Human Urine Utilization: A Waste Management Strategy

Waste management is the collection, transportation, processing, recycling or disposal of waste materials. The term usually relates to materials produced by human activity, and is generally undertaken to reduce their effect on health; the environment or aesthetics.Human urine can be well harnessed through proper waste management method. Waste management is also carried out on human urine to reduce the materials' effect on the environment and to recover resources from them. Human urine is liquid waste product of the body secreted by the kidneys by a process of filtration from blood and excreted through the urethra. This waste is eventually expelled from the body in a process known as urination. Most commonly the excretion of urine serves for flushing waste molecules collected from the blood by the kidneys, and for the homeostasis of the body fluids. This liquid waste product of the body is a potential source of fertilizer which is more environmental-friendly compared with chemical fertilizer if properly harnessed. The use of human urine is particular interest in the field of organic farming where fastacting fertilizers are in demand. A new project was demonstrated which showed the potentiality for developing urine-separation toilets, and that from agricultural point of view-separated urine is comparable to liquid manure. This is a unique way of managing human urine.
