well, it's a website for an app-based service, but I still think it deserves recognition.
TooGoodToGo helps fight food waste by letting you pick up packages of discounted food nearing its expiration date from local businesses: https://toogoodtogo.com/
Wow, this is excellent! I was sort of wondering whether the leftover bread and pastries from the shop nearby got donated or something, but apparently they and the little supermarket next to them are both listed in the app and sell their leftovers at 6.30 each morning to anyone who wants them. This could end up being dangerous (loads of pastries for less than two euro for the lot)!
