Closed Cycles Symposium Sep. 2020 – Join in now!

Dear IEES members and friends,

in less than three months the Closed Cycles Symposium will start ( Preparations are now advancing quickly. Here’s a brief update:

The symposium was turned into a 100% online event in March. It will be powered by the next-generation conference software “Talque” ( ). Talque offers a great deal of bilateral and multilateral communication and exchange options. Only a small control center will remain in Switzerland.

The switch to 100% online has been quite a challenge. The thematic focus however remains unchanged: We aim to further advance Ecological Engineering on an international level and identify “role models” for closed cycles, which are still rare in our society. We aim to explore “circular” thinking and its challenges for integrative, holistic thinking and planning. Two panels will focus on education.

The review of the abstracts has been almost completed, and most presenters have been notified. So far we approved 4 keynote speakers, 3 panel discussions, 10 scientific sessions with about 30 speakers, 19 tasks & case study workshops and 10 posters.

There’s still room for additional tasks and case studies as well as for posters. Still want to submit? Late abstracts are accepted until June 17: The draft program will go online shortly afterwards.

Details about the task/case-study format can be found at .

Proceedings: A Special Issue proposal has been submitted to a journal. Details will follow as soon as it is approved.

Registration is now open: Early bird fees are valid until July 10. IEES members profit from a 25% reduction.

We also cordially welcome two more co-organizers: Reijkjavik University ( and AEES ( The latter is in the process of organizing two sessions of the symposium.

Last, but not least: We now offer a sponsoring plan, giving you the possibility to make your business visible to the conference participants. Please contact us, if you are interested.

All the best and stay healthy in these turbulent times
