      Liakos, N., Kumar, V., Pongsakornrungsilp, S., Garza-Reyes, J.A., Gupta, B., Pongsakornrung-silp, P.; University of Derby (Emerald, 2019-06201)
      Circular Economy (CE) has evolved as a result of the growing environmental awareness, environmental legislation and the need for social responsibility. However, awareness levels of CE are not as high as expected and practices are further behind than they should be, with a significant lack of research around the subject in the literature. This study therefore attempts to examine the current state of awareness levels and the practices around CE in manufacturing firms. Moreover, the study aims to empirically validate one of the earlier proposed CE models. The study adopts a quantitative survey questionnaire based approach. More than 500 people from various manufacturing organisations were contacted directly over a 40-day long sampling process through the FAME database, personal contacts and LinkedIn. The survey resulted in 103 completed responses. Given the exploratory nature of the study, the data was mainly analysed using descriptive statistics. To validate the CE model, a correlation analysis was also conducted. The research findings show that with the growing emphasis on CE across the globe by governing bodies, firms are becoming more aware of CE practices. The analysis also shows some useful insights on the state of each of the pillars (economic benefits, environmental impact and resource scarcity) of CE. Our findings also indicate that the environmental impact pillar of CE is at a more developed state than the other two pillars which are –mostly- in a research state. Research Implications and Limitations: The study provides manufacturing firms with a thorough understanding of the state of CE practices and importance of its successful implementation. The findings of the study advocates consideration of all three pillars of CE by managers as a guide to plan for an efficient strategy around CE implementation. Moreover, our study adds to existing efforts by the academic community to raise the awareness towards CE practice among all relevant stakeholders. The findings of this study are based on the responses from a limited 103 survey responses from manufacturing firms. Originality/value: This study adds to the very limited empirical literature on CE awareness and practices in manufacturing firms. This is also one of the first studies attempting to empirically validate an existing CE model.

      Rocha-Lona, Jose Arturo L., Cuevas-Zuñiga, I.Y., Soto-Flores, M.R., Garza-Reyes, J.A., Kumar, V.; University of Derby (IEOM Society, 2019-07)
      There is little research documenting the use of clean technologies (CT) in Agribusiness in Mexico. In this regard, the objective of this article is to provide an in-depth literature review that can cover this gap and help decision-makers and investors to identify opportunity areas in the industry. It also provides a good theoretical background for researchers and practitioners to further investigate applications of clean technologies in this sector or other potential ones. To conduct this research, an in-depth analysis of the literature on clean technologies and their use by agribusiness in Mexico was carried out. The databases such as Web of Science, Scopus, and Springer were used to identify the relevant international journals in the field and their research-contributions. The main results show that there is a need for financial investments on clean technologies CT that can help optimizing processes and products on the sector. The results also showed that CT is mainly used to minimize energy consumption, to optimize planting and harvesting, to enhance irrigation and water use, and to maintain the soil fertility. Despite these wide applications, the authors found that the penetration of CT is still low and policy-strategies are required with effective financial investments in the sector.

      Gollotta, Bruno; Kolelas. Vidrene; Garza-Reyes, Jose Arturo; Anosike, Anthony; Kumar, Vikas; University of Derby; University of the West of England (Industrial Engineering and Operations Management (IEOM) Society, 2017-07)
      Biomass represents approximately 10% of the energy sources in the world. The most common use of biomass for energy is direct combustion, gasification, carbonization and pyrolysis. In this perspective, torrefaction emerges as a thermal biomass pre-treatment method that has an ability to reduce the major limitations of biomass, such as heterogeneity and lower energy density. However, one of the outputs from the torrefaction process is a pyrolysis condensate (tar). Tar is brown or black liquid composed of hydrocarbons which can cause clogging and fouling of pipes, heat exchangers or particulate filters. This paper provides a study performed in a biomass power generation company that was producing an excess of tar. In order to provide a solution to the excess tar generated, a framework to implement sustainability business processes using the Business Process Management (BPM) approach was used. The study found two solutions for the issue (short- term and long-term scenarios) using tools to improve the process management by focusing on sustainability.
    • Using entropy and AHP-TOPSIS for comprehensive evaluation of internet shopping malls and solution optimality

