The existing technologies for phosphogypsum utilization during its handling into building materials have been analyzed. Functioning equipment for joint utilization of municipal solid waste and phosphogypsum has been presented. An additional product of the installation, in addition to electrical and thermal energy, is gypsum. The waste gases from the incinerator are a heat source for roasting phosphogypsum. Fuel for the handling of phosphogypsum into gypsum is not used. A methodology for determining the specific amount of gases from a waste incinerator required for roasting phosphogypsum has been described in the article. The quantitative indicators for the reduction of polluting gases during the joint utilization of two waste types compared with operating independently waste treatment have been presented.
