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.

Indorama Ventures Public Company Limited (IVL) named the winners of ‘RECO Young Designer Competition’, Thailand's largest upcycling fashion design event, parading haute couture garments containing at least 60% recycled materials.

Eleven finalists showcased 33 handmade sustainable outfits at the 9th edition of the fashion show at IVL’s headquarters in Bangkok, using recycled PET and polyester items to craft creative fashions. Under the concept of ‘REVIVE: Start from the Street,’ RECO supports young Thai designers while raising awareness of recycling. The designs use a range of recycled materials including recycled PET yarns, discarded fabric from factories, and even repurposed safety belts.

RECO awarded finalists and winners with 500,000 baht in prizes to support their careers. First prize of 125,000 baht was awarded to 23-year-old emerging furniture designer Prem Buachum for his ‘The Origin of Rebirth’ collection, using fabric recycled from post-consumer PET bottles. The first runner-up, Sathitkhun Boonmee, was awarded 75,000 baht for his ‘Remembering Your Favorite Teddy Bear’ collection, using old dolls made of polyester fibers. Second runners-up, Worameth Monthanom and Tanakorn Sritong, received 50,000 baht for their ‘Regeneration of Nature (into Spring)’ collection, using unused fabrics and discarded PET film. Napat Tansuwan, a finalist with his’ Don’t Judge’ collection, will go on to create designer merchandise for sponsor Buriram United Football Club using local weaving techniques from communities in Buriram province.

Mrs. Aradhana Lohia Sharma, Vice President at Indorama Ventures and RECO Young Designer Competition Chairperson, said, “Since 2011, RECO's ambition has been to uplift recycling and inspire people to realize the value of recyclable materials to produce great new products for daily life. We have witnessed many thoughtful initiatives on upcycling through the collections created by our talented young Thai designers. The designs this year showcase stunning wearability and innovation while using a large percentage of recycle materials. Public interest in recycling has been growing immensely, and we are grateful to strengthen the relationship with partners like Buriram United Football Club.”

“Indorama Ventures hopes this competition will be a driving force in nurturing sustainable fashion concepts and increasing the acceptance of recycled materials, especially post-consumer PET. We are proud to be a stepping-stone for our youth's design journey and our community’s sustainable future.”

Sicomin has confirmed that eco-surfboard specialist NOTOX will use GreenPoxy 56 in its latest line of R-CARBON boards. The new NOTOX R-CARBON boards are the first to use 100% upcycled carbon fibre fabrics recovered from a production waste stream at Airbus.

NOTOX, founded in 2006 and based in Basque, France, has partnered with Sicomin to use GreenPoxy bio-resins in several earlier flax, cork, and bamboo reinforced boards. In a quest to now produce the most sustainable carbon fibre reinforced boards possible, NOTOX has signed a formal agreement with Airbus Nantes to purchase defective carbon fabrics that were destined for landfill.

The new NOTOX technology gives a second life to Airbus carbon fabrics that are declared unusable for aerospace applications due to short roll lengths, an inability to be pre-formed, or other defects. The upcycled materials are combined with Sicomin GreenPoxy 56 and Surf Clear hardener, producing an extremely clear, high gloss laminate with high mechanical properties. NOTOX use a precisely controlled wet lamination process with vacuum bag consolidation to wet out the upcycled woven carbon fabrics and minimise resin consumption in the manufacturing process.

In addition to selecting a high bio-content resin – GreenPoxy 56 derives 56% of its carbon content from plant sources – NOTOX has also sourced the most sustainable carbon fibre fabrics. Full life cycle analysis by NOTOX has shown that using waste carbon fabrics from Airbus is significantly more energy efficient than using other recycled short fibre carbon, confirming the importance of upcycling this key raw material.
