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.

Abstract: Improved control for the separation of waste materials, or materials having waste components, is provided by the injection of air, or other gas bubbles, into a water-filled tank while simultaneously depositing the waste containing material to be separated onto the top of the water. This method is especially useful where both portions of some or all of the materials to be separated from each other have specific gravities greater than that of pure water. The rapidly rising air bubbles provide turbulence and buoyancy to materials that are slightly heavier than water, such as water-soaked organic products, but do not prevent heavier materials, such as sand and metals from sinking. An apparatus is described which allows for the removal of both the floating and sinking fractions from the floatation tank.

Abstract: The present invention features a portable waste disposal unit designed to receive expanded polystyrene or similar polymeric waste. Waste is loaded into a waste reception chamber via a loading door. Once the loading door is closed and locked, a mechanical ram forces the waste charge downward into a removable tank containing a layer of a solvent such as perchloroethylene and an upper layer of water. The waste is dissolved in the solvent and stored until the tank is either removed or drained and the contents shipped to an appropriate waste recovery facility. The small size of the portable waste disposal unit makes it ideal for location near the source of the waste to be recycled. Significant compacting of wastes such as expanded polystyrene may be realized by dissolving the waste in a solvent such as perchloroethylene. In addition, the first step of a recycling process is effectively accomplished within the inventive unit.