      Consumers are switching from offline to online to buy everything due to this reason nowadays Internet shopping malls (ISMs) are setting up a very crucial role in the economy. For assessment and ranking are basically a critical work which could be exploitation of Internet shopping malls information resources when consider in a scientific way, there are many methods for the evaluation and ranking of e-commerce sites. Taking into consideration Traffic Rank, Inbound Links, Competition, Speed, and Keyword Statistics, in literature Multi Criteria Decision Making (MCDM) methods are rarely used by the researchers to find the rank of Internet Shopping Malls (ISMs) on the basis of primary/secondary data of these influencing factors. This study, therefore, is unique to narrow down the gap in literature by employing MCDM methods i.e. Entropy and Analytic Hierarchy Process (AHP) to collect the weight of influencing factors and Technique for Order Preference by Similarity to Ideal (TOPSIS) to find the rank of Internet Shopping Malls (ISMs). After finding out the rank of selected criteria, solution optimality needs to be done to find the average ideal solution matrix. Conclusion and managerial implications of the study are also discussed.
    • Using Fuzzy Delphi and Generalized Fuzzy TOPSIS to Evaluate Technological Service Flexibility Dimensions of Internet Malls

      Kumar, Anil; Dash, Manoj Kumar; BML Munjal University; Indian Institute of Information Technology & Management, Gwalior (Springer, 2017-02-20)
      The expanding development of technology and availability of the internet is leading a consumer shift from offline to online activity. This shifting behavior shows positive signs for the growth of the e-commerce market but also increases the challenges for the online service provider to provide satisfaction and loyalty to consumers when there is no personal interaction between buyer and seller. In these circumstances, quality, in terms of technology services i.e. web/transaction, can play a significant role for the service provider, especially for internet shopping malls. But there is little material available in current literature to build a theoretical model for web/transaction flexibility dimensions and to rank internet shopping malls on their provision of services to customers. The vagueness of the available information can be tackled by fuzzy theory by employing a Fuzzy Delphi method to finalize technological service dimensions and lead to development of a research model. The final ranking of internet malls has been achieved by utilizing Generalized Fuzzy TOPSIS. The findings of this study can be useful for internet shopping malls in devising strategies to provide a better quality of web/transaction service to customers.

      Gallotta, Bruno; Garza-Reyes, Jose Arturo; Anosike, Anthony; University of Derby (IEOM Society, 2018-03)
      The paper provides a Delphi study to verify the framework to implement sustainability initiatives in the business processes. The Delphi technique seeks to obtain consensus on the opinions of experts, termed panel members, through a series of questionnaires. As part of the process, the responses from each round are fed back in summarized form to the participants who are then given an opportunity to respond again to the emerging data. The study successfully obtained a consensus in the phases and steps of the conceptual framework and provided feedback from the specialists. According to them, leadership, people and cost were identified as the main challenges related to the sustainability adoption by the organisations and key performance indicators (KPIs), Lifecycle assessment (LCA) and triple bottom line (TBL) were identified as the main methods to assess al the sustainability dimensions in terms of business processes.

      Kumar, Anil; Zavadskasb, Edmundas Kazimieras; Mangla, Sachin Kumar; Agrawal, Varun; Sharma, Kartik; Gupta, Divyanshu; University of Derby; Vilnius Gediminas Technical University; University of Plymouth; BML Munjal University (Taylor & Francis, 2018-11-19)
      The pharmaceutical industry is very important in delivering life-saving products/services to society. There are many ways for materials/products/services concerned with pharmaceuticals to influence the environment; these include improper disposal of pills/tablets by patients, expired and unused medications, improper release of drugs by pharmacies or household sewage mixed with surplus drugs. In view of this, the present work seeks to integrate green supply chain (GSC) concepts in the pharmaceutical sector in a developing economy Indian context. In so doing, managers need to determine the potential risks in adopting GSC initiatives to achieve sustainability in operational perspectives. In this sense, this work seeks to distinguish the potential risks in adopting GSC initiatives within the pharmaceutical industry. This work uses a literature review and fuzzy Delphi approach in finalising the risks. This research also uses fuzzy Analytical Hierarchy Process (AHP) for prioritisation of the risks under vague and unclear surroundings. According to the findings, cold chain technology and supply risks categories are highly prioritised. This work can assist practising managers and government authorities in effectively developing and managing GSC initiatives in line with sustainable development goals in the context of the pharmaceutical industry. Finally, a sensitivity test is applied to evaluate the stability of ranking of risks.
