This study aims to investigate the extent to which the contributions of blockchain technology to supply chain parameters influence blockchain adoption among SMEs. Drawing on contingency theory, the study investigates the moderating effect of market turbulence. The data were collected from 204 SMEs in Malaysia’s manufacturing sector and analysed using the partial least squares technique. The results showed that the intention of SMEs’ managers to adopt blockchain is influenced by the contributions of blockchain to supply chain transparency and agility. Supply chain transparency, alignment, adaptability, and agility are interrelated. Market turbulence moderates positively the association between agility and intention to adopt blockchain. This study extends the literature by decomposing the concept of relative advantages and investigating the influences of blockchain benefits on blockchain adoption. The moderating effect of market turbulence indicates that the influence of blockchain on agility is more important for SMEs operating in a turbulent environment than the SMEs in a stable market. The findings help the policymakers and blockchain vendors in developing effective plans and strategies to speed up the adoption of blockchain among SMEs. Furthermore, the results give confidence to the managers and owners of SMEs that blockchain can be a valuable competitive advantage source.

Despite the hype about blockchains among supply chain management (SCM) practitioners and researchers, the technology’s adoption is still low, and confusion remains about its potential benefits for operational efficiency and effectiveness. Building on a multiple case study research, this paper clarifies current value creation opportunities enabled by the blockchain for product/material tracking and tracing. We highlight that the setup of blockchain projects depends on the presence of different drivers on customer value or efficiency and the focus towards products/components or raw materials. Based on how tracking and tracing drivers and focus influence the initial blockchain setup, contingent factors are discussed and possible evolutionary patterns are identified. These findings are elaborated in one setup matrix and three propositions. The study is one of the few to add empirical evidence to the mainly conceptual SCM blockchain literature and provides a middle-range theoretical contribution based on contingency theory. Furthermore, it offers actionable guidance for managers and policy makers about SCM blockchain adoption.

The objective of this article is to assist the reader in understanding the journey from traditional Supply Chain Management to Digital Supply Chain Management. It aims to augment the concept of Digital Supply Chain Management with blockchain technology and create an extensive literature review to assist in formulating the gaps and discovering the variables that contribute towards the efficiency of a Blockchain-Based Digital Supply Chain. Moreover, this article aims to validate the impact of specified parameters resulting in customer retention and market leadership for an organization. Digital technologies such as the Internet of Things, blockchain, etc., are disrupting the traditional ways of doing business and creating value propositions for customers. Supply Chain Management is a key business process for an organization that helps them compete in the market. Organizations have seized competition not as individual brands but as supply chains. Digital Supply Chain Management is the implementation of digital technologies to capture customer data at every interaction to create customer engagement strategies. This article provides an empirical analysis of parameters influencing a Blockchain-Augmented Digital Supply Chain resulting in customer retention and market leadership and shows how, through a Blockchain-Based Digital Supply Chain, the business objective of being a customer-centric organization is assisted with the customer data generated at each interaction that is enabled.

Abstract The unethical behavior of greenwashing threatens the growth of sustainable products and markets. Greenwashing degrades essential efforts to reduce climate change and pollution and to promote social justice. False marketing communication that claims products are sustainable hurts the value of green products and weakens customer capability to prefer sustainable to nonsustainable products. Greenwashing also eliminates trust in “green” products. Markets infected by fake “green” products ultimately fail to provide the necessary sustainable transformation. Our study demonstrates that consumer access to reliable transparent, traceable, and tamperproof product information counteracts perceived greenwashing among consumers of ecological foods. Furthermore, our data indicate that blockchain information significantly more than certification systems safeguard consumers against the threat of greenwashing. Information validating authenticity promotes the development of sustainable products, protects intellectual property rights for suppliers of green products, and safeguards the supply of green products to consumers. Consumers need key information that ensures the provenance of green products. Conventional wisdom endorses certifications to constrain greenwashing. However, we find that blockchain information dimensions protect brands against perceived greenwashing more robustly than certification systems.

