Struvite (magnesium ammonium phosphate hexahydrate) is a biogenic mineral of low solubility. Its use as fertiliser has been limited to high value crops because of the additional cost of manufacture. With the advent of new interest in removing phosphorus from waste streams before land application, recovery of phosphorus asStruvite has gained new interest. Pot studies show that Struvite outperforms diammonium phosphate on a unit-for-unit basis in terms of dry matter production, P uptake, and extractable residual P. Various local waste streams are candidates for Struvite removal with little or no chemical additions using molecular templates as nucleating surfaces.
