Comparison of Disinfection technologies for hospital wastes (Chang-Ming et al., 2016; Ghasemi and Yusuff, 2016; Ohtsu et al., 2011; Pei and Wu, 2007; Zhao and Xie, 2018).
| Disinfection technology | Advantages | Disadvantages |
|---|---|---|
| Pyrolysis vaporization incinerator | Complete destruction of toxic and hazardous components | High investment costs and strict demand for heat value of wastes |
| Rotary kiln incinerator | High incineration efficiency with wide range of applications and good adaptability | High dust content in the exhaust, high air demand, high investment and maintenance costs, and low investment recovery |
| Plasma incineration | High energy efficiency with no intermediate products | High requirement of technical personnel and high costs |
| Chemical disinfection | Rapid action, stable performance, and broad sterilization spectrum | Residual disinfectants after disinfection |
| Microwave disinfection | Energy saving, low action temperature, slow heat loss, rapid action, light damage, and low environmental pollution with no residues or toxic wastes | Relative narrow disinfection spectrum and complex impact factors of disinfection |
| High temperature steam disinfection | Low investment and operation costs, simple operation management, and low secondary pollution | Weak odor control |
