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 waste receiver for receiving pharmaceutical waste material and adapted to be releasably secured to a fixed surface is disclosed. The waste receiver comprises a receiver body with a fluid absorber and a chemical composition disposed within the receiver body. The receiver body defines an opening for receiving the pharmaceutical waste material and comprises an inner surface defining a container volume in fluid communication with the opening, and an outer surface opposite the inner surface with the outer surface defining a lock passageway through the receiver body and a keyway comprising a portion of the lock passageway. The lock passageway is adapted to receive a locking assembly and the keyway is adapted to receive an engagement feature of the locking assembly to releasably secure the waste receiver to the locking assembly in a single orientation. The waste receiver also comprises a cover adapted to be coupled with the receiver body.

Provided are processes and compositions for capturing a material of interest such as a biological, chemical, or other toxic agent on or from a surface. A method includes applying a liquid polymeric coating to a surface having a material of interest deposited thereon, encapsulating the material of interest with the composition, curing or otherwise solidifying the composition to form a polymeric coating on the surface, and optionally peeling the coating from the surface. The peeling may remove a portion or all of the material of interest from the surface. Also provided are devices that may be used in the processes provided herein.

A waste disposal system with a waste receiver for receiving pharmaceutical waste material. A locking assembly is secured to a fixed surface and actuated from a locked configuration to an unlocked configuration. A lock cylinder of the locking assembly may extend forward of a front wall of a receiver body of the waste receiver to engage a locking feature of the cover in the locked configuration. A cover retention feature may prevent axial decoupling of the cover from the receiver body. An engagement feature is moved to be disengaged from the receiver body, and the receiver body is moved away from the fixed surface to disengage the locking assembly from the cover. The cover is decoupled from the cover retention feature, and coupled with the receiver body to seal the pharmaceutical waste material. The locking assembly may be removed from a lock passageway for disposal of the waste receiver.
