Domestic Raw Materials Research Articles

Внутрішній ринок як фактор розвитку металургійної галузі України

The article considers the preconditions for the transformation of Ukraine's metallurgical industry into a global producer and exporter of metal products. It is shown that this process began in the early 90's of the 20th century, after inheritance, from the former USSR, of a powerful mining and metallurgical complex representing an integrate technological system from extraction and processing of iron ore to the production of finished rolled metal and pipes. An additional factor contributing to the development of the industry's foreign economic activities was its resource potential based on the presence of national highly skilled personnel, domestic raw material base and numerous production facilities able not only to fully satisfy the needs of the domestic market but also provide significant volumes of exports. The authors prove that, due to its export orientation, Ukrainian metallurgical industry of Ukraine has become a hostage to the foreign economic situation, which in adverse periods negatively affects its development. It is shown that this negative influence is manifested, first of all in the decrease of domestic output and exports of metal products, lower profitability of the metallurgical enterprises, and reduction of production personnel. In order to reduce the negative impact of the foreign trade situation on the development of domestic metallurgical industry, the authors have analyzed the experience of the largest steel producing countries. It is proved that the main outlets of these countries are their domestic markets. In particular, the share of domestic consumption of metal products in the five largest steel producing countries in their total metal output in 2015 ranged from 64.5% in Japan to almost 99.1% in Germany, while in Ukraine the share of domestic consumption of metal products in 2015 was only 16.6%. Based on the results of the research, the authors develop and propose guidelines for the reorientation of domestic metal producers to the priority satisfaction of domestic demand through intensive development of domestic metal consumption. In particular, they prove that increasing the domestic consumption of metal products can be achieved through the development and implementation of national programs in industry, especially in construction, engineering, transport, energy and housing and public utilities. Also, the research has proved that expansion of the domestic metal market is only possible with increase in the output of deeply processed metal products and creation of their new types, improved quality and competitiveness, reduced resource intensity of the sector, as well as with innovation based upgrade of machinery and technology for the production of metal products; and reduced environmental hazards. It is impossible to achieve these goals without a radical modernization of the metallurgical enterprises.

Toxin production ability of Bacillus cereus strains from food product of Ukraine

Potential pathogens of foodborne toxic infections – bacterial contaminants Bacillus cereus isolated from plant raw materials and food products from the Ukrainian region were investigated. When determining of the proportion of isolated bacilli from the plant samples, it was established that the epidemiologically significant microorganisms of Bacillus cereus as agents of food poisoning are the second largest. The average value of contaminated samples of Ukrainian plant raw materials and processed products with Bacillus cereus is 36,2 %. The ability of Bacillus cereus strains identified by a complex of morphological, tinctorial, cultural and biochemical properties, to produce specific emetic and enterotoxins was studied. Molecular genetic diagnosis and detection of the toxin-producing ability of isolated 42 Bacillus cereus strains showed both the possibility of their rapid identification and the presence of specific toxicity genes. Multiplex polymerase chain reaction (PCR) was carried out with specific primers to detect toxicity determined of various bacilli genes: nheA, hblD, cytK, cesВ. The distribution of toxigenic genes is significantly different among the Bacillus cereus isolates from various sources. The nheA, hblD and cytK enterotoxin genes were detected in 100, 83,3 and 61,9 % of the investigated strains of Bacillus cereus, respectively. The cesB gene encoding emetic toxin was detected in 4,8 % of strains. Molecular-genetic PCR-method confirmed that all the isolated strains belong to the Bacillus cereus group, and the ability to produce toxins can be attributed to five groups. The main toxins that produce the investigated Bacillus cereus strains were nhe and hbl enterotoxins encoded by the corresponding genes of nheA and hblD. The enterotoxic type of Bacillus cereus was predominant in Ukrainian region. Studies of domestic plant food raw materials and products have confirmed the need to improve microbiological control of product safety by introducing accelerated specific diagnostics of contaminants by molecular genetics methods.

