Liquid gold: The potential and risks of turning human urine into sustainable fertilizer

A new research review led by Griffith University suggests using human urine as a fertilizer could significantly boost sustainable agriculture—but key health risks and knowledge gaps must be addressed before it could be widely adopted. The review, led by a multi-disciplinary research team from Griffith, analyzed 35 global studies examining microbial risks associated with urine-derived fertilizers (UDF). The results are published in Water Reuse.
