urine recycling

Human urine is actually sterile (unlike feces, urine is bacteria-free). Far from being a dirty body-waste, fresh, normal urine is actually sterile and a mixture of some of the most vital and medically important substances known to man. It contains minute amounts of proteins made by the body, including medically important ones such as growth hormone and insulin. It is estimated there is a $500-million USD-a-year market for these kinds of ingredients. Whilst the idea of recycling urine is not new, it needs thousands and thousands of liters to commercially produce products.
