POLYSTYRENE

POLYSTYRENE

You’ve seen polystyrene most often in its expanded form – actually a solidified foam obtained from liquid polystyrene – but also in various objects like disposable cutlery or CD cases. Expanded polystyrene (EPS) is commonly used to make disposable coffee cups or soup bowls.
 
How is it recycled?
 
Mostly, the process is similar to recycling of other types of plastic. Because expanded polystyrene is actually a low density foam, it’s usually compacted prior to recycling. The recycling process is the same as with other plastics – sorting, washing, grinding, melting, and then extruding the material into pellets. Polystyrene can also be incinerated, a procedure that results in water vapors and carbon dioxide, which makes it an excellent solution for waste-to-energy generation.
 
What are the advantages of recycling?
 
When it is discarded in nature, expanded polystyrene poses a threat to wild birds and water fauna; because of its low density, it can float or be carried away by the wind. Polystyrene fragments are lethal to fish and birds that eat them. Like the other types of plastics, it is produced from natural resources, lasts a long time, and therefore is a major source of pollution.
 
What can I recycle?
 
It is unlikely you’ll have something to recycle; polystyrene has mostly industrial uses, mainly in constructions, for the heat insulation of outer walls. Because it is very light relative to its volume, collecting polystyrene for recycling is only efficient in large quantities. But if you own a small company and don’t have an idea how to get rid of polystyrene cups in a way that helps the environment, SIGUREC is always close to you!
