Instead of disposing of phosphogypsum in stacks, can’t the material be used for other purposes?

In 1989, EPA regulations required U.S. phosphate companies to store phosphogypsum in stacks because of slightly elevated radiation levels in the phosphogypsum. This was modified in 1992 to allow use of phosphogypsum produced in north Florida as a soil amendment.

Trade organizations like the International Fertilizer Association (IFA)  monitor where and how phosphogypsum is being used internationally.
