Protecting the environment and saving resources

Organic, regional and Transfair

Studierendenwerk Essen-Duisburg holds organic certification by DE-ÖKO-039. It uses fairly traded coffee products and work with regional suppliers as a matter of principle.

Waste prevention and green behaviour

We separate waste in all our facilities. Food waste, oil and fat are collected by specialist firms for energy conversion. Foodstuffs are supplied in bulk containers. To reduce transport distances, preference is given to regional suppliers and producers.
To minimise waste we also have a returnable bottle system in operation, and we use resource-saving recycled paper for hygiene products. Energy efficiency is optimised in the main dining hall with Sicotronic and photovoltaic systems.

Reusable deposit system in the cafeterias

In order to reduce the consumption of paper cups on campus, the Studierendenwerk Essen-Duisburg cooperates with a cup deposit system of CUPFORCUP. In the cafeterias of the studierendenwerk (Exception Caschü & Bistro Zollverein) customers can get a reusable cup for 1-Euro deposit at the cash desks and use or return it as often as they like.

The system is very practical as the cups can be returned to other participating companies beyond the campus. The reusable cup not only protects the environment but also the wallet. There is a discount per hot drink.This discount is valid for your own as well as borrowed reusable cup.

Coffee grounds as fertilizer

The Studierendenwerk Essen-Duisburg sells about half a million coffee drinks per year in its canteens and cafeterias. Up to 30 litres of coffee grounds are produced every day. This coffee grounds can be collected free of charge and used as fertiliser, for example. In just the same way as commercial mineral fertilizers, coffee ground contain nitrogen, potassium, phosphorus and other important plant nutrients. If you are interested, you can pick up the coffee grounds during the regular opening hours at the cafeterias of the Studierendenwerk Essen-Duisburg. For transport 10-litre buckets with lids are provided. Only a phone call to the cafeterias' contact person the day before is sufficient.
