In order to reach as many people as possible in the project countries, project partner akaryon developed an app for collecting data from end consumers. The special feature: the partners planning activities with end consumers can adapt the surveys to their needs. On the one hand to adapt the language, on the other hand to flexibly design the questions depending on the intervention carried out.

ToNoWaste wants to learn more about the skills, possibilities and motivation of the participants. In addition, they collect and weigh the leftover fruit and vegetables over a certain period of time.

The data is anonymized and later transmitted to the ToNoWaste platform, where key figures are calculated.

The complexity of the app results not only from its multilingualism and flexible question design, but also from the fact that the questionnaire is available to end consumers in the app at fixed, predetermined times. Once before an intervention, once immediately afterwards and a third time after a month.

The end users are divided into three groups. A control group with a questionnaire only; an action group A, which experiences the intervention and an action group B, which also receives information on how much food was saved between the first and second round.

The app was used by project partner Caritas in spring and summer 2024, other partners will follow in autumn 2024.
