Publication Name: Circular Economy and Sustainability

Publication Date: 2023-03-01

Volume: 3

Issue: 1

Page Range: 125-166

Description:

The circular economy (CE) field has recently attracted significant interest from academics and practitioners. CE represents a departure from the linear economy, which is characterised by unsustainable resource production and consumption. The growing number of publications necessitates a comprehensive analysis of this field. This is the first systematic examination of the knowledge base and knowledge diffusion pathways in the CE domain. We analyse a Web of Science dataset containing 5431 articles published between 1970 and 2020. To create a comprehensive review of the CE domain, we conducted a keyword co-occurrence network analysis. We examined four distinct types of main paths using the main path analysis (MPA) technique: forward, backward, global, and key-route. According to the analyses, CE research focuses on six primary research themes: CE and sustainability, bioeconomy, CE practices, lifecycle assessment and industrial symbiosis, construction activities, and waste management. In addition, the MPA demonstrates that the CE literature has recently focused on Industry 4.0 technologies and their contribution to CE. This is the first attempt to depict the genealogy of CE research so that scholars can comprehend the domain’s evolutionary structure, identify hot topics, and capture the history, development status, and potential future directions of CE research.

Barriers to Blockchain Adoption in the Circular Economy: A Fuzzy Delphi and Best-Worst Approach

Suhaiza Zailani John G. Keogh Abderahman Rejeb Karim Rejeb

Publication Name: Sustainability Switzerland

Publication Date: 2022-03-01

Volume: 14

Issue: 6

Page Range: Unknown

Description:

Blockchain can help to fundamentally alter aspects of circular economy (CE) activities and overcome pressing sustainability issues. Nevertheless, limited studies have investigated the barriers to blockchain adoption in the CE. This study aims to close the knowledge gap by providing a comprehensive review of the barriers hampering the adoption and integration of blockchain technology in the CE. An integrated approach based on fuzzy Delphi and best-worst methods has been applied to analyze and rank the barriers. Sixteen barriers to blockchain adoption in the CE were identified from the academic literature and validated by a panel of experts. The findings from the fuzzy Delphi technique identified ten significant barriers for further analysis. Then, using the best-worst method, the optimal weights were determined based on the experts’ judgment to recognize the importance of each barrier. The findings from this method showed that a lack of knowledge and management support, reluctance to change and technological immaturity are the most significant barriers. In contrast, the least significant barriers are investment costs, security risks, and scalability issues. Theoretically, this study is the first to apply an integrated approach combining fuzzy Delphi and best-worst techniques to prioritze the barriers to blockchain adoption in the CE. It also provides valuable insights for managers and decision-makers that can be used to optimize blockchain implementations in the CE.

Description:

To address consumers’ concerns regarding food integrity, halal food businesses need to rethink their conventional supply chains and leverage new technologies. The emergence and proliferation of the Internet of Things (IoT) - the use of interconnected devices, sensors, and technologies to orchestrate, monitor, and optimize supply chain processes - holds innovative potentials for the halal food supply chain (HFSC). Despite the growing popularity in supply chain management and logistics, the potentials and challenges of IoT in the HFSC remain – unexplored and further research is required. Therefore, the goal of this paper is to address this knowledge gap and review IoT research within the context of HFSCs. To begin, over seventy-three (73) papers were analyzed using both bibliometric techniques and in-depth content analysis. The results reveal that IoT offers five major benefits for the HFSC; namely, traceability of products, enhancement of supply chain efficiencies, facilitation of livestock management, authentication of foods’ halal status, and monitoring of halal certifications. Several challenges were identified, including the technical limitations of IoT devices, technological immaturity, lack of user acceptance, and cost and regulatory barriers. The study's findings provide deeper insight into the current state of IoT research in the halal food literature, its development, challenges and future research avenues for scholars, policy makers and the HFSC community.

Volume: 24

Issue: 5

Page Range: 554-595

Description:

Halal food supply chains (HFSCs) are increasingly characterized by fragmentation, complexity, and uncertainty. Halal food consumers are becoming more demanding for food quality and compliance with Islamic dietary law. As sustainability is a multidimensional concept that entails several aspects and interpretations, the objectives of HFSCs significantly overlap with the sustainable dimensions of the food ecosystem. The purpose of this study is to examine the inherent sustainable aspects and characteristics of HFSCs. Therefore, a systematic literature review and a bibliometric analysis were conducted to redress the lack of academic attention being given to the relationships of HFSCs with sustainability. Selected 74 papers were coded and analyzed according to the dimensions of sustainability, namely, the economic, social, and environmental dimensions. The review primarily attempts to provide answers to the following research question: What are the sustainable aspects of HFSCs? We provide a comprehensive analysis of the three critical components of sustainability, offering a broad and comprehensive picture of many critical issues in HFSCs. Finally, the contribution of the study, the scope of future research, and the limitations are highlighted in detail.

Issue: 4

Page Range: Unknown

Description:

Blockchain technology has emerged as a promising technology with far-reaching implications for the food industry. The combination of immutability, enhanced visibility, transparency and data integrity provides numerous benefits that improve trust in extended food supply chains (FSCs). Blockchain can enhance traceability, enable more efficient recall and aids in risk reduction of counterfeits and other forms of illicit trade. Moreover, blockchain can enhance the integrity of credence claims such as sustainably sourced, organic or faith-based claims such as kosher or halal by integrating the authoritative source of the claim (e.g., the certification body or certification owner) into the blockchain to verify the claim integrity and reassure business customers and end consumers. Despite the promises and market hype, a comprehensive overview of the potential benefits and challenges of blockchain in FSCs is still missing. To bridge this knowledge gap, we present the findings from a systematic review and bibliometric analysis of sixty-one (61) journal articles and synthesize existing research. The main benefits of blockchain technology in FCSs are improved food traceability, enhanced collaboration, operational efficiencies and streamlined food trading processes. Potential challenges include technical, organizational and regulatory issues. We discuss the theoretical and practical implications of our research and present several ideas for future research.
