From the Sector

Increasing energy and resource efficiency in the construction sector will be key to the EU’s ambition of achieving climate neutrality by 2050. By enabling the manufacture of strong, durable and lightweight products, composite materials can help the construction sector improve its environmental sustainability, as well as reduce total lifecycle costs. The latest EPTA industry briefing, Pultruded composites contribute to a more sustainable future for construction, discusses how pultruded composites answer the need for materials offering high performance, faster installation, corrosion resistance and low maintenance.

The report is available to download from the EPTA website.

The future of construction
As one of the largest global users of energy and raw materials, the construction industry is under immense pressure to improve its sustainability. At the same time, it must respond to demands for improved performance and reduced total cost of ownership. New materials will be needed to minimise the use of natural resources, enable a reduction of carbon footprint and facilitate circular economy practices. Choosing the optimum materials required for durability throughout the lifecycle will be increasingly important. A shift to off-site production is also forecast, where factory-controlled environments and automated processes can improve quality control, lower waste, and reduce work on site.

Lightweight pultruded parts can be pre-assembled into modules or complete structures in the factory for faster installation on site. Lightweight profiles lower energy use during transportation and installation, and a longer service life combined with minimal maintenance can deliver a reduced through-life carbon footprint. Pultruded parts such as profiles, gratings, beams, tubes and planks are increasingly found in a range of building, construction and infrastructure applications. Examples include bridge decks, fencing, stairs and handrails, train platforms, cladding, utility poles, modular building concepts, and window frames.

One application offering large growth potential for composites is bridges. Composite bridges are being designed to provide a service life of 100 years and unlike steel bridges do not require regular repainting to protect them from corrosion. Over recent years, pultruded glass fibre composite has become a highly popular choice for pedestrian and cycle bridges. Pre-fabricated ‘easy fit’ bridge decking planks, pre-assembled bridge modules and complete bridge ‘kits’ are now available. Corrosion-resistant composite bridges are ideal for use near water or on the coast, and in remote locations where regular maintenance operations would be difficult. A composite bridge can deliver the same performance as a steel structure with a weight saving of up to 50% or more. This enables more streamlined bridge designs which require less substantial supporting structures and foundations, greatly reducing consumption of materials and energy. Lightweight also results in easier logistics and simplified installation. Pultruded are more easily transported to the construction site, with lower fuel consumption, and easier to move on site, often reducing labour requirements and the capacity of lifting equipment.

A lifecycle approach
As the construction industry looks to the future, the environmental and economic benefits of composite materials linked to easier logistics and installation, durability and low maintenance are becoming increasingly valued. More projects are demonstrating the benefits of composite materials and standards covering the design, fabrication and installation of pultruded profiles are making it easier for the construction industry to use them. With ongoing development and collaboration, pultrusion has the potential to contribute to a more sustainable future for construction and many other industries. EPTA will continue to promote the advancement of pultrusion technology and its applications and foster sustainable practices within the industry.

Bangladesh will stage the world’s first climate conference for the fashion industry this autumn, on 12 October. The Bangladesh Climate Action Forum will convene policy makers, garment manufacturers, fashion retailers and other industry stakeholders to look at solutions for decarbonising global textile supply chains.

The event will focus on technological and financial challenges around reducing emissions. Most of the world’s leading fashion brands have now set ambitious targets for reducing supply chain emissions. These targets relate to 2030 by which time many brands aim to reduce emissions by 50 per cent, and 2050 where most fashion brands aim to be carbon neutral.

The Bangladesh Climate Forum Action will examine causes of climate crisis, its urgency, impacts we have already seen, and what we can expect under both businesses as usual and rapid decarbonisation scenarios.

Also presenting at the event will be the Government of Bangladesh, which will address Bangladesh’s actions to mitigate the impacts of the climate crisis. Bangladesh is particularly vulnerable to climate change and is ranked the seventh extreme disaster risk-prone country in the world according to a report from the Global Climate Risk Index 2021. Tropical cyclones, tornadoes, floods, coastal and riverbank erosion, droughts and landslides are the major climate-induced hazards in Bangladesh.

The Bangladesh Climate Forum Action will also look at approaches towards decarbonization, including NetZero goals and timelines. Speakers will discuss globally recognised pathways for electricity/transportation/industry decarbonisation.

