From the Sector

Following their entry into the fibres and textiles sector, as announced at K 2022, recycling machine manufacturer EREMA launches the INTAREMA® FibrePro:IV - which has been specially developed for PET fibre-to-fibre recycling - at ITMA in Milan from June 8 to 14. Thanks to its especially gentle material preparation and efficient removal of spinning oils, the rPET produced can be reused in proportions of up to 100 percent for the production of very fine fibres.

PET is regarded as a key material for the production of synthetic fibres. Around two thirds of the total volume of PET goes into the production of PET fibres for the textile industry. This highlights the importance of high-quality recycling solutions for the circular economy. By combining proven INTAREMA® technology with a new IV optimiser, EREMA succeeds in processing shredded PET fibre materials heavily contaminated by spinning oils in such a way that the finest fibres can be produced again from the recycled pellets. The system, which now joins EREMA's machine portfolio as the INTAREMA® FibrePro:IV, is characterised by a longer residence time of the PET melt. This is an essential factor for achieving high quality recycled pellets, as it allows the spinning oils and other additives used to improve the handling of the fibres during manufacturing to be removed more efficiently than in conventional PET recycling processes. Following extrusion, by polycondensation the intrinsic viscosity (IV) of the PET melt is increased in the new IV optimiser and under high vacuum to the precise level that is needed for fibre production. "Including filtration the output quality that we achieve with this recycling process is so high that ultra-fine fibres of up to 2 dtex can be produced using these rPET pellets, with an rPET content of 100 percent," says Markus Huber-Lindinger, Managing Director at EREMA. Waste PET fibre from production processes can therefore be further processed into rPET filament fibre, carpet yarn and staple fibre.

While the focus of the fibre and textiles application is currently still on PET fibre recycling, EREMA is committed to driving forward the recycling of mixed fibre materials from classic textile recycling collection in a next project phase. In order to accelerate development work, the EREMA Group opened its own fibre test centre, where a cross-company team is working on recycling solutions for fibre-to-fibre applications. The centre also operates a fully equipped and variable industrial-scale recycling plant. It includes the peripheral technology required and is available to customers for trials.

KARL MAYER GROUP will be presenting a WEFTTRONIC® II G at the ITMA with new features and upgrades for greater efficiency. This warp knitting machine with weft insertion produces lattice structures from high-strength polyester, which are firmly established in the construction industry in particular. With a working width of 213", it offers productivity and further advantages through design innovations. New features include weft thread tension monitoring, management and the new VARIO WEFT laying system. The component for the weft insertion aims at maximum flexibility. It allows the patterning of the weft yarn to be changed quickly and easily electronically, without mechanical intervention during yarn insertion and without limits on repeat lengths. In addition, there is less waste.

The KARL MAYER GROUP also supports its customers with well thought-out Care Solutions. The new support offers include retrofit packages for retrofitting control and drive technology for weft insertion and composite machines, and service packages that bundle various services. These include machine inspections and the replacement of all drive belts. The customer benefits from fixed prices that cover the costs of technician assignments, various discount options and transparent services.

A new solution for the vertical greening of cities is presented from the field of application for technical textiles. The core of the innovation is a grid textile produced on warp knitting machines with weft insertion by KARL MAYER Technische Textilien GmbH. The knitted lattice fabric is made of flax. It is used as a climbing aid for fast-growing plants, and after the greening phase, in autumn, it can be recycled together with these plants as biomass in pyrolysis plants to produce electricity and activated carbon. In summer, the planted sails lower the ambient temperature through evaporation effects. In addition, photosynthesis creates fresh air and binds CO2. Other important advantages are low soil requirements and flexible placement in public spaces. The greening system was developed by the company Micro Climate Cultivation, OMC°C, with the support of KARL MAYER Technische Textilien.

The KARL MAYER GROUP will also be exhibiting a sustainable composite solution made from natural fibres. The reinforcing textile of the innovative lightweight material is a multiaxial non-crimp fabric, which was also produced from the bio-based raw material flax on a COP MAX 4 from KARL MAYER Technische Textilien. The boatbuilding specialist GREENBOATS uses natural fibre composites to achieve sustainable products. The fact that it succeeds in this is shown, for example, by the Global Warming Potential (GWP): 0.48 kg of CO2 per kilogram of flax reinforcement compares with 2.9 kg of CO2 per kilogram of glass textile.

ERCA, Patagonia® and YKK announce the implementation of ERCA’s REVECOL®, a sustainable, innovative chemical agent, in YKK’s dyeing processes at their Vietnam production sites transforms common waste material, such as exhausted vegetable cooking oil, into an upcycled, certified high performance, safe textile chemical. ERCA has invested in circular practices to take waste material and use them as feedstocks to create new responsible chemical products.

Always searching for new sustainable innovations, REVECOL® caught the attention of Patagonia®. Driven by the goal to utilize non-extractive chemistry in their supply chain wherever possible, the brand teamed up with ERCA and trim supplier YKK to deploy REVECOL®.

