Meat food waste in households - Using discrete event simulation to provide an evidence base for reducing global household meat waste

Reynolds, C. ORCID: 0000-0002-1073-7394 (2021). Meat food waste in households - Using discrete event simulation to provide an evidence base for reducing global household meat waste. Paper presented at the 67th International Congress of Meat Science and Technology, 23-27 Aug 2021, Kraków, Poland.

Abstract

Of the 1.3 billion tonnes of global food loss and waste, meat waste is estimated to be 4%. This is equivalent to ~19% of global meat production, and is linked to much of the greenhouse gas emissions and other environmental impacts related to food loss and waste. One method to reduce the environmental impact of meat is to reduce global food loss and waste. To highlight the global scale of this challenge, this keynote presents the results of a 9 country pilot survey (Brazil, Ghana, India, Kenya, Nigeria, Argentina, Colombia, Peru, and the UK). The results show how different shopping, cooking and packaging options drive household beef and chicken waste. This keynote then proposes possible solutions to reduce household meat waste, including product shelf life extension; changing purchase, consumption, and freezer use behaviour; and packaging and portion size modifications. These interventions have been validated using the household simulation model - a discrete event simulation model that replicates the stages and processes of home food purchase, storage, consumption and disposal. Examples of the scale of household waste reduction impacts are given for Chicken breast and Bacon in the UK.
