Incineration is the preferred method for hazardous waste disposal because it reduces waste volume while generating energy. The process involves burning waste at high temperatures to create ash, heat, and combustion gases. The heat produced can be converted into electricity. Incineration effectively destroys microorganisms and can treat large volumes of infectious waste, making it particularly suitable for hospital waste. However, it does have drawbacks, including the potential release of pollutants and greenhouse gases.
