Yes. Sweden and EU are respectively recirculating 25% and 48% of the phosphorus from the sewage sludge production through distribution of sludge on agricultural land. Unfortunately, it doesn’t come without risks since untreated sewage sludge contains heavy metals, pathogens, and medical residues. Heavy metals, such as, cadmium are absorbed by plants and constitutes a serious health risk to humans by increasing the risk of developing bone, kidney, and heart diseases. The pathogens and medical residues effect on agriculture have in recent years being studied extensively and gained higher importance since it is suggested that medical residues possibly can increase antibiotic resistance and pathogens can reach out to drinking water areas.
