Although the use of plastic components is increasing in the automotive industry, yet the recovery rates of these materials in end-of-life vehicle (ELV) is lower compared to metals. One of the main problems of ELV plastic waste is poor separation and sorting. Large car plastic parts consist of fibre-reinforced plastics, whereas other components end up in the automotive shredder residue (ASR), featuring a very heterogeneous mix of light materials that contains mostly non-metallic materials such as textiles, plastics, cartridges and wood. Generally, ASR was disposed in landfill or diverted to thermal treatments, such as pyrolysis or gasification, for energy recovery. Currently, the recovery of raw materials from various waste streams plays a key role in new European strategy for plastics in a circular economy. The approach of physical recycling methods described in this mini-review helps to maintain the value of polymer materials in the value chain allowing the reuse in the original or similar application.
虽然塑料部件在汽车行业的使用正在增加,但与金属相比,这些材料在报废车辆(ELV)中的回收利用率较低。ELV 塑料废物的主要问题之一是分离和分类不佳。大型汽车塑料部件由纤维增强塑料组成,而其他部件则最终成为汽车破碎机残渣(ASR),其中包含混合了大量轻材料的非常不均匀的混合物,主要是非金属材料,如纺织品、塑料、墨盒和木材。通常,ASR 被处置在垃圾填埋场或转移到热解或气化等热处置方法中,以回收能源。目前,从各种废料流中回收原材料在新的欧洲循环经济塑料战略中发挥着关键作用。本综述中描述的物理回收方法的方法有助于在价值链中保持聚合物材料的价值,允许在原始或类似应用中再利用。
