Abstract: A solvent recovering method and an apparatus for reducing the volume of expanded plastic waste are provided to reduce the solvent recovering time and to increase the recovery rate of a solvent by excluding a natural drying process for removing moisture and a process for thermal melting, friction heat, or hot blast treatment. A solvent recovering method for reducing the volume of expanded plastic waste comprises the steps of: reducing the volume by pouring a solvent into the expanded plastic waste; heating the volume reduced reactant; collecting the solvent evaporated by heating; and recovering the volume reduced plastic after discharging the solvent. The reactant is heated in an extruder type evaporator(310). The quantity of the inflow reactant and the heating time of the reactant are controlled. The extruder type evaporator has a twin screw. In particular, the heating time of the reactant is controlled by regulating the rotational speed of the twin screw.

Abstract: A method of manufacturing adsorber is provided to recycle pyrolysis residue obtained thermally decomposes waste polystyrene as a raw material of the adsorber, to reduce environment contamination problem by waste, to secure steadily the raw material of the adsorber and to save a production cost. A waste polystyrene melt is injected in a pyrolysis reactor and a styrene monomer and a pyrolysis residue are manufactured at 350 ~ 400 °C. The manufactured pyrolysis residue is heated at 900 ~ 1000 °C under an inert atmosphere and separated into a volatile component and a solid carbide. The solid carbide perform an activation reaction at 900 ~ 1000 °C by an oxidative gas.
