The transition to a circular economy (CE) in plastic packaging faces persistent barriers, including regulatory fragmentation, technological limitations, and supply chain disconnection. This study examines how multinational companies address these challenges by leveraging enablers such as advanced policies, technological innovation, and cross-sectoral collaboration. Based on a PRISMA-guided systematic review and a descriptive–explanatory case study, semi-structured interviews with senior managers were analyzed through thematic coding and data triangulation. Findings reveal that regulatory measures like virgin plastic taxation and post-consumer recycled material (PCR) incentives are effective only when synchronized with technical capacities. Investments in recycling infrastructure and circular design, such as resin standardization, enhance the quality of secondary materials, while local supply contracts and digital traceability platforms reduce volatility. Nevertheless, negative consumer perceptions and inconsistent PCR quality remain major obstacles. Unlike prior studies that examine barriers and enablers separately, this research develops an integrative framework where their interaction is conceptualized as a systemic and non-linear process. The study contributes to CE theory by reframing barriers as potential drivers of innovation and provides practical strategies, combining policy instruments, Industry 4.0 technologies, and collaborative governance to guide multinational firms in accelerating circular transitions across diverse regulatory contexts.

The linear construction model is characterized by resource-intensive processes that generate significant waste, whereas adopting circular economy principles facilitates sustainable, adaptable, and recyclable building practices to mitigate waste and conserve resources. The primary objective of this study is to empirically analyze the impact of barriers and drivers on sustainable construction practices and to evaluate the role of organizational culture in moderating this relationship. This study, grounded in Circular Economy theory, distributed 210 questionnaires using simple random sampling to large contractors (501–3000 employees) in Saudi Arabia’s Eastern Region, yielding 154 acceptable responses and a 73% completion rate. Data analysis was conducted using SmartPLS software, revealing that barriers, drivers and organizational culture positively impact sustainable construction practices, with organizational culture also positively moderating the connection among drivers and sustainable construction practices. However, organizational culture was not observed to substantially influence the connection between barriers and sustainable practices. The results highlight the main contribution of organizational culture in supporting sustainable development, offering significant theoretical contributions and practical implications for industry leaders and policymakers to develop regulatory framework and implement strategies that support sustainability.

Cities are significant contributors to climate change, environmental degradation, and resource depletion. To address these challenges, sustainable strategies in building design, construction, and management are essential, and digitalisation through the integration of Building Information Modelling (BIM) and Life Cycle Assessment (LCA) can enable it. However, the environmental benefits of BIM–LCA integration remain underexplored, limiting broader practical adoption. This study systematically reviews 80 case studies (2015–2025) to assess how recent applications address known barriers and to identify enablers of successful BIM–LCA workflows. The analysis highlights a growing alignment between technological, regulatory, and methodological advancements and practical implementation needs, especially as technical barriers are increasingly overcome. Nevertheless, systemic challenges related to institutional, behavioural, and socio-economic factors persist. From a stakeholder perspective, four thematic drivers were identified: material circularity and resource efficiency; integration with complementary assessment tools; energy-performance strategies for comfort and efficiency; and alignment with international certification systems. The study offers a stakeholder-oriented framework that demonstrates the multi-level value of BIM–LCA integration not only for environmental impact assessment but to support informed decision-making and reduce resource consumption. These insights aim to bridge the gap between academic research and practical implementation, contributing to the advancement of sustainable practices in the built environment. Full article

Industry 4.0 (I4.0) is reshaping manufacturing by integrating advanced digital technologies and is increasingly seen as an enabler of the circular economy (CE). However, most research treats digitalisation and circularity separately, with limited empirical insight regarding their combined implementation. This study investigates I4.0 adoption to support sustainability and CE across industries, focusing on how enterprise size influences adoption patterns. Based on survey data from 69 enterprises, the research examines which technologies are applied, at what stages of the product life cycle, and what barriers and drivers influence uptake. Findings reveal a modest but growing adoption led by the Internet of Things (IoT), big data, and integrated systems. While larger firms implement more advanced tools (e.g., robotics and simulation), smaller enterprises favour accessible solutions (e.g., IoT and cloud computing). A positive link is observed between digital adoption and CE practices, though barriers remain significant. Five main categories of perceived obstacles are identified: political/institutional, financial, social/market-related, technological/infrastructural, and legal/regulatory. Attitudinal resistance, particularly in micro and small enterprises, emerges as an additional challenge. Based on these insights, and to support the twin transition, the paper proposes targeted policies, including expanded funding, streamlined procedures, enhanced training, and tools for circular performance monitoring.

