From the Sector

The Organic Cotton & Textiles Conference, taking place in Indore, India over three days, from February 27-March 1^st is set to bring together a diverse group of key players from every part of the textile supply chain. Farmers, farm groups, industry representatives, non-profits, academics, suppliers, brands, certifiers, government representatives and policymakers will join nearly 200 guests at the multi-day event. The aim is to foster collaboration, explore innovative ideas, listen to those on the ground and focus discussions to develop a shared vision to boost the organic textile supply chain worldwide.

Co-hosted by  OCA, GOTS, and IFOAM - Organics International, the conference will address a range of subjects including social conditions, transparency through innovation, scaling up organic through investment, as well as sessions tackling certification, decent work and environmental impacts. The event also gives voice to farmers, who join as panellists, in a dedicated Q&A session with seven organic cotton farmers from the region. On the third day, organised by OCA, the organic farmers will welcome attendees to their communities during field trips west to Petlawad to witness organic practices at ground level.

“By addressing these important issues and fostering a dialogue between participants, the conference aims to develop innovative solutions that can drive progress and growth in the sector", says Bart Vollaard, Executive Director of OCA. "We are thrilled to be joining forces with GOTS and IFOAM to create positive change in the organic textile sector."

“Together with IFOAM - Organics International and OCA, GOTS wants to increase visibility of organic and at the same time enhance integrity of organic fibres and textiles. This conference shall serve to strengthen the sector by addressing obstacles and work on effective solutions, in consultation with all relevant and committed stakeholders”, notes Claudia Kersten, Managing Director of GOTS.

Sarah Compson of the IFOAM - Organics International World Board adds “Organic agriculture directly addresses some of the most pressing challenges of our time. IFOAM - Organics International is delighted to collaborate with OCA and GOTS to bring together people from across the whole textile sector and address the barriers and opportunities for scaling organic cotton production worldwide.”

With a strong line-up of notable speakers and guests in a supportive and engaging atmosphere, and a unique approach that connects participants from every step of the supply chain, the Organic Cotton & Textiles Conference is set to be a valuable and transformative event for key stakeholders involved in the organic textile industry.

Valérius 360 wanted to make a sustainable, circular approach possible in the fashion industry. Working together with Trützschler, a collaborative project has now achieved high-quality recycled yarn – opening up massive potential to drive measurable progress toward a circular and sustainable textile industry.

Testing at the Trützschler Technical Center
The team from Valérius 360 wanted to find ways of improving the processes for yarns made from 50 % recycled and 50 % virgin cotton (Ne30). In particular, it was seeking ways to reduce thick and thin spots, which disturb the appearance of the textile surface.

At the Trützschler Technical Center in Mönchengladbach, they conducted special trials that showed that using a direct spinning process for this application delivers much better results than a process with a draw frame passage for rotor yarns.

In direct spinning, the sliver from the card is directly drawn in the draw frame which is integrated in the can stock. This involves one less process step than using an autoleveller draw frame, while also saving space and giving staff more time for other operations.

On-site support from Trützschler Customer Service
The team from Valérius 360 also received in-house training from the Trützschler Customer Service department. Together, they analyzed and significantly improved the process at the Valérius 360 production site. This helped to bring yarns made from recycled raw materials up to the required level of the 50% Usterstatistics. This is the reference level for yarns made from virgin raw materials. Accordingly, 50 % of all yarn producers with raw cotton for rotor yarns and comparable yarn counts produce a poorer quality.

The Swedish textile-to-textile recycling company Renewcell has signed a Letter of Intent with Eastman, a leading US cellulosic acetate fiber producer, for a collaboration to develop Naia™ Renew ES yarns sourced from Circulose®, Renewcell’s 100% recycled textile raw material. The agreement is Renewcell’s first with a US-based fiber producer and an important step in developing the first acetate-based applications to use Circulose® feedstock.

”Eastman considering Circulose® as a feedstock in the production of a premium yarn like Naia™ Renew reflects very well on the Renewcell team’s ability to work with partners to adjust and optimize our product for new fiber applications. This agreement signals an acceleration of our joint efforts to bring Naia™ Renew ES yarns derived from Circulose® to market. I look forward to working alongside Eastman in making fashion circular.” comments Patrik Lundström, CEO of Renewcell.

Ruth Farell, GM of Eastman Textiles says: ”we are thrilled to collaborate with a pioneeer such as Renewcell to lower our reliance on virgin feedstocks, redefine the essence of textile waste and close the loop within the textiles industry. This collaboration is at the heart of our strategy to launch a portfolio of products with increased recycled content”

The textile industry is the third largest consumer of plastics. While growth rates in the production of fibres and textiles are high, the circular economy has hardly become established in this segment. The EREMA Group is now intensifying development of recycling solutions for this application with their new fibres and textiles business unit. Currently, the focus is on PET fibre materials from fibre production and subsequent processing steps. Technologies for recycling mixed fibre textiles from textile collection sources are to follow in a follow-up project phase.

"With EREMA's VACUREMA® and INTAREMA® technology and PURE LOOP's ISEC evo technology, our company group already has an extensive range of machines for fibre and PET recycling applications. For ecologically and economically sound recycling, however, new technological solutions are needed to use the recycled fibres in higher-value end applications and to achieve a functioning circular economy," explains Wolfgang Hermann, Business Development Manager Application Fibres & Textiles, EREMA Group GmbH. The initial focus will be on PET, regarded as a key material for the production of synthetic fibres. The aim is to find recycling solutions that allow PET fibre materials to be prepared for reuse in PET fibre production processes. This is a significant step for the circular economy because PET fibres in textiles account for about two-thirds of the total volume of PET.

