Plastics have numerous properties that render them superior to other materials in many applications. Since the past 50 years, the use of plastics has dramatically increased in our daily lives. However, household refuse and industrial disposal of plastic materials is a major environmental concern. Because of legal requirements, which have been enforced to protect the environment, there is a pressing need to develop methods to recycle plastic waste. Mechanical recycling has emerged as the most economical, as well as the most energetic and ecologically efficient option. After introducing the mechanical recycling concept, this review will focus on the strategies that have been used for compatibilization of blends of mixed thermoplastic waste.

塑料具有许多特性，使其在许多应用中优于其他材料。自过去的50年以来，塑料的使用在我们的日常生活中急剧增加。然而，家庭垃圾和塑料材料的工业处置是主要的环境问题。由于为了保护环境而强制执行的法律要求，迫切需要开发回收塑料废物的方法。机械回收已成为最经济，最具活力和生态效率最高的选择。在介绍了机械回收概念之后，本文将重点讨论已用于使热塑性废塑料混合料相容化的策略。