Research of the effects of technological factors on the quality indices of high oleic sunflower oil

The object of research is high oleic sunflower oil (HOSO) and refined deodorized sunflower oil (RDSO) as a control. The distinguishing characteristic of HOSO consists in the changed fatty acid composition , has a high content of triglycerides of oleic acid more than 89 %. HOSO has the following characteristics: (ρ=915...920 g/cm 3 , η=0.0180±0.0009 Pa, t (solidification)= 0...-6 oC, refractive index 1,466...1,468; Tb N = 0. 0100±0.0003 mg MA/1000 g, PN =0.83±0.02 mmol ½ O/kg , SN =184...194 mg KOH, AN =0.112±0.003 mg KOH/g; IN =105±5 % I 2 ; =3.00±0.09). One of the most problematic places for using oils is that they are faster than solid fats, refreshing products has less shelf life. In the course of the study, the influence of technological factors on the HOSO properties and the scientific basis for the HOSO use as a prescription component of food systems i s determined. It is proved that during the storage HOSO is more resistant to processes in comparison with RDSO , since glycerides of polyunsaturated fatty acids oxidize faster than monounsaturated, confirming the experimental data of physicochemical parameters, fatty acid composition and dynamics of the content of tocopherols. HOSO stability for oxidation processes under conditions of prolonged thermal action in comparison with RDSO (control) by functional numbers (acid, peroxide, iodine, thiobarbituric) is studied. It is found that the oxidation rate in HOSO is lower than in theRDSO (control) by 2 times at the beginning of the heat treatment and by 1.23 times with the maximum duration of heat treatment. The coefficient of extinction grows to the limit of maximum permissible values at 6 hours in RDSO and 18 hours in HOSO, which confirms the HOSO thermal stability that is 3 times greater. Essential changes in the fatty acid composition and in the complex of tocopherols of oils under heat treatment conditions, the nature of which depends on the type of oil and the duration of heat treatment, are also shown, which also indicates a greater stability of HOSO for oxidation processes in comparison with RDSO (control). On the basis of the research, recommendations are developed on the HOSO use in the technology of custard products and as a medium for frying. Rational conditions of the brewing process are t=95...100 oC, τ=(3...5)×60 s, hydromodule «HOSO-water» – 1:2.5. Recommended parameters for the HOSO use as a medium for frying, in particular deep-fried: t=160...180 oC, duration of continuous use τ=(0...18)×60 2 s, ratio « HOSO – semifinished product» is 4: 1, HOSO storage time is 24 months. Thus, HOSO use will ensure the use of domestic raw materials; the maximum realization of the functional and technological properties of HOSO with obtaining high-quality products; reduction of energy costs and labor intensity of the process; introduction of resource-saving technologies using the newest principles of food production.

Efficiency Analysis of Indonesian Coffee Supply Chain Network Using A New DEA Model Approach: Literature Review

A position of Indonesia as the world’s biggest producer of robusta coffee has declined. Currently, Vietnam is the main producer of robusta coffee in the world. A decline in Indonesia's position is due to saturation of the Indonesian coffee export destination countries which results in declining demand for export of Indonesian coffee. The quantity of Indonesian robusta coffee supplied to the international market depends on secured supply of domestic raw materials and the efficiency of supply chain network. Efforts to ensure the domestic coffee supply is done through efficiency analysis on each member of the supply chain that forms the supply chain network. Efficiency measurement in supply chain network is performed using the New DEA Model developed by Liang et al. The measurement technique of DEA is gradually the efficiency of the production unit (product flow) of each actor (seller and buyer) on the supply chain. The efficiency level of each actor can determine the efficiency of the supply chain network. This is because of the relationship of input and output between seller and buyer so that the final output of supply chain network will produce. New DEA model is more appropriate to use in supply efficiency mechanism that can be cooperative.

