汽车制造商从失事车辆中回收许多材料，但处理较轻的部件越来越困难。填埋的高成本使得焚烧的选择更具吸引力，因为它减少了废物的质量和体积。能量回收也是可能的。本文探讨了这些属性的汽车撕碎机残留物（ASR），这是相关的污染物在焚烧过程中形成。ASR的较高比能为19，000 kJ/kg，灰分含量为38%，这表明它是城市焚烧炉或水泥窑的合适燃料。然而，它是非常不均匀的，因为低密度部分主要由塑料组成，还有少量的金属碎片，橡胶，玻璃和木材。测定ASR代表性样品的宏观组成。通过特殊技术分析了金属和氯的含量，发现分别为馏分的22%和3.5%。目前正在计划对ASR进行实验室规模的焚烧试验。© 1997 ISWA
Car manufacturers recycle many of the materials from wrecked vehicles, but the disposal of the lighter components is increasingly difficult. The high cost of landfill is making the option of incineration more attractive, as it reduces the mass and the volume of the waste. Energy recovery is also possible. This paper examines those properties of automotive shredder residues (ASR) which are relevant to the formation of pollutants during incineration. The higher specific energy of ASR was found to be 19,000 kJ kg and the ash content 38%, which indicate that it is a suitable fuel for municipal incinerators or cement kilns. However, it is very heterogeneous, as the low density fraction is mainly composed of plastics, with smaller amounts of metallic pieces, rubber, glass and wood. The macroscopic composition of a representative sample of ASR was determined. The metal and the chlorine contents were analysed by special techniques and were found to be 22% and 3.5%, respectively of the fraction. Laboratory-scale incineration trials of ASR are now planned. © 1997 ISWA
