Automotive shredder residue

Automotive shredder residue

The shredding of automobiles and major household appliances is a process where a hammermill acts as a giant tree chipper by grinding the materials fed into it to fist-size pieces. The shredding of automobiles results in a mixture of ferrous metal, non-ferrous metal (e.g. alloys of copper and aluminium) and shredder waste, called automotive shredder residue or automobile shredder residue (ASR). Auto shredder residue: separation and sorting for every Following separation of the non-ferrous metals, the residual shredder light and heavy fractions (SLF/SHF) form what is known as the automotive shredder residue (ASR) fraction. To recover the valuable residues contained in the ASR, and thus to adhere to the statutory recycling rates, the use of high-efficiency separation and sorting technology is vital.
