2. Developing a framework for closed-loop supply chain and its impact on sustainability in the petrochemicals industryLobna Tag el Sheikh, Rebeka Kovačič Lukman, 2022, original scientific article Abstract: Companies rely on formulating, implementing, and monitoring strategies in social, environmental and economic aspects to ensure that they achieve their goals and keep abreast of developments related to sustainability requirements. Therefore, our study develops a system to integrate the closed-loop supply chain approach in the petrochemical sector. The research follows the quantitative-based approach by collecting data through a questionnaire directed to employees in the supply chain departments, including 230 questionnaires that were collected. Correlation and structural equation models (SEM) were used. This technique consists of multiple regression analysis and factor analysis and analyses the structural relationship between the underlying structures and the measured variables. The results indicated a significant relationship between the supply chains that have a loop from the following perspectives: economic motivations, customer awareness, environmental legislation, and sustainability. By increasing financial reasons, customer awareness and environmental legislation, sustainability will increase as they all move in the same direction. Therefore, the overall effect of a closed-loop supply chain is positive and significant.
Keywords: closed-loop supply chain, petrochemicals, cost effectivity, product stewardship, multiple regression analysis, factor analysis, sustainability

3. Barriers and influencing factors in the implementation of circular economy in Slovenian road transportKristijan Brglez, Mateja Čuček, Andjelko Andy Kober, Rebeka Kovačič Lukman, 2024, original scientific article Abstract: 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.

6. Closed-loop supply chain and impacts on sustainability, comprehending logistics sustainability capacity building : dialogues, paradoxes and innovationLobna Tag el Sheikh, 2024, doctoral dissertation Abstract: This thesis focuses on creating a framework for evaluating the influence of closed-loop on supply chain performance in the case of petrochemical industry in the Egyptian context, with a focus to test the influence of sustainability on the supply chain performance, to investigate the function of sustainability as a mediator between reverse logistics and supply chain performance, and evaluate the impact of closed-loop supply chains (environmental legislation, customer awareness and economic motivations) on sustainable development. The gathering of primary data helped the current study's goals get accomplished. Surveys are used to gather data to estimate how reverse logistics impacts the effectiveness of the supply chain. The employees of supply chain companies in Egypt received the surveys from the researcher. The study's findings indicate a strong link between sustainability and reverse logistics. Additionally, there is a marginally significant correlation between supply chain performance and sustainability. The outcomes also showed that the closed-loop supply chain has little influence on supply chain efficiency and sustainability. Furthermore, there is a marginally significant association between supply chain effectiveness and reverse logistics. The results also revealed that sustainability has a function in supply chain performance and reverse logistics.

7. Supply chain perspectives for achieving economic growth and environmental sustainabilityRebeka Kovačič Lukman, Kristijan Brglez, Maja Fošner, 2024, other scientific articles Abstract: A resilient supply chain is crucial for economic growth and the well-being of economies. However, it contributes to environmental challenges, such as resource extraction, material usage, climate change and biodiversity. This Special Volume of the Journal of Logistics, Supply Chain, Sustainability, and Global Challenges explores current research directions and challenges while offering solutions for sustainable supply chains. The volume examines existing European policy directives and strategies to comprehensively understand sustainable supply chain requirements. It conducts a content analysis of the current research in the field. The authors present valuable theoretical insights and empirical case studies addressing the interplay between sustainable supply chains, economic growth, and environmental impact mitigation. The papers in this Special Volume highlight the holistic and interconnected nature of the supply chain field and emphasise that there is still significant potential for improving supply chain processes to enhance their sustainability.
Keywords: sustainable supply chains, economic growth, environmental impact, industry 4.0

8. Turizem in blaženje podnebnih sprememb : oblikovanje modela ocene ogljičnega odtisa turistov, ki prenočijo v Sloveniji, in priporočil za zmanjševanje ogljičnega odtisa v slovenskem turizmu2024, scientific monograph Abstract: Pričujoča monografija je rezultat projekta »CRP V7-2128 Podnebne spremembe in trajnostni razvoj turizma v Sloveniji«.

9. A conceptual model for measuring a circular economy of seaports: a case study on Antwerp and Koper portsRebeka Kovačič Lukman, Kristijan Brglez, Damjan Krajnc, 2022, original scientific article Abstract: This paper introduces a conceptual model for evaluating seaports’ acceleration towards the circular economy. The model is based on the identification and definition of circular economy indicators, weighted according to the 9 R-strategy transitions towards the circular economy. We have employed the analytical hierarchy process for weight detection and further calculations of the final seaport circularity value. Our results suggest conceptual validity and provide a detailed insight into the circular activities of the seaports from the indicators, as well as 9 Rs and sustainability perspectives.

10. A conceptual model for a circular city : a case study of Maribor, SloveniaKristijan Brglez, Matjaž Perc, Rebeka Kovačič Lukman, 2024, original scientific article Abstract: Cities play a crucial role in achieving sustainable development. Decision-makers require assistance in developing city transformation plans amidst the emergence of various city models. A content analysis using concept mapping was conducted to examine smart, circular, and green city models. The analysis, supported by Leximancer, revealed that city models are evolving by adopting benefcial solutions from competitors, refecting a strong focus on sustainable development. Additionally, twentyfour research areas essential for implementing a circular city were identifed and validated. Furthermore, a conceptual model for a circular city was developed, incorporating the Defne-Measure-Analyse-Improve-Control tool and a problem-solving system. Testing the model on Maribor highlighted challenges in monitoring the transition towards circularity. The study validates the established model but emphasises the need for further research and case studies to verify its practicality. This scientifc research enhances the understanding of city models and their evolution towards sustainability, providing valuable insights for decision-makers and urban planners.
