| Abstract: | A compilation of generation rates and chemical compositions of potential waste streams in a typical crewed space habitat was made in connection with the waste-management aspect of NASA's Physical/Chemical Closed-Loop Life Support Program. Waste composition definitions are needed for the design of waste-processing technologies involved in closing major life support functions in future, long-duration, human space missions. Data for the constituents and chemical formulae of the following waste streams are presented and/or discussed: human urine, feces, hygiene (laundry and shower) water, cleansing agents, trash, humidity condensate, dried sweat, and trace contaminants. Data on dust generation are also presented and discussed. |
