Life after use: circular supply chains for second-life of electric vehicle batteries

Despite the increasing interest in second-life of electric vehicle batteries, the characteristics of supply chains to support such products are yet to be developed. The purpose of this paper is to investigate the key supply chain characteristics required to effectively accommodate circular models for second-life electric vehicle batteries. Through a longitudinal case study, we map possible application areas and customer segments, necessary key activities, and potential actors that might emerge in future supply chains for these products. The findings are discussed in relation to product-oriented, use-oriented, and result-oriented circular models. The suggested circular models and their comparisons provide insights into how different supply chain dimensions are configured for different circular business models, and the advantages, disadvantages, and prerequisites associated by each model.

Spraying for the beauty: Pesticide use for visual appearance in apple production

AbstractPesticides are used to reduce yield losses and to enhance the visual quality of products. However, pesticide use raises concerns due to negative health and environmental effects, hence ambitious policy goals for their reduction have been established. Reducing pesticides which mainly focus on visual quality of products could be an efficient strategy to contribute to these goals, without reducing food production. However, the role of “cosmetic” pesticide use is so far not well documented and understood. Here, we quantify cosmetic pesticide use and the influence of supply chain characteristics on their use. We focus on table apple production, where the visual quality of products is a key aspect. Using a sample of 196 apple growers in Switzerland, we find that 23.5%–59.2% of growers use cosmetic pesticides for the apples’ visual appearance. Farms mainly marketing via intermediaries are 23.9‐29.6% more likely to spray cosmetic pesticides for visual purposes compared to farms mainly direct marketing. Our findings highlight the role of supply chains in farmer decision‐making, recommending a decrease in the focus on visual product quality, especially in retail environments, thus minimizing unnecessary and irreversible risks of pesticide exposure by farmers without compromising food security.

Research on the Application of Green Supply Chain Management: Based on SCOR Model

This paper takes Apple Inc. as the research object and explores the green supply chain management issues based on the SCOR model. By combining the SCOR model through the theoretical framework and the characteristics of Apple's supply chain, management practice suggestions are made to reveal Apple's green performance in terms of environment, resources, and social responsibility. The study results show that Apple performs better in green procurement and marketing, but is slightly inferior in green recycling storage, and transportation. This provides valuable ideas for Apple's subsequent industrial sustainable development strategy, as well as lessons and references for other companies and industries, helping to promote the green development of the entire supply chain industry. In the future, it will be a key area to continue in-depth research on promoting and optimizing green supply chain practices in different industries and enterprises of different sizes.

Research on the Resilience Assessment of Cross-border E-commerce Supply Chains under the RCEP Agreement

Under the RCEP (Regional Comprehensive Economic Partnership) agreement, cross-border e-commerce supply chains face the multiple risks that can lead to supply chain disruptions, severely affecting a nation's economic security, trade stability, and international market competitiveness. Enhancing supply chain resilience is a key method to address supply chain disruptions. This study, based on an analysis of the characteristics of cross-border e-commerce supply chains, utilizes Grounded Theory and Social Network Analysis to construct an evaluation indicator system. The resilience indicator system for cross-border e-commerce supply chains under the RCEP agreement developed in this study aids in the efficient and stable development of businesses.

효율적 및 반응적 공급사슬 구성 제조기업의 제3자 물류기업 선정요인의 우선순위와 가중치 분석

Using AHP, it is to clearly analyze that there is a difference in the importance and weight of the selection criteria factors that should be applied first in the selection of a third-party logistics company depending on the characteristics of the product and supply chain from the viewpoint of Korean manufacturing companies. For this purpose, previous studies that presented factors for selecting third-party logistics companies were reviewed. As a method of integrating the presented selection criteria, 4 items of ‘logistics service’, 3 items of ‘logistics information (IT) system’, 4 items of ‘logistics price (cost)’, 5 selection criteria of 3 items of ‘Corporate Reputation’ and 6 items of ‘Capacity and Infrastructure’ and 20 application items were selected. And using these contents, a survey was conducted on manufacturing companies.
 Survey results As a questionnaire that can be used for AHP analysis, 51 companies in the efficient supply chain group and 35 companies in the reactive supply chain group were collected. The priority and weight of the selection criteria and application items were determined by performing pairwise comparisons on Tier II selection criteria and Tier III application factors, and calculating overlapping weights.
 The priority and importance of the Tier II selection criteria and the Tier III application factors were confirmed, and the weights for the selection criteria and application items that should be applied preferentially were calculated by synthesizing them. In the efficient supply chain group, the importance of stability, service price, image, cost reduction, accuracy, financial stability, and compatibility was high. In the reactive supply chain group, the importance of stability, accuracy, image, service price, information capability, compatibility, and incentives was high. Through these research results, by reflecting the characteristics of product manufacturing and supply chain, selection criteria and application items that should be applied first when manufacturers select third-party logistics companies are clearly presented.

