Urine Storage

Urine storage is the simplest and cheapest way to hygienise separately collected urine in order to reuse it safely in agriculture. Urine is generally sterile but contains most of the plant nutrients excreted by humans. To hygienise urine, it is stored for one up to six or more month, depending on estimated risk of cross-contamination with faeces. The sanitising effect comes from a combination of the rise of pH (due to the transformation of urea to ammonium by the naturally present enzyme urease), the raise of temperature and time.