REVECOL® LV-TS has a carbon footprint that is 72% lower* than the more conventional chemical auxiliaries produced by ERCA. Today ERCA produces a wide range of high-performance chemical auxiliaries made from used vegetable oil that are ZDHC, bluesign® approved and GRS certified.

ERCA is one of the first companies to have GRS certified chemical products, opening the door to circular chemical auxiliaries.

As part of their Sustainability Vision 2050, YKK is constantly working to deploy more sustainable chemical processes in their production. The ability to replace a commonly used dye chemical with a lower impact version was a no-brainer for YKK’s Vietnam management. REVECOL® is not only more sustainable, it is also more efficient, reducing the use of the dyeing auxiliary by 20% to 30%, thus  helping to lower YKK’s overall chemical usage.

B.I.G. Yarns unveils its new “SustainableYarns” platform, with Clerkenwell Design Week visitors the first to be invited to get on board and focus on what matters most for the design and manufacture of sustainable soft floorings.

The expert in polyamide (PA) 1 step 3 ply yarns offers a range of options for manufacturers to introduce sustainable yarns into carpet solutions and reach sustainability targets faster and more efficiently.

The Sustainable Yarns range creates opportunities to design with recycled content yarn (EqoCycle), to work with renewable resources (EqoBalance), and, following the launch of new polyamide 6 (PA6) EqoYarn at Clerkenwell Design Week, to also leverage the low-impact value chain.

New addition EqoYarn is a new low-impact PA6 carpet yarn based on the most recent innovations in polymer production, which enable yarn manufacturers to lower their carbon footprint by nearly 50% and give carpet manufacturers more options to reduce their impact.

For its EqoYarn Bulk Continuous Filament (BCF) production process, B.I.G. Yarns has selected the few best-in-class partners that have made major steps forward in terms of sustainability, and reduced their greenhouse gas emissions thanks to continuous investments in process efficiency, green energy, heat optimization and waste reduction. The result is EqoYarn with a carbon footprint of 4 kg CO2 eq/kg yarns, which is a CO2 reduction of up to 50% compared to conventional PA yarns.

EqoBalance PA6 yarns enable customers to reach an even higher CO2 reduction of up to 75%. Manufactured with polymers made from renewable resources such as organic waste from cooking oil instead of virgin or fossil feedstock, these yarns have a carbon footprint of 1.98 kg CO2 eq./ kg yarns. They help carpet manufacturers to create products with an extremely low carbon footprint.

EqoCycle PA6 yarns are fully recyclable and incorporate 75% recycled content originating from recycled and regenerated PA6 granules. With a carbon footprint of 4.64 kg CO2 eq./ kg yarns, they deliver the same high-quality performance of virgin PA6 yarn with the benefit of 37% CO2 reduction. EqoCycle yarns offer carpet manufacturers a sustainable alternative to help reduce the ecological footprint of their products and move towards a circular economy without jeopardizing the end-product quality.

In addition to the different CO2-reducing options, B.I.G. Yarns’ customers can access an unlimited colour range to elevate their designs. Its BCF technology for polyamide yarns, twisted and heat-set yarns, one-colour to multi-colour, between 650 and 15000 dTex, along with its colour studio, are available to support their creation of customised collections.

• Carbios has developed an ultra-high throughput microfluidic screening of PET-depolymerizing enzymes in partnership with the Paul Pascal Research Center^[1], a joint research unit of the CNRS^[2] and the University of Bordeaux
• Microfluidics enables millions of enzymes to be screened in a day, compared with a few thousand a week with conventional technologies
• Future polymers of interest will benefit from this acceleration of the R&D phase, enabling Carbios to develop its portfolio of innovations on different types of plastic more rapidly

Carbios has accelerated its enzyme screening process with a microfluidic technology developed in partnership with the Paul Pascal Research Centre (a joint research unit of the CNRS and the University of Bordeaux, which specializes in microfluidics). This technology enables the screening of millions of enzymes in just one day, speeding up the process to optimize enzymes breaking down PET. This competitive advantage enables Carbios to reduce the time between the R&D phase and the production of its proprietary enzymes, and therefore to develop concrete solutions to plastic pollution even faster.

Microfluidics
Microfluidics allows the production of devices handling very small amounts of liquid. Each droplet generated can be considered as an independent microreactor having a volume in the picoliter range (10-12 liters) and containing a particular enzyme whose PET depolymerization activity will be screened. These droplets move through analysis units the size of a microchip allowing ultra-high throughput screening of 150 enzymes per second.

Previously, conventional robotic systems allowed screening in microplate format with a volume in the milliliter range (10-3 liters) and with rates of around one enzyme per minute.

The use of microfluidics to screen for more efficient or new enzymes will become widely adopted in the coming years, therefore accelerating the development of bioprocessing. Currently used by Carbios for the development of its PET depolymerization process, microfluidics should be used to accelerate the development of new enzymes for other types of plastic such as polyamide.

Carbios researchers specialized in microfluidics
Microfluidic processes require special expertise. At present, two researchers at Carbios are dedicated to microfluidics and based in the cooperative laboratory with TBI^[3] hosted by INSA^[4] Toulouse.  Alexandra Tauzin, Researcher in Enzyme Engineering and Microfluidics, and Alexandre Gilles, Engineer specialized in robotics, work in partnership with the Paul Pascal Research Center.

