There are many industrial waste streams that currently are being deposited in landfills despite having the potential to be recycled and converted into useful products. A good example of this is automobile industry machining operations, which generate finely divided metal particles ("swarf"). Swarf has a very high iron content and great potential for re-use. However, it has a tendency to spontaneously oxidize, which leads to self-heating and obstructs recycling efforts. There is a need to limit the self-heating of swarf, but such control is difficult, because little information is available about the physical characteristics of swarf. Hence, the objective of this study was to determine the properties of swarf and to identify promising methods to prevent spontaneous heating. The properties examined were particle morphology, composition, size distribution, and surface properties.
目前有许多工业废物流尽管有潜力被回收利用并转化为有用产品，但仍被填埋。汽车工业机械加工操作就是一个很好的例子，其会产生细碎的金属颗粒（“切屑”）。切屑含铁量非常高，具有很大的再利用潜力。然而，它有自发氧化的倾向，这会导致自热并阻碍回收工作。需要限制切屑的自热，但这种控制很困难，因为关于切屑物理特性的信息很少。因此，本研究的目的是确定切屑的特性，并找出有前景的防止自发加热的方法。所研究的特性包括颗粒形态、成分、尺寸分布和表面特性。
