Based on the vibration method of disintegration, new crushing and grinding machines have been created, in which the intra-layer dynamic destruction of the material is realized by a combined vibration-pulse compression with a shift. The design and technological features of vibration crushers are considered, as well as the experience of their industrial use in the processing of various types of raw materials, including industrial waste. It is shown that vibration disintegration provides efficient processing of production wastes and higher technical and economic indicators in comparison with traditional technologies. The sufficiently long operating experience of the created vibration machines proves a real reduction in energy consumption by up to 30%, especially for highly hard materials.

The results of studies of the use of vibration disintegration technology to obtain a mineral feed additive based on schungite are considered. It is shown that the vibration impact on the processed material provides the product of the desired fractional composition and grain shape. It has been established that the "Mustala" feed additive obtained by the vibration method on the basis of schungite is an effective mycotoxin sorbent and provides an increase in zootechnical indicators of poultry rearing.

The problem of the formation and processing of waste in the production of crushing stone for road construction is considered. An integrated approach is proposed, which implies both a reduction in the amount of waste generated and its subsequent processing to obtain products in demand on the market. The technologies based on the use of vibration equipment and allowing to obtain qualified products from crushing screenings are described: cubical crushed aggregates, high-quality fractionated artificial sand and vibro pressed products based on it. The possible options for recycling the dust-like component of the waste with the production of lightweight aggregate for concrete and mineral wool are given. An estimate of the predicted environmental effect of preventing the disposal of waste from the production of crushing stone for road construction, subject to the application of the proposed technologies, is given.

Using the example of a forecast developed for St. Petersburg, an analysis was made of typical problems and nuances for Russian megalopolises that should be taken into account when predicting the volume of municipal solid waste (MSW). A statistical method is described that is recommended for a long-term forecast of the generation of MSW in the Russian Federation. The results of waste generation forecasting in St. Petersburg until 2030 are given. Recommendations are given on improving statistical accounting in the field of municipal solid waste management.

The article presents the results of an industrial test of a new technique for wastewater disinfection that combines ultrasonic and ultraviolet methods at the final stage of water purification in order to destroy pathogenic microorganisms, and thereby prevent the spread of infectious diseases. The new method was developed and patented by the authors; it has been tested at one of the most advanced water utilities in Russia, SUE “Vodokanal of St. Petersburg”. The combined ultraviolet and ultrasonic wastewater treatment proved to be effective.

The results of tests of secondary construction materials derived from man-made materials are presented. The granulometric and chemical compositions of secondary products from technogenic raw materials are investigated. The analysis of local natural and man-made raw materials base of the Chechen Republic. The possibilities of using local natural raw materials (crushed stone from gravel, natural sand, gravel, gypsum, cement, etc.) in the technology of building composite materials are shown. The suitability and efficiency of the use of technogenic raw materials in concrete and mortar technology, justified by the complex economic and environmental effect of its use in the practice of building materials science, have been experimentally proved. It has been established that with the introduction of advanced innovations in the field of concrete science it is possible to produce competitive products that are not inferior to foreign analogues.

Presents the results of research on the development of a method for joint utilization of polystyrene foam and brick waste with obtaining a polymer composite material for the production of wall cladding products. This method consists in grinding the waste polystyrene foam with their subsequent dissolution in carbon tetrachloride and cold mixing the resulting solution with a crushed brick. This method reduces the energy intensity of production, eliminates thermal decomposition of the polymer binder during processing and makes it possible to jointly dispose of two types of large-tonnage waste. Products that can be obtained from the developed material, according to the values of frost resistance and water absorption, meet the requirements for products for external facing of walls and sole plates of facades.

The results of the study of the efficiency of heat treatment of samples of glauconite are presented. Estimated ability of the sorbent to water absorption and retention of petroleum products. It was established by the method of differential scanning calorimetry that thermally activated glauconite samples are practically not saturated with water vapor. Oil capacity decreases after heat treatment of glauconite at 600°C and increases at 1000°C compared with the original sample, which is explained by various structural changes.

A method for assessing the risk of air pollution by suspended particles smaller than ten micrometers (PM10) on the street road network (SRN) of the large city is presented. It includes an assessment of the intensity of the release and distribution in air of PM10, the sources of which are exhaust gases from vehicles with diesel engines, tire wear, and road surface wear. An assessment is made of the chronic and carcinogenic risk to public health from exposure to PM10 in the air in a roadside area. Substantiated measures to reduce the risk to public health from PM10 air pollution in the SRN.

The paper considers the issue of changing the quality of water in the Voronezh reservoir due to its contamination with cyanotoxins. The authors give a forecast of the ecological and sanitary state of the aquatic environment and propose preventive environmental measures.

The main sources of environmental hazards at various stages of the product life cycle are described, and ways are offered to remedy the current situation by: creating uniform rules for ensuring the environmental safety of products, taking into account its specific characteristics; the development of standards, the technical requirements of which would protect the environment from the harmful effects of products at all stages of its life cycle; the formation of a new category of standardization – regional standards that ensure the environmental safety of technical regulation, taking into account the particularities of the regions.

The monitoring studies of the ecological state of soils of agricultural lands in the area of operation of the mining and smelting enterprise OJSC MMC Pechenganikel, located in the North-Western part of the Kola Peninsula, are presented. Planning of the survey (creation of a digital cartographic base) was carried out in a GIS environment using raster archive data and Earth remote sensing data. The accuracy of soil sampling within the boundaries of the selected elementary areas and contours was ensured by the use of GPS navigators. A significant excess of the APC content of Cu, Ni, As in the studied samples was established. Based on the survey results, cartograms were compiled using the GIS software package.

The soil contamination with heavy metals (HM) Cu, Zn, Fe, Mn, Cd and Pb was studied in the zone of influence of the Beloretsk Metallurgical Plant and the Sibay Beneficiating Plant (Republic of Bashkortostan). The direct dependence of phytotoxicity of soils on the content of HM in it at their relatively high concentrations has been established.