Tialit- and mullite-tialite containing ceramic in the MgO—SiO2—Al2O3—TiO2 system based on domestic raw materials

The aim of the paper is to justify the choice of the region of the system MgO—Al2O3—TiO2—SiO2, which is promising for the production of functional ceramics under conditions of low temperature synthesis. The structure of the A3S2—M2A2S5—AT—S tetrahedron in detail is considered (Тe = 1400 °C), it found that the minimum eutectic of this region is four-component. Compositions based on the above-mentioned tetrahedron are promising for the synthesis of chemically and thermally stable ceramics. Optimization of tialite and mullite-tialite ceramics at a synthesis temperature of 1250 °C has been carried out while maintaining the ratio MgO : TiO2 = 0.18 in the raw mixtures. The dependencies of the properties of materials on the compositions of the ceramic masses were received by mathematical modeling. Mass compositions of functional ceramics in conditions of low-temperature synthesis with high performance indicators have been developing.

Influence investigation of the type and amount of the new active aluminas addition on the properties of products from low-cement corundum chromium-containing castable mass

The influence of new active aluminas addition (NABALOX NO 635 and NABALOX NO 713-10 MF) and its amount on the properties of non-burning and fired at 1580 оC samples has been studied. It was established that, the compressive strength of non-burning samples, depending on the type and amount of the active alumina addition, is maximal when 5 % of the active alumina NABALOX NO 635 is added. After high-temperature firing, the densest structure is formed in the samples of this composition, as evidenced by their indices properties: open porosity of 23.3 %, apparent density of 3.03 g/cm3, compressive strength of 115 N/mm2. As a result of the carried out researches, the technology of products manufacturing by vibrocasting method from the low-cement corundum chromium-containing castable mass has been improved by adding the new active alumina of NABALOX NO 635 instead alumina grade of CTC-40. This technology provides manufacturing of products with higher compressive strength (115 vs. 104 N/mm2) and a larger apparent density (3.03 vs. 3.02 g/cm3) with substantially equal open porosity values compared to those of earlier manufactured products containing of active alumina addition grade of CTC-40. Based on the economic feasibility, as well as the availability and the possibility of purchasing NABALOX NO 635 alumina in small batches on the domestic raw materials market (“Nabaltec AG”, Germany, has a representative office in Ukraine), its use for manufacture of the low-cement corundum chromium-containing castable mass is more preferable compared to with the previously used active alumina grade of CTC-40 produced by “Almatis GmbH” (Germany). As a result of the carried out researches, normative documentation has been developed. According to this documentation, in the conditions of PJSC “UKRNIIO NAMED AFTER A. S. BEREZHNOY” full-scale samples of products characterized by high properties were produced: compressive strength after hardening in humid conditions for 7 days of 63 N/mm2, open porosity of 23.3 %, an apparent density of 3.03 g/cm3, compressive strength after firing at a temperature of 1580 оC of 94 N/mm2.

Pyrometallurgical Treatment of a Nepheline Charge Using Additives of Natural and Technogenic Origin

Prospects for developing the domestic raw material mineral base for producing aluminum and alumina are connected to a significant extent with the development of low-grade resources of natural and technogenic origin. There is considerable potential in unused tailings of apatite-nepheline ore flotation enrichment, natural aluminum silicate within the composition of urtite, ristschorrite and other alkaline rocks. Features are established for a change in indices for opening ore resources during pyrometallurgical treatment of a limestone-nepheline charge and subsequent leaching of sinter in relation to process temperature, nature and amount of raw material additions that make it possible to suggest a fundamental production scheme for inclusion into existing alumina production, i.e., the main raw material for electrolytic primary aluminum production.