The role of new technologies such as additive manufacturing and blockchain technology in designing and implementing circular economy ecosystems is not a trivial issue. This study aimed to understand if blockchain technology can be an enabler tool for developing additive symbiotic networks. A real case study was developed regarding a circular economy ecosystem in which a fused granular fabrication 3D printer is used to valorize polycarbonate waste. The industrial symbiosis network comprised four stakeholders: a manufacturing company that produces polycarbonate waste, a municipality service responsible for the city waste management, a start-up holding the 3D printer, and a non-profit store. It was identified a set of six requirements to adopt the blockchain technology in an additive symbiotic network, bearing in mind the need to have a database to keep track of the properties of the input material for the 3D printer during the exchanges, in addition to the inexistence of mechanisms of trust or cooperation between well-established industries and the additive manufacturing industry. The findings suggested a permissioned blockchain to support the implementation of the additive symbiotic network, namely, to enable the physical transactions (quantity and quality of waste material PC sheets) and monitoring and reporting (additive manufacturing technology knowledge and final product's quantity and price). Future research venues include developing blockchain-based systems that enhance the development of additive symbiotic networks.

Oil and gas (O&G) supply chain management (SCM) is complex because it deals with different geographic locations to manage demand and supply, transportation, inventory, and distribution. Blockchain technology has created an interesting research gap in the SCM domain, and this study is designed to describe the relevancy of blockchain technology for O&G SCM. SCM is based on agile and lean supply chains (SCs). Agile SC focuses on increasing flexibility and responsiveness to gain competitive advantages, and lean SC is based on eliminating waste and processes to improve firm performance. This study is an initial effort to propose a framework that suggests the implication of blockchain for O&G by providing an overview of O&G SCM. Data were collected from SC managers of O&G companies, and we analyzed the impact of agile and lean SCs on firm performance. The results indicate that agile SC is highly important for O&G industries in comparison to lean SC. This study proposes the key requirements of agile SC and how blockchain can uplift agile SC technology with state-of-the-art properties such as data-driven management, information sharing, data privacy, cyber-security, transparency, smart contracts, visibility, traceability, and reliability, which boost SC agility as well as firm performance.

The circular economy (CE) has emerged as a paradigm to protect the environment and the well-being of future generations. In parallel, Blockchain technology (BC) has emerged as a critical enabler for accelerating the transition toward a CE. In order to understand and summarize prior research on the role of BC in the CE, we conducted a systematic literature review (SLR) of 70 seminal articles published before July 2022. Six main themes emerged: a) CE approaches and practices, b) BC and the integration of the Internet of Things (IoT), c) sustainable supply chain management, d) BC and the CE in the COVID-19 era, e) sector-specific BC applications, and f) barriers to BC adoption in the CE. Furthermore, we develop a comprehensive framework that integrates stakeholders, strategies and practices, industrial sectors and a BC-enabled CE.

The adoption of blockchain technology (BCT) in a supply chain holds great potential for textile industries by executing transactions among stakeholders in a most reliable and verifiable way. Textile industries in emerging economies, like Pakistan, confront severe economic pressures and uncertain environment and strive to achieve sustainable supply chain excellence through blockchain implementation. This study is an initiative to analyze the key barriers in adopting BCT-related practices within the textile industry. This study conducts an extensive review of the literature using fuzzy Delphi approach for finalizing the barriers and applied fuzzy analytical hierarchy process (AHP) for prioritizing the barriers under uncertain environment. Based on the extensive review of the literature and panel discussions with experts, a total of five main barriers and 21 sub-barriers were categorized and ranked. The results and findings prioritize technological and system-related barriers (TSB) first, and human resources and R&D (HRB) barriers second among the other barrier dimensions. This paper highlights the need for an inclusive understanding of the various technological, environmental, and socio-economic perspectives to create blockchain applications that work for the textile sector. This study’s key findings and policy guidelines can assist concerned stakeholders in making strategic decisions for adopting BCT within the textile supply chain. The managerial implications are provided for the industrial decision-makers and policymakers aiming to integrate BCT into the supply chain processes. Presently, there exists no research in the context of Pakistan that highlights the challenges faced during the adoption of BCT in the supply chain. For this purpose, an approach in the form of an integrated model based on fuzzy set theory is developed. Finally, the robustness of the proposed model is checked through sensitivity analysis.

