A review of scientific and technical literature devoted to the issues of recycling industrial waste from condensed energy systems, which is wastewater sludge from sludge reservoirs of the production facilities, containing cellulose nitrates, has been carried out. Waste sampling was carried out at one of the industry facilities. Using X-ray fluorescence analysis and IR spectroscopy, the chemical composition of the waste has been determined and its environmental hazard class was calculated. Reagents for the destruction of the main component of the waste, as well as the conditions for its recycling, were experimentally selected. Nine compositions of mineral additives based on waste sludge have been obtained, their hazard class and their chemical composition were determined, as well as their effectiveness when applied to podzolic soils.
