Join Luxembourg’s annual spring cleanup, also known as the “Grouss Botz” with Shime, Serve the City Luxembourg and CSFN! Continuing a 50-year tradition, we aim to reduce the 1001 tonnes of litter that are dumped every year in our beautiful country. With our cleanups we protect our country’s charm and wildlife. If you didn’t know about the Grouss Botz, your commune is probably participating so please feel free to ask them.


📍 In Luxembourg we generate 1.6 KG of wild waste per cápita, per year.

🛣️ 100 to 200 KG of litter are collected per 1 km of road every year in Luxembourg. (see report)

💰 In Luxembourg, roadside cleaning costs reach about 1.2 million euros per year.

🐠 By 2050, our oceans could have more plastic than fish (80% comes from land) 


Participate in the Grouss Botz in your commune. We have prepared for you a list of communes that run the Grouss Botz in 2024. In case your commune does not participate, this shouldn’t stop you from participating; you can always get out there with some gloves and bags to make a difference using the CSFN app. Let’s unite, Luxembourg, to keep our environment clean for us and future generations.
