Food waste - the avoidable loss of edible products - has social, economic and environmentalimpacts. In the poorer nations food security is an issue while in thericher nations, the higher the national GDP, the higher the per capita food waste.Over half the food wasted in Europe occurs in the domestic/consumer section withthe majority of that going for composting which produces excess greenhouses gasses.This study targets the home user with a mobile device application called ‘FeastMe’that is aimed at reducing this domestic waste. FeastMe is designed to integratea pre-existing supermarket, BYOD, self-scan POS system with a novel, multi-user,‘family sync’, database driven storage system and a recipe module.The methodology used was to examine previous works in this sector and note theirshortcomings. These were then addressed in the application design. A barcode scanning,Android app was developed using a standard, iterative design cycle processusing paper prototypes and user feedback prior to building with the Ionic framework.The application backend was also built using Ionic, linking a Google Firestore/Firebasedata storage with the recipe module and the Android app. All communicationbetween these components was using Javascript (or a derivative such as JSON, Typescript,AngularJS) to/from REST APIs via TSL HTTPS links.The number of participants in the study were 15.The prototype was evaluated bya number of user questionnaires. Statistical analysis of the results found a whollypositive response as to whether the prototype could help reduce wastage. This studyshowed that a barcode scanning app could be utilised to reduce shared householdfood waste.
