Rethinking Urine

Urine is a resource, not a waste. It’s time to change the way we treat it.

Our “liquid gold” is an abundant source of sustainable fertilizer, but we currently flush it into sewers where it causes nutrient pollution that is costing municipalities billions to remediate. By collecting and recycling urine into fertilizer, we can more affordably protect the aquatic environment while replenishing the soils that support us.

Urine Diversion is the practice of keeping human urine separate from the rest of the wastewater stream. Collected urine can be used as fertilizer, either around the home or on a nearby farm.
