摘要：

Sediments constitute one of the wastes that are generated in sewage treatment plants. The methods of their final management depend on the sewage sludge system management. One of the employed methods is Autothermal Thermophilic Aerobic Digestion (ATAD). The article presents the process of autothermal oxygen digestion of sewage sludge as a method enabling to obtain biomass, which can be used in the natural environment. In addition to the description of the theoretical basis of the discussed process. the quality of the formed sewage sludge is presented. The amount of sludge and the manner of its final utilisation were also analyzed. The results were presented on the basis of waste records kept in each of the analyzed sewage treatment plants. Sludge transfer cards in 2013-2018 were also analyzed in the sewage treatment plants where sludge undergoes the ATAD process.
