Nutrition quality and food and packaging waste associated with the school food system: A pilot, citizen science study in an Irish secondary school

Abstract

AbstractBackgroundSchool is an important setting for creating healthy and sustainable food environments. Using participatory methods, this pilot study examined food and packaging waste and nutrition quality within the school food system.MethodsOne secondary school in Ireland participated in a waste audit. Eleven male students (15–17 years) participated as citizen scientists. Students collected waste over 1 day and documented data on waste categories. Nutrition labels were photographed for analysis. Students created a video and participated in a focus group. Quantitative data were summarised using descriptive frequencies. A Nutrient Profile Model was applied to summarise nutrition quality. The focus group discussion was analysed using content analysis.ResultsHighest weights of waste were organic waste (14.2 kg), paper and cardboard (5.0 kg), and hard plastics (4.1 kg). Materials banned by the European Union Single Use Plastics Directive were found. Recycling bins were contaminated with food waste. Nutrition labels from 132 food packages were analysed, of which 115 items (87%) were low‐nutrient, energy dense foods. Confectionary, energy bars and desserts and savoury snacks were the most common packaged food groups. Students were not surprised by the unhealthy food choices; however, they were shocked and saddened at the waste practices. Their proposed solutions mapped across individual, community and organisational levels.ConclusionsThe methodologies allowed successful engagement with students on this topic. The use of unnecessary plastics to serve food, poor waste separation practices, and the production of avoidable waste from low‐nutrient, energy‐dense products were key issues identified. Students proposed solutions that are achievable in the short‐term.
