Step-by-Step: Urine to Fertiliser

Collection

We collect from existing toilets, avoiding waste entering the sewage system.

Nutrient recovery

Natural bacteria drive our process; converting nutrients in urine into a plant-accessible form

Safety

We filter, heat treat and concentrate our product, removing excess water and harmful pathogens. We test each batch to confirm it meets safety standards

Liquid Fertiliser

Waste is transformed into a concentrated, liquid fertiliser - suitable for a range of uses.

Impact

Attendees waste stays out of sewage, creating a circular system where nutrients in urine become a resource, not a pollutant
