Recycling and Recovery

Expanded Polystyrene is completely recyclable.

How is EPS recycled?

Segregation
EPS scrap must be segregated from other materials in the waste stream before it can be recycled. Ideally the EPS should be separated before it enters the waste stream to minimise contamination and so as to not take up bin capacity for other recyclable materials.

Collection
Since EPS is lightweight, transportation cost is a major component of its recycling. The material handling requirements for EPS scrap are usually determined by the recycler. Most commonly EPS scrap is either bagged in loose form or baled prior to transport.

Reprocessing
The collected EPS is fed into a granulation machine. The granulated material is then fed to a hopper where it is stored before being compressed into continuous lengths. This compressed material is broken into lengths suitable for palletisation. Once palletised the material is ready for shipment. 

Converting EPS into other products
Once exported, the EPS material is then shredded and then extruded to form General Purpose Polystyrene (GPPS) pellets. This can then be used as a feedstock for applications such as synthetic timber, cd and video casette cases, stationery products as well as plant pots and coathangers.