К ВОПРОСУ О ВОЗМОЖНОСТЯХ КЛАСТЕРНОГО АНАЛИЗА ПРИ РАЗРАБОТКЕ РЕГИОНАЛЬНЫХ СТРАТЕГИЧЕСКИХ ДОКУМЕНТОВ

This article focuses on the problem how to classify regions according to their industry specialization using cluster analysis methods. There were selected 12 relative indicators as clustering parameters characterizing the importance of seven different sectors for the regional economies and the degree of state support of enterprises in these sectors. The classification procedure allowed to divide the studied regions into six clusters, each cluster received its working title. The first cluster is titled agro-industrial; it is characterized by the excessive national average indicators of the degree of state support in agriculture and power engineering in 2.4 and 1.6 times, respectively. The second cluster - industrial-presents regions with a high proportion of manufacturing activity using mainly imported raw materials. In the regions of the second cluster the federal government actively develops not only manufacturing and power engineering but power generation as well, 30.06% and 14.48% of total public investment, respectively. The third cluster - agricultural and construction - consists of traditionally agricultural regions and regions with rapidly developing construction sector. However, despite the fact that the value of agricultural industry in the third cluster regions is 2 times higher than the national average value, the degree of public support for the industry is still quite low. The fourth cluster - industrial and mining - brings together fifteen largest industrial regions, their activities are almost entirely provided by the domestic raw materials and energy stocks, which qualitatively distinguishes them from the second cluster regions. The fifth cluster - oil and gas production - is formed by seven richest regions in the federal districts of the Urals and the Far East, as well as the Nenets Autonomous District; these regions are characterized by the highest rates in mining industry. The sixth clusters - transport and power engineering - presents the group of regions with well-developed transport infrastructure and power engineering, many of them are major transport junctions in Russia. The results obtained are quite logical, appropriate and prove the effectiveness of the cluster analysis when processing large data sets. This fact confirms the validity and applicability of the cluster analysis in drafting regional strategic documents.

Ринкові можливості та загрози молокопереробних підприємств України

У сучасних умовах молокопереробні підприємства зіткнулися із великою кількістю загроз для подальшої своєї діяльності. Вони пов’язані насамперед зі скороченням величини попиту на їхню продукцію на зовнішньому ринку через призупинення експортних поставок продукції у Росію, зменшенням доходів населення України і відповідно величини внутрішнього попиту, низькою якістю вітчизняної сировини, зменшенням її обсягів та зростанням цін на неї, збільшенням обсягів закупівлі молокопродуктів у приватних та фермерських господарствах населення. Проте останнім часом з’явилися і нові ринкові можливості для молокопереробних підприємств, які обумовлені зростанням в Україні обсягів поставок молока екстра ґатунку як сировини для подальшого виробництва, збільшенням попиту на молочні продукти з боку країн Близького Сходу та Північної Африки, Китаю, що вимагає дослідження споживчих уподобань на відповідних ринках. Для утримання існуючої та збільшення частки ринку України молокопереробні підприємства повинні приділяти увагу заходам паблісіті та стимулювання збуту для пропагування споживання саме продуктів промислового виробництва.

Advanced CtL/CtG technologies for lignite

Conversion of coal into dedicated hydrocarbons has been developed in the beginning of the last century and is still practiced in areas of the world with scarcity or insecure oil and gas supply.Given the need for carbon in chemistry, possible political disruptions in oil and gas producing regions and the rise of renewable energy, lignite, as a secure domestic raw material, can serve as a chemical feedstock. Furthermore, it can serve as an energy storage using polygeneration, i.e. the ratio between power and hydrocarbon products can follow the fluctuating grid requirements.In North-Rhine Westphalia (NRW), a committee for inquiry regarding the future of the chemical industry advocates this idea in its final report released in April 2015. This is in line with the position of RWE Generation (RWEG), which has been pursuing an alternative use of lignite besides the generation of electricity and has been expediting the related technology development for decades. So far, economical reasons prevented this option to be realized in commercial scale in Germany during the last 30years.Together with partners from science, as well as industry and partly government-funded, RWEG develops innovative plant concepts and technologies for Coal-to-Product concepts. Especially the challenges and chances are taken into consideration resulting from the given circumstances, a changing market situation and shifting political goals.To meet the challenge of high investment costs, RWEG pursues a so called annex approach to improve the economic viability of the alternative use of lignite. Annex means to use synergies on infrastructure at established power plant or chemical sites, when planning a CtL/CtG plant.In addition, the process steps are critically questioned, here the gas treatment plant, whether amine-scrubbing can be applied as a less costly alternative to the commonly used Rectisol scrubbing.To reduce the CO2 footprint and to use renewable energy for hydrocarbon products, there is, next to the way of integrating electrolytically produced H2 into the process, another way, to substitute carbon consumption needed for the gasification temperatures by electrical heating.

