== Sanitation system ==
The techiques techniques described in this section, according to the elements above make up entire sanitation systems. The following is an example of this. reading the icons from the left to the right we have a [[Dry urine diversion toilet]] connecting to [[Oil drums and containers]] system, where the feces are taken away via a [[Cartage system]] to be broken down via [[Co-composting]] and then finally be used through [[Compost as soil conditioner]] and the [[Human urine as fertiliser]].
