Despite some decisions approved by the Government of Ukraine to address the problems of efficient and environmentally sound solid waste management, in particular those that accumulate as a result of economic activity of the agro-industrial complex of the state, their practical implementation of measures declared by the Government is currently low. levels. Among a number of deterrents, the main ones include: lack of centralized recycling facilities and economically accessible for small facilities technical and technological base of waste processing, ineffective environmental control and the necessary management practices. However, vegetable waste is not always used, although it is a valuable raw material that can be used as a raw material for the production of fuel pellets, which will significantly reduce the energy dependence of the enterprise. An integral part of the technological cycle of processing plant residues into fuel briquettes is the preparation of biomass for briquetting in order to ensure the required particle size. Given the strategic importance of the formation of material and technical base to ensure highly efficient processing of agricultural waste of plant origin, as well as high energy consumption, which marks the traditional preparation of biomass for briquetting, there is a need for research to solve the problem of energy efficient grinding of structurally heterogeneous materials. high moisture content, which determines the relevance of the article. Thus, in order to achieve high efficiency of the process of grinding waste of plant origin, promising ways to reduce the energy consumption of this process based on the energy balance of the vibratory crusher rotor type and analysis of relationships between elements of the structural block diagram of the energy balance of the technological system "Vibration-rotor crusher - the processed environment ".

The Impact

For many years, the technological deterioration of physical assets, the high energy intensity of production, structural imbalance of the industrial complex, and related complex technogenic and ecological situation, which today already carries systemic threats, remained acute problems for Donbass. The conflict in eastern Ukraine has exposed these problems, made them admit that without the introduction of advanced technologies and effective management solutions, it will hardly be possible to revive the economic potential of the region on a qualitatively new basis. The paper concentrates on the search for opportunities to mitigate and eliminate the impact of the challenges existing in Donbass, implement the restructuring of the region's economy by using the tool of science parks. The practicality of organizing and financing science parks is now being worked out by the Ministry of Reintegration of Temporarily Occupied Territories of Ukraine within the Strategy of Economic Development of the Donetsk and Luhansk regions until 2030. The experience of other countries of the world regarding the goals and methods of creation, element composition, specialization, construction cost and the effectiveness of the activities of scientific parks with the aim of using it in the regeneration of Donetsk and Lugansk regions has been studied. The article reflects the experience of the USA (in particular, the Silicon Valley and Research Triangle Park science parks); Ireland (Wyeth Biopharma Science Park); Germany (Rhein Elbe Science Park); Poland (Poznan Science and Technology Park, Park Naukowo – Technologiczny «Technopark Gliwice», Science and Technology Park Poland-East in Suwałki). Based on the results of the analysis, it was determined that the cost of building science parks in these countries ranges from USD 35-60 million (Poland) to USD 3-5 billion (United States of America). Particular attention is paid to the features of the architectural and planning organization of science parks abroad and in Ukraine. The design proposals of scientific parks, developed for Zaporizhzhia and Kyiv, are presented as model guidelines for use in Donbass. Building on the results of the study of world experience, as well as project proposals for its implementation in Ukraine, it was concluded that the creation of science parks in the Donetsk and Lugansk regions can be considered as an effective tool for innovative renewal and structural restructuring of the regional economy. To enhance the influence of science parks on innovation processes in the studied regions and Ukraine as a whole, proposals were made to amend and supplement the laws of Ukraine "On Science Parks", "On Amendments to Certain Laws of Ukraine Regarding the Activation of Science Parks". The results of the study can be used by the government and the relevant ministry of Ukraine when justifying the choice of models for future science parks in Donbass, their location, specialization, and construction costs.