Valuable eco-innovations are emerging through increasingly close collaboration between the scientific community, industry, the energy sector, and public institutions supporting research, development, and the commercialization of new technologies that address specific market needs. Today, the implementation of eco-innovations is a key factor across many sectors and constitutes a significant barrier to market entry. This study identifies the key drivers of the implementation of eco-innovation in the Polish tire industry, which ranks among the lowest in the EU in terms of the adoption of eco-innovation. Legal regulations—particularly those related to the circular economy and Extended Producer Responsibility (EPR)—emerged as the strongest drivers, as indicated by over 60% of the companies surveyed. Financial support and incentives, such as tax relief, were emphasized by 70% of respondents as crucial for accelerating eco-innovation. This study also highlights significant barriers, including limited access to capital (cited by 65% of respondents) and the high costs associated with eco-innovative methods. Green public procurement and the certification status were recognized as important, albeit less impactful, factors. Expert interviews confirm these findings, underscoring the need for improved public funding mechanisms and stronger legislative support to overcome the current stagnation. This research concludes that without such measures, progress in eco-innovation within the sector may remain slow, thereby hindering the achievement of sustainable development goals. Full article

The Mediterranean region is increasingly confronted with intersecting environmental, agricultural, and socio-economic challenges, including biowaste accumulation, soil degradation, and high dependency on imported fossil fuels. Biomethane, a renewable substitute for natural gas, offers a strategic solution that aligns with the region’s need for sustainable energy transition and circular resource management. This review examines the current state of biomethane production in the Mediterranean area, with a focus on anaerobic digestion (AD) technologies, feedstock availability, policy drivers, and integration into the circular bioeconomy (CBE) framework. Emphasis is placed on the valorisation of regionally abundant feedstocks such as olive pomace, citrus peel, grape marc, cactus pear (Opuntia ficus-indica) residues, livestock manure, and the Organic Fraction of Municipal Solid Waste (OFMSW). The multifunctionality of AD—producing renewable energy and nutrient-rich digestate—is highlighted for its dual role in reducing greenhouse gas (GHG) emissions and restoring soil health, especially in areas threatened by desertification such as Sicily (Italy), Spain, Malta, and Greece. The review also explores emerging innovations in biogas upgrading, nutrient recovery, and digital monitoring, along with the role of Renewable Energy Directive III (RED III) and national biomethane strategies in scaling up deployment. Case studies and decentralised implementation models underscore the socio-technical feasibility of biomethane systems across rural and insular territories. Despite significant potential, barriers such as feedstock variability, infrastructural gaps, and policy fragmentation remain. The paper concludes with a roadmap for research and policy to advance biomethane as a pillar of Mediterranean climate resilience, energy autonomy and sustainable agriculture within a circular bioeconomy paradigm.

Circular economy marketing (CEM) represents an innovative approach to aligning business strategies with sustainability objectives. This paper explores the role of CEM as a driver of green marketing innovation, emphasising strategies that minimise environmental impact on business competitiveness while enhancing consumer engagement. Using a systematic literature review based on the PRISMA methodology, we identified 39 high-impact studies across multiple industries, categorising findings into key themes, theoretical frameworks, and marketing strategies. The analysis highlights emerging trends, including the shift toward product-service systems (PSSs), behavioural nudging, transparent sustainability branding, and integration of digital technologies such as AI and blockchain to enhance traceability and consumer trust. Findings reveal that while circular economy marketing presents opportunities for businesses to differentiate themselves and build long-term sustainability strategies, significant challenges remain, including scalability issues, consumer scepticism, and risks of greenwashing. Moreover, gaps in standardising impact measurement and industry-specific adaptation hinder wider implementation. Business model innovation, policy support, and collaborative efforts are crucial in overcoming these barriers. This study provides insights for businesses, policymakers, and researchers, highlighting how CEM fosters green innovation and competitiveness. Future research should compare the effectiveness of various strategies to accelerate the transition toward sustainable marketing practices through regulation and interdisciplinary collaboration.

