摘要：

This work presents an infectious medical waste-to-energy (IMWtE) thermal and environmental analysis using combined heat and power (CHP) technology. Steam sterilization can be operated with an infectious medical waste (IMW) of 375 kg/h & sdot;unit, a maximum per day of 12,000 kg/day for double sterilization units, and a running time of 16 h/day. The CHP system uses a dried IMW of 797 kg/h, generating a power output of 128.98 kWe, providing a drying heat of 382.91 kW, and achieving an overall system efficiency of 8.45 %. Results are obtained for a life cycle assessment (LCA) of the IMWtE by CHP system technology. The endpoint effectiveness comprises considerations of human health: 2.83E+01 DALY, ecosystem quality is represented value of: 9.32E+00 Species & sdot;y, and natural resource value of: 1.08E+06 USD, all of these are fundamentally linked to the utilization of steel, copper, paint, and gypsum. The LCA impacts are primarily due to the operation phase (93 %), with the smaller contribution of the decommissioning phase (4 %), and the construction phase (3 %), respectively.