Exchange Rate Depreciation

Pakistan's local currency has been devalued during different exchange regimes, which may substantially affect energy consumption and CO2 emissions. Therefore, this study investigates the effects of exchange rate depreciation on Pakistan's CO2 emissions and energy consumption from 1990–2018. We apply the nonlinear autoregressive distributed lag (ARDL) cointegration approach for the empirical analysis and found that exchange rate depreciation increases CO2 emissions and energy consumption in both the short and long runs. These results suggest that currency devaluation has an expansionary effect which enhances economic growth at the cost of high energy consumption and CO2 emissions. Therefore, the government needs regulations along with an exchange rate policy to control CO2 emissions. Moreover, the government should search for alternate energy resources such as renewable energy resources that meet the country's energy needs and mitigate CO2 emissions.

The Impact

The main target of climate change policies in the majority of industrialized countries is to reduce energy consumption in their facilities, which would reduce the carbon emissions that are generated. Through this idea, energy management plans are developed, energy reduction targets are established, and energy-efficient technologies are applied to achieve high energy savings, which are environmentally compatible. In order to evaluate the impact of their operations and investments, companies promote measures of performance in their energy management plans. An integral part of measuring energy performance is the establishment of energy baselines applicable to the complete facility that provide a basis for evaluating energy efficiency improvements and incorporating energy performance indicators. The implementation of energy management systems in accordance with the requirements of ISO Standard 50001 is a contribution to the aim and strategies for improving cleaner production in industries. This involves an option for the industry to establish energy benchmarks to evaluate performance, predict energy consumption, and align production with the lowest possible consumption of primary and secondary forms of energy. Ultimately, this goal should lead to the manufacturing of cleaner products that are environmentally friendly, energy efficient, and are in accordance with the global environmental targets of cleaner manufacturing. This paper discusses an alternative for establishing energy baselines for the industrial sector in which several products are produced from a single raw material, and we determined the energy consumption of each product and its impact on the overall efficiency of the industry at the same time. The method is applied to the plastic injection process and the result is an energy baseline (EBL) in accordance with the requirements of ISO 50001, which serves as a reference for determining energy savings. The EBL facilitates a reduction in energy consumption and greenhouse gas emissions in sectors such as plastics, a sector which accounts for 15% of Colombia’s manufacturing GDP.

Biomass is doubtless a very significant source of renewable energy being worldwide abundant with high energy potential. This paper deals with assessment energy consumption at especially grinding and briquetting processes, which should result in essential economy of energy at solid biofuel production. Various types of raw materials were used at the experiment such as hemp (Cannabis sativa L.) biomass, two species of Miscanthus (Miscanthus sinensis, Miscanthus x gigantheus) and apple wood biomass. These materials were dried, grinded and pressed by piston press having pressing chamber diameter of 65 mm. Materials were grinded into three fractions (4 mm, 8 mm and 12 mm). Material throughput (kg.h-1) and energy consumption (kWh.t-1) were registered. As to results: the highest throughput at both grinding cases as well as briquetting was found at apple wood biomass; however the energy consumption during briquetting of apple wood was relatively high. The worst results concerning throughput and energy consumption (especially at briquetting) were found at hemp biomass. Nevertheless, briquettes made of hemp had the best mechanical durability. Both Miscunthus species (herbaceous biomass) have very similar parameters and showed quite good relation between throughput and energy consumption at the used machines.

The subject of the research is the introduction of artificial intelligence as a technological innovation into the Russian economic development. The relevance of the problem is due to the fact that the Russian market of artificial intelligence is still in the infancy and the necessity to bridge the current technological gap between Russia and the leading economies of the world is coming to the forefront. The financial sector, the manufacturing industry and the retail trade are the drivers of the artificial intelligence development. However, company managers in Russia are not prepared for the practical application of expensive artificial intelligence technologies. Under these circumstances, the challenge is to develop measures to support high-tech projects of small and medium-sized businesses, given that the technological innovation considered can accelerate the development of the Russian economy in the energy sector fully or partially controlled by the government as well as in the military-industrial complex and the judicial system.The purposes of the research were to examine the current state of technological innovations in the field of artificial intelligence in the leading countries and Russia and develop proposals for improving the AI application in the Russian practices.The paper concludes that the artificial intelligence is a breakthrough technology with a great application potential. Active promotion of the artificial intelligence in companies significantly increases their efficiency, competitiveness, develops industry markets, stimulates introduction of new technologies, improves product quality and scales up manufacturing. In general, the artificial intelligence gives a new impetus to the development of Russia and facilitates its entry into the five largest world’s economies.