Around EUR 355 million in overall turnover, 350 extruders delivered creating an additional recycling capacity for 1.6 million tons of recycled pellets as a result - these are the figures with which the EREMA Group was able to close the 2022/23 financial year in March.

"With demand for recycled plastics remaining high, the past financial year brought many challenges that we needed to handle," says Manfred Hackl, CEO of EREMA Group GmbH. The challenges included persistent delays in the supply chain and unexpected supplier outages. Logistics and production processes had to be adapted several times as a result. The situation has improved significantly meantime as a result of these measures and more stable supply chains.

The production locations in Austria manufactured 270 extruders and delivered them to customers around the globe. Taking the whole group into consideration, this figure rises to 350 including the extruders from PLASMAC, the Italian subsidiary. The recycled pellet production capacity of all extrusion systems delivered in financial year 2022/23 adds up to around 1.6 million tonnes per year. On top of that there are around 130 additional components and modules such as filter systems and ReFresher anti-odour units.

Recycling innovations for high-quality pellets
K 2022 - the highlight trade fair of the past financial year - saw the EREMA Group launch seven
new recycling systems and components. These included the new INTAREMA® TVEplus® DuaFil® Compact recycling system and the EcoGentle® plasticising unit, which was also newly developed. Thanks to their gentle polymer treatment and significantly lower melt temperature, both extrusion innovations deliver effective advantages in terms of the quality of the melt, recycled pellets, and final product, as well as impressive energy efficiency in post consumer and PET recycling applications. The significance of these innovations for plastics recycling is underlined by the nomination of the DuaFil® Compact technology for one of this year's Plastics Recycling Awards Europe in the category Recycling Machinery Innovation of the Year.
The same applies to the READYMAC 1109 TVE machine made to stock by EREMA Group subsidiary UMAC, as well as to the new ALPHA XS edge trim recycling machine for the inhouse recycling segment made by PLASMAC. The market launch of the deinking system presented at K 2022 by the EREMA Group company KEYCYCLE delivering a throughput of 1,200 kilograms per hour has been a success, as has the commissioning of a further unit sold to a film manufacturer.

40 years of EREMA
The beginning of the new financial year falls almost to the day on EREMA's 40th anniversary. On 14 April 1983, Helmut Bacher, Helmuth Schulz and Georg Wendelin founded EREMA Engineering Recycling Maschinen und Anlagen GesmbH, laying the foundation for the 40-year success story. In celebration, the comapny will hold the event EREMA Discovery Day at the company headquarters on the 1st of June. This event with live insights into the latest post consumer and PET recycling technologies will also see the official opening of the newly built research and development centre.

DyStar announces the plan to restructure its Ludwigshafen facility located in Germany. The strategic decision is made by the company in response to changing business conditions and market shifts.

Mr. Xu Yalin, Managing Director, and President of DyStar Group said, “This is an important strategic move for DyStar. We will focus on developing key emerging markets, which have been shifting over a decade. In the wake of higher energy costs and inflation, DyStar is determined to further improve cost efficiency and drive sustainable productivity as we continue to deliver the highest quality of innovative products that support the global supply chain.”

Mr. Eric Hopmann, Chief Commercial Officer of DyStar Group said, “The restructuring of this facility will be carried out in a phased manner. DyStar will diversify the production activity out of Europe and start with the reduction of manpower as a consequence. DyStar’s customers can be further assured of undisrupted supply, hence their production should not be affected as we will work closely to meet their specific requirements.”

The facility has been an integral part of DyStar’s global network. DyStar inherited this facility from their founders who started the Indigo research and manufacturing more than 125 years ago.

Yanfeng has reached another milestone in its sustainability journey by bringing the power of solar energy to its plants in South Africa. The global automotive supplier already uses renewable energy at all its locations in Europe – some of which are already operating with 100% green energy – and now will supplement its operations in South Africa with sustainable and emission-free solar energy generation.

Many sectors are facing major challenges with the transition to a low-carbon economy. The automotive sector in particular faces many operational and economic challenges when transforming production plants into net-zero emission operations. Thanks to its commitment to sustainability, 100% of the solar energy generated by the PV systems is used to power Yanfeng’s production plants in South Africa, helping them save around 2,559 tons of CO2 annually while reducing their monthly costs and increasing efficiencies.

The solar energy systems were funded by SolarAfrica, which will also operate, maintain and monitor the systems going forward. “From the outset of these projects, Yanfeng’s focus was on reducing their CO2 emissions and SolarAfrica is proud to partner with them to make their journey towards sustainability a success,” said David McDonald, CEO of SolarAfrica. “It’s inspiring to see a global company like Yanfeng invest in world-class facilities in South Africa, contributing to our country’s green economy and supporting job creation in the automotive industry.”
 
All Yanfeng European plants were converted to renewable energy by the beginning of 2022. With this new PV system, Yanfeng has implemented a milestone in the conversion to net-zero emission production at its two plants in South Africa.
