上世纪90年代以来,世界性的环境污染日趋严重,废弃的汽车也成为一大污染源,全世界现有近八亿辆废弃汽车。每年要占用五六百平方公里的土地,来停放五六千台的报废汽车,这样浪费了大量的土地面积。为了解决土地占用的问题,就要对报废汽车进行拆解,但是拆解不当又会对环境造成污染,因为报废汽车里含有多种重金属、废液、塑料。 Since the 1990s, global environmental pollution has become increasingly serious. Abandoned vehicles have also become a major source of pollution. There are nearly 800 million abandoned vehicles in the world. Each year to occupy five or six hundred square kilometers of land to park five or six thousand sets of scrapped vehicles, thus wasting a lot of land area. In order to solve the problem of occupation of land, it is necessary to dismantle the scrapped vehicles. However, improper disassembly will pollute the environment because scrapped cars contain a variety of heavy metals, waste liquids and plastics.
