Explanation
Incineration manages waste by oxidising and burning it through high-temperature thermal treatment.
Flotation is a wet separation process, not a thermal one.
Sludging concerns the settling of solids in liquid, not burning.
Composting is biological decay of organic matter, not combustion.
Incineration greatly reduces waste volume and can recover heat energy.
Its flue gases must be cleaned to control dioxin and particulate emissions.
