About 5 tons of phosphogypsum is generated per ton of phosphoric acid production, and worldwide, phosphogypsum generation is estimated to be around 100 to 280 MT per year. Globally, 15 percent is recycled as building materials, agricultural fertilizers or soil stabilization amendments and as setting controller in the manufacture of Portland cement. The rest is stored near factories, which not only has a large footprint, but also causes serious environmental contamination.
