Recycling phosphate without use of auxiliary substance

Phosphate is an essential nutrient for growing crops and it is extracted in mines. The supply phosphate from mines is finite. It is also possible to recycle the mineral from sewage sludge, but not without using an auxiliary substance that is harmful to the environment. Together with colleagues at Wetsus, environmental technologists at Wageningen UR are developing a method to recycle phosphate that does not require an auxiliary substance.

They discovered a bacterium in sewage sludge that sometimes produce phosphate granules. Based on this discovery, they are now developing an environmentally friendly method to win phosphate from sewage sludge. This is how Wageningen UR contributes to improving the quality of life.
