Tackling food waste on Campus
In order to contribute to reducing food waste, USJ has introduced a food waste monitoring system developed by Winnow Solutions in Ilha Verde campus canteen in partnership with Wynn Macau.
Food waste is one of the major sources of carbon emissions and contributors to greenhouse gasses that underline the climate crisis. Also, because food is such a valuable resource, food waste in advanced economies contributes to hunger and inequality in access to basic resources. Therefore, tackling food waste can contribute to SDG 2: Zero hunger, SDG 10: reduced inequality and SDG 13: Climate action.
Macao has a serious food waste problem. Food waste corresponds to a significant portion of the waste produced in the city. The waste produced per capita in Macao is higher than the waste per capita produced in cities with the same characteristics, such as Hong Kong and Singapore.
In order to contribute to reducing waste among our students, University of Saint Joseph (USJ), in partnership with Wynn Macau, has introduced a food waste monitoring system developed by Winnow Solutions in our campus canteen. This system uses a scale and an artificial intelligence to detect the amounts and types of food discarded after each meal.
By sharing this data with the university’s community, we aim to increase the awareness of students and staff to the food they waste. Additionally, this information is also used by our canteen provider to optimize their menu and portions. By applying this system, we aim to reduce food waste by at least 10% within this school year. Additionally, by raising the awareness of our students we hope that they became active agents of positive change in the wider community.
