Many people are not aware that polystyrene is recyclable. But it actually is very easy to recycle.
High density compressed polystyrene is easy to process into new plastic or foam products. Polystyrene is reused in almost every plastic product imaginable, from mobile phones, speakers, TVs, and toys. Reusing polystyrene is much cheaper – and more environmentally friendly – than producing new plastic.
This means that polystyrene is a very sought-after commodity that is very popular in e.g. China where a lot of plastic is needed for production.
