Environmental awareness: Participate in CERN’s “Tidy-up week”

Tidy-up week

Tidy-up your work environment with a focus on recycling materials and waste

On September 18, 180 countries around the world will participate in the World Clean-up day, an annual social action with the objective of tackling the global waste problem. CERN will contribute to this effort by launching its own “Tidy-up week”, aimed at raising awareness about the need to reduce waste and properly sort recyclable materials.

CERN’s “Tidy-up week” will take place between 18 and 22 October 2021.  This first pilot edition will concern the following buildings: 5, 23, 24, 31, 54, 57, 73, 93, 104, 193, 288, 513, 561, 865, 904.

The event is carried out in collaboration with the respective Departmental Safety Officers (DSO) and Territorial Safety Officers (TSO).

What will happen?

People working in the buildings concerned are invited to identify and sort equipment and material that they no longer need in their offices, workshops or laboratories. This includes paper, metal, wood, glass or office furniture.

Please keep in mind the three Rs (Reduce, Reuse, Recycle) of waste management. The entire list of recyclable materials can be found here.

How does it work?

In the weeks prior to the event, experts will help the occupants of the concerned buildings to identify and decide the appropriate action (storage, reuse, recycling, etc.). The date of the visit for each building will be indicated on the dedicated webpage.

During the week of the event, skips and containers will be available close to the concerned buildings for the disposal of equipment and material. A transport team can help remove more voluminous objects.  In this case, a transport request needs to be filled in beforehand (the procedure is described on the dedicated webpage).

Your building is not on the list?

This event is a pilot, and more buildings will follow in the future. If you’re interested in joining the effort, please contact the coordination group at tidyup.week@cern.ch.

Specific collection of IT-materials

In addition to this event, there is an ongoing campaign for the collection of IT-materials. Click here for more information on this campaign.


To protect your health and that of others please do not forget to comply with the COVID related health and safety measures, such as wearing a mask and proximeter where required.

This event is a part of the series “CERN’s Year of Environmental Awareness”.
