The article analyses the application of a composite material based on magnesite cement and red mud for the production of high-resistant materials and structures. Technical characteristics are given proving that this composite has several advantages comparing with other materials and opens up new opportunities for the disposal of toxic wastes and developing new materials with unique characteristics. The advantage of this direction is that the composite material created on the basis of “red mud” has increased strength and water resistance; also, it has the structure of a homogeneous monolithic stone. A wide range of applications of neutralized waste is an undeniable positive factor.

We proposed a new approach to solving the problem of operational analysis and medium-term forecasting of the greenhouse gas generation (CO2, CH4) intensity in a certain area of the cryolithozone using data from a geographically distributed network of multimodal measuring stations. A network of measuring stations, capable of functioning autonomously for long periods of time, continuously generated a data flow of the CO2, CH4 concentration, soil moisture, and temperature, as well as a number of other parameters. These data, taking into account the type of soil, were used to build a spatially distributed dynamic model of greenhouse gas emission intensity of the permafrost area depending on the temperature and moisture of the soil. This article presented models for estimating and medium-term predicting ground greenhouse gases emission intensity, which are based on artificial intelligence methods. The results of the numerical simulations were also presented, which showed the adequacy of the proposed approach for predicting the intensity of greenhouse gas emissions.

Current global environmental challenges and, above all, global warming associated with a change in the carbon balance in the atmosphere has led to the need for urgent and rapid search for ways to reduce greenhouse gas emissions into the atmosphere, which primarily include carbon dioxide as a by-product of human activity and technological progress. One of these ways is the creation of industries with a complete cycle of turnover of carbon dioxide. Aluminum is the most sought-after nonferrous metal in the world, but its production is not environmentally safe, so it constantly requires the development of knowledge-intensive technologies to improve the technological process of cleaning and disposal of production waste, primarily harmful emissions into the atmosphere. Another environmental problem related to aluminum production is the formation and accumulation in mud lagoon of huge amounts of so-called highly alkaline "red mud," which is a waste product of natural bauxite raw material processing into alumina - the feedstock for aluminum production. Commonly known resources and technological methods of neutralizing red mud and working with it as ore materials for further extraction of useful components are still not used because of their low productivity and cost-effectiveness. This article describes the negative impact of waste in the form of "red" mud and carbon dioxide of primary aluminum production on the environment. The results showed that thanks to carbonization of red mud using carbon dioxide, it is possible to achieve rapid curing and its compact formation for safer transportation and storage until further use. Strength tests of concrete samples filled with deactivated red mud were also carried out, which showed the prospects of using concrete with magnesia binder.

The article considers the possibilities of the language of spatial forms that express various emotional states. The design of the urban-resort environment of Sochi becomes a carrier of a certain mood, which makes it figuratively significant. Through cognitive mechanisms, a person is included in the dialogue of reading the environmental text and the allusions, symbols, metaphors contained in it, etc. In an ecological design, the mechanism of synthesis of traditional and experimental aspects is laid down, which are embodied in a form that is accessible to perception through its emotional qualities, which affect consciousness through the synergistic influence of form and content.
