  • Publication number: 20140235917
    Abstract: A device for disposing unused pharmaceuticals including a container having sealing means, a superabsorbent polymer arranged in the container in a loose orientation, a deterrent compound, and optionally a dye. The device is adapted so that after pharmaceuticals and a fluid substance are added to the container, and the container is sealed, the container can be agitated (e.g., shaken) to enable the superabsorbent polymer to absorb the fluid and congeal in order to nearly instantaneously form a gel structure, which completely or nearly completely envelops the pharmaceuticals in the container. The deterrent compound can break down and/or denature the pharmaceuticals enveloped in the gel structure. The container may then be disposed of in a conventional household garbage container. The dye provides a visual warning that the pharmaceuticals should not be consumed and the repellant compound provides an unpleasant flavor and/or smell which deters ingestion of the pharmaceuticals.

    Abstract: A new covered landfill or remediated waste containment cell having an excavated bottom surface, lined with a watertight liner and a leak detection system for determining whether or not leakage has occurred, either from the top, or from the bottom. The cover over the landfill containment cell substantially prevents rainwater from coming in the top, and the liner stops water from erupting up from the bottom. This containment cell allows a method of storing waste in an essentially non-contaminating manner, thereby providing an environmentally sound procedure and apparatus for storing toxic wastes. This containment cell is particularly suitable for remediating old leaking landfill sites within a short distance of the old site.

  • Patent number: 6002063
    Abstract: Injection of slurried wastes is carried out within deeply buried strata. Appropriate target strata are identified in terms of sufficient porosity and permeability, and overburden that includes permeable and impermeable strata. Slurry is injected at sufficient pressure to establish fracturing within the target strata. The injection pressures and the resulting waste pod are monitored by a suite of monitoring procedures, including bottomhole pressure and surface uplift. The injection is carried out in a series of injection episodes separated by interinjection episodes. Apparatus for preparing and injection the slurry include a mixing chamber, a partly encased well and a bottomhole pressure gauge. Process monitoring apparatus controls the operation of the system.

  • Patent number: 5926772
    Abstract: The present invention provides a composition and process for disposal of radioactive, hazardous and mixed wastes. The present invention preferably includes a process for multibarrier encapsulation of radioactive, hazardous and mixed wastes by combining substantially simultaneously dry waste powder, a non-biodegradable thermoplastic polymer and an anhydrous additive in an extruder to form a homogenous molten matrix. The molten matrix may be directed in a "clean" polyethylene liner, allowed to cool, thus forming a monolithic waste form which provides a multibarrier to the dispersion of wastes into the environment.

  • Patent number: 5906572
    Abstract: A device for collection and containment of spilled or leaked liquid hydrocarbons absorbs pollutants that come in contact. The absorbed material is solidified-within the pillow into a rubber-like mass. An impermeable layer-of material may be utilized in forming the bottom layer of the outer envelope of the device to retain accumulated hydrocarbons-within the pillow while further allowing the contaminants to disperse throughout the device for absorption and solidification. The impermeable layer prevents spilled or leaked hydrocarbons from contaminating the surface below the device. The consolidated mass is easily retrieved and handled for disposal. A variety of options may be utilized in disposing of the spent device, including recycling the rubber-like mass as a component of tar-like materials, such as asphalt. The solidified hydrocarbons will not leech when exposed to pressure limits used to determine landfill suitability.
