Swedish pupils to participate in research to reduce food waste

Press release 4 June 2020

Can more information result in less food being wasted? Researchers will be investigating this together with pupils and teachers across the whole of Sweden in the ’Food Waste Experiment’. To assist them, they will be using an artificial intelligence app and the world’s largest food sustainability database.

Our food is responsible for over one-third of human-caused climate emissions.* At the same time, almost one-third of food produced globally is thrown away.** In the Food Waste Experiment, researchers will be testing a new way to reduce food waste in Swedish schools: by providing more information and feedback to pupils.

Pupils and teachers will be able to see exactly how their food choices and food waste are affecting the climate.

“We hope this can lead to more climate-friendly food choices and less food waste,” said Björn Hedin, a researcher at the Department of Human Centered Technology at KTH Royal Institute of Technology in Stockholm.

An app to calculate the waste

In the Food Waste Experiment, pupils can use an app to find out how much food they are throwing away. They photograph their plates before and after eating, and then the app calculates how much is being wasted. Before lunch, they receive information about the day’s menu being served in the school dining hall, the nutritional content of the various dishes and their climate footprint. The information comes from the world’s largest database on factors relating to food and environmental impact, health and justice, developed by the company Consupedia in collaboration with researchers at Dalarna University and KTH Royal Institute of Technology.

Creating virtuous circles through feedback

Through the project, researchers want to test whether it is possible to create virtuous circles in how food is dealt with – from wholesalers through to pupils. Making pupils more aware of how their food is affecting the climate, health and the environment, can lead to more thoughtful choices in the dining hall. As school kitchens get better information about what food the pupils like and dislike, menus can be adapted to better suit the needs of the pupils. The kitchens can then make more tailored orders from the wholesalers, so that the amount of waste is reduced both in school kitchens and at wholesalers.

“We hope that as many schools as possible will take the opportunity to join The Food Waste Experiment and carry out research to create a sustainable future. The more pupils that participate, the better results we can get,” said Roberto Rufo Gonzalez, a researcher and project manager at Consupedia.

Citizen science for a sustainable future

The Food Waste Experiment is an example of citizen science, whereby researchers enlist the public’s help to address issues that they cannot investigate on their own. For pupils, it is an opportunity to participate in real research, while teachers get access to research-based material to incorporate into their teaching.

“In our previous citizen science projects for schools we have seen that pupils really appreciate doing something that is actually ”real”. In The Food Waste Experiment, they are helping to develop new knowledge that can be used to tackle a current societal challenge,” said Fredrik Brounéus, a Researcher and Press Officer at VA (Public & Science).

The Food Waste Experiment (’Svinnkollen’ in Swedish) is being carried out between 9–27 November 2020 and is a collaboration between Dalarna UniversityKTH Royal Institute of Technology, the company Consupedia and VA (Public & Science). The project is being funded by the Swedish Energy Agency and Consupedia.
