From the Sector

Breaking new ground in plastics recycling means assessing the value chain from end to end. The big opportunities for the future are in fine-tuning the individual process steps; from the collection of recyclable materials to the recycling process and the end product. This is where the cooperation of Lindner and the EREMA Group comes in, officially launched following the 50/50 founding of the holding BLUEONE Solutions in August 2023 to which shares of Lindner Washtech were contributed. The expertise of EREMA, a manufacturer of extruders and filtration solutions for plastics recycling and the largest company within the EREMA Group, has now been combined with the expert know-how from Lindner Washtech, a leading provider of all-in-one solutions for shredding, sorting and washing plastic feed materials.

Data transfer ensures more efficient recycling processes
Process control is an especially important aspect of plastics recycling, which is why standardising the process control system was what the two companies focused on first. "Together, we have developed a platform that allows data to be exchanged between the extruder and the washing system," says Manfred Hackl, CEO of the EREMA Group at IFAT in Munich. "This enables us to analyse the data more precisely so that effective improvement measures can be deduced." All key parameters are taken into account and monitored via a digital interface. For example, it is possible to use information relating to the current throughput of the EREMA Pre Conditioning Unit to optimise the washing process as soon as possible so that it can compensate for fluctuations in capacity and achieve a significant increase in output. This data transfer represents a new step on the roadmap to digitalization.

High efficiency due to smart energy management
"To ensure sustainable recycling, it is necessary to find the right process for each application and to make sure that the individual process steps are perfectly coordinated," emphasizes Michael Lackner, Managing Director of Lindner. Coordinating the process steps has already achieved initial success in energy management, and a clear example of this is heat recovery. "We use the latent heat generated during the extrusion process as an energy source for the washing and drying process," explains Lackner. "This enables our customers to sustainably reduce their energy costs and carbon emissions".

Making the most of synergies along the value chain
Synergies need to be used to establish the quality standards specified for each end application. "The key question is how we can improve the end product and increase the overall efficiency of the recycling process at the same time," agree Manfred Hackl and Michael Lackner. This will only work if companies work together along the value chain. The industry leaders can already point to several examples where together they have improved recycling processes and made it possible to move away from downcycling. "An example of this is the recycling loop of HDPE starting material, which is processed into high-quality, food-safe rHDPE pellets using our two technologies," says Lackner. Lindner Washtech and EREMA continue to work intensively together to develop strategies for upcycling plastics and increase recycling rates.

Solvay is partnering with transportation providers KIITOSIMEON and ADAMS LOGISTICS to reduce the carbon footprint of its facility in Voikkaa, Finland. Known for its hydrogen peroxide technology, the site has a yearly capacity of 85 kilotons, making it the largest hydrogen peroxide unit in the country and one of the largest in Europe. However, the transportation of its products results in more than 850 tons of CO2 emissions annually, attributed to the several thousands deliveries conducted each year.

While the Voikkaa site has been operating on 100% wind-generated electricity since 2023, the journey towards decarbonization takes another step forward as it transitions transportation fuel from diesel to biofuel in the first quarter of 2024. This shift will result in a significant annual reduction of over 700 tons of CO2 emissions, representing more than 8O% reduction in the site's transportation carbon footprint.

As part of its commitment to carbon neutrality by 2050, Solvay has outlined a sustainability roadmap with around 40 energy transition projects. These projects focus on eliminating coal usage, emphasizing renewable energy sources, prioritizing energy efficiency, and driving process innovation. Solvay has further committed to reduce its emissions* along the value chain by 20% by 2030.

*scope 3 emissions, focus 5 categories, 2021 baseline

CARBIOS, a pioneer in the development and industrialization of biological technologies to reinvent the life cycle of plastic and textiles, has received an initial payment of €1.2 million from the French Agency for Ecological Transition (ADEME) for the OPTI-ZYME research project, carried out in partnership with INRAE2, INSA3 and CNRS4 via the TWB5 joint service and TBI6 research units, a project co-funded by the French State as part of France 2030 operated by ADEME. With CARBIOS' aim to optimize and continuously improve its unique enzymatic PET depolymerization technology, the 4-year7 OPTI-ZYME project aims to investigate the scientific and technical levers for improving the competitiveness of the process, optimizing the necessary investments and reducing its environmental footprint.

This collaborative R&D program focuses on the technical and economic optimization of process stages, while preserving the quality of the monomers obtained. These optimizations, new developments and the exploration of innovative solutions should enhance the technology's flexibility with regards to incoming waste. Raw materials could come from different sources that are currently rarely or not recycled, notably food trays and textiles, or a mix of incoming materials. It also aims to limit input and water consumption, as well as regenerate or reduce co-products and ultimate residual waste. Finally, it seeks to support enzyme optimization to maximize the process’ economic profitability and competitiveness.

The project therefore aims to achieve an overall improvement in performance, combining efficiency, quality and environmental sustainability, to benefit the Longlaville plant which is currently under construction, and future licensed plants.