EU27 regional trade networks for medical products in fight against Covid-19 pandemic: Quantifying vulnerability and self sufficiency in critical inputs.

The Covid-19 pandemic spread fast due to a lack of vaccines and a severe shortage of medical products to treat and combat the disease. Many studies have focused on the characteristics of extant global supply chains and trade networks that are determined by globalization drives for production to low-cost countries and the technological complexity of products with many components distributed globally. This, along with the lockdown of many sectors and national policies that divert exports for domestic use, are reasons for lack of access, especially, in Western countries to these products. Governments adopted policies that aim to mitigate vulnerability to imports of critical medical products that include self-sufficiency measures such as increased domestic production, stockpiling and reduction of exports. However, there is as yet no quantitative way to assess if a country's vulnerability to critical imports has been reduced by such drives for self-sufficiency, when other countries in the trade network follow similar policies. For this we develop a Google PageRank style centrality measure based on the Markose-Giansante eigen-pair method for a specially constructed global bilateral trade network to assess the vulnerability of net importers of critical medical products when they attempt to mitigate it by regional or domestic buffers. We use the network vulnerability centrality measure to quantify the regional self-sufficiency for EU27 countries over 2019-2021 for four Covid-19 critical medical products, viz. facemasks, personal protective equipment, ventilators and hand sanitizers. Despite, growth in value and share of intra-EU regional trade in most of these products by 2021, some countries did not achieve the reduction of vulnerability centrality.

Service-oriented supply chain: what do we know about its risks?

ABSTRACT This study identifies the risks entailed in a service-oriented supply chain. By employing supply chain mapping, contingency, and Risk Breakdown Structure (RBS) theories to elaborate a picture of the current knowledge, we were able to summarise and categorise the various risks into three main levels of cause. Next, these literature-based risks were narrowed down into a specific industry context and were then tested and confirmed using exploratory factor and confirmatory factor analyses to form an industry-oriented RBS for the construction business. The data were collected from 195 firms who participated in a large-scale survey sponsored by the Japanese Government to promote sustainable socio-economic development for the ASEAN region. As a result, seven risk categories related to demand, supply, operations, information, finance, time (delays) and external sources (human-made or natural-related) were identified and will be a valuable reference for researchers and practitioners. Furthermore, the relationship between identified risk and supply chain performance was explored. This paper is the first to introduce the concept and characteristics of a service-oriented supply chain by using a systematic review combined with a bibliometric mapping of the literature and an empirical study to generate both generic and industry-oriented RBSs in a single study.

Digital capabilities to manage agri-food supply chain uncertainties and build supply chain resilience during compounding geopolitical disruptions

