Complete step by step answer:
A paper cup is a disposable cup made out of paper and often lined or coated with plastic or wax to prevent liquid from leaking out or soaking through the paper. Disposable cups are made up of Polystyrene (PS).
The main advantages of polystyrene cups are:
1.They use fewer raw materials.
2.Their manufacturing process consumes less energy and produces less waste than that of paper cups.
3.Polystyrene cups are also lighter than paper ones, which leads to lower transport costs.
