Wastes are placed in a container, and the container is closed by a lid having a port sealed by a disc. A cutting tool having a hollow drive stem pierces the disc. A grout slurry is fed through the stem so as to discharge into the container and embed the wastes in the grout when set. The wastes may be contained in a crate in the container, and may also take the form of a glove box which itself contains waste objects.

The present invention adds carbonates or chlorides of alkaline earth metals to the radioactive wastes containing sodium sulfate and subjects sulfate group in the radioactive wastes to reduction treatment, thereby converts the sulfate group into sulfides of alkaline earth metals which are chemically stable substances while suppressing SOx generation, and solidifies the radioactive wastes stably for an extended period of time by applying to the converted radioactive wastes solidifying treatment.

Toxic wastes and other contaminants are removed from soil which is fed through a passage in an agitating means into a retort (10, 110) where the soil is agitated and brought into contact with the retort walls (11, 111, 111A) (at a temperature preferably above 500.degree. C.) to cause the toxic wastes or contaminates to be desorbed. The "off-gases" from the soil may be mixed with air/fuel in a combustion chamber (31, 131), to heat the retort; may be burnt in a secondary burner (40) to preheat and...

Water to be utilized is reacted with soda ash and lime to produce a less corrosive and foulant water. Reaction sludges are fed to a desulfurization unit, where SO.sub.x, NO.sub.x and CO.sub.2 abatement occurs; other industrial waste sludges and/or waters and/or gases can also be utilized in such connection. FIG. 1 is one of the possible process schemes of the present invention.

A process for stabilizing organics-containing waste materials and recovering metals therefrom, and a waste glass product made according to the process. Vitrification of wastes such as organic ion exchange resins, electronic components and the like can be accomplished by mixing at least one transition metal oxide with the wastes, and, if needed, glass formers to compensate for a shortage of silicates or other glass formers in the wastes. The transition metal oxide increases the rate of oxidation ...

The system (10) for collecting and disposing of medical sharps and other medical wastes includes a housing (11) and its telescopic cover (9) which are fabricated of biodegradable and combustible material such as natural cellulose, non-natural cellulose, and other materials and an absorbent biodegradable and combustible absorption package (30) or insert (35) can be placed in the bottom of the holding chamber (12) for absorbing any liquids emitted from the sharps and other medical wastes, and for ...

A process for the recycling of organic waste including the steps of passing a waste into a first sealed container, introducing an inert gas into the interior of the first sealed container so as to displace oxygen from within the container, heating the interior of the first sealed container to a temperature of between 1,000.degree. and 2,700.degree. F. so as to form a heated gas within the sealed container, filtering the heated gas so as to remove sulfur and chlorine byproducts of the heated gas,...

The system (10) for collecting and disposing of medical sharps such as personal use insulin syringes and other medical wastes includes a housing (11) and its telescopic cover (9) which are fabricated of biodegradable and combustible material such as natural cellulose, non-natural cellulose, and other materials and an absorbent biodegradable and combustible absorption package (30) or insert (35) can be placed in the bottom of the holding chamber (12) for absorbing any liquids emitted from the sha...

A container for disposing of hazardous wastes including an inner receptacle adapted to receive and contain the hazardous wastes or etiological agents and an impact resistent outer container with the inner receptacle disposed within the outer container. The container further includes a fluid barrier located between the inner receptacle and the outer container. The fluid barrier acts as an intermediate containment to minimize fluid from passing from the inner receptacle to the outer container in t...

A method and apparatus for anaerobic digestion of fish wastes and production of useful by-products including fertilizer and biogas. The method includes grinding up the fish wastes and adding liquid to create a suspension of up to 25% solids; optionally adding lipase to break down the fish oil; and anaerobically digesting the fish suspension over a period of approximately 20 days at a temperature in the range of 35.degree.-55.degree. C. with mixing provided by recirculation or other means. After ...
