ECOLOGICAL ASPECTS OF PHOSPHOGYPSUM UTILIZATION TECHNOLOGIES
Results of analysis of environmental impact of existing phosphogypsum utilization technologies during the processing it in construction mixes compared with the proposed technology are presented in the paper. It is shown that widely used technologies for phosphogypsum utilization in the world are very energy-intensive, and the cost of wastewater treatment is 2,5 times greater than the costs of one unit production. Also, the process is accompanied by significant emissions of greenhouse gases. Environmental and energy advantages of the technology, namely the lack of wastewater, as well as GHG emissions reduction to 28 times are presented.
