An individual or a team (school class / club / company) uses an app to keep track of the route they have cleaned from litter. The app records the route that has been run. When this route is registered, it is colored green on the map. A score is also kept of the number of meters cleaned. The goal is to get the entire village, all roads and hiking trails completely green.
After a month, a piece made green turns to orange and longer to brown. The goal is therefore not only to get the village or neighborhood green, but also to keep it completely green.
Everyone can see where the litter has been removed. Also for the municipality.
