Social recipe recommendation to reduce food waste

Abstract

Little attention has been given to food waste prevention in households by changing consumers' behaviors. In this paper, we present a social recipe recommender which is a mobile application being developed to reduce food waste in households by recommending recipes to a group of connected people. The application will allow the logging of food and waste related daily practices and will persuade a group of users to share their food by recommending recipes based on available ingredients within this group. The method of data collection, persuasion and the experiments are described through this paper.

Food waste matters - The policy implications and sustainability of food waste practices

“…Few applications are available and provide practical ways in which one can extend shelf-life, food supply knowledge, planning, and grocery shopping education and recipes which one can use leftovers to create. Such applications include the British app "Love your Leftovers" and the German app "Zu Gut fur die Tonne" (Yalvac et al, 2014).…”

“…It was part of the REFRESH EU research initiative, which seeks to help Europe achieve its objective of decreasing food waste. The study has been conducted based on the strategies as follow: (1) social recipes, which refers to a community-based system of food sharing (Lim et al, 2014;Lim et al, 2017;Yalvaç et al, 2014); (2) eco-feedback, which refers to comparing one's own food waste behaviour to others (Lim et al, 2017); (3) apps and wearables, where different apps and a wearable camera were tested by consumers (Farr-Wharton, Foth & Choi, 2013;Farr-Wharton, Choi & Foth, 2014a;Ng et al, 2015;Hoem, 2017); (4) interactive or smart fridge, which aimed to help consumers organizing the food in their fridge (Rouillard, 2012;Farr-Wharton, Choi & Foth, 2014b;Nguyen et al, 2015); and (5) indirect and direct persuasion, where two variants of a recipe website were investigated in relation to consumer's environmental attitudes and their recipe choice (Aleahmad et al, 2008). The list of apps divided in different categories based on the main functionality that have been included in the study by Vogels et al (2018) not see an obvious need for such an app since they believed they did not waste much food.…”

Eco-Joy: Imagining Sustainable and Joyful Food Eco-label Futures

“…We posit that joy 1 may help consumers to find and maintain holistically meaningful ways to take action, thus promoting and sustaining pro-environmental efforts [25,47,56,61]. Tools that elicit positive emotions, such as feeling amazed, cheerful, proud, and hopeful, have been shown to be significant predictors of purchase intentions, and can increase the probability of making a purchase [17,48].…”

“…Joyful. Joyful interaction may increase consumer attention and responsiveness, and provide a powerful source of motivation to take action [27,35,45,61]. For example, stories and narrative transportation engage climate change action through emotional arousal, inciting pro-environmental behaviour [35].…”
