Purpose: The purpose of this paper is to review, through a systematic literature review, the different perspectives from which imperfect, ugly and suboptimal food products lead to food waste, as well as to ascertain which are the already proposed improvements, and to present further solutions to develop more sustainable food production and consumption.Design/methodology/approach: A systematic literature review was conducted using PRISMA methodology and searching for the following keywords: “imperfect fruit”, “imperfect food”, “ugly fruit” and “ugly food”; the review was carried out within three databases (Emerald, Scopus and Science Direct-Elsevier), starting, since the topic is quite recent, from the first published article on this issue. Only peer-reviewed papers were selected.Findings: Results reveal that, among 188 papers, only 49 fit the aim of the literature review, analysing what strategies can be used to ameliorate consumers' perception of suboptimal food in order to fight food waste. Specifically, four different interventions are suggested: on the supply chain, on personal experience and awareness campaigns, on promoting circular economy, and on marketing and advertising campaigns.Originality/value: This paper fills a gap in literature since, by the authors' knowledge, this is the first literature review which analyses different strategies on food waste reduction linked to imperfect/suboptimal food, suggesting further steps which may be taken.

Purpose: The purpose of this paper is to investigate, through a quantitative research, the impact of the COVID-19 pandemic on online food delivery in Italy and Poland, as well as to ascertain whether or not, under a consumer perspective, respondents consider such method as impacting on the environment and on food waste.Design/methodology/approach: An empirical survey of consumers at Italian and Polish Universities was conducted using the online survey computer-assisted web interview (CAWI) method.Findings: Results reveal that the COVID-19 pandemic has modified consumer habits in both Italy and Poland, though the researched sample does not have full knowledge of these changes. Moreover, the study has proved once again that online food delivery may impact negatively on the environment and the food waste issue.Originality/value: This paper fills a gap in literature since, by the authors' knowledge, it is the first quantitative study analysing Italian and Polish young consumers as to online food delivery habits and their approach to sustainability aspects of this purchasing method.

This research paper explores the role of environmental labelling in shaping the purchasing and consumption behaviours of Generation Z. The study aims to provide insights into the comprehension, perception, and attitude of this generation towards environmental labelling and to investigate how these factors impact their purchasing decisions. The results of this study provide valuable insights into the role of environmental labelling in shaping the behaviours of young consumers and suggest that it still matters to this generation. The study also highlights the importance of trust in environmental labelling for influencing purchasing decisions. Our research paper provides new insights into the role of environmental labelling in shaping the behaviours of Generation Z, which is a critical demographic group for sustainable consumption. We found that this generation is highly aware of environmental issues and is motivated to make eco-friendly purchasing decisions. However, our study also highlights that the lack of trust in environmental labelling can be a significant barrier to sustainable consumption. This study contributes to the literature on environmental labelling and consumer behaviour among Generation Z.