Ensuring sustainable consumption of water, which is essential for human development, is not sufficient, therefore, there is an urgent need to improve reuse of treated wastewater. This paper reviews the newest EU legislation related to reclaimed water reuse, which is the main driver for change. While there are some positive developments in the EU, the paper argues that the current EU legislation does not sufficiently encourage circular solutions, especially on how to deal with any bottleneck effects, which prevent to fully utilise wastewater. This reflection is noted based on the national and regional developments in Italy with some comparison with other Southern countries, such as Greece and Spain in attempt to identify good practices as well as any barriers for the reclaimed water to be reused.

This work discusses the drivers and barriers (legal, chemical, biological, technical) related to implementing a circular economy model in the tire sector in Poland. The aim of this work was to identify and prioritize key factors determining the implementation of the circular economy business model, both among tire manufacturers and recyclers. The analysis of aspects facilitating the implementation of circular economy and the assessment of this type of project in organizations was the basis for identifying the most important factors in the development of eco-innovation in the tire industry. The research process used bibliometric analysis, empirical research based on a questionnaire and in-depth interviews of tire industry employees, and opinions of experts participating in a group interview. Research has indicated that the key to success in implementing the circular economy is to change actual business practices. The basic drivers of circular economy implementation in the tire sector are legal requirements and an organization’s profit associated with the use of circular economy actions. High environmental requirements and regulations that support a circular economy are key factors stimulating eco-innovative methods, but in most cases, these are more of a concern for recyclers than tire manufacturers. This study identified and hierarchized the determinants for implementing a circular economy model and indicated key factors influencing the development of eco-innovations among recyclers and tire manufacturers in Poland.

The automotive supply chain is one of the top eight value chains that cause 50% of global emissions. Despite its significance, limited literature has researched the role of insurance companies in addressing automotive supply chain emissions. This research explores strategies developed by insurance companies for addressing carbon emissions in the automotive supply chain in the UK. It employs a qualitative multiple case study approach and conducts in-depth analysis of main drivers, barriers, and strategies in four insurance companies in addressing automotive supply chain emissions. It finds that cost savings and competitive advantage, changing mindset, impending regulation, market changes, and increased connectedness are the main drivers. But further progress is slowed down by five main barriers: ‘the complexity of tracking and quantifying emissions’, ‘conflicts of interest in the supply chain’, ‘skill shortage’, ‘lack of accountability’, and ‘profit prioritisation’. To overcome this, the study establishes five main strategies for insurance companies to follow: ‘circular business model with green parts and repair-over-replace methodologies’, ‘supply chain collaboration’, ‘quantifying emissions and setting key performance indicators’, ‘higher weighting for ESG in tenders and policies’, and ‘education and awareness’. If followed correctly, businesses will be able to achieve ‘emission reductions’, ‘gain competitive advantage’, and ‘reduce costs in the supply chain’. Taking into account these findings and the academic literature, this study develops a framework for insurance companies to mitigate automotive supply chain emissions. This is one of the first papers to study carbon emissions in automotive supply chains from the perspective of the insurance industry. It provides practical implications for the insurance industry in developing carbon emission strategies in automotive supply chains. Full article

As the construction sector is one of the most carbon-intensive and resource-intensive industries, the necessity for a transition from a linear to a circular economy is widely acknowledged. Aimed at facilitating the transition, several policy frameworks, operational tools and assessment instruments have been developed in recent decades. Nevertheless, the integration of circularity in the construction sector remains constrained and haphazard, frequently focusing solely on the production phase and neglecting the comprehensive impacts within the overall process. The detected gap between theoretical framework and practical implementation is reflected by the limited coordination between policies and tools, which creates a significant obstacle to the adoption of consistent and effective practices. A dual analysis is conducted, comprising two parallel domains: an investigation of a circular policy theoretical framework in urban environments through a literature review, and an analysis of practice-oriented tools through resilience assessment and green building rating systems. As a result, common ground and shared targets are identified between the two scopes, as well as contrasts and inconsistencies that require further attention. These are classified according to their role as barriers or drivers of change, and recommendations for synergistic improvement between policies and tools are provided. Full article