In the mountainous canton Grisons, much visited by tourists, the forest has always had an important role to play. New challenges are now presenting themselves. The article goes more closely into two themes on the Grisons forestry agenda dominating in the next few years: the increased use of timber and climate change. With the increased demand for logs and the new sawmill in Domat/Ems new opportunities are offered to the canton for more intensive use of the raw material, wood. This depends on a reduction in production costs and a positive attitude of the population towards the greater use of wood. A series of measures from the Grisons Forestry Department should be of help here. The risk of damage to infrastructure is particularly high in a mountainous canton. The cantonal government of the Grisons has commissioned the Forestry Department to define the situation concerning the possible consequences of global warming on natural hazards and to propose measures which may be taken. The setting up of extensive measurement and information systems, the elaboration of intervention maps, the estimation of the danger potential in exposed areas outside the building zone and the maintenance of existing protective constructions through the creation of a protective constructions register, all form part of the government programme for 2009 to 2012. In the Grisons, forest owners and visitors will have to become accustomed to the fact that their forests must again produce more wood and that, on account of global warming, protective forests will become even more important than they already are today.

Background: Bioactive compounds from various natural sources have been attracting more and more attention, owing to their broad diversity of functionalities and availabilities. However, many of the bioactive compounds often exist at an extremely low concentration in a mixture so that massive harvesting is needed to obtain sufficient amounts for their practical usage. Thus, effective fractionation or separation technologies are essential for the screening and production of the bioactive compound products. The applicatons of conventional processes such as extraction, distillation and lyophilisation, etc. may be tedious, have high energy consumption or cause denature or degradation of the bioactive compounds. Membrane separation processes operate at ambient temperature, without the need for heating and therefore with less energy consumption. The “cold” separation technology also prevents the possible degradation of the bioactive compounds. The separation process is mainly physical and both fractions (permeate and retentate) of the membrane processes may be recovered. Thus, using membrane separation technology is a promising approach to concentrate and separate bioactive compounds. Methods: A comprehensive survey of membrane operations used for the separation of bioactive compounds is conducted. The available and established membrane separation processes are introduced and reviewed. Results: The most frequently used membrane processes are the pressure driven ones, including microfiltration (MF), ultrafiltration (UF) and nanofiltration (NF). They are applied either individually as a single sieve or in combination as an integrated membrane array to meet the different requirements in the separation of bioactive compounds. Other new membrane processes with multiple functions have also been developed and employed for the separation or fractionation of bioactive compounds. The hybrid electrodialysis (ED)-UF membrane process, for example has been used to provide a solution for the separation of biomolecules with similar molecular weights but different surface electrical properties. In contrast, the affinity membrane technology is shown to have the advantages of increasing the separation efficiency at low operational pressures through selectively adsorbing bioactive compounds during the filtration process. Conclusion: Individual membranes or membrane arrays are effectively used to separate bioactive compounds or achieve multiple fractionation of them with different molecule weights or sizes. Pressure driven membrane processes are highly efficient and widely used. Membrane fouling, especially irreversible organic and biological fouling, is the inevitable problem. Multifunctional membranes and affinity membranes provide the possibility of effectively separating bioactive compounds that are similar in sizes but different in other physical and chemical properties. Surface modification methods are of great potential to increase membrane separation efficiency as well as reduce the problem of membrane fouling. Developing membranes and optimizing the operational parameters specifically for the applications of separation of various bioactive compounds should be taken as an important part of ongoing or future membrane research in this field.