Purpose The aim of the research is to identify and prioritise the implementation challenges of blockchain technology and suggests ways for its implementation in supply chains. Design/methodology/approach Underlined by the technology, organisational, and external environment model, a conceptual framework with four challenge categories and sixteen challenges is proposed. Data collected from three stakeholder groups with experience in the implementation of blockchain technology in India is analysed by employing an analytical hierarchy process method-based case study. Further, a criticality–effort matrix analysis is performed to group challenges and suggest ways for implementation. Findings The analysis revels that all stakeholders perceive complexity challenge associated with the technology, organisational structure, and external environment, and issues of compatibility with existing systems, software, and business practices to be high on the criticality and effort scales, which thus require meticulous planning to manage. Likewise, top-management support issues related to insufficient understanding of how technology fits with the organisation’s policy and benefits offered by the technology requires high effort to address this challenge. Research limitations/implications The results were obtained by focusing on the Indian context and therefore may not apply to other nations’ contexts. Practical implications By investigating the challenges that the developers, consultants, and client organisations need to address, this study assists managers in developing plans to facilitate coordination among these organisations for successful blockchain implementation. Originality/value To the authors’ knowledge this study is the first to identify and prioritise the challenges from the perspectives of multiple stakeholder groups with experience in blockchain technology implementation.

This article interrogates the turn towards digital technologies for addressing sustainability challenges in global supply chains. Focusing on the case of blockchains, we assess industry claims that this set of distributed ledger technologies for undertaking, verifying, and publishing digital transactions provides the greater transparency necessary to resolve sustainability challenges. Our central contention is that blockchain-based initiatives to promote sustainability in global supply chains double-down on modes of third-party audit and disclosure governance that have thus far failed to address labour and environmental abuses. The turn towards these digital technologies, we show, extends interlinked processes of managerialization and the spread of ‘audit culture’ in the governance of global supply chains. These tendencies heighten obstacles to enhancing sustainability across global supply chains, exacerbating the very challenges blockchain initiatives are ostensibly meant to address. Worse than not fundamentally addressing sustainability problems, applications of this set of ‘sustech’ render failures to address sustainability abuses more opaque. The technological novelty of blockchain helps to construct what we call a ‘veil of transparency’ over sustainability abuses and marginalities in and across global supply chains.

Blockchain is attracting tremendous attention in the logistics industry on account of its cutting-edge appeal, potential for integration within the sector, and capacity to disrupt established practices. Among other things, blockchain technology promises to open up new horizons in traceability, transparency, accuracy, and safety throughout the supply chain. However, as an emerging technology, blockchain is still relatively nascent, and familiarity with the technology is limited, as are its implementations. In addition, there is a dearth of studies concerning blockchain technology specifically, as it pertains to transport and logistics, as opposed to finance and cryptocurrency. It remains unknown what factors enable blockchain adoption by logistics service providers and how its adoption affects firm performance and capabilities. This research examines extant literature and conducts research on an eminent global transportation company to elucidate the potential influence of blockchain adoption on firm performance. The results of this work support the model that advancing theory-driven and empirical blockchain studies will increase firm capabilities and foster a competitive edge in the emerging digitalized era.

Climate change poses a real risk, as does a shortage of resources to accommodate the world's rising population. Every nation is trying to produce maximum without caring for the environment. As a result, the circular economy (CE) is critical to the long-term sustainability of society, business and the environment. Government and policymakers are forcing industries and organizations to adopt or establish CE in their businesses to protect the environment. However, the concept of CE is unclear, and there are various hurdles and barriers to adopting a CE in industries and organizations. For a sustainable environment, CE barrier management plays a crucial role. This paper aims to explore and prioritize barriers to establishing a CE. A detailed methodological literature review is carried out to explore the twenty-nine barriers in CE. The various barriers to CE are prioritized using the Multi-criteria decision-making methods Order of Preference by Similarity to Ideal Solution (TOPSIS). Based on the TOPSIS barrier of increased emission and pollution while recycling was found to be a top rank and the barrier of tedious environmental regulations and lack of government support was found to be at the lowest rank. The top priorities are the barriers to increasing emission and pollution while recycling, radically changing production, and lack of public participation in using recycled products. The Blockchain-IoT architecture and strategies are developed to mitigate all these barriers. As in CE, resources are not ending as these are recyclables since products are made to last several life cycles. Product's lifespans are extended by maintaining, repairing and re-manufacture to reduce carbon footprints in the environment. This barrier ranking will help supply chain professionals and business executives analyze the failure to implement CE in industries. Strategies and architecture based on blockchain-IoT will also help in mitigating the barrier in CE. This study will give new dimensions for the adaption of CE in industries. CE will create sustainable ecosystems for soil, air and water. These sustainable ecosystems provide a long and healthy life for all living things on this planet.