In this development work, the EREMA Group can build on existing know-how. Proven recycling technologies have been combined with a new IV optimiser. "This extends the residence time of the PET melt, which is particularly necessary in fibre recycling to efficiently remove spinning oils. Our recycling process also increases the IV value of the PET melt after extrusion back to the specific level that is essential for production of the fibre," explains Hermann. Waste PET fibre from production processes can therefore be further processed into rPET filament fibre, carpet yarn and staple fibre.

Fibre test centre with plant to test customers' materials
In order to accelerate development work, EREMA opened its own fibre test centre a few months ago, where a cross-company team is working on recycling solutions for fibre-to-fibre applications.

The future of e-mobility will be determined in particular by safe battery enclosures. As batteries for electric vehicles become more performant, higher volumetric energy density plays a crucial role. If more energy is to be stored in less installation space, new material and design solutions are required. The development of suitable enclosures made of safe and highly robust lightweight materials is also required. This is a case for the Aachen Centre for Integrative Lightweight Production (AZL). A project on cell-to-pack battery enclosures for battery-electric vehicles, which has been eagerly awaited in the industry, will start in October this year there.

The design of battery housings is crucial for safety, capacity, performance, and economics. The Cell-to-Pack project, which is starting now, will focus on developing concepts for structural components and for producing them based on a variety of materials and design approaches. The concepts will be compared in terms of performance, weight and production costs, creating new know-how for OEMs, producers and their suppliers throughout the battery vehicle value chain. Companies are now invited to participate in this new cross-industry project to develop battery enclosure concepts for the promising and trend-setting cell-to-pack technology.

The basis for the project is the lightweight engineering expertise of the AZL experts, which they have already demonstrated in previous projects for multi-material solutions for module-based battery housings. Together with 46 industry partners, including Audi, Asahi Kasei, Covestro, DSM, EconCore, Faurecia, Hutchinson, Johns Manville, Magna, Marelli and Teijin, 20 different multi-material concepts were optimized in terms of weight and cost and compared with a reference component made from aluminum. All production steps were modelled in detail to obtain reliable cost estimates for each variant. Result: depending on the concept, 20% weight or 36% cost savings potential could be identified by using multi-material composites compared to the established aluminum reference.

It is expected that the design concept of battery enclosures will develop in the direction of a more efficient layout. In this case, the cells are no longer combined in modules in additional production steps, but are integrated directly into the battery housing. The elimination of battery modules and the improved, weight-saving use of space will allow for higher packing density, reduced overall height and cost saving. In addition, various levels of structural integration of the battery housing into the body structure are expected. These new designs bring specific challenges, including ensuring protection of the battery cells from external damage and fire protection. In addition, different recyclability and repair requirements may significantly impact future designs. How the different material and structural options for future generations of battery enclosures for the cell-to-pack technology might look like and how they compare in terms of cost and environmental impact will be investigated in the new AZL project. In addition to the material and production concepts from the concept study for module-based battery enclosures, results from a currently ongoing benchmarking of different materials for the impact protection plate and a new method for determining mechanical properties during a fire test will also be incorporated.

The project will start on October 27, 2022 with a kick-off meeting of the consortium, interested companies can still apply for participation until then.

• Gradual transformation of production capacities to LENZING™ ECOVERO™ and VEOCEL™ branded specialty viscose

The Lenzing Group, provider of wood-based specialty fibers, is expanding its global clean electricity portfolio and transitioning its production site in Purwakarta to green electricity. The Indonesian subsidiary PT. South Pacific Viscose (SPV) has been using electricity generated solely from renewable sources since July this year, which will reduce its specific carbon emissions by 75,000 tonnes annually.

In 2019, Lenzing became the first fiber producer to set a target of halving its carbon emissions by 2030 and becoming climate neutral by 2050. This carbon reduction target has been recognized by the Science Based Targets Initiative. In Purwakarta, Lenzing is currently investing in the reduction of carbon emissions, as well as air and water emissions. Thanks to its EUR 100 million investment in this area, Lenzing is gradually transitioning its existing capacities for standard viscose to LENZING™ ECOVERO™ and VEOCEL™ branded specialty viscose.

“Demand for our wood-based, biodegradable specialty fibers is constantly rising. We see enormous growth potential, especially in Asia. The switch to green, renewable electricity marks a huge step forward in converting our Indonesian site into a specialty fiber supplier. This makes us better positioned to meet the growing demand for sustainably produced fibers,” comments Robert van de Kerkhof, Chief Commercial Officer for Fiber at Lenzing.

The company aims to generate more than 75 percent of its fiber revenue from the wood-based, biodegradable specialty fibers business under the TENCEL™, LENZING™ ECOVERO™ and VEOCEL™ brands by 2024. With the launch of the lyocell plant in Thailand in March 2022 and the investments in existing production sites in Indonesia and China, the share of specialty fibers in Lenzing’s fiber revenue is set to exceed the 75 percent target by a significant margin as early as 2023.

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.

Lenzing – In the first quarter of 2022, the Lenzing Group, like the entire manufacturing industry, was significantly affected by the extreme developments in global energy and commodity markets. A predominantly positive market environment and the strategic focus on specialty fibers such as those of the TENCEL™, LENZING™ ECOVERO™ and VEOCEL™ brands nevertheless ensured a solid revenue and earnings trend, with the effect of higher costs being largely offset.

• 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.
