Reasons for urine source separation and treatment
Learn about the harmful over-accumulation of reactive nitrogen into the environment and how human excreta contributes to this.
Source separation of urine is the basis for proper urine stabilization. When urine is properly stabilized, it maintains its valuable nutrients and the hazardous release of reactive nitrogen into the environment is avoided. Uncontrolled discharge of reactive nitrogen into groundwater, open water and the atmosphere is reduced. This decreases the potential of future environmental and human health hazards. Additionally, the recovery of nutrients from source-separated urine allows the closure of the nutrient loop. By using recovered nutrients as fertilizer, energy intensive fertilizer production and transport can be minimized.
Distillation or evaporation follows urine stabilization in order to reduce the transport volume of the urine fertilizer.
