Current volume reduction methods for wasted expandable polystyrene (EPS) foam are summarized and compared each other. Wasted EPS foam has not been recycled effectively because of its large volume to weight ratio. This has prevented from its proper recycling because of high cost of transportation to recycling plant. Successful recycling of wasted EPS foam results directly from successful, i.e. economically and environmentally, volume reduction of wasted EPS foam. This paper deals with various methods for volume reduction methods of wasted EPS foam. Five typical methods of volume reduction are introduced and they are compared each other in terms of expected PS properties after volume reduction, cost effectiveness of each process, possible effects on environment caused by the volume reduction process, and possible recycled products. The methods include thermal, solvent, far infrared and mechanical compaction. Comparison in this paper is made mostly in qualitative manner. The focus in this study is concentrated on summarizing and comparing existing methods of volume reduction for wasted EPS foam.

In study, the lightweight insulation mortar is produced with more than 50,000tons of waste each year, but it is difficult to treat with the degradable composite material and the recycling ratio is still 50%. the lightweight insulation mortar is manufactured by using the ratio of expanded polystyrene and pulverized expanded polystyrene.

The replacement ratio of waste EPS was varied, and its effect on compressive strength and absorption capacity was investigated. According to the experimental results, The 28th day compressive strengths for the W/C 50% specimens were 17.5~21.2MPa, which was relatively low compared to the 13.6~22.2MPa of the W/C 70%.
