Auto Shredder Residue (ASR)

Every year, millions of vehicles reach the end of their life and become waste. If end-of-life vehicles (ELVs) are not properly processed, they can lead to environmental hazards and result in the loss of millions of tonnes of valuable materials, impacting both sustainability and the economy.

The automotive manufacturing industry is one of the largest consumers of primary raw materials such as steel, aluminum, copper, and plastics, yet it makes limited use of recycled materials. While ELV recycling rates are generally high, the quality of recovered scrap metals remains low.

SGM offers a comprehensive range of advanced solutions for recovering ferrous materials from shredders, as well as extracting non-ferrous metals from Auto Shredder Residue (ASR).

With multiple global references among car shredder operators, SGM is a world leader in providing cutting-edge separation technologies that maximize both metal recovery and purity, ensuring higher efficiency and sustainability in ELV recycling.

The best solution is often a combination of best technologies.

Drum Magnets

For cleaning and recovering the ferrous coming off the shredder, SGM offers a complete range of mid, large and Mega axial pole drum magnets provided with anodized aluminum strip winding for maximum performance and heat dissipation.

Special proprietary Polishing Drum Magnets are offered for further processing of the ferrous and reduction of the copper content, coming from electrical rotors (“meat balls”) in the ferrous, from the typical 0.3% to below 0.2%.

ASR Processing for Non-Ferrous Metal Recovery

For the recovery of non-ferrous metals from Auto Shredder Residue (ASR), SGM provides a comprehensive range of advanced separation technologies, including:

Eddy current separators
Sensor-based separators
Air gravity classifiers and tables
Sand media gravity sorters
Color sorters
X-ray sorters

For further processing of Zorba recovered from ASR, SGM offers a dry alternative to traditional wet media plants. This solution combines screens, X-ray sorters, and specialized air gravity tables to effectively separate light metals (aluminum and magnesium) from heavier metals (copper, brass, lead, zinc, etc.), ensuring higher recovery rates and improved material purity.
