Abstract: A system for gasifying styrofoam and liquefying the resulting gas to a liquid styrofoam. This system is particularly useful for disposition of the styrofoam onto which non-meltable substances adhere. The system includes a pulverizing mechanism for pulverizing a lump of styrofoam and a melting vessel for melting the pulverized styrofoam.
