A waterless urinal cartridge, for waterless urinals, includes a housing and a cover. The housing includes a waste reservoir configured to hold a predetermined volume of wastewater, and a drainage aperture configured so that an amount of wastewater exceeding the predetermined volume of wastewater flows through the drainage aperture to exit the housing. The cover is coupled to the housing and includes a sealing fluid reservoir having walls that define the waste reservoir and the drainage aperture, the walls of the sealing fluid reservoir form a containment perimeter with an open bottom so as to contain a sealing fluid floating on top of the predetermined volume of wastewater, and a plurality of fluid passages direct wastewater from the fluid bowl to the sealing fluid reservoir. The waste reservoir includes a fluid flow control feature that restrains wastewater movement within the waste reservoir in response to a change in vehicle dynamics.
