Polystyrene, a versatile and widely employed thermoplastic polymer, is derived from the polymerization of styrene monomers. Existing in both solid and foam forms, solid polystyrene is transparent, rigid, and extensively utilized in packaging materials, disposable containers, and consumer goods. On the other hand, expanded polystyrene (EPS) foam, known for its lightweight and insulating properties, finds application in construction for thermal insulation.

Its versatility extends to crafting, modeling, and the manufacturing of consumer electronics. Polystyrene’s cost-effectiveness and ease of molding make it a popular choice for disposable items like cups, plates, and food containers. Despite its widespread use, environmental concerns exist due to its non-biodegradable nature. Research efforts are ongoing to enhance polystyrene recycling and explore sustainable alternatives, reflecting a broader industry trend towards more environmentally conscious material choices.
