Cost–Benefit Analysis of Introducing Custom-Made Small Thermal-Frictional Sterilization System to the Existing Hospital Waste Disposal System: A Case Study of Chinese Hospital

This manuscript proposes an integrated system for treating hospital solid waste (H.S.W.) consisting of incineration and frictional sterilization capable operating during normal emergency situations. We analyzed the benefits integrating different treatment systems with existing stand-alone system, a particular emphasis on thermal friction integration system. The objective was to define economic advantages in terms resources recovery using sterilization–incineration hospital’s emergency/pandemic conditions. modeled three modeling scenarios based results show that H.S.W. composed 74% general Existing would be most expensive process because sanitary transportation cost represented approximately 96% costs. realize 40–61% savings relative method if incineration–frictional were implemented treat 50–70% H.S.W.; better than other scenarios. Proposed scenario 3 had much factor 1 2. study showed could work well even under conditions in-house sorting/transportation/storage is modified cater treatment/sterilization systems.
