Abstract: The consumption of Polystyrene (PS) results in the generation of a large quantity of PS plastics waste. The recycling of waste PS to its original products or other low graded products is not usually economically sustainable. A promising solution to this problem is to recycle the waste PS to highly value-added products. The objective of the present study is therefore to develop new technologies to reclaim waste PS into functional polymeric beads or micro-particles, which can be developed into novel adsorbents. A new method was developed for the preparation of polymeric micro particles from PS solutions. The micro-granules were further functionalised by surface coating and were studied as adsorbents for heavy metal removal. In addition, waste PS was reclaimed and further remolded into porous beads, which were further functionalized as adsorbents and were studied for humic acid removal.