ABAKA (Musa textilis Nee) SEBAGAI SUMBER SERAT ALAM, PENGHASIL BAHAN BAKU PULP / Abaca (Musa textilis Nee) As Thesourceof Naturalfiber, Producingraw Materialfor

Abaca-producing natural fiber as raw material for pulp paper money. Natural fibers derived from abaca, have environmentally friendly nature and local wisdom, highly favored by consumers manufacturer. Nowadays the need for abaca fiber in the country is still imported. Pulp and paper are derived from abaca has advantages including a tear-resistant, when it becomes difficult falsified paper or paper produced is used for Paper that is difficult to imitate, stamp paper dukomen (seals, certificates, diplomas and other important papers). Bank Indonesia (BI) in 2014 is more serious to use raw materials of cotton fiber and abaca fiber in the country. This is in accordance with the Currency Act N0. 7 Year 2011 on article 9 (2) in order to give priority to domestic raw materials (local) to maintain the quality, safety and competitive prices in the printing Rupiah. The first harvest abaca at age 18-20 months after planting. At that time there has been no income for farmers, their inter-cropping between chili + abaca provide a source of income, because chili is a seasonal crop that yields chilli can assist in meeting the needs of farmers in financial trouble. Besides, there is no plant stand (Jabon, or sengon). The pattern of intercropping abaca + small chilli may generate profits of Rp. 21.333 million, - thus the development of abaca has good prospects. The purpose of the writing of this review is to provide support for the existence of abaca development innovation as a source of natural fiber which contribute in providing raw materials of paper money dicanakan by Bank Indonesia and to create employment in rural areas, and provide a source of income of farmers.

Taking the Step towards a More Dynamic View on Raw Material Criticality: An Indicator Based Analysis for Germany and Japan

Due to mounting concerns about the security of raw material supplies, numerous studies dealing with the quantification of supply risks and material criticality at the national level have been carried out in previous years. Regarding these studies, most approaches are indicator based static screening methods analyzing large numbers of raw materials and identifying those which are most critical for an economy. The majority of these screening methods quantify supply risks and vulnerabilities for one base year without taking into account temporal changes. Dynamic approaches for specific raw materials analyzing affected value chains in detail have been introduced recently; however, these studies do not intend to provide a screening of larger numbers of commodities. In this paper, we present a simple dynamic screening approach to assess raw material criticality at the country level building upon methods from innovation economics. The indicators applied in this study are only based on broadly available production and trade data, which makes this approach relatively easy to apply. We test our methodology on the example of Germany and Japan—two economies with highly specialized industries and low domestic raw material deposits, and, hence, high import dependency. The results are comparable to those of previously conducted multi indicator based static screening methods. However, they provide additional insight into temporal developments over the previous decade.

