| Oct 23, 2017 at 15:43 | comment | added | Andrew Neely | The kidneys filter impurities from the blood, producing urine. The body is very efficient in water management. It just uses the water to wash away biological waste in the blood supply. Build up of this waste material causes death. | |

| Dec 6, 2016 at 23:38 | comment | added | ApproachingDarknessFish | @JanDvorak Offload it into secondary bladders, store until you get thirsty, then reroute it back up to the stomach! | |
| Dec 6, 2016 at 23:31 | comment | added | John Dvorak | @ApproachingDarknessFish even if you handle the chemistry of turning urea into water + plant food, you still need a way to handle the logistics. Pure water is no use in the urinary bladder. | |
| Dec 6, 2016 at 23:24 | comment | added | ApproachingDarknessFish | @JanDvorak I imagine it be handled similarly. There are bacteria capable of fixing nutrients from atmospheric nitrogen; surely urea wouldn't be much of a challenge for them? | |
| Dec 6, 2016 at 23:23 | comment | added | ApproachingDarknessFish | @coblr No, network is contained, you see. The large intestine ins't long enough to reduce the waste to nil, so secondary conduits recirculate it through the abdomen until it's been entirely consumed. | |
| Dec 6, 2016 at 22:44 | comment | added | coblr | By "a few cycles through the C.A.N" do you mean that the crew is supposed to eat their poop? What are you considering a "cycle"? | |
| Dec 6, 2016 at 21:59 | comment | added | ApproachingDarknessFish | @HopelessN00b Good to know! I've removed the reference to worsened odor. | |

| Dec 6, 2016 at 15:05 | comment | added | Pere | 100% efficiency in water management could do it. | |
| Dec 6, 2016 at 10:03 | comment | added | John Dvorak | OK, but how do you get rid of the other body waste? | |
