We urgently need to learn how to close cycles! Human society is approaching a situation where several resources are becoming scarce at the same time. Climate change is increasing the pressure. Wealth and well-being of coming generations will depend on our reactions.

Closing material cycles in a safe and sustainable way is a challenge. Complex problems are ahead of us and a broad, integrative approach is needed to tackle them. The tight collaboration of architects & planners, scientists and engineers will be crucial in this process.

The International Ecological Engineering Society IEES believes that ecology is a key competence for future professionals. It teaches how to deal with complexity and requires a mode of thinking in systems at different scales. Sustainable solutions need to be inspired by a profound understanding of material cycles, ecological functions and - principles.

Zurich University of Applied Science in Waedenswil, Switzerland, and IEES will host the 2020 Closed Cycles and Circular Society Symposium on 2-5 September 2020. The symposium directs to foster the most recent practices, innovations and challenges encountered in this field.

We aim to address professionals, such as scientists, planners, architects and engineers, who are interested in finding solutions adopted in the field of ecological engineering. We cordially invite you to participate in this unique symposium to exchange knowledge, innovative ideas and creative skills for an integrated, holistic design.

In the Call for Tasks & Case Studies and the Call for Sessions we received 15 submissions! The review is not yet completed (state of Feb. 2, 2020)

The Call for Abstracts is now open until March 2, 2020.

Tasks, sessions and the whole symposium are designed to allow ample time for discussion and exchange.
No "Sorry, there's just time for one question" at this symposium!

Each Task- and Session proposal should focus on at least one of the following key themes:

  • Integrated (holistic) design and planning
  • Green buildings & infrastructure
  • Avoidance strategies
  • 100% Renewable energy strategies
  • 100% Closed-cycle strategies
  • Value chains with ecological engineering
  • Multifunctional systems
  • Managed biological and ecological systems
  • Nature-based solutions
  • Advanced tools for ecological engineering
  • Environmental footprint & life cycle assessment
  • Life quality aspects and ecological engineering
  • Ecological Engineering Education
  • Transfer of ecological findings to human society

If you do not find your key theme, we invite you to propose another key theme to the organizers.
