ECO-ORIENTED MANUFACTURING TECHNOLOGIES IN THE PROFESSIONAL TRAINING OF TILERS

The relevance of this article is dictated by the acuteness of the environmental pollution issue, especially from the construction sector, which presents a challenge both for Ukraine and globally. One of the solutions to this problem is the implementation of green building, which involves the use of environmentally friendly materials, innovative waste-free and low-waste technologies, alternative energy sources, waste recycling, etc. This necessitates new, ecologically oriented approaches in the training of qualified construction workers, particularly tile setters. Objective: Based on global and national experience in green building, this study aims to investigate the issue of training tile setters in Ukraine using eco-oriented technologies and to develop recommendations for improving the process of integrating these technologies into educational curricula and programs. Methods: Analysis of domestic and foreign sources on ecological education and green building, empirical research on the practice of applying ecotechnologies by tile setters in Ukraine. Results: The essence of eco-oriented professional training is revealed, the foreign and national experiences in green building are analyzed; eco-oriented technologies for tile setters are examined; the main ecological requirements for building materials and technologies for tiling works are disclosed; corresponding recommendations for the use of eco-oriented technologies in the professional training of future tile setters are prepared. Conclusions: Eco-oriented professional training must become an integral part of the professional competence of tile setters, bringing changes both to the content and methods of education. For instance, during tiling works, environmentally friendly hydro insulation membrane materials are used; powerful construction companies that conduct eco-certification of their products have emerged; the use of mastics and adhesives based on dry building mixtures reduces construction waste and, consequently, soil pollution at the construction site; more precise laser measuring devices are increasingly used in tiling works. Therefore, in training tile setters, attention should be paid to studying modern green technologies. The importance of developing normative legal acts on eco-certification of building materials and technologies, and subsequently buildings, is substantiated. It is recommended to revise the National Standard of Professional Education for the profession of tile setter, considering ecological requirements, and for teachers of vocational education institutions to pay special attention to forming ecological competence in future tile setters.

Moving towards Greener Road Transportation: A Review

Road transportation accounts for about 20% of the total GHG emissions in the EU. Nowadays, the substitution of conventional fossil fuel-based ICEs with electric engines, or their hybridization, operating along with Energy Storage Systems, seems to be the most appropriate measure to achieve reductions in both fuel consumption and GHGs. However, EVs encounter crucial challenges, such as long charging time and limited driving range. Hence, the transition to the mass adoption of EVs requires considerable effort and time. However, significant steps have been taken in the hybridization of road vehicles, with the aid of renewables and energy recovery/saving systems. In this context, this paper presents a comprehensive literature review of modern green technologies for GHG reduction that are applicable to road transportation, such as on-vehicle energy harvesting and recovery (e.g., thermal, kinetic, etc.) systems and the incorporation of RES into EV charging stations. The impact of road vehicles on the environment is discussed in detail, along with the EU roadmap towards the decarbonization of transportation. Next, methods and techniques for fuel consumption and GHG reduction are systematically presented and categorized into on-vehicle and off-vehicle ones. Finally, a future outlook on more environmentally friendly road transportation is presented.

Improving the gravity-vortex micro-hydroelectric power station efficiency by ensuring an acceptable value of the water inlet canal’s twist angle

Micro-water energy is a promising alternative energy source that produces electricity in remote areas, separated from the main electricity grid. In this research work, the method of increasing the efficiency of gravity-vortex micro-hydroelectric power station operating in low-pressure water flows through the twist angle of the inlet channel of the basin is presented. Gravity-vortex micro-hydroelectric power station is a new modern green technology as an alternative or renewable energy source. The advantage of this method of electricity production is that it is possible to produce electricity at a low pressure, i.e. starting from a pressure of 0.7 meters. In order to increase the initial speed of the water entering the cylindrical basin, the flow fields of the water flow inside the basin in the range of 0-90 degrees of the inlet channel twist angle were numerically simulated using the ANSYS Fluent software. As a result of the study, the parameters of the influence of the flow velocity vector on the flow field were studied.

Extraction of rare earth elements from a South American ionic clay

Ionic clays, formed by the natural weathering of REE-bearing minerals and the adsorption of the resulting liberated REE ions onto the clay surface, are an important resource for critical rare earth elements (REEs). Here, a two-step desorption process using ammonium sulfate with active pH adjustment using sulfuric acid was developed to extract REEs from a South American clay. The desorption process was optimized using response surface methodology approach and the optimum operating conditions were determined to be 0.15 mol/L ammonium sulfate, pH 3, liquid to solid ratio of 3/1, and 25 °C with 20 min residence time. It is shown that this ionic clay is significantly different from previously reported clays, e.g., from southern China, as it consists of three modes of REEs, including ion-exchanged REEs physically adsorbed on the clay surface, hydrolyzed REEs chemically adsorbed on the clay surface, and mineralized (non-desorbable) REEs within the clay. Mechanistic investigations through progressive acidification during desorption and adsorption isotherms show that REE desorption/adsorption occurs due to the combined action of physical ion exchange adsorption and surface complexation chemical adsorption, with their relative importance depending on the pH of the system and the amount of sulfate anions present within the solution. This work supports overall efforts to utilize ionic clays as a relatively new resource for REEs to empower the development and adoption of modern green technologies such as wind turbines and electric vehicles.
