From the Sector

Carbon fiber-reinforced polymer lamellas are an innovative method of reinforcing buildings. There are still many unanswered questions regarding their recycling, however. A research project by Empa's Mechanical Systems Engineering lab is now set to provide answers. Thanks to the support from a foundation, the project could now be launched.

The construction sector is responsible for around 60 percent of Switzerland's annual waste. The industry's efforts to recycle demolition materials are steadily increasing. Nevertheless, there are still end-of-life materials that, for the time being, cannot be reused as recycling would be too time-consuming and expensive. One of these are carbon fiber-reinforced polymer (CFRP) lamellas.

Making buildings "live" longer
The reinforcing method developed by Urs Meier, former Empa Director at Dübendorf, has been used in infrastructure construction for 30 years. CFRP lamellas are attached with epoxy adhesive to bridges, parking garages, building walls and ceilings made of concrete or masonry. As a result, the structures can be used for 20 to 30 years longer. The method is increasingly being applied worldwide – mainly because it massively improves the earthquake resistance of masonry buildings.

"By significantly extending the lifespan of buildings and infrastructure, CFRP lamellas make an important contribution to increasing sustainability in the construction sector. However, we need to find a way how we can further use CFRP lamellas after the buildings are being demolished," explains Giovanni Terrasi, Head of the Mechanical Systems Engineering lab at Empa. To achieve this, he wants to develop a method for recycling CFRP lamellas. Convinced by this idea, a foundation supported it with a generous donation. The project officially launched in October.

Gentle separation
First, a mechanical process will be developed to detach the CFRP lamellas from the concrete without damaging them. Initial tests at Empa are encouraging: After the lamellas were separated from the concrete, they still had a strength of 95 percent – even if they had already been used for 30 years.

Then, the demolished CFRP lamellas shall be used to produce reinforcement for prefabricated components. Terrasi's goal: saving thousands of tons of CFRP lamellas from ending up in landfills after the demolition of old concrete structures and reuse them in low-CO₂ concrete elements. After completion of the project, Giovanni Terrasi and his team – consisting of Zafeirios Triantafyllidis, Valentin Ott, Mateusz Wyrzykowski and Daniel Völki – want to produce railroad sleepers from recycled concrete, which will be reinforced and prestressed with demolition CFRP lamellas. This would give the "waste-to-be" material a second life in Swiss infrastructure construction.

The adoption of composite parts based on flax fibres by the Marine Industry continues to grow, with major OEMs as well as smaller shipyards now aiming to take advantage of the reduced carbon impact and impressive mechanical properties they can provide.

“Over the last ten or fifteen years, several innovative flax fibre boats have been built and the fibre has started to gain significant traction,” says Julie Pariset, Innovation & CSR Director at the Alliance for European Flax-Linen and Hemp. “In addition to the environmental benefits, manufacturers are realising significant technical and processing gains with flax fibre composites.”

“Flax is a very low-density fibre, with a high specific stiffness,” she explains. “It can be used to manufacture composite laminates with mechanical properties not dissimilar to typical E-glass composites and the coefficient of thermal expansion of a flax fibre epoxy part is also quite close to that of a carbon fibre part.” This allows the materials to work well in combined assemblies with carbon fibre composites and the flax parts are also highly impact resistant.

Flax fibres also provide acoustic and vibration damping in composite applications, as well as providing a warm and aesthetically pleasing appearance below decks.

ecoRacer30
As a member of the Alliance for European Flax-Linen and Hemp, Bcomp, headquartered in Fribourg, Switzerland, has this year been working with Northern Light Composites (nlcomp), based in Monfalcone, northern Italy, on the creation of what is billed as the first fully recyclable nine-metre-long sailing boat – the ecoRacer30.

The boat is based on nlcomp’s proprietary rComposite technology – a combination of thermoplastic resins and BComp’s ampliTex high-performance natural fibre reinforcement fabrics and patented powerRibs technology.

It was built in a collaborative effort with the help of Barcelona-based Magnani Yachts, which took care of the composite manufacturing, and Sangiorgio Marine, which provided technical assistance as the boat was being assembled at its shipyard in Genova, Italy.

Magnani Yachts has subsequently become the first shipyard to hold an rComposite license and others are now being encouraged to adopt the technology.

The second ecoracer30 is currently under construction and has already been sold and nlcomp is planning to build a fleet of eight of these boats in time to enter a series of regattas in the summer of 2025.

Flax 27 Daysailer
Greenboats, based in Bremen, Germany, is another specialist in building boats from natural fibre composites and has this year launched the Flax 27 daysailer.

