This year’s digital cleanup campaign at the university lasted for almost an entire month, from 6 to 31 January. In total, university members freed up 4,313 GB of space on their devices and discarded 93.5 kg of old external data carriers. Prizes from the university’s gift shop were raffled among participants .
Each week, the university family dealt with a different type of digital waste. During the digital cleanup, they deleted
  • 3533.22 GB of data from their computers (about 3,600,000 documents),
  • 397.79 GB of data from their smart devices (about 400,000 photos),
  • 382.38 GB of data from their email inbox and cloud platforms (about 5,300,000 emails).
In addition, the university members deleted digital waste on OneDrive, Moodle, Panopto, BBB, Mahara, Sisu@UT and LimeSurvey.
For the disposal of external data carriers, special digital waste bins were placed in the university’s academic buildings, which received 93.5 kg of data carriers during the Digital Cleanup Month. The heaviest bin, weighing 58 kg, came from Biomedicum (Ravila 19).
The Information Technology Office thanks all participants and encourages university members to continuously clean up digital clutter to help preserve the environment. It is important to review one’s data and data carriers from time to time to prevent their unauthorised use and reduce the risk of information security breaches.
Digital cleanup guidelines and tips shared during the month remain available on the university wiki. The next university-wide digital cleanup campaign will take place in January 2026.

General principles for reducing digital waste

  • Before buying a new device, consider whether you really need it.
  • If a device does not work properly or is out of date, don’t buy a new one immediately but have it repaired.
  • If you no longer need your old device, don’t leave it in a drawer, but consider donating, selling or recycling it.
  • Choose an energy-efficient product that has a long lifespan and is made from sustainable materials.
  • Use cloud services, as storing data in the cloud reduces the need for physical storage space.
  • Reduce unnecessary data storage.
