Mechanochemistry is defined to describe the chemical and physicochemical transformation of substances during the aggregation caused by the mechanical energy. Mechanochemical technology has several advantages, such as simple process, ecological safety and the possibility of obtaining a product in the metastable state. It potentially has a prospective application in pollution remediation and waste management. Therefore, this paper aims to give an overall review of the mechanochemistry applications in waste management and the related mechanisms. Based on our study, the modification of fly ash and asbestos-containing wastes (ACWs) can be achieved by mechanochemical technology. Waste metal oxides can be transformed into easily recyclable sulfide by mechanochemical sulfidization. Besides, the waste plastics and rubbers, which are usually very difficult to be recycled, can also be recycled by mechanochemical technology.
机械化学被定义为描述物质在机械能引起的聚集过程中发生的化学和物理化学转化。机械化学技术具有几个优点，例如工艺简单、生态安全以及获得亚稳态产物的可能性。它在污染修复和废物管理方面具有潜在的应用前景。因此，本文旨在全面综述机械化学在废物管理中的应用及相关机理。根据我们的研究，机械化学技术可用于对粉煤灰和石棉废物（ACWs）进行改性。可通过机械化学硫化将废金属氧化物转化为易于回收的硫化物。此外，通常很难回收的废塑料和橡胶也可以通过机械化学技术进行回收。
