One advantage of the waste-incineration process is that it reduces the weight and volume of the waste. This process results in a less hazardous amount of waste. The gas and residue that incineration produces, such as slag and ash, is odorless.
Another advantage is that waste incineration requires less land area as compared to waste-disposal sites.
A disadvantage of waste incineration is that flue gases produced during this process contain residues that can pollute the environment. Also, the amount of energy produced by incineration can only serve a small town. Incinerated waste produces ash that contains toxins. If not handled properly, these toxins can lead to environmental problems when toxicity levels become high.