The chances of food contamination and spoilage get enhanced as it passes through various stages, and prudent consumers often need transparency on the origin of food products, their production and processing facilities utilized. Blockchain, an emerging digital technology, offers food traceability solutions to consumers and supply chain partners. But presently, blockchain adoption in Indian supply chains is in the nascent stages. The present study identified the challenges of adopting blockchain technology in Indian food supply chains and modelled them using Interpretive Structural Modelling (ISM). As per the ISM, the ‘regulatory structure’ and ‘lack of realised need’ emerged as the most significant driving forces that impact other challenges, viz. ‘privacy breach issues’, ‘high costs’, ‘lack of skills’, ‘lack of technology’, ‘lack of trust’ and ‘lack of infrastructure’. These challenges have an impact on the ‘scalability problem’. The paper underlines the significance of enabling regulatory structure, improved information and communication technologies infrastructure, and convincing the supply chain stakeholders to use blockchain technology to resolve the underlying challenges and achieve its adoption and scalability in the Indian food industry.

The increasing demand for a sustainable, reliable and secure supply chain for food products has led to the application of digital technologies such as blockchain to improve operational effectiveness. The purpose of this paper is to investigate the integration barriers of Blockchain Technology (BCT) within Circular Food Supply Chains (CFSCs) towards firm’s operational effectiveness through a multi-methodological process. Initially the integration barriers are identified through a review of literature and these risks are categorised, using evidence obtained by survey questionnaire completed by experts in the integrated research arena. A further quantified prioritisation of these barriers is made by utilizing a Fuzzy Delphi approach, validated by expert practitioners drawn from the food production and supply organizations. Finally, through semi-structured interviews with Blockchain and Food Supply Chain (FSC) experts, an examination of how the integration barriers affect operational effectiveness may be mitigated is provided. This paper concludes that the identified barriers to blockchain integration have an incremental and real impact on the operational effectiveness of the firm that can only be further clarified through industry-wide standardised processes. Finally, the experts consider blockchain technology an infrastructural addition and enabler of operational effectiveness and not an all-problem solution.

A transition towards a circular economy within the agri-food sector requires the improvement of efficiency in resource utilization, the prevention of food loss or waste, whilst adopting regenerative agricultural practices. In addition to the technical challenges, the agri-food industry needs to address the food safety concerns resulting from biomass recycling processes. Increasingly, blockchain technology is gaining traction, moving towards more sustainable and precision agriculture. The blockchain is a decentralized, immutable, and shared database that records the provenance of digital assets, making it a suitable platform for traceability and food supply chain management. Despite its growing importance, the existing literature regarding these themes and the empirical evidence of blockchain-based solutions for a circular economy is rather fragmented. This paper offers a scoping review regarding the role of blockchain technology in the transition towards a circular food system. A total of 44 papers published in peer-reviewed journals were reviewed to identify new scientific insights into the application of blockchains within the agricultural sector. The results indicate that blockchain technology has a great potential in reducing food loss through optimized eco-efficiency (e.g., digitalization and integration with the Internet of Things) and by alleviating asymmetric information (by increasing transparency and reducing dependence on intermediaries). However, in the case of recycling efficiency, despite its potential, there remains a paucity of evidence regarding the use of blockchain technology in improving the residual valorization processes. Furthermore, there is a stream of literature focusing on the ability of blockchain-enabled traceability (e.g., for organic production or supply chain management). Yet, the role of blockchain traceability in the monitoring of risks from recycled biomass and the reporting of the sustainability performance in the supply chain has received scant attention within research literature. These results provide insights for supply chain management operations with the view of shifting towards a circular economy whilst also suggesting an agenda for future research areas.
