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.

The article presents the overview of the main technological processes in fish structured products dehydration. The rational modes of the technological process of minced fish raw materials with various initial moisture and fat content heat treatment are determined. One of the main tasks of the fish processing industry development which allows increasing the profitability of products and their quality is improving technological processes. The scientifically substantiated choice of resource and energy-saving modes of processing food materials is highly important in this case. It will reduce not only production costs but also emissions of harmful substances into the environment and increase the efficiency of using equipment. It must be taken into consideration that the optimization of dehydration technological processes without identifying their patterns is extremely difficult. Increasing efficiency and controlling technological processes makes sense only on the basis of patterns. The effectiveness of the hydrobionts processing determines the quality and cost of finished products manufacturing while fish processing enterprises working. The development and implementation of highly efficient technologies with the use of resource-saving technical systems, for example, using heat pumps, makes it possible to produce cost-effective high-quality products.

Исследованы потенциальные возможности ресурсосберегающей технологии переработки шалфея лекарственного (ШЛ). Объектом исследования были образцы эфирномасличного сырья – свежеубранные надземные части ШЛ в фазе полного цветения растения и сухие листья ШЛ. Предложенная схема переработки включает следующие стадии: получение эфирного масла; извлечение конкрета из обезэфиренных отходов экстракцией углеводородным растворителем и последующей его отгонкой; получение абсолютного масла и очищенных восков из конкрета отходов; извлечение дитерпеновых соединений экстракцией этиловым спиртом из отходов сырья после обработки гексаном. В результате исследований фракционного состава сырья и особенностей локализации эфирного масла установлено, что массовая доля эфирного масла составляет, % к сухой массе исследуемых фракций: в листьях и соцветиях 2,75, в стеблях 0,31. Рекомендовано введение ограничительных норм по соотношению технически ценной фракции – листьев и соцветий и балластной – стеблей. Полученное из ШЛ эфирное масло имеет высокое содержание туйонов (31,50%), камфоры (21,0%) и 1,8-цинеола (18,80%). Выход дитерпеновых соединений при комплексной переработке эфирномасличного сырья ШЛ на 38,0% ниже, чем из сухих листьев растения. Однако при расчете на сухую массу листьев и соцветий, составляющих 62,3% от массы сырья, показатели отличаются незначительно. Общий выход продуктов, содержащих комплекс биологически активных веществ, составил 15,53 %, что подтверждает целесообразность использования комплексной переработки шалфея лекарственного. The potential of resource-saving technology for processing medicinal sage (MS) has been studied. Samples of essential oil raw materials-freshly harvested aboveground parts of MS in the phase of full flowering of the plant and dry leaves of MS were the object of research. The proposed process flow diagram includes the following stages: obtaining essential oil; recovering a particular from deester waste by extraction with a hydrocarbon solvent and its subsequent distillation; obtaining absolute oil and refined waxes from a specific waste; extraction of diterpene compounds from raw waste after treatment with hexane by extraction with ethyl alcohol. As a result of studies of the fractional composition of raw materials and the features of localization of essential oil, it was found that the mass fraction of essential oil is, % of the dry mass of the studied fractions: 2,75 in leaves and inflorescences, and 0,31 in stems. The introduction of restrictive norms on the ratio of technically valuable fraction – leaves and inflorescences and ballast – stems is recommended. The essential oil obtained from MS has a high content of tuyons (31,50%), camphor (21,0%) and 1,8-cineol (18,80%). The yield of diterpene compounds in the complex processing of essential oil raw materials MS is 38,0% lower than from dry leaves of the plant. However when calculating the dry mass of leaves and inflorescences, which make up 62,3% of the mass of raw materials, the indicators differ slightly. The total yield products containing a complex of biologically active substances amounted to 15,53%, which confirms the feasibility of complex processing of medicinal sage.

The modern building materials market places high demands on heat-insulating and heat-insulating structural materials. In this connection, the issues of developing high-quality building materials obtained on the resource-saving technologies basis allowing to solve two interrelated problems are topical. The first problem is the industrial waste generated and existing stocks disposal. The second is associated with a decrease in the traditional raw materials deficit [1]. These problems solution, combining rational technological solutions, is based on the scientific research achievements in this area, in particular in the foam glass production. The priority scientific research areas in the foam glass materials production are the developments related to the study, the new raw materials use and the production of foam glass mixture compositions on their basis, which provide, along with the necessary performance properties, high environmental safety requirements [2, 3].

Introduction. Rose hips are rich in macro- and micronutrients. Unfortunately, heat treatment destroys most nutrients. Ultrasonic technologies make it possible to reduce the drying time and lower the temperature regime. The research objective was to adjust ultrasound technology to rose hip production in order to reduce the loss of vitamins and improve the quality indicators of the dried product. Study objects and methods. The research featured rose hips of the Rosa canina species collected in the south of Kazakhstan. This subspecies of wild rose is poor in vitamin C. Nevertheless, this shrub is extremely common in Russia and other countries of the Commonwealth of Independent States. The raw material was dried according to standard methods. One group of samples was treated with ultrasound, while the other served as control. Both groups underwent a sensory evaluation and were tested for moisture and vitamin C. Results and discussion. The rose hips were dried in a combination steam oven with a built-in ultrasonic wave generator. The research revealed the following optimal parameters of the ultrasound drying process: frequency of ultrasonic vibrations – 22 kHz, processing time – 2.5 h, temperature in the combination steam oven – +56°C, initial moisture content – 30%. The resulting product met the requirements of State Standard. The loss of moisture was 57%. According to State Standard 1994-93, the initial moisture content should be 15% or less. Time decreased from 360 min to 160 min, and the initial moisture was 13%. The experiment confirmed the initial hypothesis that ultrasonic treatment improves the drying process by improving quality indicators and preserving vitamin C in raw materials using. Conclusion. Ultrasound treatment during moisture removal from rose hips provides a resource-saving technology that fulfills an economically and socially important function.

This paper summarizes the findings of the research aimed at the development of a new method for the integrated processing of naturally occurring and anthropogenic rare-earth raw materials based on the decomposition of rare-earth element (REE) concentrates in the presence of sulfocationite. Sorption and desorption of REE cations on a strongly acidic ion exchanger, sorbent regeneration, and REE recovery from eluates are discussed. A virtually zero-waste integrated process for apatite concentrate is proposed. The generalization of the research findings is aimed at demonstrating the prospects and universality of the proposed resource-saving and environmentally safe approach to the processing of various types of naturally occurring and anthropogenic rare-earth mineral feeds. The new methodology made it possible to develop a number of new hydrochemical processes united by a single approach, providing a qualitative increase in the processing performance of various types of rare-earth mineral feeds. The theoretical foundations of a unified approach to the processing of a wide range of minerals can significantly accelerate and cheapen the implementation of specific process circuits, significantly reduce reagent consumption and waste generation, simplify the separation of rare earth elements and impurities, and the separation of rare earth elements from naturally occurring radionuclides, fluorine, and phosphorus. The study was funded by the Kolarctic CBC 2014-2020 program, Project KO1030 SEESIMA — Supporting Environmental Economic and Social Impacts of Mining Activity.
