On Thursday 26 June 2025, we brought together the members of the Business Club for their annual summer workshop. It was a great opportunity for discussion and collaborative work, in line with the Club’s objective: to challenge businesses to reduce their use of plastic and implement effective reuse solutions.
The workshop brought together participants from different departments, as well as new members, providing a valuable opportunity to meet, share the latest news and take stock of the actions carried out within the College.
The morning was devoted to a round table discussion bringing together perspectives from science and business, with contributions from Thomas Bou, Constance Cornemillot, François Dedieu and Mathis Grossnickel.

The afternoon gave way to a collaborative workshop dedicated to the conditions for successful reuse. Drawing on the lessons learned from the round table and their own experiences, the participants worked collectively to:
The workshop concluded with a collective feedback session, allowing participants to exchange views and open the discussion on the next steps for the Business Council.
Many thanks to all the participants for the richness of the exchanges, the quality of the contributions and their constant commitment to working together to build ambitious and operational solutions to reduce plastic pollution.
