Abstract: A urine evaporation device comprises an outer housing; a panel assembly comprising a panel, wherein the panel assembly is contained within the outer housing, and wherein the panel comprises a liquid-absorbent substance; a fluid inlet, wherein urine contacts the panel after flowing through the fluid inlet; and an evaporator, wherein the evaporator causes evaporative ingredients in the urine to evaporate. A method of evaporating evaporative ingredients in urine comprises flowing urine into a fluid inlet of the urine evaporation device; allowing the urine to contact the panel after flowing into the fluid inlet; and causing or allowing the evaporative ingredients in the urine to evaporate.

Abstract: A portable compact toilet enclosure includes a main frame having an interior portion, a side frame, and a hood portion. The side frame is slidably coupled to the main frame and configured such that in a closed configuration of the portable compact toilet enclosure, the side frame portion is substantially disposed within the interior portion of the main frame. In an open configuration, the side frame is positioned away from the main frame such that substantial portions of the side frame portion are disposed outside of the interior portion of the main frame. The hood portion is hingedly attached to the side frame and configured such that in the closed configuration the hood portion is substantially disposed within the interior portion of the main frame, and in the open configuration is rotated in an upright position and substantially disposed outside of the interior portion of the main frame.
