    摘要: There is provided a processing method for effectively and promptly removing insoluble components contained in a solution of a styrene resin waste material to enable regeneration of high-quality regenerated styrene. To this end, a solution of the styrene resin waste material in an organic solvent is processed with, for example, a dehydrating agent, to remove insoluble components. The resulting clarified solution is degasified on heating in vacuum to remove the organic solvent for recycling the resulting mass as a regenerated styrene resin. The insoluble components include foreign matter, such as moisture, sludge and colorant agents. By this processing method, it becomes possible to recycle high-quality regenerated styrene.
