Circular economy means smarter use of resources. The circular economy is built using sustainable economic models based on innovation and technology to allow the repeated use of the same resources. Achieving a zero carbon footprint on the natural environment by 2050. is the top priority. This would only be possible if the world moves towards a circular economy, and this is one of the highlights of the Green Deal, while also aiming to increase the competitiveness of the economy.

    • AI-driven strategies for category management rofitability

      pg(s) 14-16

      Category Management (CM) is undergoing a transformation thanks to artificial intelligence (AI). AI automates tasks such as data analysis, market segmentation, and demand forecasting, which streamlines and simplifies the work of category managers. It also allows the creation of innovative strategies and campaigns that are relevant to customer needs. This paper focuses on identifying ways in which AI can help to create innovative strategies needed to optimize prices and product lines within category management with the aim to maximize profitability. The paper deals deeper with price optimization, where AI significantly impacts CM. AI analyzes price elasticity and suggests optimal prices for products, which affects the maximization of profitability. Thanks to AI, category managers no longer have to rely on manual analysis and intuition, but they can set prices with much greater accuracy and efficiency. Based on the findings and case studies in the article, the implementation of AI in CM brings companies significant benefits in terms of efficiency, innovation, and profitability. However, it requires strategic planning, investment in technology, and talented people. It is also important to be responsible and ethical when using AI to avoid negative impacts on customers and society.

    • Positioning a holistic approach for integration of renewable energy powered charging stations into a nationwide electrical power distribution system

      pg(s) 17-21

      This paper explores various models of integrating independent Electric Vehicle Charging Stations (EVCSs) into Montenegro’s electricity distribution system (EDS) and energy market. It examines different possibilities by applying a multidisciplinary approach to the EDS integration coupled with market frameworks to form a novel holistic perspective for participations and influences of various stakeholders. The primary goal is to envisage and achieve a more efficient integration of different prosumers models that own and engage independent EVCSs with photovoltaic systems into the EDS and transport infrastructure. This approach is aimed at reducing CO2 emissions, promoting electromobility, engagement of citizens, and facilitating distributed renewable electricity generation at the point of consumption. Through the analysis of each of the three identified prosumer models, we give specifics of the integration within the grid, solar energy exploitation potentials, practical options for energy provisioning during and outside sunny periods etc. Economic, legal, and technical implications are integrated, and recommendations are provided using economic modelling and game theory formulations between the relevant actors and within regulatory provisions to optimize electric mobility in Montenegro.

    • Non-detonating chemical mixture for non-invasive methods of rock breaking

      pg(s) 22-25

      Within the Innovation Project of the Ministry of Science and Technological Development of the Republic of Serbia, researchers of Blasting Center at the University of Belgrade – Faculty of Mining and Geology have developed several different non-detonating chemical mixtures for non-invasive methods of rock breaking. Laboratory and polygon tests gave the satisfactory results and knowledge enough to start the practical experiments in the field. The basis of this innovation is a theoretical assumption that certain chemical mixtures release a large quantity of gases during combustion. If these gases are found in the enclosed space a growing pressure on the walls of the chamber in which combustion takes place will be resulted. If this space is a borehole with good stemming, the rising pressure should be sufficient to break the rock material in which the borehole was drilled. Chemical mixtures developed through the research do not detonate. They represent the generators of borehole pressure made up of oxidants and fuels and the modifiers to adjust the speed of combustion and ignition temperatures. Rock breaking occurs because of progressive increase in pressure. Non-detonating chemical mixtures can be applied in road and railroad construction, demolition works, secondary breaking, rock breaking for foundation, trenching and similar civil construction operations especially in urban areas as well as quarrying of dimension stones. In other words, for different methods of rock breaking where negative effects of blasting should be avoided.

    • The effect of applying a conversion layer by phosphating on the roughness relief of the steel surface

      pg(s) 26-28

      The contribution is focused on the analysis of the surface roughness after applying the conversion layer using phosphating. In the experiment, uncoated deep-drawn steel DC 04 was used as the base material. During the application of the conversion layer, changes in surface roughness were studied with respect to the phosphating time, which was 3, 5 and 10 minutes. The achieved results provide information for other technological operations such as creating joints by gluing, where the correct anchoring of the glue is important for sufficient adhesion to the surface.

    • Exergy analysis of a two-cylinder steam turbine from combined cycle power plant at three operating regimes

      pg(s) 29-32

      This paper presents an exergy analysis of a two-cylinder low power steam turbine from combined cycle power plant at three operating regimes. The highest mechanical power produced in the whole turbine is 6807.24 kW in Operating regime 1. Cylinders of the observed turbine did not have the same operation dynamics in relation to produced mechanical power in all operating regimes. In each operating regime High Pressure Cylinder (HPC) has lower exergy destruction and higher exergy efficiency in comparison to Low Pressure Cylinder (LPC) due to the influence of wet steam which expands through the last LPC stages (water droplets in wet steam increases LPC exergy destruction and decreases LPC exergy efficiency). Whole turbine exergy efficiency is between 51.62% (in Operating regime 2) and 64.98% (in Operating regime 1). This range of exergy efficiencies can be expected for a low power steam turbine. An increase in the ambient temperature decreases exergy efficiency of the whole turbine and both turbine cylinders, regardless of the observed operating regime. The exergy efficiency of the LPC is low in all operating regimes, so any improvements should be based on this cylinder first.
