Until the 19th century, clothes were washed using old urine as detergent because of its high ammonia content11.
Some people drink their own urine, especially morning urine, which is more concentrated, as it is considered beneficial by some therapists. This is called urinotherapy or “doing amarolil”, a practice that originated in India.
Urine is a good source of nitrogen and other minerals and, when used correctly, is a completely safe fertilizer. Using urine as fertilizer saves money, fossil fuels (widely used in the production of chemical fertilizers) and water (no need to flush!). It also reduces river pollution - urine is an important source of nitrogen which contributes to the eutrophication of the river if denitrification is not used in the water treatment plant. And that's no hindsight, even space technology uses it - NASA has used urine in hydroponic growing systems!
