Abstract
The possibility of using phosphogypsum and off-balance sheet ores in the construction industry was considered. The results of the neutralization and reuse of technogenic waste from the phosphorous industry of phosphogypsum, which has a negative impact on the environment, are presented. The analysis of studies on the use of phosphogypsum in leading foreign countries is presented. It was found that 15% of phosphogypsum produced worldwide is reused, so it is important to explore new ways of processing phosphogypsum. Phosphogypsum widely used in agriculture as a fertilizer. The use of phosphogypsum in the road surface has not been widely used
