Evaluation of struvite obtained from semiconductor wastewater as a fertilizer in cultivating Chinese cabbage

► Recovered struvite from semiconductor wastewater was evaluated as fertilizer. ► The struvite showed more outstanding fertilizing effects than commercial fertilizers. ► Cu, Cd, As, Pb and Ni were observed at very low level in the vegetable tissue. ► The optimum struvite dosage for the cultivation of Chinese cabbage was 1.6 g struvite/kg soil.
