• Hightech textiles for future-oriented construction projects

Building shells, bridges, staircases, façades ... construction projects are exposed to enormous mechanical loads. Often there are also considerable climatic or environmental influences. This has prompted the increasing use of fibre-reinforced materials in construction projects. After all, besides many other exciting properties, they offer high mechanical rigidity, low weight and excellent corrosion resistance.

Tapes, tubulars, sections and 3D woven textiles by vombaur form the perfect basis for these innovative building materials. The seamless round or shaped woven narrow textiles made of high-performance fibres are extremely loadable because they have neither seams nor welds – and therefore no undesirable breaking points. Their surface properties are identical over the entire length. In challenging tasks, composite textiles by vombaur offer a lightweight solution that is as reliable as it is durable.

Safe and durable solutions for challenging applications
The potential applications for lightweight components in the construction industry are as numerous as the project ideas of the planning and construction teams.
•    Ropes and tensioning elements made of carbon fibre reinforced plastic (CFRP)
•    Reinforcement of building structures made of concrete, steel, wood or other materials
•    Sustainable restructuring of constructions and urban districts for bridges and buildings
•    CFC slats as reinforcements in case of repairs
•    (Filled) GRP pipes made of seamless round woven tubes by vombaur as columns/pillars
•    CFRP sections as steel girder substitutes
•    Hollow profiles with individually designed cross-sections
•    Glass fibre reinforced connecting elements for glazing to minimise expansion differences between the connecting element and the glass
•    Individual light wells

DyStar is pleased to announce the release of its eleventh annual Sustainability Performance Report. The report is written in accordance with the GRI Standards: Core option, while using the Integrated Reporting <IR> framework to communicate how DyStar drives value creation across multiple stakeholder groups in six capital categories, namely financial, manufactured, intellectual, natural, human capital and social capital.

In FY2020, COVID-19 has continued to present its challenges, such as the shortage of raw materials and rising freight costs. Gloomy global demand has also resulted in some raw and product material wastage in production plants worldwide, leading to increased non-hazardous waste output for FY2020. DyStar recognizes these global factors in play and will continue to make active efforts within the organization’s capability to reduce its environmental footprint in the years ahead.

The Group has set its sight on achieving the 2025 sustainability target of reducing its production footprint by 30% from 2011 levels for every ton of production. “We will continue to innovate and develop a wide range of products and processes that improve environmental performance and reduce carbon footprint across our value chain”, said Mr Xu Yalin, Executive Board Director of DyStar Group.

Mr Eric Hopmann, CEO of DyStar Group added: “We are also developing various projects in anticipation of future demands from customers as well as adopting more environmentally friendly technologies and improve our workflows and processes. Some of our projects include traceability programs, adopting renewable energy technologies, and digitalizing our business processes.” Understanding the importance of collaborative efforts to drive sustainability across the value chain, DyStar seeks to continually support industrial innovations and develop strategic partnerships to work towards becoming a sustainable and trusted leader in the industry.

Buildings are responsible for approximately 40% of all energy consumption and 36% of CO2 emissions in the EU. Improving energy efficiency in buildings therefore has a key role to play in achieving the ambitious goal of carbon neutrality by 2050 set out in the European Green Deal. A new briefing from the European Pultrusion Technology Association (EPTA) discusses how composite materials can help improve the thermal performance of the building envelope to satisfy increasingly stringent energy efficiency regulations. The EPTA report, Opportunities for pultruded composites in energy-efficient buildings, explains how pultruded profiles offer durable,  low maintenance solutions which can help reduce both operational and embodied carbon emissions from buildings in applications including energy-saving windows, thermal break connectors, and solar shading and cladding systems.   

“Economic and population growth mean energy demand is set to rise, making energy efficiency measures even more critical,“ comments Dr Elmar Witten, Secretary of EPTA. “Regulations and standards will continue to push for lower U-values for building elements, driving the increase use of materials and designs which minimise operational carbon emissions. Pultruded profiles offer an attractive combination of properties for designers of energy-efficient buildings – low thermal conductivity to minimise thermal bridging, together with excellent mechanical performance, durability, and design freedom.“  
 
It is estimated that today, roughly 75% of the EU building stock is energy inefficient, meaning that a large part of the energy used goes to waste. This energy loss can be minimised by improving existing buildings and striving for smart solutions and energy efficient materials for new builds. Areas of focus include improving glazing systems, better insulation of envelope components, and reducing unwanted solar heat gains. The low thermal conductivity of composites is being exploited in components and structures that help to minimise energy required for space conditioning.

Lenzing presented at FILO its sustainable approach and on a selection of key innovations such as TENCEL™-branded specialty fibers.

