Nutrients such as nitrogen, phosphorus, potassium, calcium and sulfur are essential for all living organisms, in particular for plants. Thus, these nutrients are the main components of fertilizers, and so they are indispensable for the world’s food supply. Nowadays, these nutrients are only partially recycled in agro-ecosystems, since human intervention has created a linear, dispersive system.
The key response to this lack of sustainability within agriculture and waste management is to recreate a cycle of nutrients. For this reason, the Fraunhofer IGB has established a research field to develop and implement cost-efficient strategies and technologies for the integrated resource management of nutrients.
