The results of studies on purification of gas emissions (GE) with a granular sorbent based on carbonate sludge from chemical water treatment are presented. The choice of conditions for modifying carbonate sludge with a sodium silicate solution to obtain a granular sorbent has been experimentally substantiated. It is confirmed that the data obtained correspond to and complement the theoretical principles and laws of colloidal and physical chemistry, industrial ecology, which is important for the choice of engineering solutions. A technological scheme for adsorption purification with a regeneration cycle of granular sorption material based on carbonate sludge from the Naberezhnye Chelny CHPP has been developed. It was concluded that the efficiency of GE treatment increased by up to 99% when using the proposed measures. The environmental and economic indicators of the use of the resulting granular sorbent in the scheme for purifying GE from SO2 in production of sodium hydrosulfite have been calculated. The prevented environmental harm to the environment from the use of the proposed technology has been determined, as well as the cost of production of granular sorption material and the payback period.

The results of studies of the mechanical and chemical-toxicological properties of hydrocarbon-based drilled cuttings during the firing process at various temperature conditions are presented. Changes in the mineralogical composition, gross content of heavy metals, content of chloride, phosphate, sulfate ions and petroleum products, as well as the level of toxicity were studied. The indicators of the neutralization product were determined: water absorption capacity, strength, loss of strength in a water-saturated state. A technological scheme for the process of neutralizing the drilled cuttings with production of an environmentally friendly building material that can replace a part of the imported natural materials is described.

An analysis of the main anthropogenic sources of greenhouse gases entering the atmosphere was carried out, changes in emissions over the past 30 years were determined both for the Russian Federation as a whole and for a large metropolis, Moscow. The measures taken at the state and local level to implement the Decree of the President of Russia of November 4, 2020 No. 666 "On reducing greenhouse gas emissions" have been considered. The reasons why the prospects for achieving carbon neutrality may move from medium-term to long-term objectives are substantiated, as well as the possibility of scaling the experience of Moscow in implementing directions to achieve carbon neutrality while maintaining economic growth to other populated areas of the country is explored.

Based on the remote sensing data, comprehensive information is provided on mining landscapes at deposits of mineral raw materials for production of cement, crushed stone, metallurgical fluxes, and asbestos products, which are in open-pit mining in the mining regions of Russia. Using high-resolution satellite images, the amount of mining transport equipment in quarries at non-metallic mineral deposits has been determined. The volume of diesel fuel consumed by dump trucks when removing rocks from quarries has been calculated. The volume of toxic substances released into atmosphere during the operation of quarry vehicles in the being developed deposits of non-metallic minerals has been established.

The effect of contamination of ordinary black earth with platinum oxide (PtO2) on biological properties: root length and germination of radish, total number of bacteria, abundance of bacteria of the genus Azotobacter, activity of catalase and dehydrogenases have been studied. The concentrations studied were 0.01, 0.1, 1, 10 and 100 mg/kg in 10, 30 and 90 days after contamination. A stimulating effect (hormesis) of platinum oxide at a concentration of 0.01 mg/kg on the biological properties of ordinary black earth was recorded. It was found that in other cases, platinum oxide has a negative effect on the studied parameters, and exhibits the greatest toxicity after 30 days after contamination, followed by restoration of soil properties after 90 days. It was concluded that the most sensitive (highest degree of reduction) indicators to platinum oxide contamination were the total number of bacteria, germination and length of radish roots. Early diagnosis of the degree of soil contamination with platinum compounds is recommended in order to obtain a prompt assessment of the impact and prevent possible negative consequences.
