As a result, the implementation of measures to protect the atmosphere (the use of innovative technologies in the introduction of dust and gas cleaning equipment, the conversion of cars to gaseous fuel, the renewal of rolling stock, the implementation of the state program to reduce emissions), the stabilization of the environment is observed. It is necessary to carry out technical re-equipment of key sectors of the economy, the introduction of new technologies, as well as the stabilization and reduction of emissions of pollutants into the atmosphere. It is recommended to take additional measures to ensure that the amount of pollutants released into the atmosphere as a result of the operation of the facility does not exceed the permissible level, to install dust-collecting equipment that captures dust with high efficiency (up to 99.5%).

Recently, the Japanese government has announced the national objective of turning the economy of Japan carbon-neutral by 2050. This declaration has therefore enhanced the imperativeness of replacing the use of unclean energy with cleaner alternatives so that the carbon-neutrality agenda can be attained in due course. Against this backdrop, this study aims to assess whether enhancing government investments in research and development for developing clean energy can help Japan curb its carbon dioxide emission figures. In addition, the analysis also controls for the environmental effects of clean electricity output, economic growth, international trade, financial globalization, and urbanization on Japan's carbon dioxide emission figures. The cointegration test results confirm long-run relationships between all these variables. Besides, the regression results showed that scaling-up research and development-related investments for clean energy development reduces carbon dioxide emissions only in the long run. Similar emission-inhibiting impacts are also evidenced to be associated with greater output of clean energy-fired electricity. Moreover, it is also observed that higher clean energy development-related investments play a mediating role in amplifying the carbon dioxide emission-reducing effects of clean electricity generation in the long run. In addition, economic growth is seen to dampen environmental quality by triggering higher emissions of carbon dioxide both in the short and long run. Simultaneously, enhancing openness to international trade and greater urbanization is found to boost the carbon dioxide emission figures of Japan. However, an influx of foreign direct investments is not observed to influence carbon dioxide emissions in Japan, neither in the short run nor in the long run. Accordingly, concerning the achievement of carbon neutrality goal by 2050, these findings emphasize the importance of boosting clean energy development-related investments, increasing clean electricity output, greening economic activities, reducing the trade of unclean commodities, adopting environmentally sustainable urbanization policies, and facilitating the influx of clean foreign direct investments within the Japanese economy.

Sustainable development policies for achieving net-zero emissions require understanding the factors that influence carbon emissions. Capitalizing on the limitations of the existing literature, this study applies the quantile-on-quantile approach to investigate economic globalization's impact on carbon emissions in Australia for 1970-2018. The results from the quantile-on-quantile revealed a positive feedback linkage between globalization and carbon emissions at all quantiles. The results further indicated that while there is a positive feedback linkage between economic growth and carbon emissions at most quantiles, a positive feedback interconnection exists between carbon emissions and coal consumption at all quantiles. As a robustness check, we employed the quantile regression test, and the results from quantile regression are consistent with the findings from the quantile-on-quantile approach. The consistency of the results suggests that these study findings are reliable and suitable for informing policies that seek to address carbon emissions in Australia. The policy implications for Australia are discussed.

The article discusses development of recycling technologies of cabling and wiring products with justification for the relevance of the cable waste use in the process as part of the closed technological cycle of cabling and wiring products manufacture. Sources of waste generation are analysed. Issues of uninterrupted operation and reliability of technological equipment, efficiency of the recycling process and problems of the development of processing technologies in cable production are highlighted.

Global climate change is undoubtedly one of the main threats to the world community among existing environmental problems. This problem has a particularly severe impact on water resources. Changes in hydrological processes or flows in river basins directly or indirectly affect the dynamics of changes in gross domestic product (GDP) in this region. Chirchik basin provides about 16% of GDP of the republic, and more than 70% of water resources are used for irrigation of crops [1-5]. For this reason, any factors affecting hydrological processes and flow dynamics in the river basin, especially climate change, immediately affect all aspects of life in the region, including the social level of society and economic stability. Assessing the impact of climate differences on river basin flow dynamics is important for ensuring sustainable agricultural productivity for river basins in the future, as well as reducing the ecological and environmental impacts of climate change. This situation calls for urgent and concerted action in several areas: technology, infrastructure, politics, economy, ecology and environmental protection. The article assessed the impact of changes in precipitation intensity on stream dynamics based on the Global Circulation Model (GCM) coordination scenarios, RCP4.5 and RCP8.5 for the years 2030, 2050 and 2070 using the delta approach method. The results of the study provided strong evidence for changes in stream dynamics in the Chirchik basin for the near and far future.

This article is devoted to the analysis and role of modern information and communication technologies and systems in the water sector, and the relevance and necessity of using information systems in water use to improve the ameliorative state of irrigated land is justified, which will solve problems such as improving the system for collecting information means of preparing data oriented to a new information technology, introducing an integrated organization of information flows, reduction of resources for data processing capacity, development of decision-making procedures for the formation of options for the development of water use, etc. The task of the most efficient use of water resources and improvement of land ameliorative condition is to obtain the maximum amount of products at lower cost. The assessment of water use efficiency is made not by their value, but by the effect obtained by the water consumer.

This study examines the long-term relationship between carbon emissions and a number of researchers engaged in Research and Development (R&D), economic development, foreign capital inflows, renewable energy and population growth in 26 countries between 1995 and 2015. Pedroni’s panel cointegration test confirms the cointegrating relationship between the variables. Long-term elasticities are derived from FMOLS regression. Researchers in R&D and renewable energy are negatively and significantly related to carbon emissions. There is a positive and significant long-term relationship between GDPs per capita and CO2 and between the FDI and CO2. Dumitrescu and Hurlin’s panel causality test revealed unidirectional causality running from economic development to carbon emissions and feedback hypotheses between the FDI and CO2 and between renewable energy and CO2.

The synthesis of new cation-exchanger based on local raw materials for the extraction of copper from copper-containing solution investigated. A review of the literature regarding the problem of ion exchange method and the use of mine wastewater treatment process is presented. Sorption selectivity of Cu2+ ions by cation exchanger in the H-and Na-forms from dilute solutions was studied in the target concentration range 90 mg/dm3 and 5,49 g/ dm3. The full dynamic exchange capacity calculated. The cation exchanger analyzed with consideration for IR spectroscopic, chemical analysis, and scanning electron microscopic data. Quantum-chemical calculations performed that synthesized cation-exchanger stable complexes with Cu2+ ions. Obtained cation exchanger due to excellent behavior recommended removing copper ions from wastewater in the mine industry.
