“…Many definitions of food waste (e.g. leftovers, food loss and unconsumed foods) challenge the quantification of the phenomenon (Betz et al , 2015), which also means that each type of food waste may require specific effective interventions (de Oliveira Pontes et al , 2022). Specifically, limited studies on plate waste in a restaurant setting (Dolnicar et al , 2020) show that there is a need to address waste from dining out spurred by busy lifestyles of urban population (Huang and Tseng, 2020).…”

Purpose The global food waste and food scarcity paradox is steadfastly increasing. This study aims to examine the effects of digital nudging as forms of positive and negative reinforcement to change food waste behavior and found that nudging positive reinforcement modifies this habit. Design/methodology/approach A field experiment was conducted on 628 diners randomly split into experiment (n = 412) and control group (n = 216) in two separate dining locations over four weeks. Out of these, 412 diners were randomly subjected to tent cards with positive (n = 228) and negative (n = 184) reinforcement nudging and completed a questionnaire to ascertain if nudging affects their consumption behavior. Consumption waste per unit revenue was calculated from all 628 diners individually to analyze the financial impact between control and experiment groups. Findings SEM analysis reveals that positive reinforcement mediates between external motivators (social media and restaurant service) and reduction of food waste behavior. Further analysis also reveals that nudging has a higher three times effect on reducing food waste as compared with no nudging (control). Social implications Positive messaging encourages behavior change more effectively as compared to negative ones. Gentle reminders of how everyone can personally be a “warrior” or “hero” in the fight against global food waste increases the likelihood of altruistic motivation in tackling these issues. Originality/value This study demonstrates how positive reinforcement in the form of nudges acts as key mediator to support reduction of consumer food waste on site, ultimately helping to reduce financial costs compared to those without nudges.

The circular economy (CE) has gained global attention for its potential to promote sustainable production and consumption through continuous growth and the efficient use of resources. Despite several reports highlighting its benefits, there is still a lack of concrete and proven studies examining the importance of institutional pressures for the transition towards CE in food supply chains. This study aims to address this gap by conducting a Systematic Literature Review (SLR) to identify the drivers and barriers to the institutionalisation of CE in food supply chains, and to propose practical and managerial implications for achieving this transition through institutional pressure. We reviewed 25 studies and conducted a descriptive analysis of papers per year and journal, followed by a categorical thematic analysis. The results indicate that normative pressures were the most frequently identified among the different institutional pressures, followed by mimetic and coercive pressures. Therefore, promoting CE in food supply chains may require the implementation of laws, policies, and strict governance to reduce risks. This paper contributes to the existing literature and provides valuable insights for researchers and practitioners interested in the transition towards a CE in food supply chains.
