Recycling and/or upcycling of agricultural byproducts containing valuable nutrients back into agricultural systems as bio-based fertilizers can improve the circularity and sustainability of food production. However, in some instances, there may be negative environmental consequences or safety concerns that need to be carefully considered. One of the most common issues regarding the use of bio-based fertilizers, in particular livestock manure, is the over concentration of nutrients in regions with intensive production leading to losses of reactive nitrogen and phosphorus into the environment. This can have negative impacts on air and water quality as well as contribute to climate change. In addition, some bio-based fertilizers may contain heavy metals, pathogens, antibiotics, and other contaminants that can pose a health risk to humans, animals, crops and the ecosystem. Recognizing and managing these risks is necessary to fully integrate these products back into production systems, thereby enhancing the circularity of agriculture.