Ценообразование в сахарной промышленности как приоритет обеспечения продовольственной безопасности страны

Российская экономика в целом и большинство отраслей промышленности продолжают оставаться высокозатратными и неэффективными, что предопределяет их неконкурентоспособность. Типичным представителем таких отраслей является сахарная промышленность, являющаяся монопродуктовой отраслью. С одной стороны, сахарная промышленность характеризуется жесткой привязкой к единственному отечественному источнику сырья — сахарной свекле — и большой степенью рисков в ее производстве и переработке, обусловленных влиянием разнообразных условий земледелия и колебаний природно-климатических факторов. С другой стороны, от эффективности использования этих ограниченных сырьевых ресурсов и возможностей отрасли по производству сахара зависит степень удовлетворения потребностей населения в жизненно важном продукте, а также отраслей пищевой и фармакологической промышленности. Сегодня в условиях экономических санкций возросла роль импортозамещения в целях защиты национального производителя, обеспечения эффективности и конкурентоспособности сахарной промышленности. Принципиальное значение в системе взаимоотношений производителей и переработчиков свеклосырья имеет механизм ценообразования. Высокая полная себестоимость сахара, вырабатываемого в межсезонье из импортного тростникового сахара-сырца, определяет верхний порог внутренних цен на данный вид продовольствия. Кроме того, высока и себестоимость импортного семенного материала, средств защиты урожая и наличие импортной специализированной техники. Эти обстоятельства являются стимулом в развитии импортозамещения по стратегически важному продукту — сахару. Авторами предпринята попытка проанализировать формирование потребительской оптово-розничной цены на сахар-песок, произведенный из разных источников сырья — сахарной свеклы и сахара-сырца. Полученные результаты позволяют обоснованно говорить о конкурентоспособности и эффективности производства сахара из отечественного сырья, даже без учета таможенных пошлин на сахар-сырец.

Research and Development Project on the Domestic Raw Materials of Enamel for Jewelry Production

The project aims to produce quality enamel colors from locally available materials in order to reduce costs. In the course of the research, information is collected on imported enamel colors and a study is carried out on chemical compositions and quality of the colors. At the same time, there is a study on local materials which can potentially be used to produce enamel colors, starting from basic colors such as red, blue and green. The study has found that the imported enamel colors qualify as lead glass because it contains 23-28% of lead. The study has also found that red enamel (transparent) blue enamel (transparent), blue enamel (opaque), green enamel (transparent), and green enamel (opaque) have similar level of density and hardness. Red enamel (opaque) has lower level of density and hardness due to its porosity which can be observed with naked eyes. The COE level is similar for all of the tested colors because their chemical compositions are similar. The study produces quality blue and green enamel at much lower cost. Colors of the enamel are achieved by adding different metal oxide. The color blue (translucent and opaque) is from adding cobalt (Co). Chromium (Cr), manganese (Mn), iron (Fe), cobalt and copper (Cu) together produces translucent dark green, while chromium and copper (without cobalt) produces opaque as lighter green. However, it has not been able to produce red enamel yet but has requested for samples from another research project “Developing New Technology to Produce Jewelry from Synthesized Red Crystal” for further study.Keywords: Enamel; Jewelry; Glass; Local Raw Materials

'Import Preservation' in Lieu of Import Substitution

Import substitution in the Russian industry shows obvious signs of a slowdown. Both comparative results of actually implemented import substitution quarter-on-quarter and plans of enterprises for the last quarter of the current year attest to this. At the same time, import substitution of machines and equipment was at a higher rate than import substitution of industrial inputs. It is true that the Russian machine building industry does not reduce procurements of imported equipment. The food processing industry is losing momentum in import substitution of inputs either having disillusioned in the domestic raw material base or having exhausted its potential. Significant part of the Russian industry pursues a policy of “import preservation” (in other words, does not reduce the share of imports) or even goes to “import expansion”. The latest assessment of the actual import substitution has been obtained for Q3 and forecast one for Q4 2015. Herewith, estimates of import substitution regarding industrial inputs was done separately from import substitution of machines and equipment. According to the obtained results for Q3 2015 one can make a rather definitive general conclusion: the Russian industry has reduced the scale of import substitution. This refers to all indicators: inputs, equipment, actual changes and plans for Q4 2015. Let us conduct an in-depth analysis of import substitution taking into account comparable results for Q2 2015.
