Imagine having a day to gather your friends, neighbours and acquaintances to improve your own city’s quality of life and keep it clean while also protecting the environment. That’s the idea behind World Cleanup Day, a global event held in over 180 countries in which more than 50 million people have participated since 2018.

In Belgium, 100,000 volunteers across the country took part in the fourth annual edition of the global event on Saturday, 18 September, mobilising city administrations and civil society alike.
