Urine contains water, urea and salts. Urea is produced in the liver when excess amino acids are broken down. Urea is the main waste product removed in the urine, as it is not reabsorbed in the kidney.

Urine is seen as a source of fertilizer because ... The result was then placed in a wastewater solution with a high concentration of urea. Next, the team applied an electric current.