As part of the space dedicated to Cittadellarte – Fondazione Pistoletto and Fashion B.E.S.T., the first Italian collective of responsible fashion designers, a selection of TENCEL™’s key technologies were under the spotlight:

• TENCEL™ x REFIBRA™, using cotton textile waste and wood pulp as the feedstock for cellulosic fibers, creating a circular solution;
• TENCEL™ x Indigo Color, infusing pigment into fibers directly during the spinning process;
• TENCEL™ Luxe, providing superior aesthetics, performance and comfort to be the perfect partner of other noble fibers such as silk, cashmere or wool;
• TENCEL™ Carbon Zero, offering carbon-zero CarbonNeutral®-certified products by Natural Capital Partners;
• TENCEL™ x Eco Clean, bringing totally chlorine-free-bleached TENCEL™ Modal fibers to the textile industry.

Lenzing's priority has been to produce fibers for many sectors (fashion, beauty care, cleaning, hygiene and home textiles) in a sustainable way. Each Lenzing product is made of cellulose from wood, a renewable natural resource, coming only from certified sustainable sources.
The Lenzing Group operates two commercial-scale biorefineries with 100% wood utilization, which ensure that the totality of wood constituents are used to produce fibers, biobased chemicals, and bioenergy, thus maximizing value creation from an economic and environmental perspective. This concept was illustrated by Carlo Covini, Lenzing Business Development Manager Italy & Switzerland, in his presentation “Lenzing’s biorefinery concept”.

Notus Composites (UAE), the award-winning producer of epoxy prepreg materials, announces the latest addition to its high-performance epoxy range with the launch of its new NE7 low temperature curing prepreg system. The Notus NE7 formulation allows composite manufacturers to cure components at temperatures as low as 70˚C, reducing energy consumption and enabling more cost-effective tooling options.

Notus Composites has developed the new NE7 prepreg systems for applications across the Marine, Architecture, Industrial and Wind Energy sectors, with the novel low temperature curing chemistry delivery significant cost benefits. Existing prepreg manufacturers can now use more cost-effective composite tooling, with new prepreg users able to switch easily from existing infusion or wet laminating processes without creating expensive new high temperature tooling.

NE7 prepregs can be cured at temperatures as low as 70˚C, with the standard cure cycle being 12 hours at 70˚C, matching the typical cycle time for an infused part with a component Tg of 85˚C. NE7 materials have a good outlife of 30 days at 20˚C and are available in all prepreg and Notus single sided N1-Preg formats with unidirectional, multiaxial, and woven reinforcements. NE7 can also be supplied as a resin film.

Notus has recently supplied NE7 low temperature prepregs to Dubai based Aeolos Composites for the production of their new Aeolos P30 racing yacht. The P30 is a futuristic new craft created by top German sailor and designer, Hans Genthe, with a super light carbon fibre construction and large sail area that promises spectacular on the water performance for a thirty foot yacht. Notus delivered a range NE7 prepregs for the build, including woven, multiaxial, and unidirectional carbon fibre reinforcements as well as adhesive films for core bonding.

As one of the driving forces helping to create a fully circular fashion industry, ISKO has partnered with Swedish research and development company MoRe Research, a part of RISE Research Institutes of Sweden, to investigate and develop new, sustainable technologies made from cellulosic-based materials, derived from waste textiles, for the company’s 25,000+ range of products. It is hoped that this research will also help make the production of cellulose-based materials more sustainable.

The work with MoRe Research feeds into ISKO’s Responsible Innovation™ strategy and will link with various sustainability projects the company is working on. For example, ISKO recently signed an agreement with HKRITA to license its Green Machine – a unique technology that fully separates and recycles cotton and polyester blends at scale.

ISKO will leverage MoRe Research!s expertise and resources to find ways of repurposing the clean and toxic-free cellulose powders that are created from the decomposed cotton, as well as the recycled polyester and reintegrate this back into fabric production. By using all of the outputs from the recycling of textiles back into textiles, the prospect of a closed-loop system becomes more feasible.

The investment in this new technology is the latest in ISKO’s ongoing drive for advancements in sustainability. As part of the company’s R-TWO™ program ISKO is also working to develop fabrics with a guaranteed minimum +50% GRS (Global Recycle Standard) recycled content blend. This will significantly reduce the carbon and water footprint of a fabric, as well as make it easy to trace a garment’s sustainable journey step-by-step from the beginning of the supply chain through to the end product.

• From fossil to renewable materials: Members advocate policy analysis and focused implementation of the renewable carbon strategy

The members of the Renewable Carbon Initiative (RCI) (www.renewable-carbon-initiative.com), founded in September 2020, have joined forces to shape the transition from the fossil to the renewable age for the chemical and materials industry. This means spreading the concept of renewable carbon and developing new value chains based on renewable carbon as a feedstock.

