A tool to calculate the environmental and economic impact of different ways to collect and process organic waste. The tool contains calculations for waste generation, transport, waste processing and application/ substitution.
PurposeFood waste is one of the most challenging issues humanity is currently facing. Therefore, there has been a growing interest in the prevention of food waste because of world hunger, environmental impacts, resource scarcity and economic costs. The purpose of the study is to investigate the factors that influence food waste and the role of technology in tackling food waste in India and the Netherlands.Design/methodology/approachIn order to explore differences in food loss and waste further this study will examine a number of practices on both the production and the consumer side, in a developing country and a developed country with different culture/economic backgrounds: India and the Netherlands. The factors that influence food waste were examined with a preliminary qualitative study, which consists of semi-structured interviews, and quantitative research that comprises a survey. Semi-structured interviews were conducted in both India and the Netherlands, which consists of five interviews. The survey data was collected from 78 individuals from India and 115 individuals from the Netherlands.FindingsOne of the main findings of the research is food waste is divided into waste within agricultural production (i.e. food loss) and final household consumption (i.e. food waste). Different factors influence food loss in different stages in the supply chain. Some of these factors include wastage during processing, storage, transportation and at the market-place. New technologies can utilize food loss for new purposes, so food loss is reduced to the minimum. Food waste is mainly influenced by food passing expiry date, food that is left too long in the fridge and consumers buying too much food. In final household consumption, technologies such as digital platforms enable individuals or organizations to share and donate their food, thereby creating awareness on food waste prevention and the environmental and ethical benefits.Originality/valueThe authors examine to what extent and in which ways supporting consumers to minimize food waste can be achieved via three stages: (1) understanding and evaluating food loss and waste, (2) identifying the factors that influence food loss and waste, (3) understanding consumer behaviors to encourage food waste reduction and (4) identifying the technological impact that would reduce food waste. As such, this paper contributes to ongoing debates about food waste by looking at the role of context and culture and by exploring differences between developed and developing countries. Also, the authors advance the debate by exploring both the role of advanced technology such as blockchain and drones in both preventing loss and waste as well as non-technological mechanisms.
The ‘dirt diary’ is a do-book that was used to interact with residents to gain a clear view on the true waste journey in households. The do-book is contains several assignments for residents around different types of waste, for example plastics, organic waste, paper and textile. Assignments include drawing a map of waste solutions in the kitchen, photographing waste generated when preparing a meal and describing how they dispose of the waste in the kitchen and at communal containers. The do-books completed by the residents were analysed by the researchers for each waste type, studying behaviour exhibited and underlying motives for that behaviour. The do-books proved to be a valuable tool to gain understanding of people's behaviour around disposing waste, the opportunities for waste separation they have in and around their homes and their motivations for separating waste or not. This should lead to touch points to create interventions on automatic behaviour so that a sustainable change in this behaviour can take place.This do-book was exhibited as boundary object at the Collaboration for Impact exhibition, eccompanying the publication Collaboartion for Impact,