PurposeThe agricultural supply chain is susceptible to disruptive geopolitical events. Therefore, agri-food firms must devise robust resilience strategies to hasten recovery and mitigate global food security effects. Hence, the central aim of this paper is to investigate how supply chains could leverage digital technologies to design resilience strategies to manage uncertainty stemming from the external environment disrupted by a geopolitical event. The context of the study is the African agri-food supply chain during the Russian invasion of Ukraine.Design/methodology/approachThe authors employ strategic contingency and dynamic capabilities theory arguments to explore the scenario and conditions under which African agri-food firms could leverage digital technologies to formulate contingency strategies and devise mitigation countermeasures. Then, the authors used a multi-case-study analysis of 14 African firms of different sizes and tiers within three main agri-food sectors (i.e. livestock farming, food-crop and fisheries-aquaculture) to explore, interpret and present data and their findings.FindingsDownstream firms (wholesalers and retailers) of the African agri-food supply chain are found to extensively use digital seizing and transforming capabilities to formulate worst-case assumptions amid geopolitical disruption, followed by proactive mitigation actions. These capabilities are mainly supported by advanced technologies such as blockchain and additive manufacturing. On the other hand, smaller upstream partners (SMEs, cooperatives and smallholders) are found to leverage less advanced technologies, such as mobile apps and cloud-based data analytics, to develop sensing capabilities necessary to formulate a “wait-and-see” strategy, allowing them to reduce perceptions of heightened supply chain uncertainty and take mainly reactive mitigation strategies. Finally, the authors integrate their findings into a conceptual framework that advances the research agenda on managing supply chain uncertainty in vulnerable areas.Originality/valueThis study is the first that sought to understand the contextual conditions (supply chain characteristics and firm characteristics) under which companies in the African agri-food supply chain could leverage digital technologies to manage uncertainty. The study advances contingency and dynamic capability theories by providing a new way of interacting in one specific context. In practice, this study assists managers in developing suitable strategies to manage uncertainty during geopolitical disruptions.

ENTRENCHING SUPPLY CHAIN RESILIENCE BEYOND BOUNDARIES: A DYNAMIC FRAMEWORK IN POST-COVID LANDSCAPE

The unprecedented global impact of the COVID-19 pandemic has heightened the critical significance of supply chain resilience (SCR) within the contemporary supply chain landscape. The body of literature dedicated to SCR has significantly expanded since the early 2000s, with numerous scholars delving into the construction of SCR frameworks based on empirical studies and literature reviews. Despite the usefulness of these frameworks, there has been a notable absence of a generic framework that transcends industry and national boundaries, particularly in light of the disruptive events triggered by the COVID-19 crisis. This study employs the narrative literature review method to intricately integrate itself into the existing SCR literature, conducting a comprehensive analysis, identifying theoretical foundations and empirical discoveries, and synthesizing this knowledge into a cohesive and all-encompassing structure to formulate a conceptual framework for SCR. This generic framework is designed to accommodate the unique characteristics of various supply chains. While the empirical validation of this innovative framework remains pending, it presents a valuable opportunity for scholars to engage in scientific investigations on SCR, building upon the collective insights of their predecessors. Moreover, practitioners can leverage this framework to scrutinize and construct resilient supply chains capable of withstanding future disruptions.

Greenhouse gas emissions of rice supply chain in China: From production to trade

Affected by climate change, food systems face enormous challenges of mismatch between competition for resources and nutritional demands. More than one third of food system emissions come from pre- and post-production. Research on emissions from food supply chains is crucial for building sustainable food systems and mitigating climate change. Rice is a major staple crop for mitigating emission risks in the food system. Based on the GHG emission accounts of rice supply chain in China from 2000 to 2020, this study analyzes the emission characteristics of rice supply chain during production, consumption, and trade, then elucidates the inter-regional transfers and inter-sectoral flows of rice emissions. This study found that non-CO2 GHGs at the production side contributes 78.56 % of total emissions of rice supply chain. Emissions of rice supply chain showed a promising downward trend of China, with the gravity center moving northward. Emission risks of inter-regional transfers were lower in the middle and lower reaches of the Yangtze River Plain, while higher in the Northeast China Plain. Emissions of inter-sectoral flows predominantly manifest within the agriculture sector in the major rice producing areas or between the agriculture and its downstream sectors. Accordingly, this study concludes potential paths contributing to emission reduction along rice supply chain of China by improving the relationships of production and inter-sectoral and inter-regional trade. This study can provide references for building sustainable food systems under climate change.

