We are participating in the German Action Days for Sustainability. Once again this year, all committed initiatives, organizations, and groups are invited to demonstrate how the 17 Global Goals for Sustainable Development (SDGs) can be put into practice in everyday life with creativity and initiative—whether locally, within the community, or across Germany.


The Action Days will take place from September 18 to October 8, 2026.

Bottle cap collection drive

Join us! We're collecting bottle caps with the E. Kraus container service from Langelsheim for the "Elternhaus" run by Elternhilfe für das krebskranke Kind Göttingen e.V.!

German Sustainability Action Days will take place from September 18 to October 8, 2026. During this time, we’ll be collecting bottle caps (no plastic caps) at our Green Office (main building, room 152). If you’d like to participate, just bring your bottle caps  (no plastic caps) by. We’ll hand over what we’ve collected by September 25, 2026, to the recycling service at the Future Festival in Goslar on September 26, 2026. Anything we collect after that will be dropped off in Langelsheim once the campaign period is over.

Keep using your glasses!

Is your eyesight getting worse and worse, and do you need new glasses? What should you do with your old glasses? They’re still in good condition. It’s just that the glasses no longer work for your eyes—or rather, your eyes no longer work with the glasses!

During the German Sustainability Action Days, we’re collecting used but undamaged glasses. We’ll take the collected glasses to a drop-off point for “Brillen Weltweit,” a campaign run by the German Catholic Association for the Blind (Deutsches Katholisches Blindenwerk e.V.).

Please bring only undamaged glasses without cases.
