废塑料的再生利用可分为简单再生利用和改性再生利用两大类。简单再生利用是指将回收的废塑料制品经过分类、清洗、破碎、造粒后直接加工成型。改性再生利用是根据不同废塑料的特性加入不同的改性剂，使其转化成高附加值的有用材料。废塑料经过改性后，机械性能得到改善或提高，可用于制作档次较高的塑料制品。塑料废物资源化，既可以节省和利用资源，降低处理费用，又可消除或减轻废塑料对环境的影响，是近年来废塑料资源化研究的焦点。资源化方法包括：油化再生、高炉喷吹、与煤共焦化和固体燃料热能利用技术(RDF)等。
The recycling of waste plastics can be divided into two categories: simple recycling and modified recycling. Simple recycling means that the recycled waste plastic products are processed directly after classification, cleaning, crushing and granulation. According to the characteristics of different waste plastics, different modifiers are added to transform them into useful materials with high added value. After modification, the mechanical properties of waste plastic are improved or raised, and it can be used to make plastic products of higher grade. Recycling of plastic waste can save and utilize resources, reduce treatment costs, and eliminate or reduce the impact of waste plastic on the environment, which has become the focus of research on recycling of waste plastic in recent years. Recycling METHODS INCLUDE: OIL REGENERATION, BLAST furnace INJECTION, COCOKING WITH COAL, SOLID FUEL THERMAL ENERGY UTILIZATION TECHNOLOGY (RDF), etc.
