Abstract The objective of the study was to analyse how the integration of Industry 4.0 technologies can promote circular practices within supply chains, aiming for efficiency, transparency and sustainability. The theoretical framework of the research included concepts from Industry 4.0, sustainability, circular supply chains and emerging technologies, underpinning the analysis of the integration of these elements. The research was conducted through a systematic literature review, analysing 28 articles published between 2017 and 2024 that discussed the integration of Industry 4.0 technologies into circular supply chains. The results indicate that the integration of Industry 4.0 technologies predominantly occurs through the paradox of economic growth, efficiency, and technological innovation. This integration aids in promoting circular practices by identifying waste, opportunities for material reuse, tracking waste and by‐products and predicting product demand with greater accuracy, among other benefits. The conclusion of the research highlights the importance of sustainability, innovation and interdisciplinary collaboration in driving more efficient and sustainable practices within supply chains. The contributions include the expansion of knowledge on the integration of Industry 4.0 technologies into circular supply chains, the identification of opportunities for future research, the encouragement of interdisciplinarity and collaboration, and the promotion of more efficient and sustainable practices across various sectors of the economy.
