The increasing amount of shredded automobile residues has generated a new policy to their disposal and treatment. Accordingly, a complete knowledge of the residues characteristics is of great importance to cope with the soil pollution and the shortage of land filling space.
Following this goal, the present study is also a first step in the process of reducing the shredded automobile residues and stabilizing hazardous substances. It was then found that the shredder residues are composed of cottons and sponges like metals, plastics, rubbers, glasses and small stones, metals, and electric wires. In addition the weight percentage of organic materials is about 70%. It is worth noticing that in small and large particle size fractions the lead contamination is relatively low but cotton and sponge like materials include more lead inclusions than any other components. These inclusions do not have an ion origin. There are fine particles, mainly in the range of 0.1-1.0 μm, as shown in the lead determination analysis using different filters.
