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.

COVID-19 和通过热化学技术减少工业废物以实现循环经济:最新评论

对废物循环经济的认识不断提高,推动了私营部门最大限度地减少资源消耗和废物产生的价值战略。随着各种工业废物的增加和 COVID-19 废物的出现,需要一种可持续的方法来减轻对废物日益增长的担忧。直接燃烧、烘焙、热解和气化形式的热化学处理技术已被确定在各种废物流的价值创造中具有重要作用。此外,需要建立与循环经济框架相关的减少废物的热化学过程的一致性。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方案进行了全面审查。本综述重点强调热化学转化平台在工业部门实现循环经济中的重要作用。讨论了通过各种热化学过程(例如管理、回收、减少和处理)减少废物的各种策略。结果表明,热化学技术有助于解决减轻工业部门废物和 COVID-19 大流行带来的废物的可持续性问题。这还包括当前面临的问题以及热化学转化技术的未来前景。讨论了通过各种热化学过程(例如管理、回收、减少和处理)减少废物的各种策略。结果表明,热化学技术有助于解决减轻工业部门废物和 COVID-19 大流行带来的废物的可持续性问题。这还包括当前面临的问题以及热化学转化技术的未来前景。讨论了通过各种热化学过程(例如管理、回收、减少和处理)减少废物的各种策略。结果表明,热化学技术有助于解决减轻工业部门废物和 COVID-19 大流行带来的废物的可持续性问题。这还包括当前面临的问题以及热化学转化技术的未来前景。