In May 2023, CARBIOS, the project leader and coordinator, announced that it had been awarded a total of €11.4M in funding by the French State as part of France 2030, operated by ADEME, including €8.2M directly for CARBIOS (€3.2M in grants and €5M in repayable advances) and €3.2M for its academic partners INRAE, INSA and CNRS (via the TWB mixed service and TBI research units). This funding, which is made up of grants and repayable advances, will be paid out in several instalments over the course of the project, including an initial instalment of 15%, equivalent to €1.2 million, received by CARBIOS on 5 December 2023. The first Monitoring Committee with ADEME for the first key stage of the project will be held in February 2024 to validate the granting of the second instalment of funding.

This project 2282D0513-A is funded by the French State as part of France 2030 operated by ADEME.

To meet future demands on the amount of textile waste which needs to be collected and sorted, as well as the demand on recycling feedstock, it is necessary to match the demand and need for sorting of waste in Europe and create cost efficiency sorting capacities with larger scale and automation are necessary.

In an online session “Redefining Textile Waste Sorting: Impulses and findings for the future of next-gen sorting facilities” Texaid and partners talk about the current state of development and the challenges for the future.  Anna Pehrsson (Texaid), Gesine Köppe (ITA Augsburg GmbH) and partners present the results of a Technology Assessment conducted within The Transform Textile Waste into Feedstock Project (initiated by TEXAID within the ReHubs initiative) to assess the best available sorting techniques and process.

The innovative company RUDOLF has been honoured for its outstanding achievements in the field of sustainability and environmental protection and has won the coveted Responsible Care Federal Competition 2023 in the category SME.

The award was presented as part of a competition organised by the German Chemical Industry Association (VCI). Responsible Care is a voluntary initiative of the chemical industry. Its aim is continuous improvement in the areas of environmental protection, health and safety. Chemical companies and associations in more than 50 countries support the initiative. The award-winning project of the innovative company RUDOLF impressed the jury with its pioneering technology, which reduces CO2 emissions by up to 99.9 % compared to conventional cooling systems. „The project uses near-surface geothermal energy for industrial cooling - according to the motto „Efficiency First“ the most efficient way has been chosen!“ - Jury statement
 
TerraCool‘s winning system uses near-surface geothermal energy as the most natural form of cooling. It utilises the constant temperature of around 10°C at a depth of around 10 metres below ground. A specially developed heat exchanger system takes advantage of this natural cooling effect. In the future, it will be used to cool chemical production processes at RUDOLF. The main advantage of this technology is that it is CO₂ neutral. The technology is highly efficient and consumes only 0.1 % of the electricity used by conventional cooling systems.  By using natural resources, the system reduces CO₂ emissions by up to 99.9 % compared to conventional cooling systems, resulting in a very presentable carbon footprint. Another impressive aspect is its high energy efficiency. With just 1 kW of electrical energy, the system generates up to 600 kW of cooling capacity, thanks to the use of a highly energyefficient circulating pump system. Energy is, and will continue to be, a valuable „raw material“ for our industry and one that we need to manage carefully. The system is self-contained and has no contact with groundwater. No environmentally harmful refrigerants or antifreeze are required. With this technology, RUDOLF has made a pioneering contribution to the climate-neutral transformation of the economy, proving that innovative solutions can go hand in hand with environmental protection and sustainability. The Responsible Care award recognises the company‘s commitment to a greener future.

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.

Silence and resource efficiency are the order of the day in the development and optimization of electric vehicles. On the one hand, ever stricter emissions regulations worldwide are increasing demand for components that reduce noise pollution while helping vehicle manufacturers meet their sustainability targets. On the other hand, the absence of noise from the combustion engine in e-cars amplifies the disruptive effects of other noise sources in the passenger compartment. With Ultra-
Silent Tune, Autoneum now presents a new lightweight and environmentally friendly technology for underbody shields that reduces tire rolling noise both outside and inside the vehicle, thus improving not only acoustic performance but also driver comfort in electric cars.

Autoneum's Ultra-Silent Tune technology owes its sound-absorbing performance to acoustic chambers of different shapes and sizes. The chambers are created by applying an embossed polyester foil to the side of the Ultra-Silent underbody shield facing away from the noise source: they capture the sound waves emitted by the car tires, modulate them according to their respective geometry and reflect them back onto the porous carrier material. Compared to conventional single-layer underbody shields, whose acoustic performance is mainly determined by the noise-reducing properties of the product side facing the tires, Ultra-Silent Tune exploits both sides of the component, which significantly improves its acoustic absorption. Autoneum thus makes innovative use of the proven concept of traditional chamber absorbers, reducing exterior tire rolling noise.

Moreover, Ultra-Silent Tune combines optimized acoustic performance with the sustainability benefits of Autoneum's Pure technology Ultra-Silent. In addition to the high proportion of recycled PET fibers, underbody shields made from Ultra-Silent Tune can be manufactured from 100% polyester and thus be fully recycled at the end of vehicle life. Furthermore, the thickness of the multilayer construction can be flexibly adapted to the packaging spaces of different vehicle models. Underbody shields made from Autoneum's new Ultra-Silent Tune technology are already in pre-development at various vehicle manufacturers in Europe.

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.

• 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.”
