Looking Beyond Struvite for P-Recovery

) and could potentially be used asa slow-release fertilizer. If the economic and life cycle costs aretaken into account, however, it becomes clear that phosphaterecovery as struvite is likely not the best approach, for thefollowing reasons: (1) production of P-mineral with a highcontent of struvite from real wastewater is a dicult and costlyprocess; and (2) struvite is not superior to other phosphate-based compounds in fertilization eciency, nor is it an exclusiveform of raw materials favored by the fertilizer industry.In literature and practice, struvite precipitation is usuallyperformed under alkaline conditions, which are created bydosing alkalinity or CO
