Increased mobility and the soaring worldwide demand for cars have opened up questions regarding sustainability and environmental protection. Hazardous exhaust gases are emitted not only when driving vehicles, but also during their production. The waste gas volumes in the automotive industry reach up to 200,000 Nm³/h.
Dismantled ELVs (End of Life Vehicles) are sold to shredder operators and are reduced to fist-size pieces by large rotating hammer mills. The Shredder Light Fraction (SLF) is removed from the stream by suction, the intensity of which determines the amount and composition of the SLF. SLF consists essentially of plastics/rubber (~60%), Glass/sand i.e. mineral substances (~15%), Textiles/leather/wood (~10%), Paint dust/rust (~10%) and Residual metals (~5%). Other names for SLF are ASR (Automobile Shredder Residue)...
The value of Zorba – shredded non-ferrous metals originating from end-of-life vehicles or WEEE – continues to increase, as the demand for copper, nickel and brass created by modern lifestyles is on the rise. TOMRA’s sensor-based sorting technology can double the value of Zorba.
Polycyclic Aromatic Hydrocarbons (PAHs) are a group of over 100 different chemicals that are known to be formed typically during incomplete combustion of organic matter at high temperature. Their major sources in the atmosphere include industrial processes, vehicle exhausts, waste incinerations, and domestic heating emissions. Due to their carcinogenic/mutagenic effects, 16 PAHs are currently listed as priority air pollutants.
