Phosphogypsum: Environmental Repercussions and Incentives

One prominent by-product of the generation of phosphoric acid, phosphogypsum, is recoverable. However, phosphate, fluoride, and heavy metals are among the contaminants found in phosphogypsum that can impair performance and pollute the environment.Crushed blast furnace slag, electrolytic manganese wastes, and inorganic cement-like substances can all be used with phosphogypsum. Surface modifiers, curing agents, and polymers are some instances of additives.Phosphogypsum (PG) is an industrial by-product of the wet process used to produce phosphoric acid from natural phosphate rock. An estimated 100–280 Mt of PG are produced annually worldwide, with 5 tonnes produced for every tonne of phosphoric acid. The majority of this by-product is dumped in big stockpiles without any sort of treatment. These are typically found near phosphoric acid facilities along the coast, where they take up a lot of land and seriously harm the ecology. In order to reduce environmental hazards, this review paper examines appropriate handling,retention, and clearance techniques.Moreover, creative reuse applications are researched, like adding phosphogypsum to building supplies like concrete, plasterboard, and cement as well as using it in farming as a supplement to the soil or for reclamation of agricultural land
