Opis: The widespread use of plastics has resulted in significant environmental challenges, including pollution, landfill accumulation, and harm to ecosystems and human health. As concerns over plastic waste intensify, biodegradable plastics have emerged as promising alternatives that can decompose under specific conditions and contribute to a circular economy. This review examines how biodegradable plastics can help address these issues, beginning with the distinction between biodegradable polymers, which are long-chain molecules, and biodegradable plastics, which are end-use materials created by blending these polymers with additives and fillers. It explores common biodegradable polymers, their origins, production processes, and key physical and chemical properties. Further, the review covers both the compounding stage, in which polymers and additives are combined, and the subsequent product development and processing steps involved in manufacturing of biodegradable plastics. A criterion is proposed to assess and rank biodegradable plastics based on their biodegradability. The review also discusses applications and the sustainability of their value chains. Key challenges to widespread adoption, such as technological limitations, economic concerns, and environmental or health risks, are highlighted. Finally, the review stresses the importance of advancing biomass cultivation, polymer development, processing techniques, and degradation methods to unlock the full potential of biodegradable plastics. Overall, it emphasizes the need for continued innovation to promote sustainable materials and improve plastic waste management.

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

Opis: The 8th International Conference on Technologies & Business Models for Circular Economy (TBMCE) was organized by the Faculty of Chemistry and Chemical Engineering, University of Maribor in collaboration with the Strategic Research and Innovation Partnership - Networks for the Transition into Circular Economy (SRIP- Circular Economy), managed by the Chamber of Commerce and Industry of Štajerska. The conference was held in Portorož, Slovenia, at the Grand Hotel Bernardin from September 3rd to September 5th, 2025. EIT RawMaterials RIS Hub Adria, SPIRIT Slovenia Business Development Agency and Pomurje Technology Park (as part of the GREENE 4.0 and CI-Hub projects) have joined us as co-organizers. TBMCE 2025 was devoted to presentations of circular economy concepts, technologies and methodologies that contribute to the shift of business entities and society as a whole to a more responsible, circular management of resources. The conference program included panel discussions, plenary and keynote sessions, oral and poster presentations on the following topics: Sustainable Energy, Biomass and Alternative Raw Materials, Circular Business Models, Secondary Raw Materials and Functional Materials, ICT in Circular Economy, Processes and Technologies. Panel discussions addressed following topics: Circular Economy Transition in South East Europe, The transition to carbon neutrality in energy intensive industry, Valorization of used and contaminated wood, Circular economy trends in construction, Critical raw materials and circular economy transition, Industrial Symbiosis and its opportunities for industry, AI and circular economy. The event was under the patronage of Ministry of the Economy, Tourism and Sport and Ministry of Cohesion and Regional Development.

Opis: Some platforms in the collaborative economy offer a combination of sectoral and information society services, which characterises them as a hybrid entity. The concurrent provision of disparate types of services necessitates the determination of the predominant activity of a given platform on a case-by-case basis. This, in turn, gives rise to legal uncertainty and inconsistent case law at the national level. This paper examines the impact of the choice of institutional alternatives in the context of multilevel governance in the EU on the legal status of collaborative economy business models such as Uber and Airbnb in the EU single market. The paper employs a mixed-methods research approach to analyse pivotal jurisprudential decisions of the Court of Justice of the European Union (CJEU) and national courts. It reaches the conclusion that the Airbnb platform, in its capacity as an information society service provider, is subject to the provisions of the Electronic Commerce Directive (2000/31/EC). Conversely, Uber, by virtue of its definition as a transport undertaking, is subject to shared jurisdiction between EU institutions and Member States in the field of transport services. This paper initiates a discussion on the suitability of the extant regulatory apparatus and underscores the necessity for the establishment of an appropriate institutional framework, either centralised at the EU level or decentralised at the level of Member States, that would provide substantive rules aimed at comprehensively regulating the legal status of hybrid business models, thus allowing for more uniform conditions for their operation in the EU single market.

Opis: This paper aims to examine how the gig economy, as a global trend that is transforming labour markets worldwide, manifests itself in a smaller economy such as Slovenia. Specifically, the paper focuses on how this trend is manifested among Slovenian freelancers, with an emphasis on generational differences. Descriptive statistics, the Mann-Whitney U test and the Chi-square test, were used in the study to explore perceptions and generational differences and to determine whether they are statistically significant. The results show that both younger and older individuals are likely to choose freelance work due to the need for flexibility and independence in project selection, reflecting their desire for greater control over their personal and professional lives. In addition, the research reveals a perception of insufficient support for such new types of careers and a need for educational programmes to improve skills and awareness of the digital labour market. The findings suggest the need for targeted policy measures to support freelancers of different age groups by implementing comprehensive government programs that promote lifelong learning and upskilling, enable the development of local coworking spaces, provide digital market information and include entrepreneurship education and digital literacy in school curricula to strengthen freelance careers, making them sustainable and contributing economically to regional development.
