“…Lime sludges usually contain more than 70% calcium carbonate. Quite acceptable methods are the use of sediments in the natural environment to be applied to the soil to reduce acidity (Cheng et al, 2014), or in the man-made environment to improve wastewater treatment (Hua et al, 2019). In (Hua et al, 2019), a water treatment method of reusing the upper clarified part of lime sludge to simultaneously remove COD, nitrogen, and phosphorus was investigated.…”

The work highlights the dangers caused by industrial waste that is stored for a long time in repositories. The largest waste storage site of the chemical industry in the Luhansk region is described in detail. More than 100 types of waste are stored at the landfill. PJSC “Severodonetsky Azot” is considered the owner of the landfill, but nearby are the waste storage facilities of other largest enterprises of the region: “Rubizhansky Krasytel”, Scientific and In-dustrial Association “Zarya”, Lysychansk Plant of Rubber and Technical Products, and Scientific and Industrial Association “Skloplastik”. The impact of landfill waste on the environment is determined not only by the dura-tion of waste storage and the technical imperfection of the repository but also by the geological structure of the location region. The most dangerous impact of storage is on the state of water bodies in the region and on underground sources of drinking water supply. This fact is evidenced by long-term observations of water quality in water supply sources given in the work. Ways of processing certain types of waste contained in the landfill are proposed. The general characteristics of solid industrial waste processing methods are given, a description of the possible utilization of certain types of industrial waste into mar-ketable products is given.

We are happy to present the multi-authored monograph “Modern forms of development of resource-saving technologies for minerals mining and pro-cessing”. The monograph discusses actual and promising resource-saving technologies for exploration, development, extraction and processing of ore and non-metallic minerals. Much attention is paid to technical means and technological complex-es that support these processes. The monograp analyzes new approaches to the formation of a resource-saving model of a mining enterprise with due regard to mining safety. In addition, the monograph analyzes principles of organizing resource-saving production, and sources of resource losses in mining. The critical analysis has enabled working out a package of measures aimed at forming a rational model of a resource-saving mining enterprise. The monograph also presents a model of a mining enterprise operating in conditions of resource saving and rational envi-ronmental management. The monograph is intended for a wide range of scientists, specialists involved in analyzing development of mining complexes in regions, as well as master’s and doctoral students of relevant specialties of higher educational institutions.
