They lauched this project in the Olimpic games in Rio so for now they are using the 'wasted' ingredients from the company on charge of the meals for the Olimpic Village.
The website about this project in specific is: http://www.refettoriogastromotiva.org/. The website you have is from the Non profit that offers gastronomy courses for poor people, they use dead times at universities to teach them - they are together with the project Food for Soul in this project.
Hello Julie, I just corrected the word. The app is not for trade it is for exchange or donations only! As far as I could investigate the main idea is to create this community of people who live nearby. The app is based on trusting the people. Also, by the end of each transaction you can evaluate the product and the person you did the transaction with.So I did not find inside the app a way to check about food safety so far :)
