Switzerland’s most sustainable concrete

Circular economy as an opportunity for cities

Language: German

Circular economy is an enormous opportunity for cities. To successfully implement a circular strategy, it is up to representatives from politics, the local economy and the individual city to discuss the best way forward. The role of politicians is in convincing city administrations to implement the necessary measures. The aim of this session is to promote an open dialogue between politicians and the city while including the economic perspective. As that could be a driving force for Circular Cities.

The session will be held in German with contributions in French.

How a healthy diet can help the environment

Language: German

The fact that our diet not only has an impact on our health, but also on the well-being of our planet, is beyond question today. However, what a healthy and sustainable diet looks like is not quite so easy to answer. In this panel discussion, we will reflect on dietary habits with representatives from different sectors of the food industry. We want to find out to what extent they are healthy or sustainable when certain ingredients are omitted.

How circular models open new opportunities for SMEs

Language: German

The application of sustainable processes and the circular economy is already widespread among start-up companies. But for established SMEs, such rethinking of established processes often seems to be associated with great effort. However, this is not necessarily the case. This session serves as an exchange between young and established companies that have already integrated circular thinking into their business models. This way, companies will be shown proven possibilities of implementation and given inspiration to find their own way to apply circular solutions.
