Polystyrene (PS) is commonly used to make disposable cups. These cups are lightweight, inexpensive, and offer some insulation. However, they are not environmentally friendly because they are not biodegradable and can contribute to plastic pollution. An alternative is using cups made from biodegradable plastics like PLA (Polylactic Acid), which offer similar utility with less environmental impact.
