The increasing awareness of waste circular economy has motivated valorization strategies for minimizing resource consumption and waste production in the private sector. With the rise of various industrial wastes and with the emergence of COVID-19 wastes, a sustainable approach is needed to mitigate the growing concern about wastes. Thermochemical treatment technologies in the form of direct combustion, torrefaction, pyrolysis, and gasification have been identified to have vital roles in the value-creation of various waste streams. Moreover, the alignment of thermochemical processes for waste mitigation concerning the circular economy framework needs to be established. Accordingly, a comprehensive review of the different thermochemical treatment options for industrial and the novel COVID-19 medical wastes streams is conducted in this study. This review focuses on highlighting the instrumental role of thermochemical conversion platforms in achieving a circular economy in the industrial sector. Various strategies in waste mitigation through various thermochemical processes such as management, recovery, reduction, and treatment are discussed. The results show that thermochemical technologies are beneficial in addressing the sustainability concerns on mitigating wastes from the industrial sector and wastes brought by the COVID-19 pandemic. This also includes the current issues faced as well as future perspectives of the thermochemical conversion technologies.
日益增强的循环经济废物意识促使私营部门采取了各种增值策略，以最大限度地减少资源消耗和废物产生。随着各种工业废物的增加以及 COVID-19 废物的出现，需要采取可持续的方法来减轻人们对废物日益增长的担忧。直接燃烧、热解、热解和气化等形式的热化学处理技术被认为在各种废物流的价值创造中起着至关重要的作用。此外，需要确定针对循环经济框架的废物减排的热化学工艺的一致性。因此，本研究对工业和新型 COVID-19 医疗废物流的不同热化学处理选择进行了全面审查。本综述重点强调了热化学转化平台在实现工业部门循环经济方面的重要作用。讨论了通过各种热化学工艺（如管理、回收、减少和处理）来减轻废物的各种策略。结果表明，热化学技术有利于解决工业部门废物和 COVID-19 大流行带来的废物的可持续性问题。这还包括热化学转化技术当前面临的问题以及未来展望。
