A Quantification Of Phosphorus Flows In The Netherlands
Phosphorus P is an essential resource for global food production. Since the introduction of phosphorus fertilizer in 1850 increasing amounts have been used in agriculture. However, the main source for fertilizer, rock phosphate, is a finite resource. Therefore, phosphorus should be used efficiently and recycling should be practised as far as.
During the transition towards sustainable use of phosphorus The EU Fertilizers Industry needs to be closely involved in P recycling To participate to developing recycling techniques To contribute defining specifications of recycled products To better integrate recycled materials in production To allow precise application techniques.

Bacterial Phosphate Metabolism And Its Application To
Phosphorus recovered from EBPR waste sludge can be used as a raw material for the fertilizer industry, if a sound recycling strategy is developed and applied. In this review, we summarize our current knowledge on phosphate metabolism in bacteria, focusing on molecular mechanisms of bacterial polyphosphate polyP accumulation.
