Systems and methods for managing waste (including liquid, solid, and mixed waste) without using a sink, worktop, or countertop disposal feature. Specific examples provide particular use in connection with an aircraft or other vehicle galley, lavatory, or any other location in which waste that requires disposal is generated. The disclosed embodiments may be installed in an initial galley or lavatory, or they may be used to retrofit an existing environment, such that an entire new disposal system or new sink footprint is not required.
