Urine Collection

Reduce wastewater, protect underwater ecosystems, and gain free liquid fertiliser.

Creates Gold-Standard Fertilizer: Human urine is packed with nitrogen, phosphorus, and potassium—the exact “NPK” foundation of commercial fertilizers. Diluted with water, it acts as a free, highly effective liquid plant food.

Removes Toilet Odour: Foul bathroom smells happen when urine and faeces mix, creating anaerobic sludge and ammonia gas. By keeping them separate, composting toilets or dry collection bins stay remarkably fresh and dry.

Protects Marine Ecosystems from Algae Blooms: Traditional sewage treatment plants struggle to remove phosphorus and nitrogen from wastewater. When these nutrients enter rivers and oceans, they trigger toxic algae blooms that suffocate fish; collecting urine keeps them out of the water cycle.

Reduces Wastewater Treatment Costs: Urine makes up less than 1% of total domestic wastewater volume but carries over 75% of the nitrogen and 50% of the phosphorus. Collecting it at the source slashes the energy and chemical costs needed to clean regional wastewater.

Saves Flush Water: Specially designed urine-diversion toilets use very little water (or none at all) to flush the front bowl. Because we pee much more often than we poop, this single adjustment drastically shrinks a household’s daily water footprint.