MARLIN Method: Enhancing Warehouse Resilience in Response to Disruptions

Background: Endogenous and exogenous factors impact the operational characteristics of supply chains, affecting wholesale warehouses. The survival of a warehouse is often threatened by disruptive events that alter infrastructure and performance. The emergence of COVID-19 exemplified the need for adaptability in retail goods supply chains, emphasizing the necessity for responding to external shocks. Methods: The MARLIN (Method wArehouse ResiLience dIstruptioN) method, founded on theories and models of resilience engineering is introduced. MARLIN is a practical tool designed to identify key areas requiring intervention in response to disruptive events. An empirical test was conducted in an Italian warehouse. Results: The conducted test yielded tangible results, demonstrating the efficacy of the method. It successfully pinpointed areas necessitating intervention and identified Key Performance Indicators (KPIs) associated with disruptions. The study not only underscores the importance of data collection but also highlights the often-overlooked significance of warehouse management. Conclusions: The study establishes MARLIN as a valuable asset for stakeholders involved in disruption management. Its application has proven instrumental in recognizing areas of intervention and identifying KPIs related to disruptions. Ongoing research endeavors to broaden its applicability across diverse supply chain scenarios, aiming to enhance situational awareness and enable proactive risk assessment through what-if analysis.

Drivers of consumer protection practices: implications for operational performance

PurposeGlobalization and increased outsourcing have contributed to increased supply chain complexity, exposing firms to greater vulnerability in the areas of product safety and supply chain security. Meanwhile, stakeholders pressure firms to ensure that their products are safe, and their supply chains are secure. Drawing from stakeholder theory, this paper aims to explore how the supply chain characteristics of distance and power affect the adoption of consumer protection (CP) practices, which ensure product safety and supply chain security.Design/methodology/approachUsing primary survey data from a sample of Canadian manufacturing firms, this research examines the relationships among supply chain characteristics, adoption of CP practices and firm performance.FindingsAnalysis supported the use of two practices related to product safety (consumer education and product design) and three practices for supply chain security (packaging, tracking and authenticity). Greater cultural distance between the focal firm and its suppliers was positively associated with investments in safer design practices, while increased geographical distance between the focal firm and the customer was significantly related to increased consumer education. Moreover, as power of a focal firm relative to its suppliers increased, so too did investments in supply chain security. Finally, CP practices were related to improved operational performance along multiple dimensions.Originality/valueThis research focuses on the critical role of two key stakeholder groups in improving product safety and supply chain security: suppliers and customers. The authors add to the theoretical discussion of product safety and supply chain security by identifying critical differences between suppliers and customers for the focal firm. Second, the research informs the managerial community of the potential benefits of investments in CP practices.

Research on the Influencing Factors of Sustainable Supply Chain Development of Agri-Food Products Based on Cross-Border Live-Streaming E-Commerce in China.

The organization and coordination of cross-border e-commerce platforms in agricultural product trading are continuously increasing, and the involvement of digital platforms has driven the integration and development of cross-border agricultural product supply chains with live-streaming e-commerce, effectively facilitating the comprehensive development of producers, sellers, and professional service providers within the ecosystem. However, despite the growing importance of this integration model in the market, there are still numerous unresolved issues from a supply chain perspective, and existing research provides relatively limited guidance on the effective operation of this integrated supply chain model. To address this gap in theoretical research, this study first delves into the essence and fundamental characteristics of sustainable cross-border agricultural product supply chains in the context of live streaming. Secondly, employing grounded theory as the primary research method and combining platform theory and ecosystem theory, an influencing factor system and an impact model for the development of sustainable cross-border agricultural product supply chains in the context of live streaming are constructed to gain a more comprehensive understanding of the complexity of this integrated supply chain model. Finally, from the perspectives of government agencies and practitioners, development pathways for sustainable cross-border agricultural product supply chains in the context of live-streaming e-commerce are proposed, aiming to enhance existing research and provide decision-making support for relevant stakeholders in formulating development strategies. The findings of this study contribute to expanding the research perspective on the ecosystem of live-streaming e-commerce and sustainable cross-border agricultural product supply chains, providing theoretical support for the establishment and operation of sustainable cross-border agricultural product supply chains in the context of live streaming. Additionally, it offers important references for promoting the sustainable development of live-streaming e-commerce and cross-border agricultural product supply chains, facilitating industry upgrading, global agricultural trade, and achieving mutually beneficial outcomes.

Assessing the supply chain management of waste-to-energy on green circular economy in China: an empirical study.

