System for solidification of pharmaceutical waste
The invention includes a system for solidification of pharmaceutical wastes. The system may be for use in connection with a container serving as the medication bottle. The system includes an absorbent composition including a plurality of surface cross-linked superabsorbent particles. Additionally, a soluble packet may be included so that the absorbent composition is released upon dissolution of the packet and medication is rendered unavailable. The invention also includes a method of solidifying pharmaceutical waste.
1. A method for solidification, the method comprising:
introducing an aqueous liquid into a container containing pharmaceutical waste and a dissolvable micro-packet, wherein the dissolvable micro-packet comprises a dissolvable portion and a non-dissolvable portion,
wherein the dissolvable micro-packet contains an absorbent composition, the absorbent composition comprising about 1.0 g or less of a surface crosslinked superabsorbent polymer and about 0.1 g of denatonium benzoate or denatonium saccharide configured to make the absorbent composition and the pharmaceutical waste unsuitable for consumption when solidified,
wherein the dissolvable micro-packet further contains a disinfecting agent,
wherein the dissolvable micro-packet is secured to an inner bottom surface of the container by an adhesive,
wherein the surface crosslinked superabsorbent polymer is a polymer FDA approved for use as an indirect food additive,
wherein the container is a prescription medication bottle,
wherein the dissolvable micro-packet has a thickness between 1 mm and 1.5 mm, and
wherein an amount of the aqueous liquid introduced into the container is sufficient to at least partially dissolve the dissolvable micro-packet;
at least partially dissolving the dissolvable micro-packet in the aqueous liquid such that the absorbent composition is exposed to the aqueous liquid; and
solidifying the absorbent composition and the aqueous liquid within about 2.5 minutes after the absorbent composition is exposed to the aqueous liquid, the absorbent composition and aqueous liquid remaining solidified for at least five days after initial solidification.
2. The method of claim 1 wherein the surface crosslinked superabsorbent polymer is a swellable, insoluble, surface crosslinked polymer.
3. The method of claim 1 wherein the absorbent composition includes a denaturing agent.
4. The method of claim 1 , wherein the surface crosslinked superabsorbent polymer maintains permeability while the absorbent composition and the pharmaceutical waste are solidified, such that gel-block is prevented.
5. The method of claim 1 , wherein the absorbent composition and the pharmaceutical waste are solidified without about 2.5 minutes in the absence of agitation of the container.
6. The method of claim 1 , wherein the disinfecting agent comprises a chlorine agent.
