“The co-operation with RE Plano is an important step in the upcycling of PCR from the lightweight packaging fraction for technical applications, such as vehicle interiors,” said Dirk Breitbach, managing director of TechnoCompound. “This application has very high requirements in terms of emissions and odours, as well as the mechanical properties of our products.” At its sorting plant in Bochum, Germany, RE Plano uses an AI-supported system that recognises individual packaging, enabling the company to achieve the highest purity levels in the recycled material it produces. Through compounding, additivation and further material processing, TechnoCompound uses these raw materials to produce plastic grades that pass emission cham- ber tests specified by vehicle OEMs.

Interior benefit Simoldes has also worked with Elix Polymers to incorporate more recycled materials into premium vehicle interiors. In its Boost project, Simoldes aims to increase the use of renewable materials by 40% during the development phase of its products. This is where E-Loop products from Elix come in, as they have mechanically recycled content. A technical valida- tion process – on a PC/ABS with 30% PCR content – included mechanical, thermal, process- ability, odour and emission perfor- mance against the needs for automotive interior non-visible safety products. The product has shown equivalent properties compared to the traditional prime materials, but the carbon footprint can be reduced by up to a 40%. Demanding upper interior pillars with airbag have been injected in a “unique” process, with moulds from Simoldes, to produce textile-covered parts. Visible decorative parts for door panels with class A surfaces have also been part of the evaluation programme. The parts have been presented to automotive OEMs.
Technical boost TechnoCompound and RW Plano are working on concepts using post-consumer recyclate (PCR) in technical products in automotive applications. The project to use PCR packaging is performed against the backdrop of the numerous EU regula- tions that are currently being discussed and have already been passed, such as the End-of-Life Vehicles Directive.

Recycled PA12 CRP Technology has launched an injection-mould- ing grade of PA12 that has been recycled from a 3D-printing grade. Windform XT 2.0 IMG includes carbon fibres and is derived from the company’s Windform XT 2.0 selective laser sintering (SLS) grade. It does not incorporate any virgin materials, says the company. Windform XT 2.0 is supplied as a powder which, when no longer suitable for the SLS process, is collected and reprocessed into Windform XT 2.0 IMG pellets. “We have regranulated the Windform XT 2.0 powder cake, and made it suitable for injection moulding,” said Franco Cevolini, CEO and technical director at CRP. “We
are now ready to sell it to those who manufacture in large volumes.” Material properties include high
stiffness and shock resistance. This
makes it suitable for industries such as automotive, transport and industrial design.
