Abstract
Globally, food waste from school lunch programmes varies considerably, ranging from 33 to 116 g/student/day, with vegetables the most wasted food category(2). In New Zealand, the Ka Ora Ka Ako school lunch programme provides free healthy lunches to schools whose communities face greater socio-economic barriers. The programme has been criticised with claims that large quantities of food is wasted, although there is no available data available to support these comments. The aim of this study was to measure the quantity and destinations of food waste from the Ka Ora, Ka Ako school lunch programme in Dunedin schools. A total of eight primary schools in Dunedin participated. At each school, data was collected over four days: the first day was an observation day and on the remaining three consecutive days food waste was measured. Equipment (e.g., measuring scales, buckets and containers) was used for direct weighing and to carry out the waste composition analysis (i.e., manually sorting waste by type). Data was recorded and analysed using Microsoft Excel software. School rolls ranged from 17 to 353 students. Across the seven schools, the total amount of food waste from leftovers was 5274 g/day, with a mean of 32 g/student/day. Destinations of food waste from leftovers varied, ranging from returning to the supplier to being disposed in school rubbish bins (to landfill). Using the Target, Measure, Act approach recommended for food waste, the ‘Target’ is to halve per capita global food waste at the retail and consumer levels by 2030(2). This study contributes to the second step, which is to ‘Measure’ food waste. The findings from this study may be used for the third step, ‘Act’, to reduce food waste from the Ka Ora, Ka Ako school lunch programme, diverting this from landfill.
