Automotive Shredder Residue (ASR)
Huichuan Automotive Shredder Residue Recycling Solution — One-stop Separation and Sorting for All ASR Processing Scenarios in Recycling End-of-Life Vehicles (ELVs)
A car is a typically complex end-of-life product, containing approximately 10,000 components and over 40 different materials. Compared to the 1990s, when medium-sized cars were composed of over 70% steel, the proportion of lightweight materials (such as aluminum alloys and polymers) is now increasing significantly — a trend that adds complexity to automotive recycling, asr recycling, and the operation of automobile shredder systems in processing End-of-Life Vehicles (ELVs), especially in critical steps like zorba sorting.
In conventional automobile shredder and car scrap machine workflows for ELVs, shredded materials are first processed by air separation, followed by the separation of steel components. The floatable light fraction produced by air separation is called "Shredder Light Fraction (SLF)"; the heavy fraction after air separation, once ferrous metals are removed, is known as "Shredder Heavy Fraction (SHF)".
To separate most of the recyclable non-ferrous metals from these fractions — a key step in maximizing resource recovery during ELV recycling and the core of zorba sorting — Huichuan’s ECS eddy current separators have been validated through decades of global practice. As a leading zorba sorting machine, Huichuan’s non-ferrous metal separators, equipped with an eccentric magnetic pole system, can stably separate high-purity non-ferrous metal fractions (ZORBA) even under extreme working conditions. The Huichuan ECS  series integrate decades of technical accumulation and innovative designs — such as time-saving belt replacement structures and efficient sorting functions for fine-grained materials — making them the ideal zorba sorting machine for both standalone operation and integration into compact modular systems. They seamlessly fit into car scrap machine lines and automobile shredder workflows, while laying a foundation for subsequent asr recycling.
After separating non-ferrous metals via zorba sorting, the remaining Shredder Light Fraction and Heavy Fraction (SLF/SHF) together form "Automotive Shredder Residue (ASR)" — a critical byproduct in recycling End-of-Life Vehicles (ELVs). ASR, which accounts for about 15%-25% of the shredded automotive materials, is a complex mixture that poses challenges for asr recycling and requires specialized technology to unlock its value. To recover valuable components from ASR and meet statutory recycling rate requirements for ELVs, efficient separation and sorting technologies are crucial.
As a metal recycling solution expert with profound accumulation and continuous innovation, Huichuan provides a comprehensive range of sorting equipment combinations to cover various processing needs in ELV recycling, automobile shredder downstream processing, asr recycling, and zorba sorting:
Huichuan’s induction sorting system features high sensitivity and strong adaptability, enabling precise separation of pure metal components and residues. It is an ideal preprocessing equipment for car scrap machine output, a key link in asr recycling, and a vital part of ELV recycling workflows — complementing the efficiency of zorba sorting machine operations.
Huichuan’s combined sorting system is equipped with multiple sets of intelligent linked sensors, which can be flexibly configured according to specific tasks and scenarios. Whether the goal is to obtain pure cable fractions (ICW) or high-purity metal fractions such as ZURIK and TWITCH, the Huichuan series can provide adapted solutions for various ASR processing scenarios in ELV recycling, enhancing the efficiency of automobile shredder downstream lines, maximizing resource recovery in asr recycling, and optimizing the output quality of zorba sorting.
For the reprocessing of metal-free shredder residues from ELVs — a core challenge in asr recycling — Huichuan also offers a complete solution:
With Huichuan’s sorting system, market-valuable plastic products can be separated from ASR, and impurities such as wood can be efficiently removed. Even for black mixed plastics, individual plastic components such as PP, PE, PVC, and PS/ABS can be sorted out — a breakthrough that traditional near-infrared technology struggles to achieve, but Huichuan’s technology can easily accomplish. This not only elevates asr recycling efficiency but also complements automobile shredder, car scrap machine, and zorba sorting machine operations, further boosting the circular economy value of ELV recycling.
