To stabilize plant operations and reduce labor through a decrease in manual intervention in waste-to-energy plants, Mitsubishi Heavy Industries Group has implemented the Navigator automated operation system, a core feature of the MaiDAS® integrated plant operation system, along with operational monitoring and anomaly detection functions at a large-scale overseas waste-to-energy plant. The system commenced operations in October 2024 across all four incinerators at the target facility, following remote analysis and on-site adjustments. Since implementation, a high application rate of 94% (ratio of MaiDAS®-operated hours to total operating hours) has been maintained, with manual operations reduced by approximately 76%. Furthermore, control performance of the main steam flow rate and flue gas concentrations was confirmed to be equal to or exceeding manual control by operators. Consequently, an operational structure reduced to one operator per shift was realized in January 2025, achieving labor savings.
