This article addresses the implementation of digital twin (DT) technology in concrete plants, focusing on the integration of sensor data, real-time monitoring, predictive maintenance, and operational simulations as part of the evolution of Industry 4.0. The technology collects necessary data from numerous plant components to create a constantly updated virtual model, i.e. DT of the real concrete plant, enabling dynamic simulations and analysis. Real-time analytics enable rapid operational adjustments that increase efficiency and reduce waste. In addition, the DT serves as an effective training tool, providing risk-free scenarios for new operators. Implementing DT improves operational visibility and maintenance forecasting and increases operational efficiency, which in turn leads to cost reductions and higher safety standards. The paper highlights the role of DT in the evolution of traditional manufacturing processes through improved digital integration. A representative example from an actual mid-sized concrete plant supported by a DT is given, demonstrating improvements in the operation and maintenance of such a production facility.
