Never human being has to face such a serious lack of phosphorus and pollutants from human activities. Nutrient recovery from wastewater is a new trend which attracts the interests of several researchers. Extraction of the nutrients, based on struvite crystal from wastewater as nutritious sources, has been assessed as an urgent solution to tackle the water pollution issue. This review focused on feature characteristics of struvite as a chemical fertilizer for plant, struvite formation process in various wastewaters, which is related to physio-chemical conditions, and potential of applying this idea into practice.By creating struvite from wastewater, a useful product can be collected for an agricultural need. Moreover, this also can be assessed as a treatment step in the wastewater treatment process which reduces the contaminants from wastewater. At present, many experiments have been conducted for several kinds of wastewaters to evaluate struvite formation potential in lab scale and pilot scale. In the future, it is essential to further develop full-scale applications to bring struvite formation technology closer to reality.
