    waste?
    A Landfills Correct Answer Incorrect Answer
    B Ocean dumping Correct Answer Incorrect Answer
    C Incineration Correct Answer Incorrect Answer
    D Composting Correct Answer Incorrect Answer

    Solution

    Incineration is considered the most effective method for hazardous waste disposal. This process involves combusting waste materials at high temperatures (800-1200°C), which reduces waste volume by up to 90% while destroying harmful pathogens and toxic compounds. The heat generated during incineration can be harnessed for electricity production, creating an energy recovery benefit. Modern incinerators incorporate advanced emission control systems to minimize environmental concerns such as air pollutants. While incineration does produce ash residue that requires safe disposal, it remains superior to alternatives like landfills (which risk groundwater contamination), ocean dumping (prohibited by international conventions), or composting (unsuitable for hazardous materials).
