Objective. We performed sanitary-hygienic assessment of the use of oxygenase enzymes (Oxyzyn) and microbiological preparation EM-1 for the treatment of solid domestic waste (SDW). Materials and methods. We studied the results of the analysis of the samples of sorted, unsorted and accumulated SDW from the landfill N5, ambient air, soil, filtrate of SDW according to standardized methods. Heavy metals were determined by the atomic absorption method on a spectrophotometer of KAS-120.I type.

... The article shows that the use of probiotics is prospective for the treatment of sorted, unsorted and accumulated SDW at the landfills in Ukraine. The action of enzyme preparations in comparison with microbiological one is faster in time, and microbiological preparations is deeper as the destruction of organic substances. Conclusions. When using enzyme (Oxyzyn) and microbial preparations (EM-1) for the treatment of the unutilized part of SDW after sorting, the decomposition depth of organic substances is 1.5(Oxyzyn) -1.7(EM-1) times higher than at natural destruction. While using biopreparations, sanitary-hygienic indicators of the samples of solid waste, filtrate, atmospheric air, and soil adjacent to the landfill body are improved. The application of bioremediation technology leads to an improvement in sanitary-hygienic situation at landfills by the reduction of odours, stabilization of solid waste, improvement of the quality of landfill filtrate, and reduction of the amount of accumulated waste.
