METHODS OF PROCESSING TECHNOGENIC WASTE OF PHOSPHOGYPSUM JSC "GOMEL CHEMICAL PLANT"

Abstract

In the Republic of Belarus, the ecological problem of rational processing of technogenic phosphogypsum of JSC "Gomel Chemical Plant" is considered urgent, which occupy the third place in terms of waste generation after JSC "Belaruskali" (salt halite waste and clay-salt sludge). Multi-tonnage waste is burdensome material for the region and the general ecological situation of the republic, affecting ecosystems and exacerbating the social tension of nearby settlements.  The purpose of this study was to analyze the existing information regarding phosphogypsum: chemical composition, storage conditions, possible areas of use and methods of processing this waste, as well as environmental risks, radioactive hazards identified in connection with its formation, its interaction with other ecosystems and its negative impact on them. Some ways of solving existing problems are given.

Promising areas of practical use of phosphogypsum in its original or processed form (extraction of REE, in road construction, soil reclamation, in the construction sector) are considered, the importance of processing phosphogypsum to reduce the anthropogenic load and obtain target products in demand, as well as the importance of minimizing the negative effects of waste accumulation and storage on all components of the environment is analyzed.
