Digital Technologies: Description, Classification, and Links to Circular Economy
通过系统文献综述，识别了24种支持循环经济的关键数字技术，并提出了DATE分类法，分析了这些技术如何促进循环经济策略（如缩小、减缓、闭合和再生资源循环），对研究者和企业有参考价值。
ABSTRACT Digital technologies (DTs) and circular economy ( CE ) are currently two topics that are expected to contribute significantly to sustainable development, and digitization is generally considered a key enabler of CE . However, most studies only cover the most known Industry 4.0 technologies, and very limited research detailing how DTs can support the implementation of CE is available. The first objective of this paper is to fill these gaps by offering an overview of 24 key DTs enablers to CE , thanks to a systematic literature discussion and the development of the DATE (Digital Architecture Type) classification. The second goal is to analyze how these DTs can specifically contribute to the CE strategies of narrowing, slowing, closing, and regenerating. The results demonstrate that DTs can provide a wealth of information regarding production and consumption chains, from micro to global levels. Real‐time diagnostics and forecasting can be obtained for efficient service provision, component lifespan extension and better design practices, besides improved remanufacturing, recycling, and refurbishment approaches. To inform future research, significant gaps in the literature and new research initiatives are addressed.