In the meantime, several activities have started from which future members can benefit as well. First and foremost is the kick-off to comprehensive policy analysis. What influence will forthcoming regulation have on chemicals, plastics, and other materials? When and where should the renewable carbon idea be emphasized and referred to?

The policy analysis will examine pending policies in the European Union – and a later expansion to America and Asia is planned as well.

A particular focus will be placed on upcoming policies and regulations and how they impact renewable carbon. The members are currently deciding on where to start specifically, but questions that may be considered are: What does the new climate law and the “Fit for 55-Package” mean for chemicals and materials? What can be expected from REACH and microplastics restrictions? How relevant is the “Sustainable Products Initiative” and the coming restrictions for Green Claims? Circular Economy, Zero Pollution and Sustainable Financing are keywords of the future European landscapes, which might become very concrete for chemistry and materials in the next few years. To what extent the concept of renewable carbon for materials is considered in policy already and how it could be further introduced in future legislation are two of the main questions investigated in the working group “Policy”.

This working group is open to all members of RCI. Policy experts provide the respective analysis as a foundation, organising discussions between members of the policy group and plan meetings with policymakers to introduce the Renewable Carbon concept.

Additional working groups have been created, one with a focus on communication, the other looking at the development of a renewable carbon label. In early September, a renewable carbon community will be launched as a starting point for even more interaction between the members, to discuss strategies, create new value chains and start project consortia.

The Renewable Carbon Initiative (RCI) is a dynamic and ambitious group of interested parties. Membership numbers have now more than doubled since the launch almost a year ago, with RCI now boasting 25 members, 6 partners and over 200 supporters. It welcomes all companies that are on the way to transform their resource base from fossil to renewable.

• Call for Papers and Posters

More than 200 leading international experts in Carbon Capture and Carbon Utilisation (Power-to-X) together with 20 exhibitors are expected to attend the hybrid event on 23–24 March 2022, in Cologne, Germany

Main topics of the conference are strategy & policy in CCU, renewable energy and green hydrogen production, carbon capture technologies, CO₂-based fuels for transport and aviation, CO₂-based building blocks, bulk and fine chemicals as well as advanced CCU technologies.

Carbon Capture and Utilisation (CCU) is one essential pillar for the supply of renewable carbon besides biomass utilisation and recycling. The transition to the direct use of CO₂ as one alternative carbon source is needed as a key element to substitute fossil sources, to fight climate change and to shift towards sustainable and climate-friendly production and consumption. For providing the full benefits of CCU technologies the use of renewable energy is indispensable.

Especially the supply of green hydrogen is crucial for the production of CO2-based fuels for transportation and aviation as well as for bulk and fine chemicals.

The “Conference on CO₂-based Fuels and Chemicals 2022”, 23–24 March 2022, Cologne, Germany. As a hybrid conference it combines a “live” in-person event with a “virtual” online component, www.co2-chemistry.eu.

Composites Evolution Ltd has teamed up with leading natural fibre reinforcement specialists Bcomp to launch a new range of flax-epoxy prepreg materials, designed to offer enhanced sustainability without compromising on performance.

Evopreg ampliTex™ prepregs combine Composites Evolution’s high-performance Evopreg epoxy resin systems with Bcomp’s award-winning ampliTex™ flax reinforcements, to deliver a family of materials which offer outstanding performance for component applications.

To reach the full performance of natural fibres, Evopreg ampliTex™ prepregs have been tailored to be compatible with Bcomp’s powerRibs™ reinforcement grid, enabling the same stiffness and weight as thin-walled monolithic carbon fibre parts while decreasing the CO₂ footprint by 85% and improving safety thanks to a blunt braking behaviour without dangerous debris or sharp edges.

Composites Evolution’s Sales & Marketing Director, Ben Hargreaves, explains further.
“Sustainability is an increasingly important factor for many of our customers - particularly those involved in motorsports and high-performance automotive applications. As you’d expect in these sectors though, sustainability can’t come at the expense of performance the two must go hand-in-hand. This is something that other prepreggers can struggle with, as natural fibres behave very differently to carbon or glass, for example.”

Customers would be able to understand the strengths and weaknesses of natural fibre composites, and to show where and how they can be adopted without the need for significant changes to existing composite component production processes.

One such customer is Retrac Group, whose composites division is one of the UK’s most experienced composites engineering companies across motorsports, automotive and aerospace. It recently used Evopreg ampliTex™ + powerRibs™ to produce a demonstrator bonnet panel for a race-bred supercar. Project Manager Alan Purves explains.

“We’re seeing a growing interest in flax fibre composites, particularly in the motorsports and niche vehicle sectors. It is therefore essential that we have developed an in-depth understanding of the processing requirements and performance capabilities of these materials, and are ready to respond to our customers' requirements. Being able to tap into the combined expertise and experience of both Composites Evolution and Bcomp is proving invaluable.”
