1. Strategic integration of sustainability, circular economy, and blockchain in Slovenian urban governanceGorazd Justinek, 2025, izvirni znanstveni članek Opis: Slovenia has 12 urban municipalities, each with a sustainable development strategy aligned with the Agenda 2030 framework and valid through 2030. This paper examines how these strategies incorporate emerging technologies, particularly blockchain, and innovative sustainability concepts such as the circular economy. Achieving the goals of Agenda 2030, especially transitioning to a circular economy, requires doubling energy efficiency by 2030. While blockchain and the circular economy have often been studied separately, this research explores their intersection within the context of urban sustainability. The study applies qualitative content analysis to the official development strategies of all 12 urban municipalities. This analysis is complemented by semi-structured interviews with senior officials from the Ministry of the Environment, Climate and Energy, and the Vice Mayor of Ljubljana, providing institutional perspectives on strategic priorities and implementation logic. This is the first comprehensive analysis of how Slovenian urban municipalities address the interconnected themes of sustainability, circular economy, and blockchain technology. The findings contribute to academic discussions and offer practical recommendations to enhance innovation in urban sustainability planning

2. Circular economy implementation in the electric and electronic equipment industryMargaret Zoka, Romana Korez-Vide, 2025, izvirni znanstveni članek Opis: The circular economy (CE) encourages sustainability by shifting towards business models that prolong resource use. The quantity of waste generated by electric and electronic equipment (WEEE or e-waste) is rapidly rising and is one of the fastest-growing waste streams. Our paper explores the awareness, benefits, barriers, incentives, and implementation of CE in the electric and electronic equipment (EEE) industry in Slovenia and Croatia. In the theoretical section, we review the existing literature on CE, the EEE industry in both countries, and their policy frameworks for developing CE. Based on primary research through a survey and inferential statistical analysis in the empirical section, we investigate the implementation of CE in the EEE industry in both countries. This paper identifies which CE practices companies in the EEE industry implement, how company size affects CE implementation, how companies evaluate institutional support to CE, and their plans regarding CE. The results highlight some differences between the two countries. Drawing on the empirical findings, we determine key challenges and opportunities for increasing CE adoption in this sector and formulate some European suggestions for policymakers, industry practitioners, and researchers.

6. When technology meets sustainability: microplastic removal from industrial wastewater, including impact analysis and life cycle assessmentJan Puhar, Michael Toni Sturm, Erika Myers, Dennis Schober, Anika Korzin, Annamaria Vujanović, Katrin Schuhen, 2025, izvirni znanstveni članek Opis: Microplastics (MPs) that are ubiquitous in aquatic environments and industrial wastewater streams have been identified as key hotspots of MP contamination. It is significantly more effective to remove MPs at these points before they enter municipal wastewater streams. This study is an environmental assessment of a novel pilot plant for the removal of MPs and the chemical oxygen demand (COD) from wastewater with a high MP contamination from a plastics manufacturer in Germany. MP removal is based on physical–chemical agglomeration–fixation by organosilanes. Formed agglomerates are separated using a belt filter. The COD is removed by an adsorption process. The resulting MP removal was 98.0 ± 1.1% by mass and 99.9987 ± 0.0007% by particle count, while the COD was reduced by 96 ± 2.7%. The system’s sustainability is evaluated using the Life Cycle Assessment methodology, evaluating system construction, operation, and end-of-life considerations. The current pilot plant is also compared to an optimized circular and sustainable upgrade, where drivers of environmental burdens are eliminated and collected MPs are reused. Significant reductions in environmental impact categories are achieved and the global warming potential is reduced by 96%. This study provides a sustainability assessment of a novel technology and circular solution to remove MPs from highly polluted industrial wastewater.

