​What is the best method of disposal of hazardous waste?​

Correct option is C

The correct answer is (C) Incineration.

• Incineration is a method of waste management that involves burning solid waste in a furnace to reduce its volume and produce energy. 
• It's the most common way to dispose of hazardous waste, including hospital waste. 

How it works 

• Incinerators burn waste at high temperatures to create ash, heat, and combustion gases
• The combustible parts of the waste combine with oxygen to create carbon dioxide and water
• The inorganic parts of the waste create ash
• The heat produced can be converted into electricity

Benefits

• Incineration can reduce the volume of waste to be disposed of 
• It can destroy microorganisms and render waste unrecognizable 
• It can be used to treat large volumes of infectious waste 

Drawbacks 

• Incineration can release pollutants like dioxins, furans, and nitrogen oxides into the air
• It can release greenhouse gases that contribute to climate change
• The ash residue can contain heavy metals and other toxins
• Incineration facilities can discourage efforts to reduce waste generation and recycle.
