Seems like these systems assume only human urine will go into these storage systems. But in reality, people tend to flush more than just fecal matter, urine, and water down the drain. In order to clean the toilet bowl, people will use highly poisonous cleaning solutions. How will these cleaning solutions mixed with the stored urine affect its usage as a fertilizer? Even if it is eventually dehydrated, wouldn’t some of the cleaning solution still be present? What happens if you send other types of fluid down the “urine only” toilet or system (ie, blood, vomit)? People will even flush drugs, dead pet fish, alcohol and other non-human waste products down the drain. In theory, it sounds like a great way to reduce our carbon footprint. But if they are designing the system on the assumption that people are smart and will only use it as intended then it might actually cause the opposite effect.
