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.

INDA, the Association of the Nonwoven Fabrics Industry, announced the three finalists for the World of Wipes Innovation Award®. The Award will be presented at the annual World of Wipes® (WOW) International Conference, June 17-20, at the Hyatt Regency Minneapolis in Minneapolis, Minnesota.

The three products vying for this Award are multi-purpose cleaning wipes from Kimberly-Clark Professional, a bio-binder technology from OrganoClick, and facial care wipes from Rockline Industries. The winner will be announced on Thursday morning, June 20th.

The three companies competing for the Award are:

• Scott® Xtreme Multi-Purpose Cleaning Wipes by Kimberly-Clark Professional:
  Scott® Xtreme Multi-Purpose Cleaning Wipes are great for tackling extreme cleaning tasks, like removing oil, grease, grime, paint, adhesives, caulk, and more, yet are gentle enough to clean hands.  Featuring a patented citrus cleaning solution, the dual-action cleaning fabric incorporates a textured side to increase scrubbing action for cleaning tough soils and a smooth side for wiping surfaces clean.  Scott® Xtreme Multi-Purpose Cleaning Wipes are truly a must-have for any DIY job and cleaning on-the-go.
• OC-Biobinder® Lily1450 by OrganoClick:
  OC-Biobinder® represents a series of bio-based and biodegradable binders intended for the nonwoven and paper industry. They are produced from renewable raw materials and residual streams from the food industry and replace traditional fossil-based plastic binders. OC-Biobinder® is available with many different properties adapted to the production of home compostable nonwoven materials such as premium napkins, table cloths and wet wipes.
• Facial Care Wipe with Glycine Amino Acid Complex by Rockline Industries:
  Rockline’s development of a facial wipe product containing a unique multifunctional complex of two glycines, a phospholipid compound and a blend of glycols allows for a multitude of skincare benefits as well as providing a self-preserving system for cellulosic nonwovens. Believed to be the first application of glycines in a wet wipe formulation, the product offers improved skin smoothness, elasticity, and hydration alongside an anti-aging claim.

INDA’s Technical Advisory Board selected the finalists based on the creativity, uniqueness, and technical sophistication employed in finding novel ways to expand the utilization of nonwovens. Categories considered for the award were wipes-related raw materials, roll goods, converting, packaging, active ingredients, binders, additives, and end-use products.

The 2023 World of Wipes Innovation Award winner was Indorama Ventures and Polymateria for their Nonwoven Wipe Using Biotransformation Technology. This innovative spunlace wipe utilized advanced biotransformation technology developed jointly by Indorama Ventures and Polymateria. Meeting the BSI PAS 9017 specification, this wipe in the event it becomes fugitive, and exposed to heat, sunlight, air and moisture will transform into a harmless, bioavailable wax at its end-of-life, eliminating microplastic pollution. Compatible with mechanical recycling and combatting 'fugitive' waste, this wipe represents a significant leap towards eco-friendly, sustainable nonwoven hygiene products.

British technology company Hypetex has been awarded a significant grant from Innovate UK to develop the world’s first technical coloured flax fibre, which will have applications in the sustainable manufacturing of cars, boats and other products that are usually made with carbon fibre.

Called FlaxTex the material is strong, lightweight and 100 per cent biodegradable, having a net positive carbon footprint at point of manufacturing. It can be colourised whilst enhancing its performance properties, with the process adding some important manufacturing attributes compared to standard flax fibre.

As such, FlaxTex’s mechanical properties represent the closest sustainable substitute for robust and lightweight materials like glass fibre and carbon fibre in composite structures.  

The performance of standard flax fibre is often hindered by its high moisture absorption, resulting in reduced structural integrity when used in composite construction. In addition, the natural brown colour of flax has been deemed unappealing for product use.

Flaxtex solves these issues by removing moisture through the colouring process and sealing the fibres, which waterproofs them and enabling their core mechanical properties. Hypetex’s patented nano-pigment technology changes the colour adding an aesthetic quality to the material.  

This colouring process is set to transform industrial design possibilities of Flax natural fibres by enhancing the strength and performance while simultaneously reducing post-processing requirements and total energy usage. This also aligns with Hypetex's commitment to supporting the green transition and helping manufacturers meet government expectations on the path to UK Net Zero targets and the European Green Deal.

Over the course of a 12-month industrial research project, Hypetex will further optimize its resin systems and processes, expanding the use of FlaxTex across various markets.  

FlaxTex has a range of industry uses, including on construction, automotive, sports equipment and furniture products.
