The natural, climatic and socio-economic conditions of the Arctic zone of the Russian Federation (AZRF) are considered. Factors of anthropogenic negative impact on the components of the natural environment are noted. It has been established that unauthorized municipal solid waste (MSW) dumps located in the Russian Arctic have a significant impact on the ecosystem. Contamination of soil, surface and groundwater near MSW dumps with substances of hazard classes I–IV has been recorded. It was revealed that the maximum content of pollutants in the components of the natural environment exceeds the established MPC/APC standards by 17 times.
研究考虑了俄罗斯联邦北极地区（AZRF）的自然、气候和社会经济条件。指出了人为因素对自然环境各组成部分的负面影响。已经证实，位于俄罗斯北极地区的未经许可的城市固体废物 (MSW) 倾倒场对生态系统产生了重大影响。据记录，城市固体废物堆放场附近的土壤、地表水和地下水受到 I 至 IV 类危险物质的污染。调查显示，自然环境各组成部分中污染物的最大含量超过了既定的 MPC/APC 标准的 17 倍。

To solve the issue of gas purification, a new dust collecting device with arc-shaped elements has been proposed. A feature of the device is noted, which consists in the capability of changing the flow area at its inlet by varying the number of rows of arc-shaped elements and their height, which makes it possible to select the inlet gas velocity at which the separation efficiency is maximum. The results of numerical modeling of the process of capturing solid particles from gas for various design solutions and process parameters of the unit are presented. It has been found that the high efficiency of a device with arc-shaped elements at a low pressure drop (no more than 380 Pa) is achieved by creating an arranged wave-like structure of the gas and dust flow, on the basis of which the centrifugal forces of high values arise at relatively low gas velocities at the inlet (0.25–2 m/s). A conclusion was made on the optimal design of the device, which has a height of arc-shaped elements of 250 mm and the number of their rows is 12 pcs.

The possibilities of economic justification for activities related to the treatment and disposal of sewage sludge are considered by assessing their effectiveness and efficiency. Two assessment methods are proposed: based on integral target indicators and based on a risk-based approach. A combined assessment of the effectiveness and efficiency of production and investment program activities is recommended. It is based on the main regulatory documents regulating the field of wastewater disposal. It is noted that the use of this approach will provide regulatory and regulated institutions with an effective mechanism for economic argumentation of the process costs related to the treatment of sewage sludge.

The possibility of using wastewater in the Republic of Crimea for irrigation of agricultural crops was considered, the volume of which in 2021 amounted to over 50 % of the total water intake for national economic needs from all sources. It is shown that a significant part of the wastewater after its additional purification and water treatment can be used in irrigated agriculture in the Azov Sea basin, where there are agricultural lands prepared with irrigation. It is concluded that the use of other wastewater will require reconstruction and modernization of treatment facilities, drainage systems and the creation of utilities for the accumulation of wastewater, its post-treatment for irrigation purposes and transportation to irrigation systems.

An analysis of the resource potential of macroalgae wash-outs onto the Baltic Sea coast has been performed. A critical review of the applications of polysaccharides extracted from Furcellaria lumbricalis macroalgae wastes washed ashore is presented. Optimal extraction conditions have been established to ensure maximum yield of polysaccharides. It is recommended to use alkaline hydrolysis with potassium hydroxide 0.1 M, process time is 60 minutes. Recipes of biopolymer films with the necessary physical, mechanical and antibacterial properties have been determined. It was concluded that the production of biofilms with antibacterial properties with the addition of vegetable oils is promising. Their use with application directly to the product will provide a longer shelf life without significant changes in organoleptic properties.

The influence of oil pollution of groundwater in a karst region onto the bacterial component was studied. It has been established that bacteria are present in groundwater in an amount of 103–106 cells/ml. Representatives of the genus Arthobacter, Microbacterium, Rhodococcus, Williamsia (phylum Actinobacteria), Achromobacter and Pseudomonas (phylum Proteobacteria), Bacillus and Brevibacteria (phylum Firmicutes) were revealed. The state of the microbial component of the studied groundwater was analyzed according to the scale of environmental modifications. It was concluded that, with the exception of the release of groundwater at a site 320 m away from the oil field facilities, bacteriocenoses are in a state of "anthropogenic ecological stress".

A set of issues related to the cleanup of oil and petroleum product spills in sections of the underwater crossing of the main pipeline has been considered. The special importance of timely cleanup to emergency oil and petroleum product spills was noted. Various methods for cleanup of oil and petroleum products spills on sections of main pipelines, their operating principles, technical and process features and equipment used, as well as the advantages and disadvantages of these methods have been analyzed. A diagram of an emergency situation has been constructed, and various classifications of methods for localizing the oil spills in the waters of rivers and lakes through which the main pipeline passes are presented. An optimal decision-making algorithm has been developed on the choice of method for localizing an emergency spill of oil or its processed products at an underwater crossing of a main pipeline.
