The growing demand for sustainable energy in critical facilities such as hospitals necessitates innovative solutions that ensure reliable electricity and heat supply while minimizing environmental impacts. This study introduces a smart energy system specifically designed for Boukan Hospital, uniquely fueled by the hospital’s own waste streams, including municipal-type waste, plastic waste, and a food-waste mixture. The system integrates a steam gasifier, a solid oxide fuel cell, a combustion chamber, compressed air energy storage, and a gas turbine into a coordinated configuration that continuously meets both electricity and partial heating needs. The innovation lies in the intelligent coupling of these units, enabling waste-to-energy conversion with dynamic load management tailored to the hospital’s real demand profile. The methodology combines detailed thermodynamic modeling and regression-based parametric analysis with multi-criteria decision-making. Three key variables were examined: plastic ratio in the feedstock, steam-to-feedstock ratio, and current density. Regression analysis identified nine optimal candidate scenarios, which were optimized using the TOPSIS method and sensitivity analysis of weighting factors, leading to the selection of the most robust scenario. The optimal configuration (Scenario 5) demonstrated remarkable performance, delivering 8719 kWh/day electricity against the hospital’s demand of 8352 kWh/day, while simultaneously recovering 1870 L/day hot water. System efficiency exceeded 42%, and CO2 pollutions were significantly reduced compared to conventional energy supply approaches. The proposed system illustrates a practical and scalable pathway for transforming hospital waste into a reliable source of power and heat. Beyond enhancing energy self-sufficiency and resilience, this smart integration strategy contributes to environmental sustainability, offering a viable model for healthcare facilities in resource-constrained regions.
