The IKV project &#8220;LFT Recycling&#8221; addresses the question of how large-volume LFT components can be recycled at the material level and how high-quality recyclates can be reused. To investigate the material recyclability of long-fibre-reinforced thermoplastics (LFT), a pilot-scale processing chain was implemented, comprising plastification, compression moulding, component production, mechanical shredding, and reprocessing. Substantial fibre damage and shortening already occur during both shredding and plastification. Screw speed proved to be a key parameter. Furthermore, it can be inferred that during shredding, suitable classification enables removal of fine, heavily damaged fractions from the cycle to enhance material quality.                    <\/div>\n                                            <\/div>\n        <\/div>\n    <\/section>\n\n\n<figure class=\" relative flex flex-col gap-2xs mb-xs md:mb-l xl:mb-xl\"><img decoding=\"async\"  class=\" w-full  \"  src=\"https:\/\/ikv-aachen.de\/wp-content\/uploads\/2026\/04\/22995N.jpg\" srcset=\"https:\/\/ikv-aachen.de\/wp-content\/uploads\/2026\/04\/22995N-748x499.jpg 748w, https:\/\/ikv-aachen.de\/wp-content\/uploads\/2026\/04\/22995N-1536x1024.jpg 1536w, https:\/\/ikv-aachen.de\/wp-content\/uploads\/2026\/04\/22995N-768x512.jpg 768w\" sizes=\"auto, (max-width: 1536px) 100vw, 1536px\" width=\"1536\" height=\"1024\" alt=\"22995N\" loading=\"lazy\" \/><span class=\" text-copyright order-3 justify-end text-right w-full  w-full \">&copy; IKV<\/span><figcaption class=\" w-full  text-figcaption justify-end text-right \">Fig. 1: Processing and recycling chain for LFT recyclate<\/figcaption><\/figure>\n\n\n<p class=\"wp-block-paragraph\">Alongside material properties, a life cycle assessment (LCA) evaluated the environmental impacts of different processing routes. For the scenarios studied with 25% recycled content, the comparison with conventional processing routes indicates potential reductions in the environmental impacts covered by the LCA (Fig. 1). A key factor in these results is the assumed material recycling at end of life instead of energy recovery. The project thus shows under which of the conditions investigated LFT recyclate could partially replace virgin material. Challenges remain in maintaining consistent material quality, ensuring process stability at high recycled contents and processing contaminated post-consumer material streams. The findings provide a basis for investigating these questions systematically in future projects, including fibre-length-preserving processing methods and the combination of recyclates with recycled unidirectional tapes.<\/p>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>Project data and funding<\/summary>\n<p class=\"wp-block-paragraph\">We would like to thank the BMWE for funding the IGF project (funding code 22995 N) and the project partners for their cooperation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Project duration: 01.11.2023 &#8211; 31.10.2025<\/p>\n\n\n<section id=\"logo-bar-block_152ea151fb0c30a4c2c9d4623aa2e2a3\" class=\"block-logo-bar py-2xl  clear-both\">\n    <div class=\"theGridWrapper overflow-hidden  \">\n        <div class=\"grid grid-cols-[repeat(auto-fill,minmax(140px,1fr))] gap-base\">\n                            <figure class=\" relative h-full  \"><img decoding=\"async\" fetchpriority=\"low\"  class=\" object-contain w-full h-full mb-base  \"  src=\"https:\/\/ikv-aachen.de\/wp-content\/uploads\/2024\/10\/BMWE-Logo.png\" srcset=\"https:\/\/ikv-aachen.de\/wp-content\/uploads\/2024\/10\/BMWE-Logo.png 500w, https:\/\/ikv-aachen.de\/wp-content\/uploads\/2024\/10\/BMWE-Logo-335x335.png 335w\" sizes=\"auto, (max-width: 748px) 100vw, 748px\" width=\"500\" height=\"500\" alt=\"BMWE-Logo\" loading=\"lazy\" \/><\/figure>                                <\/div>\n    <\/div>\n<\/section>\n<\/details>\n","protected":false},"excerpt":{"rendered":"<p>For long-fiber-reinforced thermoplastics (LFT), there are currently no established recycling routes to maintain the fiber length during recycling.
