Campaign Month "Sustainable September"

The University of Bonn invites all its members to take part in the many varied initiatives and events about sustainability as well as to come up with ideas for own campaigns.

RhineCleanUp: September 10

Each year, enormous amounts of waste end up in the oceans. Millions of tons of plastic pollute the environment, with a majority of waste entering the oceans via rivers. Against this backdrop, the University of Bonn will be participating in this year’s RhineCleanUp event again and is inviting all of its members and their families to join in.

We will clean up the Rhine from head to mouth by removing trash from the riverbeds. The project aims to raise awareness that waste must not be thrown away carelessly or, even better, that it should be avoided in the first place.

Saturday, September 10

10:00 am to 2:00 pm 

Meeting point: “Beueler Bahnhöfchen” Restaurant, Rheinaustraße 116, 53225 Bonn-Beuel

We will be providing gloves and trash bags, but feel free to bring your own gloves or equipment.

To facilitate planning, please register in advance via email

Anyone who’s dropping by spontaneously is just as welcome!

We can’t wait to see you!

Register to join Team Uni Bonn for City Cycling—including prize draw

Did you know? We did fantastically well in last year’s City Cycling competition: second in the overall rankings for Bonn, third-largest team and best individual cyclist. But this year we want to go one better! Team captain Benjamin Grimm is happy to welcome anyone taking part: “Beating the best  riders is a bit like wanting to knock Bayern Munich off topspot,” says the keen racing cyclist with a grin. “But we’re really good at getting the kilometers under our belts. Who knows what might happen if the University were to assemble a bigger team than in 2021…?”

You can now sign up and show your support for cycling, climate action and your own health and well being! Simply register at and spend 21 days grinding out the kilometers from September 4 onward. Each one cycled counts—not just those on the way to work. In other words, you can also include the journeys you do taking your children to their day care center, picking up rolls on a Sunday or going out for the day.

You can find out all you need to know at Please email our captain at if you still have questions.

On board? Wonderful! And might you also be interested in winning a great prize? Healthy Campus Bonn has five vouchers (including for Cook-it) to giveaway. All you need to do is tell us your favorite route by bike. What journeys are worth extending your commute home from work for? We’re looking forward to receiving bags of tips for biking in and around Bonn! Simply send a short email with your recommended trip to by September 4.

Recycling jeans: reduce clothes waste while saving resources

Like to send your old, worn-out jeans for recycling and make an active contribution to climate action in the process? No problem! From September 1 to 30, jeans and denim scraps containing at least 95% cotton can be placed in our collection bins. 

The denim used in jeans is very good for recycling. Making jeans consumes resources, particularly a lot of water. We are working together with the IGLU initiative, whose commitment and dedication has enabled no less than 7.19 tons (6,530 kg) of jeans to be collected up and sent for recycling since March 2020. This has saved over 11 million gallons (around 43 million liters) of water and 110 tons (100 metric tons) of CO2 emissions.

Join in!

You can find the bins in two places:

  • University of Bonn Information Desk (Am Hof 1, 53113 Bonn)
  • Foyer of the lecture hall center on the Poppelsdorf Campus (CP1)

You can find more information about the jeans recycling scheme here.

Germany is saving food and WE are joining in!

Germany produces over 12 million tons (around 11 million metric tons) of food waste every year. The week-long nationwide "Germany Saves Food" campaign is taking action against food waste.

On Friday, September 30, therefore, we are offering free potatoes, apples and other food that was saved from going to waste. 

You can find us at the Kartoffelschrank (potato cabinet) on the Wiesengut farm in Endenich: Auf dem Hügel 6, INRES Institute.

From 12 noon to 7 pm, you can pick up delicious organic potatoes grown at the Wiesengut, the University’s own organic research farm. Please bring your own bag.

The so-called Drillinge (triplets) are small potatoes that are sifted out during harvest because it would be too much effort to get them ready for sale. Being too good to go to waste, of course, these potatoes are usually fed to the Wiesengut’s own cows.

You can pick apples from our orchards from 12 noon to 5 pm. Instead of ending up on the ground, the apples might then make it on top of a delicious cake or as apple sauce accompanying the first dishes of the fall.

From 4 pm to 6 pm, we will be joined by a Foodsharing Fairteiler stand offering free food that was saved from going to waste. The stand is operated by our partner "NEiS: Nachhaltige Ernährung im Studienalltag" (sustainable everyday eating for students), an initiative of the Verbraucherzentrale NRW consumer association.

We can’t wait to see you!

“Too good to go to waste!” forms part of the National Strategy for Food Waste Reduction devised by the Federal Ministry of Food and Agriculture (BMEL).

Sustainable Superfood: Preserving Like Gran Used to Do

Talk and workshop on preserving fruit and vegetables in the fall. This event is organized by CampusAckerdemie, Biology Didactics and the NEiS project, an initiative of the Verbraucherzentrale NRW consumer association.

Fancy eating fruit you picked yourself come Christmas? Not a problem, provided you know how to preserve it. Curing, fermenting, drying—there are many things you can do in the fall with produce from your back garden at harvest time that will enable you to enjoy them a few months down the line.

The event is being held on September 21 (Wednesday) to coincide with the end of the CampusAckerdemie season and will be in three parts:

  • Farm visit (4 pm to 5 pm): How can you grow your own fruit and vegetables? We’ll show you our very own CampusAcker farm, where trainee teachers learn to do exactly that so that they will be able to plant or look after their own school garden one day. (Participation optional—no need to register)

Meeting point: CampusAcker, behind the lecture hall center on the Poppelsdorf Campus

  • Talk (5 pm to 6 pm): Michael Bonke will explain various techniques for preserving fruit and vegetables. (no need to register)

Meeting point: Botany lecture hall (Nussallee 4, 53115 Bonn)  

  • Workshops: Following on from the talk, discover the art of fermentation.

Meeting point: Botany lecture hall (the workshops will be held in classroom 2 in the Nees Institute)

  1. Workshop: 6 pm to 7 pm
  2. Workshop: 7 pm to 8 pm (will only take place if there is high demand)


You will need to register in advance using this link.

+++ The deadline for registration is Monday, September 19, 12am +++

Please also bring along the following utensils to the workshop:

- Chopping board

- Largish, sharp vegetable knife

- Vegetable slicer or mandoline

- Large bowl (for kneading sauerkraut)

We look forward to seeing you on September 21!