One of the industries that makes a significant contribution to the overall amount of greenhouse gas emissions around the globe is agriculture. In this regard, the use of bioenergy in the agricultural and food processing industries might benefit from the implementation of circular economy techniques. Despite the fact that just roughly 9% of the global economy is circular, there have been worldwide efforts to improve that reality. The linear economy, commonly known as the "take-make-use-dispose" model, is in sharp contrast to the circular economy, also known as "grow-make-use-restore," which seeks to influence the flow of materials and energy in order to maximize the benefits to the environment and minimize any associated costs. Garbage-to-energy, also known as WTE, is the focus of both academics and businesses as a direct result of the increasingly diminishing number of energy supplies and the ever-increasing amount of garbage. This project intends to turn trash into profit, lessen the impact waste has on the environment, and generate energy from biowaste by conceptualizing a focus on the supply chain characteristics of waste-to-energy processing. The adoption of a waste-to-energy (WTE) supply chain as a district energy system should be a viable solution toward a circular industrial economy that can solve energy consumption, waste management, and greenhouse gas emission concerns all at once. In the framework of a "circular economy," this study investigates how the management of waste-to-energy supply chains impacts the performance of businesses. The present investigation makes use of life cycle assessments, technical innovation, waste-to-energy conversion, and capacities related to circular economies. The study makes use of data obtained from an online survey that was administered between March 2021 and November 2021 to employees of 285 representative samples drawn from 457 European enterprises and firms that have accepted the concepts of the circular economy. The data is examined using a technique known as partial least squares structural equation modeling (PLS-SEM for short). The findings indicate that waste-to-energy serves as a mediator between the life cycle assessment and the capabilities of the circular economy and that sustainable supply chain management, sustainable supply chain design, technological progress, and waste-to-energy all have positive effects on these metrics.

Discerning the supply chain of Bumiputera entrepreneurs in the Malaysian wood products and furniture industry: Status, challenges, and remedial measures

Supply chain management has been identified as the major constraint on the growth of Bumiputera entrepreneurs in the Malaysian wood products and furniture sector. Therefore, a study to examine the characteristics of supply chain among Bumiputera entrepreneurs in the wood industry registered with the Malaysian Timber Industry Board was conducted. The results revealed that most of the respondents were micro- and small-sized enterprises, with a sales focus on the domestic and contract-market. They were predominantly wooden furniture manufacturers, who had a relatively low level of knowledge about supply chain management. The respondents also indicated that their major challenges include lack of finances, small volume of production, and the lack of government support. The factor analysis and regression analysis conducted revealed that for Bumiputera entrepreneurs to gain better supply chain management they need to improve their frequency of engagement, trust, culture, and maturity with their supply chain actors and partners. The results of this study are unique, as it implies that policymakers should take heed of improving supply chain management, to reverse the flagging fortune of Bumiputera entrepreneurs in the Malaysian wood products and furniture sector.

Development of freight trip generation model using observed and unobserved information of supply chain characteristics for a sustainable urban transformation

Supply Chain Characteristics (SCC) drive the city logistics to control the economic activities that support urban life and transformation. The dynamics of freight trip activity and SCC in city logistics are less understood by city planners, disrupting the prediction of urban Freight Trip Generation (FTG) models. To develop robust urban FTG models, the present study introduces the concept of estimating the freight trip activity using observed and unobserved (subjective) information of SCC for sustainable urban transport movement. Traditionally, the objective variable excludes the unobserved information of SCC while developing the FTG model; this gap can be addressed by incorporating subjective variables to measure both observed and unobserved information of SCC. A unique framework was designed by a combination of objective and subjective variables through Exploratory Factor Analysis (EFA) and Structural Equation Modelling (SEM) to estimate the freight trip activity. An Establishment Based Freight Survey (EBFS) collected from an Indian smart city (1793 samples) comprising various SCC was used to test the developed framework. Deployed EFA can identify the subjective variables using latent constructs to explain the observed and unobserved information in the SCC. Then, sequential execution of SEM with hypothesis path structure for estimating the freight trip activity. The direct, indirect, and total effects of the FTG model revealed added advantage of causal inter-relationship of urban freight trip activity and SCC between intermediate and pure receiver establishment. The developed FTG models using observed and unobserved information of SCC predicted freight trip activity with an accuracy of 57% for intermediate and 63% for pure receiver establishment. The effect of SSC on freight trip activity aids in creating sustainable urban freight transportation that could be an agile, responsive, and flexible adaptive system for the global market demand.

