination. Efficient filtration systems are therefore indispensable for achieving the specified melt quality using existing extrusion systems," says Obermayr. That is why POWERFIL also offers the proven EREMA melt filters as individual components for existing EREMA machines and third-party extrusion systems. The product range includes the SW RTF partial area backflush system and the laserfilter. The range is aimed at manufacturers as well as recyclers, because the high-performance filters can be used to process post consumer plastics as well as post industrial films with paper labels and clean PET material. Both types of filter are particularly easy to integrate into an existing recycling plant and both are available in numerous sizes and variations. Whether the customer uses the robust backflush filter or the continuous high-performance laserfilter depends on the throughput and level of contamination of the material. The Laserfilter is ideal for heavy contamination. It handles impurity levels up to 5 percent and filtration as fine as 70 μm while continuously cleaning the screen with a scraper.

POWERFIL will also present the new 2/406 laserfilter and the full range of filters at the K 2022 trade fair stand for the EREMA Group.

TEXAID as a professional collector and sorter with roots in Switzerland contributes to this ecosystem to enable the textile-to-textile recycling.  The creation of Swiss Textile Recycling Ecosystem marks a key milestone in the upscaling of Worn Again Technologies’ recycling process technology with technology scale-up partner Sulzer Chemtech in Winterthur. It also supports its ambition to create a circular economy where non-reusable, hard-to-recycle textiles can be reintroduced into supply chains to become new fibers.

To cause a paradigm shift in the fashion industry and realize true circularity requires all members of the value chain to be on the same page and working towards the same goals. The Swiss Textile Recycling Ecosystem is a network comprising fabric and textile manufacturers, waste collectors and sorters, as well as retailers, brand owners and technology providers – all coordinated by Swiss Textiles. All these parties will cooperate to make their shared vision of a more sustainable fashion industry a reality, where used textiles can be recycled into new textiles.

TEXAID as a stakeholder in the Swiss Textile Recycling Ecosystem and as leading textile recycling company with over 40 years of experience will support the initiative through collecting, sorting, pre-processing and providing pre- and post-consumer feedstock to the Demonstration Plant. At its headquarters in Schattdorf (CH), TEXAID will investigate possibilities to automate the sorting and pre-processing of textile feedstock for recycling. Currently, TEXAID processes more than 80,000 tons of end-of-use textiles and footwear every year all over Europe and the US.

Thermore launches its new product EVOdown®, made of 100% recycled fibers from PET bottles. Thermore EVOdown® bridges the gap between free fibers and traditional padding, delivering the ultra-soft hand and drape of blow-in fibers in a rolled form.

EVOdown® consists of millions of free fibers encapsulated by two containing outer layers. It is light-weighted and has a silky touch.

EVOdown® is another step towards sustainability for the Milan-based company, which has now converted over 97% of its turnover into insulations made of either fully or partially recycled fibers (based on actual sales figures). This brings Thermore closer to an exclusively sustainable product offer. Sustainability has always been part of Thermore’s DNA, as the Group pioneered the use of recycled fibers in the early 80s and mastered it thereafter.

The European Pultrusion Technology Association (EPTA) has published a report from its latest conference, which focuses on advances in sustainability and recycling.

More than 130 professionals from the global pultrusion community gathered at the 16th World Pultrusion Conference in Paris on 5-6 May 2022. Organised by EPTA in collaboration with the American Composites Manufacturers Association (ACMA), the event featured 25 international speakers sharing insight on market trends, developments in materials, processing and simulation technologies, and innovative pultruded applications in key markets such as building and infrastructure, transportation and wind energy.

‘Bio-pultrusion’:  
Composites based on natural fibres offer a number of benefits, including low density and high specific strength, vibration damping, and heat insulation. The German Institutes for Textile and Fiber Research Denkendorf (DITF) are developing pultrusion processes using bio-based resins and natural fibres. Projects include the BioMat Pavilion at the University of Stuttgart, a lightweight structure which combines ‘bamboo-like’ natural fibre-based pultruded profiles with a tensile membrane.

Applications for recycled carbon fibre (rCF):
The use of rCF in composite components has the potential to reduce their cost and carbon footprint. However, it is currently used to a limited extent since manufacturers are uncertain about the technical performance of available rCF products, how to process them, and the actual benefits achievable. Fraunhofer IGCV is partnering with the Institute for Textile Technology (ITA) in the MAI ÖkoCaP project to investigate the technical, ecological and economic benefits of using rCF in different industrial applications. The results will be made available in a web-based app.

Circularity and recycling:
The European Composites Industry Association (EuCIA) is drafting a circularity roadmap for the composites industry. It has collaborated with the European Cement Association (CEMBUREAU) on a position paper for the EU Commission’s Joint Research Centre (JRC) which outlines the benefits of co-processing end-of-life composites in cement manufacturing, a recycling solution that is compliant with the EU’s Waste Framework Directive and in commercial operation in Germany. Initial studies have indicated that co-processing with composites has the potential to reduce the global warming impact of cement manufacture by up to 16%. Technologies to allow recovery of fibre and/or resin from composites are in development but a better understanding of the life cycle assessment (LCA) impact of these processes is essential. EuCIA’s ‘circularity waterfall,’ a proposed priority system for composites circularity, highlights the continued need for co-processing.

Sustainability along the value chain:
Sustainability is essential for the long-term viability of businesses. Resin manufacturer AOC’s actions to improve sustainability include programmes to reduce energy, waste and greenhouse gas emissions from operations, the development of ‘greener’ and low VOC emission resins, ensuring compliance with chemicals legislation such as REACH, and involvement in EuCIA’s waste management initiatives. Its sustainable resins portfolio includes styrene-free and low-styrene formulations and products manufactured using bio-based raw materials and recycled PET.
