The paper considers the main methods of processing oily mill scale and oily sludge for iron and steel production. At present, the issue of processing such waste is highly relevant for iron and steel works. The iron content allows regards them as a valuable technogenic raw material. But direct processing is complicated by the high oil content. The authors describe thermal processing variants with and without regeneration of oil products, physicochemical methods and briquetting. A desludging method with the help of Rotor Impulse Machines (RIM) is described in sufficient detail; its main advantages are presented. A very promising direction in the development of new technologies for the processing of oily sludge is the combination of physicochemical, mechanical, magnetic and other methods of desludging with the regeneration of oils.

The condition of the vegetation cover in Moscow was estimated using the NDVI vegetation index. To construct synthetic images, Landsat 5, 7, and 8 multispectral satellite images taken during the active vegetation period from 1999 to 2019 were used. Index indicators are calculated for pine forests located in protected areas, in urban parks among high-rise buildings and inside private low-rise building districts. The results showed differences in the NDVI values between these three types of birch forests, however, temporal trends show similar dynamics of changes in the physiological state of trees over the studied period.

Generalized linear models (GLM-models) are used to assess the effectiveness of environmental protection in Moscow. As the object of research, we selected projects of economic activity in natural and green areas in Moscow. The effectiveness of environmental protection work was considered as a dependent variable, and the nature of economic activity, environmental protection status, the work of social activists and environmental protection structures, as well as biotopic characteristics of the territory were considered as independent predictors. To assess the quality of the obtained models, ROC-curves were constructed. In accordance with the results obtained, the best model includes three predictors - active environmental protection work by the public and officials, and forest vegetation.
