Canadian company Ostara has big ideas for closing the usage cycle and reducing eutrophication the phosphate industry. By introducing a wastewater-sourced struvite phosphate fertiliser, which has a low water solubility, one of the most damaging environmental problems associated with fertiliser application could be ameliorated.
