A peer-reviewed paper by scientists in Europe published in the journal Frontiers in Environmental Science found that fertiliser made from human faeces and urine is safe to use
Nutrient-rich human fertiliser has its benefits, as long as there is no risk that harmful microbes could end up in crops, which the University of Hohenheim, Stuttgart has confirmed is not the case.
As farmers in Europe and across the world grapple with increases in the cost of fertilizers, researchers suggest a solution may be closer to home in what people flush down the toilet.
