Drawing on a structured bibliometric review approach and advanced bibliometric methods, the analysis covers 278 peer-reviewed articles indexed in the Web of Science database. This study explores how research on the SDG–renewable energy nexus has evolved over time, highlighting publication trends, geographical patterns, influential journals and authors, and the intellectual structure of the field, with particular attention to developments observed after 2022. The results show a rapidly growing and increasingly interdisciplinary body of research in which renewable energy systems are consistently framed as core elements of sustainable development strategies, energy transition pathways, and policy-relevant frameworks. Beyond descriptive mapping, the study provides a mechanism-oriented interpretation of thematic clusters, explicitly linking renewable energy research trajectories to specific SDGs and their systemic interactions. By identifying dominant research themes, emerging directions, and existing research gaps, this review provides strategic insights that can support future academic research and inform policymakers and energy stakeholders involved in steering the transition toward sustainable energy systems. 2026-01-01T00:00:00Z http://195.117.226.27:8080/xmlui/handle/123456789/899 The State and Development Directions of Polish Waste-to-Energy Plants in Improving R1-Based Energy Recovery Performance Banaś, Marian; Pająk, Tadeusz; Wróbel, Wojciech; Ciuła, Józef The paper presents an analysis of the status and development trends of Polish Waste-to-Energy (WtE) installations in the context of improving the level of energy recovery measured by the R1 indicator of the Waste Framework Directive (R1 is a regulatory indicator of the R1/D10 classification, not the thermodynamic efficiency of the installation). Based on the standardised annual operating energy balances of six mature municipal waste incineration plants from 2020 to 2024 and partial data for 2025, electricity and heat production, auxiliary media consumption and waste fuel parameters were compared, and R1 was calculated in the Ep, Ef, Ew and Ei systems. The R1 values were then compared with heat collection conditions and modernisation implementations (integration with the heating network, exhaust gas condensation, advanced control/predictive algorithms), treating the ‘before/after’ comparisons as an observational assessment, without inferring strict causality. The average R1 for the facilities studied in 2020–2024 was 0.864, with the highest values recorded for installations in Kraków (R1 = 1.123 in 2024). The results indicate that a high and growing R1 is primarily associated with cogeneration and stable heat management in district heating systems, and that upgrades aimed at additional heat recovery and process stabilisation can further support this trend, in line with the ‘energy efficiency first’ principle. A novelty of the study is the standardised, long-term benchmarking of full-scale data for six installations using a uniform R1 methodology. 2026-01-01T00:00:00Z http://195.117.226.27:8080/xmlui/handle/123456789/898 Effectiveness of spin coating quantum dots deposition process onto mesoporous titanium dioxide for photovoltaic application Kwaśnicki, Paweł; Gronba-Chyła, Anna; Generowicz, Agnieszka; Ciuła, Józef; Duriagina, Zoia; Koval, Viktor; Tepla, Tetiana; Herbut, Piotr; Mucha, Zbigniew; Mańkowska, Dorota The aim of this work was to present an effective method for deposition onto a conductive material covered by a thin film on a glass surface using the spin coating technique. The TiO2 layer, consisting of 99% anatase particles (~20 nm diameter), was applied via screen printing to an estimated thickness of ~5 μm onto TCO-coated glass (NEC A7). QDs were deposited using spin coating with controlled parameters: time 90 s, rotational speed 4000 rpm, and acceleration A=100 rpm/s. Three types of colloidal QDs dispersed in toluene were utilized: ZnCuInS/ ZnS (max. em 530 nm ) ZnCuInS/ZnS and (max. em 700 nm), both at 1 g/ml concentration, applied in volumes of 250 μl and 500 μl; and CdS (max. em 460 nm) at 0.5 g/ml concentration, applied in volumes of 500 μl and 1000 μl. Selected samples underwent post-deposition annealing at 250 °C for 15 minutes. Surface morphology was characterized using Scanning Electron Microscopy (SEM) in the backscattered electron (BSE) detector configuration, while optical properties were assessed using double-beam spectrophotometer. In conclusion, the results confirm the effectiveness of the spin coating technique for QDs deposition onto TiO2 layers, validating its potential to enhance optoelectronic performance through improved light absorption and charge separation dynamics crucial for QD-sensitized solar cell applications. 2026-01-01T00:00:00Z http://195.117.226.27:8080/xmlui/handle/123456789/851 Assessment of the Possibility of Implementing a Circular Economy by Environmental Evaluating the Life Cycle of Products Derived from Bulky Municipal Waste Generowicz, Agnieszka; Gronba-Chyła, Anna; Godula, Piotr; Kulczycka, Joanna; Lewandowska, Anna; Dorosz, Aneta; Ciuła, Józef; Kwaśnicki, Paweł Current wood waste recycling processes need to be improved to prioritize ma- terial recovery over energy recovery by cascading the use of wood waste and limiting as much as possible non-recyclable batches that may contain even partially highly contam- inated grade C wood and/or Medium Density Fiberboard. In the presented research, a life cycle assessment has been carried out for a new product recovered from bulky waste. The Environmental Footprint 3.1 (adapted) method has been used to assess the potential environmental impact. The results may support a quality assessment of new products undertaken from the perspective of the circular economy and environmental management in the waste sector. The study aimed at the identification of environmental hotspots in the life cycle of the secondary wooden blocks (from cradle to market analysis). Bulky waste was subjected to recovery and recycling processes (a laboratory scale), and by adding starch and water a new product was obtained. The study has demonstrated that the production of blocks has the greatest impact on the life cycle in the following categories: Resource use, fossils (24%), Climate change (23.9%), Eutrophication, freshwater (13.3%), and Resource use, minerals and metals (11.8%). This is due to the high electricity consumption of electric- ity by equipment and machinery used for the processing of waste and the fabrication of the blocks. 2025-01-01T00:00:00Z
