“…The total amount of P in the Phosphogymum made each year was estimated at 0.3-2.2 Mt [72]. Phosphogymum, in certain conditions, can be used to improve soil and reduce erosion; however, it is noteworthy for its elevated pollutant content [80]. Another by-product containing P is the slag from the ore smelting process, which is characterized by a composition containing approximately 12% P 2 O 5 .…”

Elevated phosphorus (P) levels in water sources can result in eutrophication, which in turn causes environmental pollution and adversely affects aquatic ecosystems. Additionally, there is a risk of P depletion due to intensive exploitation and utilization. Therefore, the sustainable and efficient use of P, waste reduction, and P recovery from waste sources have become urgent priorities. This article aims to provide the most current assessments of the P regeneration process and its origins within waste and wastewater. This work also evaluates P recovery, as to its mechanisms, influencing factors, and performance. Moreover, the review presents comprehensive results from pilot and full-scale applications of P recovery. Further perspectives are analyzed, including economic feasibility, potential environmental impacts, research needs, and opportunities for improving P recovery.

“…Another important branch of contaminations related to PG is the leaching behavior of the heavy metals from internal PG rather than the immobilization of heavy metal for the contaminated soils. Hassoune [82] summarized the leaching behavior of heavy metals present in PG. It was claimed that the transport of heavy metals can be divided into two categories, namely the As, Ba, Cd, Cr, and Ni were called the moderate mobility, and the Cu, Pb, Se, and Zn the low mobility.…”

Phosphogypsum (PG) is an industrial waste from the production of phosphoric acid and phosphate fertilizer. Disposal and landfill of PG pose significant environmental problems due to its hazardous components. Although many researchers have explored the possibility of PG recycling, challenges still exist before it can be high-effectively reused. In particular, a great deal of recent attention has been attracted to explore using PG as raw material to manufacture sustainable composites. The impurities movement, recycling efficiency, and environmental impacts have to be further investigated. This review article summarized the state of the art of the purification process, application areas, and the environmental impacts of PG waste. The main challenges and potential application approaches were discussed. This article is focused on reviewing the details of the PG reusing which benefits the readers on learning the knowledge from previous efforts. The main challenges of reusing PG were discussed from the chemical, physical, and materials perspectives.
