Type #6 PS (Polystyrene) is an example of plastic that cannot be recycled in Singapore. These are usually lightweight plastics commonly used for food packaging, disposable containers and styrofoam products. Recycling of Type 6 plastics is not widely available worldwide and recycling plants in Singapore do not accept them. Due to its material composition, it is also not worth the cost of sending them to recycling plants overseas.