This study explores the drivers and barriers of the Circular Economy (CE) in Tunis Village, a rural tourism destination, as a case study of emerging economics. We adopted an exploratory case study methodology. Telephone interviews (n = 10) with stakeholders were conducted, and a survey of employees (n = 123) was distributed. Qualitative data were thematically analyzed, and quantitative data were descriptively presented. The results show that improving relationships with the local community, gaining financial benefits, and improving relationships with suppliers were the top perceived drivers. The top perceived barriers are poor economic development, which makes the implementation of large-scale sustainability difficult; a lack of technology and advanced technologies; and the absence of effective and integrated waste management and recycling systems. Considering the exploratory nature and design of this study, the results cannot be generalized. However, the results can help plan future research on a larger scale in developing economies. Furthermore, the findings can inform policymakers on how to better apply CE practices in rural tourism destinations. The topic of CE has been under-researched in connection with developed countries, and this study is the first to examine CE in rural tourism destinations in emerging countries. This underlines the specific drivers and barriers related to CE as a sustainable development practice. Additionally, it contributes to the academic debate on this notion. Full article

Replacing fossil-based feedstock with renewable alternatives is a crucial step towards a circular economy. The bio-based plastics currently on the market are predominantly used in single-use applications, with remarkably limited uptake in durable products. This study explores the current state of the art of bio-based plastic use in durable consumer products and the opportunities and barriers encountered by product developers in adopting these materials. A design analysis of 60 durable products containing bio-based plastics, and 12 company interviews, identified the pursuit of sustainability goals and targets as the primary driver for adopting bio-based plastics, despite uncertainties regarding their reduced environmental impact. The lack of knowledge of bio-based plastics and their properties contributes to the slow adoption of these materials. Furthermore, the lack of recycling infrastructure, the limited availability of the plastics, and higher costs compared to fossil-based alternatives, are significant barriers to adoption. Product developers face significant challenges in designing with bio-based plastics, but opportunities exist; for example, for the use of dedicated bio-based plastics with unique properties. When designing with bio-based plastics, product developers must think beyond the physical product and consider sourcing and recovery, which are not typically part of the conventional product design process.

The Circular Bioeconomy (CBE) combines the concepts of bioeconomy and a circular economy. As an alternative concept to the current fossil-based, linear economy, it describes an economy based on the efficient valorization of biomass. It is regional in nature and aims to improve sustainability. An analysis of the transition process, by identifying its success criteria and assessing its impacts through the modeling of technology-specific scenarios, is necessary to ensure that CBE concepts are sustainable. However, a comprehensive consideration of regional influences on both is lacking. Based on extensive literature research and an expert survey, we develop a multi-criteria approach where we (i) present a comprehensive catalog of CBE success criteria and discuss their region-specific characters and (ii) develop a methodology based on evaluation matrices that enable CBE technologies to be matched with regions. The matrices support the evaluation of technological and regional characteristics influencing successful CBE implementation. The results show that the success criteria “biomass resources”, “technological”, and “social” are perceived as highly important, and that most of the success criteria are both region- and technology-specific, highlighting the relevance of developing matrices to match them. We describe such matrices indicatively for the two broadest and most important success criteria clusters “social acceptance” and “biomass supply chain”. With this, we substantiate the regional nature of CBE and raise the awareness on the importance of considering regional conditions in CBE transition processes. Furthermore, we provide practical guidance on how regional conditions can be reflected in the selection of technologies, e.g., in regional CBE technology scenarios. Full article

Contemporary societies, whether they have reached advanced levels of economic and social development or are still developing, need to prioritise the implementation of circular economy practices. This will facilitate the shift towards regenerative, sustainable, and closed-loop industrial systems. For now, there are some efforts to encourage patterns of production and consumption through changes in economic trends, development of institutional frameworks, harmonising regulations in the field of environmental protection, and raising the level of social awareness to achieve, above all, greater efficiency of resources. Extensive literature that deals with monitoring the implementation of the circular economy already indicates the existence of numerous barriers in this process but also notices some incentives for raising the degree of circularity of the observed systems. In this paper, the question of whether a single value can represent the level of circularity of the chosen material/product chain is researched. An overview of barriers and drivers for implementing circular economy strategies is given to structure a proper metric framework in correlation to the research question. The objective was to simplify the monitoring of circularity by developing a unique index for comparing material/product chains in similar systems. This was accomplished by using the circular material use (CMU) rate introduced in the European Union and modifying it for financial data calculation. As a result, the circular economy index, which covers all 9R strategies (CEI_R), is obtained. The practical verification of model applicability was shown by determining the degree of circularity achieved for passenger cars in the four observed EU countries. Full article
