Over the last decade, the unsustainability of the current economic model, based on the so-called take-make-dispose paradigm, has emerged. In particular, the agro-food sector (AFS) has been severely affected by such problems as resource scarcity and food loss and waste generation along the supply chain. In addition, climate change and biodiversity loss have helped to define an imperative paradigm shift towards a circular economy. Recently, with the publication of Sustainable Development Goals (SDGs), the scientific research examining the adoption of circular economy (CE) models and tools has increased. In this context, the importance of shifting towards a circular economy has become urgent. In this paper, a systematic literature review (SLR) was performed to investigate the state-of-the-art research related to the adoption of circular economy models and tools along the agro-food supply chain. Furthermore, this review highlights that, due to the complexity of the agri-food supply chain, it is almost utopian to define a unique circular economy model for the whole sector. In addition, it emerges that future researches should be concentrated on the integration of different stages of the supply chain with circular economy models and tools in order to create a closed-loop agri-food system.

Abstract:The purpose of this work is to carry out a review of the main technical-economic and environmental implications associated with the production of photovoltaic (PV) energy, one of the renewable sources for the production of electricity which currently presents the highest rate of growth worldwide-particularly in Europe and in Italy. The review provides a detailed exploration of the most important initiatives taken at the national level for the end-of-life management of the modules, and highlights issues associated with the disposal and/or recycling of obsolete photovoltaic panels in terms of techno-economic and socio-environmental sustainability. The paper highlights the main critical elements and potential opportunities deriving from the technological, managerial, and organizational options available to enhance recovery and recycling rates of PV panels in Italy. Results point out the importance of a circular economy perspective, through the involvement and awareness of the actors in the process, in order to render an even greener photovoltaic energy life cycle.

PurposeThis paper investigates the extent to which the COVID-19 pandemic has accelerated service innovation in the restaurant sector. It explores the use of digital technologies (DT) as a safety-empowerment and resilient strategy in the food-service industry during the pandemic. It also investigates the impact of DT on customers' risk perception (CRP) and customers' intention to go to restaurants (CIR) in Italy.Design/methodology/approachBased on the theory of planned behaviour and perceived risk theory, this study investigates a sample of customers residing in Italy. Multiple regression and mediation analyses are conducted to test the research hypotheses, adapting the logic model developed. Using the bootstrapping technique, this study also explores whether the pandemic has moderated the relationship among several variables adapted from the literature. Robustness tests are also performed to corroborate the analysis.FindingsThe pandemic has accelerated the food-service industry's digital transformation, forcing restauranteurs to implement DT to survive. Findings show that DT support restauranteurs in implementing innovative services that reduce interactions and empower cleanliness among workers and customers, reducing CRP and preserving CIR. Thus, managing risk perception is helping the restaurant sector to recover.Practical implicationsPractical implications are presented for policymakers to catalyse the digital transformation in small- and medium-sized restaurants. The results may also be beneficial for entrepreneurs who can implement innovative service practices in order to reduce interaction and empower cleanliness levels. Moreover, academics can use these results to conduct similar research in other geographical contexts.Originality/valueThe present research represents the first study investigating the relationship between the use of digital technologies and the intentions of customers to go out for dinner during the ongoing pandemic in Italy.

Over the last few decades, stakeholders’ growing attention towards social and environmental issues has challenged universities’ traditional accountability boundaries, imposing the adoption of innovative reporting tools that facilitate stakeholders’ engagement in Corporate Social Responsibility (CSR) practices and performances. Against this backdrop, online communication tools, such as websites and social media platforms, have gained momentum as a pivotal means to increase dialogue with the myriad of stakeholders, especially during the pandemic period, as it has dramatically reduced physical interactions. Based on these premises, this study aims to dive deep into the use of social media to communicate CSR strategies in the university context by exploring the case of the University of Salerno. To this end, all posts published by the University of Salerno’s official Twitter account from 2015 to 2021 have been extracted and analyzed. Accordingly, the degree of interactions with stakeholders and the communication direction and balance level have been examined based on Carroll’s pyramid. Findings show a higher level of engagement for CSR posts and, in particular, for the philanthropic dimension. Results also highlight that, during the COVID-19 pandemic, the University of Salerno has empowered CSR disclosure through Twitter. The methodology adopted could be replicated for other universities to understand better how public universities use social media to involve a broader range of stakeholders in their CSR practices.

PurposeThis paper aims to explore how the Italian wine industry discloses corporate social responsibility (CSR) practices and quality certifications and the corresponding determinants via websites. The study also aims to investigate the relationship between CSR practices and financial performance. The information consistency between the quality certificates reported on corporate websites and official database statements is also explored. Lastly, the paper investigates how the relationship between the size of wineries and CSR disclosure changes according to firms' geographic location.Design/methodology/approachThis paper analyses CSR corporate communication via the websites of a sample of Italian wineries by adjusting the theoretical framework developed by Amran (2012) to the wine sector's peculiarities. Moreover, a cross-certification analysis and a moderation analysis were performed to fulfil the purpose of the research.FindingsThe analysis revealed the extensive use of CSR disclosure via websites. It was found that company size positively affects CSR disclosure and Quality Certification Disclosure (QCD), while geographic location slightly moderates the relationship between the two variables. In addition, a negative relationship between CSR disclosure and corporate financial performance and its reverse causality emerged. Moreover, for most wineries, information consistency between the quality certificates reported on corporate websites and official database statements was observed.Research limitations/implicationsThe study's main limitation is that the search process was performed during lockdown. Therefore, the examined issues could change in the near future due to the shift in priorities that the COVID-19 pandemic is determining.Practical implicationsThe results can help managers implement CSR disclosure and QCD practices to enhance stakeholder legitimacy and enable their companies to compete in strongly competitive international markets.Originality/valueThe paper represents the first study investigating online QCD and its consistency in the Italian wine sector.
