Abstract: A portable restroom facility has a housing. The housing has a door opening for entering and exiting the housing. A removable waste storage container is stored within the housing for holding bodily waste. When the removable waste storage container is full or partially full, the removable waste storage container can be removed and a new clean removable waste storage container can be inserted into the housing. Thus, a waste drainage truck does not need to visit each facility and drain each portable restroom facility.
Abstract: An enclosure for a portable toilet comprises at least two sections, one of which has a door opening and a door mounted thereon. The enclosure door is moveable between a closed position and an opened position. Each enclosure section includes a first end and a second end. A tab having a hole extends from the first and a hole is formed in the second end of each enclosure section. When assembled, the first end of one section abuts the second end of the adjacent section. To ensure a substantially smooth seam or junction between the two sections, the tab extends from the inner surface of one section, across the junction between the two sections, to lie against the inner surface of the adjacent section. The tabs are aligned with the holes, and are sized such that the tab holes align with the section holes. A fastener is passed through the section hole and the tab hole to secure the two sections together. Mounting tabs are also provided at the bottom of the enclosure to secure the enclosure to the base.

Abstract: Pharmaceutically useful trace elements contained in human urine are collected by disposing a filter body containing an adsorbent for the trace elements in the gravity flow line connecting the unflushed urinal of a portable toilet to its holding tank. The portable toilet also includes a seat connected to the holding tank by a separate gravity feed line. The holding tank contains an odor reducing chemical solution for the urine and fesces. A filter body supported in the conduit between the urinal and the holding tank consists of an adsorbent for the trace constituents of the urine that it is desired to extract. Urine voided into the urinal passes through the adsorbent filter body before going to the holding tank. When the holding tank of the portable toilet is pumped clean and the deoderizing solution replaced, the filter body is removed and processed to extract the trace constituents replaced with an unsaturated filter body.