The lower hull of this vessel is also made from Bcomp’s ampliTex technical fabrics in combination with a sandwich core of recycled PET bottles. Using a vacuum infusion process, the fibres were integrated with a plant-based epoxy resin in order to further reduce the CO₂ footprint of the vessel.

The light structure and modern shapes of the lower hull of the boat result in very fast, sharp and agile handling on the water.

Greenboats has also recently announced significant new backing from alliance member Groupe Depestele, which manages 13,000 hectares of flax land in Normandy, France.

Blue Nomad
A project in Switzerland has meanwhile proposed the use of flax fibre composites in solar-powered habitats designed for comfortable living on the oceans – as the world grapples with the frightening implications of climate change and rising sea levels.

As envisaged by students from Institut auf dem Rosenberg in St Gallen, Switzerland working with Denmark-based SAGA Space Architects, Blue Nomad structures would form modular blocks to establish large communities and oceanic farms.
 

MAS Holdings, a global apparel & textile manufacturing and tech conglomerate, headquartered in Sri Lanka, secures a stake in HeiQ AeoniQ™ as part of its Plan for Change initiative to support the development of next-generation cellulosic filament fibers to replace polyester and nylon.

HeiQ from Switzerland and MAS Holdings entered a partnership for MAS to secure a stake in HeiQ AeoniQ GmbH, a subsidiary of HeiQ Group that will produce HeiQ AeoniQ™, a climate-positive cellulosic yarn.

With this investment, MAS Holdings becomes the first manufacturer to partner with HeiQ AeoniQ™ in their efforts to provide a sustainable alternative to polyester and nylon. The investment to be made by MAS Holdings is part of the group’s strategy to drive a positive environmental impact. The MAS Plan for Change aims to generate 50% of the company’s revenue through sustainable products by 2025, revolutionizing the textile industry with a focus on innovation, sustainable sourcing, and pioneering circularity at scale.

With the closing of this deal, HeiQ and MAS agreed to a 5-year Offtake Agreement for 3,000 tons of HeiQ AeoniQ™ yarn in 2025 and 5,000 tons per year from 2026 to 2029, valued by HeiQ in the aggregate to US$ 100 million. MAS will finalize this commitment within a stipulated time period after achieving milestone 1, and a mutual plan for commercialization. HeiQ and MAS firmly believe that rapid scaling is key to facilitating the fast adoption of sustainable, circular technologies such as HeiQ AeoniQ™.

The HeiQ AeoniQ™ pilot plant in Austria is manufacturing this revolutionary continuous cellulosic filament yarn since Q3 2022, with up to a 100 tons capacity to be upscaled up to 300 tons by the end of 2023.

The HeiQ AeoniQ™ production scale-up is planned to have its definitive boost by early 2026 with the construction of an entirely new gigafactory capable of a 30,000-ton output per year, in a 250M USD estimated investment.

Polyester and nylon, two oil-based fibers, virtually non-recyclable, account for about 70% of all the global textile production, they take between 350 to 1000 years to degrade in nature, are currently close loop recycled at less than 1%, and are at the origin of 35% of the microplastics that can be found in today's oceans. HeiQ AeoniQ™ was innovated and is being hyper-scaled up to change this course of action.

Haelixa, the Swiss traceability company and Damteks Textiles have announced a collaboration to mark and trace recycled acrylic fiber. Damteks is offering their recycled yarn to customers whereby they are able to place an order with the unique Haelixa DNA already attached.

The Haelixa solution is DNA markers which are solved in liquid and applied to fibers as a fine spray. Spot checks are completed after spraying to determine the presence of DNA and identify the product. The test is based on PCR technology that is 100% reliable and has forensic validity.

Damteks saw an increase in demand for blended yarn in the last year. The request is most often a composition of 30% recycled fiber with 70% standard fiber. Brands are looking for options to be more sustainable and Damteks proactively sought out an answer. They are offering the yarn with Haelixa DNA to validate the recycled acrylic in the mix.

The haelixa team visited the Damteks recycling facility in Istanbul to kick off the partnership that will continue throughout 2023. The traceability program has the DNA sprayed on the recycled fibers before spinning. The project also saw the use of a tailored Haelixa liquid sprayer designed by the team based in Switzerland. When manufacturers do not have built-in moisturizing systems, Haelixa provides them with a custom unit to shower the DNA liquid onto the fibers. This sprayer is engineered to match the mechanical processing of the customer.

