In the framework of sustainability, low-carbon chemistry is presuming importance and consequently, infusion of circular economy (CE) concept will play a vital role to encompass the green/sustainable chemistry principles more comprehensively to the resource-dependent chemical industry. In the present state of environmental challenges, retrofitting the chemical industry with sustainable product stewardship is significantly important. This communication details the much-needed transformation of the chemical industry in the framework of circular chemistry (CC) by adopting the CE concept in the context of emerging Industry 4.0. The drivers that enable the circularity and the methodological approach/tools that help to practice circularity in the chemical industry domain are detailed. The CC needs to inherit the CE principles by employing both life cycle and systems thinking approaches, which helps to understand and address the sustainability issues of the chemical processes/products. The application of the CC concept needs a case-specific protocols developed by a well-defined methodological approach.

在可持续性的框架中，低碳化学已成为重中之重，因此，循环经济（CE）概念的注入将发挥至关重要的作用，以更全面地将绿色/可持续化学原理纳入资源依赖型化学工业。在当前的环境挑战中，以可持续的产品监管来改造化学工业非常重要。通过在新兴工业4.0的背景下采用CE概念，本通讯详细介绍了在圆形化学（CC）框架中化学工业急需的转型。详细介绍了启用圆度的驱动因素以及有助于在化工领域实践圆度的方法论/工具。CC需要通过采用生命周期和系统思考方法来继承CE原则，这有助于理解和解决化学过程/产品的可持续性问题。CC概念的应用需要通过明确定义的方法论方法开发的针对特定案例的协议。
