Recycled human waste fertilizer can match mineral fertilizer yields
An international research study has found that recycled fertilizer derived from human urine and feces can achieve crop yields comparable to those of conventional mineral fertilizers.
Led by Corinna Schröder of the Network for Sustainable Sanitation Systems (NetSan), the research published in the journal Frontiers in Environmental Science analyzed 455 datasets from 201 sources across 32 countries. The study examined 13 different types of recycled fertilizers, noting that urine provides essential nutrients such as nitrogen and potassium.
While the potential for agricultural transformation is significant, researchers noted that not all products derived from human waste are equally suitable for food crop cultivation, and questions regarding the safety of these recycling processes remain.