Damteks is a family-owned business that pride itself in carefully selecting environmentally responsible options for its production processes. On top of the certifications they have obtained including - GRS, RCS, GOTS, OCS - Damteks decided to have their products "Marked and Traced by Haelixa" to add additional credibility and reliability. Damteks plans to offer marked and traced by Haelixa yarn in different dyes as their offering to brands.

• Polynova to gain market share for the GRAFE Group in the Swiss region from November The GRAFE Group, Blankenhain, has found a new sales representative for Switzerland in Polynova Group AG, Risch-Rotkreuz (Switzerland).

The partnership will be officially launched at Fakuma 2021. "Our new Swiss agency specialises in the distribution and production of high-quality technical plastic granulates and has been active on the market for more than 20 years. The company has a large customer base and the necessary technical expertise to advance our goals in this important market. This includes raising our profile, educating people about our product range and ultimately gaining market share," says Stefanie Theuerkauf, Sales Manager for the D-A-CH region. Polynova employs five sales staff and three in logistics, all of whom have a technical background. The company's own warehouse in Rothenburg also ensures the availability of the plastics.

"GRAFE fits perfectly into our product portfolio," says Thomas Weigl, co-owner and responsible for business development at the Swiss distribution company, whose employees recently underwent intensive training in Blankenhain. "Our customers come from the sports goods, housing technology, automotive supplier and medical technology sectors - there are many synergies with GRAFE." Weigl himself has extensive experience in the masterbatch sector and has worked for two companies in the industry - Sukano and Americhem - as managing director. "Swiss companies want Swiss contact persons. We speak the languages German, Italian and French, are on site in the shortest possible time, offer direct contact and understand the needs of the customers and the requirements of the market," he explains. "Polynova is thus faster, closer and more direct." "The Swiss market is large and important for us," reports Theuerkauf and Weigl explains the background: "There are over 300 plastics processors, many are family-run and very technically oriented. The origins of the companies are often in the watch industry and in the production of the smallest precision parts such as gear wheels. In addition, coffee machine manufacturers, medical technology providers and automotive suppliers are important market players. A large number of well-known OEMs are located here."

Even though there are already masterbatch manufacturers in the Alpine country, says the sales expert, no one has the know-how to adjust compounds and masterbatches as perfectly and precisely as the company from Thuringia. In addition to a complete range of colours on practically all plastic substrates, flame retardants, UV additives, thermal stabilisers or lubricants are further examples of the extensive product portfolio. GRAFE is one of the specialists in the modification of thermoplastics and is an innovation driver in the production of colour masterbatches. "The technical possibilities in terms of a state-of-the-art technical centre and production machinery, as well as one of the largest research and development departments in the industry, are also not to be found elsewhere on the Swiss market. Our task now is to bring these to the attention of domestic customers," says Thomas Weigl, co-owner of Polynova AG together with founder Renato R. Huebscher.

The UK’s Fibre Extrusion Technology (FET) will introduce its new lab-scale spunbond system at the forthcoming INDEX 2020 nonwovens exhibition taking place in Geneva, Switzerland, from October 19-22.

The new spunbond range provides unprecedented opportunities for the scaled development of new nonwoven fabrics based on a wide range of fibres and polymers, including bicomponents.

FET has already supplied one of these new spunbond lines to University of Leeds in the UK, and a second, in combination with a metlblown line, to the University of Erlangen-Nuremberg in Germany.

“Our new spunbond technology is unique in providing the ability to process a wide range of polymers, including those normally not considered appropriate for the spunbond process, at the scale required to fully explore material combinations and bring new products to market,” says FET Managing Director Richard Slack. “FET has built on its melt spinning expertise to develop a true laboratory scale spunbond system.”

The Discover Natural Fibres Initiative (DNFI) will announce the winner of the Innovation in Natural Fibre Research Award soon. The aim of the award is to raise awareness of the achievements of the natural fibers sector by recognizing innovative and progressive work by people and institutions at the level of production and use of natural fibers. The closing date for applications was September 10.

Interest in the award was high again in 2021, indicating that research in fields involving natural fibres is robust. The applications that were received reveal a fascinating array of projects, new topics, and both private and public sector funding for natural fibre research.

There are seven finalists, and final judging is underway. The winner of the 2021 Award will be announced in early October.

The seven finalists for the 2021 Award fall into several broad categories, including traceability and the measurement of environmental impacts of natural fibres, the use of natural fibres in manufacturing biodegradable composites, and new or expanded uses for natural fibre materials. Researchers and institutions located in Australia, India, Republic of Korea, and Switzerland are among the finalists for the 2021 award.
