Polystyrene (PS) accounts for approximately 3% of the plastic packaging market. The main applications of non-foamed PS are trays, cups and bottles, while foamed PS is mainly used for disposable food packaging, such as hot drink cups and flip-top packaging, food trays, for buffering or protecting objects during transportation.
Today, the recovery rate of PS is very low. First, since many applications of PS packaging are related to food, the material is often contaminated. Secondly, due to the large volume of EPS (low density), it directly affects the cost of collection and transportation.
