Researchers in the UK have shown that human urine could become a low-energy source of crop nutrients instead of being flushed away. Using forward osmosis, they concentrated urine into a fertilizer-rich stream while removing water efficiently. The approach could cut wastewater strain, save energy and reduce reliance on synthetic fertilizers.
