This paper describes the first experience for Uzbekistan in mammals' fauna inventory in the context of large administrative districts. Tashkent region was chosen as a model territory for researching – as an integral natural area with natural geographical boundaries. A revision of the composition and assessment of the fauna current conditions of economically significant mammals of this region was carried out. The primary limiting factors and threats to the existence of these species were analyzed. The permissible standards for the removal of economically significant mammalian species from the natural environment were determined, based on the data of the abundance and their habitats conditions. Standard approaches and methods for inventory have been developed: data collection and storage; working with sources of existing information; field research as the gaps closing basic method. Based on the results of the research, standard species profiles were prepared for 17 economically significant mammalian species, including data on distribution, landscape location, abundance, and permissible operational loads. A proposal to change the current conservation status of the Long-tailed Marmot, Corsac Fox and Steppe Polecat was justified. These species were previously considered as hunting objects, but now they have become rare. The impact of introduced and invasive species – Coypu, Muskrat, American Mink and Norway Rat on the native fauna was determined. The analysis of negative impacts on the species allowed to recommend a number of applied measures for the sustainable use of biological resources.

Comparatively, the results of experimental studies of pyrolysis of bio-plant material and oil sludge were studied, which gave similar results. The article provides scientific and technical information on the problems of processing solid waste and residues of biological origin. It has been shown that by thermal destruction, it is possible to obtain hydrocarbons of a gaseous, liquid consistency, and solid mass, preferably consisting of hydrocarbons with a small number of hydrocarbon residues.

Development of proposals for adapting the existing methodology for calculating the available throughput to the operating conditions of the railways of Uzbekistan, taking into account the factors that ensure traffic safety when passing high-speed passenger trains. Methods: Grapho-analytical approaches and a comparative analysis method were used to determine the throughput of railway lines with mixed train traffic. Results: The main factors influencing the capacity of lines, advantages and disadvantages for each existing method for determining the capacity of railway lines are given. To assess the quality of transportation processes on railway lines, experimental train schedules were constructed. Based on the analysis of their indicators, a formula was proposed for calculating the throughput on double-track lines when passing high-speed passenger trains. Practical significance: The application of the proposed methodology improves the calculations of the performance indicators of sections with an unparalleled train schedule.

Poor infrastructure quality hinders the country's stable economic growth and competitiveness in international markets. The quality of life declines when the infrastructure is underdeveloped. Public-private partnership allows attracting additional sources of funding and receiving additional privileges from the state. Public-private partnerships in infrastructure benefit the economy, national politics, the private sector, as well as the population. The article examines the features of the formation and development of public-private partnerships in the development of the national economy of the Republic of Uzbekistan. The directions of innovative development are selected. The problems that require solutions for the continuous development of an innovative economy are identified. The aim of the study is to reveal the essence of public-private partnership in infrastructure, analyze the current state and its role, place in the economy of the Republic of Uzbekistan. The object of the research is economic relations in relation to public-private partnerships associated with the process of communication between the state and interested individuals, legal entities and international organizations. The subject of the research is the economic, social, legal aspect of the functioning of the forms of public-private partnership in the implementation of the functions of the state. The methodology laid the foundations for general scientific methods, general logical methods of cognition, systemic, logical, analysis, synthesis, deduction and induction, modeling and other methods. Based on the results of the study, conclusions were drawn to increase the attractiveness of PPP implementation in infrastructure.

The agro-industrial complex (AIC) is becoming one of the main in the economy of Uzbekistan. In recent years, work has been carried out to reform it fundamentally. The normative and legal framework for its functioning has been formed, public administration has been improved. The market mechanism of management is being introduced. Investments are attracted. The structure of acreage is optimized by reducing cotton crops and placing fruit and vegetable crops on them. New intensive gardens and vineyards are being created, innovative greenhouses are being built. Work is carried out on construction and reconstruction of collectors and hydraulic structures, refrigeration chambers for fruit and vegetable products’ storage, introduction of new equipment and technologies in it. The processing industry is developing, the volume and range of products is increasing, including innovative and its export. Integration of producers and processors of agricultural products is intensifying. At the same time, there are still significant reserves in the agro-industrial complex of Uzbekistan. The efficiency in natural resources’ use is low. The irrigated agricultural land are is small. The technical and digital equipment of personal subsidiary farms and labor productivity in them are low. Uzbekistan is implementing a course for innovative development. The President of the Republic approved the Strategy for the agriculture development of the republic for 2020-2030. It sets the tasks of significant increase in the production and processing of agricultural products, expanding its range due to new types of products and its exports. The strategy is successfully executed. Nevertheless, it is necessary to improve the state management of the agro-industrial complex, the introduction of the market management mechanism, the development of interactions between the complex’s branches, strengthening export potential of the complex, introduction of innovations, digitalization of enterprises’ activities.

The Angren coal mine has 2 billion tons of reserves of various grades of lignite that can be used as fuel, of which 2BR-B2 and 2BOMSSh-B2 lignite grades, which have 2 million tons of reserves, remain unusable due to poor quality and low combustion heat. [1]. To improve the quality of these coals, water treatment technology has been developed. Technological schemes, gravitational flotation methods were studied. The ash content of coal was reduced, and the heat of combustion was increased. Scientific results have been obtained to apply the mixture as a technological waste in the glass industry. In particular, the properties of raw materials for brown tara bottles were studied. The brown glass was obtained by adding the resulting mixture as a technological waste, and its properties were studied.

Scientific and industrial development and the introduction of new technological processes are leading to increasing environmental pollution. In order to prevent an environmental catastrophe, it is necessary to establish a comprehensive environmental monitoring system, which allows for systematic information on the state of the natural environment. The developed method of extraction of iron (III) and the spectroscopic determination of iron directly in the organic phase differ from the existing selectivity, sensitivity, simplicity, rapidity and is recommended for the analysis of production solutions, waste water, ores, concentrates and other chemically complex materials without separation of accompanying elements directly in the organic phase.

Food safety is one of the most important and actual problems of the humanity. It is well-known and approved that a country is in safe food situation only in case when it independently produces essential foodstuffs at least 80% of its self-sufficiency level. The current situation is forcing us to achieve the independence from imports. In our research, we make an accent to farther development in the domestic fruit and berry manufacturing processes, which implies general enlarging the product assortment and making it available for customers countrywide. To re-tool the industry with hi-end equipment; to improve raw material storage bases, located in the regions of most intensive consumption; to develop and introduce some innovative and ecologically safe fruit and berry raw materials processing technologies. To pay an extra attention to quality and safety of fruit and berry raw material and ready product. To expand production of canned, frozen, dried products assortment and make it ecologically clean and highly competitive compared to the imported ones. In addition, to make marketing analysis on the attractiveness of a product package for customers and dispose of dependence between processing enterprises and raw material bases.
