The article deals with issues of monitoring, planning, organizational and technical support, economic regulation and improving the efficiency of the infrastructure for processing, recycling and disposal of waste, resource conservation and management of secondary resources, their use as secondary raw materials for production, services, work and power generation. The Russian Federation has significant potential for economic growth due to the efficient use of secondary resources from billions of tons of generated production and consumption waste annually. These ecologically unsafe anthropogenic objects can be characterized as a source of valuable renewable raw materials, material and fuel and energy resources. However, the scale and level of use of various types of secondary resources are characterized by considerable unevenness and depend on the demand for secondary raw materials, the resource value of the waste, the environmental situation arising from treating them as environmental polluters, on the real economic conditions that determine the profitability of each specific type. economic activities that use secondary resources for the manufacture of products, works, services, energy production. The methods of monitoring the industry for the treatment, disposal and disposal of waste are: information-analytical, information-statistical, sociological, geo-information. The legal status of the monitoring system of the industry for the treatment, disposal and disposal of waste is determined by the limitations of its functionality within the framework of the goals and objectives facing it.

Systemic Nature

Research in the sphere of the Arctic industrial development often leads to the identification of clear regulatory gaps of a systemic nature. A particular example is the issue of legislative regulation of the involvement of secondary raw materials, fuel and energy resources in economic use and property turnover in the context of resource conservation and resource efficiency. In this case, secondary resources are not subject to independent regulation in general, but only as one of the elements of activities related to environmental protection. Accordingly, the conditions for the development of a system of production and consumption wastes’ effective management, the creation of a recycling industry, including the reuse of such waste, have not been formed yet. The results of the analysis given in this research paper clearly indicate the lack of development of mechanisms for stimulating the use of non-target materials and substances. Industrial enterprises that use secondary resources in production do not currently receive special advantages within the framework of the implemented industrial policy. System benefits are universal and directly related to commodity production only. However, it is necessary to apply measures to encourage industrial activities to implement projects involving the reuse of secondary resources in production, including in the Russian Arctic.

Beet sugar production is one of the material-intensive industries, where the volume of raw and auxiliary materials used in production is several times higher than the output of finished products. It is also a source of multi-tonnage secondary resources, i.e. by-products and production waste, the main ones beingAbeet pulp, molasses and filtration sludge. Against the background of the implementation of the Sectoral Program of Beet Sugar Production Development in the Republic of Kazakhstan for 2018-2027, there is a need to create a concept of ecologization of production, which will provide for the development of fundamentally new technologies to ensure minimum waste, combining environmentally friendly methods with cost-effective production of sugar beet and by-products. The bet should be made on low-cost technologies that will minimize production costs and environmental impact. In this article possible variants of sugar beet processing technologies with complex deep processing of waste are offered. The comparison of traditional technology and various variants of progressive technologies of sugar beet processing and production of new products from secondary resources was carried out, which allowed to determine revenue from complex processing of 1 ton of sugar beet.

In the present research, the combined utilization of fly ash (FA), derived from a lignite-fed power station, along with scrap-soil (SS), a steel industry by-product, is investigated, for the development of eco-friendly ceramics, thus enhancing innovation and sustainability. The valorization of these low price and largely available industrial secondary resources as 100% the raw materials mixture in ceramic industry arises interesting technological, environmental and economical benefits. FA and SS were mixed in various proportions (0-70%wt. in SS), cold compacted at 20 tn load using an automated hydraulic press to form a series of 5 cm diameter disc-shaped specimens, and finally sintered at three different peak temperatures (1000oC, 1100oC and 1140oC) for 3h. Then, the specimen microstructure and physico-mechanical properties were characterized. According to the experimental results, a sintering temperature increase from 1000°C up to 1140oC significantly improves specimen densification, thus sharply enhancing the diametral tensile strength (DTS), from 0.5 MPa up to 12.8 MPa respectively for a 50-50%wt. FA-SS mixture. Mechanical strength also varies with the SS percentage in the raw materials. Physico-mechanical properties seem to be constant for specimens containing SS up to 60% at 1140oC.

