Polystyrene food containers

Polystyrene trays can't be recycled. Try and avoid buying food and drink which comes in polystyrene! If you can't, put the containers in your rubbish bin. Polystyrene often isn't recycled because it is difficult to sort from other types of plastic waste and easily breaks into small beads which can clog up sorting machines and cause them to break down.
