Apparatus for extracting proteins from urine

A flushless portable toilet incorporating means for extracting commercially useful constituents from the urine voided into the toilet comprising:

• a unitary enclosed shelter having a door;
• a urinal supported within said shelter;
• a holding tank supported in said shelter at a level below the urinal, said holding tank being adapted to retain a deoderizing chemical solution for the urine;
• a conduit connecting the urinal to the holding tank;
• container means formed as part of the conduit intermediate the urinal and the holding tank for retaining a filter body;
• and a filter body removably disposed in the container means, the filter body constituting an adsorbent for at least certain trace constituents of urine allowing urine voided into the urinal to pass through the conduit and the filter body to the holding tank under the force of gravity, the urine thereby contacting the adsorbent so that at least a portion of the trace constituents adhere to the adsorbent from which they may be extracted upon removal of the filter body from said container means.