В настоящее время вовлечение вторичных материальных ресурсов в производственный цикл и, как следствие, предотвращение образования отходов - одно из приоритетных направлений развития пищевой и перерабатывающей промышленности в области совершенствования пищевых производств. Плоды аронии, как сырье для промышленной переработки, используются для получения разнообразной продукции, в том числе сиропов, соков, безалкогольных напитков, вин и крепких напитков, в процессе производства которых образуются вторичные сырьевые ресурсы - некондиционное сырье, выжимка (кожица, семена, косточки, часть мякоти), отстой, осадки и др. Целью работы было получение антоцианового красителя из вторичных ресурсов плодового виноделия, выжимки аронии черноплодной. Для максимального извлечения антоцианов из выжимки проводили 3-кратную экстракцию спиртом этиловым ректификованным (96%об.) и водно-спиртовым раствором (45%об.). В полученных образцах красителей исследовали качественные показатели: растворимость, содержание сухих веществ, содержание красящих веществ, термическую стойкость. В результате проведенных исследований была установлена эффективность экстракции красящих веществ из выжимки сушеной и замороженной (без размораживания), с использованием в качестве экстрагента спирта этилового ректификованного. Полученные антоциановые красители устойчивы к воздействию температур до 70 °С. Предложенный способ получения антоциановых красителей из аронии черноплодной характеризуется мягким режимом извлечения красящих веществ без применения высоких температур, позволяет минимизировать количество технологических операций и энергозатрат. At present, the involvement of secondary material resources in the production cycle and, as a result, the prevention of waste generation is one of the priority areas for the development of the food and processing industry in the field of improving food production. Chokeberry fruits, as a raw material for industrial processing, are used to obtain a variety of products, including syrups, juices, soft drinks, wines and spirits, during the production of which secondary raw materials are formed - substandard raw materials, pomace (peel, seeds, part of the pulp), sludge, sediments, etc. The purpose of the work was to obtain anthocyanin dye from secondary resources of fruit winemaking, chokeberry pomace. To maximize the extraction of anthocyanins from the pomace, a 3-fold extraction was carried out with rectified ethyl alcohol (96% vol.) And an aqueous-alcoholic solution (45% vol.). In the obtained samples of dyes, qualitative indicators were researched: solubility, dry matter content; content of dyes, thermal stability. As a result of the research, the efficiency of the extraction of dyes from dried and frozen pomace (without defrosting) was established, using rectified ethyl alcohol as an extractant. The obtained anthocyanin dyes are resistant to temperatures up to 70 °C. The proposed method for producing anthocyanin dyes from chokeberry is characterized by a mild regime for extracting dyes without the use of high temperatures, which makes it possible to minimize the number of technological operations and energy consumption.

Mining Residues

Electroremediation and deep eutectic solvents are well-documented clean-up processes for metals extraction from solid matrices. Depending on the purpose, these treatments may generate a residue free of pollutants and critical raw materials. Several studies were conducted to re-insert treated secondary resources in building materials. However, there is a research gap in the improvement of reactive properties of these secondary resources. In addition, there is a lack of pozzolans that can optimize cementitious materials. This study investigates the pozzolanic reactivity of tungsten mining residues after receiving electrodialytic treatment in the presence of natural deep eutectic solvents. In all cases, thermal treatment after electroremediation potentiated the pozzolanic reactivity of tungsten mining residues, between 64% to 87%. The introduction of these pozzolanic resources in cementitious-based materials may increase their performance, enlarge the range of applications in the construction industry, reduce the environmental impact, and contribute to a circular economy. Keywords: electro-based technology, tungsten mining waste, construction material, pozzolanicity.

Problem statement.The solution to the problem of the integrated use of secondary construction resources should be considered in the context of the spread of the world practice of using, processing and reclaiming all valuable waste as secondary resources. This is due to profound changes in the world economy associated with limited natural resources, threats to environmental and social security, an increase in the amount of waste and man-made landfills.The process of managing the flows of secondary resources should be aimed at achieving economic and environmental effects, the definition of which has certain characteristics for various stakeholders in this process: (producers of building materials (waste recyclers), developers (construction companies and organizations), the construction industry (at the regional level, countries).The application of world experience in the use of secondary resources in the construction industry can become the basis for the development of infrastructure for obtaining secondary raw materials from construction waste and attracting them into re-circulation, which will make it possible to more effectively implement the National Waste Management Strategy until 2030, adopted by the Government of Ukraine.The goal of the strategy is to introduce a systematic approach to waste management at the state and regional levels, to reduce the volume of waste generation by increasing the volume of their processing and reuse. Purpose of the article: substantiate the effectiveness of the use of tools for integrated management of secondary resource flows in the construction industry and propose an economic and mathematical model for optimal management of construction waste flows at the level of individual enterprises of the industry in the region. Conclusion. The toolkit for managing waste streams in the construction industry includes information (including statistical, monitoring), analytical, predictive tools for managing the flows of secondary resources. We consider the creation of a unified system of integrated management of the flows of secondary resources (materials) as a condition for decision-making and the effectiveness of the overall management of waste streams in the construction industry, the main goal of which is to achieve a cumulative economic effect from attracting construction waste to a repeated production cycle.The effectiveness of the use of tools for complex management of the flows of secondary resources in the construction industry has been substantiated and a method is proposed for its determination, on the basis of a mathematical model for solving the problem of optimal management of flows of construction waste at the level of enterprises are waste producers, enterprises-processors (producers of building materials from secondary raw materials), the construction industry of the region.
