Human excreta-derived fertilizers (HEDFs) are organic made from human excreta sources such as urine and feces. HEDFs can contribute to a sustainable circular agriculture by reuse of valuable nutrients that would otherwise be discarded. However, may contain contaminants pharmaceuticals, persistent compounds, heavy metals pathogens which negatively affect plant, water soil quality. Moreover, consumer prejudice, farmer hesitance strict regulations discourage utilization HEDFs. Here, we conducted thorough review published literature explore the opportunities challenges using in agricultural systems evaluating suitability nutrient source, their typical contaminant composition, how they quality crops, soils societal impact acceptance. We found suitable nutrient-rich fertilizers, but contaminants. Processing treatments increase fertilizer reducing these contaminants, do not remove all completely. Regarding environmental impacts overall positive effects on crop yield, nutrients, plant-soil-microbe interactions plant pathogen suppression. The use reduces contamination sewage waste dumping, leaching dependent type still no increased risks with compared inorganic identified processing treatment well significantly risks. Lastly, public acceptance is possible clear outreach inform consumers farmers multi-faceted benefits safe usage after treatments. In summary, this emphasizes great potential its society, especially regions where conventional scarce, while also stressing need for adaptation specific crops.