8. Youth awareness and attitudes towards a circular economy to achieve the green deal goalsDamjan Krajnc, Darko Kovačič, Eva Žunec, Kristijan Brglez, Rebeka Kovačič Lukman, 2022, izvirni znanstveni članek Opis: In order to approach a system change towards a circular economy model (CE) in Europe,
the entrepreneurial activities of young people need to be encouraged to achieve the Green Deal (GD)
goals. This article presents the evaluation results of young people’s awareness and attitudes towards
the CE and the GD. The data used in this study was collected by surveying 286 young people from five
European countries. The questionnaire covered four areas: (1) belief, (2) knowledge, (3) competence,
and (4) young people’s ability to deal with the CE. Descriptive and exploratory factor analysis (EFA)
was conducted to analyse the questionnaire on the basic factors that motivate young people to the CE
and GD. A literature review was conducted to identify the main research concepts and connections.
A review included two phases, the first encompassing a search through the Web of Science (WoS)
Core Collection for research papers meaningful for further research, followed by Leximancer analysis.
The analysis showed that young people believe in the principles and priorities of CE but do not
receive enough support to participate and implement the priorities actively. Formal education does
not provide enough knowledge to work in this field actively. They are primarily undecided about
their understanding of the principles of CE. Responses to whether they can implement the project,
business, or entrepreneurial ideas are also uninspiring. Young people do not see themselves as
creators of change towards the CE. However, it is encouraging that they approach the CE from
different angles and show responsible behaviour in everyday life. Young people’s ability to reason,
think, evaluate, connect, and create new solutions for the CE is not enviable. Most respondents did
not comment on their competence in concepts of the GD and CE. It is encouraging to know that they
have already heard about the CE’s goals and action plan. Young people do not show significant skills
in the practical implementation of CE principles. The analysis has shown that young people are
particularly unable to reason, think, and evaluate in an entrepreneurial way when linking the CE
to business opportunities. Relating them to business models and entrepreneurship also seems to be
problematic. As a result, the majority of them are unable to design, develop, and create new business
solutions.

9. A multi-level approach to circular economy progress : linking national targets with corporate implementationJan Drofenik, Tine Seljak, Zorka Novak-Pintarič, 2025, izvirni znanstveni članek Opis: An integrated top-down methodology for assessing and promoting progress towards a circular economy at macro (national) and micro (company) levels is presented. It is based on the MICRON (MIcroCirculaR ecOnomy iNdex) framework developed by Baratsas et al. (2022) for companies. In this paper, it has been extended to enable a consistent assessment for companies and countries. The methodology facilitates the analysis of key categories: energy, emissions, water, materials, and waste. A quantitative analysis of circularity, including a sensitivity analysis, is conducted at the macro level, identifying critical areas and the most influential factors for the circular economy. Based on this analysis, existing national strategies are evaluated, and implementation plans with specific measures are developed. This is followed by micro-level implementation, which involves techno-economic assessment of circular projects. Using this methodology, coordinated improvements in circularity are achieved at all levels. The methodology was tested in Slovenia, where the national circularity index revealed stable performance over five years, averaging slightly above 50 points out of 100. Analysis identified significant improvement potential in areas such as energy and emissions, aligning with the country's focus on decarbonization and energy efficiency in its climate strategies. At the company level, circularity assessments highlighted critical challenges in renewable energy use and overall energy efficiency. The proposed measures showed potential for significantly improving circularity and reducing emissions, while the results provided valuable insights into the economic feasibility of these transitions.

10. Barriers and influencing factors in the implementation of circular economy in Slovenian road transportKristijan Brglez, Mateja Čuček, Andjelko Andy Kober, Rebeka Kovačič Lukman, 2024, izvirni znanstveni članek Opis: The European Union’s commitment to sustainable development, exemplifed by the Green Deal and the United Nations Sustainable Development Goals, highlights the importance of the circular economy, especially for road transport companies. This study examines the current state of circular economy practices in Slovenian road transport through an inquiry of 151 logistic companies. Utilizing principal component analysis, fve key factors infuencing circular economy implementation were identifed: knowledge and competences, company practices, strategies, regional development, and market presence. Additionally, seven barriers were noted: lack of knowledge, fnancial constraints, time limitations, space constraints, limited technology, management issues, and supply chain coordination challenges. Findings suggest that circular practices are often secondary to business proftability, with fnancially stable companies more likely to adopt these practices. Success in circular economy implementation requires investments in innovative technologies, capacity building, and strong management support. Companies in more developed regions tend to adopt circular practices due to better access to knowledge and incentives. These insights provide a foundation for future research, including comparative studies across transport sector in European Union and globally.
