Research on key techniques of waste polystyrene foam recycling

The recycling profiles,source and classification,recycling methods,the technology bottleneck of abandoned polystyrene(PS) foam plastics were introduced in this paper.And it mainly discussed the process and progress of recycling and modification of abandoned PS foam by molten granulation,and sorts of raw material suitable for different granulation processes,as well as the direction for utilization.The performances of polystyrene particles recovered from different granulation process were also compared.
