Question

Hospital wastes are disposed through

• A. Scrubbers
• B. Electrostatic precipitators
• C. Catalytic converters
• D. Incinerators

Hint:

Hospital waste is hazardous and requires methods that safely destroy pathogens and reduce volume. Incineration achieves both by high-temperature combustion.

Answer 1

The Correct Option is D

Step 1: Understand the nature of hospital waste

Hospital waste, also known as biomedical waste or healthcare waste, often contains infectious materials, sharp objects, pathological waste, and sometimes chemical or pharmaceutical waste. Due to its hazardous nature, it requires specific and safe disposal methods to prevent the spread of diseases and environmental contamination.

Step 2: Evaluate the provided options for hospital waste disposal

• Scrubbers: Scrubbers are air pollution control devices that remove particulates and gases from industrial exhaust streams. They are used for treating gaseous emissions, not for the primary disposal of solid waste.
  This option is incorrect for the primary disposal of hospital waste.
• Electrostatic precipitators: These devices remove fine particles, like dust and smoke, from a flowing gas using electrostatic charge. They are air pollution control devices, not direct waste disposal methods.
  This option is incorrect for the primary disposal of hospital waste.
• Catalytic converters: Used in vehicle exhaust systems to convert toxic pollutants into less toxic ones. Not related to hospital waste disposal.
  This option is incorrect.
• Incinerators: Incineration involves combustion of organic substances in waste. It is highly effective for disposing of infectious and hazardous hospital waste because the high temperatures sterilize the waste and significantly reduce its volume.
  This option is correct.

Step 3: Conclusion

Incineration is the primary and most appropriate method among the given options for the disposal of hazardous hospital waste.

The final answer is: Incinerators.