Renewable energy will also be under discussion. If fashion brands are to hit climate targets, it is imperative that supply chains switch to renewable energy and away from gas and fossil fuels. The event will look at challenges around the de-carbonisation of the electricity grid in Bangladesh, as well as the rate of transition toward renewable resources by garment factories, including solar power.

A key element of the event will be evaluation of practical solutions for Bangladesh’s RMG industry. It will profile specific solutions such as energy efficiency, machine upgrades, the electrification of thermal loads, direct power purchase agreements and biomass fed thermal systems. It will also discuss the challenges faced in the industry including business climate (and cycles), pricing, financing challenges, target setting and execution, policy opportunities, knowledge gaps and availability/scaling of solutions.

Financial challenges around decarbonisation of supply chains are significant, and it is far from clear who will pay for the technological upgrades required. While some investment support systems exist – such as lower interest financing – these are not always available, accessible or affordable for the majority of the RMG companies.

The event will explore financial options, changes to business/pricing models, opportunities for de-risking/underwriting investments, direct investment and other tools that need to emerge to address financial challenges and plug the funding gap. The event will also explore opportunities to decouple climate action from business cycles so that the 2030 targets can be met.

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.

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.

• Spunbond, meltblown and composite structures for new market opportunities

RadiciGroup is participating with its Advanced Textile Solutions business area at Index in Geneva from 18 to 21 April 2023. Among the Group’s products showcased are spunbond and meltblown for different application sectors, such as roofing, construction, automotive, HO.RE.CA. and filtration.

“The key message we are bringing to the fair is sustainability,” noted Enrico Buriani, CEO of the Nonwovens division of RadiciGroup Advanced Textile Solutions. “Those who already know us know that, for many years, the Group has been focused on proposing low environmental impact products and processes where sustainability is scientifically measured or certified by independent third parties. Our company is dedicated to nonwovens, which, by the way, are produced using 100% renewable energy. We have expanded our portfolio of innovative solutions for customers interested in realizing projects with sustainability as an essential requirement.”

Respunsible® is a spunbond brand manufactured from recycled polypropylene. A preliminary Life Cycle Assessment (LCA) study was carried out by RadiciGroup to demonstrate the correlation between the reduction in environmental impact and the percentage increase in recycled material. The final results demonstrate that a variable percentage of from 50 to 70% recycled material leads to a reduction in CO2 emissions of from 30 to 40%, compared to a fabric made of 100% virgin material, without comprising high technical performance.

Additionally, since RadiciGroup has achieved ISCC PLUS certification (International Sustainability and Carbon Certification), it can offer bio, biocircular or circular polypropylene spunbond and meltblown nonwovens, in which the sustainable polypropylene is biomass balanced. This certification signifies traceability along the supply chain and verifies that the certified companies meet high environmental and social standards.

“Since 2020, we have had a technologically advanced meltblown production line,” Mr. Buriani concluded. “This allows us to make composite structures, sold under the brand name Radimelt®. Now our goal is to expand our filtration applications, diversifying and developing new business, for instance vacuum cleaner bags or HVAC (heating, ventilation and air conditioning) system filters, where we can meet the high efficiency and mechanical resistance demanded, thanks to our latest generation technology.”

On the sidelines of the Intertextile Shanghai fair, the Swedish textile-to-textile recycling innovator Renewcell and the leading Chinese viscose manufacturer Tangshan Sanyou announced the next step in their partnership to make fashion circular that stretches back to 2018.

The two companies’ new shared ambition is to offer manufacturers and brands Circulose® viscose fibers made from 100% recycled textiles in commercial quantities starting in 2024. The collaboration has been facilitated by Ekman Group, Renewcell’s exclusive global trading partner.

“I am very happy to announce this acceleration of our long-standing partnership with Tangshan Sanyou. They were the first commercial producer of Circulose®-based fibers in the world, and the first to commit to sourcing significant volumes from us. Now, they aim to also be the first to commercialize 100% Circulose® content fibers” said Patrik Lundström, CEO of Renewcell, adding "I applaud Tangshan Sanyou’s vision and support to scaling next gen raw materials like Circulose®.”

The announcement, which follows the recent start of deliveries of 100% recycled textile Circulose® pulp from Renewcell’s newly opened Renewcell 1 recycling plant, is the result of successful validation of Circulose®’s quality in production at Tangshan Sanyou’s commercial-scale manufacturing lines. Tangshan Sanyou would strive to finish the mission of producing commercial volumes of 50% Circulose® content fibers during 2023 and work towards achieving the delivery of 100% Circulose® content branded viscose fibers to selected fashion brands and manufacturers starting in 2024. The two companies will cooperate to market the fibers globally using Renewcell’s Circulose® ingredient brand name.

