A recycling method which enables recycling of a high-quality regenerated styrene resin. A waste styrene resin material is dissolved in an organic solvent boiling at a temperature lower than 200&deg; C. and having solubility not less than 15 wt % at room temperature to prepare a solution of the waste styrene resin material. The resulting solution is freed of volatile components on heating in vacuum to remove the organic solvent to set the amount of the residual solvent in the styrene resin to 0.4 wt % or less to recycle the resulting styrene resin as a regenerated styrene resin.
