We investigated the possibility of preparing composite particles composed from expanded polystyrene (EPS) and inorganic solid powders by using semi-chemical recycle method with the limonene/ethylene glycol emulsion. In the experiment, magnetite and titanium dioxide were added as solid powders. As a result, it was found that composite particles coated with two solid powders were able to be prepared. Moreover, the adhesion rates of both solid powders were found to be maximum at pH=7 of the continuous phase. From these results, it was suggested that the more valuable composite materials could be prepared by the lower environmental load process.