Mr. Zhang Dongbin, Executive Vice General Manager of Tangshan Sanyou Chemical Fiber, says, "Through the collaboration with Renewcell, we have achieved to use Circulose® made from recycled cotton in the production of our viscose fibers, which is great beneficial to improving resource utilization efficiency and lowering carbon footprint of the industry. It has brought a huge impact in the sustainable fashion industry. We will continue putting efforts in forming good interaction between consumers, brands and enterprises, convey the concept of circular sustainable fashion, promote the greening of textile industry, and ensure a more sustainable way to ensure the sustainable development of the textile industry. Protecting the global ecological environment by applying sustainable solutions is our common goal."

• Longer parking times for greater efficiency

Since 2018, Oerlikon Barmag has been offering the market’s only currently available concept for high-end home textile applications using the POY and DTY process. The spinning concept with the WINGS HD winding unit in conjunction with an automatic eAFK Big V Multispindle texturing machine manufactures high-titer yarns with maximum machine efficiency.
 
“We have correspondingly modified WINGS HD in order to once again better align the increased requirements of these special yarns to the spinning process and make everyday production even simpler for our customers”, comments Stephan Faulstich, POY Process Technology Manager. The parking times are extremely short when winding high titers. We have increased the parking times by up to three times in the case of the new WINGS HD models. To this end, the parking time for a 300d/384f yarn, for example, has been increased from a standard 6.5 min. to 15.7 min. – and, in the case of a 400d/192f yarn, from 4.3 min. to 10.3 min. This makes the doffing process more even, hence increasing doffing reliability.

At the same time, the draw unit now has a more flexible design, meaning that two-godet operation is also possible in the case of products with low overall titers. This has a positive impact on the winding unit’s energy consumption.

12 POY packages of up to 600d/576f (final) are produced in the spinning process using WINGS HD 1800. This is made possible as a result of an additional godet, which ensures that the high yarn tensions developing in the process are reduced to the yarn tensions common in the case of the winding process to date. At the same time, the newly-developed suction unit with the accompanying yarn cut-ting device (yarn collecting system) ensures – both during string-up and in the event of a yarn break – reliable handling of the yarn with an overall titer of 7,200 den (final).

Whereas DTY yarns up to 1,200 den and with up to 784 filaments have in the past, as standard, been plied from four POY 300d/192f bobbins using DTY machines, high titers can also be manufactured directly using the WINGS HD take-up machine. Combining the WINGS HD and the eAFK Big V allows all available winding positions to be utilized during texturing.

By using a high share of recycled content in its Evolon® materials, Freudenberg Performance Materials (Freudenberg) offers technical packaging textiles with a carbon footprint decreased by 35%. An independent LCA study showed additional benefits such as energy resource savings and lower water use. Furthermore, Evolon® fabrics provide sustainability benefits over the packaging entire life cycle thanks to high end performance and durability.

By replacing virgin PET with recycled PET, the cradle-to-gate carbon footprint of Evolon® packaging textile materials decreased by 35%. This is the result of a study by an independent LCA and eco-design consultancy firm, which made a Cradle-to-Gate assessment of several Evolon® products using virgin PET or recycled PET. The study was finalized in 2022 and conducted according to the principles of ISO 14040/ ISO 14044 standards, following the recommendations of the Product Environmental Footprint and the Circular Footprint Formula.

Evolon® microfilament textiles have a small carbon footprint because their manufacturing process uses low CO2 energy sources. The fabrics are lightweight and can be reused throughout entire production programs, e.g. of a car model when it is about the automotive industry. Furthermore, the new Evolon® RE fabrics contain up to 85% of recycled PET which is produced in-house out of post-consumer PET bottles.

Evolon® textiles are suitable for reusable technical packaging, which eliminate the use of thousands of disposable packaging materials. Evolon® fabrics offer scratch-free, lint-free, high-end surface protection for molded plastic parts, painted parts and other sensitive industrial and automotive parts during transport. This contributes to lower the scrap rate of parts and provide both financial and ecological benefits. By using Evolon® reusable packaging to transport highly-sensitive parts, customers can increase their efficiency and save resources.
