Researchers Explore Food Safety of Recycled Human Waste as Fertilizer
A recent study has explored the potential of recycling human waste for use as a food-safe, sustainable fertilizer. The findings suggest that the risk of pharmaceuticals entering foods from human waste compost is low.
Nitrogen and phosphorous are essential nutrients for healthy plant growth in crop production. At present, however, the addition of nitrogen and phosphorous to synthetic fertilizers is unsustainable. Rich in nitrogen and phosphorous, human waste has shown potential as a novel recycled fertilizer, and it could be a possible solution that supports a circular food economy.
