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.

Abstract:Glass manufacturing is a high-volume process, during which large substance quantities are transformed into commercial products, and significant amounts of non-renewable resources and energy (i.e., thermal fuels and electrical power) are consumed. The main purpose of this study is to give a critical explanation of the performance of the Italian container glass industry from the perspective of cullet being recycled, to outline the opportunities for transition towards circular business models that stimulate innovation in new sectors based on reverse-cycle activities for recycling. In 2015, disparate performances have been achieved as regards the container glass recycling rate in northern, central, and southern Italy, accounting for around 73%, 64%, and 55%, respectively. In fact, only northern Italy is in line with European targets, as by 2025 it will only need to increase its current performance by two percentage points, unlike central and southern Italy that will have to increase performance by, respectively, 11% and 20%. This shows a need to improve the efficiency of municipal waste collection systems in central and southern Italy, where undifferentiated waste still holds appreciable amounts of glass. Consequently, we propose several improvement channels, from the revision of waste legislation to the re-engineering of waste management supply chains.

PurposeThe aim of this paper is to map and analyse the state of the art of eco‐energy labelling and its potential as a fundamental component in the transition process towards eco‐sustainability.Design/methodology/approachA detailed scenario of trends in eco‐energy labelling systems, both on an international and European Union scale are outlined, followed by identification and analysis of the key representative experiences. Subsequently, the main constraints that limit their full potential as a benchmark and tool of improved customer communication for environmental sustainability have been highlighted and critically analysed.FindingsThe full implementation of eco‐energy labelling, as a authentic driving force in sustainability building processes, requires the elimination of the critical factors identified. Therefore, standardisation of benchmarking methodologies, based on improved customer information mechanisms regarding qualitative and quantitative indicators, need to implemented. A strong commitment on the part of all participants involved, to define a multi‐level framework, capable of promoting a recognised international rating scheme in needed.Practical implicationsThe most significant implications regard the attempt to classify and coordinate all the information concerning instruments, initiatives, policies and strategies related to eco‐sustainability.Originality/valueThe paper is a contribution towards pinpointing the current fragmented scenario of eco‐energy labelling tools with the aim of re‐conducting them into a coherent and more functional whole.

PurposeThis paper investigates circular economy communications and stakeholder dialogic engagement with circular economy posts published by European agri-food companies on Twitter from the spread of the COVID-19 pandemic. It explores the use of social media as a dialogic tool to activate circular economy engagement in order to involve all supply-chain actors on the route to a circular transition.Design/methodology/approachA coding framework based on the reclassification of the Glossary of Circular Economy, according to a 4-R paradigm (reduce, reuse, recycle and recover), was developed for the analysis. All tweets published by a sample of European agri-food companies, starting from the start of the COVID-19 pandemic until data extraction, were collected, purified and analysed.FindingsAgri-food companies showed a higher level of engagement through social media, even if mainly focused on “recycling” and “general circular economy” issues. In general, awareness among social network users of the need to be part of the circular economy transition emerged. Moreover, the highest percentage of posts published by the companies' Twitter accounts was informative rather than interactive. In addition, starting with the COVID-19 pandemic crisis, the circular economy has arisen as a central topic of debate and a driver for the rethinking process of the agri-food business community.Originality/valueTo the best of the authors' knowledge, this research represents the first study focused on circular economy engagement through social media from the company perspective in the agri-food industry.
