Expanded Polystyrene is completely recyclable. Over the past decade, REPSA has established a National Collection Network to facilitate EPS recycling in Australia, including Polystyrene Recycling Queensland. There are a variety of uses recycled EPS can be put to:
- EPS can be granulated and mixed in with virgin material to make new products and some grades of EPS insulation board and block moulded EPS can incorporate recycled content.
- EPS granulate can also be used on its own and mixed in with plaster or concrete to make a lightweight building material.
- Used EPS can be ground and mixed with soil and compost to promote aeration. Studies confirm that plant growth is enhanced with this aeration.
- EPS can also be melted and converted to General Purpose Polystyrene (GPPS) pellets and used to manufacture simple polystyrene products such as coat hangers, video cassette and cd casings, stationery items and plant pots.
