Extending the lifecycle of ELV - trends and regulations
Recycling vehicles is anything but a walk in the park. Vehicles are made of multiple materials, from plastic, aluminum, glass, rubber, steel, and many more precious metals – vehicles have it all. While all these materials are indispensable for the manufacture of safe and convenient cars, they add complexity to the dismantling and recycling process as these materials require different methods of separation and processing.
From end-of-life to second life
Typically, end-of-life vehicles (ELV) are shredded in the scrap yard and specific materials, such as tires, cables, batteries and other hazardous materials, are removed manually. After shredding the material is passed through air systems and magnets which separate non-ferrous and ferrous metals. The generated ferrous fraction is then further processed.
Latest advances in Libs technology (Laser-induced breakdown spectroscopy) allow recyclers to take the aluminium fraction to the next level and help the automotive sector achieve its net zero goals. Libs allows post-consumer and post-production scrap to be transformed into individual alloys such as 5.xxx and 6.xxx alloys for example.
Although ELV recycling rates are currently > 95% there is still the age-old problem of ASR (Automobile Shredder Residue). This valuable material is traditionally landfilled or incinerated. The technical plastics which are mainly black and contaminated cannot be separated by traditional sensor-based technology, but technical advancements and legislation-driven incentives will drive the recycling of the most difficult residues. Sorting of brominated flame retardants (BFR) and PVC is already possible and soon sorting black technical plastics into individual polymers will be normal practice.
Regulatory frameworks
Automotive recycling is critical for the industry's efforts in decarbonization, but despite the available technologies, challenges still remain. Overcoming these requires a concerted effort from the entire value chain and policies that help turn the wheel towards greater circularity in the automotive industry.
Numerous factors are impeding a more mindful and sustainable management of ELVs. Vehicles are not designed with recyclability in mind and little recycled content is incorporated into new cars. Moreover, many materials must be imported due to a lack of high-quality materials in sufficient quantities. At the same time, cars go missing and simply disappear and thereby tons of recyclable materials.
To improve end-of-life vehicle management and maximize the efficient use of resources, the European Union discussed amendments to the Directive on end-of-life vehicles (ELV Directive), which we consider very promising and future-forward. The new proposal addresses the entire life cycle of ELVs and advocates for design for recycling, an increase of recycled content, EPR schemes and many more actions that will help collect, recover and recycle more.
Once implemented and adhered to at scale, it is estimated that 12.8 million tons less CO2 will be emitted and 5.4 million tons of high-quality materials will be recycled or reused.2 Intelligent and advanced sorting technology will play a pivotal role in enabling this change. We are committed to leading the resource revolution and supporting the industry's efforts towards greater circularity and decarbonization.
