Bridge&Tunnel

Together with Hanna Charlotte Erhorn, Constanze Klotz founded the textile manufacturer Bridge&Tunnel, which has been combining circular fashion with social impact since 2016. The manufactory produces exclusively from post- and presocnumserwaste. And it does so in the middle of Hamburg with socially disadvantaged women, many of whom have an immigrant or refugee background. In this way, Bridge&Tunnel helps valuable material resources to a new life in style and hopeful talents from all over the world to a fulfilling job with recognition.

Represented in the following tracks at the next Sustainability Summit:
