Treatment & Disposal
Waste treatment techniques seek to transform the waste into a form that is more
manageable, reduce the volume or reduce the toxicity of the waste thus making the waste
easier to dispose of. Treatment methods are selected based on the composition, quantity,
and form of the waste material. Some waste treatment methods being used today include
subjecting the waste to extremely high temperatures, dumping on land or land filling and
use of biological processes to treat the waste. It should be noted that treatment and
disposal options are chosen as a last resort to the previously mentioned management
strategies reducing, reusing and recycling of waste (figure 1).