IMPLEMENTING NEW SUPPLY CHAIN MANAGEMENT PRACTICES TO IMPROVE INDUSTRIAL PRODUCTIVITY AMID THE COVID-19 PANDEMIC

This study aimed to develop a methodological approach to assessing the major directions for introducing new supply chain management (SCM) methods to improve the industrial enterprises’ productivity during the COVID-19 pandemic and test the developed approach at enterprises in the real economy related to Russia, Kazakhstan, and Azerbaijan. To this end, a comprehensive research project needed to be implemented to assess the main prospects for implementing new SCM practices. The objective was to boost the productivity of the enterprises in the context of the pandemic and identify the main problems hindering the sustainable development of such chains. The testing identified the principal characteristics of supply chains amidst the pandemic, namely reliability (30 experts spoke in favor), resilience (22), and economy (19). At the same time, a sharp decrease was observed concerning the interest in the enterprises’ supply chains optimization (7 experts), flexibility (6), efficiency (2), and environmental friendliness (4). The most promising technologies for the development of supply chains, according to the results of the study, should be considered the Internet of things (µ = 3.8), additive manufacturing (3D printing) (µ = 3.77), big data analytics (µ = 3.73), and blockchain and virtual reality (µ = 3.6 each).

The Circular Economy Potential of Spent Hens’ Co-Products and By-Products in Italy by Material Flow Analysis

Eggs represent one of the most consumed animal products worldwide. In Europe, over 366 million laying hens and 6.1 Mt of derived eggs have been estimated in 2020, and Italy represents the fourth largest producer (41 million hens and 0.79 Mt of eggs). Egg production has been identified as relatively environmental-friendly, but several environmental concerns have been recently raised considering the inefficient spent hens’ management. Spent hens are generally euthanized and composted or incinerated, producing greenhouse gases while at the same time significant nutrients are lost. First, the research reviews the egg supply chain characteristics and the alternative spent hens’ valorization pathways. Then, using the material flow analysis, the research quantifies and qualifies the consistencies of laying hens and protein content included in spent hens across Italy, providing a comprehensive assessment of the national scenario under an environmental and circular perspective. Furthermore, the research develops an inventory of the spent hens’ co-products and by-products in Italy, focusing on the flows of proteins for further environmental studies. The research has highlighted that over 13,948 t of proteins could be extracted, distinguishing between those embedded within offal, feathers and blood. In addition, spent hens can be used for human consumption, as well as for material or energy recovery through anaerobic digestion or microbial fermentation. Results are addressed to farmers, who are required to boost their environmental performances, and public authorities, who must implement sustainable strategies to collect spent hens.

The impact of carbon neutrality policies on the stock market from a supply chain perspective

PurposeThis study explores the impact of carbon neutrality policies on Chinese stock market from a supply chain perspective. Specifically, the carbon policy refers to the Action Plan for Carbon Dioxide Peaking Before 2030 (the Plan) in China.Design/methodology/approachThis paper is based on the resource dependence theory (RDT) and applies the event study methodology to explore the impact. It uses the cross-sectional regression model to reveal the moderating effect of supply chain characteristics on the stock market reaction with a data set of 354 listed companies in A-shares (excluding ChiNext and SME board).FindingsThe promulgation of the Plan shows a significant negative stock market reaction. Customer concentration, out-degree centrality and smart supply chains (SSCs) have a significant negative moderating effect. In-degree centrality and supplier concentration have a significant positive moderating effect. Furthermore, the conclusions concerning out-degree centrality, supplier concentration and SSCs are counterintuitive.Practical implicationsFor policymakers, the study results provide a reference for evaluating the carbon neutrality policy. For managers, this study provides theoretical support for strategically adjusting and designing supply chain structures in the context of advocating peak carbon dioxide emissions and carbon neutrality.Originality/valueThis paper is the first attempt that includes the supply chain structure factors into the impact of carbon neutrality policies on the stock market.
