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). ASR consists of glass, fiber, rubber, automobile liquids, plastics and dirt. ASR is sometimes differentiated into shredder light fraction and dust. Sometimes these residual materials are called "Car-fluff".
ASR often contains hazardous substances such as lead, cadmium, and PCB. Therefore, some countries have classified ASR as hazardous waste and have established legislative controls.
==Recycling==
It is estimated that every year in EU nations nearly 3 million tonnes of automotive shredder residue (ASR) are generated. While half of the waste which contains rubber, textiles and plastics can transferred into alternative fuels or recycled, remaining portion is primarily land-filled. The European Draft directive 2000/53/CE states that by the year 2015, only 5% of the vehicle's weight can be disposed of at landfill sites.
