Inefficient and non-environmentally friendly absorbent production can lead to much resource waste and go against low carbon and sustainable development. A novel and efficient Mg-Fe-Ce (MFC) complex metal oxide absorbent of fluoride ion (F−) removal was proposed for safe, environmentally friendly, and sustainable drinking water management. A series of optimization and preparation processes for the adsorbent and batch experiments (e.g., effects of solution pH, adsorption kinetics, adsorption isotherms, effects of coexisting anions, as well as surface properties tests) were carried out to analyze the characteristics of the adsorbent. The results indicated that optimum removal of F− occurred in a pH range of 4–5.5, and higher adsorption performances also happened under neutral pH conditions. The kinetic data under 10 and 50 mg·g−1 were found to be suitable for the pseudo-second-order adsorption rate model, and the two-site Langmuir model was ideal for adsorption isotherm data as compared to the one-site Langmuir model. According to the two-site Langmuir model, the maximum adsorption capacity calculated at pH 7.0 ± 0.2 was 204 mg·g−1. The adsorption of F− was not affected by the presence of sulfate (SO42−), nitrate (NO3−), and chloride (Cl−), which was suitable for practical applications in drinking water with high F− concentration. The MFC adsorbent has an amorphous structure, and there was an exchange reaction between OH− and F−. The novel MFC adsorbent was proven to have higher efficiency, better economy, and environmental sustainability, and be more environmentally friendly.

Strategic Context

The strategic context of the European Green Agreement for Ukraine analyzed in the article. Ways for developing the process of formation the tasks and measures for the second and third stages of implementation the “Energy Strategy of Ukraine until 2035: security, energy efficiency, competitiveness” were elaborated. The strategic priorities of Ukraine in the field of energy efficiency, energy security and energy saving identified due to the contemporary trends and prospects for EU development in the direction of energy efficiency and energy saving. Moreover, these priorities considering the European integration orientation of Ukraine. The main elements of the European Green Agreement, the scope of EU policy on its implementation are outlined. The provisions of “Energy Strategy of Ukraine until 2035: security, energy efficiency, competitiveness” correlated with the provisions of the European Green Agreement. The necessity of formation the priorities and measures of strategy on the basis of concepts of energy efficiency, energy safety and sustainable development is substantiated. It is substantiated that the existing legislative and regulatory support in the field of nature management and environmental protection is insufficient and doesn’t correspond to modern economic and social situations. Moreover, external and internal threats to the strategy implementation have been identified. The algorithm for the formation and implementation of the energy security and energy efficiency strategy has been developed. The main directions of structural restructuring of the economy and placement of productive forces are worked out within the framework of the strategy due to the requirements of sustainable development and energy security. It was grounded that. The innovative direction of development should be decisive and based on active use of knowledge and scientific achievements, stimulation of innovative activity, creation of favorable investment climate, renewal of production means, formation of high-tech activities and branches of economy. Growth based on attracting investment in the use of renewable energy sources, in environmentally friendly production and “green” technologies.

Lightweight frame structures become increasingly popular in housing. They are used in single-, as well as multifamily, residential buildings. Such a tendency is in the line with sustainable development and the need for energy conservation. Lightweight frame partitions provide a certain comfort of life and remain environmentally friendly. However, they are tricky in terms of acoustics. Different factors and technical details influence their sound insulation. The paper presents the analysis of the acoustical effects resulting from different layers used on lightweight frame floors. Airborne, as well as impact sound insulation, have been considered, based on the results of laboratory measurements according to ISO 10140 standard.

The Impact

This paper describes a group activity concerning the topic of climate change, designed to introduce the concepts of sustainable development into a Robotic Engineering degree. The purpose of this activity was to make students reflect about the impact of their work on the planet as future engineers by asking them to design an environmentally friendly robot that also integrated social and economic aspects, covering the three dimensions of sustainability in this way. Students were surveyed in order to study different aspects of their commitment, attitudes, practices, and motivation towards sustainability. In addition to the overall analysis of the survey, three specific studies were carried out with the aim of comparing the responses of different population groups: (i) Students who completed the proposed assignment and students who did not, (ii) female and male students, and (iii) roles played in the assignment. The results of the analysis revealed the high commitment of the students with respect to sustainability, but also a lack of active participation and awareness of their impact as future engineers. The activity was not only a way to introduce sustainability concepts, but in many cases, it also became a motivation for the participants, especially for the female students.

In order to meet the requirement of sustainable development, building materials are increasingly environmentally friendly. They can be partially or fully bio-based or recycled. This paper looks at the development of fully bio-based composites where agro-resources are valued as bio-based aggregates (hemp) and as binding materials (wheat). In a previous work, a feasibility study simultaneously investigated the processing and ratio of wheat straw required to ensure a gluing effect. In this paper, three kinds of hemp-straw composites are selected and compared with a hemp-polysaccharides composite. The gluing effect is analyzed chemically and via SEM. The developed composites were characterized multi-physically. They showed sufficiently high mechanical properties to be used as insulating materials. Furthermore, they showed good thermal performances with a low thermal conductivity (67.9–69.0 mW/(m · K) at 23 ° C, dry).

t. Theoretical approaches to the sustainable development of cities and towns in the Arctic zone of the Russian Federation are considered. As such approaches, the concept of a «green» smart city, the concept of thermal stress in an Arctic city, the concept of a «winter city», the concept of an Arctic base city, the concept of developing coastal Arctic settlements based on the principles of the blue economy (the economy of marine nature management and coastal zones), the concept of ensuring the vital activity of Arctic cities, etc. are analyzed. In addition, the contribution of Arctic cities to environmental pollution and climate change, socio-economic and demographic development of the Arctic zone is analyzed. The development of Arctic cities, especially single-industry towns and settlements is considered in the context of the Republic of Karelia, the Murmansk, Arkhangelsk Regions, the Komi Republic, the Chukotka Autonomous Okrug, the Republic of Sakha (Yakutia) and the Krasnoyarsk Territory. The main directions of sustainable development of Arctic cities and towns are substantiated from the point of view of achieving the target indicators of the “Strategy for the development of the Arctic zone of the Russian Federation and ensuring national security for the period up to 2035”.
