A local neutralizing device for strong acid or strong base accidental environmental contamination is provided in the form of a compressed canister with a content distribution means which is portable and target control specific by a user to dispense a weak base to a strong acid accident location to neutralize the strong acid, or alternatively to dispense a weak acid to a strong base accident location to neutralize the strong base, either alternative intended to reduce, contain, neutralize and assist in the remediation of the accidental spill.

A PFAS detoxification system 1 includes a concentrator 11 configured to concentrate a waste liquid containing PFAS, discharged from a semiconductor manufacturing apparatus 100; a sulfuric acid processing tub 12 configured to decompose and evaporate a concentrated liquid concentrated by the concentrator 11 with a liquid containing concentrated sulfuric acid; and a cooling apparatus 13 configured to liquefy and collect a gas evaporated by the sulfuric acid processing tub 12.

A method and system for in-basin neutralization is provided. More specifically, neutralizer is added to a basin in excess of an amount of neutralizer suitable to neutralize a treatment solution in a reservoir in fluid communication with the basin. A first portion of the treatment solution is added to the basin and is contacted with the first portion of the treatment solution to form a secondary solution. The first portion of the treatment solution is neutralized with the neutralizer. A first portion of the secondary solution is removed from the basin. A second portion of the treatment solution is added to the basin. The second portion of the treatment solution is contacted with a second portion of the secondary solution remaining the basin to form a tertiary solution. The second portion of the treatment solution is neutralized with neutralizer in the second portion of the secondary solution.

A medication disposal apparatus and method of use with multiple stages of conversion operable to render a controlled substance useless.

The invention relates to a system for asbestos neutralization, that comprises a neutralization unit comprising, in an atmospheric containment: a module for sorting of asbestos waste, an asbestos waste grinder, which reduces the size of the asbestos waste to a dimension ranging from one-tenth of a millimeter to one millimeter, a concentrated sulfuric acid tank, a vat containing a hot diluted acid solution, for which temperature is between 70 C. and 100 C., in which grinded asbestos waste containing asbestos is dipped, said solution neutralizing asbestos contained in the grinded asbestos waste, a filtration unit to separate, at the end of the neutralization reaction, a solid inert waste from a liquid phase of the diluted acid solution, a regeneration unit for the diluted acid solution, which adjusts the hydrogen potential of the extracted liquid phase by adding concentrated sulfuric acid from the tank, and means for transferring the regenerated solution into the vat.

The invention relates to a system for neutralizing asbestos, said system comprising a mobile neutralization unit (200) comprising: an asbestos waste sorting module (225), an asbestos grinder (255) and a hot acid bath (250) for rendering asbestos inert. Preferably, the asbestos waste sorting module comprises: a window with glove boxes; and a conveyor for transporting the asbestos waste in front of the window. In embodiments, the system comprises a means for containing the atmosphere within the mobile neutralization unit and/or the hot acid bath (250) of the mobile neutralization unit (200) comprises sulfuric acid.

A device for destroying a chemical agent is described. The device includes a self-contained, portable pressure vessel which is dimensioned to accommodate an artillery shell, and a heat-generating component within the pressure vessel. The heat-generating component is capable of providing a pyrolytic, exothermic reaction capable of destroying the chemical agent and artillery shell. A process for destroying a chemical agent which includes placing a chemical artillery shell within the pressure vessel, securing the pressure vessel closed, and igniting the heat-generating component inside the pressure vessel to generate a pyrolytic, exothermic reaction capable of destroying the chemical agent and artillery shell is also described.

A medication disposal apparatus includes a collection chamber to receive a medication having an active agent. The collection chamber includes a receiver having a one-way opening. The one-way opening receives the medication in the collection chamber and to impede the medication from exiting the collection chamber through the receiver. The collection chamber includes a first converter to receive the medication and/or convert the medication into a plurality of particles. The first converter is housed in the collection chamber and/or may receive the medication from the collection chamber. The first converter has a grinder with a plurality of rollers operable to convert the medication into the plurality of particles. The first converter includes a motor powered by a power source. The apparatus includes a reservoir fastened to the collection chamber and apparatus includes a second converter.

The asbestos waste neutralization device (10) comprises: an acid tank (23), a vat (16) containing a diluted acid solution, in which waste containing asbestos is dipped, with this solution neutralizing the asbestos waste, a filtration unit (21) to separate, at the end of the neutralization reaction, the solid inert waste from the liquid phase of the acid solution, a regeneration unit (22) for the attacking acid solution, which adjusts the hydrogen potential of the extracted liquid phase by adding concentrated acid contained in the acid reservoir, and means for transferring the regenerated solution into the vat.

Portable wet drilling waste treatment. In one example embodiment, a method for portable wet drilling waste treatment may include transporting a transportable frame, maneuvering an open end of a waste conduit, vacuuming air and the wet drilling waste, using a motor-driven vacuum, into the open end of the waste conduit, through the waste conduit, and into a cyclonic separator, separating the wet drilling waste from the air using the cyclonic separator, using a waste auger to transport the wet drilling waste, using a treatment material auger to transport a treatment material, operating the waste auger and the treatment material auger at coordinated rates to transport an effective ratio of the wet drilling waste to the treatment material, using a mixing auger to simultaneously transport the wet drilling waste and the treatment material, and operating the mixing auger at an effective rate resulting in a solidified treated material.
