Waste and Hygiene Compartment
The Waste and Hygiene Compartment currently in the US Destiny laboratory was the second toilet facility to arrive on the Station, in November 2008. The first toilet facility is in the Russian Zvezda module.
This Russian-built toilet is housed in a cubicle and separately channels liquid and solid waste. While the solid waste goes to a holding tank, the Urine Processor Assembly, which forms a major part of the Water Recovery System racks (see above), reclaims drinking water from astronauts’ urine.
