Today, the scientific community is facing crucial challenges in delivering a healthier world for future generations. Among these, the quest for circular and sustainable approaches for plastic recycling is one of the most demanding for several reasons. Indeed, the massive use of plastic materials over the last century has generated large amounts of long-lasting waste, which, for much time, has not been object of adequate recovery and disposal politics. Most of this waste is generated by packaging materials. Nevertheless, in the last decade, a new trend imposed by environmental concerns brought this topic under the magnifying glass, as testified by the increasing number of related publications. Several methods have been proposed for the recycling of polymeric plastic materials based on chemical or mechanical methods. A panorama of the most promising studies related to the recycling of polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), and polystyrene (PS) is given within this review.
如今，科学界在为子孙后代创造一个更健康的世界方面面临着严峻挑战。其中，寻求塑料回收的循环和可持续方法因多种原因而成为最具挑战性的任务之一。事实上，上个世纪塑料材料的大量使用产生了大量持久性废物，长期以来，这些废物一直未成为适当回收和处置政策的对象。这些废物大部分是由包装材料产生的。然而，在过去十年中，环境问题引发的新趋势将这个话题置于放大镜下，相关出版物数量的增加就是证明。已经提出了几种基于化学或机械方法回收聚合塑料材料的方法。本综述给出了与聚乙烯（PE）、聚丙烯（PP）、聚对苯二甲酸乙二酯（PET）和聚苯乙烯（PS）回收相关的最有前景研究的全景。
