Abstract: The article proposes a solution to two of the most urgent environmental problems in Russia. The first one is accumulation of a large amount of excessive activated sludge, which is stored on sludge maps and occupies significant territories. The second is the problem of cleaning water spaces from oil and oil products. The purpose of this study is to develop a core for cleaning of contaminants from the water surface on the example of oil sorbent. Within the framework of the work were used such research methods as experiment, generalization of the obtained data comparative analysis. For this purpose, magnetite core and magnetic sorbent were obtained in laboratory conditions, their technical characteristics were determined. According to the results of the study, a comparative analysis of the obtained data was carried out. As a result, the factors influencing the strength of magnetite nucleus were revealed. For example, magnetite core from synthetic magnetite does not need additional heat treatment. But at the same time thermal treatment is necessary for cores from coal combustion ashes As the hardener concentration increases, the strength of magnetite core increases. However, the static strength decreases with concentration above 20%. The optimal mode of heat treatment is gradual heating up to 600°C, because at this temperature the magnetite core is stable.
