“…Therefore, it will be necessary to accept action plans for the recovery capacities at the level of autonomies as soon as possible. The task is also to find a way to solve non-recycled communal waste in the sense of the waste economy hierarchy [43].…”

The circular economy and efficient use of resources gained importance in the context of sustainable development. The paper aims to evaluate the development of landfilling in Slovakia. The next goal is to assess the trend in compared with the EU’s situation. The presented research presents a continuation of previous research in the area of waste recycling in Slovakia, pointing to the waste and landfilling, which is deserving of analysis from a long-term perspective. The research is carried out via data collection at the EU level by recording continuously published values. The paper’s results are processed in statistical software. Considering regional development, landfilling in Slovakia is followed up according to the geographical units of the entire country. The results shown here show that a higher recycling capacity is required and Slovakia should decrease its level of landfill. Such results can be used in the waste treatment area, protection of the living environment and sustainable development of regions.

“…They also reached conclusions about the major modifications to the U.S. electricity infrastructure needed to achieve this wide-scale electrification. The importance of the carbon footprint of the electricity network was also highlighted in [7]. Schoeneberger et al [8] stressed the necessity to take into account the environmental content of the grid mix to appropriately quantify the savings.…”

“…In addition, the proposed approach needs to be combined with an economic assessment of electrification to ensure its feasibility and, above all, the motivation of industries to make this transition. Jovet et al [7] proposed an approach for assessing the economic feasibility of switching from gas to electricity. To go further, it would be interesting to develop this approach for different types of electricity mixes in different geographical contexts to extend the analysis.…”

Most studies on industrial heat decarbonization by electrification focus on energy and greenhouse gas emissions. However, there are additional potential environmental impacts to be considered to make a fair comparison. The aim of the proposed work is therefore to highlight the benefits and drawbacks of switching to electricity, using life cycle assessment (LCA) methodology to explore more environmental issues. In addition, in order to evaluate the environmental sustainability of this transformation, the LCA results are compared with sustainability thresholds defined with two different methods, on a global scale using the “sustainable levels” concept. The first method is based on the current environmental impacts of industrial processes, while the second considers the economic added value. Industrial heat production levels for the Danish and French food industries are used as case studies. The results show a large number of environmental trade-offs associated with electrification, some of which are leading to unsustainable levels. Sustainability thresholds based on economic added value ensure a fairer distribution between sectors, in particular by preventing the most virtuous sectors and processes from being penalized.

“…The payback time (PBP) and the levelized cost of energy (LCOE) were calculated for the economic feasibility evaluation. The payback time was used as a metric based on Jovet et al assessment of the decision-making in industrial waste heat recovery long-term project planning and the same calculation method was used in this study [24]. The calculation of LCOE was based on the method described in Lotfi et al on the evaluation of LCOE for microgrids [25].…”

As demand for data centers (DC) has increased rapidly, so has their electricity consumption. Cooling DCs is essential to maintain optimal temperatures for the operation of servers and equipment. The consequence of the cooling process is that most of the electricity consumed in DCs, including cooling, is eventually dissipated as heat that is released into the atmosphere without any useful application. Recovering and reusing waste heat offers a sustainable solution to reduce primary energy consumption and minimize the environmental impact. Using waste heat from DCs to heat buildings can significantly improve the energy efficiency and environmental sustainability of DCs. Therefore, this research analyzes the existing potential of waste heat recovery from data centers in Latvia and proposes a system dynamic modelling approach for evaluation of the future impact of waste heat on the national heat supply. The overall waste heat generated by DCs in 2022 was 51.37 GWh at a temperature of 65 °C. By 2050, the total heat energy production potential from DCs will increase to 257 GWh, with 201 GWh being utilized.
