The recycling of end-of-life vehicles (ELVs) is a cornerstone of Europe\u2019s circular economy ambitions. While metals such as steel and aluminium are long-established in recycling systems, complex materials like polymers, composites, and multi-material assemblies have made the recovery of vehicle components significantly more challenging. To secure valuable resources and reduce environmental impacts, automotive recycling must evolve to address these materials with precision, efficiency, innovative technology and scientific rigour. Taking place on 19-20 November 2025, the Advanced Recycling Conference 2025, hosted by nova-Institute, will spotlight innovative technologies and solutions int this sector by providing a vital forum for collaboration between science and industry<\/strong>.<\/p>\n\n\n\n

Policy Landscape and the Urgency for Action in the Automotive Sector<\/h3>\n\n\n\n

The European Union\u2019s Directive 2000\/53\/EC on End-of-Life Vehicles laid the foundation for vehicle recycling more than two decades ago. However, with the European Green Deal and Circular Economy Action Plan pushing for improved material circularity, a new regulatory framework is emerging. The proposed End of Life Vehicles Regulation (COM (2023) 451) will extend obligations across the full vehicle lifecycle, including a requirement for a minimum of 25 % recycled plastic content  from EOL vehicles in new vehicles and mandatory design provisions for the removability of large mono-plastic parts (European Commission, 2025).<\/p>\n\n\n\n

In March 2025, the Council of the European Union endorsed these measures, underlining that future vehicles must be designed for dismantling, reuse, and high-value recycling (Council of the EU, 2025). Industry associations have responded: EuRIC (2024) supports life-cycle-based implementation, while the European Composites Industry Association (EuCIA, 2023) stresses the need for proportionate targets that reflect composite material realities.<\/p>\n\n\n\n

Complexity in Automotive Materials<\/h3>\n\n\n\n

This evolving policy context is reshaping the automotive recycling sector. What was once a linear end-of-pipe activity is now a design and materials-management challenge across the entire vehicle value chain.<\/p>\n\n\n\n

Plastics and Polymers<\/strong><\/h3>\n\n\n\n

Plastics account for nearly 20% of a modern car\u2019s mass, mainly including PP, PE, PA, ABS and blends. Mechanical recycling remains limited by paints and additives, but solvent-based and other chemical recycling routes show promise for the recovery of high-quality products (Zambrano et al., 2024; Ravina et al., 2023).<\/p>\n\n\n\n

Fibre-Reinforced Composites<\/strong><\/h3>\n\n\n\n

Glass- and carbon-fibre reinforced polymers provide lightweight strength but resist conventional recycling. Pyrolysis and solvolysis can recover fibres, yet, cost and quality losses remain barriers (Khan et al., 2021; Mbatha et al., 2024).<\/p>\n\n\n\n

Lightweight Alloys<\/strong><\/h3>\n\n\n\n

Aluminium use is expanding, yet alloy mixing leads to downcycling. Sorting advances such as spectroscopy-based classification can support a closed-loop recovery (Shankar et al., 2024; Tiwari et al., 2025).<\/p>\n\n\n\n

From Dismantling to Digital Traceability<\/h3>\n\n\n\n

Modern vehicles combine bonded composites, embedded electronics, and mixed joints that complicate disassembly. The proposed ELV regulation introduces design-for-disassembly obligations, requiring non-destructive removal of large polymer parts before shredding Research into \u201cactive disassembly\u201d using smart fastening materials could further improve component recovery.<\/p>\n\n\n\n

A promising pathway is improved sorting and advanced separation. After shredding, the automotive shredder residue (ASR), a mixture of plastics, foams, glass, textiles, and metals,  remains a key bottleneck. Advanced sorting technologies using near-infrared or hyperspectral sensors can separate valuable polymer fractions for reuse or chemical recycling.<\/p>\n\n\n\n
