Environmental risks of polystyrene waste:

EPS is the expanded polystyrene which is known as Styrofoam which is widely used in packaging. Despite the wide application of polystyrene, polystyrene waste is not completely disposable. It is non-biodegradable takes thousands of years to decompose. Burning of polystyrene waste affects the environment as toxic gases are released in the environment and mix with the air. These toxic gases in the atmosphere react with oxygen, water and other gases and formed acidic pollutants which is acid rain. And it has adverse effect on global warming and ozone depletion.

Step 3

Social risks of polystyrene waste:

For good health, atmosphere should be clean and fresh. To keep atmosphere clean and fresh treatment of toxic gases is necessary. When EPS wastes are burnt in air, toxic gases are r...
