Seawater can accelerate the transition towards circular economy and make phosphorus recovery more efficient. Phosphorus (P) from rock phosphate is a limited resource, and increasing demand will make the phosphorus situation challenging in the coming century. With the transformation to circular economy in the wastewater industry, we wish to make recovery of P more efficient. In wastewater utilities with biological P removal there is a great potential to crystallize P as struvite. This process needs an addition of magnesium, and an alternative to commercial magnesium salts is seawater, which is both cheap and unlimited.
